THE Arts to 'which thefe. volumes are an intrcduBion^ are fo amiable in themfehes, and unfold fuch a va- riety of advantages and delight to mankind^ that .ive hope our endeavours to range them in a regular view, and render them intelligible even.to a moderate capacity^ will not he thought an vjineceffary undertaking. We have caft this work into the form of a Di^ionary, loecaufe we judged fuch a difpofition the mofl methodical of any, and as we arc fenfible that clearnefs of expreffwn is ef- fential to thofe performances which are publifhed with a view to illujirate the Arts andSciences, we have always endeavoured to treat our fubjeol with that perfpicuity, as we flatter our felves will not difappoint the reader's expectation of improve- ment. It has been our conftant method to confider each particular Art in the rudiinetits from which it flows, and to trace it from thofe original principles to its perfection: In the con- duct of which defign, we have advanced in that regular gradation from rule to rule, as is neceffary to convey a difiinCt idea of every circumftance which deferves obfervation, and, at the fame time, have endeavoured to preferve the due mediu?n between an affeCled concifenefs which is generally ob- fcure, and a loofe redundancy which always fatiates. We have likewife, for the fatisfatlion of the curious, given a particular account of the materials employed in thofe me- chanic arts which have a place in this work -, and have ad- ded directions for proper applications of them in every branch of the Arts to which they are appropriated : We have alfo confider ed thefe materials, not only in their firfl fhape of na^ ture, but have attended them through every procefs of art, preparatory to their lafl forms in the fhops of Colourmen, Druggi/ls, and other tradefmen ; and have laid down proper rules for diflinguifhing the pure and genuine materials from thofe which are adulterated and fpurious. As ii PREFACE. As it was our intention to render this work, at once, in- firu^ive and entertaining, we have interfperfed feveral hi- jlorical accounts of the greateft mafiers in theje Arts ; we have marked their feveral characters and peculiar turns of genius ; we have pointed out their particular method's of fiudy, and confidered the amaxing heights to which they raifed the various Arts they profeffed •, in a word, we have intro- duced all the ufefull variety we could collet, to make this article pleafe the imagination, and inform the judgment. Our ohfervaiions have been carefully collected from the mofi celebrated authors, and digefted into fuch an eafy and regular feries of infiruCtions, that thofe Gentlemen who are difpofed to confider them with attention, will he agreeably furprized at their fpeedy proficiency in fuch engaging fludies, and will find the theory and praClic part of thefe beneficial Arts attainable much fooner than they might pqffibly expeCf. We may likewife add that the expence of purchafing, and the tedious fatigue of confulting a vafi: number of volumes on thefe fubjeCts will be rendered unneceffary, ftnce we have included, in this work, all the material precepts and informations that are to be drawn from every valuable trea- tife on thefe fubjeCis, already extant. As the intention therefore of this work is to familiarife thefe charming Arts to the laudable curiofity of all who w'lfh for a competent proficiency in them \ and as we have formed it, from the beft authorities, in fuch a fyfiem of inflruClion as has a direct tendency to produce that effeU, in a more agreeable and compendious manner than has yet been at- tempted, we hope no objection of any moment can be raised againft it, to prevent its obtaining a favourable reception from the publick.

Bononias, -^ ACADEMY of PAINTING was eftablifh'd in France^ about fixty years fmce, in the reign of king Lewis XIV, under the cardinal Mazarine, the firft protedlor thereof i and the chancellor Seiguer, vice-protedlor. It confifts of a diredlor, a chancellor, four rectors, ^ trea- furer, twelve profefTors ; counfellors, a fecretary ; a profeilbr of anatomy, another of geometry and perfpe(Slive. Perfons are admitted into this academy, either in quality of Painters or Sculptors. The Painters are admitted accord- ing to their refpe£live talents ; there being a diftihcSion made between thofe who work in hiftory, and thofe who only paint, portraits or landskips, or beafts, or fruits, or flowers, or paint in miniature, or only defign ; or engrave or carve, ACHELOUS the river, is defcrib'd by Oz;/^ adorn'd with a garland of reeds willow and the like : having two urns or ear- then pitchers, the one empty, and the other pouring forth water ; and having on his head two horns, the one broken and the other whole. This river as it is the moft famous of all Greece, Co it di- vides /Etolia from Arcadia^ and then falls into the fea. Vol. I. B Thij IL s This reprefentation is taken from the fable of Hercules^ who combated him in the likenefs of a bull for the fake of his v/ikDejanira^ and broke one of his horns; there turning both its ftreams into one, for which reafon one of the urns is reprefented empty. ACTION in Painting and Sculpture is the pofture of a figure ; or the action it is fuppos'd to be in ; exprefs'd by the difpofition of its parts, or the paffion appearing in its face, fee ATTITUDE and EXPRESSION. A. D. J. F, fignifies Atithony J ac quart fecit. He engrav'd feveral pieces. ADAMO, a fculptor of Mantua, engrav'd the angels of Michael Angela Buonoroti^ in feventy three plates, and work'd for other matters, and mark'd his plates with the mark. See plate No. i. iEGIPAN, [of 'A('|^»y«f, gr. a goat] a denomination given to the Hf'?.then god Pan and the Panes, on account of their being reprefented in painting with the horns, legs, feet, l^c. of that animal. . Salmafius in his notes on Solinus, takes ^gipan to have fig- nified the fame in Lybia with the Sylvans among the Romafis, Vojfius oppofes this opinion, and ihews that the /Egipanes had not faces like men as the Sylvans had j but like Gods. In efFe<5l the whole upper part of the body refembled that animal j and as to the lower, they painted it with a filh's tail. ArE. ADAM .ELZHEIMER, who wrought with P^- ter Bruguel, mark'd his pieces with the preceding mark. See plate No. i. yENEAS, the Trojan prince, is painted in a purple man- tle trim'd with gold. iEOLUS is depicted with fwoln, blubb'd cheeks, like one that with main force ftrives to blow a blafl: ; two fmall wings upon his fhoulders, and a fiery, high countenance. He is by the poets feigned to be the g'd and ruler of the winds, ivhofe defer ipt ions are to be found under their proper articles al- phabetically. ^S USTUM, to make. Take bits or thin leaves of cop- per fifteen ounces, fulphur in powder ten ounces, fea fait finely powdered fifteen ounces, fill the crucible by laying in layer upon layer ; put it into a furnace of live coals, and let it (land till the fulphur is v/holiy confum'd; then take it out, and it will be of an iron grey, but reddifh within ; it gives a noble fine tindure to glals. A F R Another HLa Uftum. Take thin plates of the reddeft copper (/'. e. the rofe copper) make it red hot, and extinguifh it in urine, in which common fait has been diflblv'd : reiterate this operation till it becomes of the colour of gold, both with- ( in and without ; after which cement thofe places with this ' powder. Or Take fulphur two pound, fait petre two pound, vitriol calcin'd tp rednefs one pound, reduce all to a powder, put the plates with the powder into a crucible layer upon layer, cover it with another crucible having a whole in the bottom, lute them together, and being dry, put them into a circulatory fire^ (having hot embers underneath) for fix hours : for the lirft two hours let the fire be a foot diftant from the crucible j ( the fecond two hours let it be half a foot from the crucible, and the laft two hours let it be clofe to the crucible, cover it. Take care that the fire be not too violent, that the matter may not melt, for if it does it is fpoil'd. When it is cold re- duce it to a fine powder, wafh it, dry it, and keep it for ufe. There are other curious perfons who make an Ms ujlinn^ . yet finer than this, and more penetrating in colours ; but the I preparation is more coftly and requires more time; forinftead. I of brimjione zndfalt-peire, they make ufe of a purified y«/- phur, and fix'd vj'wh fal-armoniac j and inflead of ordinary icd \ vitriol they ufe Ro7nan vitriol^ which they prepare with the ', lee of urine, and a fufil fait; which they afterwards put into a reverberatory. But fince the before mentioned will ferve well enough for colouring glaf^, and are eafier to make, I (hall omit giving the preparation of this. A. F. is a mark found in fome plates of Albert Durer. AFFECTION in painting is defcrib'd like a comely an- cient lady, winged, holding in her hands a woodcock, and at her feet a lizard. Her age (hews fhe is conftant, winged becaufe affeilion is produc'd in an inftant, the cock and lizard are emblems of good will by inftincS; her pofture fiiews, that benevolence between two for a long time, becomes at laft one true friend- Ihip. AFRICA is reprefented by a Blackmoor woman almoft naked, having frizzled hair, an elephant's head for a creft, a necklace of coral, and pendants of the fame ; at her ear a fcorpion ; holding in her right hand a cornucopia^ with ears of corii in her left hand ; a fierce lion by her on one fide, and a viper and ferpent 00 the other ; (lie is naked, becaufe it does not B 2 abguni A G R aSound with materials for clothing ; the elephant Is an animal with which Africa abounds j as it alfo does in vipers and fer- pents. A. G. ftands for Albert Glochentonlus^ in the twelve plates reprefenting our Saviour's paffion. AGATE, a precious ftone partly tranfparent and partly opake. There are various kinds of Agates ; which according to their colours, degrees of tranfparency, iJc. have different names ; as the onyx, the chalcedony, the black and the Ger- man-Agates. The Agate has commonly a reddifti teint; but is finely variegated with fpots and ftains, many of which feem very naturally to reprefent woods, rivers, trees, flowers, fruits, animals, ^c, Thefardines and fardonyx Agates are very valuable, the latter is of zfanguine colour, and is divided into zones which feem as if they had been painted by art. Agate has always been elteem'd for feals, as being a ftone that no wax will ftick to. Gold wire drawers burnifh their gold with an Agate, whence the inftrument us'd for that purpofe is call'd an Agate. AGE in general is reprefented in painting by a lady in a garment of three colours, holding up her hands, with a fun in her right hand, and a moon in her left ; the right being higher than the left ; and below a bafilisk eredled. The changeable habit denotes the changing of the minds and purpofes of feveral ages ; the fun and moon intimate their regulating the three principal members, the head, heart and liver, where the vital, animal and natural virtues refide. ROBERT AGGAS, a good Englijh landskip painter both in oil and diftemper ; very skilful in architecture, in which kind he painted many fcenes for the play-houfe in Covent- Garden ; there are not many of his pictures extant amongft us J of thofe that are the moft confiderable, is a piece of land- skip prefented by him to the company of painter ftainers, (whereof he was a member) and which now hangs in their hall ; he was reckoned amongft the h&ii of our Englijh landskip- painters j and died in London i(>7^, and about fixty years of age. AGOSTINO a Venetian, fcholar to mark Antonio Rai- mondi in Rome, engrav'd the paintings oi Raphael Julio Romano, and others, us'd the mark plate No. 2. he alfo mark'd with the letters AVI, or AV. 1525. AGRICULTURE is reprefented in painting with a home- ly ^c, but comely notwkbilanding ^ clothed in a green gown. A L G gown, crown'd with a garland of ears of corn, holding a zodiack in her left hand, and a flirub in her right; and a plough-fliare at her feet. Her verdant robe betokens hope, without which no body would labour. The twelve figns of the zodiack, intimate the different feafons which the tiller ought toobferve; the plough is the moft neceflary inftrument in agriculture. A. L. P. I. ftands for Anthony Llcinio Porduore inv. Ed- ward Tuahtti, (c. ALABASTER, a kind of ftone, fofter than marble, yet harder than plaifter of Paris. It is found of all colours ; fome extremely white and fhin- ing, which is the moft common ; fome red like coral ; and other call'd onyx^ from its colour ; which refembles that of the onyx, though very different from it in nature. See ONYX. Alahajler cuts very fmooth and eafy, and is much us'd by ftulptors for little vafes, columns, ^c. It is alfo fometimes employ'd like plaifter of Paris: in or- der to which they burn and calcine it; after which, mixing it up with water to a thin confiftence, it is caft in a mould, where it readily coagulates into a firm body. Francifco ALBANI a Bolognefey born In the year 1578, a difciple of the Carraches, one of the moft agreeable pencils in the woild in all parts of painting, but principally admir'd for his performances in little, and had a peculiar genius for naked figures; and the better to accomplifti himfelf for that purpofe married a beautiful woman, and us'd himfelf to the defigning of naked Fenus'sy the graces, nymphs, ^c. and little children, cupids dancing and playing in all the variety of pjftures imaginable. He died anno 1660, aged eighty two years, CHERUBINO ALBERTO Borghegiana, i. e. de Borgo, S. Sepukhi-o us'd the two marks you will fee in the plate No. 3, 4. Heengrav'd the wox\!iioi Michael Jngelodind others. ALBERT ALDOGRAFT oiJVeJiphalia, a famous en- graver, mark'd his pieces with the mark in the plate No. 5. ALGA is a plant that grows by the fea fide, and thence is call'dy^rt iveed, ox fea ?mfs ; it is found on moft coafts, and is by fome accounted the excrement or refufe of the fea. This herb, when gathered, if it be kept frefti and moift fome time, will fliew afterwards its white fait on the furface of its leaves. The inhabitants of thofe parts nigh the fea com- monly gather it together on the ftiore, and dry it by often turn- B 3 ing A L L ing it in the fun as hay is made ; after it is dry they burn it, and its alhes yield an Alkali fait, fit for making glafs and alum. The EngUjh make ufe of it for both, and call the afhes kelp. ALEXANDDR ALGARDI a fculptor oi Bologna, mark'd v/ith the mark No. 6. in a conclufion engraven by Francis du Poylli in 1653, but at other times made ufe of the fame mark, but without the G. ANTONIO ALLEGRI DA CORREGGIO, born in the year i 4.94, difciple of Frari di Modena^ liv'd in Lo7nbard)\ excell'd in hiftory painting, died in the year 1534, aged forty years. ALLUM, ? is a principal ingredient in colouring and dying ; ALUM, i neither of which in many cafes can be well perform'd without it. It is a kind of mineral fait of an acid tafte, leaving in the mouth a fenfe of fweetnefs, with a confiderable degree of aftringency. AUum is either native or factitious, the natural is found in the ifland of Milo, being a kind of whiiifh ftone very light, friable and porous, and ftreak'd with filaments refembling iilver. Faditious AUum is mr.de after different manners, according to the different materials wheieof it is made. Allufn is of divers forts, red, Roman^ plu7nofe, Jaccharine and hurrdy the three laft of which are not proper native- Allums. AUum is principally produc'd in England, Italy and Flan- ders. The EngltJ}} AUum call'd alfo Roche Allmn, is made from a bluifh mineral ffone found plentifully in the hills of Tork- J}:ire and Lancajhirc. The flone they calcine on a hearth or kiln, and fteep it fucceffively in feveral pits of water ; and then boil it for about twenty four hours : laftly, letting if fland for about two hours, the impurities fubhde and leave a pure liquor; which being re- mov'd into a cooler, and fome urine added to it, begins in three or four days to gather into a mafs; v.'hich being taken cut, wafh'd and melted over again, is fit for ufe. In the AUum works at Civita Vecchia, the procefs is as fol- lows: The lione, which is of a ruddy hue, being calcin'd, they boil and diffolve the calx in water; which imbibing the fait, i. e. the ^//////.', fepaiates itfelf from the ufelefs earth. Laftly, leaving the water thus imp .egnated with fait to ftand fome time, it cryflaliizes of iti'elf, like tartar, about a butt, and ijiftkes what they call Roche or Roman AUum, The A M A The Swed'tjh Allum is made of a mineral which contains ^ great deal of fulphur and vitriol, not to be taken away j but by calcination or diftillation. The maiter remaining in the iron vefTels, us'd in feparat- ing the fulphur from the mineral, being expos'd to the air for fome time, becomes a kind of bluifh afhes, which they lixiviate, cryftallize and convert into Allum. Allum in colouring and dying, ferves to bind the colour upon the ftufFs, and hp? the fame ufe there, that gum water and glutinDus oils have in painting; it likewife difpofes fluffs to take colour, and adds a degree of brisknefs and elegancy to them, as is feen vifibly in cochineal and the grain of fcarlet. It alfo preferves paper, that has been dy'd in its water, from finking when wrote upon. ALLUM V WATER, boil four ounces of ^//«/n In a quart ALUM 5 of rain or river water, till the Alhan is dif- folv'd and let it fland twenty four hours. With this water wafli prints ycu defign to colour, and it will fix the paper fo, that the colours will not fink or run in it, when you lay them on, and will help likewife to brighten your colours. If your paper is very thin and loofe, then wafh it with this Alluyn water four or five times, letting it dry between every time, and your paper muft always dry before you lay on any of your colour?. Eut take notice, that if you deagn to varnifli your prints after they are colour'd, then wafli the prints all over equally with white itarch before you colour them, and when that is diy lay on the coiours. The method /;z^r, ofeach an ounce: calcine gently, till the fulphur is confum'd, and fo will the Aurum [gold] fticlc to the upper cruft or fcoria. This being finely powder'd, and ground with glair, will with pen or pencil give your figure or picture a golden colour. See 2d. Ed. Pharm. Bat. AUTHORITY, is reprefented in painting like a grave ma- tron fitting in a chair of flate, richly cloth'J in a garment em- broider'd with gold, holding in her right hand a fword, and in her left a fcepter, and by her fide is a double nophy of books and arms, D 3 Her BAG Her age and gravity indicates Authority^ as alfo do the throne on which fhe is feated, and the fplendid habit the pre-emi- nence perfons in Authority have over others; the fword lifted up denotes fovereign power, and the fcepter is alfo an enlign of Authority. AUTUMN, is reprefented in painting by a man at perfect age, cloth'd like the vernal^ and likewife girded with a ftarry girdle; holdisg in one hand a pair offcales, equally poiz'd, with a globe in each ; in the other a bunch of divers fruits and grapes. Moll: of thefe are explain'd in the vernal^ they being the fame. The age denotes the perfeSiion of this feafon, when fruits are ripe. The balance or libra is one of the twelve figns of the zo- diack, which denote Atituinn. AZURE, a mineral colour, prepar'd from the lapis Armenus Az.ure^ is very near of kin to ultramarine ; being procur'd from the Armenian ftone, much after the fame manner as the other is from lapis lazuli. See p. 132. To dye an AZURE Colour. Take roche allum and filings of brafs of each two ounces, hfli-glue half an ounce, vinegar or fair water a pint, boil it to the confumption of the half. B. fiands for yohn Sebald Beham. Abbot Primaticcio^ who in France was call'd of Bologna^ alfo us'd the letter B for his mark. So alfo did // Bonafoni, and fo alfo did Domcnico Becca- fumi interfedling it with a line. B. B. fignifits BariholAnevj Bcham of Norimberg^ he en- grav'd at Rcme and in Bologna with Mark Antonio Raimondi.. The fame letters were alfo us'd by Barthokiv Bijcano a Genoese painter, in fuch plates as were of his own invention. B. B. A. F. fignifies Baccio Bandinelli a Florentine Architect. I. BACCHUS. Phikjlratus tells us that Bacchus was form'J in the iikenefs of a young inan without a bt-ard, of a coi'pulent and grofs body, his face of an high colour and big ; his head adorn'd with a garland of ivy leaves Jiaving on his temples two horns ; and clofe by his fide a certain bcalt, cali'd a Leopard 01 panther. This defcription is taken from the nature cf ivine (oy which ac- cording to the ji^ion of the poets, Bacchus ivas the God) whofe in- 'venier and finder out was certainly Noah, as not only Mofes, but Jofephus and La6tantius ajfirnii vjhence he is by many juppos'd to. be this God Bacchus. II. Claudianus relates that liis image or flatue was made all nfikcd ; which indicated the nakednefi. of thofe, who abufe them- felves BAG iclves with wine; by which means they reveal and open thofe things which ought to be conceal'd and kept hid. III. Diodcrus Siculus relates, that Bacchus among the Greeks, v.as reprefented in two feveral forms ; the one as a very aged wuin witii a long beard, ftiff and thick, the other of youthful years, of a pleafant and amorous afpecl. The frji form intimates the effects of the intemperate ife of wine ^ which wears nature^ and brings old age along with it ; the ether Jhews^ that it cherijhes and revives the hearty if moderately tisd, IV. Macrobius informs us, that Bacchus was fometimes repre- fented in the likenefs of a young child j fometimes of a youth, fometimes of a man ; and fometimes in the likenefs of decrepid old age. By thefe were f.gnified the four feafons cf the year, the vine be- ing dedicated to Sol, in whom they all exrji. V. Philojiratus like wife tells us, that Bacchus was oftentimes drawn cloth'd in women's garments, and in a long purple robe ; his head adorn'd with a coronet of rofes, with companions and followers all of them in like loofe and wanton garments ; ha- bited fome of them like rural nymphs, as the Dryades, OrcadeSy &c. fomc like fea nymphs, as the Nereides, Syrens, Sic. fome like Satyrs, Fawns, Sytvans, &c. The tvo?nen^s garments indicate, that luine makes a jnan faint, feeble and inconjiant like to a woman. VI. Paujauias fays, that the Eleans pictured Bacchus with a long beard, cloth'd in a long gown, hanging down to his feet j holding in one hand a fharp hook, and in the other a bowl of wine, and many vine-trees and other fruitful plants round about him. VII. The Cyrenians, a people inhabiting the further parts of Perfia, depicted Bacchus in the likenefs of a bull. By this was intifnated that Proferpina (the daughter o/" Jupiter) brought him forth in that form. VJII. The ftatue o^ Bacchus, was alfo fometimes fet forth and adorn'd with garlands made of fig-tree leave?, in comme- inoration of a nymph (as fome fay) call'd Pfycbe, who was by the Gods metamorphos'd into that plant. In like manner the nymph Staphilis (with xvhom Bacchus was alfo enamour d) was transformed into the vme^ from whence it is that thofe plants are fo exceeding grateful and pleafant to this God. IX. Bacchus is panned with ihort brown curl'd hair, cloth'd with either a Leopard'^ skin or a green mantle, a tawny face, with a wreath of vine branches. BACK PAINTING, Metzo-tinHo prints ivith oil colours. This art conlifts chiefly in laying the print upon a piece of clear crov/n or Cick-hill ghfs, of fuch a fize as fits the print. D 4 In B A C I In order to do this, take your print and lay it in clean water for two days and two nights, if the print be on very ftrong, clofe and hard gumm'd paper, but if upon an open, foft, fpungy paper, two hours will fometimes fufficc, or more according as the paper is. The paper or pifture having been fufEciently foak'd, take it out and lay it upon two (heets of paper, and cover it with two more, and let it lie there a little to fuck out the moifture. In the mean time, take the glafs the pi£lure is to be put upon, and fet it near the fiie to warm, then take Strasburg turpentine, and it being in a gallipot, warm it over the fire, till it is grown fluid, then with a hogs hair brufli, (the hairs of which have been weU faften'd by wedging) and with that fpread the turpentine very fmoothly and evenly on the glafs. When this has been done, take the metzo-tin£to print from betwe.n the papers, and lay it upon the glafs ; beginning firft at one end, rubbing it down gently as you goon, till it lie clofe, gnd there be no wind bladders between. Then with your finger or fingers, rub or roll off the paper from tht backfide of the print, till it looks black, /. e. till you pan fee nothing but the print like a thin film left upon the glafs, and when you have done this, fet it by to dry. Aod when it is dry, varnilh it over with fome white tran- fparent varnifh, that the print may be feen through it, ahd then it is fit for Painting. Noie^ You mufl be very careful in rubbing or rolling the paper off the print, fo as not to tear it. You may inftead of foaking your prints two days and two nights, roll tJem up and boil them for about two hours, more or \&^'^ (according to the quality of the paper) in water, and that will renJtr it as fit for rubbing, rolling or peeling (as the other way,) when rubb'd with your fingers.

BANTAM-WORK, as the JAP AN- WORK, is both plain and enib'fs'd, and is wrouglit moft in gold and other me- tals. So the Bantam-Work is alfo plain and carvd^ and is wrought moft of it in cokursy with a very fmall fcattering of gold here and there. II. The wood is prepar'd for this work, the fame as it is for iht Japan- IFork^ and the priming with whiting is the fame: and as to the fiat-work it is done in colours, mixt with gum- water, as the nature of the defign requires, the ordering which colours with the gum-water, is taught in Japan-Work, &c. III. The cayjdwork is perform'd after the following manner. Let either cabinet, tables, boxes, l3c. be made of deal or fome other coarfe wood ; prime it with fixe and whiting, letting it dry ; this muft be fo often repeated till the priming is almoft a quarter of an inch thick, letting it ftand to be thoroughly dry between every time. IV. But you muft take notice of this, that the whiting and fizc muft be made thinner than for Japan-Work, and for that rea- fon it muft be done fo much the oftener ; for if it is too thick, it will not only lie rougher and be apt to crack and flie off"; but it will not fo eafily penetrate to tlie bottom of any crack, nor go into any little crevice, notch or hole, as it will certainly do, if it is pretty thin. V. The piece being primed to its due thicknefs and thorough dry^ is in the next place to be water plain'd, vi-z.. to be rubb'd with a fine rag, and a little fair water j after which, being dry, rufti it as fmooth as you can. VI. That BAN VI. Then lay on the black and varn'ijh it up with a good body ; and after it has flood to dry for fix or feven days, polifh it with tripoli, water and a fine rag, rubbing it with an even, eafy and gentle hand. VII. When this has been done, trace and draw out your defign with fine cinnabar and gum-water \ in the very fame manner you defign to cut and carve it, with all the circumflantialnefs and cxa6tnefs poflible. VIII. Make your human figures^ birds, beajis and infeSls, houfes^ ireest flowers^ rocks, &ic. in their due jneafure and proportions ; the foldings of garments, leaves of trees and plants, and all other things, draw them fo, as if they vi'ere fo to remain without the leafl alteration. IX. Then being provided zvith a Jharp graver, and other cut- ting injiruments of different forms, cut out the work deep or ihallow, as you think beih but taking care never to cut deeper than the whiting lies ; for the wood itfelf ought not to be touch'd with the graver. X. Alfo leave black flrokes for the drapery and folding of gar- ments, and for the diflinguijhing of one thing from another ; carv- ing where the white is, and leaving the black untouched, ac- cording as the pattern is ; taking inftrudlions alfo from the variety of Bantam pieces, which differ vaftly from thofe of Japan, ia the very manner of the draughts, as well as in their other per- formance and finifhing. XI. The carvd work being cut out clean and f?nooth and finijh- td, and the colours well mixt, lay them into your carv'd work, with fine and clean pencils, according as reafon and the nature of the thing ftiall direct. XII. The colours being laid on and finijhed, then lay on the golden thofe places for which you defigo it ; which may be either powder gold or brajs duji, mixt with gum water ; but rather let it be leaf gold, becaufe it not only looks richefl, but is that which the Bantam artifls always ufe. XIII. But the gum xvaier it is laid with inujl be fomewhat Jironger; and muit be laid on with a pencil, and while it is jnoift the gold muft be lad on ; being firft cut with a very fharp, fmooth edg'd knife into little pieces, either on a leather- cufhion. Of on a piece of leather ftraitly nail'u to a board. XIV. Take up the gold with a little col ton, and with the fam« dab it clofe upon the work, and then (if your gujn-tvater is ilrong) it will look rich and beautiful : otherwife (if it be weak) it will appear, as if it were hungry and flarv'd when it is dry. XV. When all thcfe things harjc been done, clear up the black with oil, but without touching the colours, left you fhould rub ' them off or fully them ; for this is not fecur'd as the flat Ban- tani' ' BAR iam-tVork is ; if any wet flaould come to them, the colours would fpoil and come off. Jn this cafe it is beft to leave out the tarnijhing colours, and only ufe fuch as you may apply the fecuring varnijh to without lofs of their fplendor and beauty. JOHN BAPTIST CASPARS, commonly called LELY's BAPTIST, was born at Antwerp^ and brought up in the fchool of Thomas Willeborts Bojfaert, a difciple of Van Dyck ; coming over into England in the time of the civil wars, Major Gene- ral Lambert took him into his fervice ; and upon the happy re- floration of King Charles II. Sir Peter Lely being received for his Majefty's principal painter, he employed Baptiji to paint his poftures, which he performed very well ; after his death, he did the like for Mr. Riley^ and afterwards for Sir Godfrey Kneller. This Baptiji was a great judge of painting, and hkewife emi- nent for his defigns for tapeftry, having been an admirable draftfman in the academy. He died in London about forty years ago, and lies buried at St. yames's. JOHN BAPTIST MONNOYER, commonly ftiled the flower painter, was b:>rn at LiJIe in Flanders, and brought up at Jntwerp. His bufinefs there was hifliory painting ; but he after- wards returned to LiJIe, and applyed himfelf to flowers, wherein he fucceedcd to admiration. Monfieur le Brun having under- taken the painting o{ Ferfailles^ employed Baptiji to do the flow- er part, wherein he ilaewed his excellence, as is yet to be (eea in that palace. His grace the Duke of Alontague being embaflador in France, and obferving the curioufnefs of this painter's works, invited him over to England, and employed him in conjunction with Meflieurs Ronjfcau and La Force, to adorn his magnificent houfe at Bloomsbury, where a great variety of flowers and fruit of this mafler are to be feen, and thofe the belt of his performance. There are alfo feveral other pieces of his at the Lord Car" lijleh, the Lo.d Burlington^?,, and other perfons of quality ; but the mofl: curious of all is the looking-glafs at Kenjingion-houk, which he painted for the late Queen Mary. They are alfo of an ordonnance very beautiful and furprizing, bearing a great price fuitab'e to their worth. His befl perform- ances were owned to be in England. He died in England about thirty-fix vears of age, and lies buried in St. "James's.

Firft a quantity of pure Gold, is melted and form'd into an ingot ; this by forging is reduc'd to a plate about the thicknefs of a fheet of paper, and this plate is after- wards cut into little pieces about an inch fquare, and laid in the firft and fmalleft mould to begin to ftretch them. From what Pliny relates, we have no room to doubt but that the ancients, efpecially the Romans, had the fame method of Beating Gold that we have, though it fhould fcem they did not carry it to the fame height. If it be as Pliny relates, that they only made five hundred leaves four fingers fquare of an ounce of Gold; though he fays they could make more. The modern Gold Beaters do make Gc/r/ of divers thicknefles; but there are fome fo fine, that a thoufand of them don't weigh above four or five drams. The thickeft are us'd for gilding on iron and other metals, and the thinneft for wood. See GILDING. This Gold is beaten on a block of marble, commonly call'd black 7narhle, of about four foot fquare, and ufually rais'd three foot high ; thefe plates are beaten with three hammers of diffe- rent fizes, of well polifli'd iron, fomething in the form of mal- lets. The firft which weighs three or four pounds, ferves to chafe or drive; the fecond eleven or twelve pounds, which is to clofe ; and the third which weighs fourteen or fifteen pounds, to ftretch and finifli. Like wife four forts of moulds of different fizes are us'd. Thefe pieces of an incji fquare, are put into the firft or fmalleft mould which is made of vellum, confifting of forty or fifty leaves, and .after they have hammer'd a while thus with the fmalleft ham- mer, they cut each of them into four, and put them into the fecond mould of vellum, which confifts of tviro leaves, to be ex- tended farther. Then they are taken out again, and cut into four, and put into the third mould, which is made of bullock's gut, well fcour'd and prepar'd, and confifting of five hundred leaves, and beaten ; then they are taken out and divided into four again, and laid in the laft and finifhing mould, which is alfo of bullock's gut, and containing five hundred leaves ; and there they are beaten to the degree of thinnefs rcquir'd. The leaves being thus finifh'd, are taken out of the mould and difpos'd in little paper books prepar'd with r^d hoUy fc the GqU BEN Gold not to ftick to ; each book ufually containing twenty five leaves. Thefe books are of two fizes, twenty five leaves of the fmalleft, of which weigh but five or fix grains j and twenty five of the largeft, nine or ten grains. Gold is beaten more or lefs, according to the quality or kind of the work it is defign'd for ; that which is for the ufe of Gold vire-drawers to gild their ingots withal, is left much thicker than that for gilding picture frames, l5^£.

Heavenly Beauty has been reprefented by an exceeding fine woman, naked, Handing upright, with her hand reaching the clouds and encompafled with rays, holding in one hand a lily, and in the other a celeftial globe.

Lamp BLACK, ? is the Smoh of rofin, prepar'd by me'ting Smoh BLACK, 5 and purifying the ro/in in iron vefTels, then fetting fire to it under a chimney or other place made for the purpofe, and lin'd at the top with fheep skins or thick linen cloth, to receive the vapour or Smole which is the B/acJ^ ; in this manner they prepare vafl quantities of it at Pan's. This B/aci may alfo be made by the Imrningof Lamps, having many wicks, covered with a very large top at a due diftance, to receive the Smoke, which continually flicking upon the top, pro- duces this Black colour ; the top of this L/imp may be taken off every half hour, and the Black fwept off it ; then the wicks being fnuffed, and the cover or top being put on again, repeat this till you have what quantity of colour you defire, or till all the oil is burnt out ; this Black is of excellent ufe for Black varnij}}. A quart of oil worth about fix or eight pence will make (as fome fay) Black enough to do a large cabinet. In England it is ufually prepared from the refinous parts of woods, burnt under a kind of tent, which receives it ; it is us'd on various occafions, particularly in printers ink ; for which it is mixt with oils of turpentine and linfeed, all boil'd together. This is to be minded, that this Black takes fire very readily, and when on fire, is very difficult to be extinguifli'd ; the heft method of putting it out is with wet linen, hay or ftraw, for water alone wont do it. A way to make Lamp Black better. Make a fire fliovel red hot, and lay the colour upon it, and when it has done fmoaking it is enough ; it may be us'd with gum water and ought not to be ground when us'd with oil. To make a finer Lamp Black than is ufually fold. It is made with lamps of oil, fomething being laid clofe over to receive the Smoke. German or Frankfort BLACK, is made of the lees of wine burnt, then wafh'd in water and ground in mills for that pur- pofe, together with ivory or peach ftones burnt. This Black makes the principal ingredient in the roUing-prefs printers ink. ■ It is moft generally brought from Ffankfort^ Mentz, or Straf- ' hi^f'g-, either in lumps or powder. That which is made in France, is not fo well efteem'd as that ' made in Germany, by reafon of the difference of the lees of wine ^ us'd in the one and the other ; though on the other hand fome 5 prefer that made at Paris to that made at Frankfort. ' Foreign Lamp BLACK, is no other than a foot rais'd from I 1 the rofiny and fat parts ef fir-trees. » ■ E 3 It B L A It comes moftly from the northern countries, as Sweden and Norway ; 'tis a Block that is more generally us'd than any other^ Jjeeaure.of its plenty ami cheapnefs, and proves a very good Black for moft ufer ; 'tis of fo fine a body that if it be only tempered With linfecd o\iy it will ferveto work with on moft common occaficiis i without grindins; ; but being tfius us'd, it will require ^ long time to dry, unlefs feme drying oil be mixt with it; or which is better fome verdigreafe finely ground, this and the drying oil together, will make it dry in a little time. Some add alfooil of turpentine ; and without thefe it will not dry under a long time, for in the fubftance of the colour is con- tain'd a certain greafy fatnefs, which is an enemy to drying. In order to remedy which, burn it in the fire till it be red hot, and ceafe to fmoke, which will confume that fatnefs, and then it will dry much fooner ; but when it is burnt it muft of neceflity be ground in oil, for elfe it will not work fine ; for fire is of that nature, that it is apt to harden moft bodies that pafs through it. See the article BURNING of COLOURS. This colour is ufually brought over to us in fmall boxes, and barrels of deal of feveral fizes. There is a BLACK made of willow charcoal, which if ground very fine, does in oil make a very good Black ; but not being fo eafy to be gotten as the Lamp Blacky 'tis feldom us'd. To make a BLACK, frofn Sheeps feet. Take Sbeeps bones, calcine them in an oven, or in a crucible in a furnace, and quench them in a wet cloth ; they muft be ground in water be^ fore any gum is put to them. This Black will mix with lake and umber for carnation in miniature or water painting. To dye wood. Horns and bones BLACK. DlfTolve vitriol in vinegar or fpirit of wine, and infufe them in it. Another way. Take litharge and quick lime of earth two pound, mix them with a fufficient quanticy of water and put in the bones, and ftir with a ftick till , they boil a-pace ; then take it oft' the fire, and ftir till it is -cold, .and the bones will be very Black. Spanijh BLACK is fo call'd, becaufe.firft invented by the Spaniards^ and moft of it brought from them, is no other than | burnt cork, us'd in various works, particularly among painters Earth BLACK, is a kind of coal found in the ground, which being weD pounded is us'd by painters in frefco. There is alfo a kind of BLACK, made of filver and lead, us'd to fill up the cavities and ftrokes of things engraven. ^hACK for painting or Jiaining.glafs. Take fcales of iroa from the fmith's anvil, grind them for three hours on a fhallow, copper or brafs plate (fuch as fpe9tacle,,f borax, half a pound of litharge of filver, and a quarter of a pound of litharge of gold, and half a pound of verdegreafe ; beat thefe together and put them into the kettle, and when the dye is warm, throw in fifteen pound of lockfmith's filings, ten pound of gum, and ten pound of copperas, and let thefe ingredients Hand to fettle eight days, llirhng it, as occafion requires; and after this you may dye with it, firft putting in a pint of brandy* A receipt to make a dye good. When it fhall happen that the dye begins to work off, you ought to confider what time of the month it was made, and what time work'd ; then put three pailfuls of water into a kettle, and add to it two ounces of bo- rax, half a pound of agaric, and a quarter of a pound of litharge i mf filver-, four ounces of madder^ half a pint of brandy, and a quarter B L A [quarter of a pound of verdegreafe ; boil thefe all together for an [hour, and then put them into the dye, and let it ftand to fettle )r a fortnight, ftirring it often. Then make a liquor of two pound oli ftnna leaves, two pound iof gentian^ one pound of agaric^ two pomegranate (hells, boil " them together for two hours, and then pour them into the dye ; when this has been done the dye will remain good for a hundred years ; and the longer you dye with it, it will yield the finer Black colour ; but then particular care muft be taken that no foot get into it, for that will fpoil it paft all help. But if any greafe or tallow happens to fall into the dye, let it cool and take it clean out, and if you cannot fee it, make the ladle red hot and ftir the dye about, and that will confume or burn up any greafmefs ; alfo fill two or three canvas bags with bran, and hang them in the dye while it is hot, and let it con- tinue two or three hours, then take out the bags, and cover the dye with brown paper; and that will attract all the greall* nefs of it. But when the dye begins to decay, whenever you dye, you muft ftrengthen and refrefh it in the morning with fix pound of gum f iix pound o{ copperas y four pound of filings, and a quar- ter of a pail of lye, then dye with it three days, fix pound of Sili at a time. When the Silk is dy'd it muft be boil'd, and galled as fol- lows: To every pound of Silk take twelve ounces of galls, and boil them two hours, then wring the Silki and lay it in the liquor for two nights and a day. y/ BLACK dye for re-dying hats or any thing that has lojl its Black colour. Take half a pound of hlueProvence wood, boil it in a pint of ftrong beer, till half of it be confumed ; then add half a pound of vitriol^ and an ounce of verdegreafe, then take out the wood, and put in a quarter of an ounce of gutn tragacanth i let it ftand, and when you have occafion to ufe it, dye a little brufti in it, and fo ftreak it over the Hat wool or filk, and it will give a fine lafting Black. BLACKNESS, is the quality of a Black body or a colour arlfing from fuch a texture, and fituation of the fuperficial parts of the body, as does as it were deaden or rather abforb the light, falling on it without reflecting any or very little of it to the eye. In which (tak Blacknefs ftands direflly oppos'd to whitenefs^ which confifts in f ich a texture of parts, as indifferently refleds all the rays thrown upon it, of what colour foever they be. Sir Ifaac Newton has Ihewn in his optic ks, that for the pro- du^ion of Black cglours, the corpufcles muft be lefs than thofe 2 ' which B L A which inhibit any other colours j becaufe where the fizes of the coFTiponent particles are greater, there is too much light refledt- cd to conftitute this colour; but if there be a little lefs than is requifite to refledt the white, and the very faint blue of the firft order, they will refled fo little light, as to appear intenfely Black; and yet may, perhaps, refle<5l it varioufly to and fro within them fo long, till it happen to be ftiflcd and lofl ; by which means they will appear Blacky in all pofitions of the eye, without any tranfparency. And from hence it appears why fire, and putrefaftion by di- viding the particles of fubflances, turn them Black ; why fmall quantities of Black fubftances impart their colour very freely, and intenfely to other fubftances to which they are apply'd ; the mi- nute particles of thefe by reafon of their very great number eafily cver-fpreading the grofs particles of others ; hence alfo appears why glafs ground very elaborately with fand on a copper plate till it be well polifh'd makes the fand, together with what by rubbing is worn ofFfrom the glafs and copper, become very Black ; and why Black fubftances do fooneft of all others become hot in the light of the fun, and burn (which effect may proceed partly from the multitude of refractions in a little room, and partly from the eafy commotion of fo very fmall particles ;) and alfo why Blacks are ufually a little inclin'd towards a bluifh colour ; for that they are fo, mav be feen by illuminating white paper by light refleding from Black fubftances, where the paper will ufually appear of a bluifh white; and the reafon is, that Black borders on the obfcure blue of the firft order of colours, and therefore refledts more rays of that colour than of any other. It is neceflary alfo to the production of Blacknefs in any bodies, that the rays be ftopp'd, retain'd and loft in them ; and thefe conceive heat (by means of a burning glafs, ^c.) more eafily than other bodies; becaufe the light that falls upon them is not reflected outwards, but enters the bodies, and is often reflected and refradted in them, till it be ftifled and loft. See LIGHT and COLOUR. Ohfervations on BLACK Colours. Lamp Black, ~( is the moft us'd, becaufe it istheeafieft to be Printer s Black, Chad, and is good in wafhing. But you muft never put Black upon other colours, to darken them, for it will make them diity, nor fhadow with Black, unlefs it be Spanijh hroxvn, when you would colour an old man's gown, which ought to be done of a fad colour ; all other colours fhadowed with Black look dirtily, not bright, fair or beauti- ful. Ivory B L E Ivory Blacky is the deepeft Black that is, and is thu<; made .; take Ivory in pieces, put it into a furnace till it be thoroughly burnt, then take it out and let it cool j pare off the outixde and take the blackeft in the middle. BLANCHING in Coinings is the preparation, that is given the pieces before they are ftruck, to give them the luftre and brillant. The ancient method of Blanching was by firft heating the pieces, and then putting them into a large veflel of common water, and fome ounces of aquafortis ; but in different propor- tions for gold and^ filver. This method is now difus'd, partly by reafon of its expenfive- nefs, and partly becaufe it diminifties the weight of the metal. Blanching^ as it is now pra£lls'd, is perform'd by heating the pieces on a kind of peel with a wood fire, in the manner of a reverberatory ; fo that the flame pafTes over the peel. The pieces having been fufficiently heated and cool'd again, are put fucceflively to boil on two other peels of copper, in which zxe aqua fortis, common fait and tartar oi Montpelier ; after they have been weil draid'd of this firft water in a copper fieve, fand and fre'h water is throvi^n over them, and when they are dry thev are well rubb'd. BLEACHING, c is the art or method of whitening linens, BLANCHING, S fluffs, filks, iffc and is as follows. For Bleaching fine linens. Wiien they come from the loom, and while they are yet raw, they are to be fteep'd a day in clear water, wafh'd out and clear'd of their fiith, and then thrown into the buckmg tub, fill'd with a cold lixivium or lye. When thefe are taken out of the lie, they are to be wafh'd in fair water, then fpread in a meadow, frequently watered from httle dikes or canals interfpers'd in the ground, by means of fcoops or a fort of long hollow fliovels, call'd by the Dutch, who invented them, gieter. After the linen has lain a certain time on the ground, and every thing has been repeated as before, it is to be pafs'd thro* a new lie pour'd on hot, and again wafli'd in clear water, and laid a fecond time on the ground ; and then pafs'd thro' a foft gentle lie, to difpofe it to refume the foftnefs, which the other Iharper lies had taken from it, then wafti'd in clear water, foap'd with black foap, and that foap is to be wafh'd out again in clear water ; then it is to be fleep'd in cows milk, the cream having been firft skimm'd off, which finifhes the w^//i?«;«^ ; and fcowring gives it a foftnefs and makes it caft a little nap ; when it is taken out of the mill, it is wafh'd in clear water for the laft time. Vol. I, F After B L E After all this procefs, they give the linen its firft blue by paf- fing it through a water, wherein a little ftarch, pale, fmalt, and Dutch lapis have been Iteep'd. In the la ft place, the proper ftifFnefs and luftre is given with ftarch, pale, fmak and other gums, the quantity and quality of which may be adj\jfted according to occaiion. The whole procefs oi Bleaching is finifti'd in fine weather in a month's time ; in ill weather, it takes up fix weeks or more. To BLEACH coarfe linens, they are taken from the loom and laid in wooden frames, full of cold water, where they are fo beaten by wooden hammers work'd by a water-mill, as to be infenfibly wafh'd and purg'd from their filth ; then they are to be fpread upon the ground in order to receive the dew for eight days, which will take oft* more of the rav\mefs: then they are to be put into a kind of wooden tubs or pans, with hot lye pour'd over them. Having been thus lixiviated, they are again purg'd in the mill, then laid on the ground again for eight days more, then they are to be pafs'd through a fecond lye ; and all things repeated, till fuch time as they have acquir'd their juft degree q( whitenefs. BLEACHING woollen JJuffs. There are three manners of whitening woollen fluffs ; the firft is with water and foap, the fecond is with vapour of fulphur, the third with chalk, indigo and vapour of fulphur. For the firft, when the fluffs are come from the fulling mill, they are to be put into foap'd water, pretty hot, and work'd afrefti by force of arms over a bench, which finifhes the whiten- ing which the fulling mill had begun ; in the lafl place, they are to be wafh'd out in fair water and dried ; this is call'd the na- tural way of Bleachiyig. The fecond method is what Is commonly call'd Bleaching by X^x&fiower, thus ; the fluff" is firft wafh'd in river water, and then put to dry on poles, and when it is half dry, fpread out in a kind of flove wherein fulphur is burnt, the vapour of which diffufing itfelf, flicks by little and little over all the fluffs, and gives it a' fine whitening. The third method is thus ; after the fluffs have been wafti'd, they are to be thrown into cold water, impregnated with chalk and indigo, in which they are well agitated \ they are wafli'd afrefh in elder water, then half dried on poles, and then fpread in a flove to receive the vapour of the fulphur, which finifhes the Bleaching. This method of Bleaching is agreeable enough to the fight , yet is not efteem'd the beft method of Bleaching. This is to be remembred, that when a fluff" has once receiv'd- the fleam of fulphur, it ^\\\ fcarce receive any beautiful dye, ftxcept black and blue. BLEACHING B L O BLEACHING of SilL The SI/I: being yet raw, is put intd a linen bag, and thrown into a vefTel of boiling river water, la which foap has been diflblv'd, and thus boii'd for two or three hours; the bag being turn'd feveral times, taken out and beaten, then wafh'd out in cold water, and wrung out flightly, and thrown into a veffel of cold Water, mixt with foap and a littld indigo. The indigo gives it the bluifli caft that is obfervable in white Silh. When it has been taken out of the fecond veflel, it is wrung out, and all the water and foap fqueez'd out, fhook out to un- twift and feparate the threads, and hung up in the air in a kind of ftove made on purpofe, in whicli fulphur is burnt, the va- pour of which gives the laft degree of wbitenefs to the Silk. BLEACHING HAIR, is done by fpreading the hair to be bleach'd upon the grafs, after the fame manner as linen, after it has been firft wafh'd out in a lixivious water. This lye with the force of the fun and air brings the hair fd fo perfedt a whitenefs, that the moil experienc'd perfon may te deceiv'd therein ; there being fcarce any way of detecting the ar- tifice, but by boiling and drying it; which leaves the hair of the colour of a dead walnut tree leaf. There is alfo a method of dying hair with blfmuih, which renders white hair, which borders too much upon the yellow of a bright filver colour. This alfo may be prov'd by boiling; the bifmuth not being able to ftand it. BLINDNESS of mind, is reprefented in painting by a lady cloth'd in green, {landing in a meadow, full of various flowers^ her head inclin'd, and a mole by her fide. The mole is an emblem of Bliruhtefs : her head inclin'd towards fading flowers, lignifics worldlv delights, which allure and bufy the mind to no purpofe; for that whatever the flattering world promifes, yet all is but a clod of earth, cover'd not only under the falfe hope of fhort pleafures; but with many dangers all our days. M MICHAEL LE BLON ofFrandfort, us'd this mark; J-J^-^ he died in Amjicrdam in the year 1650. To dye an 0;f-BLOOD colour. Firft tinge the ftufF yelloW, with a quartern and a half of madder to a pound of woollen fluffs, alum them and work them till they are of as beautiful a colour, as you would have them, then rinfe them well out, and put into the kettle a tub of Hale urine, and boil it again, till they take the dye ; then roll the Huffs three or four times thro* it, and rinfe them very clean. Fa fi B L U ro dye SILK a BLOOD colour. Soak the 5//i as before di- rected, and for each pound of it take half a pound oi allum^ and a quarter of a pound of tartar, beat them fmall and boil them in the quantity of a pail full of prepar'd liquor for a quarter of an hour ; then put in the Silk and let it fteep for two hours ; then take it out, rinfe it and beat it on a block, and hang it up to dry. Then put four ounces of galls powder'd into the quantity of a pail of water, fet it on the fire, till it isjuft fo warm as you can bear your hand in it, then put in the Silk, and let it lie for two hours; then take it out and dry it. This being done, put a pound and half of hraftle in a linen bag, and put in with it fome good wheaten bran water into a kettle, boil them together, being clofe cover'd ; then take the kettle off the fire, and let it ftand a whole night; then add a quarter of an ounce of pot-ajhes, and boil it again for an hour ; then pour on as much river water, as the liquor. Then take out the bag of brofile, and put in the Silk after it has been a little -fcumm'd ; cover the caldron very clofe, and let it remain there half an hour; then v/ring it out and rinfe it very clean in river water ; wring it out again, and hang it out again, and let it dry, and if it be not enough dyed, boil the dye again, and put in the Silk once more and clean it with foap, as in the crimfon clye, and afterwards rinfe it in the river water, and you will have a beautiful red. BLUE is one of the primitive colours, otherwife call'd Azure. Painters Blue is made different, according to the different kinds of painting. In limning, frefco, and 7)iiniatiirc, they ufe indifferently ul- traynarine, blue opjes, and fynalt ; thefe are their natural Blues, excepting the laft, which is partly natural, and partly artificial. In oil and miniature they alfo ufe indigo prepared : fee IN- DIGO. As alfo a faftitious ULTRAMARINE, which fee. Enamellers and painters upon glafs have Blues proper to them- felves, each preparing them after their own manner. Turtifole BLUE is a Blue us'd in painting on wood, made of the feed of that plant. The way of preparing it is to boil four ounces of Turnfde in a pint and half of water, in which lime has been flack'd. Flanders BLUE is a colour bordering on green, and feldom us'd but in landskips. To write on paper or parchment with BLUE ink. Grind Blue vv'ith honey, then temper it with glair of eggs or gum water made of ifing-glafs. ^> 4 BLUING B L U BLUEING of metals, is perform'd by heating them In the fire till they afTume a Blue colour ; particularly pradis'd by gil- ders, who blue their metals before they apply the gold and filver leaf. To dye skins BLUE. Boil elder-berries or dwarf-elder, then fmear, and wafh the skins therewith, and wring them out ; then boil the berries as before in a diflblution of alum water, and wet the skins in the fame manner once or twice, dry them, and they will be very blue. Another way to dye skins BLUE. Steep the beft indigo in urine for a day, then boil it with alum, and it will be good ; or tem- per the indigo with red wine, and wafh the skins therewith. The Pruffian BLUE. This Blue is next to ultramarine for beauty, if it be ufed in oil ; tho' I am not certain whether it will hold fo well as the other, confidering it has not the body of ul- tramarine. This colour'd does not grind well in water ; becaufe there is fuch an oily quality in it, that it does not mix kindly with wa- ter, and at the beft will change, as it is now prepared in the common way. Attempts have been made to make of it a blue ink ; which indeed has held the colour for a month or two, but then turn'd to a muddy yellow. And when you put your pencil with gum water into a fhell of this Blue, you will find where the water fpreads, the Blue will change yellowifh, till the body of the Blue is well ftirred up. And after all that can be done with this colour in water, it will only ferve to fhade ultramarine with ; but in oil it will ferve very well for the prefent to fupply the place of ultratiiarine. BLUE BICE is a colour of a good brightnefs next to P ruf- fian Blue, and alfo a colour of a body, and will flow pretty well in the pencil; efpecially if it be well wafti'd, as is directed to be done of the whites and minium. Saunders BLUE is alfo of very good ufe, and may ferve as a (hade to ultramarine, or the blue bice, where the (hades are not required to be very deep; and is of it felf a pleafant Blue, to be laid between the lights and (hades of fuch a flower, as is of a mazarine Blue. A fine BLUE fro-m Mr. Boyle. Take the blue leaves of rue, and beat them a little in a ftone mortar, with a wooden peftle ; then put them in water, juice and all, for fourteen days or more, wafhing them every day till they are rotten ; and at laft beat them and the water together, till they become a pulp, snd let them dry in the fun, F 3 This B L U This will produce as good a Blue as indigo, and be much ibfter ; but in order to keep it a long time, when you beat it jhe laft time, add to it a little powder of gum Arabick ; of livhich you may put more or lefj^, as you would have it more free or tenacious in the workmg. This is a fine blue for fhading, has a good body, and runs warm in the pencil. INDIGO BLUE. This makes the flrongeft (hade for ^/w^-j of ^ny other, and is a foft warm colour, when it has been well ground and wafli'd, with gum water, by means of a ftone and inuller. It Is -made of what lightnefs you pleafe, by putting more gum water to it ; and by how much there is lefs, the darker it Will be. Before you ufe it upon a print, it will be proper to try it upon a Dutch tile, for it runs v/armly in the pencil, and fo perhaps may otherv/ife prove too ftrong for your defign, which is always ^o ht taken care of, when a flowing colour is to be laid over ^ dark (hade of a print ; which Oiade will much heighten its blacknefs, and even make it appear quite black, LACMUS or LITMUS BLUE. This is a beautiful blue and will run in a pen as free as ink. It is made of lacmus^ or 2S fome call it Liifnus, which may be had at the druggifts. But as this colour is never to be met with prcpar'd, I (ball here fct down the method of preparing it. Take an ounce of Lacmus^ and boil it in about a pint of fmall beer wort, till the colour is as ftrong as you would have it j then pour off the liquor into a gallipot, and let it cool for ufe ; it will foon become a jelly, and by degrees grow hard. But this colour is to be opened again, and made liquid by wa- ter, fo as to be us'd as ink ; and will be either paler or darker, as it is made thicker or thinner. This affords a bright colour, and has extraordinary effects; for it is not only a beautiful, but a holding colour. This colour if it be touch'd with aqua fortis^ immediately phanges to a fine crimfon, little inferior to carmine, and finks quite through the paper, fo as not to be got out. So that when this colour is us'd as blue, it is beft to preferve it from alalia forth, or fuch ftrcng acids. It is a good ll:iade for ultramarine^ or h'ue hice^ where the flrongefl fliades fhould not be extremely deep ; and for colour- ing of prints it is very good, as it is a tranfparent colour, and goes a great way. A tranjparent BLUE from Air. Boyle equal to ultramarine. This is a beautiful Blue, and the chief ingredient of which it ^s made, is the cycnui or blue (ornbottlc fower, whic|i abounds J almoft B L U almoft ill every corn field, and may eafily be had, during four of the fummer months ; and may be gathered by children about the skirts or verges of corn fields, without doing any damage to the corn. This flower has two blaes in it, one of a pale colour in the larger outward leaves, and the other of a deeper Blue that lies in the middle of the flower. Both thefe will do, being feparated from the buttons or cafes, in which they grow ; but the deep blue leaves in the middle produce by much the beft colour ; which may be obferv'd by rubbing the leaves while they are frefh, fo hard upon a piece of good writing paper, as to prefs out the juice, and it will yield an excellent colour, which will not fade, as has been found by the experience of two or three years. This part of the flower is therefore the principal and what may be depended upon j which fhould be pick'd from the reft of the flower leaves, the fame day, \i it may be, or the next, or as foon as poflibly can be. A good quantity of thefe middle leaves being procur'd, prefs out what juice you can from them, and add to it a little alum, and you will have a laftirvg,- tranfparent Blue., of as bright a ftaining colour as can be delired, fcarce inferior in beauty to ul- tramarine^ and is durable. As for the outward flower leaves which are paler, it is not certain that they will anfwer the end ; but upon fome trials be- ing made, that may alfo be known. Let the flowers be gathered about the beginning of Jioie^ or in "July or AuguJ}^ and fome may be found in Aiay j but the preparation of the colour by picking out the middle deep blue flower leaves, and prefling out the juice, muft be prefb'd out with all the expedition poffible, or they will lofe their perfections. It is very probable, that if the chives of thefe blue corn-bottle flowers were cur'd in the fame manner as faflron is, they would produce a much greater body of colour, from which a tinclure might be drawn with more eafe, than if prelTed raw or frefli from the field. In order to do this, fuch a ki!n fhould be prepar'd as is us'J for curing of fafFron, in which may be made a fmall charcoal fire, which will communicate an heat to the top of the kiln, which is to be covered with an hair cloth ; upon which fhould be laid four or five fheets of white paper, fuch as is us'd in curing of fafFron ; then a parcel of the picked flowers are to be laid on to the thicknefs of two or three inches, laying clofe and flat with a knife, and fprinkling with fome thin gum water ; then the cake of flowers is to be covered with two or three more fheets of paper and a board with a fmall weight laid on for a few minutes ; after F 4 which B L U which the board is to be taken off, and the cake of flowers to be turn'd upon the kiln, taking hold of all the papers with both hands ; and when it has been rightly plac'd, take off the upper papers, and fprinkle the cake again with fome thin gum water; and then fettling the cake of flowers again with a knife, let the papers be laid on again with the board and weight for a minute or two, and then let the papers be turn'd again and again, till the cake of flowers becomes united, and of the thicknefs of a cake of fafPron. In this operation, you will find the flowers to grow darker ^nd darker every time they are turned, till at length the cake •will look of a deep Blue tending to black. From whence a tincture may be eafily drawn. During this operation, great care muft be taken that the fire does not fcorch the flowers ; but that it be as conftant and gentle as may be, which will be a fure way to bring the flower cake to a good colour. But it will not be improper for any perfon, who fhall under- take the curing of this colour, to confult the methods of curing faffron, of which they may be inform'd, either by a treatife of the method of curing faffron, written by Dr. Dowglafs^ or another by Mr. Bradley in his monthly treatife of husbandry and gardening. If it fhould be objected, that it will be troublefome to make this BLUE COLOUR ; let it be confidered what pains and nicety there is in gathering and curing of faffron ; which is fometimes fold at thirty fhiilmgs per pound , and feldom comes up to three pounds per pound. But this Blue^ if it comes up to the colour of ultramarine^ will be worth four or five pounds per ounce, efpecially when it ftains fo well as this does. Therefore it would, in all probability, be worth the while to have a piece of ground on purpofe for this ufe, where nothing elfe but this cyaniis or corn-bottle fhould be fown ; and whereas this flov/er is faid to be plentiful enough in the fields between l^wickenham and Tedd'mgton in Middlejex^ fo there might eafily be feed enough procured for that purpofe in half an hour's time to fow an hundred acres. As to the manner of cultivating this plant, every knob or head of feed mull b^ opened before it is fown, for each head contains a great number of feeds ; as for the preparing of the ground to receive this feed, there need to be no more trouble and expence than common plowing requires; which being done, the feed is to be fown either at the latter end of Auguji^ which will come up foon enough to fland the winter, and bloffom ^arly the May following ; or elfe it may be fown at the end pf March, and it will begin flowering the June following. '"'"'- At B L U At either of thefe feafons, after the ground has been well plough'd, harrow it in with bufhes, and it will come up in a little time. As to the choice of this feed, it will be neceflary that it be gathered only in fuch fields, where you are fure there grows no xorn-bottles of any other colour but blue ; and then all the plants which rife from fuch feed, would produce Blue-y but if they fliould be gathered in fuch places where there are varieties of them, then various forts are to be expelled, as white, red, or purple, altho' we are fure we gather the feed from fuch as were truly of a blue fort ; for if there is a red flower of the fame tribe growing near it, the difference of the colour will be fo in- termix! between both, that the feed of both will bring a va- riety from the principal, depending on the colours of both. Obfervations on BLUE Colours. Blue-Bice, is the moll excellent blue next to ultramarine, and may ferve inftead of it. It is too good a colour to ufe upon all occafions, zndfmalt may be us'd inftead of it for more ordinary ufes, but it will not work fo well as Bice ; therefore when you defign to beftow fome coft and pains upon a piece, you may ufe Bice, otherwife you need not ufe any other than blue-verditer ; with which you may make a pretty good fliift in ordinary works, although you fliould have no other Blue. Indigo is a dark Blue, and principally us'd to fliadow upon other Blues. It makes a dark green, being mixt with yellow berries, to fhadow other greens with in the darkeft places. Blue Verditer. It is a very bright pleafant blue, and the ea- fieft to work with in water j it is fomewhat inclining to a green, and the blue which is moft of all us'd mix'd with yellow berries ; it makes a good green. The method of making a vat, and preparing hot fuds for dying linen and woollen BLUE. Have a vat made big enough to contain eight pails of water, wide at the top, and narrow at the bottom ; feafon it for a day and night with hot water, and afterwards wa(h it out with cold, then cut a four-fquare hole at about the height of twenty one inches, and fourteen broad ; and have a copper plate made of the fame thicknefs with the wood of the vat ; nail this upon the hole, placing the nails at the diftance of the breadth of two fingers one from the other ; the nails muft be fmall with broad heads to prevent its leaking ; then place an iron hoop at the top and another at the bottom of the copper. The hole muft be made about a hand's breadth from the bot- tom of the vat. When B L U When this has been done, plaifter or brick it about, either leaving or making a hole in the plaifter or brick-work, wider at the utmofl end (and a little) narrower at that which comes to the copper itfelf ^ the fhape of it being like an oven's mouth, that the wood be not injured, when the fire to heat the vat of fuds is put into this vacancy. Then for every half pound of indigo, you put in, in order to! blue linen or woollen, take in eight pails of water, and intoi: that fix handfuls of coarfe wheaten bran, fix or nine ounces of madder, a pound and half of pot afhes ; pour them all into at copper to make fuds, and when the liquor boils fo as to begin toi fweil and bubble up, throw in two or three quarts of cold wa-; ter, and rake out the fire from under the copper. i Then having ready lime, prepar'd as the tanners ufe it, plai-j fier the infide of the empty vat with a handful or two of it, and afterwards pour all the ingredients out of the kettle into it,; and cover it very clofe. ■ The day before you do this, you muft put your indigo to dif-i folve in a quart or three pints of water in a clean vefl'el of iron or brafs, adding half a handful of wheaten bran, and half a ladle full oi madder, and half an ounce of pot-afhes, and leave it al whole night over a coal fire ; but it muft not be fufFered to boil, or grow hotter, than you can bear your hand in it. i You muft alfo grind it with a peftle, till it becomes as foftasi pap, and is quite cleared of all roughnefs or harflmefs; whichl being done, it is fit to be put into the vat to the other ingre-i dients. Then ftir it about three or four times with a ftick ; then cover | it up clofe, and let it ftand to fettle tv/elve hours ; then take I off" the cover, and put in half a quarter of an ounce of quick fil-i ver, and ftir it about and cover it as before ; then let it ftand to fettle for fix hours ; after which, throw in a fmall ladle full of lime di This therefore being the firft colour they begin to refleft, i muft be that of the fineft and moft tranfparent skies, in which ; the vapours are not arriv'd to a groflhefs fufficient to refledt other colours. M. de la Hire, and before him Leonardo de Vinci obferves, that zx\y black body, view'd thro' a thin zf^/V^ one, gives the fenfation of blue ; and this he affigns as the reafon of the blue ■nefs of the sky; the immenfe depth whereof being wholly de- void of light, is view'd thro' the air, illuminated, and whiten- ed by the Sun. For the fame reafon, he adds, it is, that foot, mixt with a white, makes a blue ; for white bodies being always a little tranf- parent, and mixing themfelves with the black behind, give the perception of blue. From the fame principle, he accounts for the blueruf: of the veins on the furfade of the ski ■. tho' the blood they are fill'd. with be a deep red ; for he obferves, that red, unlefs viewed in :a ftrong clear light, appears a dark brown, bordering on black. Being then in a kind of obfcurity, in the veins it muft have the effeft of a black ; and this view'd through the membrane of the veins and the white skin, will produce the perception of bluenefs. B.

Blue bice and red lead are not fo fine, as they may be faid to hear a very good Body ; but thofe before mentioned may be ground fo fine, as to be like even oil itfelf ; and then they alfo may be faid to work well, fpreading fo fmooth, and covering the body of what you lay it upon fo intirely, as that no part will remain vifible, where the pencil hath gone, if the colour be work'd ftifF enough. Whereas on the contrary verditers, and fmalts, with all the grinding poflible to be given them, will never be well imbodied with the oil, nor work well. Indeed bice and red-lead will hardly grind to an oily finenefs, nor lie intirely fmooth in the working ; yet may be faid to bear an indifferent Body^ becaufe they will cover fuch work very well that they are laid upon. But fuch colours as are faid mt to bear a Body, will readily part with the oil, when laid on the work : fo that when the colour (hall be laid on a piece of work, there will be a fepara- tion, the colour in fome parts, and the clear oil in others j ex- cept they are tempered extraordinary thick. EDWARD du BOIS was a hiftory and landskip painter,!' but chiefly the latter, born at Antwerp. He was difciple to one Croenwegen a landskip painter ; likewife who refided many years in England^ and had been fome time in Italy. Du Bois alfo j travelled to lialy, where he continued eight years, during all which time he ftudied the antiques, and painted after the Ita- lian gufto jointly with his brother now living here. He worked fome time at Paris, and in his way to Italy, did feveral pieces for Charles Emanuel Duke of Savoy. Soon after j his return to Holland^ he came to England, and died in London about thirty three years ago, being feventy feven years old. He h'es buried in St. Giles's church.

This colour is not to be made without a great deal of pre- caution. To fucceed well, you muft have in the furnace a pot fill'd with forty pound of good cryllal frit, carefully sk.imm*d, boil'd and purified, without any manganezc. Then you muft have twelve ounces of the powder of fmall leaves of copper thrice calcin'd, as directed in the article COP- PER. And half an ounce of zaffer in powder, prepar'd as direded in the article ZAFFER. Mix thefe powders together, and put them at four times into the pot, that they may the better mix with the glafs, llirring them well each time of putting in the powder, for fear it fhould fwell too much and run over. After the whole has been incorporated, well mix'd and pretty well fettled for two hours, try if the colour is deep enough, if fo, let it reft, though the fea green or sky colour feems at firff: greenifh, you need not be concern'd at it ; for the fait in the glafs will confume all that greennefs, and change it Into blue. After the metal has ftood at reft for twenty four hours, It may be wrought, and you'll have the colour deeper or lighter, according to the quantity of powder you have put into it. There is no other rule for that but the fancy of the work- man, for which reafon it cannot be afcertained ; befides, the matter that is us'd for tinging glafs, makes it have fome more colour, fome lefs, which proceeds from the preparatioa of it.

BORAX is a mineral fait, us'd in foldering^ braz'Dig^ and caji'ing gold and other metals. Borax is of two kinds, natural and artificial ; the natural is alfo call'd crude, the artificial is that which is purified and refin'd. The natural Borax is a mineral fait of the common form, dug out of the earth in feveral parts oi Perfia ; and is found alfo at the bottom of a torrent, running in the mountains of Pur- beth^ near the frontiers of White Tartary. When it is taken up it is expos'd to the air, where it acquires a kind of reddifh fat, i which ferves to feed it, and prevent its calcining. When it is in its perfe£iion, it is fent to Amadahat in the ter- ritories of the great Mogul ^ where the European merchants buy it. There is another kind of artificial Borax^ drier and of a grey- ii(h colour, like Englijh copperas^ only differing from the former I by its being longer expos'd to the air. The Venetians were the firft who found out the art of pre- I paring artificial Borax, or rather of purifying the natural. The 'method of doing it is by difFjlving it in water, then filtrating iand cryftallizing it; ufing for that purpofe matches of cotton,, about which the Borax cryflaliizes, like fugar candy and verde- greafe on wood. The Dutchy after they have refined it, reduce it mto little fpieces, like tagged points, and 'tis thus 'tis commonly ufed. Borax refined, either after the Venetian or Dutch manner, ifhould be clear and tranfparent, almoft infipid to the tafte; and above all, care muft be taken that it have no mixture of EngUJh alum.

Thus we havoi Brazil of Fernanibouc, Brafil of 'japan, of Ltanonj, of Si. Mart iha ; and laftly Brafilette^ brought from the Antilles^ , t .; The Brazil-tree commonly grows in dry, barren places, an4E m the middle of rgcks i li is very thick and large, and ufually^,. crooked BRA crooked and knotty. Its flowers, which are of a beautiful red, exhale a very agreeable fcent, good for comforting and ftreng- thening the brain. Though the tree be very thick, it is covered with fo thick a bark, that when the favages have taken it oft' the wood, a trunk, which was before the thicknefs of a man, is fcarce equal to that of his leg. BrafJ wood is very heavy, dry, crackles much in the fire, and fcarce raifes any fmoke, by reafon of its extreme drynefs. None of the feveral kinds have any pith, except that of Ja* pan. That of Fernambouc is efteem'd the befl. It muft be chofen in thick pieces, clofe, found without any bark j and fuch as upon being fplit from pale, becomes reddifh; and being chewed, has a fugary tafte. It is much us'd in dying, where it ferves for a red colour, but it gives but a fpurious colour, and eafily evaporates and fades ; nor is the wood to be us'd without alum and tartar. From the Brazil of Fernambouc is drawn a kind of Carmine by means of acids. There is alfo a liquid lacca made of it for painting in minia' ture. To make LAKE or TinSfure of BRAZILE. The Brazile meant here is that which the dyers make ufe of. Take of the finell that comes from Ferna7nbouck^ that being the beft. The way of extrafting this tindure is the fame as that from Kerfiies (fee KERMES) and may be effeded two ways, either with the menftruum fiifl prefcrib'd, or with ftrong waters; only obferve not to put fo much alum to each ounce of Brazile as to the berries ; for that tindiure is deeper than this from Brazile^ and confequently requires more fcufF; therefore ufe only in this as much as you think reafonable, experience will be the beft guide. Take notice too, that when you do it by the firfl menjiruum^ there is a greater quantity required of Brazile than was pre- fcrib'd of Kermes-berries^ to each pound of {hearings. In everv thing elfe follow the former diredlions, and you'll have a fine colour or lake lefs chargeable, and altogether as good as the tincture of Kermes^ for painting. BRASS, or as the French call it, yellotv copper, is a factitious metal made of copper and lapis calamiJiaris. The method of preparing ii; is as follows. The lapis having been calcin'd, and ground fine as flour, is mix'd with ground charcoal ; and incorporated, by means of v/ater, into a mafs : this being done, about feven pounds of the lapis calami^iaris is put into a melting-pot that will contain about a gallon ; and over that about five pounds of copper \ this pot is let dov/n into G 4. a wind- BRA a wind-furnace eight foot deep, where it remains for eleven hours, in which time it is converted into brafs. This metal then is call either into plates or lumps ; forty five pounds of crude lapis calammaris or calamine, will produce thirty pounds when calcin'd or burnt. ' iVjetimes brafs-Jhruff is us'd inftead of copper ; but that is noi. always to be procur'd in quantities fufficient, it being no other than a coUedion of old brafs. Pure brafs is not malleable, unlefs when it is hot ; for when it is cold, it will break. And after it has been melted twice, it will be no longer in a condition to bear the hammer at all; but in order to render it capable of being wrought, they put feven pounds of lead to a hundred pounds of brafs, which renders it more foft and pliable. The beft proportion for gun-metal for cafting great guns is faid to be a thoufand pounds of copper^ nine hundred pounds of //«, and fix hundred pounds of brafs in eleven or twelve thou-* fand weight of metal. The bell: brafs guns are made of malleable metal, not of pure copper and calamine alone j but coarfer metals are us'd to make it run clofer and founder, as lead and pot-metal, which laft is made of brafs and lead ; twenty pound of lead is ufually put into a hundred pounds of pot metal. Corinthian BRASS has been famous in antiquity, and is a mixture of gold, filver, and copper. L. Mummius having fack'd and burnt the city of Corinthy 146 years before our Saviour's time, there being there a valt number of ftatue?, images, vefTels, i^c. of gold, filver, and copper, all thefe melted and run toge- her by means of the violence of the conflagration ; and this mix-» ure was the compofition call'd Corinthian brafs. Thofe who peak of it accurately, diftinguifli it into three kinds ; in the firft, gold is the prevailing metal ; in the fecond, filver ; in the third, gold, filver, and copper are equally blended. To OTiJi^i? BRASS. Melt llx pounds of copper with two pounds of lapis calaminaris in powder for the fpace of an hour, and then put it out. To cleanfe BRASS. Take aqua fortis and water., of each a like quantity ; Ibake them together, and with a woollen rag dipt therein, rub it over ; then prefentiy rub it with an oily cloth: laftly, with a dry woollen cloth, dipt in lapis calamina- ris, and it will be as clrar and bright as when new. To purge BRASS. It is cleanfed or purged by cafting into it while it is melted, broken glafs, tartar, fal armoniack and fak petre, each of them by turns, a littk and a littk. To calcine BRx'\SS, caWd Orpello or Tiemclante, making a furious fen-green 6r sky-colour. Take thin Brafs, cut it into filial! BRA fmall pieces, put it into a crucible covered and luted at top ; fet it in a fierce fire, where let it ftand four day^ in a great (but not meltinEi) fire, for if it melt, your labour is loft. In four days time it will be very well calcin'd; then powder'd as fine as you poiSbly can, fearfe it, and the powder will be black ; fpread this on tiles, and keep a leer on burning coals for four days, near to the round hole ; take away the afhes that fall upon it, powder and fearfe it again, and then keep it clofe ftopt for ufe. To know if it be well calcin'd, put it into ghfs, and if it fwells, 'tis right ; if not, it is not well calcin'd, or elfe it is over burnt, and if (o^ it will not give a good colour. To calcine BRASS another way, to make o tranjparent RED. Cut your thin pieces of brafs fmaU, and put it into a melting pot. with layers of powder of brimjione, and metal as in copper. Set it firft on kindled coals, then put it into a ftrong fire in the furnace to calcine for twenty four hours ; then beat it to a fine powder, and fearfe it ; put it covered into the furnace on earthen tiles for twelve days, to reverberate ; fo powder, grind, and keep it for ufe. Befides a red, it contributes principally to the making a yel- low and chalcedony. A RED colour from BRASS. Put fmall pieces of it into the arches of the furnace, and let them remam there clofe till they are well calcin'd ; but in fuch a fire, that they may not melt; and when they are well calcin'd, powder the brafs, and the powder will be red, and excellent in many ufes for colouring \ Brafs thrice calcin'd is likewife very excellent. 1 To calcine BRASS thrice. Put this into the Avr, or into the furnello df the furnace, near the occhio , into pans baked or earthen tks; calcine it for four days, and you will have a black powder flicking together; pound it fine, and fearfe it ; then cal^ cine it again as before, but a day longer, and then it will not flick together, and will be of a rujjet colour ; and do fo the third time, but take care that it be not calcin'd either too much or too littb, for then it will not give a good colour. To know if it be well calcin'd, put it to purified metal, and it Will make it boil and fwell ; and if it does not, it is cither too (much or too little. This makes a curious jea-green, and an emerald- green., a /«r- \qu.ois or sky colour, and other varieties, BRASS to tinge of a gold colour. Diflilve burnt brafs in aqua fortis (made of vitriol, falt-petre, alum, verdigreafe and vermAlion) and then reduce it again, and it will be much of a gcid colour. To make BRASS thorough white. Heat brafs red hot, and quench it in water diftill'd from fal armoniack and egg (heUs ground together, and it wiU be very white. Ano^ \i iD "t* B R O Another way. Calcine eggfhells in a crucible, and tcmpci^ P» them with the whites of eggs ; let it Hand fo three weeks 3 heat the brafs red hot, and put this upon it. The way to colour BRASS white. Diflblve two penny weight of filver in aqua fortis, fetting it to the fire in a veflel till the filver turn to water ; to which add as much powder of white iariar as may drink up all the water, make it into balls, witlv which rub any brafs, and it will be as white as filver. BRAZING is the foldering or joining two pieces of iron, ^r.- by means of thin plates of brafs, melted between the two pieces"^ to be joined. If the work be very fine, as when the two leaves of broken faws are to be brazed or join'd together again, it is covered with' powdered Borax moiftened with water, that may incorporate ■with the hrajs-dujl^ which is added to it, and the piece is ex- pos'd to the fire, without touching the coals, till the brafs be obferv'd to run. But to braze with a ftill greater degree of delicacy, a folder is made of brafs with a tenth part of tin ; or another, one third brafs and two thirds filver ; or borax and rofin. But in all thefe manners of brazing, care muft be taken that the pieces be join'd clofe throughout ; the folder only holding in thofe places which touch. 1" -|-j HANS BRESANK engrav'd the ftories of the New l vi| ■ Teftament, and in the year 161 9, the twelve Apo- •* — ■— ^ flies, our Saviour, and St. Paul.

Then take out the flowers, and put the lye into a glaz'd earthen veflel to boil, adding thereto as much roch-alujn as it can well dilTclve; then take it ofF, and putting it into a large veflel, mix it with fair water, fo the yellow will feparate and defcend to the bottom 5 let it reft there a little, and after- 3 wards me B R O /^rds decant the water off gently, and fo put in more frefh to ; again and again, until the water has drawn off all the y^?// and lurn from the Uxivlum^ and it becomes clear. Thus the colour will be very well cleans'd of the fait and ,w, and remain exceeding fine and bright ; fpread it on pieces t white linen, and let it dry in the fhade on new baked tiles, nd you will have a moft admirable yellow for painting.

SpaniJ}} BROWN is a dark, dull red, of a horfe flefh colour- It is an earth, and is dug out of the ground ; but there is fome A it of a colour pleafant enough to the eye, confidering the Jeepnefs of it It is of great ufe among painters, being generally us'd as the firit and priming colour, that they lay on upon any kind of timber work in houfe painting, &c. it being a colour that is cheap and plentiful, and works well, if it be ground fine ; which 'may be done with much lefs labour than fome better colours re- quire. That which is of the deepeft colour is the beft, and that which is the freeft from ftones. Tho' the other forts do not give fo good a colour to the eye, vet they ferve as well as any others for a priming colour, for the feafoning of the wood in order to lay other colours on.

Pi^ I. The method of dying BROWNS. Take a fufficient quan tity of water, put it into the copper, and put of red-woot ground and nut galls bruis'd, of each twenty ounces ; boil then together, and enter twenty yards of broad-cloth, boiling it fo two hours and a half, and keep cooling it with a cooler, for feaii of fpotting ; then take it up and air it : then put in fixteen oun ces of copperas, and enter the cloth again, when it is almoi ready to boil again, and handle it, letting it boil half an hour and then cool it. If you would have the colour fadder, put ir more copperas. II. To dye a fad BROWN. Firft, infufe the cloth or ftuf to be dyed in a ftrong tinfture of hermoda£iyh \ then put faf-j fron and afhes xn a bag Jirattim fuper Jhatuniy upon which put water two parts, mixed with vinegar one part ; ftrain out the water and vinegar, being thoroughly hot, fifteen or fixteen times; In this lixiviate tinfture of fafFron, put the former matter to be dyed, letting it lie a night j then take it out, and without wring-| jng, hang it up to dry ; repeat this working the fecond andj third times, III. To dye a BROWN tawny^ or iron rujl colour. Make! a ftrong decoction of walnut-tree leaves in fair water ; then put] in the matter you would have dyed, and boil it fome hours with I the leaves in the faid liquor, and when it comes out, it will b«?j exadtly of a tawny brown colour. IV. To make the colour caWd the London BROWN. Firft dye twenty yards of cloth of a bright blue ; then take ftale, clear liquor raade of wheat bran a fufficient quantity, a quarter of a pound of ground logwood, and of alum two pound and a half; mix and boil the cloth two hours and a half, and then cool it ; afterwards take frefh liquor made of wheat bran and clear, to which put two pounds and a half of madder, and handle the cloth ; let it have a quick fire to a boiling, then cool it ; after which, take a fufficient quantity of fair water, half a pound of logwood, a quarter of a pound of brafil ground ; then let them boil wei!, adding fome urine; then enter the cloth, and handle it, and let it boil a quarter of an hotr ; cool it and wafli it well. V. To dye woollen a clove BROWN. Boil three pounds of alum^ and two pounds of tartar in a copper ; then put in the fluff, boil it two hours; then take it out, and put in together five pound of madder^ and a pint of wheat-bran, ftirring the liquor three quarters of an hour, till it is boiling hot 3 then draw off the wa- z ter,. B R O 3r, putting in frefli water, and put in a pound of galls and the loth, which boil for an hour ; then take it out again, and put hree pounds of copperas into the kettle, and then put in the ftufF gain, and ftir it about till it is fufficiently dyed ; then rinfe it. VI. Jnother clove BROWN. Heat fome water with clear ne flour, and for every pound of ftuft, put in two ounces of lufn^ one ounce of tartar in powder ; boil them together, then ut in the ftuft', and ftir it about for an hour; then cool and ifife it ; then ^leat fome fair water, and for every pound of ftuff", ike two ounces of brafile ; boil it for half an hour, then put le rinfed fluff" into it, and work it fo long, till it is fufficiently nged red ; then take it out, and add to the dye an ounce of ;/r/(j/; diflblve it very well, then work the ftuffs (o long in it ) you fhall judge proper ; then rinfe it out. VII. Another BROWN colour. Take as much water as will 3ver twenty eight pounds of wool, yarn, flannel or cloth; put into a copper, to which put nut-galls bruis'd fmall two pounds, ;d-wood ground half a pound; then put in the matter to be yed, let all boil together for three hours ; then take out the 'Oth and air it ; then put into the fame liquor four pounds of Dppcras, let it melt; then enter the wool, cloth, iffc. again, id boil it to deepen the colour to what degree you would ive it. VIII. Another London BROWN. To a fufficient quantity f water, put a pound of nut-galls bruis'd, red wood ground, ladder and fuftic of each half a pound ; boil all together for ihour; then put in your cloth or other matter to be dyed, id let it boil an hour alfo ; afterwards take it out and cool it ; len put in two pounds of copperas, and when it is melted, it in the cloth again, and fadden it. This will dye twenty Dund weight. IX. Another kind of BROWN. Put a pound of nut-galls uis'd fmall, two pounds and a half of red wood bruis'd to a fficient quantity of water ; let them boil for two hours ; enter venty yards of broad cloth, and fadden it at your pleafure. X. Another London BROWN. To a pound and a half of d-wood ground, put a fufficient quantity of water, into which Iter twenty yards of broad cloth ; boil all together for an hour ; ke it forth and cool it, and put into the liquor wood -foot a fficient quantity ; and let the copper boil till the wood is dif- Iv'd ; then put in the cloth, and boil it for an hour; take out le cloth and cool it ; put in copperas a fufficient quantity ; put the cloth again, and fadden it as ufual. XI. Another BROWN colour. Put two pounds of madder, id a pound and a half of nut galls bruis'd, and three quarters of pound of fuftickj into a fufficient quantity of water j let them boii'j. B R U boil, and then put in fifty pounds of wool, yarn, flannel or cloth; let it boil for two hours and a half; thtn cool it, and put in copperas two pounds, and boil to a fadnefs defign'd. XII. To dye a lofting and neat purple BROWN. Firft dye cloth (for flight fluffs will not bear the price of this dye) a blue, cither light or dark, according as you would have the colour ; then boil it firfl either with galls and madder, or with galls only ; and after that with copperas. When it has been well boil'd with madder, or with copperas and madder, or with galls alone, if it be perfectly finifti'd, it will not take any ftain from ivine, vinegar, or urine. On the contrary, all colours dyed with wood ; as for exam- ple, the red or the blue, in which braftle has been us'd, will take ftains from the weakeft acids, which will caufe in them a very vifible change. Indeed yellow wood is a fort of exception to this general rule, for its dye does not change fo foon. XIII. To dye barley Jlraw, &c. BROWN. Take a fuffi- cient quantity of lixivium, Indian wood ground, green Ihells of wallnuts, of each half a pound ; let the ftraw fteep four or five days in a gentle heat, and then take them out. XIV. To dye or Jlain wood of a walnut tree BROWN. Take the green fhells of wallnuts, dry them in the fun, and boil them in nut oil ; and rub the wood with this oil.

In the choice of brujhes and pencils obferve the following directions. For brujhes, obferve whether the briflles are fafl bound in the ftocks, and if the hair be ftrong and lye clofe together ; for if they do not lye clofe, but fprawl abroad, fuch will never work well ; and if they are not fafl bound in the flock, the briflles will come out when you are ufing them, and fpoil your work as may be feen where the loofe hairs of the brufh have lain up and down in the colours laid on, to the great difparagement of the work. To prevent this, if they are not faft bound, drive in fonn thin wooden wedges, between the thread with which they arc bound round, and this wiU render the brUlIes tight and fecure, WIRE BUG WIRE BRUSHES are of ufe for fcrubbing thofe fllver, copper, and brafs pieces which are to be gilded over, thereby perfedly to free them from any dirt, ruft, or filth which may adhere to them ; which not being taken off, would hinder the clofing of the gold with them. They are therefore us'd by gil- ders, filverfmiths, ^c. and are ufually fold by iron-mono-ers. A^liOr^Sor¥^ BRUYN. He ufed times. Charles le BRUN, was born ^t Patisy anno 1620. and he began his ftudies under Simon Foiieti and finiflied at Rome by the favour of Monfieur the Chancellor Sequier, who fent him thither with a confiderable penfion for three years ; the firft proofs of his abilities after he returned home, were the prize pieces he made two years fuccefsfully for the church of Notre Dame; and his performances foon afterwards in feveral of the fine houfes in France, gave fuch a luftre to his pencil, that the King (upon the recommendation of Monfieur Colbert) made him his chief painter, ennobled him, hortour'd him with the order of St. Mi- chael. He bad a genius lively, penetrating, and equal to every thing he undertook ; his invention was eafy, and his talent (ex- cepting in landfcapes only) univerfal. He was not indeed admired for his colouring, nor for his skill in the diftribution of his lights and fhadows ; but for a good gufto of defign, an excellent choice of attitudes, an agreeable management of his draperies, a beautiful and juft expreffion, and withal a ftri<3: obfervance of the decorum of his compofiti- ons, will command attention and admiration of the niceft judges. His capital works are the deling of the gallery, and grand ftair-cafe of Verfailles, and his five large pieces, containing the hiftory of Alexander the Great, the prints of which are alone enough to render his name famous to pofterity. He had the fu- perintendency of the manufactures at the Gobelines., and for fom.e years, governed all the Kings artificers. He died in France an- no 1690. atat. 70. B. S. fienifies Bartholomew Skenius, or Bononenfis fculptor. JOSEPH BUCKSHORN was a Dutch painter, born at the Hague, who came over to England about the year 1670. He was efpecially eminent for his copies after Sir Peter Lely, whofe manner he came fo near, that feveral heads of his have been taken by good judges for that great mafter's. He copied alfo Van Dyck, and the prefent Lord Rockingham has the pidure of the Earl of Strafford done by him after that great painter. He was Sir PiUr Lel/% drapery painter f^r ma- ny BUR ny years, and died in London at the age of thirty five, and lies buried in St. Martins Church. BUILDINGS, as TOWNS, CASTLES, RUINS, isc, are painted as follows, i. Thofe towns or cities which feem to be far off, muft have but little fliadowing or heightening, and fometimes none at all ; thefe, if they appear againll the sky, jiiuft be laid with Bice and a little purple, and fliaded faintly with a good blue. 2. Thofe which are fituated fomething farther diftant, muft be laid with blue and purple as aforefaid, and (haded with light blue, and heightened with white. 3. Thofe which appear at an ordinary diftance, muft be laid with vermilion and purple y and fhaded with a ftrong purple, fliaded with white. 4. Thofe which are near, muft be done with vermilion and white, and (haded with a ftrong vermilion, and brown oaker, mixt with white. STONE BUILDING [to paijit in miniature.] Do it with indigo, hijlre, and white, for the dead colouring or ground ; and then (hade with lefs of this laft, and more of the bijire and indigo, according to the colour you would have the (tones to be; you may, if you pleafe, add a little oker, both to begin with and to finifh. But to add ftill to its beauty, you (hould here and there, efpe- cially for ruins, make teints of blue and yellow ; the former of caker, and the latter of ultramarine, always mixing them with white, whether for the firft ground, provided they appear thro' what you lay upon them, or whether you ufe them at laft, fini(h- ing and blending them with the reft. WOODEN BUILDINGS, as they are of different kinds, they are left to difcretion j but the moft ufual way is to begin with a mixture of oaker, bijlre and white ; and hnifh without zvhite, or with but very little; and when the (hades require ftrengthen with hijire alone. For others, you may add fometimes vermilion, or fometimes green or black ; in a word, according to what you intend, you muft mix your colour, and ftnifh with ftippling, as for draperies and all the reft. BURNING of COLOURS. There are feveral colours that require burning; as fir(t la7np black, which is a colour of fo greafy a nature, that except it is burnt, it will require a long time to dry. The method of burning, or rather drying lamp-black, is as follows : put it into an iron ladle or a crucible, and fet it over a clear fire, letting it remain till it be red hot, or fo near it, that there is no manner gf fmoke arifes from it. Secondly, I I ^ BUR. Secondly, umber, which if it be intended for colour for art horfe, or to be a fhadow for gold, then burning fits it for that purpofe. In order to burn umber, you muft put it into the naked fire in large lumps, and not take it out till it is thoroughly red hot ; if you have a mind to be more curious, you may put it in a cru- cible, and then put it into the fire, till it be red hot} then take it out, and when it is cold, lay it up for ufe. Ivory alfo muft be burnt to make a black, thus : fill two cru- cibles with fliavlngs of ivory ; then clap their two mouths toge- ther, and bind them faft with an iron wire, and lute the joints clofe with clay, fait, and horfe-dung well beaten together ; then fet it in a fire, covering it all over with coals, and let it re- main in the fire, till you are fure the matter inclofed in the cru- cibles is thoroughly red hot ; then take it out of the fire, but do not open the crucibles, till they are perfectly cold ; for if you {hould open them while hot, the matter would turn to afhes ; and fo it will be, if the joints are not luted clofe ; for it is only the exclufion of all air, that prevents any matter whatever that*s burnt to a coal, from turning to a white afli, and preferves the blacknefs. BURNING GLASSES. A machine by which the fun's rays are collected into a point ; and by that means their force and efFefts heightened to that extreme degree, as to burn objects plac'd in them. They are of two kinds, either convex or concave ; the convex tranfmit the rays of light, and in their pafl'age refract or incline them towards its axis; having the property of Lens's, and a£ting according to the laws of refraction. See LENS and RE- FRACTION. The concave, which are the more ufual, are very improperly call'd Burning GlaJJes, in that they are ufually made of metal ; thefe refledt the rays of light, and in that rcilection, incline them to a point in their axes ; having the properties of mirrours^ and adting according to the laws of r'eflection. See MIRROUR and REFLECTION. Every concave mirrour or fpecidum, collects in rays difpersM thro' its whole concavity, after refiedtion into a point or focuiy and is therefore a burning mirrour. Hence, as the focus is there, where the rays are moft clofely contracted, if it be a fegment of a large fphere, its breadth muft not fubtend an arch above eighteen degrees ; if it be a fegment of a fmaller fphere, its breadth may be thirty degrees. M. Kircher is of opinion, that thofe Burning Mirrours, which do not in their breadth fubtend an arch of more than eighteen degrees, are the beft of all others. Vol. I, H As BUR As the furfacepf a mltrouryWhich is a fegment: of a lai^er fphere, rcc-ives more ravs than another of a Jefs ; it the breadth of each jiibtend an arch c»f eiohteen degree?, or even more or lefs, pro- vided it be equal, the efFedls of the larger mirrour will be greater than thofe of the IcfTer. And as the feats is contained between the fourth and fifth fjart of the diameter, rmrrcurs that are fegments of greater inheres will bum at a greater diftance, than thofe which arc fegments of a lefTer. And fince the burtj'wg deperKis upon the uniting or union of the rays on the concave, fpherical figure; it is not to be admired ar, ti'at even wooden mlrrcurs gilded, or fuch as are prepar'd of a'abafter, t^c. covered with golJ, nav even fuch as are made of paper, ar^d covered with ttraw, fhould be found to burn. Mr. Tfihirno jus's mirrour, the breadth of which is near three Leipf.ck ells, and its focus two ells diftant from it, was made of copper, and its fubftance not more than double the thicknefs of the back of a knife, according to the account in the a£la tru- d'ltorum, perform'd as follows : 1. It fee fire to green wood inftantaneouny, fo as not to be exiinguifh'd bv a ftrong; wind, 2. It boiFd water immediately, and eggs in it were rendered eatable prefently. 3. It caufed a mixture of tin and lead three inches thick to drop prefentlv ; and an iron or ftecl plate became red hot pre- fently, and a little while after burnt holes thro' it. 4. It rendred things not capable of melting foon red hot like iicn ; fuch zs^Jtoncs, bricks, 6iC. 5. It rendred Jlate, firft a white and then a black glafs. 6. It converted tiles into a yellow glafs, and (hells into a biack- ifh yellow one. 7. It melted a pumicc-Jione tlirown out of a volcano into a white glaCs. 8. It vitrified a piece of a crucIMe in eight minutes. 9. Ic quickly turii'd Bones into an opake glafs, and earth inta a black one. Dr. Harris and Dr. Dcfaguliers inform us, that they found the following effects perform'd by a Burning Glafs or AJirrour^ made of a compofition of //w, copper, and tin-glafs, in width forty fevcn irches j. ground to a fpbere of fevemv ^^-^^ inches radius. So that its focus was about thirty eight inches from the vertex. 1. It melted a fehtr fix-pence in 7" -j. 2. A King Gccrge the I's half-penny in 16', and made it run with a hole in 34. 3. It melted tin in 3", caft iron in i6"5 flate in 3", 4. It ?B U S 4. It calcin'd a fofllie fliilling in 7". 5. It vitrified a piece of Pompey's pillar at j^lexandrla \n the black part in 50", in the white in 54', copper o^r in S ; cal- cin'd bones in 4', and vitrified them in 33. 6. It melted an emerald into a fubftance like a turquols ftone j and diminifti'd I of the weight of a diamond that weighed four grains ; vitrified aibejlosy as it would do all other bodies, if they were kept long enough in the focus ; which when they are once vitrified, the mirror can go no further with them. BURNISHING is the art of fmoothing or polifhing a body by a violent rubbing it with any thing. Thus book-binders burn'ijh the edges of their books by rub- bing them with a dog's tooth. Gold and filver are burnifli'd with a wolfs toothy a dogs tooth, the bloody-Jlone^ tripoli, a piece of white wood and emery. Hence a Bumijher is a round polifli'd piece of fteel, ferving to fmooth, and give a luftre to metals. BUST 7 [in fculpture, 6rV.J a term us'd for the portrait or BUSTO 5 figure of a perfon in relievo ; (hewing only the head, flioulders and ftomach, the arms being lopp'd off, ufaally plac*d on a pedeftal or confule. M. Felibien obferves, that tho* in painting one may fay a fi- gure appears in Bujlo ; yet it is not properly call'd a Bujiy that word being confin'd to things in relievo. The Buft is the fame that the Latins calPd Herma^ frorti thd Greek Hermes., Mercury ; the image of that god being freqaently reprefented in this manner by the Athenians. BUST is alfo us'd, efpccially by the Italiansy for the trunk of an human body, from the neck to the hips. Menage derives it from the word bufque, a piece of wood, ivory, or whalebone, or the like, which women apply to their itomachs, to keep themfelves ftreight, which the Italians call bujio. BUSTLER was a Dutchman^ both a hiftory and face painter in the reign of King Charles \l. There is a good picture, partly performed by him, in Mr. Elfum\ pofieflion of the Tejn~ pUy which confifls of three boors playing together in different aftions by Mr. Bujiler^ a good land^klp behind by Mi .

Kill the butterfly, but take care not to injure the wings, but fpread them open in a flying manner as exadlly as may be j then take a piece of white paper, and with a fmall brufh or pencil, wafh a part of the paper with gum-water, a little thicker than ordinary j folet it dry leifurely j then lay the Butterfly on the paper, and when you have fixt it H z well. C A L We1!, cut av/ay &,e body clofe to the wings, and throw it away j (that the prefling of the body may not fqireeze out the intrails, and fpread and fmear the impreiHon) then lay the paper on a fniooth board, with the wings of the butterfly upwards, and on the fly another paper, and a fmooth trencher upon thatj and put the boards, paper, and wings all together into a linen fcrew-prefs', and fcrew it down Tery- hard, and let it ftand in it for an hour ; and then take off the butterfly's wings, and there ■will remain on the paper their perfect impreiTion in all their beautiful colours. But if you have not a fcrew-prefs, lay weights upon your up- permoft board, and it will come off very well. , The reafon of this is, that all the fine colours that appear on the wings of a butterfly, are a fort of fine feathers, or rather a pov^'der, which flicks fo fail to the gum, that when the gum iS dry, they leave the wing. After you have thus gotten the beautiful wing5, you may draW the body, i^fc. of the butterfly, and colour the drawing of it after the life. NICHOLAS BYER was a hiftory and face painter, born 2X,Drorithem. in Norway. He was much employed by the late Sir WiUiain Temple at his houfe at Sbene^ near Richmond, in Surrey^ where he died about forty fix or forty feven years ago. He was a painter of good hopes, but died young, the effe6t of an intemperate life. He lived with Sir William three or four years, during all which time, he was conftantly employed by hjm in one fort of painting or other, 'One thing is remarkable in him, and that is, that he was the firft man that was buried in '$>K.

It is dug out of mines, ufually in fmall pieces, having eyesj fometimes veins, of lead ufually ; tho' not always found in lead mines. It is generally dug in barren rocky ground ; its courfes run- ning ufually at iix a clock (as the miners phrafe it) /'. e, from eafi to weft, fometimes at nine and fometimes at twelve i or per- pendicular, which is accounted the beft. After it has been dug, it is wafh'd, or huddled (as they term it) in a running water, which carries off" the impurities and earthy parts, leaving the lead, calamine,, and other fparrv parts at the bottom ; then it is pat into a fievc, and fliakca well in water, and the lead that is mixt with it fmks to the tottom, the fparry parts afcend to the top, and the calamine remains in the middle.

CAMERA OBSCURA, i. e. a DARK CHAMBER, is a machine or apparatus, reprefenting an artificial eye ; whereon the images of external obje£ls are exhibited diftin6tly, and in their native colours, either invertedly or ere6t. The ufe of this machine is manifold ; it ferves to many good purpofes in explaining the nature of vifion j and hence it is that it is by feme call'd the artificial eye. It affbrJsvery diverting fpe£lacles, both by exhibiting images, perfectly like their objects, and each cloth'd with their native colours ; and by exprefHng at the fame time all their motions, which latter no art can imitate. The theory of the Camera Obfcura is contained in the fol- lowing propofition. If an objeft A B (figure r J radiate through a fmall aperture C, upon a white wall oppofite thereto, and the place of radia- tion behind the aperture b C a he dark ; the image of the ob- je£t will be painted on the wall in an inverted fituation. Demonjlration. For the aperture C being vzx'j fmall, the rays ifiuing from the point B will fall on b ; thofe from the points A and D will fall on a and d: wherefore fince the rays ilFuing from the feveral points are not confounded, when reflected from the wall, they will carry with them a certain fpecies <^ the objed-, and exhibit its appearance on the wall. But fince the rays A C and B C interfeft each other in the aperture, and the rays from the loweft parts fall on the higheft, the fituation of the objedl will of necefTity be inverted. Corollary. Since the angles at D and d are right, and the vertical ones at C are equal, B and b and A and a will be alfo equal ; confequently, if the wall whereon the objedt is delineated, bs parallel to it, c, ^ : A B : : ^ C : D C ; that is, the height of the image will be to the height of the objeft, as the di-. ftance of the object from the aperture, is to the diftance of the image from the fame. See the plate, figure i . ConfiruSlion of a CAMERA OBSCURA, wherein the ima- ges of external objeds fhall be reprefented diftindlly, and in their genuine colours, either in an inverted, or an ereft fituation. 1. Darken a chamber, one of whofe v/indows looks into a place fet with various objefls, leaving only one little aperture ppen in the window. 2. In this aperture fit a lens, either piano convex^ or convex pn both fides, to be a portion of a large fphere. 3. At GAM 3. At a due diftance, to be determln'd by experience, fpreaJ a paper or white cloth, unlefs theie be a white wall for the pm- pofe ; for on this, the images of the defired objeds will be de- lineated inverted ly. 4. If you would rather have them appear erecl, this may be done either by means of a concave kns, plac'd between tiic centre and the fjcus of the firft lens; or by receiving the image on a plane fpeculum., inclin'd to the horizon under an angle of 45° 5 or by means of two lens's included in a draw tube in- Itead of one. Note, that if the aperture don't exceed the bignefs of a pea, the objects will be reprefented, even tho' there be no lens at all. To render the images clear and diftin<3:, 'tis neceflary that the objeds be illumin'd by the fua's light; they will be llilt bvighter, if the fpedator firft flay a quarter of an hour in the dark. Care muft be likewife taken, that no light efcape through any chniks; and that the wall ben't too much illumm'd. Farther, the greater diiiance there is between the aperture and the wall, the larger and more diftinct will the images be ; but the rays becoming thus too much dilated, the brightnefs ot the image is weakened, till at length it becomes invifible. The conftruaion of a portable CAMERA OBSCURA. I. Provide a little cheft or box of dry wood, in the figure of a paralielopipedon, in breadth about ten inches, and its length two it^t or more, according to the different magnitude of the diameter of the lens.

CARBUNCLE is a very precious ftone, of which feveral ^uthois have written j but I don't know one who fays he has feen it. They attribute to this ftone the property of giving light in the dark like a burning coal, or a kindled lamp. Ludovlcus Verromannus reports, that the King of Pegu car- ried one about him of fuch bignefs, and fo great fplendor, that thofe w^ho faw that prince when it was dark, faw him fliining as if incircled with the funj but this author, as well as the reftj fays he never faw one. Pliny pretends, there are many forts of Carbuncles, fome jnale ones more hard and biighterj and others female more lan-= I guid. CAR guld. But this author is fo indiftindl and fo little afTur'd of It, that his teftimony cannot be taken for authentick. Yet among all thofe fpecies which he defcribes, thofe feem to approach the nearcft to carbuncles^ which he calls Lithlzontes and fandajlri. The firft difcovers ftrongly its fplendor at the fire or fun ; being in the {hade, it appears of a purplifli colour ; being ex- pos'd in the open and clear day, it fparkles as it were at the fun- beams, and hides as it were bright ftars within it. The fecond is curious, by reafon of golden fparkles appearing and glittering within like ftars, which are always feen acrofs it within fide, but never near the furface, imitating the Hyades by their number, difpofition, and order, This author fays laftly, that the Chaldaans held this laft ftone in great veneration, and us'd it in all their ceremonies. It is indeed very probable, that the Carbuncle is that ftone the antients have related to give light by night, like a flaming fire, and by day hke a twinkling ftar, which is now no more to be found. But whether the Carbuncle be a precious ftone, found in the bowels of the earth or not, the properties that thefe authors have given it, may be imitated by the help of art. And this may be done two ways, as follows. Take ten ounces of matter, prepar'd with faiurnus glorifcatus^ (fee SATURNUS, ^c. in S.) and natural cryftal reduced to an impalpable powder, as there directed ; add to this half an ounce of crocus Martis in fine powder prepared. (See CRO- CUS, &c.) Mix thefe powders well together, and put them into a good crucible, which cover and lute well ; then put it into a glafs houfe fire for three days, putting it nearer and nearer the ftrength of the fire by degrees. Then take out the crucible, and put the matter into a mar- ble mortar ; then pound and grind it very fmall, with its weight of fal gertimce^ and put it into another crucible, which cover and lute as before. Being dry, put it into the fame glafs houfe furnace, removing it nearer to the fire by little and little, and let it ttand for twenty four hours in a good fufion. Then take it out, and put it into the furnace to bake again, as you do glafs, where leave it twelve hours, that it may cool gently. When the crucible is cold, take it out of the furnace to bake again, then break it, and you'll find in it the matter tinged of a very fine carbuncle colour, which you may cut of what form you pleafe ; polifli it at the wheel, and it will be perfeft. CARBUNCULUS noae illumlnans, which is a ftone far more refplendem and fairer than the former, But CAR But this is not a ftone any where form'd by nature ; but may be made by art. But to imitate this fecond Carbuncle, or rather the beauty which authors attribute to it, do as follows. Take ten ounces of matter, prepar'd of natural cryJlaU and Jaturnus glorificatus^ and having reduced them to an impalpable powder, add to it an ounce of gold calcin'd (as will be fhewn in the articles CALCINE or GOLD) mix the whole well toge- ther, and put it into a good crucible, which muft not be above half full ; cover it and lute it well, let it dry ; then put it into a glafs houfe furnace for three days, bringing it by little and little nearer to the ftrongeft fire. After three days, take out the crucible, and put the matter into a marble mortar, which pound to an impalpable powder, to which add its weight of fal gemmee, alfo in fine powder, which mix well together, and fearce through a fine fieve, the better to incorporate. Put this powder into a new crucible, which you muft not fill ?tbove half way ; which cover, lute and dry as before : then put it into a glafs houfe furnace, bringing it nearer to the fire by little and little, where let it ftand ten hours. After this, take your crucible out of the furnace, and put it L'\to that where they fet their glafles to anneal ; let it ftand for ten or twelve hours; then take it Qut, and by breaking it, you V ill find the matter ting'd of a carbuncle colour, the moft lively and refplendent tliat can be made by this art j whereof you may make what fl:ones or works you pleafe. CARE. Though it commonly makes one old, yet fhe in paint ng is reprefented fo as to appear comely ; (lie is winged hold- ing two h jur glalTej, a cock at her heels, and the fun rifing from the ocean. Her handfomenefs denotes her taking time by the forelock, and ftopping all good things ; the wings denote quicknefs ; the glafles and fun Ihew that care and Tolitude is never ,weary. CARICAIURAES [in painting] as to make caricaturaes i» to exaggerate, the defeat?, and conceal the beauties in perfons faces ; hovv'ever preferring the refemblance. JOHN CARINGS was an Englifh landfcape painter, who lived the be:ter part of his time in Holland^ and drew many views of that country in a manner very neat and elaborate^ His pieces bore a great price in his life-time, but having little befides their neatnefs to recommend them, they have fince been lefsefteemed.

CARMINE, a red colour, very vivid, bordering fomewhat on the purple, us'd by painters in miniature ; and fometimes painters in oil, tho' rarely, by reafon of its great price. Carmine is the moft valuable produdt of the cochineal mejiique ; which is a fecuia or fediment, refiding at the bottom of the water, wherein cochineal^ conan, and antour has been fteep'd : fome add rocou^ but this gives carmine too much of the oval caft. That which is good is almoft in an impalpable powder. Some make Carmine with brazile wood, fernambouc^ and leaf gold beat in a mortar, and fteep'd in white wine vinegar ; the fcum arifing from this mixture, upon boiling, when dryed, makes Carmine \ but this kind is vaftiy inferior to the former. • Another Carmine, Steep a pound of brazile wood, oi fernam- bouc of the colour of gold, for three or four days in an earthen veflcl or pot of white wine vinegar; after having broken ic well in a mortar, boil it half an hour. Then pafs or ftrain it through a very courfe linen cloth, and fet it again upon the fire. Take another little pot of white wine vinegar, and in it fteep or temper eight ounces of alum. Put this alum (o tem- pered in the other liquor, and ftir it about well with a fpa- tula. The fcum or froth which arifes is the Carmine ; take it off as it rifes, and let it dry. The fame may be done with cochineal inftead of brazile. Another Carmine. Take three pints of fpring water, which has not pafled through leaden pipes j put it into a glaz'd earthea pot, and fet it on the fire. When it is ready to boil, put in half or a quarter of an ounce of the grain of cohan or dyers red, which the feather dyers ufe, reduc'd to a fine powder. Then boil it for about three quarters of an hour, or till the fourth part of the water be confum'd. Let the fire be a coal ftre. Then ftrain this water through a linen cloth into another well glaz'd velTel, and fet it on the fire till it begins to boil ; then put in an ounce of cochineal^ and a quarter of an ounce pf arnoitoj both reduc'd to powder apart i and let this liquor boii C A R. Isoil away to one half, or rather till it raifes a black fcam> and :, as very led ; for it takes a colour by being boil'd. Then take it off the fire, and ftrew into it half an ounce or three pinches of rocb aluuiy or Roman alum^ pulveriz'd, whicl^ kft is reddifh an a little beneath the cheeks, and the other parts near, 1a CAR In thefe it is that you muft well obferve nature, for painting being no more than an imitation of nature, every deviation from her is a blemifli, and truly a fault. Now having dead colour'd, drawn, and dirpofed of your tints, you muft proceed to fhade, ftippling with green for your flefh, mixing therewith, according to the rule prefcrib'd for tints, a little blue for the fading parts ; and on the contrary a little yel- low for the ftronger parts, or fuch as are neareft to you. On the extremities of the fhades, next to the lights, you muft im- perceptibly blend your colour with the ground of the flefti, firft with blue, then with red, agreeable to the part you are upon ; and if this mixture of green does not darken enough at firft, you muft go over the fhades with feveral repetitions, fometimes with red, and fometimes with green, always ftippling till the whole be perfefl. And if with the colours you cannot give your fhades all the ftrength they ought to have, you may finifh the darkeft parts with orpiment, oaker or vermilion, and fometimes with biftrel only, according to the colouring you would make, but lightly, laying it on very thin. You muft ftipple upon the lights with a little vermilion or carmine, mixt with a good deal of white, and a very little oaker, to iofe them with into the fhades, and make the tints die away imperceptibly into each other, taking care while you are ftip- pling or hatching, that your ftrokes follow the out-line of the ilefh; for although your hatching muft crofs in all directions, that ought to appear a little more, becaufe it rounds ofF the; parts. And becaufe this mixture might make the colouring too red if it was always ufed, moreover you muft endeavour to confound the tints and the fhades with blue, a httle green, and a great deal of white, fo that it be very pale ; but with this you muft not work upon the cheeks, nor upon the extremities of the lights, no more than with the other mi The " CAS f CARTON, 1 IS a defign drawn on ftrong paper, to be af- CARTOONjj terwards calk'd through, and transfer'd on the fre(h plaifter of a wall to be painted in frefco.

Befides what is faid of making a cavity for cafting in wax, fee WAX, (fee the articles FOUNDERY and STATUES) it will be no hard mat- ter to conceive how figures are made of PL AISTER ; for it being eafily tempered , and runnini^- as eafily, 'tis poured into the mould, and fometimes the figures are taken out all in one piece, efpecially when the founder is matter of his bufmefs, and well experienced in it. All the art is to chufe good plaijler in ftone, that there may be no coal among it ; it ought to be well burnt, well pounded, very white, fifted through a fine fieve : however, if it is a great figure, 'tis moulded at feveral times, and even feveral parts of the figure, in each piece of the cavity, are half fill'd before they are fet together, that they may hold the better, and the betteir form all the parts. We fee by what Pliny writes, that the cuftom of making moulds of plaijler is very autient \ and that 'tyvas made ufe of about CAS about earthen figures and plaifter figures along time before It was known how to caft in metal. CASTING Figures in LEAD. There are not fo many precautions necefiary when figures are caft in LEAD, as when they are done m brafs ; becaufc lead is not fo ftrong. See STA^ TUES. The workman only fills the cavities with earth well managed, of what thicknefs he pleafes ; then he fills all the mould with plaijier or tile-dujly with which the foul is made. When the foul is finifli'd, all the pieces of the mould are taken afunder, to take ofF the earth ; and then being clos'd a- gain, are put about the foul, but at four or five inches diflance. That interval is fill'd with coal from top to bottom ; all the gaps between the pieces of the mould are fill'd with bj-ick^ and the coal being fet fire to, 'tis all lighted. This is to feeth the foul, and dry the plailter mould which the earth had wetted. When all the coal has been well lighted, and after it is gone out of it felf, the workman takes a pair of bellows, and blows off the afhes that may have got into the pieces of the mould ; then thofe pieces are join'd together again as before about the mould ; all the chapes are well ty'd with cords, and cover'd with plaijier ; after which the melted lead is pour'd into the mould, which lead fills the fpace which was taken up by the earth ; nor is it necef- fary to earth the mould as in cafting in brafs, unlefs *tis for great figures. The tools us'd in cafting in lead are the fame the plummers ufe. ja^ FRANCIS CAVEAU, who engrav'd a great many \Ki plates, us'd this mark. FREDERICO CASA^UBON, alias KERSEBOOM, was born at Solingen a cky of Gerfnany in the year 1623. At eighteen years of age, he went to Amjlerdam to be inftruded in the art of painting; to Paris in 1650, and work'd fome years under Monfieur le Brun ; but afterwards was fent to Italy by the Chancellor of France, and maintained there by that minifter for fourteen years, two whereof he fpent with Nicholas Pou/Jin^ of whofe manner he was fo nice an imitator, that fome of his pieces were taken for his. Thus qualified for hiftory painting, he came to England \ but not finding encouragement that way, he bent his ftudies tov/ards portraits, wherein he was not unfuccef- ful, either as to drawing or likenefs. He was the firft who brought over the manner of painting on glafs, (not with a print, as the common way now is) in which he perform'd fome hi- ftories ana heads exceedingly well. Perfpedtive he underftood thoroughly, having been difciple to tvro excellent mafters in i VoL.L I that C E M that art ; and was, in fhort, an accompliflicd painter.

Mix glair of eggs with quick lime, and this cement will join broken pieces-of glafs together, and all earthen pots, fo that tl:ey will never break in the fame place again. 2. Or thus. Take old liquid varnifh and join the pieces with it; tie them together, and dry them well in the fun, or in are oven, and they will never unglue again ; but you muil not put hot liquor into them. 3.

This in a few days will be as hard as a ilone. 8. Take of calcin'd flints two pound, quick lime four pound, as much Knfced oil as may temper the mixture; this is a very iirong cenienr, but with liquid varnifh would be f^ronger. 9.

CERUSS a preparation of lead, commonly call'd white lead, and by the chymifts calx of lead. Ceriifs is made of very thin lamina: or plates of lead, fo laid as to receive and imbibe the fum.cs of vinegar, phc'd in a \ cHl'l over a moderate fire. The lamina:, or plates, are by means hereof converted into a white ruft, which is gathered together ; and being ground up with water, is formed into little cakes. Cerufs makes a beautiful white colour, and is much us'd by painters both in oil and water colours.

I 2 At C H A At the fame time, take another body and diflblve in it three ounces of quickfilver, in twelve ounces of the fame aqua forth i then mix both the folutions together into a larger body, which fet into the fame bath of warm water, or afh furnace ; then add to it three ounces oi fal artnoniac, which diflblve over a gentle fire , then add to it half an ounce of zaffer^ and a quar- ter of an ounce of viangancfe prepar'd by little and little, with as much Fcretto o( Spain^ alfo by little and little; for fear the mat- ter coming to fwell too much, fhould break the vefiel. Add to all thefe ingredients half an ounce of a-ocus 7nartis calcin'd with fulphur-, as much fcales of copper three times cal- cin'd, which ought to boll like manganefe ; as much blue lake (fuch as is us'd by painters) and the fame quantity of red lead, the whole reduc'd to powder. In putting in thefe powders, you muft gently flir the glafs body, that they may the better incorporate with the aquafortis, but be fure to take care that there be not too much heat ; then Itop the mattrafs (or glafs body) very well, ftirring it well every day for ten days, that the powders may well incorporate, and that rhey may always appear as feparated from the Vv^ater. Set the large glafs body into a fand furnace, in a temperate heat, or rather empty it into a glafs cucurbit, after you have well luted it at the bottom, and fet it over the fame fire, fothat the aqua forth may evaporate in twenty four hours ; and at the bottom of the veflel you will have a yellow powder, which keep fafclv it) glafies for ufe. When you are to make the Chalcedony^ take white cryftal in glafs, well purified, and that has been often melted ; for cryftal new made, is not fit for that operation, becaufe the colours will not ftick to it, but are confum'd by the frit. Put about ten pounds of this cryitalline glafs into a pot, and when it is well melted, put in about an ounce ar.d a half of your yellow powder at three different times, mix the glafs well with it each time, that the powder may incorporate with it, the glafs beina^ thus well mixt ; let it ftand an hour, then mix it once more, and let it ftand for twenty four hours ; then mix it again for the laft time, and make an cfTay of it, it will give a yeilowifli azure colour. Having made your efiay, and found your matter right, the pot may be taken t)ut of the furnace, and when it is cold, youll have the colours which fliall reprefent the wavings of the fea, and uther fine things. But to have a very fair Chalcedony^ you muft perform a fe- cond operation, to join to the firft, by taking four ounces of tartar cdi\c\vid^ one ounce of chimney foot well purified, one 'quarter of an ounce q( emus martis calcin'd with fulpbur, mix the C H A the whole together, then put it into the melted metal at five or fix different times ; other wife the impetuous fwelling-of the me- tals would break the pot, and the whole would be loft i which may be avoided by putting it in by little and little, ftirring it each time well, that the matters may incorporate j alfo make the pot boil, and let it ftand twenty four hours. After which time you may work it into what you pleafc. Which fet into the furnace to whiten, and fee if the glafs pleafe you, if it be green without, and blue, white, red, yellow, and of all other colours, like jafper and oriental agate. If looking on it obliquely, it be red like fire, and held to the fiin, it fhews the colours of the rain-bow by refledlion of the rays ; if fo, then it is fit to make all forts of velTels, which may be polifh'd at the wheel. If it be pale and clear, more calcin'd tartar and foot muft be added to it, as before, ftirring it well to make it incorporate ; then let the glafs ftand and purify feveral hours, and then you may work it, as you pleafe. Chalcedony is much us'd for the efEgies of Kings and Princes, for heads, cups, and many other velFels ; principally for fcals, becaufe it is eafily engraven, and the wax will not ftick to it. A fecond fpecles of CHALCEDONY finer than the forpier, 1 . Put a pound of aqua foriis, and three ounces of coppel'd filver, granulated into a glafs body, in order that it may be the better dilTolv'd. 2. Put alfo a pound of aqua fortis, and five ounces of mcrciity well purified, and pafo'd through a glove into another glafs body, and clofe it well. 3. Put alfo a pound of aqua forth with two ounces o^ fal ar- moniac, into another glafs vefTel to be diffolv'd. When it is diffolv'd, add to it crocus mariis, prepar'dytr^//(j of Spa in y leaves of copper calcin'd, by means of fulphur, of each half an ounce; reduce the whole into powder, putting them in one after the other, and by little and little, for fear the matter fhould break the veffel. 4. Put one pound of aqua fort:s, with two ounces of fal ar- moniack into another earthen body, and when the whole is dif- folv'd, add fuccellively as before of good crude antimony, of blue enamel, fuch as is us'd by painters, of red lead, and of vitriol well purified, each half an ounce, all of them well pulveriz'd ; thefe alfo muft be put in by little and little as before, for fear of breaking the veffel, then clofe it tvell. 5. Put alfo one pound of aquafortis^ and two ounces offal ar- moniack into another glafs body, and when diffolv'd, add two ounces of zaffer prepar'd, a quarter of an ounce of manganefe of Piedmont, alfo prepar'd, half aa ounce of thrice calcin'd copper and an ounce I I ox C H A cf anyiahar ; reduce all to a fine powder, and put them in hy little and little into the velTcl, taking care that the powders don't by too much fwelling break the veflel, then clofe it well. 6. Put a pound of aoua fcri'is, and two ounces cf fal armo- niac^ i'Uo a fixth veffel of the fame bignefs as the refl, and as foon as it is dilTolv'd, caft in two ounces of ceriifs by little and little, for that wiil alfo caufe a fermentation. Then add the like weight of painter's red lake, and as much of iron fcales from the anvil, putting it in by little and little, for the reafons before men- tioned ; and in a word proceed very flowly in all thefe opera- tions, flopping all the veflels well. Set all thsfe veffels on a gentle fire of afhes, or in a warm bath, to haflen the folution of the materials, they mufl be flirr'd at leaft fix times a day, for twelve days, in which they muft continue \\ that heat, that the aqua fortis may the better penetrate the povvder.^, and they communicate their tinilures the better to the glafs. The twelve days being ended, put the whole into a large glafs crucible, and lute it well for fear of breaking, pouring them gently in out of the fix matrafTes one after the other, having firft well ilirr'd each of them ; then fet this cucurbit on a gentle afh fire, and having fitted a head and receiver to it, and luted the joints well, then gently diftil all the aqua fortis that is in the body, for the fpacc of twenty four hours, making a very gentle fire towards the tx\>^, otherv/ife the powders may be fpoil'd by too much heat, and the fpirits which ought to remain in the powder, would pafs into the receiver. Then they will remain at the bottom of the vefiel of a yel- lowifn red colour, which keep in a glafs well ftopp'd for ting^ ing alafs or cryflal, which is yet better. The third and lad way of making a CHALCEDONY. This though fomething more tedious furpafles the two other in beauty. 1. To make this preparation : Take the aqua fortis^ of which put one pound into a glafs matrafs, with four ounces of leaf fil* ver to difiblvc, then flop the matrafs. 2. Put a pound of the fame aquafortis^ with five ounces of mercury purified vv^ith fait and vinegar, after the following man-' ncr. Put common fait into a wooden difh, fprinkle it with vinegar, and add to it a little common fair water to make it difiblve, put in the mercury, and fi:ir it well with a wooden pefile to drav/ out the blacknefs, repeat the wafhing them often with fa't and vinegar, till there be no more blacknefs ; then dry them v/ith warm linen or cotton, and pafs it through a glove; thtty it will be purified and fit to put into the aquafortis. When it is diilblv'd, ftop the matrafs and keep it. I 3, Take C H A 3. Take another glafs body, put into it another pound of 4aqua forth ^ with three ounces of fine filver calcin'd. Amalgamate the fdvsr with the mercury, as the gold fmiths ufjally do (See AMALGAMATION) and put it into a ciu- cible, with its weight of common fait purified. Then fet the crucible on hot coals, that the mercury may evaporate, and that only the filver may remain at the bottom, which will be purified and calcin'd. Tiien add to that calcin'd iilver, an equal v/cight of common fait purified as before, mix them v/ell together, and fet thtni over the fire in a crucible to calcine them again ; then wafli them well with warm water to take out the fait, and afterwards put this filver into a glafs vial filled with common water, boil it, till one fourth of it is confum'd, then let it cool and fettle to the bottom, after that decant oiTthe v^ater, and put more upon it. Repeat this procefs with frefh water three times, and at the fourth dry the filver, and put it into the aqua fcrtis., and ftir it well and flop the matrafs. The method of purifying common SALT, is as fellows : Difiblve fea-falt in a convenient quantity of common water, boiling it for the fpace of two hours; then let the water reft, that the earthy part of they?/// may fettle to the bottom ; then filter the water and evaporate it in an earthen veflel, or rather in a glafs cucur- bit, till thtfalt remain dry at the bottom. Diflblve this fait again, making the water boil, then let it fiand for the dregs to fettle, after which filter it and evaporate it as before ; which you muft continue to do, till there are no taoxz fceces or dregs, and it Vv'ill be well purified and prepar'd. In order to continue the preparation of the materials. 4. Put a pound oi aqua fortis into a glafs matrafs, and add three ounces of purified fal armoniac ; that Ls to fay filtred and whitened, till it leave Vio faces or dregs, as has been fhcwn in common fait; then diflblve a quarter of an ounce of filver in that water, and ftop the vefTel well. 5. Put alfo another pound of aqua fortis into another g^afs matrafs, with three ounces of purified fal armoniac, that is to fay, filtered and whitened till it leave no fcsccs or dregs, as has been fhewn as to common y^// ; then diffolve a quarter of an ounce of filver in that water, and itop the vefTel well. 6. Put alfo another pound of aqua fortis into another glafs matrafs, with two ounces o^ fal armoniac when it is diiTolv'd, put into that water cinnabar and crocus martis calcin'd with ful- phur as above ; of ultramarine and feretto of ^pain prepar'd, of each half an ounce, having reduc'd all to a fine powder; this mufl be put in by little and little, for fear of breaking the vef- fel by the fermentation ; which they make with the aqua fortis^ then itop the matrafs. I 4 7. Put C H A 7. Put a pound oi equa forth into another matrafs, and dif- folve in it two ounces oi fal armomac as before j add to it of cro- cus mariis calcin'd with calcin'd tin, known among the glafs men, of zc^r defcribed and nn?2^/'tfr each half an ounce, pow- dering them all very well, putting them in by little and little, as before, then flop the matrafs. 8. Put alfo another pound qI aqua forth into another matrafs, and diflblve in it two ounces oi fal armoniac ; then add an ounce qf fmall leaves of copper calcin'd, half an ounce of fcales of cop- per thrice calcin'd, half an ounce of mangancfe of Piedmont pre- pai'd, and half an ounce of fcales of iron, which fall from the Imith's anvil, the whole being reduced to a fine powder ; which throw in by little and little as before, then flop it well. 9. Put another pound of aqua forth into another glafs body, and add to it two ounces of fal armoniac^ the diflblution being made, put to it half an ounce of red lead by little and little, and one ounce of fcales of copper, half an ounce of crude anti- nomy, and as much caput mortutim of vitriol purified, all being reduc'd to a fine powder ; then ftop the matrafs. X o. Put another pound of aqua forth into another glafs ma- trafs, with two ounces of fal armoniac, add to this water orpi- ment, white arfenic and painters lake of each half an ounce; let the whole he finely powder 'd, put them into a matrafs by lit-Je and little as before, and ftop it up well. It has not been repeated at each operation, that you muft fet your matrafs on an afh furnace over a gentle heat, or in a warm bath to haften the folution of the materials ; becaufe it has been faid, that it muft be always done in the preparation of thefe things, which are for tinging thefirft fpecies of Chalcedony. All the nine matrafles mentioned in this procefs, muft remain fifteen days in the fame heat, and be often ftirr'd daily, that the water may the better operate on the materials, fubtilizing them, and well opening their tinclures. Then put all thefe materials v;ith the aqua fortis into a large glafs body, by little and little, that they may unite well together ; clofe the body, and fet it on the fame heat, ftirring it well for fix days. Alter this, take a large glafs cucurbit well luted half way up the body of it, and fet it on an afii furnace, put mto it all the materials out of the body ; fit a head and receiver to it, lute the joints well, and diftil it for twenty four hours over a gentle fire, left the colours fnould be fpoii'd, that the water may pafs gently over, and the fpirits remain in the powder, which of green will become yellow. Thus putting that powder in the requifite dofe (as has been taught m the firft fpecies of Chaludony) into purified metal, mad? C H A made of broken pieces of cryftal, and not of frit; and adding to it in its due time calcin'd tartar, chimney foot, crocus tnart'is made with vinegar, as has been direfted, and thefe materials will give an opacity to glafs, which in twenty four hours time may be wrought, managing it well with proper tools and often beating it, and you will have things of an extraordinary beauty, greater than can be imagin'd. CHARGE, 7 [in painting] is an exaggerated repre- OVER-CHARGE, Mentation of any perfon, wherein the likenefs is preferv'd, but withal ridicul'd. Few painters have the genius to fucceed in thefe Charges, the method is to pick out and heighten fomething already amifs in the face, whether by way of defect or redundancy ; thus v. o-. if nature has given a man a nofe, a little larger than ordinary, the painter falls in with her, and makes the nofe extravagantly long, or if the nofe be naturally too (hort, in the paintino he makes it a mere ftump, and the like of the other parts. CHARITY, is reprefented in painting, ^c. by a woman all in red, a flame on the crown of her head with an infant fucking, on her left arm and two other ftanding up, one of which is embraced with the right. « The red colour denotes Charity, the flame fignifies that Cha- rity is never idle, but always a<5live ; the three children fhew the triple power of Charity, for Faith and Hope without her fignifies nothing. CHASTISEMENT, is reprefented in painting, &c. by a fevere furious fellow with an ax in one hand, as much as to fay he will give but one blow, and a lion by him worrying a bear. The ax is a token of Chajlifement, the moft fevere as is the lion in that pofture. The King of Tenedos made a law, that whoever committed adultery fliould be beheaded, and did not fpare his own fon. CHARON Pluto's ferriman, who carries fouls over the three rivers of hell, Acheron, Cocytus and Styx, is defcrib'd old, yet exceeding robufl and ftrong, clothed with a black mantle, hanging ioufely over his fhoulders ; and alfo fometimes with long curl'd black hair, and clad in a robe of cloth of gold. By Cha- ron \% fignificd Time, and whereas he is fuppos'd to have the tranfportation of fouls, from one fide of ihofe rivers to the othery is intimated that fo foon as ive are horn, and brought forth int9 the world, it doth carry it along by little and little unto our deaths ; and fo fetteth us over thofe rivers, whofe names by interpretation fignify forrowfulnefs, for that we pafs this life in mifery and ad- verfty, CHASTITY, C H I CHASTITY, is reprefented in painting:, ^V. by a motJei^, hcneft faced woman, holding a whip in one hand, as if fhe would correct herfelr, clothed with a white robe; on her gridie is written cr.ii:g3 crrpus msum, I chaftife my body. At her feet Cspid lies conquer'd with his bow broken and he blinded. The whip denotes chaftifement, the Cupid with his bow broken that no concupifcence has dominion over her. yjtf uaj to Tnake CHINA, er f.ne E^rthm-vjart \ bsuj to Ena- mly Painty a>:.i Gild tbem. Porcelaine, China, or fine Earthen-ware, is enamell'd with our white ftuff", which is already prefcrioJ for metals ; and its painting the fame, and of fuch colours as we have propofed for enamels. The cuftom of enamelling on earlhen-ware is of greater an- tiquity than that on metals ; for in the time of Pcrj'mna, who generouilv undertook the reftoration o( Tarquin to the Rsman £ovemmsnt in the Confulate of Faler. Publiccla and Hyrct. Phuz'iliiiSy aim. mund. 3444, five hundred and four years before the coming of Chrift, or thereabout?, rhe practice of enameling on ware was ufed in the eiiates of that prince ; and what gives us verv good reafon to believe this is the name Poralar.e^ which has an affinity to Pi^femis, though alter'o by the corruption of time. 5o it is alfo caJl'd Fayence from Fayence in the duchy of Urbin, where in the time of Michael Angeb and Raphael Urbin, this art was praSifed. And as the fecrets of nature are daily more and more difco- vet'd, fo has time employ 'd the invention of man to improve this, and make it more excellent, not only condefcending to en- amelling, but proceeding alfo to painting and pourtraying thereon fe\'eral curioflties, to which at length are added the ornaments of gilding. Thefe pieces of ware are of a very general ufe over all the world, as for ornaments over chimney-piece?, on cabinets and tables, or boards. The choiceft come to us from China, and next to them tbofe dor.e at St. Clcud and Rou-n ; but there are very good made in Hoilandy at Saz»nne in Itdly, and feveral other places in France. The painting and enamel'ingon thefe, b what wc are proper- Ir obliged to take notice of in cur art ; howev^er, we fhall fiightly touch upon the compofition ar.d moulding the ware, and for this we will prefcribe fine and delicate methods fufficient enough to anfwer the fjtisfaction of fuch as employ themfches in this art, and of thofe perfons whofe curiofity leads them to enquire auer thing?, whereof they are not already inform'd. C H I The furnace for making of CHINA muft be large, with an opening proportion'd to the veiTel you are to place therein ; of thefe there are feveral forts, but the mofl commodious muft be made as follows. You may fhape this furnace round or fquare, but the fquare is beft, becaufe of the opening ; it muft be made of good brick, and fuch ftufF as can moftly endure the fire, of what bignefs you pleafe, with three divificns ; the loweft for afhes muft be a foot high, that the air may be communicated through its open- ing to the fire ; the middle ftory is for the fire, and muft be un- derlaid with a very good grate, to feparate it from the under ftory, with an opening for the fuel, and be vaulted above, about a foot in height. According to the fize of your furnace, this vault muft be made, like that of an oven, and have an hole in the middle, of the fame fliape as the furnace, round or fquare, and proportion'd to its bignefs, through which the flame may tranfmit itfelf to the uppermoft ftory, where the velTels are put to bake in j this laft ftory is to be at leaft two foot high, and its opening fourteen or fifteen inches, to put and draw the vefiels eafily in and out ; the top muft be vaulted too with a round or fquare hole, and over that a funnel, for the conveniency of the flame and fmoak which it draws out. All the opening, efpecially to the two uppermoft, muft be of ftrong brick, or crucible earth, or rather of iron, well luted within fide, which muft fliut and open eafily, and be very exact and fit, that the fire may not fuck in any cold air, which might break the velTels. This furnace will ferve alfo for many other ufes, as to melt, reverberate, calcine, cement, and feveral forts of work in the laboratory of chymijlry ; becaufe in it all the degrees of fire may be found, by the help of the lower opening, and the funnel of the chimney. You may alfo for baking your China, make ufe of the fur- nace hereafter defcrib'd, where we difcourfe of painting on glafs, putting thereinto your veflel of crucible earth for baking the ware in, and then cover'd over with a vaulted coverlid, with a hole at top to let out the flame and fmoke cf the reverheratory fire; for this reafon there will be no occafion in this fort of fur- nace for any other opening, becaufe the baking of veflels with your ware, are put in at top before the coverlid is laid on, and fo the fire circulates about it, and it becomes very red, whereby the China-ware is baked , as is done in baking of pipes. To inahc the Stuff far CHINA-WARE. The compofitlon for this muft be very fine, becaufe of the ware, and not fuch 3S k ufed for ordinary veflels, we will therefore prefcribe the manner CHI manner of making it, to prevent the unfuccefsful attempts of I fuch as may be ignorant. For this you muft take of fhells of every fort vj^hich are white and tranfparent, grind them well on a marble, then fearce and reduce them to an impalpable powder. To make your pafte of this powder, firft diflblve an ounce of' very white gum arabick in a pail of water ; when 'tis well dif- folv'd and mixt with the water, diflblve therein about a quarter as much quick lime as your powder weighs ; then ftir and mix it very well, and afterwards put in the powder and ftir all to- gether, and knead it as they do mortar. Of this ftuff form your vefTels, according to the different forts you defire ; let them half dry or more, in the air, before you polifli them with your fmooth inltrument of copper or iron for that purpofe, and fo leave 'em until they dry thoroughly. Being very well fmoothed and dried, glaze them over with your white enamel, prepared as hereafter direfted, and fo fet them dry in the furnace to bake and finifli ; vi'here having kept them a convenient time, let the fire go out of it felf. When the furnace is cold, take 'em out and paint them, and put them in again to bake a fecond time, obferving what diredlions have been already given concerning thefe mat- ters ; and when the fire is gone out, and the furnace cold, you have the ware in perfection ready to take out for \::{e. You may make your China-ware alfo of pure earth, let it not be red tho', but white or gray ; you may try the fufficiency of it after 'tis prepar'd, by baking fome beforehand ; and when it comes out of the furnace found and uncracked, 'tis good and fit for your purpofe. The preparation confifts in drying well, and reducing it to a very fine powder ; then put it into fair water, wherein has been already diffolv'd a little gum arabick ; but moft of thofe that make it, employ only water without gum. After this, you make your difhes, fet 'em to dry, polifh, glaze, bake, paint, and finifh them as before ; all which, thofe who work at them know better than I can exprefs it. How to Enamel CHINA. For this, take of the milk-white enamel, grind it very fine, as painters do their colours \ put the powdjer afterwards into a glafs cucurbit, pouring fome aqua- fortis thereon ; let it digeft a little to cleanfe off its impurities, and become fine and tranfparent ; then pour off the aqua-forth^ wafhing the powder in water over and over again ; grind it af- terwards with a little gum-water on your marble, and fo glaze the veffels with it within and without 3 dry them in the air, and bake them as before in the furnace. Or you may heat the veffels to a rednefs in the furnace, and melt the enamel : when it is in a perfe^ fufion, dip the fmal- 2 ler C H I ler vefTels therein, and pour of it on the larger, for they will take no more on them than will ferve them ; fet them by turns in the furnace, flopping it very well to avoid the air; balce, cool your furnace, and finifli them as before ; then take out the difhes, paint and bake them over again, obferving all the former directions. To paint CHINA. This is done as the enamel, but much more eafily, the figures being only juft dafh'd over in compari- fon to them ; however you muft grind your colours v/ith oil of fpike on the marble, as has been already faid, and fo paint on the difhes flory, landfcape, or any other fancy ; but you muft never expedt to have them fo complete and handfome, as thofe painted on the enamel'd plates, becaufe the former are finifh'd ftanding, and fo enlarge in length or breadth ; whereas the other are done on flats, and lying j befides, the difhes are for the moft part round, and not fo eafily painted, for if they could be as neatly done as the enamel, they would be excefHvely dear. To Gild CHINA. You mufl fir ft grind fome Jhade-earth on a marble, with linfeed-oil, prepared as fhall be {hewn anon, with which trace out your figures, which muft be two whole days a drying ; after this, apply very thin leaf-gold, and with a fharp graver, ftiape the figures, and then put the difhes in an oven, as foon as the batch of bread is drawn out ; let the heat be no greater than one's hand may endure, elfe the vefTels would crack ; leave them in it for two or three hours or more, if the oven be not too hot ; you may elfe make ufe of your furnace, by giving it the fame moderate degree of heat, as experienced perfons are well acquainted with. Another way. This is much more handfome and lively, be- fides that it can't be effaced ; you may with it gild vefTels en- tirely, or border, or give them any luflre you think convenient for ornament, and it will look as well as fine gold. You muft firft wet over the places you would gild with gum- water lightly, then apply your leave?, and fo let them dry : this is enough for plain gilding ; but if you would have it carved or figured, you muft make ufe of a fteel graver, and afterwards bath the gold with water, wherein borax has been diflblv'd, .powdering it in the mean time with cryftalline powder, or miJk- white enamel reduc'd to a very fine powder ; then i^t the difh on a reverberatory fire to melt and be polifh'd j thus you'll have as fine a piece of ware as can be. The way to prepare Linfeed-oil for Gilding o/" CHINA. Take a Paris pint of linfeed-oil in an earthen pot which will hold about two Pam pints; put this on a fire, and when it begins to boil, throw in twice the bignefs of a fmali egg of gum-ara- bick C H I hick pulveriz'd ; ftir all well until it be diflblved ; then put in ait onion of an ordinary fize, and the like weight of garlick cut fmall ; when the oil boils well, and fwells up by the force of the good fire which muft be underneath, pour it out into ano- ther fuch pot, and fo in and out of each pot to the other, until all be very well mixt; then put it on the fire again, adding halfjl an egg-fhell of powder of maftick, and ftir it very well ; as foon as it boils again, it will foam and have a great froth, which muft be fcumm'd off; and then take it ofF the fire, and brew the ingredients together, with the two pots as before ; con- tinue to do thus with it, or ftir it on the fire, until it rife no more. This done, take a very dry toaft of white bread to take oflT the greafe (the oil ftill boiling) and when you put in the toaft, you muft at the fame time put in fome pin-duft ; ftir all together, and let it ftand for twenty- four hours afterwards; ftrain the oil through a linen-cloth, in which is fome very fine fand, the better to filtrate it, and take off" the greafe, and fo you'll have it pure and clear, which bottle up for your ufe. Or you may (both ways being good enough) firft mix with the oil two ounces of gold litharge pulv^eriz'd, adding the gum arabick as foon as it begins to boil ; and to purify it, let it filter through a linen-cloth full of fand, while its hot, into a glafs- bottle, wherein is already half an ounce of fine camphire pow- der, fhaking the bottle w&xy well until the oil be cold ; after- wards lay it in the fijn for fifteen days, and it will be entirely purged, and the longer 'tis kept will be the better. The imitation of CHINA or PORCELANE ware upon tea- tables^ tea -boards^ he. upon gold and filver grounds. After the tables or other utenfils have been prepared as directed,} mark out the defigns upon them, make ovals or rounds upon them in a good difpofition, fo as to be uniform, or well adapted to the defign, that they may anfwer one another in a regular manner ; then pafte on fome paper in proper places, and when the paper is dry, draw your defigns upon them, and paint them with water colours ; then with a brufh lay gold or filver fize, and when that is near dry, lay on leaf gold or filver ; and when all is dry'd, varnifti over with the ftrongeft varnifh, except only the ovals or circles of painting, for thofe muft be done with the white varnifh, which is fo tranfparent, that all the painting will appear through it. If you lay on a gold ground, or any colour darker than that, then let your painting be blue and white ; or if it is filver or light ground, then ufe the moft fiery colours in your paintings. 1 To take off the figure from any piece of CHINA-WAREJ iho the perjon has not bsin acquaintfd with drawing. If there bi C H O be upon a difh, plate, cup, iJc. any figures that you like afnJ would take ofT, you mufl lay a piece of oiled paper over them,- fo as to hold the piece fteady till you can trace out the lines of the figures ; then lay the oily paper on a paper black'd on one fide, and the black'd paper on a clean paper ; then trace the lines with a pen or blunted point of a needle, till the lines are all imprefs'd on the white paper, and draw them over with a black lin'd pencil, and mark the {hades where they ftparate from the light parts of the colour, that fo you may lay on your co- lours as you fee them painted on the China-wnre ; then cut out the figures clofe to the out-lines, and fix them upon ycur ground of whiting and fize, or fize with ground chalk, with ihlck giim arahick and water ; and when they are quite dry, paint them, the lighter parts in water colour, and the fliady parts with var- nifli niix'd with the darker colours ; when thefe are dry, wafii all over with the white varnifli before the fire, but take care that it be not fo nigh the fire as to make the varnjfli rife in blifters. When the varnifh is dry, lacker it again with the fam.e var- nifti, and repeat this a third time; then fcrape fome tripoii very- fine, and with a foft rag dipt in water, take up a little of the tripoii at a time, and polifh it by gentle rubbing till it is fmooth ; then wafti off the tripoH with a foft fpunge and water, and tl)eri wipe it oft' with a dry fine cloth ; and when it is thoroughly dry, if it be a white varnifli, clean it with whiting and oilj and if a black varnifli, with lamp black and oil. But the common way is to cut out prints, and pafte tl^iem on fuch parts as is thought fit, and then to colour them with water colours, and to varnifli them with white varnifli. This is an eafy way of painting, becaufe ths fliades of the prints, when you lay on a tranfparent water colour, will give the light and (hade that colour to your purpofe, without ufing a dark and light colour. CHOLER is reprefented in painting by a meagre youth of a fallow colour, with a haughty look, being almoft naked ; hold- ing a drawn fword in his right hand ; on one fide a fliield with a flame in the middle, and a fierce lion on the other fide. Lean, becaufe heat predominates, which the fliicM denotes ; his yellow colour fliews his choler ; the drawn fword, his hafti- nefs to fight ; his nakednefs and his impetuous pafTion docs not fufFer him to provide for himfelf: the lion his animofity. CHOROGRAPHY is reprefented in painting, '<^c. by a young lady in a changeable colour'd habit, plain and ftiort ; in her right hand a meafuring fquare, a globe on the ground with a little part defigned s iii, her left compailcs. The C H R . The changeable habit denotes the different taking of fituati- | ons ; her fhortnefs fignifies the taking plans of dominions more briefly, when they take. the leaft part for the greateft ; the inftru- ment, the taking by it the limits of every dominion ; the com- paflcs denote, the fetting them to diftinguifh the confines from one another. CHROMATICK [in painting] a term ufed to fignify the colouring, which makes the third part of the art of painting. CHRYSOLITE, a precious ftone of a yellow colour. The Chryfolite is the Tepaz of the moderns. CHRYSOLITE, is alfo a general name which the ancients gave to all precious ftones, in which the yellow or gold was the prevailing colour. When the ftone was green, they call'd it Chryfoprafm^ the, red and blue too had their particular denominations, which ex- prefs'd their colour, the gold being fignified by Chryfo ; which ftill began the name. The modern jewellers call that a Chryfolite, which the ancients caird a Topaz or Chryfopras, which is a precious ftone, green and diaphanous, fome of which caft a luftre of gold ; this ftone is fo hard, that it will eafily endure the file, andfometimes there are pieces of them found big enough to make ftatues of, witnefs that of Juba King of Mauritania, made in honour of Queen Arfmoe, wife of Ftolemceus Philadelphus, of the height of four cubits. To make a pajlefor an oriental Chryfolite. To imitate this ftone, take two ounces of natural cryftal prepar'd, eight ounces of minium in fine powder, add to it twelve grains of crocus Martis made with vinegar, mixing the whole well together. Then put the whole into a crucible, and fet it in a furnace, leaving it there a httle longer that it may have time to purify from the lead. Then will you have a pafte for the oriental Chryfolite, which will appear very admirable, fet with a foil in gold. The way to make CHRYSOLITE. Take ten ounces of our powder of natural cryftal and Saturnus glorificatus, (which fee) to which add one ounce of crocus martis prepar'd ; the whole reduc'd to fine powder, well mix'd, and put into a crucible co- vered and luted, and bake it as directed for other of the like metals, and you will have a fine chryfolite colour^ which will be of the native green. LODOVICO CIGOLI or CIVOLI, born in the year 1559, ^w^vsA Andrea del Sarto and Correggio ; liv'd at Florence and RomCi excell'd in hiftory, died in 1613, aged fifty four year?. GIOVANNI C I N GIOVANNI CIMABUE of noble d^fcent, the father of the jirjl age or infancy of modern painting, a difc.ple of cer- tain ordinary Greek painters brought to Florence^ barn in the year 1240, where he liv'd, exceli'd \\\ hiftory and architedture, died in the year 1300, aged lixty yczi^. He was of the family of the CIMABUE, in thofe days re- puted noble, and being a promifing child was fent to fchool to the monaftery o( Santa Maria iiovella. But inftead of minding his book, he fpent al! Jiis time in draw- ing of men, horfes and the like upon paper or the backfide of his books. Much about this time thofe who govern'd in Florence^ invited fome painters out oi Greece, that the art of painting which was .totally loft by the deluge of calamities, which for divers hundred years had overwhelm'd Italy, and had ruin'd all the publick fa- fcricks, and the produ(3: of the induftry of the ancients, might be reftor'd among the Italians. There Cimahue following his fecret inclination, us'd to get from fchool, and pafs the whole day with thofe painters to fee them work. So that at laft his father perceiving how fond he was of that art, agreed with the Gree^ painters to take him un- der their care, which they the more readily did, judging he was very likely to fucceed in his profeffion. Accordingly, in a (hort time, he furpafs'd his mafrers both in defign and colouring, for they not at all attentive to improve their art, had contented themfelves with a plain, flat manner, as may be feen in thofe of their works that have been prefcrv'd to our time; but Cimabue though he imitated them, yet he had a iTMich freer way, as appears by his works that remain. CINNABAR, a mineral ftone, red, heavy, and brillant, found chiefly in the quick-filver mines ; cail'd alfo vermilion. The ordinary vermilion is nothing elfe but Cinnabar ground up with fpifit of wine and urine. Cinnabar, is either native or fa £^ it ious. The native or mineral Cinnabar, or vermilion, which ito advantage, the lights and (ha- CHIARO SCURO, J dows of a piece; boJi wich rtgard to the ealing of the eye aud the effed of the whgle piece. Thus C L A Thus when a painter gives his figures a ftrong relievo, loofens them from the ground, and fets them free from each other, by the management of lights and fhadows, he is faid to underftand the Clair Obfcure. The Claro Obfcuro makes one of the great divifions, or branches of painting, the whole of a pi<5lure being refolvable into light and Jhadow. The doctrine of Clair Obfcure will come under the followirg rules. Light may be either confidercd in regard to itfclf, or to its effe£ls, the place wherein it is difFas'd, or its ufe. For the firft light is either natural or artificial., Jiatural light cither cames immediately from the fun, which is bri.-k, and its colour various according to the time of the day, or 'tis that of 2^ clear air, thro' which light is fpread, and whofe colour is a little bluifli, or a cloudy air which is darker; yet reprefents objects in their genuine colours with more eafe to the eye. Artificial light proceeds from fire or flame, and tinges the ob- jeft with its own colour, but the light it proje6ls is very nanow and confin'd. For the fecond, the efFe»Sls of light are either principal, as when the rays fall perpendicularly on the top of a b^dy without any interruption, or glajicing^ as when it Hides along bodies, of fecondary, which is for things at a diftance. 3. YoT t\\s place, it is either the open campagne, wliich makes objects appear with great foftiiefs, or it is an inclos'd place, where the brightnefs is more vivid, its diminution more hafty, and its extremes more abrupt. 4. For the ufe or application, the light of the fun is always fuppos'd to be without, and over againft the pidlure ; that it may heighten the foremoft figures, the luminaries themfelves never appearing, in regard the beft colours can't exprefs them. The chief light to meet on the chief group, and as much as pofiible on the chief figure of the fubjecl. The light to be purfued over the great parts, without being crof;»'d or interrupted with little fhadows. The full force of the principal light to be only In one part of the piece, taking care never to make two contrary ligh::-:. Not to be fcrupuloufly confin'd to one univerfal light ; but to fuppofe other accelfory one?, as the opening of clouds, {ifr. to looien fome things and produce other agieeable efFedts. Laflly the light to be different, according to the quality of things, whence it proceeds, and the nature of the fubjec^s which receive it. As {ox Jhadmxjs, they are diftinguifh'd, I. Into ihofe form'd pn the bodies themfeJves, by their proper relievo's, K 3 2. Thofa C L A 2. Thofe made by adjacent bodies, thofe that make the parts of any whole, and the different effects, according to the difference of places. For the firft, fince the different effefts of light only appear by fhadows, their degrees muft be well manag'd. The place which admits no light, and where the colours are loft, muft be darker than any part that has relievo, and difpos'd in the front. The reflex or return of the light, brings with it a colour borrow'd from the fubjeft that reflects it, and flies off at a greater or lefs angle, according to the fituation of the refledling body, with regard to the luminous one ; hence its effedts muft be dif- ferent in colour, and in force, according to the difpofition of bodies. Deepenings which admit not of any light or reflex, muft ne- ver meet on the relievo of any member of any great elevated part ; but in the cavities or joints of bodies, the folds of drape- ries, ^c. and to find occafions for introducmg great Ihadows, to ferve for the repofe of the fight, and the loofening of things, inftead of many fhadows which have a pitiful effedl. For the fecond, the fhadows made by bodies, are either in plain and fmooih places, or on the earth, wherein they are deeper than the bodies that occafion them, as receiving lefs re- flex light; yet ftiil diminifh as they depart further from their caufe, or on the neighbouring bodies, where they are to follow the form of the fame bodies, according to its magnitude, and its pofition in refpe£t to the light. For the third, in fhadov^s that have parts, the painter muft obferve to take for a light in a fhadowed place, the teint or luftre of the light part; and on the contrary, for the fliadow in the lightened part, the teint or luftre in the fhadow ; to make an agreeable affemblage of colour, fhadow and reflex in thefha- dowed part. But without interrupting the great maffes of fhadows, to avoid forming little things in the fliadow, as not being perceiv'd un- lefs clofely look'd at ; and to work as it were in the general, and at one fight. Never to fet the ftrong fliadows againft the light, without foftening the harfh contraft by the help of Tome intermediate co- lour, ti^.ough the mafs of light may be plac'd either before or be- hind that of the fliadow ; yet it ought to be fo difpos'd, as to illumine the principal parts of the fubjecft. For the fourth, the effedls of fhadov/s are different, as the place is cither wide and fpacious, as in thofe coming immediately from the fun, which are very fenfible, and their extremes pretty abrupt 5 from the ferene air^ which are fainter and more fweet, fro Hi C LI from the dark air, which appears more diffus'd and almoft Im- perceptible ; and thofe from an artificial light, which makes the fhadows deep, and their edges abrupt ; or as it is more narrow and confin'd, where the lights coming from the fame place, make the fhadow more ftrong, and the reflex lefs fenfible. CLAIR OBSCURE, ? is alfo us'd to hgnify a defign, con- CHAIRO SCURO, 5 fifting only of two colours, moft ufu- ally black and white ; but fometimes black and yellow, or it is a defign only wafti'd with one colour, the (hadows being of a dusky brown colour, and the lights heightened up with white. The word is alfo apply'd to prints of two colours, taken ofF at twice ; whereof there are volumes in the cabinets of the cu- rious in prints. The word Clair-Ohfcure is a compound of two others, Clair is us'd by the French for thofe parts of a painting which reflvdt the moft light ; and comprehends not only the lights themfelves, but alfo thofe colours that are luminous. By Obfcure^ is meant not only all the fhades, but alfo all the colours that are dusky. CLEARNESS is reprefented in painting, i^c. by a naked youth of a noble afpedi:, furrounded with a great fplendour and brightnefs, with the fun in his hand. His youth fhews him acceptable to every body, and is faid to be illuftrious fike the fun that illuminates every thing in the world. CLEOPHANTUS of Corinth, made the next improvement upon Ardices of Corinth, who firft attempted to fill up his out- lines. But as he did it with one fingle colour laid on every- where alike, his pieces, and thofe of H)giciiion, Dinias and Cbarmas his followers, from thence got the na:i:e of Monochro- mata (■y/z.) pictures of one colour. FRANCES de CLEYN was a Dutch painter and mafter of the tapiftry works to King Charles L zt Mortlack for which he painted cartoons in diftemper; lie was very eminent for his in- vention, and made feveral defigns that were extraordinary fine for painters, gravers, fculptois, ^c. amongft v/hich are cuts of fome of Ogilhys books. He died ziMortlack a little before the rettoration. CLIO, one of the mufes, the patronefs and inventrefs of hi- ftory, is reprefented in painting with a coronet of bays ; hold- ing in her right hand a trumpet, in her left hand a book, upon which may be written Hijioria.

For a beautiful sky, fitted for fair weather, ufe Bice tem- pered with zvhite^ laying it in the upper part of the sky, (as you fee proper) under which you may lay a thin or fairit pur" fie with a fniall foft brufii, working the undermoft purple irtto the upper mole blue ; but fo as that the blue may ftand clear and 2. For the horifon, or near the fame, lay a fine thin majlicot, v/hich work from beloW upwards, till it mix with the purple ; after which, you may take a ftronger purple, making here and there upon the former purple, as it were the form of clouds as rature requires. 3. Upon the mnjlicot, you may alfo work with minium mix'd with cerufs, to imitate the fiery beams, which often appear in hot a'd clear fummer weather. 4. To imitate gl ;ry with a great ftiining light of a yellowifli colour or the fun-beams, you muft ufe ?naJiicot or faffron mixt with red-lead, and heightened with fhell gold or the like. <;. A cloudy sky is imitated with pale htce, (hading the clouds afterwards with a mixture of feveral colours ; a fair sky requires clouds of a greater fliade, with purple 6. The clouds in a rainy sky muft be fhaded with indigo and lake; in a x\\^\x sky, with black and dark blue, fmoaky, mak- ing a blaze with purple, minium and cerufs. 7. The clouds^ at fun rifing or fetting, muft be made with miniumy cerufs and purpie, making fcatiering ftrokes underneath the clouds with ininium and majiicct, or minium and faffron ; fo that the fcattermg upward may appear faint, and fomething fiery below afar otf, near the landfcape. 8. Make a fiery sky with pale blue, fmoothing it downwards, which muft be aiterwards mingled with a ftrong red-lead mixt with cerufs, making long diminutive ftrokes like the fun-beams upon the blue sky, with which let fall feme purple ftrokes, much like the faid beams ; then fweeten one into another with a foft bmfti-pencil, wet in gum- water, not too ftrong. 9. Make a fair sky, by ufing fair bice alone, and tempering it by degrees with moie and more white ; fmoothing one into the other from above downwards, and Ihading it as you think proper, and as nature require?.

DON GIULO CLOVIO, born 1498, fcholar of Giuh Romano, liv'd at Rome and in Hungary ; excell'd in miniature, hiftory and portraits; died in the year 1578, aged eighty years. T -j-^ HERMAN COBLENT has put this mark under rG|-4 the four Evangelifts and other plates ; one of Davidy -^ -^ of Judith and Lucretia ; and afterwards Adrienus Hubertus ufed this mark with cxcudit. COCHINEAL, a drug us'd by dyers in giving red colours, efpecially crimfons and fcarlets. It is brought to us from the Weji-Indies, but authors are not agreed as to its nature ; fome taking it to be the grain of a tree, and others to be a kind of worm. Of the firft opinion is Pomet^ and of the latter F. Plumier. But it fhould feem that there is both a Cochineal that is a grain, and another that is a worm, tho' they have both been equally dillant from the truth in the defcription they have given of it. This COL This opinion is founded on the account given by Dampler, who gives a precife defcription of each kind ; which if be not true, 'tis at leaft more likely than any opinion yet propos'd. His defcription of each is as follows. The Cochineal worm is an infedl ingendred in a fruit, refem- bling a pear ; the flirub which bears it is five or fix foot high. At the top of the fruit grows a red flower, which when mature, falls on the fruit; and that opening difcovers a cleft two or three inches in diameter. The firft then appears full of little red in- fects, having wings of a furprizing fmallnefs, and which would dye and rot there if not taken out. The Indians therefore fpreading cloths under the tree, (hake k with Poles^ till the infects are forc'd to quit their lodging, and fly about the tree ; which they cannot do many moments, but tumble down dead into the cloth, where they are left until they be entirely dry. When the infedl flies, it is red ; when it is fal- len, black ; and when dry, white, though it afterwards changes its colour. There are whole plantations of the Cochineal tree, or Tonna, as the natives call it, about Guatimala, Chepe, and Guexach in the kingdom of Mexico. Cochineal grain, or as Dampier calls it, Sylvejiris^ is a red ber- ry, growing in America, found in a fruit, refembling that of the Cochineal tree or Tonna. The firft {hoots produce a yellow flower; then comes the fruit which is long, and when ripe, opens with a cleft of three or four inches. The fruit is full of pippins or grains, which fall on the leaft agitation, and which the Indians take care to ga- ther. Eight or ten of thefe fruits may yield about an ounce of grain. This berry yields a dye, almoft as beautiful as that of the in- feft; and a perfon may eafily be deceived in them, though the firft is the leaft efteem'd by much. VIVANO CODAZZO, call'd VIVIANE, call'd DALLE PROSPECTIVE, born in the year 1599, fcholar o^ Augujlino TaJJh, liv'd at Rome, excell'd in buildings and ruins, died in the year 1674, aged feventy five years. ^ STEPHEN COLBENSTAGH, Sc. Roma. He Kp, engrav.'d tlie paintings of Domcnichmo^ and afed this .•■X^-J mark. . . ADAM COLONI, commonly call'd the Old, was a Dutch painter, born in Roterdam, but who refided a great while in England, and became efpecially eminent for his fmall rural pie- ces, cartel, country wakes, fire pieces, isc. he alfo copied many pictures of beafts ^.htx Bajfam, particularly thofe of the royal col- iedlion, which are efteemed his bsft pcifoimances. He died in ; Londoii COL London in 1685, and lies buried in St, Martinis Church, aged fifty one years. HENRY, alias ADRIAN COLONI, was the fon of the forementioned, he was inttru'cI of particles very heterogeneous, or diffimilar to each other, /. e. feme of them, as it is highly probable, are larger, and others lefs. For a ray of li2;ht, as E F (See plate fig. VI.) being receiv'd on a refrac^tory furface, as A D in a dark place is not wholly refrafied to L, but fplit as it were, and diifus'd into feveral little rays ; fome of which are refracted to L, and others to the other intermediate points between L and G, /. e. thofe particles of the light, which are the moft minute, are of all others the moft cafily and moft confiderably diverted ; by the adlion of the re- frading furface out of their refiilinear courfe towards L : and the reft, as each exceeds another in magnitude, fo is it with more difficulty and lefs confideiably turn'd out of its right line to the points betweeen L and G. See REFRANGIBILITY, Now each ray of light, as it differs from another in its degree cf refrangibility, fo does it differ from it in Colour \ this is war- ranted by numerous experiments. I'hofe particles v. g. which are moft refrafted, are found to conftitute a ray of a violet colour, /. e. in all probability, the moft minute particles of light, thus feparately impell'd, excite the ftiorteft vibrations in the retina^ which are thence propagated by the folid fibres of the optic nerves into the brain, there toi excite the fenftuion of violet cokur ; as being the moft dusky and languid of all Colours. See VIOLET. A<.ain thofe particles which are the leaft refracted, conftitute a radiUus or ray of a red Colour^ i. e. the largeft particles of light excite the longeft vibrations in the retina^ fo as to excite the fenfation of a red Colour., the brighteft and moft vivid of all Colours. See RED. The other particles being in like manner feparated according to their refpedtive magnitudes into little rays, excite the inter- metUate vibrations; and thus occafion the fenfation of the mter- mediate colours, much in the fame manner as the feveral vibra- tions of the air according to their refpe^Stive magnitudes, excite the fenfation of different founds. To this it may be added, that rot only the more dif^inctand notable Colours cA red., yelloiu, blue. Szc. have thus their rife from the different magnitudes and ref anj^ibiliry of the ra)s; but alb the intermediate degrees or feints of ihc fame coiour, as of yel' 'hw up to greeriy of red down to yellow., &c. Further, the Colours of thefe little rays not being any adven- titious modifications thereof, but Ci:nnate, piimitive and neccf- fary properties, as confifting in all probability, in the magnitudes of their parts, muft be perpevual and immutable, / e. cannot be changed by any future refradion or reflection^ pr by any modi- fication whatfoevcr, Thii COL This is confirm'd by abundance of experiments; all endea- vours having been ufed, after feparating a colour d ray from thofe of other kinds, to change it into fome other Colour by repeated refractions, but to no effeft. Apparent tranfmutations of Colours indeed may be effc£led, viz. where there is an afTembiage or mixture of rays of diffe- rent kinds, the component colours never appearing in their na- tural hue in fuch mixtures; but always allay 'd and temper'd with each other ; v.hence refults a middling kind of colour, which by refradlion may be feparated into component ones; and thofe after feparation being remix'd, return to their former C»- lour. Hence the tranfmutations of Colours, by mixing thofe of dif- ferent kinds, are not real ; but mere appearances and deceptions of the fight : for the rays being again fevered, exhibit the fame colours as at fiift. Thus blue and yellow powders well mixt, appear to the naked eye green ; yet without having pafs'd any alteration, when viev/'d through a microfcope, the blue and yd- low particles ftill appear diftindi. Hence there arife two kinds of colours, the one original and /imple, produc'd by homogencal light, or by rays that have the fame degree of refrangibility, and the fame magnitude of their parts ; fuch as red, yelloiu, g^^^^'t hlue^ a violet, purple, orange^ and indigo, with all their intermediate teints and gradations. The other kind of Colours is fecondary or heterogeneous, com- pounded of the primary ones j or of a mixture of rays diffe- rently refrangible, djV. There may alfo be fecondary col:)urs, produc'd by compofi- tion like the primary ones, or thofe confifting of homogeneal light, as to the fpecLes or appearance of the Colour ; but not as to the permanency or immutability thereof. Thus yellow and blue make green ; red and yellow, orange ; orange and yellowijb green, yellow, and in the gener-al, if any two Colours be mix'd, which in the feries of thofe generated by the prifm, are not too far apart from their mixture, refuks that colour, which va the faid feries is found in the mid way between them; but thofe fituated at too great a diftance, do not io. Indeed, the more any Colour is compounded, the lefs perfe£l and vivid it is; by too much compofition, they may be diluted and weakened, till they ceafe. By compofition, there may be produced Colours, not unlike any of thofe of the homogeneal light. The moft extraordinary compofition is that of whitenefs, for to this, all the primary colours abovementioned are xequired; and ihofe to be raixt in a certain degree. Hencw COL Hence it is that white is the ordinary colour of light; h'ght be- ing nothing elfe but a confus'd aflemblage of rays of all Colours. If the rays of different Colours do thus begin to be feparated by one refraction of one fingle furface, that feparation is much promoted, fo as even to become fenfible to the eye by a double refradlion. This is obferv'd in the two furfaces of any glafs ; provided thofe furfaces, be not parallel, but of all others, it is moft fenfible in the two faces of a triangular prifm ; the phaenomena whereof, as they are the touchftone of all theories of Colours^ and as they contain the theory of that is here delivered, we (hall lay down as follows. 1. The rays of the fun, tranfmitted through a triangular prifm, exhibit an image of various Colours (the chief of which are red, yellow^ g^een, blue and violet) on the oppofite wall. The reafon is, that the differently colour'd rays are feparated 11 by refraiStion ; for the blue rays v. g. mark'd with the dotted ij line (See plate fig. VII.) which begin to be feparated from the \ reit, by the firfl refraftion in d d o{ the fide ca oi the prifm i abc (as alfo in the firft furface of the globe of water abcy ( fig. VIII, ) are flill further feparated in the other fide of the prifm b f , (as alfo in their egrefs out of the globe ^ ^ c ) by a fecond refradtion in c e, in the fame diredlion as the former : whereas on the contrary, in the plane glafs ebcf, fig. X. (as alfo in the prifm g I Of fig. IX. now plac'd in another fituation) thofe blue rays which begin to be feparated from the refl in the firfl furface in d d by a fecond refraction, the contrary way pafs out paral- lel, /. e. remix'd with all the colours of the other rays. 2. That image is not round, but oblong ; its length, when the prifm is an angle of fixty or fixty five degrees, being five times its breadth. The reafon is, that fome of the rays are refracted more than others ; and by that means exhibit feveral images of the fun ex- tended lengthwife, inftead of one. 3. Thofe rays which exhibit yellow, are turn'd further from the rectilinear courfe, than thofe which exhibit red, thofe which exhibit ^ri?^«, than thofe which exhibit ^'^Z/ozy; but of all others, thofe which exhibit violet the moft. Accordingly, if the prifm, thro' which the light is tranfmitted, be turn'd about its axis, fo as the red, yellow, green, &c. rays be projected in order, thro' a narrow aperture into another prifm, plac'd at the diltance of about twelve feet; theyellow, green, &c. rays, though falling through the fame aperture in the fame man"* ner, and on the fame point of the fecond prifm, will not be refraCted to the fame place as the red ; but to a point at fome diltance from it, on that fide to which the rotation is made. 4 This VU J/if.-f K. 7W. i.rt> /,>« M^ym.'^/^.r,^, vu COL This is what Sir Ifaac Newton calls the experlmentum crucis ; being that which led him out of the difficulties into which the firft phaenomenon, iJc. had thrown him, and plainly (hew'd a different degree of refrangibility, and a different Colour corre- fponding thereto in the rays of light ; and that yellow rays, V. g. are more refraded than red ones, green ones more than yellow ones, and blue and violet ones moft of all. 4. The Colour of coloured rays well feparated by the prifm, are not at all chang'd or deftroy'd by pafling an illuminated me- dium, nor by their mutual decuflation, their bordering on a deep {hadow ; nor their being reflected from any natural body, or refrafted through any one, in a place howfoever obfcure. The reafon is, that Colours are not modifications arifing from refraftion or reflection, but immutable properties ; and fuch as belong to the nature of the rays. 5. An aflemblage of all the kinds of ^^/(?«rV rays, colledled either by feveral prifms, by a convex lens or a concave mirror, or in any other manner, from what we call whitenefs j yet each of thefe after decuflation, becoming feparated again, exhi- bits its proper Colour : for as the ray was white before its parts were feparated by refraftion ; fo the parts being re-mix'd, it becomes white again, and colour'd rays when they meet to- gether, don't deftroy one another, but are only interfpers'd. Hence a red^ g^e^^i yelloWy blue and violet Colour, being mixt in a certain proportion appear whitijh, i. e. are of fuch a Colour as arifesfrbm white and black mix'd together; and if there were not fome rays abforb'd and loft, would be plainly white. In like manner, if a paper cut into a circle, be ftain'd with each of thofe Colours feparately, and in a certain proportion ; then fwiftly turn'd round its centre, fo that the fpecies of Co- lours be mixt together in the eye, by the brisknefs of the mo- tion, the feveral Colours will difappear, and the whole paper ap- pear of one continued Colour j which will be a mean between white and black. 6. If the rays of the fun fall very obliquely on the inner fur- face of a prifm, thofe that are refle<5led will be of a violet Colour ; thofe that are tranfmitted red. For the rays were colour'd before any feparations, and by how much they are the more refrangible, by fo much they are the more eafily reflected ; and by that means are feparated. 7. If two hollow prifms, the one being fill'd with a blue fluid, and the other with a red one be joined together ; they will be opake, though each being apart will be tranfparenf. For the one tranfmitting none but blue rays, and the other none but red ones, the two together v/ill tranfmit none at all. 8. All COL 8. All natural bodies, efpeciaily white ones, vlew'd through a prifm held to the eye, appear fimbriated or bordered on one fide with red and yellow ; and on the other with blue and violet. For thok fimbria are the extremes of intire images which the rays of any kind, as they are more or lefs refracted, would ex- hibit nearer or at a greater diftance, from the real place of the objed. 9;. If two prifms be fo plac'd, as that the red of the one, and the purple of the other meet together in a paper fit for the pur- pofe, incompafs'd with darknefs ; the image will appear pale, and if view'd through a third prifm, held to the eye at a proper diftance, it will appear double, the one red, and the other purple. In like manner if two powders, the one perfeftly red, and the other blue, red and purple be mix'd ; any little body co- ver*d pretty deeply with this mixture, and view'd through a prifm held to the eye, will exhibit a double image, the one red and the other blue ; by reafon that the red and purple, or blue rays are feparated by their unequal refraction. fo. If the rays tranfmitted through a convex lens be receiv'd ©n a paper, before they meet in a focus ; the confines or boun- dary of light and fliadow will appear ting'd with a red Colour -, but if they be receiv'd beyond tht focus, with a blue one. Becaufe in the firft cafe, the red rays being fomething more refratfted, are the higher j but in the fecond after decuflation in the focus, the blue ones. Laflly, if the rays about to pafs through either fide of ti»c fupilla, be intercepted by the interpofition of any opake body near the eye ; the extremes of bodies plac'd, as if view'd through a prifm, will appear ting'd with Colours, though thofe not very vivid. For then the ra^'^s tranfmitted through the reft of the pupilla, will be feparated t^ refraction mto Colours, without being diluted with the admixture of the intercepted rays, which would be re- fraded in a different manner. And hence it is, that a body, view'd through a paper, piercM with two holes, appears double and alfo ting'd with Colours. Of the COLOURS rftbin plates. As rays of different Co- lours are feparated by the refraSf ion of prifms, and other thick bodies j fo are they feparated, though in a different manner m the thin lamellcs or plates of any pellucid matter, v. g. the bub- bles rais'd in water thickned by fc)ap, l^c. For all lamellcs under a determinate thicknefs, tranfmit rays of all Colours, v.'ithout refletling any at all, but as they increafe in thicknefs, in arithmetical proportion, they begin to reflsct firft hlue rays j then in grder grcen^ ydbw ai;d red^ more and more mixt COL mixt and dilutee!, till at length, arriving at a certain thicknefs, they reflect rays of all Colours, perfectly intermixt with white. But in whatfoever part a flender lamella refledts any one co*- lour, V. g. blue, in that part it always tranfmits the oppofite colours, V. g. red or yellow. It is found by experiment, that the difference of C^/y^r of a plate, does not depend upon the medium that encompafl'es it, but the degree ofvividnefs does; cateris paribus, the Colour will be more vivid, if the denfer medium be encompafs'd with a rarer. A plate, cateris paribus, reflects more light, as it is thinner, as far as a certain degree of thinnefs ; beyond which, it reflects no light at ail. In plates, the thicknefs of which increafe in an arithmetical progreiTiun of the natural numbers, i, 2, 3, 4, 5, ^c. If the firft or thinnefl: reflect any homogeneal ray, the fecond will tranf- niLt it , and thus is the fame ray alternately reflected and tranf- mitted, /. e. the plates correfponding to the odd numbers, i, 2, 3, 5, 7, y^. will reflect the fame rays, that thofe correfpond- ing to the even ones, 2, 4, 6, 8, tffc. tranfmit. Hence an homogeneous Colour in a plate is faid to be of the Jirjl order; if the plate reflect all the rays of that Colour. In a plate, whofe thinnefs is in a threefold proportion to the firft, it is faid to be of the fecond order, in another, whofe thinnefs is five times that of the firft, it is faid to be of the third order, ^c. A Colour of the firft order, is the moft vivid of any, and fuc- ceflively the vivid nefs of the Colour increafes, as the quantity of the order increafes ; the more the thicknefs of the plate is in- creafed, the more Colours it reflects; and thofe of more different orders. In fome plates the Colour will vary as the pofition of the eye varies, in others it is permanent. COLOURS of natural bodies Bodies only appear of dif- ferent Colours, as their furfaces are difpos'd to reflect rays of this or that Colour alone, or of this or that Colour more abundantly than any other; hence bodies appear of that Colour which arifes from the mixture of the reflected rays. All natural bodies confift of very thin, tranfparent lamella ; which if they bu fo difpos'd in regard to each other, as that there happen no reflections or refractions in their interltices, thofe bo- dies become pellucid or tranfparent, but if their intervals be {o large, and thofe are fill'd with fuch matter ; or fo empty (in re- fpedt to the denfity of the parts themfelves) as that there hap- pen a number of reflections and refradtions within the body, the body in that cafe becomes opake. Vol. I. L The COL The rays which are not reflefted from an opake body pene- trate into it, and there fuffering innumerable reflexions and re- fradlions at length unite themfelves, to the particles of the body itfelf. Hence an opake body grows hot the fooner, as it reflefts light lefs copioufly ; whence we underftand the reafon why a white body, which reflects almoft all the rays that ftrike upon it, heats much more flowly than a black one, which reflects fcarce any. In order to determine that conftitution of the furface of bodies, Wherein their Colour depends ; it muft be obferv'd, that the fmalleft corpufcles or firft particles of which furfaces are made up, are moft thin and tranfparent, and feparated by a medium of a different denfity from the particles themfelves. So that in the furface of every coloured body are innumerable fmaller, thin plates, correfponding to thofe of bubbles ; where- fore, what has been obferv'd of thofe may be underftood of thefe. Hence it is gathered, that the Colour of a body depends upon the denfity and thicknefs of the parts of the body, between the pores of the furface, that the colour is more vivid and homoge- neous, as the parts are thinner; x.\\2l\. ea;ter is paribus ih^izid^zxis: are the thickeft when the body is red, and the thinneft when violet ; that the parts of bodies are ufually much denfer, than the medium contain'd in their interftices ; but that in the tails of peacocks, fome filks, and generally, in all bodies whofe Colour varies, according to the fituation of the eye, it is lefs; and that the Colour of a body is the lefs vivid to the eye, as it has a denfer medium within its pores. Now of the feveral opake bodies, thofe confifting of the thin- neft lamella are black, thofe confifting either of the thickeft la- mellce, or of lamellce very different from each other in thicknefs, and on that account fitted to refledl all Colours^ as the froth of water, ^6-. are white. Thofe again confifting ol lamellce, moft of which are of fome intermediate thicknefs, are blue, green, yellow or red, inafmuch as they reflect the rays of that particular Colour, much more copioufly than that of any other Co/(?«r; moft of which laft theyj either abforb or extinguifh, by intercepting them, or elfe they! tranfmit light. j Hence it is, that fome h'quors, v. g. an infufion of lignum\ nephriticum appear red or yellow, if view'd by reflected light,! and blue by tranfmitted light ; and leaves of gold yellow if view'd: by reflected light, but green or k^ue in the latter. To this we mfay add, that fome of thofe powders, us'd by painters, have their Colour chang'd by being very finely ground ;; ivhich muft be caus'd by the comminution, or breaking o thei. COL their fmall parts into others fiill fmaller, juft as a lamella has \t% Colour altered by altering its thicknefs. In fhort, thofe odd phaenomena arifing from the mixture of liquors of jilferent Colours, can no way be better accounted for, than from the various a£lions of the faline, fffc. corpufcK's of one liquor with the colaorcd corpufcles of another ; if they unite, the mafs will either fwell or fhrinic, and thereby its denfity will be altered ; if they ferment, the fize of the particles may bedimi- nifhed, and tiiereby thecolouied liquor may become tranfparent ; if they coagulate, an opake liquor may be produc'd of two tran- fparent ones. Hence it is eafy to conceive, why a colour'd liquor in a glafs of a conical figure, plac'd between the eye and the lights appears of a different Colour m different parts of thcveflel; there be- ing more and more rays intercepted, as they pafs through a longer or ftiorter fe6lion of the vefTel, till at the bafe they are all intercepted, and none feen but thofe that are reflected. From the various Colours of natural bodies. Sir Ifaac Newton obferves, the bignefs of their component parts may be eftimatcd; for that the parts of bodies do properly exhibit the fame Colour •with a lamella of equal thicknefs provided the denfity in both be the fame. The feven Painting COLOURS in general 1. T\iQ cYaei whites zxefpodiumy cerufsy white-lead, Spanijh white, egg-jhells burnt. The spanijh white is thus made: Take tine chalk fix ounces, allum two ounces, grind them together in fair water, till it be like pap, roll it up into balls which dry leifurely ; then put them into the lire till they are red hot, take them out and let them cool.

And tttrnfde, litmofe blue, rofet, brafil, logwood 2ind fa^ff ran zxe more fit for wafniiig prints, than curious limning. COLOURS in painting is a term apply'd both to the drugs, and the teints produc'd by thofe drugs, varioufly mixt and apply'd. The principal Colours us'd by paip.ters are red and white-lead or cerufs, yellozv and red oakers \ fcveral kinds of earth, as um- ber^ orpiment^ lamp-black, burnt Ivory, black lead, cinnabar or vermilion^ gamboge, lacca, blue oind green ajhes^ verdegreafe, hi- Jire, biccy Jmalt, carinine, ultramarine ; each of which with the manner of preparing them, their ufes, ^c, are to be found un- der their proper articles. Of thefe colours fome are us'd tempered with gum water, fome ground with oil j others only mfrefco, and others for mi- niature ; all which fee under their proper heads. Painters reduce all the Colours they ufe under thefe two clafles, of dark and light COLOURS. Dark Colours are black, and all others that are obfcure and earthy, as umber, bifire, &c. Under light Colours are comprehended xvhite^ and all thofe that approach nearell it. Painters alfo diftinguifh COLOURS \niofimple and mineral. U nder Jimple Colours they rank all thofe which are extracted from vegetables, and which will not bear the fire, as the yel- low, made offaffron, French hemes, lacca, and other tindlures extra6led from flowers, ts'd by limners, illuminers, i^fc. The mineral Colours are thofe which are drawn from metals, dfff. and that are able to bear the fire : us'd by enamellers. Changeable and permanent COLOURS, is another divifion, which, by fome, is made of Colours. Changeable Colours are fuch as depend on the fituation of the objeds with refpedl to the eye, as that of a pigeon's neck, taf- feta's, l^c. the firit however, being attentively view'd with a microfcope, each fibre ef the feathers appears compos'd of feve- ral little fquares, alternately red and green ; fo that they are fix'd Colours. Kircher fays, that the changing, /. e. changeable Colour ob- ferv'd in the wings of pigeons, peacocks, i^c. arifes from the feathers being tranfparent, and of a figure refembling a prifm j and confequently the lights being differently refraded from them, and Permanent Colours are not exhibited by refradion, but by rc- dec^ion. M. Mariotti COL M. Mariotte obferves, that there are two different gradations or feries of Colours from white to black ; the one whiter yellow^ red and black, and the other white, blue, violet, and black, COLOURS in particular. CERUSS, grind it with glair of eg^s, and it will make a very good white. It is too yellow for fome purpofes, coarfe and gritty. WHITE- LEAD, grind it with a weak water of gum lake, and let it fland three or four days, and if it be afterwards mixt with rofet and vermilion, it will make a fine carnation. ^ To order white-lead fo, that it (hall neither ruft nor (bine, both which are of an ill effect in the art of limning. See the ar- ticle LEAD. Spanijh White, being ground with gum water, is the bed White of all to garnifti with. Lamp-Black, makes a good Black being ground with gum water. Vermilion. If it be ground with the glair of an egg, and a little clarified honey, to make it bright and perfect is good ; but native cinnabar is better and of a more lively Colour. Cinnabar Lake makes a deep and beautiful red, or rather pur- ple, almoft like to a red rofe, grind it with gu7n lake and turn' fole water ; if you will have it light, add a little cerufs, and it will make it a bright crimfon ; if it be to diaper, add only turn' fole water. Red-lead, grind it with (omtfaffron and a {i\ff gum- lake, the faffron will make it orient and of a marygold Colour. Turnfole, lay it in a faucer of vinegar, and fet it over a cha- fing cjifh of coals ; when it boils, take it cff, and wring it into a Ihell, adding alittle^y;;? arabick, let it ftand till it is diffolv'dj this is good for fhadowjng carnation and all yellows. Rofet, grind it with brafilc water, and it will make a deep purple ; put cerufs to it and it will be lighter ; grind it with lit- mofe, and it will make a fair violet. Spanijh Brown, grind it with brafile water, mingle it with cerufs, and it will make a horfe flefh Colour, It is not fo brisk and lively as Indian red. Bole Armoniack makes but a faint Colour, the chief ufe of it is in making fize for burni(h'd gold. Green Bice is to be ordered as you do blue Bice ; when it is moift and not thorough dry, you may diaper upon it with the water of deep green. Verdigreafe, grind it with juice of rue and a little weak gum water, and you will have a mofl pure^?Y^n ; if you would diaper with it grind it with lyeof r«f (or the dccodlion thereof) and it will make a hoary green, L 3 Diaper COL D'lU'pQT u^nVerdegreafe green with fap green ; ^\(o Verdegreafi ground with white tartar^ and then temper'd with gum water, gives a moft perfect green.

Ultramarine^ if you would have it deep, grind it with Ut- mofe water, but if light with fine cerufs and a little gum arabick water. In grinding Ultramarine and other Colours, be not too fwift in your motion, but let it be gentle and flow, becaufe the fwift- jiefs of the motion caufes the ftcnes to heat ; which will caufe your Colour to llarve or lofe fomewhat of its luftre, efpecially, if it be a Colour of no great body, as pink^ indigo, &c.

Obfervations on vegetable COLOURS. 1. A ftrong infufion of galls filtred , mixt with a ftrong and clear folution of vitriol^ makes a mixture as black as ink ; which, with a little ftrong oil of vitriol^ becomes tranfparent again. After which, by the afFulion of a little quantity of a ftrong folution oi fait of tartar, it regains its black colour. The firft black (altho' pale in writing, yet) being dry, appears to be good ink. 2. A decoction of red rofes, dried in fair water, mixed with ^ filtrated folution of blue vitriol, makes a black colour j and this being mix'd with a little aqua fortis, turns it from a black to a deep red ; which, by the affufion of a little fpirit of urine, may be prefently reduced to a thick and black colour. 3. Telloiu wax is whitened by difTolving it over the fire in fpirit of wine ; letting it boil a little, and then exhaling the fpirit, or elfe while it is hot, feparating it by filtration. 4. Fair water, mixt with a blood red tincture of benjamin, drawn with fpirit of wine, immediately makes it of a milk white colour. 5. Blacknefs may be taken away with oil of vitriol ; fo black pieces of filk or hair may be turn'd to a kind of yel- low. 6. A handful of lignum ncphriticum rafp'd, infus'd in four pound of fpring water, yields between the light and the eye an almoft golden colour (except the infufion be too ftrong ;) but with the eye, between the light and it (in a clear vial) a lovely blue, as indeed it is. This with fpirit of vinegar may be made to vanilh (ftill keeping its golden colour ;) and afterwards, with oil of tartar per dcliquium, may be reftored again. 7. Cloth dyed with blue and wood is dyed into a green by the yellow deco61:ion of luteola. 8. Syrup of violets, mixt with a high folution of gold in aqua regia, produces a reddifti mixture ; and with a high folu- tion of tilings of copper in fpirit of urine, a lovely fair green. 9. Syrup COL 9. Syrup of violets, mixt with a little juice of lemons, fpirit of fait, vinegar, or the like acid fait, will immediately bea me red ; but mix'd with oil of tartar, or a folution of pot aflies, will in a moment become a perfect green ; and the like in the juice of blue-bottles. 10. A good quantity of oil of tartar, put into a ftrong folu- tion oi verdegrcafey gives a delightful blue, which may be vari- oufly chang'd, by adding fpirit of urine or hartfhorn. 1 1 . Altho' red rofes hung over the fume of fulphur, lofe all their rednefs, and become white; yet oil of fulphur (which is nothing but the fumes condenfed) doth wonderfully heighten the tindlure of the fame, 1 2. Cochineal will have its colour far more heightened by fpirit of urine, than by rectified fpirit of wine ; and one grain of cochineal in a good fpirit of urine, being put into a hundred and twenty fix ounces of water, ting'd it (although but faintly) which amounts to above 125000 times its own weight. 13. Twenty grains of cochineal being mix'd with an ounce of faccharum faturni, will make a moft glorious purple colour ; and fo accordingly, as the quantity is either diminiftied or in- creas'd, fo the purple colour Ihall be either lighter or deeper. 14. A few grains of cochineal being mixt with the lixivium of quicklime in a due proportion, makes a fading purple colour of the greateft glory imaginable in the world. 15. The juice of privet berries with fpirit of fait is turned into a lovely red ; but with a ftrong folution of pot afhes into a delightful green. 16. Spirit of fait makes no confiderable change; but rather a lighter red upon things red by nature, as fyrup of clove gilli- fawers, juice of buck-thorn berries, infufion of red-rcfes, bra- file, hue. 17. Juice of jafmin and fnow drops, will turn into a deep greenifii yellow, by a ftrong alcaline folution (altho' the juice of jafmin, &c. before were of no colour.) 18. Buckthorn berries, being gathered green and dryed, are call'd fap-herries , which being infus'd in alum water, pro- duces a iair yellow (which is us'd by book-binders for the edges of bocks, and to colour leather alfo ;) being gathered when they are black, they are call'd fap-giten, and make a green colour, be- ing put into a brafs or copper veftel for three or four days ; or. a little heafed upon the fire, and mix'd with alum in powder^ and prelFed out ; fo put into bladders, hanging it up till it is dry ; and being gathered about the end of November, (when they are ready to drop) they yield a purplifti colour. 19. Tmdure of cochineal, diluted never fo much with fair water, will never yield a yellow colouf, A Tingle drop of a deep COL deep folution in fpirit of urine, diluted in an ounce of fair water, maices a fair pinic, or carnation. 20. Oil or fpirit of turpentine^ digefted with pure white fugar of lead, yields in a fhort time a high red tindture, which chy- miib call balfamum faturni. 21. Spirit of fait dropt into a ftrong infufion of cochineal or juice of black-cherries, makes prefently a fair red ; but dropt into the infufion of brafiUy a kind of yellow. So the filtrated tinc- ture of balauftin, mixt with good fpirits of urine, or the like, turns of a darkifh green ^ but with fpirit of fait, a high red- nefs, like rich claret wine ; which glorious colour may in a mo- ment be deftroyed, and turned into a dirty green, by fpirit of urine. 22. A high infufion of lignum nephriticum, mix'd with fpirit of urine, produces fo deep a blue, as to render the liquor cpakey which however vanifties, after a day or two, and leaves the hquor of a bright amber colour. Where you may take notice, that inftead of fpirit of urine, you may ufe oil of tartar, or a ftrong folution of pot-aflies. 23. Infufion of leg wood, in fair water (mixt with fpirit of fal armoniack) immediately tuins into a deep, rich, lovely pur- ple ; tvvo'or three drops is enough for a fpoonful, left the colour be fo deep as to be opake. 24. Spirit Qi fal armoniack will turn fyrup of violets to a lovely green. 25. An infufion of Uttnofe in fair water will in a clear glafs give a purple colour ; but will be wholly chang'd into a glorious yelloiu, by fpirit of fait being added. 26. The infufions and juices of feveral plants will be much altered by a folution of lead in fpirit of vinegar; it will turn the infufion of red rofe leaves into a fad green. 27. So the tincture of red rofes in fair water would be turn'd into a thick green, with the folution of minium in fpirit of vi- negar; and then with the addition of oil of vitriol the refolved lead would precipitate white, leaving the liquor of a clear high red colour. 28. It has not been yet found, that to exMbit the ftrong va- riety of colours, there is need that any more than thefe five be applied, viz. ivhite, blacky red, blue, yellow ; for thefe being varioufly compounded, exhibit a variety and number of colours ; fo many, that thofe who are ftrangers to painting, can hardly imagine. 29. So black and white varioufly mixt, make a vaft company of light and deep grays ; blue and yellow, a great variety of greens j red and yellnvj feveral orange tavjneys ^ red and whitey 3 a number COL a number of carnations ; red and blue^ feveral purples ; and thus are many colours produc'd, for which we want names. 30. Acid falts deftroy a blue colour; fulphureous, urinous, or fixed, reftore it. 31. Acid and alkalizate falts, with many bodies that abound with fulphureous or oily parts, will produce a red, as is manifeft in the tln£ture of fulphur, made with lixiviums of calcined tar- tar or pot a(hes. Of Preparing COLOURS. Colours, according to their nature, have each a particular way of preparation, vi%. by grinding, wafhing, or ftceping. The chief colours to be ground are thefe ; white lead, cerufs, cinnabar, lake, oker yellow and brown, pink, indigo., umber, cO" lens earth, Spanif) brown, ivory black, cherry Jlone black, lamp- black, Indian red, Indian lake. The chief colours to be wajh'd are ; red lead, majlicote, greeii bice, cedar green, ultramarine, blue bice, fmalt, verditer. The chief colours to be fteep'd are ; fap-green, faffron, turn" fole, Jlone-blue, Venice berries. The method of GRINDING COLOURS. Take the colour you would grind, and fcrape ofF from it all the filth ; then lay it upon the ftone, and with the muller^ bruife it a little ; then put to it a little fpring water, and grind all together very well, till the colour is very fine ; which done, pour it out in certain hollows or furrows cut In chalk-Itone, and there let it He till it Is dry, which preferve in paper or glalTes. Take care in grinding your colours not to put too much water ta them upon the Jlone, for they ought to be ground pretty thick like pulp or pap ; and they ought not to he left too moijl, but thick and clammy. If after your colour is dry in the Jhell, you can rub it off" with your fngerSy ii tnujl be better bound with gum ; and if there be too much gum, it will Jhine, and be apt to crackle off after it is ui'd. Of mixt and compound COLOURS. An ajh colour or gray is made by mixing white and lamp- black, or white with fmaper ; indigo and black make an afh- colour. To inake an azure or blue. Mix the azure with glue water, and not with gum water. A bay colour. Mingle vermilion with a little Spanijh brown and black. A bright crimfon. Mix tlndlure of brazile with a little cerufs ground with fair water. To mak< a crimfon lake. It is ufually made of the flocks fliorn COL fhorn off from crimfon cloth, by a lye made of falt-petre, which extrads the colour ; which precipitate, edulcorate, and dry in the fun, or in a itove. Tto make a fad crimfon. Mix the aforefaid light crimfon with a little indigo, ground w'th fair water. To make a fiame colour. It is made of vermilion and orpl- ment, mixed deep or light at pleafure: or thus j take red leady and mix it with mojiicote, which heighten with white. To make a glafs grey. Mingle cerufs with a little azure. To make excellent good greens. The liver of a lamprey makes an excellent green ; and yellow lay'd upon blue will change into green j fo likewife the juice of a blue flower de hice^ mix'd with gum water, will be a perfecl and durable green or blue, accord- ing as it is us'd. To make a light green. It is made of pink or fmalt with white, to make it whiter, if need require. To make a lead colour. It is made of white, mix'd with in- digo. To make a flcjh colour. Mix a little lake and red lead with white, a very fmall quantity of each ; you may make it as light or as red as you pleafe, by putting more or lefs white in it. If you would have a fwarthy complexion to diftinguifli a man's flefli from a woman's, put a little yellow oker among your flefh colour ; and for your fhadow, put a little more lake, and a fmall quantity of burnt umber. To make a murrey which is compos'd of purple and white ; it is. made thus, take cinnabar lake two ounces, white lead one ounce, and grind them together. To make a good murrey. Temper rofet with a little rofe wa- ter, in which a little gum hath been diflblv'd, and it will be good, but not better than the firft. To make a pure lake. Take urine ten pounds ; boil it in a kettle, and skim it with an iron skimmer, till it comes to eight pounds; to which add gum lake half a pound, alliim two ounces and a half; boil all till it is well coloured, which you may try by dipping a piece of linen cloth in it ; then add fweet alum in powder a fufficient quantity ; ftrain it, and let it ftand ; ftrain it again through a dry cloth, till the liquor be clear j that which remains in the cloth or bag is the pure lake. To make a deep purple. This is made of indigo, Spanijh brown, and ivhite. Another purple. Boil log-wood in vinegar and beer in a glaz'd [earthen veflel, adding thereto a little alum, till you tafte it to be ftrong on your tongue; when it is fufEciently bcil'd, ftrain out the liquor through a cloth, and keep it in a glafs clofc ftopt [for ufe. r$ COL To make a ydloiu green on purple. Buck-thorn herrtes gather- ed green, and fteep'd in alum water, yield a good yellow ; but being thorough ripe and black, they yield a good green ; and laftly, being gathered when they are ready to drop off, which is about the middle or end of November^ their juice mixt with alum water, yields a good purple colour. To make a pear green. Take white tartar and verdegrenfe ; temper them with ftrong white wine vinegar, in which a little gum arabick has been diffolved. Another purple Colour. Mix blue bice and lake together, or if you want bice, take blue verditer (but that is not altogether fey good) mix them well together, and it is done. If you want lake, you may inftead thereof ufe thick red ink, which will da' as well as lake in wafliing. To make cloud Colours. You may fometimes take blue verdi- ter, fometimes light majlicote fhadowcd with blue verditer, or lake and white, or red ink and white fhadowed with blue ver- diter. To make a Red Colour. Take the roots of the lefler buglofs^ viz. alkanet, and beat them, and ftrain out the juice, and mix it with ahun water. To make a Scarlet Colour. It is made of red- lead, lake and vermilion, y^t vermilion in this cafe is not very ufeful. To make a pure Purple Colour. Take finebrimftone an ounce and a half, quickfilver, fal arinoniac, jupiter, of each one ounce, pulverize the fak and brimftone, and make an amalgama with the quickfilver and tin ; mix all together, which put into a great glafs gourd ;■ make under it an ordinary fire, and keep it in a conftant heat for the fpace of fix hours. A Saffrsn Colour, is made oi Saffron alone by infufion. To make Fermilion. Take brimitone in powder four ounces, mix it with quickfilver a pound, put it into a crucible well luted, and upon a charcoal fire heat it till it is red hot, then take it off and let it cool. To make a Violet Colour. Take a little indigo and tindlure aibrafile, grind them with a little ccrufs. To make a Yellow. Take the 7'clliw chives in white lilies, fieep them in gum water and they will make a perfedl Yellow ; the fame (xom faffron and tartar tempered with gum water. TEMPERING of COLOURS. Take a little of any Co- lour, and put it inro a clean fhell, and add to it a icw drops of gum water, and with your finger work it about the Ihell, and let it dry, and when dry, touch it with your finger; if any Co- lour comes off, vou muff add ffronger gum water ; but being dry, if the Colour g'.ifter or fliine, it is a fign there is too much gum in it, which you may remedy, by putting in fair water. To COL ro HELP the defeat of COLOUR?. Some Colours, as lake, amber and others which are hard, will crack ; when they are dry in this cafe in tempering them, add a little white fugar candy in very fine powder ; which mix with the Colour and fair water in the fliell, till the fugar candy is difTolv'd. Thefe Colours., u?nber^ Spanijh brown, Colen-earthy cherry- Jlone and ivory-black, are to be burnt before they are ground or wafh'd. To BURN or CALCINE COLOURS. This is to be done in a crucible, covering the mouth of it with clay, and fet- ting it in a hot fire, till you are fure it is red hot through ; which done, being cold, wafh or grind them as before cJiredled. To prepare SHADOWS >r COLOURS. White is fhadcd with black.^ and contrary-wife, yellow with umber and the okersy vermilion with lake^ blue bice with indigo^ black-coal with r«- [ety Sic.

Put the Cc/w into a glaz'd vef- fe), and put fair water to it plentifully, wafli it well, and de- cant (after a while) the water ; do this fix or feven times ; at laft put the water (being juft troubled) into another glaz'd vefleJ, leaving the dregs at the bottom ; then into this fecond vef- fel put more fair water, wafhing it as before, till the water (be- ing fettled) be clear and the Colour remain fine at the bottom. Before you take the Colour out of the vejfel^ fpread it very thin^ about the fides thereof and when it is dry^ fome of it will fall to the bottom, which keep by itfelf; but the remainder which flicks tc the fides of the bafon is the beji of all^ which luith a feather , Jlrike off from the fides of the veffel^ for it will he finer than any four. STEEPING of COLOURS. Take a quantity of the Co- lour, and put it into a (hell, and fill the (hell with fair water, to which add {bme fine powder of ^/Avw, to raife the Colour -y let it thus fteep a day and night, and you will have a good Co- lour. Where note, fafFron fteep'd in vinegar gives a good Colour, and the Venice berries in fair water and a little allum, or a drop or two of oil of vitriol makes a h'lr yellow. But fome Colours are to be boil'd, as brafle, logwood, turnfole, rinds of wallnuts, wood foot, &c. thefe when boil'd are to be kept clofe llopp'd in glafle?, till you have occafion to ufe them. COLOURS us'd in DYING. There are in the art of Dying five Colours call'd Simple primary or mother Colours, from the mixture of which all the other Colours are form'd ; thefe are blue, red, yelloiu, brozvn and black. Of thefe Colours, varioufly mix'd and combin'd, they form the following Colours, panfy, blue and red; from the mixture of blue ?indfcarlet are forrn'd amaranth, violet znd panjj>; from the fame mixture of blue and crimfon red are forrn'd the columbine or dove Colour, purple, crimfon, a?naranth, panfy and crimfon violet. Here it is to be obferv'd, that they give the name oi crimfon to ay Colours made with cochineal* Of COL Of blue and red madder is dyed purple^ pepper Colour^ tan Cg" lour and dry-rofe Colcitr.

Blue and yellow mixt together compofe a yellow-green, fpring- green, graf-green, laurel-green, hroxun- green, dcrk-grecn ; as well as fea-green, parrct-green, cabbage green. Sic. thefe three laft Colours are to be Isfs boil'd than the reft. This is to be noted, that as to green there is no ingredient or drug in nature that will dye itj but the fluffs are dyed twice, firft in blue then in yellow. Blue and brown. Thefe two Colours are never mix'd alone, but with the addition of red, ekhci of rr.adder or cochineal, they form feveral Colours. Red and Yellow. All the (hades compcs'd of thefe two Co- lours^ zs gold-yelloz'j, aurora, marygold, orange, nacarat, granat- flower, fiame- colour, &c. are made w^'xih yellow and red of madder ; fcarlet being lefs proper as well as too dear. Red and Brown. Of thefe two Colours are form'd cinnamon colour, chefiut, musk, bear's hair, and even purple if the red be that of madder. Yellow and Brown. The Colours form'd from thefe two are all the fhades of feuille mort and hairjColours. But this may be taken notice of, that though it be faid, that there are no Colours or (hades made from fuch and fich mix- tures, it is not meant, that none can be made, but that they are more eanlv form'd from a mixture of other Colours.

COLOURING in Painting. The manner of applying and condudting the colours of a pKt^ure , or it is tl^,e picture of lights and fiiadows form'd by the various colours, emplo) 'd in Paint^ The Colouring is one of the principal branches in Painting. M. Felihien divides the painter's art into thrve parts, the difign, the compglitioii and the Calcuring. M 2 The COL The Colouring ftrikes the mofl-, but among maflers k always gives place to the defign. M. de Piles obferves, that the word Colouring in its confin'd fenfe, is chiefly applicable to a hiflory piece, fcarce at all to a landfcape. He adds, that the term Colouring relates more im- mediately to the carnations, than any thing t\(Q, The Colouring in its general fenfe, takes in what relates to the nature and union of colours ; their agreement or antipathy ; bow to u^e. them to advantage in light and fliadow, fo as to fhevv a relievo in the figures, and a finking of the ground. What relates to the aerial perfpcdlive, z. e. the diminution of colours, by means of the interpofition of air ; the various actions and cir- cum fiances of the luminary and the medium; the different lights both of the bodies illuminating, and illuminated; their reflec- tion?, fliadows, different views, either with refpetl to the po- fitioM of the eye or the objeiSl. What produces the ftrength, fiercenefs, fweetnefs, ^c. in Paintings well cohur'd is the various manners of Colouring both in figures, landfcapes, ^c. The doarine of COLOURING is compriz' d under the fol- lowing Rules. Colours are confidered either in refpedl of their ufe or their {economy and difpofjion. I . In rejpeSi to their ufe. They are us'd either in oil or wa- ter, thofe jn oil again, are either confidered with a view, either to their preparation or application. In the preparation of oil colours, care muft be taken that they be ground fine ; that in putting them, on the pallet, thofe which will not dry of themfelves be mix'd witii drying oil or other ingredients of a drying quality, and that the ttng'd colours be mix'd in as fmall quantities as poflrble. For their application, it is confider'd either in refpe£l: to the kinds of painting in works of various colours, or in tliofe of one fingle colour. For the firfl: in the larger piec.es, the colours are either laid en full, fo as they may be impafted, or incorporated together, which makes them hold the more firmly. Or elfe, the moic agreeable ones are mixt, which dry too hard and too haftily, with a little colour, and the cleareft of the oil ; but in both cafes the colours are to be laid on ilrong at firff, it being eafy to weaken thofe that are to be thruft back, and to heighten the others; the touches to be bold by the condu61; of a free and fteady pencil, that the work may appear the moft finifii'd at a proper diftance, and the figures animated with life and fpirit. COL As to glaz'J colours, care is to be taken that the under colour" be painted ftrong, and that it be a body colour and laid finooth. In finirn'd works which are to be view'd near at hand, they proceed, either by applying each colour in its place, prefcrving their purity without fretting or tormenting them, but fwcetly foftening all their extremities; or by filling up all the great parts with one fingle colour, and laying the other colours which are to form the little things upon it, which is the more expeditious way, but the more apt to decay. For the fecond, the kinds of pi£tures in one colour are two, viz. camieux, where the degradations of colours of objeils afar off, are ufually manag'd by lights, as with crayons and lajfo relievo ; which is an imitation of fculpture of whatfoever matter and colour, in both thefe the colours are wrought dry. See CAiMIEUX. As for ivater colours, they are wrought various ways, viz.. in dijhinpcr, where the colours are prepared in fize, which me- thod is us'd on all kinds of matter, mfrefco or painting on frefh mortar; where the Colour :t?g muft be quick, that the matter dry not, and with much care and neatnefs, laying each colour in its place, and interm.ingling them by parcels. In (jgouache, where the colours are mixt with gum, and the percil dragg'd as in paintings and wafhings. In miniature^ for fmall and delicate works, where the colours are to be very fine and clean, mixt with gums and v/rought ia dots or points. But in all the kinds of painting both in oil znd di/lemper, efpe- cially the latter, care muft be taken that the defign be fix'd, and all the parts mark'd out, before any colours be apply'd. But the fecond part of Colouring, or the ceconomy and dif- penfing thereof in painting?, regard is had, either firft to the quality of the colours, to appropriate them according to their va- lue and agreement, or fecondly, to their effect in the union and ceconomy of the work. As to the firft, it muft beobferv'd, thztzvhite reprefents light, and gives the brisknefs and heightning ; oa the contrary, llcjck like darknefs obfcures and effaces the objetls; again, l^lack fets off the light parts, and by that they ferve each other to loofen the objects. A proper choice is to be made of colours, and the too much charg'd manner is to be avoided, both in carnatio/is, where red colours are not to beaffeded, as rather refembling thefiefh whea flead than the skin; znd zWhxight glot(;ing colours, the skin, how delicate foever, being of a down-colour. In the drapery, where the painter has his whole ftock of co' iours to chufe out of to procure a good effed, and in. the land- M 3 fcape COL fcape to difpofe of thofe colours near one another, which mu- tually affid and raife each othei'^i force and brisknefs ; as red and grecn^ yellow and blue. To manage them fo, as that they be accommodated to the cfFedls of the great parts of light and colour, that the ftrong co- lours lead to the fof: ones, and make them more look'd at ; bringing them forwards or keeping them back according to the fituation and degree of force requir'd. As to the effeSls of colours, they either have relation to the union or the oeconomy ; with refpedt to the firft, care muft be taken, that they be laid fo as to be fweetly united under the brisknefs of fome principal one ; that they participate of the pre^ vailing light of the piece, and that they partake of each other by the communication of light, and the help of rcfledlion. As for the oeconomy in managing their degree?, regard is to be had to the contrnjl or oppofiiion intervening in the union of the colo!'rs\ that by a fweet interruption, the brisknefs which otherv/ife fades and paih, may be rais'd to the harmony which makes the variety o{ colours agree; fupplying and fuftaining the weaknefs of fome, by the flrength of others, neglecting fome places to ferve as a bafis or repofe to the fight, and to enhance thofe, which are to prevail through the piece. As to the degradatkii, v.'here the better to proportion the co- lours that fall behind, fome of the fame kind are to be preferv'd in their purity, as a llandard for thofe carry 'd afar off to becom- par'd by, in order to j'-iltify the diminution ; regard being always had to the quality of the air, which when loaded with vapours, weaken the colours more than when clear. As to the f.itiaiicn of the cclours, in this, care muft be taken, that the purelt and the ftrongelt be plac'd before or in the front of the piece, and that the compound ones, which are to appear at a diftance, be kept back by their force ; the glaz'd colours particularly to be Ub'd in the firft rank. Laflly, as to the exprejjlon of the fubje£l, and the nature of the matters c r ftuffs, whether (bining or dull, opake or tranfparent, poiifl^'d or rough. COLOURING. Colours, fays the ingenious Mr. Richard^ fan, are to the eye, what founds are to the ear, taftes to the palate, or any other objects of our fenfes, are to thofe fenfes ; snd accordingly, an eye that is delicate takes in proportionable pleafure from beautiful ones, and is as much offended with their contraries. Good Colourwg therefore in a pi£lure, is of confecjuence, not only as it is a truer reprefentation of nature, where every thing is beautiful in its kind, but as adminiftring a good degree of plea- fure to the fenfe, Tb4 COL The Colouring of a p'lSiure mujl be varied according to the fubjed, the time and place. li the fubjeft be grave, melancholy or terrible, the general teint of the Colouring muft incline to brown., black or red and gloomy ; but you muft be gay and pleafant in fubjecEls of joy and triumph. See EXPRESSION. Morning, noon, evening, night, fun-fhine, wet or cloudy weather, influences the colours of things, and if the fcene of the pi(fture be a room, open air, partly open and partly inclos'd, the Colouring muft be accord in2;Iy. The diftance alfo alters the Colouring., becaufe of the medium of air, through which every thing is ften, which being blue, the more remote any object is, the more it muft partake of that colour, and of confequence mutt have lefs force or ftrength ; the ground therefore, or whatfoever is behind a figure (for ex- ample) muft not be {o ftrong, as that figure is, nor any of its parts which round off, as thofe that come nearer to the eye ; and that not only for the reafon already given, but becaufe there will always be reflt£tians ftronger or weaker, that will di- minifli the force of the fhadows, which reflexions (by the way) mutt partake of the colours of thofe things from whence they are produc'd. Any of the feveral fpecies of colours may be as beautiful in their kinds as the others, but one kind is more fo than another, as having more variety, and confifting of colours more pleafing in their own nature; in which I armony and agreement of one tin^ with another^ the goodncfs of Colouring conftjU. To fhew the beauty of variety, I will inftance in a gelder- rofe^ which is white, but having many leaves one under another, and lying hollow, fo as to be feen through in fome places, which occafions feveral tin£ts of light and fhadow ; and together with thefe fome of the leaves having a greenifh tincl, all together produces that variety, which gives a beauty not to be found in this paper, though it is white, nor in the infide of an egg-fliell though whiter, nor any other white object, that has not that variety. And this is the cafe, though this flower be feen in a room, in gloomy or wet weather ; but let it be expos'd to the open air, when the sky is ferene, the blue that thofe leaves, or parts of leaves that lie open to it will receive, together with the reflec- tions that then will alfo happen to ftrike upon it, will give a great addition to its beauty. But let the fun-beams touch up its leaves, where they can reach with their fine yellowilh tmdl, the other retaining their sky blue, together with the ftiadows and brisk reflections it will then receive, and then you will fee what a perfedion of beauty M 4 .t COL k wHl hare ; not only becaufe the colours are more p'eafant in tbemfelves, but there is greater variety. A sky entire! J blue would have lefs beauty than it has, being always varied towards the horizon, and by the fun- beams, whether riiing, fettinz, or in its progrefs ; but neither has it that beauty, as when more varied with clouds, xlng'd with yellow, wliitE, purple, cr'-. A piece of filk or doth, hung or laid fiat, has not the beauty, though rhe colour of it be pleaiing, as when flung into folds; nay, a piece of file that has little beauty in itfelf, may be much improv'd only by being plnk'd, water'd or quilted ; the reafoa is, in thefe cafes there arifes a variety produc'd by lights, fhad^ z^d re5e<^ons. There are certain colours Ids agreeable th^an others, as a brick •wall for example ; yet when the fun ftrikes upon one part of it, and the sky tinges another part of it, and the (hadows and re- fledicns the reft, this variety Ihall give even that a degree of beauty. Perfec: bbck and white are difagreeable, for which reafon, a painier fn-y^ld h-^tak ihzjt extremes cf czhzirs^ that there may he a voarmtb and nullyjiTuJs in his vxrk ; let him (injiejb efpeciallj) rememtrr to Gv:.:d the chalk, the brick and the charcoal, and think cf a pearl and a ripe peach. But it is not enough, that the colours in themfelves are beau- tiful finzly, and that there is variety, they muji he fet by cne an- ciber^ fj a- to he mzdualty affijiant to each ether \ and this not only in the obje<^ painted, but in the ground, and whatfoever comes into theccmpofition, fo as that every part, and the whole tc^ether may hiVe a pleafing effe<3 to the eye, fuch a harmony to it as a good piece of muhck has to the ear j but for which no certain ruies can be given, no more than for that, except in fon:£ {tv general cafes, which are very obvious, and need not therefore be mentioned here. The beft that can be done, is to advife one who would know the beauty of Cclsjcring, to chferoe nature, and how the heji co~ huriji: huve imiiaied her. What a lightnef , thiimefs and tranfparer.cy, what a warmth, deannefs and delicacy, is to be fecn in life and good pi(9:jres ? He tr.at would be a good colourift himfelf, muft moreover practife m-ch, and for a ccnfiderable time accuftom him- felf to fee well coloured pi<^ures only ; but even this will be in vain, uniefs he has a good eye, in the {eT,{t, as one is faid ta have a good ear for mufick ; he muft not only fee well, but have a particular delicacy with relation to the beauty of co- joyrs, zad. the infinite ?&iiety of Uadts* The COL The Venetian^ Lcmbard and Flemijb fcbools have exceli'd in Colouring ; the Florentine and Rsman in dif.gn ; the Bohgmfe mafters in both ; but not to the degree generaliy as either of the other. Correggio, Titian, Paolo Vetsnefe, Ruben: and Fan Dyck have been admirable colourifts ; the latter, in his beft things, has fol- lowed nafjre extremely clofe. Rafcclui Colouring, efpecially in his dadows, is blackifh. This was occafion'd by the ufe of a fort of printer's black, and which has chang'd its tind, though it was warm and glowing at firfl, upon which account he was fond of it, though be was advis'd what would be the confequence. However, by the vaft progrefs he made in Cslsuring, after he appl) 'd himfelf to it, 'tis judg'd he would in this part of painting alfo have exceli'd as in the others. Here would have been a double prodigy ! Since no one man has ever pofTefs'd even Colouring and Defigningy to that or any verv confiderable degree. Though the Carioom tctz fome of the laflof his works, itmuft be confefs'd the Colouring of them is not equal to the drawins; but at the fame time, neither can it be deny'd, but that he that painted thofe could colour well, and would have coiour'd better. It muft be confidered, they were made for patterns for ta- peftry, not profefs'd pi^res, and painted not in oil, but in di- ftemper ; if therefore one fees not the warmth and mellownef*, and delicacy of Colouring, which is to be found in Corrrggl:^ Titian or Rubens, it may bs in a meafure fairly impuied to thefe cau fes. A judicious painter has other confiderations relating to the Cchuring, when he makes patterns for tapeftry to be beighten'd with gold and filver, than when he paints a p:<9:ure, without any fach view ; nor can a fort of drynefs and harihnefs be avoid- ed in d'jlempcr upon paper. Befides, time hath apparently chang'd fome of the colours. In a word, the tout enfemhle of the colours is agreeable and roble, and the parts of it are in general extremely, though not fuperlatively good. I will only add one obfen'ation here concerning the colours of the draperies of the Apoftles, which are alwavs the fame in all the Cartoons; only St. Peter, when he is a hiberman, has not his large apollolical drapery on. This Apoftle when drefs'd wears a yellow drapery over his blue coat, St. John a red one over a green, (o does St. Paul, which is alfo the fame which he wears in the fimcus S:. Cuiiia^ which was painted near ten years before. COL The various forms and degrees of COLOURING. There are four various forms or degrees of Colourings viz. 1. Of infants or children. 2. Of virgins or fair v/omen. 3. Naked bodies. 4. Old or aged bodies. 1, Infants or young children are to be painted of a foft and de- licate complexion, the skin and ears of a ruddy and pleafant co- lour, almoft tranfparent. This may be done with white-lead^ lake^ and a little red- lead, fhadowing it thin, faint and foft, letting the cheeks, lips, cbin^ fingers, knees and toes be more ruddy than the other parts ; making all their linen very fine, thin and tranfparent or perfpicuous, with ftrong touches in the thickeft folds. 2, Virgins and fair women are as curioufly to be exprefs'd as the former, but their mufcles ought to appear more plainly ; their ftiapes more perfect, and their fliadows to be of a whitifti yellow, bluifh, and in fome places almoll purple. But the moil perfect and exquifite diredion, is the life, which ought rather to be followed, than any thing delivered by rule. For the (hadows here, mix white with pink, and indigo and ijuhite, and in fome places lake with a little indigo and white. As for womeiis bodies, viz, fuch as are naked, they are to be reprefented foft, round, plump, gentle and tender, and with- ©ut mufcles. On the contrary the bodies of tnen are to he reprefented Jirong^ flurdy, flout and vigorous, with the mufcles exactly placed and ftrong \ which to do with judgment and underjianding, requires time, ftudy and knowledge in anatomy. 3. Naked bodies are to be painted flrong, lively and accu- rate, exa6lly matching the refpe^live pairs of mufcles and nerves, fixing each artery in its due and proper place, giving each limb its proper motion, form and fituation, with its true and natu- ral colour ; all which to do well, may be the ftudy and pradice of almoft ones whole life. 4. Old or aged bodies ought to be eminent for exa£l and cu- rious fliadows, which may be made o^ pink, lake, and ivory black, which make very proper fliadows in appearance, like the wrinkles and furrows of the face and hands in extreme old age. Let the eyes be dark, the afpedl melancholy, and hair white (or elfe the pate bald) and all the remarks of antiquity or age be Mtry apparent. Pink mixt with lake and red-lead make an excellent fliadow for the bodies o^ old 7nen; but for the extremeft or deepeft flia- dowings, either in face or body, mix lake and ivory black, which will COL will make an excellent deep fliadow, and will be very ufeful in expreffing the feveral furrows and wrinkles in the face and hands of very old people, with their dark eyes and melancholy afpeds. But notwithftanding all the foregoing rules, the pofture or form of ftanding, and being, either of the whole body or any of its parts, ought to be diligently obfeiv'd, that the life may be imitated. The making original COLOURS. To make white Lead. Put into an earthen pot or crucible feveral plates of fine Lead, cover them with white wine vinegar, covering the top of the pot clofe with clay ; then bury it in a cellar for feven or eight weeks, and you will have a good white lead upon the plates, which wipe ofF. To make Verdegreafe. Hang plates of copper over the fumes of aqua forth or fpirit of nitre, or dip them in the fame or in vinegar. To make an Emerald Colour. Powder verdegreafe very fine, temper it with varnifh, and lay it upon a ground of liquid filver buinifht, and it will look like a fair Emerald. To })take a Ruby Colour. Mix varnifh with Florence lake, ami it will make a very fair colour. To make a Sapphire Colour. Mix verdegreafe and ultramarine with varnijhy and it will make a glorious Sapphire. To make a Crlmfon Velvet. Mix turnfole wiih Indian lake (well ground with gum and fugar candy) lay it on full, and when it is wet, wipe away the colour with a dry pencil, where you would have the heightening of the Crlmfon Velvet appear, and the flronger reflection will be well exprefs'd. To make a Silver black. Take fine Silver filings of plates, and diflblve them in fpirit of nitre or aqua forth, and evaporate to drinefs, or precipitate cum oleo fulphurh or fait water, and you will have a fnow white precipitate, which mixt with water makes the beft black in the world, for dying all manner of hair, bones, horns, woods, metals, ^c. To make a Murrey or Amethyfi. This is made by grinding Indian lake with gum arablck water only. To make Red or Ruby for limning. This alfo is made of In- dian lake (which breaks of a fcarlet colour) ground with gum water and fugar candy. To make azure Blue or Sapphire. You may make this of ul- tramarine of Venice (which is the befl) the beft blue f malt, or blue bice ground with gum water only ; alfo good Ihadowing blues may be made of Indigo, fiory and lltmofc, all which need no wafhing, nor lltmofe no grinding, but only to be infus'd in a Ih.lvium of foap-afhcs. COL To make a Green or Emerald. Make it of cedar green inftead rf which take green bice to draw with ; pink is good alfo for landfcapes, mix'd with bice aflies, as alfo with mafticote and cerufs. To make a Yellow or Topaz. Take mafticote, of which there are divers forts, viz. deeper and paler. A\(o yelloiu oker may do for want of better, fliadow mafticote with yellow oker, deepen it with oker de luce. To make ultramarine. Take lapis lazuli of the deepeft colour (having few veins of gold upon it) put it into a crucible, cover it clofe, heat it red hot, then quench it in urine, vinegar or wa- ter, in an earthen pot with a lid ; dry it well, then nip ofFthe hard, gray and whiteft part from it, with a pair of pincers; then grind the remainder with honey'd water, as fine as may be, and dry it for ufe. The lioney'd water is made by boiling two fpoonfuls of honey in a quart of water. The life and nature of dry COLOURS. 1. Blue bice is the moft excellent blue next to ultramarine^ which is too good to v/afn withal, and therefore I leave it out here, and put in blue hice^ which will very well {^xvt. inftead of it j and indeed, you may leave out both, and ufe fmalt in- ftead of them, but that it will not work as well as hice. Bice is too good to ufe upon all occafions, but when you intend to beftow fdme coft and pains upon a piece ; otherwife you may ufe no other bkie in your work than blue verditer^ with which you may make a very good ftiift, without any other blue, I mean in any ordinary work, 2. Indigo is a dark blue which is ufed principally to fhadow v/ith upon your other blue ; indigo and yellow berries mixt toge- ther make a dark green, to fliadow other greens in the darkeft places. 3. Blue verditcr is a very bright pleafant blue, and the eafieft to work with in water ; it is fomewhat inclining to a green, and being mix'd with yellow berries it makes a good green ; this is moft ufed. 4. Verdegrcafe is a good green, but fubject to decay ; when it is dry u^on the paper, it will be of a lighter colour than it was when you lay'd it firfl on ; therefore, to preferve it from that fault, put fome fap-green amongft it to diflblve in it, and it will make it keep its colour. There is diftill'd verdegreafe to be bought at the colour-fhops, that is a far better green than the other, but it is fomewhat dearer, and the other will ferve ijiftead of it. 5. VerdlUr*: COL 5. Verditer-green is a light green, fcldom ufed In any thing but in colouring landfcapes, and thofe places that fliould ihew afar off; and it is good for fuch a purpofe, becaufe it is fomewhat inclining to a blue ; but you may make fliift to do any thing well enough without it j for a little blue verditer^ mixed with copper green and a little -Mhite, make juft fuch another green. 6. Sap Green is a dark, dirty green, and never ufed but to fhadow other greens in the darkelt places, or elfe to lay upon fome dark ground behind a pidture which requires to be colour- ed with a dark green ; but you may make fliift well enough with- out this green, for indigo and yelloiv-berries make juft fuch an- other colour. 7. Copper Green is an excellent tranfparent green, of a (hin- ing nature, if it be thickened in the fun, or upon a gentle fire; and it is moft ufed of any green in wafhing, efpecially in colour- ing of the grafs, ground, or trees, for it is a moft perfect grafa green. 8. Vermilion is the pcrfed^eft fcarlet colour; you need not grind it nor wafh it ; it is fine enough of it felf, only temper it with your finger in a gallipot, or cyfter-fhell, with gum-wa- ter, and it will be ready for ufe ; if you put a little yellow ber- ries amongft it, it will make the brighter colour ; this is princi- pally ufed for garments. 9. Lake is an excellent crimfon colour ; with it you may flia- dow vermilion, or your yellow garments in the darkeft places; with it you may make a sky colour, being mixed only with white ; with it you may make a flefli colour, fometimes mixed together with white and a little red -lead ; it is an excellent co- lour itfelf, to colour garments or the like. Indian lake is the beft lake, but too good to be ufed to wafh prints with, unlefs you intend to beftow great curiofity upon your works; but the beft fort of ordinary lake will ferve well enough for ordinary ufes, but that alfo will be fomewhat more coftly. Therefore, inftead thereof, you may ufe red ink thickened upon the fire, and it will ferve very well for your purpofe, and better than lake, unkfs it be very good. Note^ if you would make a light sky colour of your red ink, or if you would mix it amongft your fiefh colour, you muft not thicken it ; you ftiould rather chufe to fhadow your vermilion with S-paniJh brown, than thick red ink, which will ferve well for that purpofe, but is not altogether fo bright a colour and clean. 10. Red-lead is the neareft to an orange colour, and putting a little yellow berries into fome of if, will make a perfect orange colour 3 but ii you mean to make flefh colour of it, you muft put COL put no yellow, but only when you would make an orange co- Jour. This colour is ufed in colouring of buildings, or high-ways in landfcape, being mixed with a little white. Alfo it is the only bright colour to fhadow yellow garments with, to make them (hew like changeable tafFety. It is good alfo to colour any light ground in a picture, taking only the thin water of it, and fo for feveral other ufes, as you fhall fee occafion for it. 1 1 . Yellow berries are moft ufed in wafiiing of all other co- lours ; they are bright and tranfparent, fit for all ufes, and will be fufficient, without the ufe of any other yellow. 1 2. Saffron is a deep yellow, if you let it (land a pretty while ; it is good principally to fhadow yellow berries with inftead of led-lead, and it is fomewhat of a brighter fhadow ; but you may make fhift well enough without this colour, for red-lead and yellow berries make jufl fuch another colour. 13. Majlicote is a light yellow juft like yellow berries and white, and therefore you may make fhift well enough without it, only for faving you a labour to mix your yellow berries with white, when you have occafion for a light yellow, which you may fometimes make ufe of to colour a light ground in a pi6ture, and then fhadow it with the water of burnt umber or red-lead^ that is the thinneft part of the colour. 14. Cerufs is the belt white, if it be good and finely ground, or for want of it, white lead picked : either of thefe will ferve well enough, for either of them being mingled with another colour make it lighter, and the more you put, the lighter they will be. 15. Spanijh broivn is a dirty brown colour, but of no great life to colour any garment with, unlefs it be an old man's gown ; to fhadow vermil'ien^ or to lay upon any dark ground behind a picture , or to fhadow yellow berries in the darkefl places, when you want lake or thin red ink. 16. It is the befl and brighteft colour, when it is burnt in the fire till it be red hot; tho' if you would colour any hare, horfe, dog, or the like, you muft not burn it ; but for other ufes, it is belt when it is burnt ; for inftance, to colour any wooden pof^, bodies of trees, or any thing elfe of wood, or any dark ground in a pi6ture. It is not to be ufed about any garments, unlefs you would colour many old mens gowns or caps flanding toge- ther, becaufe they muft not be all of one colour ; therefore, for diflin(Sion and variety's fake, you may ufe umber unburnt for feme of them. 17. Printer* s black is mofl ufed, becaufe it is eafiefl to be had, and ferves very well in wafhing. t N0U9 COM NotSyYou muft not put any black amongft your colours to make them dark, for it will make them dirty ; neither fhould you (hadow any colour with bhck , unlefs it be Spanijh brown, when you would colour an old man's gown that requires to be done of a fad colour ; for whatfoever is fhadowed with black, will look black, and not bright, fair and beautiful. I 8. Ivory burnty or for want of that, bone burnt is the black- eft black, and is thus made ; take ivorv, or for want of it, fomc white bone, and put it into the fire till it be thoroughly burned ; then take it out, and let it cool ; flit it, take out the blackeft of it in the middle, and grind it for your ufc. COMELINESS is reprefented in painting, i^c. by a beauti- ful nymph of a graceful afpecl in changeable taffety, on her gir- dle is embroidered a Cupid and Merc loy's rod, holding the corn marigold in her right hand, and the bird wagtail in her left. Every fair face is not comely. Fultu pulcbro tnagh quam ve- mifioy Graccfuinefs to beauty is like fait to meat, gives it a re- lifli ; the girdle of Venus was of needle-work, and had the vir- tue to get love ; the wagtail, becaufe it was thought to have in it an innate power to excite amorous thoughts, and they fay a man lyngem habet^ who is fo graceful that he charms. COMMERCE is reprefented in painting, l^^c. by a man with his fore finger pointing to two miJl-ftones ftanding by him j a ftork on his right arm, and a buck at his feet. The two mill-ftones denote aftion and commerce, for being double, the one can do nothing without the other, nor grind any corn alone. The ftorks help one another in flying, and the bucks in fwimming. COMMONWEALTH Is reprefented in painting by a la- dy refembling Minerva^ holding an olive branch in one hand, and a fnield ; and in the other a javelin, with a helmet on her head. Her deportment, like Minerva^ (hews that wifdom is the prin- ciple of good government \ the helmet, that the republick ought to be well fortified and fccured from foreign force. The olive and dart, that peace and war are both beneficial to the Com- monwealth ; war, becaufe by experience valour is attained 5 peace, becaufe by leifure prudence to govern is acquired. COMPASSION. The lively attention to the misfortunes of others, which is call'd compaflion, caufes the eye-brows to fmk towards the middle of the forehead ; the eye-ball to be fixt upon the objed ; the fides of the noftirils next the nofe to be a little elevated, making wrinkles in the cheeks ; the mouch to be open ; the upper lip to be lifted up and thruft forwards ; the mufcles and all the parts of the face finking down and turning towards COM towards the obje£t which caufes the pafllon. And by thefe ex- preflions it is to be reprefented in drawing. See the plate. COMPASSION is reprefented in painting, l^c. by a woman holding a pelican's neft in her left hand, who piercing her breaft, feems to fuckle her young ones with her blood ; {he ex- tends her hand in a compailionate manner to beftow charity on the indigent. The pelican is a true emblem of compaflion, for flie is faid never to ftir from her young , and when her nouriftiment fails, ihe feeds them v/ith her own blood. Her extended hand de- notes her readincfs to relieve with her own fubftance. COMPLAINT to GOD is reprefented in painting, b'c. by a woman clothed in a white veil, of a forrowful countenance, looking up to heaven ; laying one hand upon her breaft, {hew- ing the other bitten by ferpents. Her cheeks bathed in tears, demonftrate her complaint ; her looks, that {lie direfts her complaint to God j her hands denote the reafon of her complaint to be fome offence, fignified by the ferpents; her white raiment and hand upon her brea{l denote innocence. COMPOSITION Is putting together for the advantage of the whole, what {hall be judged proper to be the feveral parts of a pidure ; either as being effential to it, or becaufe they are thought neceffary for the common benefit : And moreover, the determination of the painter, as to certain attitudes and colours, which are otherwife indifferent. The Compofition of a pidture is of va{l confequence to the goodnefs of it ; 'tis what fir{l of all prefents itfelf to the eye, and prejudices us in favour of, or with an averfion to it ; 'tis this that directs us to the ideas that are to be conveyed by the painter, and in what order ; and the eye is delighted with the harmony at the fame time as the underftanding is improved. Whereas this being ill, tho' the feveral parts are fine, the picture is trouble- fome to look upon, and like a book, in which are many good thoughts, but flung in confufedly, and without method. Every picture {hould be fo contriv'd, as that at a di{lance, ■when one cannot difcern what figures there are, or what they are doing, it {hould appear to be compofed of maffes, light and dark ; the latter of which ferve as repofes to the eye. The forms of thefe maffes muft be agreeable, of whatfoever they confi{l, ground, trees, draperies, figures, ^6-. and the whole to- gether fhould be fweet and delightful, lovely {hapes and colours, without a name ; of which there is an infinite variety. And 'tis not enough that there be great-mafl'es j they mufl be fubdivided into leffer parts, or they will appear heavy and dif- agree^ble. to vT^ CaniJia/ft Dr'/M/i^n. Ff^f.- J7J ^pO c COM agreeable. Thus, tho' there is evidently a broad light (for ex- ample) in a piece of filk, when covering a whole figure, or a limb, there may be lefler folds, breakings, flickerings, and reflec- tions, and the great mafs yet evidently preferv'd. Sometimes one mafs of light is upon a dark ground, and then the extremities of the light muft not be too near the edges of the picture, and its greateft Itrength mufl be toward the centre ; as in the defcent from the crofs, and the dead Chrift, both of Reubens^ and of both which there are prints, one by Vojlerman and the other by Pontius. Mr. Rlchardfon has a painting of the Holy Family by Reubens of this ftru(Slure ; where, becaufe the mafs of light in one part, would elfe have gone ofF too abruptly, and have made a lefs pleafing figure, he has fet the foot of S. Elizabeth on a little ftool : here the light catches, and fpreads the mafs fo as to have the defired effedl. Such another artifice Rafaelle has ufed in a madonna, of which Mr. Richardfon has a copy ; he has brought in a kind of an ornament to a chair for no other end (as may be imagined) but to form the mafs agreeably. Van Dyke^ that he might keep his principal light near the middle of his pidure, and to advantage the body which he feems to have intended to exert himfelf in, has even kept the head fombrous in an ecce homo^ which Mr. Richardfon has of his, and makes the whole have a fine effeft. The fame author fays, he has many times obferv'd with a great deal ofpleafure the admirable compofition (befides the other excellencies) of a fruit-piece oi Michael Angela CompadogUo. The principal light is near the centre (not exadtly there, for thofe re- gularities have an ill-efFe£l:,) and the tranfition from thence, and from one thing to another, to the extremities of the pidlure all round, is very e.*fy and delightful ; in which he has employed fine artifices by leaves, twigs, little touches of lights ftriking ad- vantageoufly, and the like. So that there is not a ftroke in the pidture without its meaning ; and the whole, tho' very bright, and confiiting of a great many parts, has a wonderful harmony and repofe. Sometimes the flruflure of a piflure, or the tout-cnfemble of its form, (hall refemble dark clouds on a light ground ; as in two aflumptions of the Virgin by Bolfwert, after Rubens. Le Brun. in a ceiling of the fame fubjedl, grav'd by young Simconneau, has put a group of angels, which almoft hide the cloudy voi- iure of the Virgin ; but this mafs is of too regular and heavy a Piape. There are inftances where two mafies, a light and a dark one, divide the picture, each poflefling one fide. Of this fort is one done by RubenSy and as fine a compofition as can be feen j Vol. I, N th? COM the mafTes are fo well rounded, the principal light being near the middle of the bright one, and the other having fubordinate lights upon it, fo as to connect, but not to confouud it with the reft ; and they are in agreeable fhapes, and melting into one an- other, but neverthelefs fufficiently determined. Very commonly a pi6lure coniifts of a mafs of light, and an- other of (hadow upon a ground of a middle tin<5l. And fome- times 'tis compofed of a mafs of dark at the bottom, another lighter above that, and another for the upper part ftill lighter ; (as ufually in a landfcape) fometimes the dark mafs employs one fide of the pidure alfo. As a certain copy after Paolo Vera- nefe^ where is a large group of figures, the principal ones of the ftory compofe this lower brown mafs ; architecture, the fecond ; more buildings with figures and the sky, the third ; but moft commonly in pi«£lures of three mafles, the fecond is the place of the principal figures. Of fuch confequence are thefe agreeable mafles in a picture, that for the fake of them, vi^hat is lefs material in a piClure, muft be difpens'd with when both cannot be had. As the prin- cipal figure and action muft be diftinguifti'd, thofe limbs of a figure that are chiefly employed, ought to be made confpi- cuous. As the tout-enfemhle of a picture muft be beautiful in its maf- fes, fo muft it be as to its colours. And as what is principal • muft be (generally fpeaking) the moft confpicuous, the predomi- nant colours of that fliould be diffus'd throughout the whole. This Rafaelle has remarkably obferv'd in the cartoon of St. Paul preaching ; his drapery is red and green, and thefe colours are fcatter'd everywhere, but judicioufly; for fubordinate colours, as well as fubordinate lights, feive to foften and fupport the prin- cipal ones, which otherwife would appear as fpots, and confe- quently be offenfive. And when the fubjeCt does not necelTarily require a due va- riety or beauty of tinCts ; or perhaps the picture, when thought to be finifh'd, is found to vi^ant fomething of this kind, a few red, or yellow leaves of trees, flowers of whatever colour, in | fhort, any thing otherwife inaiffcrent may be flung in very ad- vantageoufly. In a figure, and every part of a figure, and indeed in every thing elfe, there is one part which muft have a peculiar force, and be manifeftly diftinguiihed from the reft, all the other parts I of which muft alfo have a due fubordination to it, and to one another. The fame muft be obferv'd in the compofition of an | entire picture; and this principal, diftinguifh'd part ought' (generally fpeaking) to be the piace of the principal figure and a which will make it more foft and gentle. Be fure to mix cerufi with all the other colours and (hadows whatever. The temperatures for greens are made of pini and biu, and tnajl'icot and fmalt, and majiicot and indigo^ with which colours you may make them lighter or deeper as you pleafe, remem- bring that where you are to temper firm colours, as umber^ oker, indigo, &c. you are to take the lefs plaijier of Paris ; and where the colours are loofe there bind them ftronger and fafter, by adding more plai/ier of Paris. Of the making of CRAYONS for dry colouring. The ufe of Crayons for dry colours is fo neceflary in taking of views and profpefts, and there are fo few Crayons that are good of the fort, that I think the way of making them a neceflary article to be known to every one, who is a lover of drawing and painting. WHITE. As for white we have no occafion of any other, than that of vjhite foft chalk, which fliould be faw'd into lengths of an inch and half or two inches, [There are little faws made on purpofe for fuch ufes about four inches long and very thin.J When you have fawed out your Crayons of chalk, which fhould be at moft a quarter of an inch thick, round ofFthe corners with a penknife, and point them by drawing your penknife .'pwards from the place where the point is to be. You ought to have a dozen or two of thefe to lie in a little cafe by themfelves, or they will be difcolour'd by the other colours. YELLOW C R A YELLOW PASTILS, or CRAYONS. Yellows come next, which fhould bs divided into four or five degrees of colour. ly? Yellow. Take fome grounds of ftarch and flower of brim- ftone, mix them well with a knife upon a polifti'd marble, fo that they produce the colour of ftraw, or a Yellow as will (hew itfelf faintly ; then pour a little milk to them, era little pale ale- wort, till the colour become like a pafte j then fpread the pafte on a fmooth piece of chalk, with a broad knife till it is about the third pait of an inch thick, and let it lye till 'tis half dry; then with a fharp knife cut it in lengths of an inch and a half, about the fourth part of an inch wide, and roll it thin between two little pieces of board, till they are round like a ftraw, and point them as I have dirccfled for the chalk. Ifyoupleafe you may ufe ground chalk inftead of grounds of ftarch. zd Yellow. It is made of yellow oker, ground well with fair water, and then dried and beat. Mix this with ground chalk, in fuch quantity as it will be a little deeper than the former colour, and mix them up with pale ale-wort, in which a little white fu- gar-candy may be diflblv'd j and make thefc Crayons as the former. 3^/ Yellow. Grind yellow oker with water, with aftoneand mujler, and when 'tis dry, beat it very fine, and make it into Pajiils or Crayons, with pale ale-wort, or fize made with glo- ver's leather, boil'd in water 'till it comes to a jelly; ufe it as before diiefted, and ro'l the Pajiils between two boards. j^th Yellow. Take Engltjh pink, grind it as the former with water, and when 'tis dry beat it fine, and mix it with a very little ground chalk, till 'tis deeper than the former colour ; then put to it fome wort of pale ale, and ftir all well together, and make it into Pajiils or Crayons^ by rolling in the foregoing man- ner. K,th Yellow. EngUJh pink is to be ground as the former, and to be made in Pajiils or Crayons^ by itfelf with pale ale- wort. tih Yellow. Dutch pink is to be us'd as the former, and mixt with pale ale-wort, or milk, and to be roU'd and dried. Tih Yellow. Orpiment is one of the moft poifonous colours that can be us'd ; however it is one of the moft beautiful fort, and is next to orange-colour. This muft have a little ground chalk mixt with it, well temper'd together, and made up with pale ale- wort, with a little gum-dragon diiTolv'd in it ; and roll them up into Pajiils, as you did the former. ORANGE-COLOURS. ly? Orange-Colour. Take yellow orpiment, mixt it with pale ale-wort, and when it is in pafte, roll it, and make it into Pajiils or Crayons, zd Orange- C R A 2, Orange-Colour. Take orpiment and red-lead, (letthered- kad be very finely ground in water, and dried) then mix a lit- tle of this with your orpiment, till you hav^e the colour you de- iire ; and putting in it fome ale-wort, wheiein feme gum dra- gon has been diflblv'd, make into a pafte, and roll it into Pajiih or Crayons, T,d. Orange-Colour. Take Engl'ijh pink, grind it well, and put to it as much vermilion as will make it of the colour you de« fire ; mix thefe up with ale- wort, that has been boil'd till 'tis more glutinous than ordinary, and make it into Pajlils or Crayons as before. ^th Orange-Colour. Take Englijh pink finely j.>-iound, and put to it as much red-lead, well ground, as will make it agree- able to your defign, mix thefe well with ale-wort boil'd to a thicknefs, and make them into Crayons. ^th Orange-Colour. Take fome Dutch pink, well ground, and mix it with fome red- lead finely powdered, to the colour you want j then with ale- wort or milk make it into a pafle, and make it into Pajlils as before. Notey In the mixture of thefe colours, obferve, that they have as many different (hades as pofTible. REDS. \Jl Red. Take red-lead, grind it well with water, then dr/ it and beat it to a fine powder, and put to it fome chalk or white-lead finely ground to brighten it; mix this with ale- wort, wherein a little gum-dragon has been boil'd, make it into a pafte, and roll ic mto Crayons. Of this your Pajlils fhould be made fome deeper, others paler, zd Red. Take red-lead, and grind it well with a marble and muiler, make it into a pafte with ale- wort, in which gum- dragon has been boil'd. T,d Red. Rcd-^ker wants no preparation, but fawing as di- redied for chalk, in the firft article. 4/-6 Red. Take vermilion, ground fine, and mix it with fome fine chalk, or white-lead, well pulveriz'd ; divide the com- pofition into three parts, and by adding more of the white to one than another, you may make three different colours ; then put ale- wort boil'd thick to each, and make them feverally into pafte, and then into Pajlils. ^th Red. Take vermilion, grind it well, and mix it with ale- wort, that has been boil'd to a thicknefs with gum- dragon, till it is a pafte, then roll it into Crayons or Pajlils. 6th Red. Take fome good lake, well ground with water upon a marble, and when 'tis well dried and powdered, divide it into three parcels, and mix with each as much chalk or white-lead ground fine, as will make them of different colours, work C R A work them feverally into pafte j then roll them into PaJliU or Crayons. 'jth Red. Take fine lake, and reduce it to as fine a powder as you can with water, and when *tis dry , and again finely powdered, mix it with ale- wort, and make it into a pafte, and roll it into Crayons. Sth Red. Take Indian red well ground with water, and dry it like the other colours; then mix it with ale- wort that has been boil'd to a thicknefs with gum-dragon. This alone will be a very ftrong colour ; but to make it of different fliades, you muft mix it with white, each parcel (o as to be fhades to one another ; then make 'em feverally into Pajiih. gtb Red. Take rofe-pink, and cut it into the fhape of Cray" 9nsy without any preparation. Carmine is too dear for them ; for twelve penny-worth would make but a fmall Crayon, PURPLES. I/? Purple. Take rofe-pink finely ground and powdered, mix it well with a little Sanders blue, till the powder appears of the colour you defire ; then make it into a pafte with ale-wort, thickned with gum-dragon, and roll it into Crayons. 2d Purple. Take lake finely ground and wafli'd, add to it as much blue bice as you think convenient to make it of a red- difli purple, and you (hould vary this in two or three manners, each lighter than the other ; in the lighter forts, put a fufficient quantity of chalk or white-lead ground fine, and mix them up with ale-wort boil'd to a thicknefs with gum-dragon j then roll them into paftils. 3^ Purple. Take fome lake well ground, and to it add as much Prujffian blue as will make it of the colour you intend ; mix thofe well together in different parcels, making fome more inclining to red than the others ; and to make the fainteft purple of them, add fome chalk ground at your difcretion, and make 'em feverally into pafte with ale-wort thickned by boiling ; then in- to Pajiils as before directed. BLUES. I/? Blue. Blue bice is the lighteft blue colour ufed, and muft be well ground with fair water on a fine marble, and when it is dry, reduce it again to a powder; then lay it in four parcels, and put to three of them, in different proportions, fome chalk or white- lead ground, fo that, when mixt, each may be lighter than the other ; mix thefe fcparately with ale- wort, thickened with fcraps of glover's leather ; and when they are made in a pafte to your mind, make them into paftils, and the fourth part of the blue bice muft be made up by it felf in the fame manner, zd BluCi C R A 2d Blue. Take verditer well ground on a fine marble, lay tt in four parcels, and mix one of them purely with a thin fizc, made of white glovers (hreds and ale- wort ; and the other three parts mix with feveral proportions of chalk or white-lead well ground, fo as to make fhades to one another ; make thefe into pafte with ale-wort, thickned with gum-dragon, and then into Crayons. id Blue. Take fome Prujffian blue well ground, and lay it in four parcels on your marble, and with three of them mix fome chalk or white-lead well ground to make them of different degrees of colour, and the fourth muft be alone. Make the three mixt colours into pafte with pale ale-wort boil'd till k thickens ; and the plain colour muft be made into a pafte with fome ale- wort boil'd, and thicken'd with white (havings of lea- ther from the glovers. Make all thefe into Pajlils. 4tth Blue. Take rock indigo well ground with water on a marble, dry it and powder it again j then divide it into parcels as before, and with two or three parts of them, mix different proportions of ground-chalk or white-lead ground, to make them deeper or paler ; and one part muft be the fimple colour. Put to the mixt colours fome ale- wort thickened with boiling, and mix them to paftes ; then make them into paftils. As for the plain indigo, mix it with ale-wort thickened by boiling with glover's Ihreds of white leather, then make it into Crayons. BLACKS. ijl Black. The black that is commonly ufed as a Crayon^ is charcoal cut into lengths ; the fofteft and beft is that made of willow. Have at leaft a dozen or two of thefe, for black and white are a great deal more ufed than any other colour. zd Black. Take ivory black ground very fine with com- mon water, add to it a very little ground indigo ; for a bluifli caft will enliven the black, and help that deadnefs, which a plain black alv/ays carries with it. BROWNS. ijl Brown. Take for a light brown fome fuller's earth, grind it well with water, and mix with it fome ground chalk or whtte lead, to make it in different colours, that is lighter or darker, as you think proper ; mix this up with pale ale-wort boil'd thick, and have at leaft four forts of it. zd Brown. Take fome Spanijh brown ground very well, and mix with it fome fuller's-earth, to make it lighter, for the Spanijh brown is a dark colour of itfelf j and when you have made this mixture, you may put to fome part of it a little chalk or white-lead ground in different proportions, to have them of different (hades ; Thefe are for the lighter browns, and mix them . C R A them feverally in paftes with a light fize of fi{h glue, or ifin- glafs and water, and fome of them with pale ale-wort boil'd thin, or thick water-gruel boil'd with gum-dragon ; then make them into Crayons. 3 J Brown. Take Spanjjh brown ground fine, and fome In- dian red ; mix them well together, and to them put fome pale ale-wort, till they become a pafte. You may make fome of them lighter with chalk, or white-lead ground^ then roll them into Pajiils. GREENS. \Ji Green. Take fome verdegreafe, and boil it in (harp vi- negar, and when it boils, add a little tartar powdered, which will fo difTolve the verdegreafe, that the liquor will be of a fine colour ; then fet the liquor in little gallipots expos'd to the air, which will dry the colour, and then it will diflblve in common water. This may be taken with as much warm ale-wort as will - cover it, and will diflblve the green ; then make it into PaJlils, with ground white chalk, as much as you think fit. zd Green. Take diftill'd verdegreafe ground with vinegar on a marble, wafh it well with water ; the manner of which is, to throw the verdegreafe into water, and in half a minute to pour off the water into a cup, and let it fettle ; then pour the water from it, and wafh it again in the fame way j and when this is dry, make it into Pajiils with ale-wort. i,d Green Take verdegreafe prepar'd as before, finely pow- dered, and mix it with a little Prujfian blue in feveral propor- tions. In the lighteil forts, put a little white, or the brightefl yellow well ground, to make varieties of colour i mix all thefe with pale ale-wort boil'd to a thicknefs. 4/Z» Green. Take Indigo well ground, and fome Englijh pink ; mix thefe well together upon a marble, and when they are well powdered, make them into a pafle, and roll them up with a foft fize and oil into the fhape of crayons, or with pale ale-wort or thick water-gruel; but when you ufe water-gruel, it muft be ftrain'd and boil'd with fome gum-dragon. ^th Green. Take blue bice ground fine, add to it (omt Dutch pink well ground ; mix them in parcels, and prepare them in {hades to one another ; then make them into paftes, and roll them into Pajiils. You may have five or fix forts of thefe. Notey The liquid you ufe to make them into PaJlils, muft be ale-wort boil'd a little thick. 6th Green. Take rock indigo ground very fine with water on a marble, and when 'tis dry, beat it fine again ; then divide it into parcels on the marble, and to fome of them put a little flower of brimftone in greater or lefTer quantities; to others flower of brimftone and Dutih pink mixt, fo that you may have variety C R A variety of colours. When you have thus made the different fhades you intend, then make them into partes with ale-wort thickened by boiling with white glover's fhreds of leather, or a little gum-dragon ; and roll them into Crayons. jth Green. Grind rock indigo with water, and put to it in feveral parcels, as much Dutch pink as you think fit, to make your greens of various fhades ; when thefe are weU mixr, put to them fome ale-wort thickened by boiling, with w^hich make them into paftes ; then roll them into Pa/iils. Note, The reafon why thefe Pajiils are better than thofe in common which are bought at fhops, is becaufe they are gene- rally made too ftiff with gums, and io will hardly touch the pa- per ; and all thefe will work freely, and exprefs the feveral co- lours you defire. The reafon why you are to make five or fix fhades of each colour is, becaufe we cannot mix any when we ufe them; where- as in oil-painting, and painting in water-colours, we can make what mixtures we pleafe in an inftant : And when we are about any painting or drawing in Crayons, which happens to have a great variety of colours in it, we ought to have every fort of colour that can be thought on. Note, Thefe colours fhould be kept in a box partition'd, every fort by it felf, viz. The White. Yellows. Lay the brighteft forts in one, and the deeper forts in another, till you come to the orange-colours. Orange- Colours. The lighter forts in one apartment, and the deeper in another. Reds. The paler forts, or flefh colours, in one apartment, the brighter reds in another, the flronger reds in another, and the deepcft reds in another ; every one with its proper fhades, till we come towards purple. Purples. The paler forts inclining to red in one apartment ; the next forts, more inclining to blue, in another, with their fhades; and thofe which are next to blue with their fhades, in a part by themfelves. Blues fhould follow the purples ; put the lightefl in the firfl apartment, the next degree into another, a third into another, and the fourth to the laft into others: But the Prujjtan blue keep quite by itfelf, and its mixtures by themfelves ; it ferves very well in this way to fupply the place of ultramarine, and it is much cheaper, for a Crayon made of ultramarine v/ould coft not lefs than half a guinea. And befides in this way of Crayon- d rawing, the preparation of Prujfian blue does very well anfwer the fame end, though that colour will not do in water-colours, nor even laft in oil-colours, if it comes to be expofed to the weather. C R I weather, for in either cafe it changes to a dirty yellow-colour ; but I find the Crayons hold, by being imbodied as I have di" re
