INTRODUCTION* 
 
 The study of mineral names is an interesting one, not only from the 
 mineralogist's point of view, as affording an insight into the growth aud 
 development of this branch of science, but also to the student of human 
 nature, for many traits of character are shown in the various considerations 
 which have determined the particular name to be adopted. 
 
 We sometimes find as the reason for a name the simple idea of distin- 
 guishing the thing itself; but this is not the most common reason. To do 
 honor to some person who may perhaps be pleased or flattered by the atten- 
 tion, or to immortalize some place, often otherwise obscure or unknown, is 
 a much more common reason. Names have been given to commemorate 
 battle-fields, to sneer at the work of earlier investigators, and as a tribute 
 to feminine loveliness. In short the whole round of human passions has 
 been gone over in the manufacture of these words, which are purely scien- 
 tific in their uses, and for the making of which scientific methods might 
 well have been employed. The subject has also no little Interest from the 
 pliilological side, and these names deserve study if only as part of our 
 language. 
 
 One of the most noticeable things about mineral names is the lack of 
 uniformity in their terminations. While the large majority of them end 
 in -ite, there are many in -ine, while -ane, -ase, -ose, and several others 
 have been often used. It is to be regretted that the termination -ite has 
 not been universally adopted, for it has been so far adopted as to be the 
 generally accepted one for such names. It has the sanction of antiquity, 
 for it was used by the old Greek writers in the forms ites or -itis, as in 
 ai/iaTiTTji, 'hematite,' and dXapaaTin'i, 'alabaster.' Such forms were 
 also used by the Romans, and we have in Pliny siderites, 'lodestone,' 
 steatitis, 'soapstone,' molochites, 'malachite,' and many others. These 
 forms are undoubtedly the source of the termination -ite now in use, as 
 they are the earliest known terminations. Such names were given by the 
 ancients as noting some property or use of the mineral, or sometimes desig

 of Mineralogical Names,' read before the New Yorlc Academy of Sciences on January

 nating its source, or the locality from which it was derived; as uayvfjiis, 
 a mineral from Magnesia. Or, to speak of those already mentioned, 
 aiudziTTii is a mineral resembling blood, so called from the color of its 
 powder; oiXafiaaTixii, a mineral from which a vessel called an alabastron 
 was cut; siderites, from aiSripoi, 'iron,' because it contains it; steatitis, 
 from a-rearoi, 'of fat,' because it feels greasy; and molochites, from 
 juaXax''?, ' mallows,' alluding to its green color. In the 5th edition of his 
 great work on Mineralogy, Prof. J. D. Dana makes an attempt at uniform- 
 ity of nomenclature by changing the terminations of many names into ite, 
 particularly those ending in -ine, only leaving those unchanged which had 
 come into too general use in the language to be so treated. So we have 
 galenite, alabandite, pyrrhotite, and periclasite, instead of galena, alaban- 
 dine, pyrrhotine, and periclase. These changes have been generally 
 adopted, and are all in the right direction. 
 
 In 1876 Prof. C. U. Shepard published a ' Catalogue of Minerals found 
 within about 75 miles of Amherst College, Mass.,' in which he proposed 
 that the names of all acknowledged mineral species, except those of the 
 elements and a very few more, shall uniformly end in -ite, and that the 
 termination -ine shall as uniformly be used for all variety names, and those 
 whose specific character is not fully settled. Accordingly, he gives us 
 gypsite, serpentite, wadite, orthoclasite, spodumenite, epidotite, and many 
 similar changes, while marmolite, picrolite, nacrite, and others are made 
 to end in ine, marmoline, picroline, nacrine. It is hardly necessary to say 
 that these suggestions have not been generally or fully accepted. 
 
 The use of the termination -lite, in German -lith, from the Greek ^z'floS, 
 'a stone,' ought here to be mentioned, as it was a genuine attempt to intro 
 duce a distinguishing mark for mineral names, which, if successful, would 
 have been of great benefit to mineral nomenclature, as bringing in the 
 desirable element of uniformity. This also comes from antiquity, being 
 found in the Greek. But it never came into general use, and in later years 
 is seldom used except for euphony. There is an erroneous impression 
 that the termination -ite is derived from this, which, as we have seen, is 
 not the case, as it is a much older form. 
 
 As all scientific works were written in Latin up to a very recent date, 
 and as there was no chemistry to show differences in composition, there 
 was no real progress in mineralogy. External characters alone were used 
 as means of distinguishing minerals from each other, and those that looked 
 alike must necessarily be classed together. Pliny's names were suflBcient 
 for all the uses of the science down to the sixteenth century. There was 
 hardly a name added, even by Agricola, whose large works were published 
 1529 to 1546. The name fluor is perhaps his only new one, and that he

 probably did not originate, but look from the vocabulary of the furnace- 
 men, who used fluor-spar in smelting their ores. Certain minerals in general 
 use had their common names in various languages, but there were few of 
 them. 
 
 Several attempts have been made to give systematic names to minerals 
 on some such principle as is used in other branches of natural science, but 
 not one of them has been generally adopted, and all have by degrees been 
 dropped. One of the earliest of these was by Sir John Hill, in his ' History 
 of Fossils,' London, 1748. He divides minerals into numbered series, 
 classes, and orders, and under these into named genera and species. His 
 genus names are many of them new, but are sometimes older names modi- 
 fied to suit his system. For instance, Marmora, for the marbles. A good 
 example of his new names, and also of the way in which species were 
 multiplied when only external characteristics were considered, is in the 
 order of Inflammables. The 3d class is called PhlogoniiE, and under this 
 we have as the 1st genus, Pyricubia, and under this two species: 1st, 
 Pyricubium maximum foliaceum, and 2d, Pyricubium solldum minus. 
 The first of these species is simply those cubical crystals of iron pyrites 
 which are striated by an oscillation toward a hemitetrahexahedron, and 
 the second is the unstriated crystals of the same. Octahedral pyrite is 
 made another genus, and dodecahedral is still another. Several more 
 genera are made trom what is now the one species. This system never 
 ■came into general use, and Hill himself gives it up and adopts one much 
 more simple in his later work entitled 'Fossils Arranged according to 
 their Obvious Characters,' London, 1771. 
 
 In 1820 Prof. Mohs brought out a small book entitled ' The Characters 
 of the Classes, Orders, Genera, and Species; or the Characteristic of the 
 Natural History System of Mineralogy. Intended to enable students to 
 discriminate minerals on principles similar to those of Botany and Geology.' 
 This system is more fully presented in his larger work of 1822-4, trans- 
 lated by Haidinger in 1825. He uses genus and species names for each 
 mineral, and sometimes adds a third for more exact distinction. Under 
 the genus garnet he gives Pyramidal Garnet, or idocrase; Dodecahedral 
 Garnet, or true garnet; and Prismatoidal Garnet, or staurolite. Dioptase 
 becomes Rhombohedral Emerald-Malachite. This system was quite popu- 
 lar for a time, and had several imitators. Prof. C. U. Shepard adopts 
 Mohs's system, and in the first edition of his mineralogy, 1832-5, he not 
 only uses his names, but extends the system still further. He, however, 
 gives first the common or trivial names, as they are called, and always uses 
 them in speaking of species. Microlite is the one new species of his own 
 noted in this book, which under the sj'stem he calls Octahedral Tungstic- 
 
X INTRODUCTION 
 
 Baryte, and similar names are carried all the way through. None of these 
 names are mentioned in his third edition, 1853-7. 
 
 In 1836 Prof, J. D. Dana read a paper before the New York Lyceum 
 of Natural History, entitled ' A New Mineral Nomenclature,' in which he 
 presents a complete arrangement according to the Natural History method, 
 and gives some very good reasons for its adoption. This system is carried 
 out in full in the first edition, 1837, of his Mineralogy. He uses in general 
 two names for each mineral, as Andalusius prismaticus for andalusite, but 
 he gives the common name first in all cases. In his second edition, 1844, 
 he retains these Latin names as the scientific ones, and as necessary to 'a 
 systematic idea of the science,' but adds, p. 135, 'the shorter trivial names 
 should however be retained, as more convenient for common use.' In the 
 third edition, 1850, however, Prof. Dana discards the whole system, not 
 even retaining the names as synonyms. A system of arrangement is 
 adopted that was understood to be temporary, while at the end of the work 
 a chemical classification is suggested. In the later editions this last has 
 been perfected, and we now have an arrangement easy of reference and 
 answering all purposes of classification, but from which all traces of the 
 double Latinized forms of the Natural History methods have disappeared. 
 This or some similar system is now generally followed by writers on miner- 
 alogy, much to the satisfaction of those who use their works. In 1847 
 Glocker published his work entitled ' Generum et Specierum Mineralium 
 Synopsis.' This is perhaps the most successful attempt at a systematic 
 nomenclature that has been made. He uses in general a Latinized form of 
 the common name for the name of each species, with some descriptive 
 word added. For varieties he adds a third word, as is common in other 
 branches of natural history. For instance, under Granatus, garnet, he 
 gives three species: 1st, Granatus nobilis, precious garnet; 3d, Granatus 
 hyacinthinus, cinnamon garnet; and 3d, Granatus vulgaris, common 
 garnet, and under the latter he uses for varieties the terminations fuscus, 
 niger, viridis, flavus, and albidus. The work is in Latin, thus going back 
 to the style of the scientific books of the last century. Recently Prof. T. 
 Sterry Hunt has devised a new Natural System, suggested indeed as early 
 as 1853, but as he gives few new species names a discussion of it would be 
 out of place here. His work is, however, exceedingly interesting, and will 
 well repay examination by those who care to go further into that side of 
 the general subject. 
 
 In 1728 Dr. John Woodward published a work entitled ' Fossils of all 
 Kinds Digested into a Method, Suitable to their Mutual Relations ami 
 Affinity,' but it is a description from external characters only, and can 
 hardly be called a scientific treatise. The first one that really deserves- 
 
INTBODUOTION XI 
 
 such a name is by the Swedish mineralogist Wallerius, in 1747, which is 
 arranged on a scientific plan, and gives us the earliest systematic descrip- 
 tion of minerals. Cronstedt, another Swedish chemist, ten years later gave 
 us a work of much greater value, as he brought in chemical relations, as 
 far as was possible in the crude state of that science. But few new names 
 were added, for the study was still largely from the external side, and new 
 species could not be recognized. With the discovery of oxygen in 1776, 
 and the real beginning of the science of chemistry, a more correct basis for 
 the differentiation of mineral species was found. This was aided by the 
 application of scientific crystallography, the first edition of de L'Isle's work 
 appearing in 1772, and the second, in four volumes, in 1783. From this 
 date new names were given to minerals as the result of more extended 
 research in this branch of study, and one of the first of these was prehnite, 
 given by Werner to a mineral brought from the Cape of Good Hope by 
 Colonel Prehn, and hence named after him. Werner first announced the 
 name in his lectures in 1783, as he himself states later, but it was not pub- 
 lished for several years. In 1789 there is an article in the Journal de 
 Physique, by Sage, objecting to the use of names of persons for minerals, 
 the text for which is this name of Werner's. But the name has kept its 
 place, and is now the accepted one for the species. Other names, given 
 about the same time after persons, are witherite, after Dr. Withering, who 
 first described it, and torberite, later changed to torbernite, after Torbern 
 Bergmann, its first analyst. This latter mineral has gone through various 
 vicissitudes as to its name, and a list of them, as an illustration, may not be 
 out of place here; they are taken from the 5th edition of Dana's Mineral- 
 ogy, p. 585: Mica viridis, 1773; Chalkolith, 1788; Torberite, 1793; Uran- 
 glimmer, 1800; Torbernit, 1803; Uranite, 1814; Uranphyllit, 1830; Cupro- 
 uranit, 1865. 
 
 The author's study of the history of mineral names was begun in the 
 interest of Murray's New English Dictionary, where these names are con- 
 sidered as words simply, and part of the language as found in books. The 
 information sought with reference to each is 1st, the author of the name; 
 2d, the date of its first publication; 3d, a reference to the original publica- 
 tion; 4th, its first form, if different from the one now used by English 
 writers; 5th, its derivation; 6th, the reason for the name; 7th, a short 
 description, sufficient to identify it, particularly if the name has been used 
 for more than one species or variety. A good example is Eriuite, a mime 
 given by W. Haidinger, 1838, Ann. Phil., 3d, iv, 154, from Erin, because 
 it was supposed to have been found in Ireland. It is a green, fibrous, arse- 
 Biat-e of copper. This description is necessary to distinguish it from Erinite 
 of T. Tliomson, 1836, Thorn. Min., i, 343, derived also from Erin, for the 
 
XU INTRODUCTION 
 
 same reason, and properly so, for it came from Ireland. But this is a 
 reddish, clay-like mineral from the Giant's Causeway, and probably does 
 not merit a name at all. 
 
 Full information about many naiues is easily obtained, and is usually 
 to be found in the last edition of Dana's Mineralogy, up to 1892. But with 
 reference to a considerable number of names the information wanted is not 
 easy to obtain, and in some cases perhaps it cannot be found at all. When 
 it is not given in Dana's Mineralogy, the student may be sure that he must 
 search to find it. This is particularly true of obsolete names, information 
 about which must often be sought in the earlier volumes of scientific 
 journals. The first publication of T. Taylor's name killinite is in 1818, in 
 vol. xiii, p. 4, of the Transactions of the Royal Irish Academy, a fact not 
 given in any work on mineralogy. There are some names also about 
 which very erroneous ideas as to derivation prevail, and which need cor- 
 rection. The name chabazite was given in the form chabasie, by Bose 
 d' Antic, 1780, Jour. d'Hist., ii, 181, and is derived from ;i;ar/SaC205, the 
 name given to one of the stones mentioned in the Orphic poem ' Ilepi 
 XtQor.' 'The name as we now have it in the poem Is x'^^'^'Z^oi, and the 
 mineral should therefore have been called chalazite. Kidd called attention 
 to the blunder in 1809, Kidd Min., i, 249; but the original name has held 
 its place. It is but fair to say that the form x^'P^'Zioi was used in the 
 current editions of the poem at the time the name was applied. The deri- 
 vation of the word datholite has often been incorrectly given. It is really 
 a corruption of the original name datolith, given by Esmark in 1806, from 
 SarSo/iai, to divide, alluding to the granular structure of one of its 
 varieties, and AzfloS. Werner added the h for no apparent reason, and the 
 changed form was adopted by most authors until Prof. Dana, in 1868, un- 
 riddled the matter and gave it its correct form again. But wise writers 
 have tried to find another derivation for it, and one author of note says it 
 is from SafloS, which he says means turbid, because the mineral is not 
 clear and transparent. A wiser one says there is no such Greek word as 
 ddBoi, which is true, and that it is from the compound word 8a-6oXXos, 
 meaning very turbid, because it is never found in transparent crystals, 
 which is no more a proper derivation than the other. The word feldspar 
 has been changed into felspar for no better reason than that the latter form 
 was thought the right one. It was used by Wallerius in his Mineralogy 
 of 1747, p. 65, in the Swedish form felt-spat, meaning fleldspar. It did not 
 originate with him probably, but may have been a popular name in his time. 
 Da Costa used it in 1757, Nat. Hist. Fossils, 287, in the German form feld- 
 spath, and this form was current until 1794, when we find in Kirwan's 
 Mineralogy, vol. i, p. 317, the following note: ' This name seems to oe 
 
INTRODUCTION XIU 
 
 derived from fels, a rock, it bbing commouly found in granites, and not 
 from feld, a field; and lieuce I write it thus, felspar.' This assumption of 
 Kirwau has been taken for fact by all English writers, and the corrupt 
 form is in very general use. Another interesting case is that of the name 
 pyroxene, which is popularly supposed to have been given, from nvp, 
 'fire,' and ievoi, 'a stranger,' in the idea that it is of rare occurrence 
 among volcanic rocks, while in fact Hafly expressly states, 1801, Hal'iy 
 Min., ii, 64, that it is very abundant among the volcanic matters of Vesu- 
 vius, Etna, etc., but is there as a stranger, the name expressing that it 
 is not m its native place, but existed in the non-volcanic rocks which 
 furnished the original material of the lava. 
 
 Authors often omit giving the reason for adopting a name. Where it 
 is on account of some characteristic of the mineral, its author often takes 
 it for granted that it is as evident to others as to himself. The name 
 coracite, J. L. Le Oonte, A. J. S. , 2d, iii, 117, is a case in point. Le Conte 
 does not give any derivation, but it is the name of a pitch-black variety of 
 uraninite, and is probably derived from icopa^, a raven. A similar case is 
 that of adinole, Beud. Min., 1832, ii, 126. No derivation is given, but it 
 may easily be conjectured from the description that it is from dSivoi, ' com- 
 pact.' But there are other cases where there is nothing suggestive in the 
 descripti9n, and even conjecture is at fault. Such conjectures if stated as 
 such are of value, but to give them as facts, as has often been done, is cer- 
 tainly a serious blunder, if not something worse. In one of the large dic- 
 tionaries we find the name acauticone derived as follows: from 'Greek 
 ocKri, point, ocvTi, against, and Kwvoi, cone.' This is a mere guess. The 
 name was given by B. J. d'Andrada, 1800, Jour, de Phys., ii, 240, in the 
 form akanthicone, and is derived from iXKavBii, a gold-finch, and Kovia, 
 powder, because the color of the powdered mineral is yellow. A similar 
 blunder is made with the name alvite, so called after one of its localities, 
 Alve, Norway. In the dictionary it is said to be derived from alvus, 
 the belly. Another instance of a mistaken derivation is that of coveite, an 
 obsolete synonym of agalmatolite, popularly supposed to be from Oorea, 
 probably because agalmatolite is from China, and Corea is close by. The 
 name was given by /. 0. Delametherie in 1795, and he derives it from 
 xoipeioi, ' of a swine,' because of its greasy appearance. He at first calls 
 it koireiite, but changed it to koreiite, and then to koreite, which has since 
 been changed to its present form, resembling one derived from the name 
 Corea. But the name should be choireiite, commencing with e/t. 
 
 Sometimes errors of the compositor have failed of correction, and these 
 spurious words have found their way into later books as real names. One 
 of these is glorikite, 1859, Duf. Min., iii, 326, which is an error for glinkite. 
 
XIV INTRODUCTION 
 
 Gibsonlte, in the 1847 edition ot tbe same work, iii, 761, is probably aa 
 error for gibbsite, but this is not so clear. Galadsite, galadstite, and galad- 
 tite are all printer's errors for galaktite. 
 
 A curious case of this sort is seen in the various forms of the word 
 didymlte. It was announced by C. E. SchaufhauU in 1843 from Sidv/no';, 
 a twin, because it was thought to be a second silicate containing calcium 
 carbonate as part of its composition. The form was by some blunder given 
 as didrimite, but this was soon changed by the author himself to the cor- 
 rectly derived form, didymite, the original v being properly changed to y. 
 Of this word you will find in the books four different forms, only one of 
 which deserves any place in mineralogy. 
 
 Breithaupt gave the name kupholit, from ;i;ov0oS, light, and Az'flo?, to 
 a very light variety of serpentine. He leaves out the o of the original 
 word, probably because the word koupholite had been used before, being 
 an obsolete synonym of prehnite. This was first changed to kuphoite and 
 then to cyphoite, which gives little idea of its original derivation and 
 meaning. 
 
 Many more instances might be cited, but enough has been said to show 
 how much confusion has arisen through carelessness or unwarrantable 
 assumption, and how desirable it is that it should be disentangled as far as 
 possible. 
 
 In this work the endeavor is made to give complete information, as 
 outlined above, concerning all the names that have ever been introduced 
 into the nomenclature of Mineralogy. Nearly all published works on this 
 subject have been searched to prepare a complete list of such names, and all 
 available sources of information have been consulted. Many facts have 
 been received in private communications from correspondents at home and 
 abroad, a list of whose names is appended. But a number of blanks still 
 remain, after years of research, and the author greatly desires information 
 on any of the points lacking. 
 
 A number of personal names are not given in full. The use of the 
 surname only has been common with foreign writers, and in some early 
 cases it is perhaps now impossible to complete them. One of these is that 
 of Uttinger, author of the name natrocalcite. A recent and very re- 
 markable case is that of the late Adam, of Paris, author of the ' Tab- 
 leau Mineral ogique,' Paris, 1869, and an honorary member of the Societe 
 Mineialogique de France at the time of his death in 1881. The most per- 
 sistent effort has failed to disclose his full name. In answer to a letter of 
 inquiry on the subject the venerable Prof. Des Cloizeaux, his life-long 
 friend, says: ' M. Adam est mort tr6s vieux, laissant une remarquable 
 collection de mineraux 3, 1'ficole des Mines de Paris. II a toujours occup§

 Words have not been inserted under every change of spelling, but only 
 ihose necessary to a complete understanding of each case. Some of the 
 variations between c and k, i and y, and c, s and z have been omitted. 
 Meither have forms in other languages been included where they are 
 simple translations of the English names. Chemical names are also left 
 out, except such as have the sanction of use as actual mineral names. By 
 this means the number has been kept down to the four thousand six hundred 
 and twenty-seven names here given, without omitting, unless by oversight, 
 any that should be found in a work of this character. 
 
 Following the Dictionary proper is an Index to the Authors of Mineral 
 Names, which it is believed will be found of interest, as showing just what 
 names each one has given. It has been found exceedingly useful in the 
 preparation of this work.

ABBREVIATIONS 
 
 In addition to ordinary and well-understood abbreviations the follow- 
 ing special ones are here used: 
 
 f from, referring to deriTation.

 var variety. 
 
 In the abbreviated references ordinal numbers refer to series, Roman 
 numerals to volumes, and Arabic numerals to pages unless otherwise 
 stated. Numbers or letters in parenthesis mean parts, and the numbers 
 immediately following the authors' names, which are always in italics, are 
 the dates. If the original reference has not been accessible, it is enclosed 
 in brackets, and a second reference which has been verified follows im- 
 mediately. Where the original form of the name differs from its present 
 English form, it is given in parenthesis immediately after the reference. 
 Thus: 'MOROXITE. P. C. AUldgaard, [1798, Moll Jabrb., ii, 433], 
 1803, Reuss Min., ii, (2), 349 (Moroxit),' means that the name Moroxite was 
 given by Abildgaard in 1798, and first appeared in von Moll's Jahrbucher 
 der Berg- und Huttenkunde, volume ii, page 483, according to Reuss' 
 Lehrbuch der Mineralogie, 1802, volume ii, part 2, page 349, where it is 
 spelled Moroxit.
