But when I came to compare what each of us had done, 1 found my fe If in many Things to have been ant ic if a- ted by fome or other of T hem, efpe daily by my Friend, the late great Mr. 'Kvj. And there- fore in fome T^ laces I jhorten d my "Difcourfe^ and referred to them ; and in a few others, where the Thread of my T^ifcourfe would have been interrupted, I have made ufe of their Authority, as the bejt Judges ; as of Mr. RayV, for Injiance, with Relation to the Mountains and their T'lajits, and other ^rodu^s. If then the Reader Jhould meet with any Thing mentioned before by others, itnd not accordingly acknowledged by me, I hope he will candidly think vie no 'Plagiary, becaufe I can affure him I have alonq^, (where I was aware of it,) cited my Authors with their due Traife. And it is fcarce pojffible, when Men write on the fame, or a Subje^ near akin, and the Obfervatinns are obvious, but that they miift often hit upon the (avie Thinq^ : And f equently this may happen from Terfons 7?iaking Ob fit vat ions about one, and the fame Thing, without knowing what each other hath done ; which indeed, when thejirfl Edition of my To the Reader. my Book was nearly printed off, I found to he my own Cafe, having (for wajit oflDr. HookV Micrography being at hand, it being a very fcarce Book, and many Tears Jince I read it, J given ^efcriptions of two or three Things, which 1 thought had not been tolerably well obferv'd before, but are defer ib'd well by that curious Gentleman. One is a Feather, the Mechanifm of which we in the main agree in, except in his Re- prefentation in Fig. i. Scheme ii. which is fomewhat different from what 1 have repre- fented in my Fig. i8, &c. Btit 1 can ft and by the Truth, though not the Elegance of my Figures. But as to the other ^differences, they are accidental, occafion'd by our taking the Tarts in a different View, or in a diffe- rent Tart of a Vane ; and to fay the Truth, (not flattering my f elf, or detratlingfrom the admirable Obfervations of that great Man, J I have hit upon a few Things that efcafdhim, being enabled to do fo, not only by the Help of fuch Microfcopes as he made ufe of\ but alfo by thofe made by Mr. Wilfbn, which exceed all I ever faw, whether of Engliili, Dutch, or Italian 7nake ; feveral of which Sorts I have fecn and examined. The other Thing we have both of us fi- gured and defcrib d, is. The Sting of a Bee or Wafp ; in which we differ more than in the la(t. But by a careful Rc-examination, I find, that although T>r, HookV Obferva- tions To the R F. A D F R. tions are more critical than ofiy 'were before^ yet they arc not Jo true as mine. For as to the Scabbard, (as he calls ity) I could never difcover any Beards thereon ; and I dare be confident there are none, but 'what are on the fJi'o Shears. And as to the T'oint of the Scabbard, he hath rcprefented it as tubular j or blnntifli at the Tof ; but it really termt- 7iates in a Jharp Toint^ and the two Spears and the Toy Jon come out at a Slit^ or longijh Hole, a little below the Top or Toint. And as to the Spears, he makes them to be but one, and that the Toint thereof lies always out of the Scabbard. But by a ftriti Exa- mination, they will be found to be two, as I have faid, and that they always lie within the Scabbard, except in flinging ; as I have reprefented them, in Fig. xi. Jrom the tran- fparent Sting of a IVafp. And as to the Spear being made of Joynts, and parted in- to two, as his Fig. x. Scheme i6. reprefents^ I could never upon a Review, difcover it to be fo^ but imagine, that by feeing the Beards lying upon, or behind the Spears, he might take them for Joynts, and by feeing the Toint of one Spear lie before the other, he might think the Spear was parted in ti^o. But leji the Reader Jhould think himfclf impofed upon both by 'T)r. Hook and my Self, it is necefjary to be obferv'd, that the Beards for Tenrcrhooks as 'Dr. Hook calls them) lie only on one Side of each Spear, not all round them ; and are therefore not to be fecn, uti- le Cs they are laid in a due Tofiur^ in the Micro- To the Reader. Mkrofcope, viz. Jideways, not tinder, or a- top the Sfear. The lajt Thing (which fiarce defervcs mention) is the Mcchanifm of the Hair, ^hich T)r. Hook found to be /olid, like a long Tiece of Horn, not hollow, as Malpighi found it in fome Animals. And I have found both thofe great Men to be in fome Meafure in the Right, the Hair of fome Animals, or in fome farts of the Body being very little, if at all tubular ; and in others, f articular- iy Mice, Rats and Cats, to be as I have re- frefented in my Fig. 14. ^c. And now if my Inadvertency in other Things hath no worfe EffeB than it hath had in thefe, namely, to confirm, correal, or clear others Ob fer vat ions, I hope the Reader will excufe it, if he meets with any more of the like kind. But not being confcious of any fuch Thing (although probably there may be many fuch) I am more follicitous to beg the ' Reader's Candour and Favour, with Rela- tion both to the Text and Notes : In the for- mer of which, I fear he will think I have as much under- done, as in the latter over- done the Matter : But for my Excufe, I de- Jtre it may be confided d, that the textual ^art being Sermons, to be deliver d in the 'Fuljpit, it was neccjfary to infifi but briefly ftpon many of the Works of God, and to leave cut many Things that might have been admit- ted in a more free Difcourfe. So that I wifh it To the Rfader. /.'' may not be thought I have faid too much rather than too little for Jiich an Occafion and ^lace. And indeed^ I had no J^all Trouble in expunging fomc Things^ altering tnany^ and foftening the mojl^ andy in a vjord, giving in fome Meafure the IVhole a diffe- rent ^Drefs than what 1 had at firfl drawn it uf in^ and what it now appears in. And as for the Norcs, which 7nay be thought too large, I confefs I might have Jhortcn'd them, and had Thoughts of doing it, by cafl^ ing Jbme of them into the Text, as an inge^ nious, learned Friend advis'd. But when I began to do this, I found it was in a Man- ner to new-make all, and that I jhould be ne- ceffitated to tranfcribe the greateft 'Part of the Book, which f having no AffiftantJ would have been too tedious for me, being pretty well fat igu'd with it before. I then thought it beft to pare off from fome, and to leave out others, and accordingly did fo in many Places, and would have done it in more, par- ticularly, in many of the Citations out of the Ancients, both Poets and others, as alfo in many of the anatomical Obfervations, and many of my own and others Obfervations : But then I confidefd as to the Firft, that thofe Citations do (many of them at leaf) Jhew the Senfe of Mankind about God's IVorks, and that the mojl of them may be ac- ceptable to young Gentlemen at the IJniver- Jities, for whofe Service thefe Lefiures are greatly intended. And as to the anatontical Notes, and fome others of the like. Nature, mojt 5 To the Reader. moji of them ferve either to the Confirmati- on^ or the Illiiflrationy or Explication of the Text^ if not to the learned^ yet to the un^ skilful, lefs learned Reader ; for whofe fake^ if I had added more, I believe he would for^ give me. And laftly^ as to the Obfervations of 7ny felf and fome others, where it happens that they are long^ it is commonly where a Necejfity lay upon me of fully exprejfing the Author's Senfe, or my own, or where the Thing was new, and never before Tubliflfd*, in which Cafe, it was neceffdry to be more Exprefs and Particular, than in Matters better known, or where the Author may be referred unto. In the former Editions I promifed another Part I Had relating to the Heavens, if I was thereunto encouraged. And two large Im- prefflons of this Book, having been fold offy fo as to admit of a Third before the Tear was gone about ; and hearing that it is tranflated into two, if not three Languages -, but efpe- daily being importuned by divers learned Terfons, both known and unknown, I have thought my felf fajfciently engaged to per- form that T^romife ; and have accordingly pub lijhed that Tart, So that I have now carry d my Survey through mofl Tarts of the vifible Creation^ except the Waters, which are for the moft Tart omitted; and the Vegetables, which, for want of Timc^ I was forced to treat of in 6 To the Rf,adf.r. /;/ a ferfunEiory Manner,^ And to the %• dertakiiig of the former of tbcfcy having re- ce'ivd divers SoUicitations frorn Terjons un- hioiL'U as "oi'ell as kncuL'Jiy I think my felf bound in Civility to oii'u their Favour^ and to return them my hearty thanks for the kind Opinion they have Jhe'wn of my other ^erformanccsy that they have encouraged me to undertake this other Task. And accord- ingly I have begun it, and (as far as my Affairs mill permit) have made Jome ^ro- grefs in it : But Age and Avocations gro'wing upon me, I begin to fear 1 Jhall fcarce he able to Jinijh it as I izoiild, and therefore mnfl recommend that ample and noble Subject to others, who have more leifure, and would do it better than L As to Additions, 'Thave been much follici- ted thereto by divers cmiotis and learned 'Per fins, wfiqj,^€uld have had me to infer t fome of their.

I, Atmofphere. $ whole Animal World breatheth, and livech by ; not only the Animals inhabiting the Earth {c) and Air, (t) As the Air is of abfolute NecelTity to Animal Life, fo it is neccirary that it fhould be of a due Temperament or Confi- ftcnce; not foul, by re-ifon that fuffocateth : net too r.\re and thin, becaufe that fufficeth not ; with Examples of each of wiiich, I Hiall a little entertain the Reader. In one of Mr. liazvkibee's Compreffing Engines, I clofely fliut up a Sparroiv withou*: forcing any Air in ; and in lefs than an Hour the Bird began to pint, and be concerned ; and in lefs than an Hour and half to be fick, vomit, and more out of Breach ; and in two Hours time was nearly expiring. Another I put in and comprelTed the Air, but the Engine leaking, I frequently renevved the ComprefTure ; by which means, (although the Bird panted a little after the firft Hour,) yet after fuch frequent ComprefTures, and ImmifTion of frefli Air, it was very little concerned, and taken out feemingly un- hurt after three Hours. After this 1 made two other Experiments in comprefTed Air, with the Weight of two Atmofpheres injected, the Engine hold- ing tight and well; the one with the Great litmoufe, the other wich z Sparrow. Eor near an Hour they Teemed but little con- cerned ; but after that grew fainter, and in two Hours lime fick, and in three Hours time died. Another thing I took no- tice of, was, that when the Birds were (ick and very reftlefs, I fancied they were fomewhat relieved for a fliort fpace, with the Motion of the Air, caufed by their fluttering and ftiaking their Wings, (a thing worth trying in the Diving- Bell). I fliall leave the ingenious Reader to judge what the craife was of both the Birds living longer in comprelTed, than uncomprelfed Air; whether a lels quantity of Air was not fooner fouled and rendred unfit for Refpiration, than a greater. From thefe Experiments two Things are manifefted ; one is, th.Tt Air, in fome meafure comprelTed, or rather heavy, is ne- cefTary to Animal Lire: Of which by and by. The other, that frelh Air is alio neceffary : For pent up Air, when overcharged with the Vapours emitted out of the Animal's Body, becomes unfit for Refpiration. For which Reafon, in the Diving- Bell, af- ter fome time of ffay under Water, they are forced to come up and take in frcfii Air, or by fome fuch means recruir it. But the famous Cornelius Drebell conir\\cd not only aVelTelto be rowed under Water, but alfo a Liquor to be carried in that VelTel, that would fupply the want of frefbAir. The VeflTel was made for King James \. It carried twelve Rowers, befides the Paflengers. It was tried in the River of Thames ; and one B 3 Qi 6 Survey of the Book I. of thePerfons that was in that fubmarine Navigation was then alive, and told it one, who related the Matter to our famous Founder, the Honourable, and moil Ingenious Mr. Boyl. As to the Liquor, Mr. Boyl faith, he difcovered by a Dodor of Phyfick, who married Drehell's Daughter, that it was ufed from time to time when the Air in the fubmarine Boat was clogged by the Breath of the Company, and thereby made unfit for Refpiration ; at which time, by unftopping a VefTel full of this Liquor, he could fpeedily reftore to the troubled Air fuch a proportion of vital Parts, as would make it again for a good while fit for Refpiration. The Secret of this Liquor Drebell would never dilclofe to above one Perfon, who himfelf af- fured Mr. Boyl what it was. Vid. Boyl, Exp. Phyf. Mech. of the Spring of the Atr, Exp. 41. in the Digref. This Story I hAve related from Mr. Boyl, but at the fame time much quellion whether the Virtues of the Liquor were fo efFedual as reported. And as toogrofs, fo too rare an Air is unfit for Refpiration. Not to mention the forced Rarefadions made by the Air-Pump, in the following Note ; it is found, that even the extraordinary natural Rarefadions, upon the tops of very high Hills, much afifed Refpiration. An Ecclefiaftical Perfon, whohadvifited the high Mountains of Armenia, (on which fome fancy the Ark refted) told Mr. Bo^jl^ that whilft he was on the upper part of them, he was forced to fetch his Breath oftner than he was wont. And taking notice of it when he came down, the People told him, that it was what happen'd to them when they were fo high above the Plane, and that it was a common Obfervation a- moB3them. T'he like Obfervation the fame Ecclefiallick made upon the top of a Mountain in the Ceve-anes. So a learned Tra- veller, and curious Perfon, on one of the bighell Ridges of the Pyrenees, call'd Pic de Midi, found the Air not \o fit for Re- fpiration, as the common Air, but he and his Company were fain to brerih iliortcr and oftner than in the lower Air. Vid. Phil. TranfaSl. No. 63, or Lowthorp\ Abridg. Vol. 2.. p. 2i6. Such anotbc: Relation the learned Jofeph Aco/ia gives of himfeK and h^ Company, that, when they palfed the high Mountains of Peru, which they call Periacaca, ^to which he faith, the Alp^ ihemfelves fetmedto them but as ordinary Houfesy in regard of I'i'/h Toivers, ) He and his Companions were furpri- Xed with fuch extreme Pangs of Straining and Vomiting, ( not •without cafting up of Blood too,) and with fo violent a Dijiemper, that he concludes he Jlyj-'iH undoubtedly have died; hut that this laftcd KCt above three or four Hours, before they came into a more convenient and natural Temperature oj the Air. All which he concludes proceeded from the too great Subtilty and Delicacy of the 4ir, which is not proportionable to humane Refpirati- on, which requires a more grofs and temperate Air, Vid. Boyl, uht fupra. Thus Chap. I. Atmofphere. J Air {d)^ but thofc of the Waters {e) too. Without it moft Thus it appears, that an Air too Subtile, Rare and Light, is unfit for Refpiration : But the Caufe is not the Subtilty ortoo grot Delicacy, as Mr. £<>:>/ thinks, but the too great Lightnefs iliereor, which renders it unable to be a Counterbalance, or nn Antngonift to the Heart, and all the Mulcles miniftring to Refpiration, and the Diafiole of the Heart. Oi which Ice IJouk 4. (3hap. 7. Note i. And as our Inability to live in too rare and light an Air may difcouragethofe vain Attempts of Flying and VVhimlies of paf- fing to the Moon, vc. fo our being able to bear an heavier State of the Air is an excellent Provilion for Mens Occalions in Mines, and other great Depths of the Earth ; and thole o- ther greater PrelTures made upon the Air, in the Diving-Bell^ when we defcend into great Depths of the Waters. {d) That the Inhabitantsof the Air, (Birds and Infeds,) need the Air as well as Man and other Animals, is manifelt from their fpeedy dying in too feculent, or too much rarefied Air; of which fee the preceding and following Note/. Bui yet Birds and Infedls (fome Birds at leaft) can live in a rarer Air than Man. Thus Eagles, Kites, Herons, and divers other Birds, that delight in high Flights, are not affedted with the Rarity of the Medium, as thofe Perfons were in the preceding Note. So Infeds bear the Air-Pump long, as in the following Note/. {e) Creatures inhabiting the Waters need tlie Air, as well as other Animals, yea, and frefli Air too. The Hyrirocanthari of all Sorts, the Nympha of Gnats, and many other Water- Infeds, have a lingular Faculty, and an admirable Apparatus, to raife their back Parts to the top of the Waters, and take in frclL Air. It is pretty to fee, for Inftance, the Hydrocanthari come and thruft their Tails out of the Water, and take in a Bubble of Air, at the tip of their V agin & ■and TzWs, and then nimbly carry it down with them into the Waters; and, when that is fpent, or fouled, to afcend again and recruit it. So Fillies alfo are well known to ufe Refpiration, by paffing the Water through their Mouths and Gills, But Cj will hve out of the Water, only in the Air; as is manifeft by the Expe- riment of their way of Fatting them in Holland, and which hath beenpradifed herein England, viz.. they hang them up in a Cellar, or fome cool Place, in wet Mofs in a fmall Net, with their Heads out, and feed them with white Bread foaked in Milk for many Days. This was told me by a Perfon very curious, and of great Honour and Eminence, whofc Word (if 1 had leave to name him) no Body would queftion: And it being an Inlhnce B 4 of 8 Survey of the Book I. mofl Animals live fcarce half a Minute (/) j and o- thers, that are the moll accullomed to the want of it, live not without it many Days. And of theRefpiration oF Fifliesvery fingular, and fomewhat out of the way, I have for the Reader's Diverlion taken notice of it. (/) By Experiments I made my itM in the Air Pump, in September and OSlober , 1704; I obferved that Animals whofe Hearts have tv^ro Ventricles, and no Foramen Ovale, as Birds, Dogs, Cats, Rats, Mice, crc. die in lefs than half a Minute counting from the very firll Exfudion ; efpecially in a fmall Receiver. A Mole (which I fufpefted might have born more than other Quadrupeds) died in one Minute (without Recovery) in a large Receiver; anddoubtlefs would hardly have furvived half a Mi- nute in a fmall Receiver, A Bat (although wounded) fuftain- ed the Pump two Minutes, and revived upon the re-admiffion of the Air. After that, he remamed fourMmutes and a half and revived. Laftly, After he had been five Minutes, hecon- tinued gafping for a time, and after twenty Minutes I read- mitted the Air, but the Bat never revived. As for Infeih : IVafps, Bees, Hornets, Graflioppers, zx\d Lady- Cows feemed dead in appearance in two Minutts, but revived in the open Air in two or three Hours time, notvvichftanding they had been in Vacuo twenty four Hours. The Ear-zvig, the great Staphylinus, the great black lowfy Beetle, and Ibme other Infedls would leem unconcerned at the Vacuum a good while, and lie as dead ; but revive in the Air, although fome had lain fixteen Hours in the exhaufted Re- ceiver. Snails bear the Air Pump prodigioufly, efpecially thofe in Shells ; two of which lay above tv/enty four Hours, and feem- ed not much affeded. The fame Snails I left in twenty eight Hours more after a fccond Exhauflion, and found one of them quite dead, but the other revived. Fro^% and Toads bear the Pump long, efpecially the former. A large Toad, found in the Houfe, died irrecoverably in lefs. than fix Hours. Another Toad and Frog I puc in together, and the Toad wasfeemingly dead in two Hours, but the Frog juil alive. After they had remained there eleven Hours, and feemingly dead, the Frog recovered in the open Air, only weak, but the Toad was quite dead. The fame Frog being put in again for twenty feven Hours, then quite died. The Animalcules in Pepper-Water remained in F as will appear when I come to fpcuK -if them, and is manifell from their Glory and Ver- dure in a free Air, and their becoming Pale and Sickly, and Languifhing and Dying, when by any means excluded trom it {g). Thus ufeful, thus neccll'ary, is the Air to the Life of the animated Creatures j and no lefs is it to the Motion and Conveyance of many of them. All the winged Tribes owe their Flight and Buoyan- cy (/;) to ir, as fhall be fhewn m proper place : And even the watery Inhabitants themfelres cannot afcend {£) That the Air is the principal Caufe of the Vegetation of Plants, Ecrelli proves in his excellent Book D« Mot.

But ot this more when I come to furvcy Vegetables. Some Lettice-Seed being fown upon [ome Earth m the open Air, and [ome of the fame Seed at the fame time upon other Earth in a Glajf- Receiver of the Pneumatick Engine, aftervjards exhaufted of Air : The Seed expofed to the Air was grown up an Inch and half high wiihin Eight Days ; hut that in the ex~ haufted Receiver not at all. And Air being again admitted in- to the fame emptied Receiver, to fee whether any of the Seed would then come up, it was found, that in the Space of ons Week it zvas grown up to the Height of two or three Inches.
