Critical Remai^ks on the Editions of Diego de Lnnda^s Writings. By Daniel G. Brinton^ 3LD. (Read before the American PhilosojJhical Society^ Jan. 7, 18S7.) No document bearing upon the ancient Ma3'a civilization of Yucatan surpasses in importance the work written by Diego de Landa, the second Bishop of the Diocese of Merida, who was a resident of Yucatan from 1549 until 15*19, the year of his death. The description of the country and its inhabitants which he com- posed has been preserved to us in one MS. copy, now in the library of the Royal Academy of History, at Madrid. In the winter of 1863-4, the late Abbe Brasseur (de Bourbourg) tran- scribed a portion of it, and published it with notes, and a trans- lation into French, the following summer, under the title. Rela- tion des Choses de Yucatan de Diego de Landa ^ etc. (Paris, Arthus Bertrand, 1864). As it contained the signs of the cal- endar, and what purports to be the alphabet of the Ma3'a hiero- glyphic writing, as well as much material relating to the customs of the natives, Landa's Relation at once took a leading position among Americana. The well-known peculiarities of the Abbe Brasseur, however, the freedom with which he dealt with his authorities, and the license he allowed his imagination, have always cast an atmos- phere of uncertainty about his work,* and hence it was a decided * This general distrust with reference to the particular instance of the Landa MS. has been very vigorously expressed by Dr. P.

Brinton] ■^ [Jan. 7, satisfaction to have piiblisbed at Madrid, in 1884, under the competent supervision of Don Juan de Dios de la Rada y Del- gado, a literal, faithful copy of the original text. Unfortunately^, it appears simply as an ai)pendix to the Spanish translation of M. Leon de Rosny's work on the hieratic writing of Central America, and is issued to the limited number of 200 copies, all large folio. It is therefore both dilficult to obtain and needlessly expensive. Moreover, the editor, for fear of " distracting the reader," as he tells us, pointed out only a few of the differences between the correct text and that printed by Brasseur, so that the real value of the second edition of the text is not apparent until a long and toilsome comparison has been made. The leading position which Landa's Relacion holds with refer- ence to the ancient Maya civilization has led me to examine his words with cai-e, and the notes I have made will, I believe, prove of value to those who are engaged in the study of this remarka- ble people. I shall arrange these notes in three portions, as they refer to the two texts now printed, to the Abbe Brasseur's translation with its notes, and to the hieroglyphic signs, etc., in- serted in the text. The Text. In Brasseur's edition the text is divided into numbered sec- tions, each with an appropriate heading. No such arrangement is in the original. What is more objectionable, many of the para- graphs and even sections as arranged by Brasseur are entirely arbitrary, and do not correspond at all with the paragraphing of the original. Sometimes they begin in the midst of a phrase, cutting it in two, and destroying its meaning. He omits, without a word, fully one-sixth of the whole text. In his edition, p. 346, he concludes with the words, aqui acaba la obra de Landa, "here closes the work of Landa." No such words are in the original. On the contrary, the MS. he copied from continued wiih a number of chapters, one on the reason why the Indians offered human sacrifices, others on the serpents, animals, trees, ^tc, of Yucatan. Of these Brasseur says not a syllable. In copying he occasionally, but rarely, omitted sen- tences, doubtless through haste. An instance of this occurs, p. 328, where three lines of the original are dropped immediately after the word escalera^ terminating the sentence. 1887.] 'J [Brinton. lie did not hesitate occasionally to alter the original when he could not get at its meaning conveniently'. Thus, p. 100, he prints " pero que a parte de los espaiioles," whereas the original is " pero que entre los Espaiioles," which conveys exactly' the opposite sense. Again, p. 162, lines 2, 3, he writes " otras se separavan partes de su cuerpo," where the original is " se seja- van." Oddly enough, in the note on p. 104, he claims to have altered the text from " tres fiestas " to " otras fiestas," whereas the latter alone stands in the original. The proof-reading of Brasseur's Spanish text leaves something to be desired. On the first page I have noted three errors, vaya for om, haz el for haz a, and hiervas for sierras, which last error he carries into his translation. Others, as Uamaron for Uevaron, p. 20, line 1, and alcangaron for alancearon, p. 16, line 10, are not much misleading. Of greater moment is his inaccuracy in both the spelling and translation of proper names and Maya words. I shall mention a few of these : Taiza, p. 4. This is for tah itza, " the lord or ruler of the Itzas." Ulumil Cuz y Etel Ceh, p. 6. These Ma3'a words were un- derstood and translated by Brasseur as two distinct names con- nected by the copulative conjunction y, ef, and. This is not the case. They form one term, the correct spelling of which is vluumil cutz yetel ceh, "the land of the wild turkey and deer." Ciizmil, p. 12. The "Swallow-island," ah-cuzamil pelen, ac- cording to the Diccionario Maya-Espanol del Convento de 3IotuI, MS., was also called Oycen and Oycib. In these names cen means " ornament," and cib, " wax," while the prefix oy is an interjection. Maya., p. 14. The form adopted by Brasseur, Ma~ay-ha, meaning "there is no water," is incorrect. This phrase in the Yucatecan tongue is Ma yan ha. For a more plausible deriva- tion of the word Maya., see The Maya Chronicles, p. 16 (PLila- delphia, 1880, vol. i of Brinton's Library of Aboriginal Ameri- can Literature). The names of the idols mentioned, p. 16, read in the original Ixhunie, and Ixhuniefa, not Ixbunie, etc. The prefix ix in all four names is the feminine particle. The meanings are : Brinton.] ^ [Jan. 7, Ix-chel, the Lady of the Kainbow, or "of the Cheles." Jx-chebel-yax, the Lady of the green (blue) feathers. Ix-Jnm-yei, the one chosen Lady. Ix-hun-yela^ the Lady with the one adornment. Mochcovoh, p. 18. The Covohes are referred to, p. T2, as the ntme of the tribe near Champoton. The word Covoh is applied to a poisonous spider found in Yucatan, and here probably has a totemic signification. It is still, sa^s Dr. Berendt, a common family name among the Mayas. On p. 30, the original has Cochnah instead of Cochuah ; but the latter is probably correct, being a simple compound of cocli, broad or large, :ind iiah, hread or tortilla. Hvcahaihumun has no terminal n in the original. The proper form I expect is HoccGhal-hunlxun, "cosa asentada tn el suelo cada afio," relerring to the 3^ear-stones which were annually set up. Tikoch^ p. b2, orig. Tiboch. The former is correct. It means "at (the place ofj the castor-oil plants" (it, at, xkoch or koch, the Ricinis communis). Mai, p. 42. This word means ordinarily snuff, or pulverized tobiicco. Brasseur, in his note, derives from it the name Maya, forgetting that on p. 14 he had assigned a different etj'mology. Tutulxiu, p. 46. On the derivation of this name see The Maya Chronicles, p. 109. Qilan, p. 52. The proper form is oilaan, and means something filled, realized, perfected, attested, etc. Chicaca, p. 70. Brasseur saj^s that Cogolludo calls this prov- ince Chavacha-Hda. This is inaccurate. Cogolludo's words are "Choaca, que los Indios Uaman Chuuachati " (Mist, de Yu- cathan, Lib. II, cap. viii). This is a compound of chauac, large, great, and ha, water. VamuxcheJ , p. 76. The original has Namuxchel. The correct form may be Namach CheI,lhQ distinguished Chel; or Vamac Chel, some one of the Chels, or, he who is a Chel. Cojjo, p. 148, is the Ficus ruhiginosa (Aznar, Plantas de Yucatan, p. 231). Iztahte, p. 184, stands for yitz tahte, which is the native name for turpentine. 3Iitnal, p. 200, is spelled by Beltran, A^He de la Lengua Maya, Metnal. Brasseur's derivation from Nahuatl 3Iictlan is probable. 1887.] »^ [Brintcn. Ixtab, p. 202. Compounded of the feminine prefix ir, and tah, whicli as a verb means "to tie to something," and as a noun, the gallows. Uinal-Hun-Ekeh, p. 204. In the original this reads Vinal, Hunekeh. Of these words uinal is the ordinary Maya word for month; 7ii/n is "one"; but e^e^ does not appear in any of the dictionaries. Perez Dice. 3Iai/a, gives Keh as "the seventh day." Zacab, p. 212. Brasseur explains this in a note as "une sorte de mais moulu"; but the Dlcclonarlo de Motul, gives gakab, " la cana del mais," cornstalk. The name of the deity, therefore, was "The Nine Cornstalks." On the same page, zacah is in the usual form gaca, and is pulverized roasted maize mixed with cold water. Xante, on the same page, is not the cedar, as the editor supposes, which in Maya is Kuche, but "a tree from whose roots the natives obtain a 3'ellow dye " (Dice. Motul). Kami, p. 21 6, does not appear in the dictionaries. The Abba's suggestion that it is an error for Kabul is possibly correct; or it may be for Kauai, which means one who is very choice in food and raiment {Dice. 3Iotul). Batel-okot, p. 218, means "battle dance." The similarity of the Maya batel or bateel, to battle, a battle, to the English I have elsewhere noted as an odd coincidence. Chacan-cantun, pp. 220, 222. The original has chacacantun, and also Canzienal in place of Canziemil in Brasseur's text. On p. 222 and elsewhere instead of zac-u-uayeyab, the original text gives uniformly zacuuayayab. The Translation. Bishop Landa's writings on this subject were evidentl3'' mere memoranda, jotted down to await future arrangement and re- vision. The copyist contributed to their obscurity, so that passages of his ReJacion present peculiar difficulties, some of which have led his translator wide of the mark. I shall point out some of the most notable of these. p. 4. "tiene mucha lama"; "la plage y est tres etendue"; more correctly "a beaucoup de limon." p. 16. "que por esto le llamaron Lazaro"; "queles Espag- nols appellent de Lazare"; better "et pour cela ils I'appellent Lazaro.^^ Brinton.] ^ [Jan. 7, p. 24. "seis soles" is translated " trois soleils.'' p. 32. "tres cuentas de piedra buenas"; ''trois ohjets de pierre bleu travailles." It is not easy to see where this sense was obtained. p. 74. The space left blank at the beginning of § xiii is un- necessary, and there is no need to supply a supposed omission. The sense is " The adelantado did not occupy the best position for one who had enemies," etc. ' p. 116, line 1. The words "les parecia muy mal," do not mean "bien qu'elleleur parCit mauvaise," but "ce qui les defigu- rait beaucoup." Later, on the same page, "euero de veuado por curLir seco," does not mean " cuir de betes fauves tanne a sec," but "de cuir sec de chevreuil." p. 136. " Llamanse aora los nombres de Pilar los proprios"; "Leurs noms propres aujourd'hui sont comme Pilar," etc. This is a singular mistranslation. The baptismal font in Spanish is pila, Siiid "nombres de pila" means "christened names." The meaning evidently is "they now call themselves by their baptis- mal names." p. 158. Speaking of the wooden idols which descended from father to son, Landa says they were considered the most valua- ble part of the heritage, " tenidos por lo principal de la herencia." This Brasseur translates "ils y avaient la plus grand confianee." On p. 174 there are two important errors. Line 2, "losquales llaman holcanes''^ does not mean "a I'appel des holcans,^^ but "qu'on appellait holcans^^; and " que a essos holcanes sino era en tiempo de guerra no davan soldada," means that the holcans did not receive pay except in time of war, and not at all " Quant aux holcans, ils n'amenaient point la milice hors du temps de la guerre." Equally incorrect is the translation of the description of the manner in which the natives wore their mantle, p. 186. But it will not be profitable to continue pointing out such slips. I have said sufficient to show that Brasseur's translation must be care- fully compared with the Spanish text before it is accepted. A very curious error in translation occurs on pp. 48 and 172, but this time it must be charged to the account, not of the Abbe, but of the Bishop himself. On p. 48, bottom, there is the extraordinary statement that as an article of defensive armor 1887.-I i [Brinton. the natives wore "jacos fuertes de sal y de algodon," "strong jackets (made) of siU and cotton 1" And this is repeated, p. 172, with tlie specific addition that these jacliets were "quilted doubly with salt for grinding !^^ No wonder the Abbe was non- plussed by this outrageous assertion I (See his note to p. 49.) The explanation is interesting. The word in the Maya language for salt is taab^ while that for a twisted strand or cord is tab^ the only difference being in the length of the vowel. Evidently Bishop Landa, or the person from whom he derived his infor- mation, mistook the native description of these quilted jackets. They were of cotton and twisted cords (tab), the layers of the former being quilted to the latter. The historian of Yucatan, Father CogoUudo, refers to them, stating that they were called by the Mexicans (Nahuas), ichcavipiles. This is a sound Na- huatl word, found in Molina's Vocabulario, and shows that the same defense was known and employed by the Aztecs. It was also familiar to the tribes of Maya lineage in Guatemala. The Maya Characters. A close comparison of the various Ma3^a characters printed in Brasseur's edition with those in the Madrid copy proves that in the main his tracings were accurate. The Calendar beginning on p. 240 reveals, however, a number of minor differences. All of Brasseur's characters tend more to the circular form than those in the later edition wliich are ap- proximately quadrangular. Occasionally points of detail differ considerably, as for instance, on p. 240, the signs Ix and Cib. The lines for the month signs are much fainter and sharper in Brasseur, and that of the month Minan is incomplete, lacking a bracket-shaped appendage to the left. The Katun-wheel on p. ;U2 in the Madrid edition has the in- scription in its centre. The Maya words should read u uazaJdotn Katun, " their return the Katuns," i. e., the return or revolution of the Katuns. Brasseur translates the Spanish rendering of this, " gerra de los Katunes " by " la guerre on le jeu des Ka- tuns." The word gerra means neither game nor war, but is dia- lectic for gira or giro, from girar, to turn around. In the important matter of the alphabet on p. 320, Brasseur makes only one serious error, that is, that he places the first form of the letter b (No. 4 of his list) lengthwise instead of up- Stowell.] " [Nov. 5, right. He was led into what I think was another error by the disposition of the letters in tlie MS. As the Madrid edition gives a photo-lithograph of the two pages of the original text containing the alphabet and its explanation, we are in a position to examine it satisfactorily. The figures are arranged in three parallel lines across the page, and the two figures for u, stand, the first at the end of one line, the second at the beginning of the next. From their evident connection with the sign for the sky at night, I am of opinion that they belong together as mem- bers of the same sign. Or did either member of the pictographic composite serve as indicating its phonetic value ? • The designs of buildings as given by Brasseur, pp. 328, 332, 342, are much neater and more regular than in the original, where they are simply out-lined with a pen neither steady nor skillful. The disposition of the parts is, however, the same in both. From these remarks it will be seen that Don Juan de Dtos de la Rada y Delgado has laid students of Maya culture under posi- tive obligations by this new and complete edition of Landa's most important work, and it should find a place in those public and private libraries which aim to have at all a complete list of consulting Americana. THE FACIAL NERVE IN THE DOMESTIC CAT. BY T. B. STOWELL, PH.D. (Bead before the Americaii Philosophical Society, November 5, 1S86.) Introduction. The embarrassment of tlie student of comparative anatomy will be greatly relieved, and bis progress will be proportionately facilitated, if he has access to a complete description of the structural characters of a typical form. The anatomy of the cat furnishes a desirable and practical standard for comparison — at least for the Mammalia. Special reasons for accepting and adopting this standard have been presented elsewhere. (Anatomical Teclinology, 34, p. 55.) The osteology and the myology bave already been described (34, B.C.). The neurology lias been given only in part ; the anatomy of the brain has been publisbed by Wilder in the Anatomical Technology (34), and in numerous papers by the same author before scieutiflc bodies. (For the bibliography see Auatomical Technology.) Proc. ker. Philos. Soc, Vol. niV No. 125, p. 8. Diagram of the Facial iVerue.— Slowell. 1886. y [Stowell. It lias seemed desirable that the nerves of the cat be described with the same fullness of detail that has been given to the bones and the muscles.* The Vagus (27) and the Trigeminus (A.) nerves have been described ; the present study of the Facial nerve is now offered as a contribution to comparative neurology. It has been the author's aim to present the rela- tions and the distribution of this nerve, based upon repeated dissections, so as to insure, as far as practicable, the elimination of individual variation. Preparation. The cats were injected with the "starch injection mass " recommended in the Anatomical Technology (34, p. 140) ; both arteries and veins were injected, to Axcilitate identification and to insure accuracy. Alcoholic and recent specimens were used. Most of the work has been done under a magnifying power of 15-35 diameters, with the hope that no anastomotic or terminal filaments should escape notice. ^ NERVUS FACIALIS.

Respiratory nerve of the lace, Nervus facialis, Facial nerve. Anatomical Characters. — This nerve is distributed to the muscles which give expression to the face, viz., the muscles of the palpebral, the nasal, the maxillary, the mandibular and the inter-maxillary regions ; to two of the principal muscles of the ectal ear, viz., attrahens aurem and retra- hens aurem, and to the small muscles of the cartilage (pinna) ; it gives filaments to the middle ear, directly to the stapedius muscle, indirectly to the tensor tympani and those structures innerved by the tympanic plexus (Jacobson's nerve) ; it supplies the scalp (occipito-frontal muscle) and the ectal muscle of the cheek and neck (platysma myoides); it communicates with the several divisions of the trigeminus nerve upon the face, and with ganglia of the trunk, viz., with the Gasserian ganglion by a small fascicle, with the spheno-palatine through the great petrosal root of the Vidian * For the study of Individual structure the elaborate and expensive work of Straus-Durckhetm (B.), and the more accessible reduced copies of his outline plates by Professor Henry S. Williams (C), possess excellent features. The Anatomical Technology by Wilder and Gage (34) is all that can be desired in a manual which is designed "to furnish those who intend to pursue human, veterinary or comparative anatomy, with explicit directions for dissection and for the preparation and preservation of anatomical specimens, and with a cor- rect and clear account of the principal parts of an accessible and fairly repre- sentative mammal of convenient size" (Preface, 2d ed.). Directions for dissec- tion and manipulation are so explicitin tlils manual thatitseems unnecessary to describe the methods followed in the preparation of this paper. No work known to the writer, except perhaps Mivart's (18), assumes to present in detail the nervous system of the cat; the wide discrepancy between his text and the nervous system of American cats has been mentioned elsewhere (A ; The Na- tion, June 2, 1881 ; Science and the Athenseum, June 4, 1881).

It is not given to the temporal muscles, although its terminal filaments form dense plexuses upon their ectal surfaces. Physiological Characters. — This nerve controls facial expression, the movements of the ectal ear and the auditory ossicles ; it has a direct action upon the salivary glands. (Sapolini ascribes speech to the chorda tym- pani, and thinks that the further action of the facial nerve upon the tongue is to govern its movements in deglutition). I do not know that its action upon the auditory nerve has been demonstrated. Its anatomical relations suggest a modifying influence upon the trigeminus, the glosso- pharyngeal and the vagus nerves. SPECIAL DESCRIPTION. Proximate Roots. — The union of the proximate roots of the facial nerve may be traced along the ventrimesal border of the sensory root of the tri- geminus nerve caudad of the pons. Tke dorsal root bends around the caudal root of the trigeminus, crosses its lateral and dorsal faces, and enters the cerebellum with the medipe- duncle. Tke cephalic root is ventrad of the caudal root of the trigeminus and caudad of the medipeduncle ; a portion is reflected dorsad to the cerebel- lum with the prepeduncle ; the larger portion dips into the floor of the epiccele, and may be traced cephalad to the region of the post optici. The caudal root separates from the cephalic as it passes ventrad of the root of the trigeminus ; it lies ventrad of the caudal root of the trige- minus, and passes obliquely meso-caudad to the floor of the metacoele. Ectal Origin and Entocranial Relations. — The facial nerve takes its ectal origin from the latero-cephalic border of the trapezium, meso-ceph- alad of the auditory nerve (27, Figs. 1, 2 ; 34, Fig. 116, and PI. II, Fig. 3). The distribution of the cerebellar artery is such that the ectal origin is surrounded by arterioles ; a small twig from the medicerebellar artery (D ) and a venule pass between this nerve and the auditory. Tlie ento-cranial course is laterad with the auditorj'^ nerve ; it traverses the ental meatus auditorius with that nerve, its position being dorsad. Just ectad of the arteriole which separates the facial and the auditory nerves a small ramus apparently unites these nerve trunks, or rather is an accession to tlie facial nerve. Is this the intermediary nerve of Wrisberg {portio inter duram et mollem) 1 Sapolini maintains that in man this is the origin of the chorda tympani, which he names the thirteenth cranial nerve. He traced this nerve to the geniculate ganglion, and found that the nerve of Wrisberg and the chorda tympani were one and the same nerve. (From a resume of Sapolini's monograph by Dr. Burnett, pub- 18S6.1 ' J- J- [Stowell. lished in the Medical Times, February 24, 1883, and reprinted in the Medical Record, March 31, 1883, p. 363.) Intercranial Relations. — The facial nerve traverses the serpentine flex- ions of the aqueduclus Fallopii to the foramen stylo-mastoideura. The course In the aqueduct is first laterad for 2-3 mm.; an abrupt cliange iu direction at this point forms an angle which is directly mesad of the fossa occupied by the spherical tensor tympani muscle ; peripherad of the angle the course arches first dorsad (the concavity being ventro-laterad), then laterad (the concavity being ventrad) for 5-7 mm., and lies caudad of the tensor tympani muscle. About 10 mm. peripherad of the ental meatus auditorius there is a con- siderable expansion in the aqueduct, about 2 mm. in length ; in this fossa a reddish swelling rests upon the facial nerve. This is the ganglion geuic- ulatum, or intumescentia ganglitormis.* From this point the course is laterad to the stylo-mastoid foramen. At the angle (Fig. Ang. ) a considerable twig 2 mm. in length is given off, which traverses a foramen to the ental surface of the cranium, where it divides into four ramuli, which become respectively the mesal root of the great superficial petrosal nerve, the small superficial petrosal, a ramu- lus to the sympathic plexus in the carotid rete arteriale, and a fascicle to the eminence on the caudo-lateral angle of the Gasserian ganglia. At a point caudad of the stapedius muscle a fascicle, the tympanic nerve, is sent to that muscle. (It is not clear but that this fascicle has its origin in the geniculate ganglion instead of the nerve trunk.) Caudad of the geniculate ganglion the fallopian aqueduct arches latero- caudad (the concavity being mesad). In this canal, immediately caudad of the ganglion, are two fasciculi separated by a slender arteriole. These are the chorda tympani and the united anastomotic branch to the glosso- pharyngeal and the vagus nerves with the long root of the petrosal nerve, q. V. The geniculate ganglion embraces these united nerves and the trunk of the facial. About 5-8 mm. peripherad of the ganglion, where the arch reaches its ventral angle and begins to curve cephalad (the concavity being dorsad), the anastomotic branch bends ventri-mesad, and 5 mm. peripherad it bi- furcates to join the petrosal ganglion of the glosso pharyngeal nerve and the jugular ganglion of the vagus. This is a portion of the auricular branch of the vagus. This point of separation is also the origin of the long root of the great petrosal, q. v. Chorda Tympani. — This nerve, or the nervus tympano-lingualis, has its origin and course as given above ; it continues cephalad in the canal, accompanied by a slender arteriole ; it bends dorsad to enter the tj'm- panum through the iter chordce ])osterius ; it crosses the tj'mpanum about ♦The author has not at this date completed experiments to satisfy himself .is to the relation of this body ; whether tlie relation is one rif position only or one of structure — that is, whether it is a ganglion of the facial nerve, or is peculiar to the great superficial petrosal nerve and merely rests upon the facial. 19 Stowel!.] -■— ' [Nov. 5, the middle of the malleus, somewhat mesad of the bone, and emerges through a minute foramen, the iter chordae anterius, into the glaserian canal, thence along the canal to the ecto-cranial foramen ; it lies ventrad of the otic ganglion and the dental branch of the mandibular nerve, eclad of the external carotid artery, passes between the pterygoid muscles, and joins the lingual nerve at an acute angle about 5-10 mm. peripherad of the foramen ovale. Nervus petrosus superficialis major. — The great petrosal nerve has a fourfold origin. Tiie principal root may be traced to the geniculate gan- glion with the trunk which is directed caudad from that body ;* the next in size comes direct from the petrosal ganglion of the glosso-pharyngeal nerve, and is a division of Jacobson's nerve ; the third is a brancli from the trunk of the facial, at the angle ; and the fourth is a slender filament from the tympanic plexus (Jacobson's). The united trunk lies in the glaserian canal, and emerges from its ventral hiatus, enters the caudal foramen of the Vidian canal, which is about 5 ram. cephalad, traverses the canal, and at the middle of the foramen lacerum anterius becomes the petrosal root of the Vidian nerve, whence it is related to the spheno-pala- tine ganglion. Nervus petrosus superficialis minor. — This branch from the inter- osseous portion of the facial nerve is one of the four divisions of the ramu- lus given off at the angle ; about 2 mm. peripherad of its origin it enters an enlargement (plexus?) about .5 mm. in diameter; this enlargement is ioined by the tensor tympani nerve ; the petrosal nerve traverses the glaserian canal and joins the otic ganglion at the ventral hiatus. Ecto-cranial Relations. — The ecto-cranial trunk emerges from the foramen stylo masloideum ; its course is cephalad and dorsad, and lies ectad of the post-auricular artery. (It often lies entad of a branch artery to the parotid gland.) At the foramen of exit, or just peripherad, the nerve divides into branches; its relations and distribution are given ac- cordingly. The primary rami ventrad are the digastric and the stylo- hyoid ; cephalad are the cervico-facial and the tempore- facial ; dorsad and caudad are the auricular. N. digastricus. — The digastric nerve is a small ramus from the ventral border of the facial nerve at its foramen of exit ; it lies entad of the stylo- mastoid artery, around the cephalic border of whicli it bends abruptly and takes its course ventrad ; it extends along the dorsal border of the proximal end of the digastric muscle, which it penetrates about 5-8 mm. from its origin ; its terminal filaments supply the proximal end of the muscle. (I do not find an anastomotic branch to the glosso-pharyngeal nerves, as is the case in man.) N. stylo hyoideus arises from the ventral border of the facial nerve, in common with the digastric, or remains in the truuk-sheath to be given off about 1-3 mm. peripherad ; it penetrates the stylohyoid muscle at its *This trunk becomes the anastomotic branch to the glosso-pharyngeal and the vagus uerves, the chorda tympani and the long root of the petrosal nerve. 1886.] 1^ [Stowell. proximal third, and is distributed throughout the muscle ; it often com- municates with the cervico- facial nerve about 10 mm. peripherad of its origin. As it crosses the post-auricular artery it gives two or three fila- ments to the sympalhic plexus around this blood-vessel. Cephalic Division of the Nerve-Trunk. — As the common trunk emerges cephalad from the foramen of exit, it lies dorsad of the stylo- mastoid artery (a small twig from the post-auricular), and crosses the lateral border of the post-auricular artery ; at the dorsal border of the artery the trunk divides into the cervico-facial and the temporo-facial rami. (In some in- stances this trunk seems to give origin to the stylohyoid nerve.) N. cervico-facialis. — This is the cephalic and ventral ramus of the com- mon trunk ; it is ectad of the carotid artery and the facial vein, entad ot the submaxillary gland, and upon the ectal surface of the masseler muscle. At the cephalic border of the submaxillary gland it divides into three rami, the infra-maxillary, supra-maxillary and the buccal. The first brancli of the cervico-facial trunk is given off at the origin of this nerve ; it lies ectad of the carotid arterj^ and is directed dorsad and laterad upon the ectal surface of the parotid gland ; about 12 mm. from its origin, ectad of Stenon's duct, it bifurcates, each division again branching into two or four ramuli and terminating in the dermal muscle ectad ot the gland (Platysma myoides). A few filaments may be traced to the zygo- matic muscles. This branch receives a considerable accession from the temporo-facial nerve near its origin ; some of the filaments seem to terminate in the sub- stance of the parotid gland. 5-8 mm. peripherad of the origin of the cervico-facial nerve a second fascicle is sent to the zygomatic muscles. N. infra-maxillaris. — This is the ventral division of the cervico-facial nerve ; it lies ectad of the facial artery and the facial vein ; 5 mm. periph- erad of its origin it divides into several rarnuli which anastomose freely and terminate upon the platysma. A large fascicle joins the superficial cer- vical nerve from the cervical plexus. N, supra-maxillaris. — This is the middle division of the cervicofacial nerve. (It often arises as a branch of ihe buccal nerve, given off at the; border of the orbicular muscle at the angle of the mouth ; its distribution is constant.) Its general course is toward the angle of the mouth ; it lies ectad of the facial artery and vein ; it forms a dense plexus upon the ectal surface of the ventral lip ; the ventral ramuli supply the muscle between the fora- men mentale and the mandibular symphysis (M. depressor labii), and anastomose with the mental branch of the mandibular division of the tri- geminus nerve; .its filaments are also given to the orbicular muscle (M. orbicularis oris). N. buccalis is the dorsal branch of the cervico-facial nerve ; it gives several anastomotic filaments to the infra orbital branch of the tempuro- tacial nerve ; it joins the plexus at the angle of the mouth (Plexus labi- Slowell.] 14: I^Nov. 5, alis) ; a ramuscle is inflected around the angle of the mouth and anasto- moses with the buccal branch of the mandibular division of the trigeminus ; it reaches the following muscles : the buccinator, the orbicular, the 2;ygo- matic, the risorius and the depressor anguli oris ; it continues mesad along the dorsal lip between the superior coronary artery and the vein just dorsad, and at the lateral border of the arteriale rete, just dorsad of the canine tooth, the infra-orbital and the buccal nerves anastomose and form a plexitorm swelling for 3-5 mm.; from this united nerve fibres diverge to the levator muscles and to the muscles upon the nasal cartilage. N. temporo-facialis. — This is the dorsal division of the cephalic trunk as it crosses the post-auricular artery ;" it is considerably larger than the cervical division (N. cervico-fiicialis); it lies ectad of the external carotid artery, entad of the ventral lobe of the parotid gland and the adjacent lymphatic gland, and upon the ectal surface of the masseter muscle. Entad of the parotid gland, and 10 mm. peripherad of origin, it divides into three rami — the ventral, or infra-orbital ; the middle, or malar ; and the dorsal, or temporal (the malar and the temporal often remain in a common sheath for 10-12 mm., forming the temporo-malar trunk). N. infra-orbitalis. — This, the ventral division of the temporo-facial nerve, emerges from the cephalic border of the parotid gland just dorsad of Stenon's duct ; its course is arched toward the angle of the mouth, about midway between Stenon's duct and the zygoma, and lies upon the ectal surface of the masseter muscle ; it sustains anastomotic relations with the malar nerve and the temporo-auricular division of the trigeminus nerve. At the ventral border of the zygomatic muscle it gives anasto- motic filaments to the cervico- facial nerve, as described ; it lies ectad of the zygomatic muscles and dorsad of the superior coronary artery. At the angle of the mouth it gives filaments to the dorsal part of the orbicular muscle ; in its course along the dorsal lip it supplies the levator muscles, the muscle at the base of the vibrissse and the muscles which move the nasal carj;ilage ; it joins the buccal nerve to form the plexiform enlarge- ment in the rete arteriale dorsad of the canine tooth, as already described (v. N. buccalis). N. malaris. — This is the middle and large division of the temporo-facial nerve ; the central portion is covered by the parotid gland ; entad of the gland it communicates freely with the temporo-auricular nerve. At the dorsal border of the gland it is apposed to the cephalic temporal artery, and continues along with the artery just caudad of the supra-orbital ridge (the tension of the muscle will dispose the nerve cephalad or caudad of the artery). The principal divisions of the nerve make a dense plexus upon the ectal surface caudad of the supnt-orbital ridge ; the terminal filaments are given to the occipito-frontal muscle over the frontal region where they anastomose with filaments of the supraorbital nerve. At the lateral angle of the eye, where a fascicle joins the supra-orbital, a slender nerve is given off to the zygomatic muscles. The nerve trunk may be 1886.] 1^ [Stowell. traced along the supra-orbital ridge to the mesa! angle of the eye, where it joins the iulra-trochlear nerve. N. temporalis. — The temporal branch of the tempore facial nerve lies close to the basal cartilage of the ectal ear and entad of the parotid gland. The central portion communicates with the temporo-auricular nerve and sends filaments to the attrahens muscle. At the dorsal border of the gland, and at the ventral border of the long triangular cartilage which is directed meso-cephalad from the dorsal angle of the ectal ear, and which is embedded in the occipitofrontal muscle, the nerve divides ; one portion, passing ectad of the cartilage, is distributed to the occipito-frontal muscle in the parietal region ; the other, passing entad of the cartilage and along its ventral border, joins the supra-orbital plexus already described. N. post-auricularis. — This nerve emerges from the stylo-mastoid fora- men, and takes its course dorsocaudad in a groove upon the ectal surface of the mastoid process. The central 5 mm. form a loop around the post- auricular artery, one division lying ectad and the other entad of the vessel. These may be described as the auricular and the occipital portions. The auricular portion, at the peripheral end of the loop, lies apposed to the ectal or caudal division of the artery,* and is distributed to the lateral border of the occipito-frontal muscle. A ramulus from this nerve is given to the retrahens muscle. The occipital portion lies between the two branches of the post-auricular artery and is distributed to the caudal part of the occipito-frontal muscle ; it communicates with a branch of the minor occipital nerve (N. occipitalis minor). Hamuli to the Ectal Ear. — A ramulus from the auricular nerve is directed toward the tip of the ear ; 10 mm. from its origin it gives otf 4-5 ramuli, which supply the dermal muscle of the latter half of the ectal ear (probably the platysma); the nerve follows an arteriole around the caudal and the dorsal borders of the ectal ear, and bending aroimd the cephalic margin just distad of the attrahens muscle, it supplies a muscle (helicis major?) upon the ental surface of the ear. From the ental surface of the facial nerve at the stylo-mastoid foramen a considerable fascicle is directed dorsad close to the proximal cartilage of the ectal ear and entad of the auricular muscles ; it penetrates the carti- lage and terminates in a muscle (helicis minor?) upon its ental surface mesad of a projection from the ental surface of the ear near the external meatus. A third ramulus takes its orgin at the stylo-mastoid foramen ; it is ectad of the post-auricular artery, and crosses the base of the second arteriole, which is sent dorsad from the post-auricular ; it follows a small arterial twig about 6-8 mm., when it perforates the auricular cartilage with the ^ The artery divides just periplierad of the loop. Stowell.] It) ^ [Nov, 5. arteriole, and terminates upon the thin muscle (anti-tragicus?) at the base of the ear centrad of the folds which extend from the external meatus to the marginal "pocket" of the ectal ear. SUMMARY. Anatomical. Proximate Roots. — The dorsal root proceeds from the cerebellum with the medipeduncle. The cephalic root has one ental origin in the region of the floor of the epicoele or the post-optici part of the mesocojle, and another in the cere- bellum, whence it proceeds with the prepeduncle. The caudal root originates in the caudal portion of the floor of the metaccele. Ectal Origin. — This is from the latero-cephalic border of tlie trape- zium ; it is separated by an arteriole and a venule from the auditory- nerve. The Exit is by the meatus auditorius entalis, dorsad of the auditory nerve, through the aqueductus fallopii, and emerges from the foramen stylo-mastoideum. Principal Ectocranial Divisions and their Distribution. — Nervus digastricus is distributed to the musculus digastricus ; N. stylo- hyoideus to M. stylo-hyoideus ; N. cervico-facialis to the MM. platysma, orbicularis oris ventralis, depressor labii ventral is, depressor anguli oris, risorius ; N. temporo-facialis to the MM. orbicularis oris dorsalis, buc- cinator, zygomatici, levatores labii dorsalis, orbicularis palpebral, occipito- frontalis, attrahens aurem ; N. auricularis to the MM. occipito-frontalis, retrahens aurem, helicis major, helicis minor, antitragicus. Communicating Rami. Ento-cranial. — The facial nerve receives an accession just peripherad ot the arteriole which separates it from the auditory ; this is probably the intermediary nerve of Wrisberj^ or the root of the chorda-tympani (Sapo- lini's thirteenth cranial nerve). Inter-cranial. — The facial nerve communicates with the spheno-palatine ganglion by the great superficial petrosal root of the vidian nerve ; with the otic ganglion by the small superficial petrosal nerve ; with the sympa- thetic plexus by the lateral petrosal nerve ; with the Gasserian ganglion of the trigeminus by an anastomotic filament from the ramus at the angle in the aqueduct ; with the petrosal ganglion of the glosso-pharyngeal by a large fascicle from the geniculate ganglion ; with the jugular ganglion of the vagus by the same fascicle ; with the lingual branch of the trigemi- nus by the chorda tympani ; with the stapedius muscle by the tympanic nerve ; with the tensor tympani by filaments from the small superficial petrosal nerve. Ecio-cranial. — The facial nerve communicates with the superficial cer- vical nerve by the infra-maxillary branch ; with the mental nerve (man- dibular division of the trigeminus) by the infra-maxillary ; with the 17 1886.] -•- ' [Stowell. buccal nerve (trigeminus) by the buccal branch ; with the auriculo tem- poral (tripcminus) by the infraorbital branch ; with the supraorbital nerve (trigeminus) by the malar branch ; with the supra-orbital and auriculo-tcmporal by the temporal branch ; with the great auricular nerve (spinal) by the auricular branch ; with the small occipital nerve (spinal) by the occipital branch. There seems to be no anatomical relation between the facial nerve and the masseter muscle, although the nerve ramuli make a complex network over the ectal surface of the muscle. Physiological. The facial is the motor nerve of the face ; it excites contractility in the muscles of the middle ear, the ectal car (except M. attolens aurem), the cheeks, the scalp, the lips, the nostrils, the eyelids and the neck (pla- tysma). Through the vidian nerve it modifies the movements of the muscles which are controlled by ncms whose immediate origin is the sphenopalatine ganglion. Its action upon the salivary glands through the chorda-tympani is generally accepted ; further investigation may con- firm Sapolini's theory that the choida-tympani controls speech. Its anas- tomotic relations with the branches of the trigeminus suggest that much of the motor function in structures supplied by that nerve may be referred to the facial. It is intimately related with the glosso-pharyngeal and the vagus nerves. Its relation to audition is unknown. DESCRIPTION OF THE DIAGRAM. The diagram is not drawn to a scale.

By Richard Vaux. {Read before the American Philosophical Society, January 7, 1S87.) The American Philosophical Society in recording its tributes to the memory of its deceased members is sensibly impressed by the reflection that the propriety of their election to its membership had been signally confirmed by the learning and attainments manifested in their life-work. Knowledge is advancing to the circumference which bounds the human mind. Science is laboriously engaged in finding out the reason of things. Philosophy in the library is exercising its capacities, and elsewhere testing ils ability to demonstrate them. Out of these sources our Society is filled with vital force. Those who augment and increase its value are within the compass of our commendation. The preparation of this paper is the practical exemplification of this axiom. It is dedicated to the memory of the Hon. James R. Ludlow. On the 3d of May, 1825, in the City of Albany, in the State of New York, James R. Ludlow was born. His father, the Rev. Dr. John Lud- low, was a minister of the Old Dutch Reformed Church. This venerable Society had an historical character. Its influence in the earlier days of New York was marked, and much yet remains. The Dutch settlers of that Province were earnest, sincere, sluggish, but patriotic people. The Patroons were noted men in their time. The Van Rensselaer Manor was historical. The Patroons, Van Rensselaer, even to a late period were esteemed and respected in social circles. The anti-rent excitement half a century ago, was evolved out of the re- lations between these manors and the tenants. The Rev. Dr. Ludlow w^as an educated, cultivated gentleman. He was professor of languages in the Theological Department of the New Brunswick, New Jersey, School of the Dutch Reformed Church. In the year 1834 Dr. Ludlow came to Philadelphia and was elected Provost of the University of Pennsylvania, in which post he served for nearly twenty years. When Dr. Ludlow came to this city, his son James entered the Univer- sity of Pennsylvania and graduated with distinction in July, 1843. He then became a student of law with the Hon. Wm. M. Meredith. It may not be out of place to say of Mr. Meredith that he was one of the ablest lawyers of this country. Well read in all branches of learning, with a brilliant wit, his fame was the growth of inherent ability and mar- velous culture. Without industry, he absorbed knowledge. His reading was general, his memory phenomenal. On the admission of James R. Ludlow to the bar on July 34, 1846, he entered on the practice of his profession in this city. Earnest, faithful, industrious, he began to establish a professional character that promised success. In 1850 he was appointed Assistant District Attorney of the United Vaux.] ^^ [Jan. 7, States and earned high repute for his conduct of some of the Government cases. He learned rapidly the science of the law, and mastered its prac- tical details. In 1856 he was named as a candidate for the District Attorneyship of Philadelphia. His reputation had grown, his professional standing was assured. In 1857 he was nominated for Judge of the Court of Common Pleas ot Philadelphia County, and elected, and in November, 1857, took his seat on the Bench. His term of ten years expired in 1867, and he was re- elected. By the Constitution of the State of Pennsylvania, which was amended in the year 1873, the Courts of the County of Philadelphia were reorgan- ized. By this organic law, four Courts of Common Pleas were established. Each had a President Judge and two Associates. Judge Ludlow became President Judge of Court of Common Pleas, No. 3. In 1877 Judge Ludlow was again elected without opposition. He held that position until his death. His judicial life began in 1857, and ended, by his death, in 1886. Thirty years of judicial labor was the training he received. He gained the respect and confidence of his fellow-citizens. They appreciated his honesty, impartiality, his courage and his learning. As a .ludge, his reputation was substantial. In the law and equity sides of the Court he was admittedly a safe and conservative adminis- trator of the high trust conferred on him. His conscientiousness was proverbial. He possessed and developed tlie highest courage in the im- partiality with which he adjudged the questions he was called upon to determine. It may be said he died the victim of continuous, conscientious labors. He investigated and examined, and came to his conclusions after patient study of the law involved in the decisions of those cases, the importance of which made severe demands on his time. He took nothing for granted. He believed his duty required his best efforts, and was not satisfied tiiat errors inconsiderately made might be possibly corrected in a court of review. It may be said of Judge Ludlow, that in dealing with the science of the criminal law he became an authority in this counlr}\ His tastes led him to study physiology and psychology. To facilitate his labor he attended the lectures in the medical school of the University of Pennsylvania. He therefore became well informed in medical science. In administer- ing the criminal law, his opinions were regarded as a settlement of those principles in which a knowledge of these sciences was necessarily in- volved. It became a professional fashion to plead insanity to indictments for murder. Tlie first tentative efforts to introduce this defence seem. t^-. have been so successful as to encourage its adoption. The Courts, lenning to the doubt as to the mental condition of the accused when put in issue on a trial, created a demand for medical evidence in support of this plea. 1887.1 -^J- [Vaux. It became important to the administration of justice that a rigid en- forcement of the law should be secured. To relieve one guilty of murder from the just penalty of his crime, by the interposition of a scheme to confess the act and avoid the conviction, by the assertion that the accused was insane, needed to be subjected to the test of scientific investigation. Medical experts who look up the specialty of mind diseases made of it a sort of avocation. There ought to be a significant distinction between an "expert " and a "witness." This distinction is not always made in these trials. An "expert" is almost always called as a witness, while his function as an " expert " is to give merely professional opinions. Many of these experts, •so called, were too ignorant to do more than cast suspicion on the value of anj^ medical testimony. It was not long before the intelligent of both professions became disgusted with this expert system of building up a theory of want of mental responsibility for acts committed. Judge Ludlow was one of the first of the Judges in Philadelphia to de- feat the purpose for the use of these medical experts. In the Commonwealth vs. Sayres, he laid down the principles which should govern the investigation of insanity as a plea against a conviction of murder. The Supreme Court of Pennsylvania confirmed Judge Lud- low's law in this case. His opinion in this case became recognized authority. Tlie Insane Asylum at Utica, New York, published that opinion as canon law on this subject. The case of the Commonwealth vs. Taylor, 1884, was perhaps tlie most important of all the cases which were subjected to judicial determination. To those best informed as to the character of the prisoner, there was no doubt of his entire responsibility for the crime of murder of which he was convicted and afterwards hanged. The insanity plea was fully discussed, and the Supreme Court on appeal finally settled the law on this subject in the Commonwealth, by endors- ing Judge Ludlow's opinion in Taylor's case. From that opinion we make the following extract as indicating his views and asserting the law as now settled : " I do not intend to review the law as settled by our Supreme Court in Sayres' Case, 7 Norris, 201, upon the subject of insanity. "I tried that cause, and the charge then delivered was before the appel- late tribunal. On the trial of this case I quoted from that charge freely, and added the words contained at the end of the ninth reason for a new trial of record. " My object was to draw a line of distinction between what may be called legal and medical insanity, between acts which an eccentric, angry, jeal- ous, sentimental and revengeful man may do, when medically and scien- tifically, in one sense, insane, and when by every legal test that man is a ■responsible being, and for the protection of society must be held so to be. " It is quite possible for one to commit a violent act, when by reason of Vaux.J ^^ [Jan. 7, very many causes, his brain is not in a healthy condition, is in fact dis- eased, lie knows the circumstances by which he is surrounded, is per- fectly able to attend to his own affairs, distinguishes right from wrong, and yet by reason of an unhealthy brain, is abnormally swayed by pas- sion, sentiment and emotion, and in a fit of anger, jealousy or revenge, kills another. "When an expert, in answer to the question " ' Suppose a case to arise, in which the diseased condition of the brain produces jealousy, anger, or revenge ; is that man insane?' vVnswered, Yes. I then remarked : 'That is the sort of insanity the Supreme Court declares shall make a man responsible.' "That opinion is yet entertained. If the expert had answered, 'Yes, it satisfied that this diseased or unsound state of mind existed to such a de- gree, that although he (the prisoner) could distinguish between right and wrong, yet, with reference to the act in question, his reason, conscience and judgment were so perverted as to render the commission of the act in question a duty of overwhelming necessity,' we could then under- stand the difference between an opinion based upon scientific metaphysics, under cover of which every wicked man may be declared to be insane, and a clear cut, well defined rule of law, which requires every man to be a resijonsible agent, and adopts rules to test that responsibility, which every one can understand and apply, and which will in practice rarely, if ever, consign to the gallows a really insane man. "It is hardly probable in this enlightened age tliat one whose insanity is difficult of detection, and whose case may therefore be real, as well as mysterious, will ever be unjustly punished. When courts and juries deal with cases of insanity, they can and should only be governed by plain principles, readilj'' applicable to facts as proved, and not indulge in impracticable theories, often subtle, and to the ordinary mind incompre- hensible, which lead to the acquittal of the guilty, and to the final de- struction of that security which society demands." It is fortunate for medical and legal science, that a check was imposed on the vagaries of experts on mental disease. The Closest and best informed student of mental phenomena must know that it is impossible to establish and formulate any certain rules to make a reliable diagnosis as to special mental maladies. Abnormal mental con- ditions develop themselves to the recognition of educated and experienced observation. Inherited traits, latent physical causes, morbid moral alien- ations may express themselves in forms which indicate the existence ot some irrational mental conditions. In such cases the theorist accepts a conclusion of insanity. But under which of the terms used to describe this disease it can be classified, is only to be known by the results of practical personal observation of those familiar from long experience with the various characteristics of these maladies. A theoretic opin- ion is of little value. Mental disturbance may exist, and become apparent under certain forms, to the expert, when if by long and close ob- 1887.] ^'J [Genth. servation of those familiar with mental disease the responsibility of the individual for acts cannot be doubted. When, therefore, it becomes a question of the responsibility of a person for his acts, a theory is too often misleading. Judge Ludlow, in his opinion in Taylor's case, has drawn the dis- tinction with the force of scientific truth when he says. Scientific meta- physics, as applied to mind disease, may suggest medical insanity. Whatever medical insanity may be, it is now clearly determined to be the law in Pennsylvania that insanity to be a defence in murder must be de* termined by legal principles. Responsibility for crime is now to be de- termined by legal tests. Medical insanity resting on scientific metaphysics may be accepted as authority by medical experts, but before the law, legal insanity can only be recognized. This enlightened and learned Judge, worn out by judicial labor, ended his days on the 20th day of September, 1886, in the 62d year of his age, with a high reputation, gained and earned in the thirty years of devotion to tlie conscientious discharge of his high trust. It is due to the character of James R. Ludlow, that the American Philosophical Society should eni'oll his name among those of its members who worthily obtained and richly merited by his life-work the honorable distinction of its membership.

The ores which are the subject of the following investigation were re- ceived in January, 1885, from Mr. John L.

" " " " " Clace 2». " 3. " " " de San Antonio. ■" 4. Washings received from Mr. W. Schlemm. " 5. Ore from Mina Varosa. " 6. Stream tin ore, marked "Superior de Placer. " The central body of the Sierra de Catatlan, in which the mines which have furnished these ores are siluateil, consists of quartz-porphyry, which, in some places, is traversed, in a net-like manner, by small veins of tin ores. About one mile from the Mina del Diablo doleritic rocks occur. Nos. 1 and 2. Tlio vein of the Mina del Diablo has been traced for about one mile in length, it has a thickness of from eighteen inches to two feet, is almost perpendicular, and perfectly separated from the porphyry by argillaceous selvedges. It consists of a decomposed white clayey material, containing druses of quartz with tin ores. In a pocket was found a white clay in which crystals and crj'stalline aggregations (No. 1), and also finer ore (No, 2), were intermixed. On wasliing, this pocket yielded about 54 per cent of clean ore, the crystals and crystalline aggregations were picked out from a large quantity of clay, and weighed about C50 grms, yielding nearly 50 grms in well defined shape. This occurrence is completely exhausted ; the deeper and harder por- tions of the vein contain tin ores, but not any of these peculiar crj'^stals. A qualitative examination of the crystals as well as of tl'e finer ores, although different in form, showed the composition of mimelite, mixed with more orlesscassiterite, small quantities of porphj^y, quartz, hematite, clay, etc. Many interesting specimens of cassiterite, mostly of a red variety, were picked out from the mimetite crystals and crystalline aggregations ; they all showed such an unusual appearance that it was de- sirable to obtain a larger quantity from the second-class ore. The finer portion was separated by a sieve of 16 meshes to the square inch, and 500 grms. of the sifiings treated with hydrochloric acid until all the mimetite was dissolved. The residue was treated with Thoulet's solution, which gave in the heavier portion a little over 15 grams of cassiterite with a few crystals of hematite, while the lighter consisted principally of quartz, with little feldspar, fragments of porphyry, kaoline, etc. A fuller description and analyses of the various minerals and varieties from the Mina del Diablo will be given in the sequel.

As already indicated, cassiterite occurs in Mexico principally in two varieties, the most abundant ot which has a red color, while the other is yellow. a. Red variety. — Occurs in various shades of red, from bright hyacinth red, brick-red to brownish red, to brown and brownish-black. The pow- der is from pale to brownish brick-red. The general appearance of the red cassiterite proves that the dioxide of tin was in solution from which it has been deposited upon whatever substances it came in contact with, so that numerous imitative shapes were produced. Thus, we find it as in- crustations in plate like masses which formed upon quartz or porphyry, or in reniform, mammillary, or botryoidal aggregations, frequently in per- fect stalactites, which are sometimes not over 0.5™"" in length, often hol- low, radiating from the centre, often in forms resembling sponges, roots, clubs, &c. ; sometimes granular and compact, especially larger masses, which closely resemble compact hematite, towards the exterior frequently assuming a fibrous structure which may end in distinguishable crystals. The outside of the stalactites is frequently covered with exceedingly mi- nute crystals which, however, are so small and irregular that their forni can only be determined in very few cases without a microscope. Some microscopic groups of crystals obtained from the Ore No. 2 from Mina del Diablo, most of them not over 1™™ in size, are composed of an aggregation of apparently hexagonal plates of a bright hyacinth-red color with rounded 1887.J ^* [Genth._ edges, some show flat hexagonal prisms, upon quartz or porphyry, a few also are groups of minute hematite crystals, together with those of hyacinth- red cassiterite. The most remarkable and only specimen which is large enough to distinguish its form with the naked eye came from the pseudo- morphs of mimetite composition of the Minadel Diablo. It is a little group of T™"" X 5™™ in size, composed of dark hyacinth red crystals. There may be ten or more little crystals present, but only a few are perfect enough to show the form, but even these have somewhat curved faces and are not smooth enough and are too much interrupted to allow of an accurate measurement. They are slightly barrel-shaped, apparently hexagonal prisms with hexagonal pyramid and basal plane ; the largest is 3™™ high and of about the same diameter. The specific gravity of the group was found to be = 6.49G, which is evi- dently too low, probably on account of the presence of a nucleus of quartz or porphyry around which the crystals may have formed. The question presented itself, whether the observed forms were really hexagonal, in which case the dioxide of tin would be dimorphous, or, whether they were resulting from the twinning of tetragonal forms. In order to obtain a conclusive answer, I submitted this group, and also crystalline sands from the washings, received from Mr. Schlenim, to Prof. Gerhard vom Ratli, in Bonn. I am greatly indebted to him for his aid in this matter, which was ex- ceedingly difficult to determine on account of the great minuteness of these crystals, so that only one of so much experience and perseverance as he has could attempt to solve this important question. He found nearly 135° for the angle made by the apparent basal plane and face of the hexagonal pyramid, which closely corresponds to the angle produced by the first and second tetragonal pyramids of cassiterite. For one prismatic edge he found 112^^ (must be 120° in the hexagonal system), and this angle, too, is the ordinary angle of the geniculated edge of cassiterite twins. Furthermore, he was enabled to pick out crystals from Mr. Schlemm's sands, with which approximate measurements of the angles between the basal plane and the six planes of the apparent hexagonal pyramid could be made, which gave : 134° 10', 135° 15', 135°, 134°, 135°, and 134p, in agreement with the above measurements, as closely as could be expected. He writes in his last note, under date of October 26th, 1886, referring to the small group of crystals : " You may consider the determination as quadratic beyond question, assuming an hexagonal habitus by repeated twinning." The twin combination resembles figure 163, page 159, in J. D. Dana's "Mineralogy," 1868. I am indebted to Dr. Kcenig for the accompanying drawing, illustrating my group of crystals : Besides the localities mentioned, I have received the red cassiterite from Coneto, in the State of Durango, Comanja and Paso de Sotos, in the Qenth.] 28 [March 18, State of Jalisco.

Thus all the tin and arsenic, and the greater part of the iron dis- solved in water as sulpho-salts of sodium. In two instances in Analyses III and V b, I was interrupted in my work and the fusion at a low temperature was continued for five or six hours. When the mass was treated with water it dissolved with a yellowish-red color without dark green tint, and the washings also did not indicate that any iron so- dium sulphide had gone in solution. Ths insoluble residue, however, showed the iron in the form of octahedral crystals or clusters of crystals of pale brass-yellow pyri.te. 18«7.| ^"^ [Genth. I. II. III. IV. V. VI. a b a b Sp.

As cassiterite is not acted upon by acids, it is difficult to perceive in which form this tin existed. Dissolv- ing in the presence of a neutral solution of auric chloride gave not a trace of reduced gold, therefore neither tin nor arsenic were in the form of the lower oxides. There is a sufficient amount of arsenic pentoxide present to combine with all the bases ; the lead is evidently in the form of mimetite of which the calculated percentage would be 13.58 per cent, the zinc is probably there as adamite, and the amount of zinc oxide found would give 6.96 per cent of this mineral ; noarsenateof bismuth has yet been distinguished as a mineral, but there can be no doubt that the bismuth in the San Antonio ore is present as Bi^Og, AsjOj, H2O, the salt which Salkowski has first de- scribed and analyzed (Journ. fiir Praktische Chemie, 104, p. 172), the bis- muth oxide found would give 7.94 per cent of the hydrous arsenate. The insoluble portion of the San Antonio ore contains 19.300 per cent of SnO^ and 1.844 per cent of arsenic pentoxide. The atomic ratio be- tween these would be = 16 : 1. To this I shall refer again further on. The different varieties of cassiterite show a considerable variation in their speciflc gravity which, in part, is probably owing to cavities pro- duced in the process of their formation. The arsenical varieties have all a lower specific gravity. The analyses show that the red varieties are dioxide of tin, contaminated with ferric oxide, and only exceptionally containing an appreciable quan- tity of arsenic pentoxide, while the yellow varieties contain very little ferric oxide, but a far higher percentage of arsenic pentoxide and also in- variably an admixture of zinc oxide. It is difficult to perceive how these c(mstituents in such variable quan- tities could be present in apparently perfectly pure and often highly crys- talline minerals. Excepting analysis V, in which the ferric oxide is double the amount of the average of the other analyses of the red varieties, which may be owing to the fact that the little crystals of hematite which have been observed being only slightly magnetic, were not completely separated by the magnet, they give the atomic ratio between Fefi^ : SnO.^ = 1:9 and 1 : 12. Although the ferric oxide cannot be extracted from the stannic oxide by chlorliydric acid, I cannot favor the idea of a definite compound ex- isting between these oxides, and consider them only as mechanical mix- tures. The high percentage of arsenic pentoxide, especially in the appa- rently purest and highly crystalline globular variety from Mina Varosa, and the constant presence of zinc oxide are very surprising. It suggests the idea that there might be a zi)ic salt of one of the complex inorganic acids consisting of tin dioxide with arsenic pentoxide. A calculation of the molecular ratios of these constituents gave for : : 13 0.84 : 16 : ? : 24 1.2 : 31 : 1.1 : 44 : 2.36 : 68 : 123 : 1.4 1887.] 'jl- [Genth Analysis VII— As,©^ : SnO, : ZqO " of San Antonio ore, IX— AsjOj : SnO, : ZnO VIII— " X— " IV_ - VI— " This shows no rational proportions in the constituents of the cassiterite, and there is no other conclusion than that both arsenic pentoxide, ferric oxide and zinc oxide are admixtures of the tin dioxide, which is easily ex- plained, if we bear in mind the tendency of this latter substance which at the time of its formation, precipitated and retained these oxides. c. Cassiterite, pseudomorpJious after Jiematite. — It has already been stated that little red crystals of cassiterite are sometimes found associated with those of hematite. From the sands of Mr. Schlemm a few highly inter- esting, but unfortunately very small specimens were obtained. One, about 1""" in size, consists of perhaps a dozen modified crystals of hematite, with the basal plane predominating, in which latter twin groups of pseudohexagonal red cassiterite are implanted ; the occurrence reminds one of rutil which frequently occurs in a similar manner upon the hema- tite (Eisenrose) from St. Gothard. Another specimen consists of a group of tabular crystals, radiating from a centre, the whole group 3""" in diameter, which is almost completely altered into reddish-brown brilliant cassiterite, leaving a small core of about 0.5™" in size of unaltered hematite. About ten other pieces of the same kind, although far less perfect, have been observed. d. Cassiterite, pseudomorpJious after magnetite ? — A little group of crystals from the ores of the Mina del Diablo — 5 X 3°"° in size, consists of crystals which are apparently isometric octahedrons, together with some botiyoidal aggregations. The crystals are almost black, but mostly show an uneven surface, a color between brownish-yellow and yellowish-green and a waxy lustre, owing to a subsequent coating of reniform, botryoidal cassiterite upon the crystals. A fracture of the crystals shows the dark brownish-red color and lustre of the red cassiterite. The original mineral may have been magnetite. Only three of such minute groups have been found. Of great interest in connection with these pseudomorphous forms of cas- siterite are the observations of Mr. Wm. Semmons (published in London in the December number, 1883, of the Natural History Notes), who de- scribes the coating of bismuthinite (BijSj) at the Fowey Consols Mine of Cornwall with thin layers of brownish cassiterite. In a letter dated Lon- don, August 19th, 1886, Mr. Semmons gives me fuller details about this occurrence as follows : Genth.] ^-^ [March 18, "The bismuthine (bismuthinite Dana) in this mine is found : "1. As brilliant untarnished crystals. " 2. Crystals with a slight deposit of cassiterite on them. "3. With the cassiterite coating the bismuthine in concentric layers, wood tin. "All wood tin, the bismuthine having been carried away. "You doubtless are familiar with the remarkable pseudomorphs of cas- " siterite after quartz which received for a short time the name of stannite "or silicate of tin from the late John Garby," &c., &c. I should mention also the very interesting observation of microscopic crystals of cassiterite in the black zincblende of Freiberg, Saxony, de- scribed by Dr. A. W. Stelzner, and Dr. A. Schertel (Jahrbuch fiirBergund Hiittenwescn im Kouigreich Sachsen auf das Jahr, 1886). The cassiterite in the variety "Nadelzinnerz" occurs associated with quartz crystals and sometimes implanted in the same, in minute and microscopic crystals and groups of crystals. Most of the forms are simple combinations of prisms and pyramids, and have no resemblance with the Mexican specimens. The whole occurrence indicates a simultaneous formation of the zinc- blende and cassiterite. S. Hematite. Both localities, the Mina del Diablo, and that in the Catatlan mountains from whicli the sands of Mr. Schlemm were obtained, furnished minute, sometimes very perfect, crystals of hematite, occasionally grouped in the form of "eisenrose." The crystals trom Mina del Diablo are larger, at times from 2 to 3""" in diameter and have the basal plane oR more fully developed. The crystals from the sands of Mr. Schlemm are very minute, and I am indebted to Prof G. vom Rath for the following information :* Contrary to the general rule these very minute crystals, from 0.2r> to 1"™ in size show a holohedral development with the second hexagonal prism a;P2, striated parallel to the basal edge, prominent. The second pyramid §P2 (~ in Miller's mineralogy, ~ ; oR = 137° 49') dominates the polar development of these crystals. As combinations appear a more acute second pyramid f P 2 (n in Miller, n : oR = 118° 53'). R and — ^R. oR appears from a mere point to a relatively large extension.

He has taken such an interes^t in these occurrences that he communicated the results of his in vestigations to the " Niederrlieinische Ge- sellschait fUr Natnr und Heilkunde zu Bonn," at the meeting of January ILth, 1886, which have been published by this Society.

The greater portion of the ores Nos. 1 and' 2 from the Mina del Diablo consists of crystals and crystalline aggregations of a white or yellowish- ■white mineral, rough to the toucli, somewhat earthy in appearance, with a Blight resinous lustre on a fresh fracture. These crystals have been picked out from a great mass of clay and are a great rarit}', and even the crystal- line aggregations, which occurred in somewhat larger quantities, are com- pletely exiiausted. At tlie ]\Iina de San Antonio, a few but far less per- fect crystals have been observed. a. Mimetite. — Small fragments of finely granular, frequently cavernous concretions, the surf ice of which is coated with microscopic coloiless crys- tals, have been found among the above mentioned ores Nos. 1 and 3. Simi- lar crystalline coatings are sometimes observed upon the crystals, especially when in groups, which were better protected against corroding influences, and it is most likely that the whole mass of the pseudomorphous crystals consists of an accumulation of such microscopic crystals, so small, how- ever, that a fracture would show only a compact mineral with a slightly waxy lustre. Cavities of the pseudomorphous crystals are also someiimes lined with colorless microscopic crystals. It was very difficult to ol)serve any distinct forms ; when magnified 60 diameters many hexagonal planes were seen, but only one crystal was observed which showed a short hex- agonal prism, with a seccjud hexagonal prism, a pyramid and basal plane. Several others were found of the same form without the second hexagonal prism. These crystals have a vitreous lustre and aie undoubtedly mime- tite. b. Pieudomorphs of Mimetite after Anrjlcsite? — The great bulk of the ore, however, is entirely diflerent and consists of pseudomorphs which have appirently a rhoml)ic form while their composition is that of mime- tite. Tiiey are associated with stalacliticor bolryoidal red cnssilerite often in isolated crystals with all planes fully developed, upon it, or in crys- talline groups or incrusting the same. Tlie whole occurrence shows the more recent oricin of the mimetite pseudomorphs. Isolated crystals are rare, they are often cavernous and generally ar- ranged in reticulated and skeleton like groups. On a most excellent phototype plate by Mr. Frederick Gutekunst, I have given a few of the forms magnified two diameters which show best this peculiar arrange- ment : ta, 2a, and oa are the reverse of 1, 2, and 3. Measurements of the best isolated crystals gave angles which suggested the idea that the original mineral was anglesite. I have submitted these crystals and aggregations to Prof G. vom Rath, who had the kindness to make the following measurements, which, together with his conclusions, he communicated, 1. c. On account of roughness and imperfection of the surfaces of the crystals only api')rox- imate measurements were possible, which were made with the help of attached glass plates. PROC. AMER. PHILOS.

Fig. 9. Prof, vom Rath is opposed to this view ; he would look upon it favor- ably if only isolated crystals had been observed, but would consider it very strange to find the skeleton-like formation and the reticulated ar- rangement of the aggregations in anglesite. He suggests that the primitive mineral might have been reticulated galenite, and he has been supported in this view by the late Prof. Websky, Prof. Descloizeaux and Dr. Hintze. Considering galenite as the primitive mineral, the apparently rhombic forms of these pseudomorphs would be distortions or irregular hemihe- dries of isometric forms, as it is well known how frequently galenite oc- curs in forms which have not the habitus of isometric crystals. However, he was not able to reduce these oblongoctachedrons to nor- mal planes of galenite, and notwithstanding the important opinions sus- taining his views, Prof, vom Rath does not feel satisfied and expresses his manifest doubts by suggesting that, these forms might be pseudomorphs after a yet unknown rhombic mineral, having a tendency to occur in skeleton-like aggregations. I have examined the reticulated galenite specimens in Mr. Clarence S. Bement's magnificent cabinet, but could not satisfy myself that the pseu- domorphs under consideration could have resulted from such forms of galenite. Reticulated galenite is of a rather rare occurrence, and such forms would not be known, if the few localities where it has been found would not furnish it. That anglesite has not been observed in such forms before, does not prove the non-existence of the same. A suite of these pseudomorphous forms was sent by me to the Imperial 1887.] 35 [Genth. Mineral Cabinet in Vienna, and at my request, to give me his opinion. Dr. Aristides Brezina wrote me under date, Vienna, July 31, 1886 : " The pseudomorphs are evidently after mendipite* and permit to de- termine the heretofore incomplete elements of this mineral with a fair ap- proximation : m : m' =: 77° 19', mean of four measurements with the hand goniometer — mendipit measured 77° 24'. d : d' ^ 102° 23', mean of four measurements with the hand goniometer — from which it follows that the elements are rhombic, a :b:c =0.8002:1 : 0.9948 (i =0.8044) ifm = (110); d = (101). " At the same time the pseudotetragonal character is peculiar ; the difference of the parameters b and c lies within the errors of observation, but the habitus of the crystals speaks for the rhombic system." I thought it best to give these different views, trusting Fig. 10. that the future may furnish, by the discovery of the unaltered mineral, together with the pseudomorphs, the true explanation of this doubtful subject. The analysis of these pseudomorphs shows them to be mimetite in which a small quantity of the lead is substituted by calcium.

F. A. GENTH. University of Pennsylvania, April 20, 1887. Genth.] «^" [March 18, II. Vanadinite and Descloizite, a. Mr. Cliarles R. Fletcher, of Boston, formerly Superintendent of the Mammoth Gold mine, ne.ar Oracle, Pinal county, Arizona, sent me .about two years iigo a liiirlily interesting and fine variety of vanadinite and des- cloizite and sulipociuently, from a new occurrence, he presented me with a number of magnificent specimens of tlie same minerals, which, as for vanadiniic. are some of the finest which I have seen, for all of which I am greatly indebted to him. Of the first lot received I sent a small piece to Prof. G. Tom Il'Uli, who describes it [1. c.) as being composed of barrel shaped crystals with a brown nucleus, surrounded by a yellow coating of very fine aggregations of more recent growth, the druses and surfaces covered with exceedingly minute crystals of descloizite. The vanadinite from Ibis mine occurs upon quartz in crystals, varying in size from 0.1"™ to 8™™ in length, the smallest crj'slals are of a yellow color, whi« h changes with their size incntasing to an orange yellow, orange red, aurora red to a brownish-red, often variegated. Perfect isolated crystals are rare and generally small, they are mostly united to clusters and crys- talline coalings upon the quartz; the crystals are often very much dis- torted and eav(;rnous. The forms which I have been able to distinguish are the hexagonal prism with pyramid and basal plane, the latter fre- quently very .«-mall or entirely wanting. Calcite sometiines surrounds the vanadinite and is again covered by vanadinite crystals. b. A brownish-black and black descloizite from this locality covers in form of H cryst.alline coaling in minute rhombic pyramids the rcddish-white massive gold quartz, or is united to clusters of microscopic crystals upon and between the crystallized quartz. Upon these coatings of descloizite are the crystals of vanadinite, whicii again are covered with exceedingly minute crystals of descloizite. The yellow crystalline coating upon the brown nucleus, mentioned by vom Raih has often 7io nucleus of vanadin- ite, it is dull and of a yellow color Ihronghout the mass of the hexago- nal barrel sliaped crystals. Mr. fl. F. Keller, who analyzed the brown and tiie bri-lit orange red crystals from this locality (a, 1 and 2) found that the yellow mineral contains no chlorine. It is very probable therefore that the dull yellow crystals are pseudomorphs of descloizite after vana- dinite. Not enough of the descloizite could be obtained for analysis, qualitative tests however gave lead, zinc and traces of copper and manganese oxides with vanadium penloxide. c. A ]ieciiliar variety of vanadinite, much resembling pyromorphife, has been noticed in Yavapai county, Arizona, by Mr. J. C. Cooper, of To- peka, Kansas, who has sent specimens to the East. Mr. Clarence S. Bement kindly prcsenled to me one, of which I have made the analysis 1887.] *'• ,[aenth. given below (c). The crystals occur as a coating upon porous quartz, are barrel shaped prisms with basal i)1ane, from very minute to not over 4°™ in size. Their coh)r is from pale green to brownish olive green, small fragments are pale grayish green. d. Mr. J. C. Cooper presented to me a small fragment of another variety from tlie same couniy. The crystals, not over 1"°^ in size, are of brownish- red color, short liexagonal prisms with basal plane, on some a pyramid i3 slightly indicated. They cover a dark brown quartz. In some places is a very minute crystalline black coating upon the quartz, which may be descloizile. e. A ver}' interesting variety of a vanadate, which appears to be vanadi- nite, has been observed by Mr. J. C. Cooper, at tlie McGregor mine. Grant counlj'. New Mexico. The specimen, for which I am ind^bled to liim, con- sists of an impure, friable, earthy hematite, which is coated with crystal- lized calcito, frequently enveloping stalactites of the vanadium mineral, which is again covered by finely crystalline calcite. After removing the calcite by dilute acetic acid, the orange-yellow and orange-red stalactites remain. Tliey are from 3 to 5""" in length, and up to about 1°^ thick. When magniried GO diameters, they show a core of some other mineral surrounded by scaly crystals of the vanadium mineral, the f )rm of which could not be made out. A qualitative analysis showed lead oxide, vana- dium pentoxide, and chlorine as the principal constituents, hence the con- clusion that it may be vanadiuile. f. Prof. Albert H. Chester, of Hamilton College, N. Y., presented to me a few fragments of a j'ellow ferruginous quartz with a pale brownish crystalline coating, which appears to be descloizite, and upon it vanadinite in very niinute crystals mixed with larger ones from 5 to G™" in length, and 0.5 to 1.5""" in thickness, from Bald Mountain mine, Beaverhead Co., Montana. These crystals are hexagonal prisms with basal plane, some slightly barrel shaped, the greater portion of the crystals is of a dark greenish brownish color, their ends capped with almost transparent ter- minations. g. In his Re-examinatlon of American minerals. Am. Journ. Sc. [2], xx, 246, J. Lawrence Smith gives a description of vanadate of lead (descloi- zite?) from the Wheatley mines near Phoenixville, Pa., and an analysis of the same. He had only very imjiure material, mixed with a large percent- age of wulfenite, etc., for examination, so that with the imperfect knowl- edge which we then (1855) had of descloizite, he expressed his doubt whether it was this species. I have examined a specimen which came from the late Mr. Charles M. Wiieatley, at Phoenixville, and have no doubt of the correctness of Dr. Smith's determination.

Variety of Desdoizile, Cvprodescloizite, Ramirite, Tritochorite. — In 1883, Samuel L. Penfield (Am. Journ. Sc. [3] xxvi, 361) published the description and analyses of a mineral from Mexico as a variety of des- cloizite ; at about the same time, C. Rammelsberg (Berl. Acad., Berl., 1883, 1215), under the name cuprodescloizite gave his analysis and description of the same mineral from San Luis Potosi in Mexico. In a pamphlet, "La Ramirita, niteva especie mineral, Mexico, 1885," D. Miguel Velasquez de Leon gave the same mineral the name ramirite, with an engraving show- ing its appearance and an analysis of the same. In his paper Mr. Penfield referred to the great similarity of the ap- pearance and the results of the analyses of his mineral with those of Fren- zel's tritochorite. About two years ago Prof F. W. Clarke presented to me a specimen of ramirite from San Luis Potosi, Mexico, and a year ago I had an opportunity to purchase, from Dr. A. E. Foote, a number of pieces which gave such an abundance of very pure material that I thought a re-examiuation desirable on account of great discrepancies in the amounts of water and the pentoxides of arsenic and vanadium as well as cupric oxide. The mineral occurs as an incrustation from 1 or 2 to 10™" in thick- ness, radiating fibrous to fine columnar. The form of the individual crystals cannot be distinguished, they are united into groups resembling the arrangement of cockscomb barite or prehnite. The color is dark yel- lowish-brown, and the surface has a dark color, and a velvety appear- ance ; the fracture has a resinous lustre. Powder pale yellow. The spec^ grav. = 6.203. 1887.] ^" [Gentb.

In Rammelsberg's analysis the greater portion of arsenic pentoxide has evidently been weighed with the vanadium pentoxide. In De Leon's analysis the determination of water is omitted, while otherwise the results agree with ours although the copper oxide is about two per cent higher. The physical characters of the mineral and some of the determinations of the trichorite agree so closely to cuprodescloizite that it would be de- sirable if Dr. Frenzel would repeat his analysis. III. Pybite pseudomorphous after Pyrrhotite. In a highly interesting and important paper on "Natural solutions of gold, cinnabar and associated sulphides, by Geo. F. Becker" (Am. Jour. Sciences [3] xxxiii, p. 199 ff), the author shows the solubility of gold, cin- nabar, pyrite and other sulphides in alkaline solutions containing sulp- hydrates, and suggests that these minerals, found at Steamboat Springs and Sulphur Bank and similar occurrences, have been deposited from such solutions. Genth.] 40 [March 18, Several months before this paper appeared, Mr. JoRn F. Blandj'sent me from the mines near Sulphur creek, Colusa county, California, a number of specimens, containing gold in minute arborescent crystals, and crystal- line coatings upon quartz and chalcedony in a dark graj^ shale from the mines at (h:it locality, also cinnabar and pyrite, which evidently have been deposited under similar circumsiances as those mentioned by Mr [Jecker. The jiyrite is remarkable. It occurs in the same dark shah; as the gold and appears in tabular hexagonal crystals, rarely reaching 1™™ in diame- ter. A few isolated crystals arc very perfect, mostly however they are grouped together or one upon the other. Their color is pale brass yellow, they show very little lustre upon the basal plane, which is rather rough, but bright metallic lustre upon the prismatic planes. A qualitative analysis showed them lobe pyrite in composition, the form is that of pyrrhotite, they arc therefore pyrite, pseudomorphous after pyr- rholile. IV. Hessite. An interesting variety of hessite has been found at the West Side mine. Tombstone, Cochise county, Arizona, and I am indebted to Mr. Samuel W. Cheyney for specimens for the same. It is found in vein-like strings or patches in quartz, associated with cerargyrite in small crystals and crystalline coalings, a bluish green and a siskingreen mineral in too small a quantity for investigation, and minute grains of native gold. Color dark iron black ; spec. gr. = 8.359. Soluble in nitric acid without separation of gold. In analysis 1, O.Gl p. c ; and in analysis 2, 3.98 p. c. of quartz were de- ducted, and gave : 1 2 Ag = 62.87 — 62.34 Pb = 0 28 — 0 30 Fe = 37.34 — 37.05 Se = trace — trace 100.49 — 99.69 It is remarkable that no gold is combined with the tellurium, although metallic gold is associated m ith this hessite. V. Tapalpite. Prof. Carlos F. de Landero has given an account of the occurrence, the properties and the composition of tapalpite from the Sierra de Tapalpa (Boletin de la " Sociedad de Ingenieros" de Jalisco, Tom. v. Num. 3). From an analysis of it which Prof. C. Kammelsberg had made he came to the conclusion that the composition of this mineral is represented by the formula : Agj S. Big Te2. This being exceedingly improbable, and a reexamination very desira- ble, Prof. C. F. de Landero has placed me under great obligations for spe- 1887.1 "^l [Qenth. cimens of this rare species, which have furnished the material for the fol- lowing investigation : It occurs at the San Antonio mine in the mineral district of San Rafael, Sierra de Tapalpa, Sayula Canton, Stale of Jalisco, Mexico. It has a finely granular structure and a pale steel-gray color, inclining to lead-gray. Lustre dull metallic; soft. Associated with pyrite, galenile, quartz and a silicate of aluminum and calcium, and so much intermixed with them that it was impossible to ob- tain pure material for analysis. The puiest that could be selected was free from pyrile, but contained about 7 to 8 per cent of galenile and the same quantity of quartz and silicate. The specific gravity, which was found to be = 6 739, was approximately calculated for the pure mineral, and gave — 7.744. Portions from two pieces, A and B, apparently equally pure, were analyzed. A by dissolving in nitric acid; B by fusion with sodium carbonate and sulphur — the sulphur in B was determined by fusion with sodiuni carbonate and nitrate, lixivialion with water and five times re- peated evaporation with hydrochloric acid in order to reduce the telluri- to tel!urous#acid and precipitation of the sulphuric acid by barium chloride. The tellurium was always weighed as tellurous oxide. = 3 = 1 = 1.15 = 1.85 = Ag, Bi (STe)3 or 3 Ag, (STe).

Rammelsberg gives no lead in his analysis, and may have had purer material at his disposal ; it is to be hoped that such may be obtained for a subsequent investigation. VI. Allanite. A variety of allanite, closely resembling that from E^st Bradford, Ches- ter county, Pa., and lilce the latter easily decomposed into a brown earthy powder, has been sent to me by Mr. J. A. D. Stephenson, who discovered it several years ago near Statesville, N. C. The pure has a brownish-black color and a pitchy lustre. Associated with it are small zircons. Mr. Harry P.

Cooper, of Topeka, Kansas, at the Merritt mine, Socorro county, New Mexico. It occurs in very small hexagonal prisms, the largest not over 0.5""™ la size, associated with barite, quartz, mimetite, wulfenite, cerussite and a blue coating of a cupreous mineral. The willemite crystals are sometimes isolated, colorless, or black with a colorless top, mostly in coatings or ridges of aggregations of crystals filling cavities in the barite and quartz. They show only the prismatic and basal planes, the prismatic sometimes slightly striated longitudinally. In druses of quartz the microscopic willemite crystals are united to clusters, the individual crystals barrel- shaped, with deep longitudinal striation terminating in a serrated basal plane or in a point. The mimetite, which is associated with the willemite, is of a bright honey yellow color, crystallized in slender hexagonal prisms with pyramid, often without the basal plane, also united to clusters, which, on breaking, pre- sent a radiating structure. The wulfenite has a reddish-orange color, the crystals are tabular, and show pyramids of the first and second order. It was difficult to obtain a sufficient amount of the willemite, and only by selecting a larger quantity of the purest material, and partial crushing and washing oflf the lighter particles and purifying the heavier by pick- ing, I succeeded in getting enough to leave no doubt about the accuracy of the mineralogical determination. The analyses gave : 1 2 Spec. grav. = 4.098 — Barite = 0.69 — 0.69 SiO^ = 29.16 — 28.72 PbO = 2.04 — 1.98 CuO = 0.50 — 0.48 Fe^Oj = 0.10 — 0.04 Zno = 66.79 — 66.59 Ignition = 1.18 — 1.18 100.46 99.68 Analysis 1 gave 91.53, and analysis 2, 91.18 per cent willemite. Lead and copper are probably present as carbonates. 44. Cope.] ^^ [March 18, VIII. nrSINGEKITE, PSEUDOMOUPHOUS AFTEU CalCITE. Many years ago the late Julius E. Ralit, of Cleveland, Tennessee, sent me a suite of minerals from the Ducktowa mines, which he was then working. Among them was a specimen composed principally of the ores of that mine,' pyrrhotite and chalcopyrite with a small admixture of zoislte, which was covered witJi crystals of calcite, in part allcred into a dark brown mineral with resinous lustre. The calcite is in the form ot irregular hexagonal prisms, showing planes of a scalenohedron, the smaller ones terminating in acute scalenohcdrous. The largest crys- tals are abor.t 20""" in length and 10°"" thick. They all contain a nucleus of unaltered calcite, the hi>ingerite surrounding the core of cal- cite is from 2 to 4™"' in thickness. With a small quantity (0 2236 grm.) of fairly pure m itcrial I made an analysis, the results of which show that the pseudomorphous mineral belongs probably to hisingerite, gillingite or thraulite, if they are not all moie or less pure varieties of the same spe- cies.

This form differs from the typical form described by Peters, in having longitudinal color bands. These are dark-brown, and are located on the fourth, sixth and median rows of scales respectively, occupying only the middle of each row. The space between the sixth rows of opposite sides is pale brown ; external to the sixth row and below, dirty white. The en- tire coloration is so like that of the young of Apostolepis erythronotus line- atus, as to be a case of mimetic analogy. The present specimen confirms the correctness of the locality given by Peters. 38. Tantilla pallida, sp. nov.

The type is Dirrhox patagoniensis Girard, which is described in the report of the U. S. Explor- ing Expedition under Commodore Wilkes (1858, p. 139). It is a terres- trial form of Philodryas with two loreal plates one above the other. The name was first proposed in my catalogue of the Batrachia and Reptilia of Central America and Mexico, Bulletin U. S. Nat. Museum, No. 32, 1887, Index. At the same time (1. c.) I propose the generic name Atomophis for the Philodryas trilineatus of Burmeister (Dryophylax bur meisteri Jan.), in which the loreal plate is wanting. The Dirrhox lativittatus is a handsome species of moderately slender proportions, and with the head little distinct from the body. The scales are in nineteen longitudinal series, and each has a single apical pit. Muz- zle rather narrow, rounded and not truncate, the apex of the rostral plate appearing on a view from above. The internasals are as wide as long, and the prefrontals a little longer than wide. The frontal has concave lateral borders, and is about as wide as the superciliaries, and as long as the occipitals. The nasals are subequal, and the loreals are placed the one directly above the other. The inferior is parallelogrammic and horizontal, while the superior is shorter and a little higher behind than before. The oculars are 1-2. The preocular is much wider above than below, and reaches the frontal. The superior postocular is larger than the inferior. The temporals are 1-2-3. The superior labials are eight in number, the fourth and fifth forming the inferior boundary of the orbit. Inferior labials eleven, the sixth largest, and in contact with the postgeneials, which latter are a little longer than the pregeneials. Gastrosteges 184 ; anal divided ; urosteges 82. The ground color above is a pale brown, which changes to oliva- ceous on the head. A narrow black line passes from the eye along the superior edges of the posterior labial plates, and immediately behind them widens out into a brown band, which soon occupies three and two half rows of scales, beginning with the first row. This extends to the vent where it covers two and two half rows, and still narrower to the end of the tail. A brown dorsal band commences in irregular spot- tings, a lenglh of the head behind Ihe same, and soon becomes solid. 18S7.] ^•^ [Cope. covering three aad two half scales to opposite the vent. It then contracts and continues to the end of the tall.

Some small black spots on the fourth, fifth and sixth superior labial scuta. Total length, M., .668; length of tail, .153; of mouth to canthus, .016. This very pretty species resembles the Atomophis trilineatus Burm., and the Pkilodryas iceniaius Peters. Besides the peculiarity in the double loreal plates, it differs from the former in the rounded muzzle. It la obliquely truncate in the species of Burn\eister. According to Jan's figure the latter has the seventh superior labial a little longer than high, while in the D. lativittatus it is higher than long. The inferior lateral yellow stripe in the A. trilineatus is not black-bordered below. In the Pkilodryas tmniatiis the preocular plate is scarcely visible from above ; there are only seven superior labials, and the scales are said to be without pits. 56.

CONCLUSIONS. The collection made by Mr. Smith is productive of a good many inter- esting results, especially to the knowledge of geographical distribution. Such are the great extension of the range of the anurous genus Prosthe- rapis among Batrachia ; of Anolis and Scartiscus among lizards ; and of Rhynchonyx and Dirrhox among snakes. The rediscovery of a few spe- cies brought from the same region a half century ago by the Austrian, Johann Natterer, is of considerable interest. Such are the species Palu- dicola nattereri and Philodryas nattereri Steind. Other rare species only Cope.] oU [March 18, seen in this collection for the second time, are the Rhynchonyx ambiniger Peters, Rhadinma occipitalis Jan., Leptognathus turgida Cope, and Scartis- cus caducus Cope.

The Area north from Walker mountain, Bland and Giles counties. IV. The Area south from Walker mountain, Wythe, Pulaski and Mont- gomery counties. INTRODUCTION. • The reg'ioa described in this memoir, embracing Bland, Giles, Wythe and portions of Pulaski and Montgomery counties of Virginia, is the east- ward continuation of the region described in the writer's previous mem- oirs* on the geology of Southwestern Virginia. The examination of the area under consideration was purely a recon- naissance, and the notes in several localities must be regarded as little more than suggestions to the one who may make the detailed study on behalf of the United States Geological Survey. The whole area is rugged. Even the Great valley, so wide in Washington and much of Smyth county, becomes broken in Wythe by the introduction of Potsdam ridges south from the railroad, while a new fault originating in Wythe county reproduces Big and Little Walker mountains in Cove and Max Meadows mountains north from the railroad. These break the val- ley in Pulaski county also, while the fiiults of Price mountain hold be- tween them a Carboniferous area, which divides the valley in Montgom- ery county from New river almost to 'the line of Roanoke county. The whole region from the Tennessee line north-eastward to beyond the New river, as far as the writer has gone, is broken by successive pairs of Silu- rian and Devonian mountains separated by valleys of Lower Silurian limestone. The Walker mountains. Big and Little, originating in Smyth county, are continuous to beyond the eastern border of Montgomery county. The latter ridge changes its name twice, becoming Cloyd's mountain as it ap- proaches New river and Brush mountain beyond that stream ; while the former retains its name to the river and thence becomes Gap mountain. Big Walker maintains its rugged features throughout and shows but two water-gaps, those made by Walker's creek and New river, which are sep- arated by barely seven miles. Some wind-gaps exist, one of which, near * These were read before this Society and are to be found in the Proceedings, Vol. xix, pp. 88 to 107, 219 to 262, 498 to 506 ; and Vol. xxii, pp. 114 to 161. Stevenson.] ^^ [March 18, the west line of Wythe county, is thought to be available for a railroad liae. Water-gaps through Little Walker are numerous, but with one ex- ception they have been made by streams rising in the valley between the mountains or on the southerly slope of Big Walker. New river alone has made a continuous gap through both ridges. The ruggedness of Big Walker is due partly to the refractory nature of the Medina which forms its body, but more to the steep dip, which makes the mountain narrow and limits the effectiveness of erosion. The rocks of Little Walker are more easily affected by atmospheric agencies, and for the most part they have a much gentler dip. The Clinch Mountain gi'oup, so conspicuous in the counties previously described, comes to an end in Giles county under the influence of two anticlinals and of extensive erosion on botli sides of New river. The Medina outcrop, doubling over the anticlinals, forms Pearls and Sugar Camp mountains, while the Brushy mountain of Chemung and Vesper- tine disappears very near the line of Bland and Giles counties. But be- yond New river the anticlinals diminish and the group reappears in the magnificent pile of Butte and Salt Pond mountains, the latter rising to fully 4500 feet above tide. These mountains extend eastward into Craig county, and are conspicuously visible from localities beyond Little Walker. Wolf Creek mountain, originating in Tazewell county as a loop of Clinch mountain, extends to Pearis mountain and thence is continuous with the others. The Garden mountains unite to form the anticlinal ridge of Round mountain, which gradually disappears in the broad space between Wolf creek and Brushy mountains, known as " the wilderness." East River mountain, originating in Tazewell county, retains its name to New river, beyond which it becomes Peters mountain. Like the other Medina ridges, it is rugged and almost unbroken, the only water-gap for many miles being that of New river. The mountains, Cove and Max Meadows, in Eastern Wythe and West- ern Pulaski, are short, being cut off at each end by a fault. The area occu- pied by them is comparatively rugged and imperfectly cleared, so that little examination was made of it. Lick mountain is about fifteen miles long and is wholly within Wythe county. It lies south from the railroad, is abrupt and almost uncleared. Draper's mountain, somewhat further east, is in both Wythe and Pulaski, and is even more rugged than Lick mountain, while its length is approximately the same. Price mountain, in Montgomery county, north from the railroad, is a short, by no means abrupt ridge, which extends froni New river eastward for say eight miles, and attains its maximum at about five miles from that river. The whole region, aside from the south-west corner of Bland county, is drained by the New river and its tributaries. That great stream rises on the Atlantic side of the Blue Ridge and flows across every fold of the great Appalachian chain until, as the Kanawha, it enters the Ohio at Point Pleasant. Its most important tributaries here are Reed and Cripple creeks in Wythe ; Big and Little Reed Island, Peak and Back creeks in 18.S7.] ^" [Stevenson. Pulaski ; Walker, Wolf and Sinking creeks in Giles. Most of these streams carry much water, and for a large part of the year afford power for mills ; but the water-supply is not so regular as it was before so much clearing had been done, and floods are now too frequent. The New river, however, carries a large volume, and mills along its banks rarely suffer inconvenience. Agriculturally the features of this region do not differ from those of the area already described, except that, as already indicated, the proportion of rich land is much less. The limestone areas are those indicated on the map by the number 6, all the other portions are sandstone or shale. Much of the sandstone region is abrupt or so rugged as to be worthless for ordi- nary farming purposes, but much of the shale land lies so well for culti- vation that one feels more than regret because it is so thin. In seasons when the "rich " valleys yield twenty-five to thirty bushels of wheat, the " poor " valleys yield only from seven to ten bushels. The limestone areas are admirably adapted to grazing, as the grass is abundant and nu- tritious. The stock interests are extensive, and the cattle bring the high- est price in Baltimore, Philadelphia and New York markets. As the area described in this memoir does not reach to the West Virginia coal measures at the north, it offers a somewhat shorter list of mineral resources than do the areas previously examined. Clinton ore occurs on Big Walker, Round, Wolf creek and others of the Medina mountains, while brown hematite occurs on the southerly slope of those mountains and to some extent in the Lower Silurian limestones north from the Nor- folk and Western railroad ; but nothing is known positively respecting either the quantity or the quality of these ores. Brown hematite, zinc, lead and manganese ores occur abundantly in the southern part of Wythe, Pulaski and Montgomery counties, where the production of iron, zinc and lead has long been important. Little has been done toward developing the manganese. Coal occurs in the Vespertine along Brushy mountain in Bland county ; Little Walker in Wythe, Pulaski and Montgomery ; in the Peak hills of Wythe and Pulaski ; and in Price mountain of Mont- gomery. It has been mined to a greater or less extent at several localities in Pulaski and Montgomery. Not a little good timber remains, but the charcoal burner at the south and the portable saw-mill at the north have done much destruction without bringing much profit to the owners. The only outlet to market is by the Norfolk and Western railroad with its New River branch to the Pocahontas mines, seventy-six miles long, and the Cripple Creek branch from Pulaski to the rich mineral region of Southern Pulaski and Wytlie counties. The topography renders construc- tion of railroads difficult and costly, and the only easy line northward from the valley is occupied by the New River branch of the Norfolk and Western ; but an available route is said to exist from Wytheville over Walker mountain near the Wythe and Tazewell pike. As the mountains are in pairs a promising water-gap in one usually leads to an impractica- ble crossing of the other, and the railroad engineer often finds his wits of Stevenson.] ^^ [March 18, little service. Many routes have been surveyed in these and adjoining counties, and each new survey is an object of much interest. Some addi- tional railroads would be an undoubted convenience, as, except the pike connecting the county towns of the Great valley, the roads are not mac- adamized, and the amount of labor expended on them clearly does not exceed the minimum required by law. Those portions of this area which are underlaid by limestone are cleared and for the most part are under cultivation ; but the other portions have comparatively few settlers and are traversed by roads usually not fit for light vehicles. As a rule the people are prosperous, utilizing the advan- tages which are available, while they waste little of their energies in dis- cussing the value of the mineral wealth, which is of no immediate im- portance away from the Great valley. The villages in the valley are thrifty, have good church buildings and are well supplied with schools. The hamlets in Bland and Giles counties are very small and have little to support them.

THE FAULTS AND FOLDS The Clinch River group of faults, including the New Garden, Stone Mountain and Abb's Valley, lie north from the area under consideration. They gradually diminish eastward in Mercer county, of West Virginia, and it is doubtful whether they pass in any case much beyond the line into Summers county, of the same State. Nothing further north than the edge of the House and Barn synclinal of the last paper was reached during this reconnaissance. The geological structure of the southern part of this area is not un- known. Two sections were made by members of the Geological Corps, under W. B. Rogers, one passing through the eastern part of Wythe and Bland counties, the other through Roanoke and Craig counties, at a few miles beyond the eastern limit of the writer's study. Prof. Rogers, in his report of 1838, gave a summary account of the Vespertine coal areas. Prof. Lesley* published notes on the geology of Wythe, Pulaski •Proc. Amer. Phil. Soc, Vol. is, p. 30 et seq. PROC. AMER. PHILOS. SOC. XXIV. 135. I. PRINTED APRIL 30, 1887. Stevenson.] v)0 [March 18, and Montgomery, and Prof. Fontaine* lias given interesting details respecting the Vespertine coals. Mr. C. R. Boyd, of Wytheville, Va., has published a work, dealing with the economics of South-west Virginia, in which are given many geological details, with a map which topo- graphically is a very notable improvement on its predecessors. The writer is under obligations to these publications which will be acknowl- edged in the proper connection. The general type of structure is practically the same as that found in the areas already described, and it has been well represented by Lesley, who in his memoir on Tazewell county, f gives an ideal figure, which with his permission is reproduced as Fig. 1. The upthrow side, except in the case of cross-faults, is the south-east, and the Lower Carboniferous is found for greater or less distances in contact with the Lower Silurian limestones along most of the fractures. These faults are not simple, as is well shown in the Clinch group, but subordinate and cross-faultsdo not appear to arise directly from those of the principal system ; and where- ever a fault, either principal or subordinate, was followed out, it was found to originate or to terminate in an anticlinal. The faults are not parallel, they bear no relation whatever to the folds except such as is purely for- tuitous, and their direction is wholly independent of the strike. A regu- lar fault such as the Saltville exhibits this well, the upthrow group being in contact with different groups at different localities, owing to the influ- ence of anticlinals on the downthrow side. Some interesting facts of this kind were given in the previous memoirs ; others will be given in this, going to show independence of the faults and the folds and, as the writer intimated several years ago, suggesting very strongly a difference in age. The structure is hardly so simple as that of the counties already described and the description cannot be given in so direct a manner as that of the other counties. The Lick Mountain Anticlinal. Lick mountain, at a little way southward from the railroad in Wythe county, is due to a strong double anticlinal, which diminishes rapidly east- ward and is soon recognizable only as a gentle fold, followed by the Val- ley pike north-eastward for six or seven miles in Pulaski county. It was not traced beyond New river. How far westward it can be traced in Smyth county was not ascertained. It brings up the Potsdam in Wythe county, so as to form a very rugged mountain about fifteen miles long, but eastward it sinks so as to be crossed by the Knox shales before Reed creek has been reached ; thence, as far as it was followed, no beds below the Knox shales are shown on the axis.ij: Some anticlinals in the Knox lime- stone were seen between the Lick mountain fold and the southern edges of Wythe and Pulaski counties, but they were not followed. One is crossed by the New river, very near the Wythe lead mine. *Amer. Journ. of Science, Jan. and Feb., 1877. tProc. Amer. Phil. Soc, Vol. xii, p. 490.

At a mile and a half, or perhaps a little less, south from Reed creek on the road leading from Wytheville southward over Lick mountain, the Knox Limestones are much disturbed, being thrown into several close folds. On the Valley pike, prolmbly a mile and a half from the first crossing of Reed creek, the upper limestones of the Knox are succeeded by red shales belonging at the base of the group ; the fault rapidly de- velops and passes along the northerly side of Draper mountain, where it brings the lower beds of the Potsdam at the south into contact with the base of the Lower Carboniferous, and further eastward with the Chemung. It quickly diminishes eastward and soon is in the Knox limestone. An anticlinal is crossed by the Valley pike very near Newbern ; it may rep- resent the fault. The structure of this fault is fairly well shown at several localities, but the conditions are complicated for much of the distance by two cross- faults coming the one from the north-west and the other, if the map be right, almost from the north. A section on and near the Valley pike in Wythe county is represented by Fig. 2, but the section crossing Draper mountain near the line between Wythe and Pulaski counties, as repre- sented in Fig. 3, shows a very ditferent condition, for here the Max Meadows cross-fault is seen. The Knox limestones certainly describe an anticlinal near the fault, but whether or not they dip away at the fault could not be ascertained. /The Potsdam forms the heart of this very rugged mountain and is dipping south-eastwardly at from thirty-five to nearly sixty degrees. Further east, where the road crosses Draper moun- tain to Pulaski, the structure is as given in Fig. 4. The structure is dis- tinct along this road for the Devonian shales are turned up at the fault so as to be actually conformable in dip with the lower shales of the Pots- dam. The exposures along this road in descending the mountain are practically continuous, yet it will be found difiicult to determine accu- rately the place of the fault, so closely do the shales resemble each other and so nearly exact is the conforraability of dip. In all probability, the Vespertine is brought into contact with the lower beds of the Potsdam at a short distance west from the road, so that this is the most formidable fault yet noticed. The Pulaski fault cuts off the Devonian and Carbon- iferous, and the Lower Silurian beds are on both sides of the fault beyond Peak creek. The Area between the Norfolk and Western Railroad and the Walker Moun- tain Fault. The village of Wytheville, county seat of Wythe, is built on a ridge marking the course of the Wytheville synclinal, which, beginning cer- tainly more than six miles westward from Wytheville, extends east-north- east to where it is cut olf by the JLax Meadows fault north from Max Meadows station. A well-marked anticlinal bounds it on the southerly side, which is crossed by the Valley pike near Kent's mills, three miles Stevenson.] Oo [March 18» and a half from Wytheville, and it may be the same with that seen near Max Meadows on the railroad. It is crossed very near Reed creek on the Lick Mountain road. The dips in this portion are interesting. Within the synclinal ridge, composed of Knox Limestones, the dip is fifty to sixty degrees on both sides. The anticlinal brings up the Knox shales, which are shown on the railroad just west from Kent's mills. The south-easterly dip looking toward the Draper Mountain fault is at first very abrupt, being almost vertical for some distance along the pike, but it becomes^ gentler until the higher limestones have a dip of not more than twenty degrees. The Max Meadows fault has its origin evidently in an anticlinal, which is crossed by the Wythe and Tazewell pike at say two miles and a half from the Wytheville borough line ; it is crossed by Cove creek very near its forks and by the Norfolk and Western railroad at not far from three miles and a half beyond Max Meadows station. At a little distance fur- ther it must unite with the Draper Mountain fault. It cuts ofl:'the Wythe- ville anticlinal and synclinal at the east, while on the other side it cuts off a broad synclinal and an anticlinal which are well shown in eastern Wythe and western Pulaski and may be continuous with the Wytheville folds ; but of this, one may not speak positively. The fault becomes greater as it extends south- eastwardly at an angle with the strike, so bring- ing Hudson, Medina, Clinton, Hamilton, Chemung and Vespertine suc- cessively into contact with the Knox limestones and shales on the oppo- site side. The Pulaski fault, like the last, is a cross-fault and is the easterly boundary of the area of newer rocks held between the Walker Mountain, Max Meadows, Draper Mountain and Pulaski faults. The details of this fault were not worked out, but if the map employed be accurate, the direction from the Walker Mountain fault is almost south-south-east to Pulaski, where tlie course is changed to east-south-east. Evidently the line is south from Peak creek for more than two miles below Pulaski. Knox limestones are shown throughout on the easterly side of the fault, but on the opposite side are Devonian and Carboniferous rocks as far as followed. The region embraced within these faults was not worked out in detail, as much of it is not cleared ; but it is evident that Cove moun- tain and its Devonian companion are monoclinals and there is every reason to suppose from the exposures along the railroad that an anticlinal exists in the Peak hills, the low ridge directly north from Pulaski. The limits assigned to the several groups within this area are largely conjectu- ral. The structure of Pulaski county east from the Pulaski fault is not shown satisfactorily along the roads, but cuts along the New River branch of the Norfolk and Western railroad make the structure clear. The Knox lime- stones are badly twisted for two miles and a half from New River station, but afterwards for nearly a mile they dip quite regularly to the north-west. The dip is reversed at three and a half miles and thence for a mile the pre- 1887.) t)y [Stevenson. vailing dip is south-east, tliough tliere are some reversals. The dip be- comes very flexuous at four miles and a half, and the same beds remain in sight thence until near Belspring station, where all exposures cease. The structure may be regarded as representing two anticlinals with irregular •crests, separated by a well-defined synclinal, whose axis is somewhat more than two miles south from Belspring station. The northerly anti- clinal is cut off by the Walker Mountain fault. The faults of Price's mountain east from New river in Montgomery county hold between them a fragment of an anticlinal, the Price Moun- tain area of Vespertine coals. Between the Walker Mountain fault at the north and the northerly fault of Price's mountain, the Knox limestones ■describe a synclinal, though the few and unfortunately somewhat indefi- nite exposures show that it is complicated. The lower beds of the Knox limestone are brought into contact with Umbral red shales, but whether they are dipping to or from the fault could not be ascertained. The lime- stone on the northerly side dips northwardly at fifteen to thirty degrees, while the Lower Carboniferous rocks beyond the fault are dipping in the same direction at thirty to fifty-five degrees, the rate increasing toward the summit of the Price's Mountain anticlinal. The dip is gentler on the southerly side of the axis, rarely exceeding twenty degrees. The condi- tions at the southerly fault were not clear at the only point where it was crossed, further than that the Umbral shales and the Knox limestones are in contact. The eastward extent of these faults was not ascertained. They do not appear to cross New river at the west. The Walker Mountain Fault. This fault, following the southerly foot of Little Walker mountain, •enters Wythe from Smyth county and, at the county line, brings Knox limestone into contact with the Vespertine sandstones. The line of fault is crossed by Stony fork of Reed creek at somewhat more than six miles from Wytheville, its place being shown there by a narrow valley passing in front of the M. E. Church. The church is on Umbral shales, while Knox limestones crop out on the opposite side of the bottom. The condi- tions are the same in Crockett's cove, but in Pulaski county for several miles they are very different. There the Lower Carboniferous beds on the northerly side must be brought into contact successively with Lower and Upper Silurian, Devonian, and possibly with Vespertine near the Pulaski fault ; beyond that fault, Knox beds occur again. Tlie fault-line passes but a little way south from the Altoona mine ; is crossed by the Dub in and Pearisburg pike at half a mile, possibly a little more, north from Back creek ; by New river just below the mouth of Back creek ; and by the Newport and Christiansburg road at only a little way south from Tom's creek : in each case bringing the red Umbral shales into contact with the lower limestones of the Knox group. Generally speaking, the structure in the vicinity of this fault is simple, and notwithstanding the enormous vertical extent of the fracture, the Stevenson.] « " [March 18, crushing and distortion are very much less than that observed near the Kew Garden fault in Tazewell county, the Hunter valley fault in Russell, or even the Max Meadows fault on the railroad. Where crossed by the Wythe and Tazewell pike it shows dips of thirty to forty degrees in the Lower Carboniferous, and forty to fifty-five degrees in the Knox limestones at about equal distances from the line of faulting ; on the Dublin and Pearisburg road, the dip is comparatively gentle and the succession of Lower Silurian on top of Lower Carboniferous appears to be wholly con- formable ; a similar condition exists on New river, where the dips in the Umbral shale near the fault are only ten to fifteen degrees, while in the Vespertine further from the line the dip rises to fifty-five degrees. Here, however, the rocks on the southerly side are disturbed, and the beds are wrinkled for a mile or more. Near Tom's creek the greater disturbance is on the northerly side, where the Lower Carboniferous beds are almost vertical, though dipping toward the fault, while the Knox limestones are dipping much less sharply in the same general direction. The structure between the Walker Mountain and Saltville faults is much less complicated than that of the next block southward. The Vespertine Coal group is exposed continuously on the northerly side of the former fault from eastern Smyth to beyond the centre of Montgomery county, and the course of the fault is -so little ofi the strike of the beds that the thickness of the overlying Umbral shales shows very little change from Wythe county eastward. Big Walker mountain is a Medina ridge sepa- rated by a Clinton and Hamilton valley from Little Walker mountain, an Upper Devonian ridge with Lower Carboniferous sandstones and shales on its southerly slope. The dip throughout, or nearly so, is south of south-east at from ten to sixty degrees. Petty wrinkles occur in the shales, but the only material interruption of the dip on Big Walker is near the Tazewell pike, where at barely five or six miles from the Smyth county line an anticlinal evidently has its origin. This rapidly increases eastward and soon causes a considerable southward deflection in the Medina out- crop or. crest of Big Walker mountain. The axis must be cut several times by Walker's creek, which flows on Knox limestone along the northerly foot of the mountain ; and the fold shows no material decrease until beyond the line of Bland county ; but thence to New River gap, the Medina of Walker mountain gradually approaches the Saltville fault. The interval between that fault and the Medina opposite Seddon is fully three miles, but at New River gap it is barely one mile. The dips on the northerly side of Big Walker are comparatively gentle except for a few miles on each side of the New River gap ; and it is worthy of notice in this connection that the dips throughout Big and Little Walker along the New river are much more abrupt than at any other localities. Possibly the approach of the Medina outcrop to the Saltville fault may be due as much to a thrust as to diminished strength of the Walker Creek anticlinal. 1887.] '1 [Stevenson. The Saltmlle ^ault. This interesting fault, originating in Tennessee, enters Bland county- just north from the Saltville and Sharon Springs road ; passes at only a few rods north from that road at Sharon Springs ; less than one-third of a mile north from the cross-roads at Seddon ; lies north from the road for six miles beyond Seddon ; thence for two miles is south, but is again crossed so that it is only a few rods north from the forks of the road at Poplar hill, in Giles county ; it is crossed by New river in Buckeye moun- tain, very near Scott's ferry ; and by the Salt Pond and Newport road in a wind-gap through Buckeye mountain at half a mile north from New- port. The dips of the southerly side are regularly south south-eastward, and not very abrupt, rarely exceeding twenty five degrees ; those on the northerly side are equally regular except near Newport, where the Trenton shales are faulted against the Knox limestone and the former are badly twisted. The Knox limestones are shown on the southerly side of the fault, and notwithstanding the great variations ot horizons on the northerly side, there is comparatively little change on the southerly side — even less than might be expected from the influence of the Walker Creek anticlinal. The variations on the northerly side possess much interest, but being due to the Clinch Mountain group ot folds cannot be described until after those folds have been discussed. The Clinch 3fountain Qroiif of Folds. Where tirst seen, in Scott county. Clinch and its associated Brushy mountain make up a broad monoclinal, showing a section from Medina on the crest of Clinch mountain to tlie highest Umbral rocks at the Saltville fault. The width of Upper Silurian and Devonian is barely three miles. In Smyth and Tazewell, however, a fold, the Burk's Garden anticlinal, arose at the foot of Clinch mountain, widening the area of Silurian and Devonian, and narrowing that of the Lower Carboniferous until at the line of Wythe county only the Vespertine remains. Similarly, gentle folds in Russell and Tazewell interrupt the dip at the north and the Medina outcrop is carried further in that direction, so that Rich mountain, whose crest is merely the continuation of Clinch mountain around a petty anti- clinal, lies nearly a mile north from the previous line of Clinch. So the monoclinal of Scott county is interrupted by a great fold with a broad synclinal at the north as it enters Bland county. The structure becomes more complicated within Bland and Giles, but gives promise of returning simplicity as the group passes into Craig county beyond the limits of the writei-'s examination. The Burk's Garden fold, which attains its greatest maximum in the cove of that name, quickly flattens, so that at the easterly end of the cove, the Medina outcrops of Garden mountain unite and that sandstone crosses the fold in Round mountain. The decrease is so rapid that within five miles Stevenson.] ' ^ [March 18, the Hamiltoa crosses the anticlinal, which at four miles further eastward seems to have disappeared. The Pearisburg synclinal, between the Cove and Elk Garden anticlinals in central Tazewell county, lies between the Elk Garden and Burk's Garden anticlinals in eastern Tazewell, owing to the disappearance of the Cove fold. Wolf creek, rising in Burk's Garden, flows for more than fifteen miles in this synclinal within Bland county, so that Rich mountain of Tazewell, continuous with Clinch mountain further west, becomes Wolf Creek mountain of Bland county. The disappearance of the Burk's Garden fold and the rapid growth of the Kimberling anticlinal keep this trough distinct to beyond the eastern limit of Giles county. Brushy moun- tain, the Devonian ridge with Vespertine foothills, continues to about the eastern border of Bland, where under the increasing influence of the new anticlinals the mountain gradually disappears. The Kimberling anticlinal was first observed on the Seddon and Mercer county road, where, though narrow, it is distinct at not far south from the summit of Brushy mountain. To the influence of this anticlinal, most probably, is due the widening of the Vespertine area further west as shown on the road crossing Brushy mountain to Hunting Camp creek. The "Wilderness" road, leading from Kimberling creek to Rocky gap, crosses the anticlinal at say a mile* from the junctitm of Kimberling with No -Business creek. This fold, rapidly increasing in height, causes the broad space of Devonian shales, known as the "Wilderness," which extends from Brushy mountain northward almost to the foot of Wolf Creek mountain. It soon brings up the lower rocks and the Medina in crossing it forms a long V, with the opening toward New river. The northern arm, known as Pearls mountain, reaching north-north-eastward into the Pearisburg synclinal, terminates in a peak — the Angels' Rest — near Pearisburg, where it bends on itself and becomes continuous with Wolf Creek mountain. The southerly arm is Sugar Run mountain, point- ing out in the synclinal between Kimberling and a new anticlinal, the Sinking Creek, which first appears along the Saltville fault at a little way east from the Bland county line. The Kimberling anticlinal attains its maximum elevation between Walker creek and the Dublin and Pearisburg road, whence it diminishes rapidly toward the north-east. Erosion has been effective on both sides of New river, so that for several miles Lower Silurian limestones are the immediately underlying rocks. But the comparatively rapid flattening of the Kimberling anticlinal per- mits the Medina to appear in the Pearisburg synclinal with double out- crop as Butte mountain at, say four miles eastward from New river. The course of the fold and its loss of elevation are shown by the deep re-en- trant angle between Butte and Salt Pond mountains. The latter is the double outcrop of Medina in the synclinal between the Kimberling and *Many of the distances given in this memoir were determined by "dead reckoning," there being no other means of making determination in the thinly settled portions.

Sinking Creek anticlinals, but it does not extend so far westward as Butte mountain, for the Sinking Creek anticlinal attains its maximum at a little way eastward from Xew river and Medina does not cross it until very near the easterly line of Giles county. This fold is crossed by the Salt Pond and Newport road at barely two-thirds of a mile north from Sinking creek. For the most part the dips in the synclinals are not very abrupt ; but the "Wilderness" road in crossing the Pearisburg synclinal shows Chemung with fifty degrees northerly, and almost vertical southerly dip. Northward the dip diminishes, for in Rocky gap through Wolf Creek mountain the Medina shows only twenty-six degrees. Further eastward in this trough, at the end of Butte mountain, the calcareous shales of the Trenton have been thrown into numerous and very narrow flexures. A similar condition exists in the Salt Pond synclinal on the Salt Pond and Newport road where some of the petty folds show distinct faults. The effects produced by the Saltville fault in cutting across the south- erly slope of the anticlinals are shown by the map. As the Burk's Garden anticlinal diminishes, the width of the Lower Carboniferous area increases, so that at Sharon Springs the Umbral red shales appear ; but as the Kim- berling anticlinal increases, the width diminishes and the whole of the Lower Carboniferous is finally lost in the fault near the Giles county line. Devonian, Upper Silurian and the upper beds of the Lower Silurian are cut off quickly at a little way further east under the added influence of the Sinking Creek anticlinal and of erosion by Walker's creek and New river, so that for several miles east and west from Poplar hill, the fault is in Knox limestone. Thence north-eastwardly to the county line, Medina is found on the northerly side of the fault, except at New River gap and for a few miles on each side of Sinking Creek gap, where erosion has cut away both Medina and Hudson. Knox limestone is continuous on the southerly side of the Saltville fault from the Smyth county line to the end of Giles county. It is in contact with Lower Carboniferous in Bland, with Chemung, Hamilton, Clinton, Medina, Hudson, Trenton and Knox within eight miles eastward from the line of Giles county ; and with Medina, Hudson or Trenton, according to extent of erosion, thence to the end of the region examined. The rela- tions are shown in Figures 5, 6 and 7, which are merely diagrams, not actual measured sections. The Elk Garden Anticlinal and Wolf Creek Faults. The Elk Garden anticlinal of Russell and Tazewell counties gives rise to the Copper Creek fault in western Russell. The anticlinal continues in eastern Tazewell between Wolf Creek and East River mountains to within less than four miles of the Bland county line ; but at some place between that and two miles west from Rocky gap in Bland county it gives rise to a double fault, the Wenonah, which was followed to within eight miles of the Craig county line. Another fault, that of Buckhorn mountain, origi- PROC. AMER. PHILOS. SOC. XXIV. 125. J. PRINTED APRIL 30, 1887. Stevenson.] *^ [March 18, nates nearly opposite Rocky gap or Wolf Creek gap, through Wolf Creek mountain, where it cannot be more than a few rods distant from the Wenonah. This was followed to somewhat less than twelve miles east from New river. But both faults must extend several miles further than the writer's examinations went. The Wenonah fault, whose course is shown by the Valley ridge of Wolf Creek valley, is crossed by Wolf creek at a little way below Rocky gap, but not again except, perhaps, above the " round bottom ;" it is crossed by New river At Wenonah ; is touched by Big Stony creek at one mile from the river, and its peculiarities are well shown at three miles from the river on the road leading from Big to Little Stony creek. Where first seen, this fault is in Knox limestone and holds a wall of Medina and Clinton in its jaws. As one comes fi'om the " Wilderness " through Rocky gap of Wolf Creek mountain, he finds the complete succession from Medina to Knox limestone ; but within a mile below the gap he reaches the fault. There the creek breaks through the Valley ridge, in which Medina is shown with dip of eighty degrees, while on the lower, as on the upper side of the ridge, Knox limestone is shown against the Medina. The wall of Medina is wanting at Wenonah, where the fault shows Knox on both sides. The Valley ridge shows two sets of faults instead of one at three miles east from New river, where two lines of Medina are present. The Buckhorn fault, whose course is shown by Buckhorn mountain and Little mountain, a ridge following the southerly foot of East River and Peter's mountain, is crossed by the Wolf Creek road after passing through the Valley ridge, nearly one mile below the Rocky gap. It is recrossed on the hill overlooking Mr. Carpenter's house at say two miles and a half frohi the gap. Thence, neither road nor creek touches the fault, though they approach it closely at the Giles county line. It brings Medina or Clinton into contact with Knox limestone. The lines of faulting are not exposed. A reversed dip is shown on the north side of the Wenonah fault at one locality on Big Stony creek ; and the Medina shows a flexure on the southerly side in the Wolf Creek gap through the Valley ridge ; so that there is evidence of dragging at both localities. The dips in the intervals between these faults rarely exceed forty degrees and ordinarily are between twenty and twenty-five degrees. The interval is but a few rods wide at the gap through the Val- ley ridge, but beyond the New river it is nearly two miles. The faults disappear at no great distance beyond the limits of the writer's examina- tion, for in the Rogers section, an anticlinal is shown along the foot of East River mountain in Craig county.

The valley between these ridges is reported to show only shale. The Clinch FaxdU. The Clinch River system of faults continue from Tazewell county into Mercer county of West Virginia, which lies beyond tlie area examined for this memoir. The New Garden fault passes at a little way north from East River mountain and continues eastwardly beyond the eastern limit of Mercer county, as appears from the Rogers' section ; but it is greatly diminished in eastern Mercer, for there it is in Devonian rocks, whereas in Tazewell it brings Quinnimont into contact with Knox lime- stone. The Stony Ridge and Abb's Valley faults certainly disappear before the eastern line of Mercer county is reached, unless their course has been greatly changed, for the writer found no trace of them in Summers county, of West Virginia, where they should be found. The extreme vertical extent of the several faults is approximately as follows : Draper mountain 12,500 feet.

The section is a long one, reaching from the Umbral of the Lower Car- boniferous to the lower beds of the Potsdam. No detailed measurements were attempted and in most cases no effort was made to estimate thick- nesses. Only the more general features are summarized here, as most of the details given in previous memoirs are equally applicable to this area. The, Carloniferoiis. The Coal Measures are not reached but the Lower Carboniferous is repre- sented by the Umbral and the Vespertine. These groups are shown in Bland county along the southerly slope of Brushy mountain ; in Wythe, Pulaski and Montgomery counties, they form the foothill of Little Walker mountain ; they are present in Wythe and Pulaski counties in the area between the Max Meadows and Pulaski faults ; and in Montgomery, on Price mountain. The Umbral. — Prof. Fontaine makes the thickness of the upper portion, the Umbral red shales and shaly sandstones, to be 1090 feet in Brush and Price mountains of Montgomery county, and the writer finds 996 feet in the New River gap through Brush or Little Walker mountain. In the Memoir on Lee county, &c., the writer regarded these Montgomery county shales as Vespertine, but he now feels that that identification is 7fi Stevenson.] • ^ (March 18, erroneous and that the shales belong to the Umbral or Greenbrier series. These shales are well shown on the various roads crossing Brushy moun- tain in Bland and especially well along the various roads crossing Little Walker, in Pulaski and Montgomery counties. They occasionally con- tain a thin bed of coal, which was seen on Brushy mountain, in Bland, and on the Norfolk and Western railway near Clark's summit, in Pulaski county ; but the bed is of no importance. The rocks are reddish shales, mostly sandy, occasionally compacted into earthy sandstones ; but in nearly all cases the bedding is irregular. So far as observed, these beds are not fossiliferous. A silicious limestone, too impure to be used in making lime, occurs under these shales. It is said to be seven or eight feet thick on Stony Fork of Reed creek, in Wythe county : it is rather less on the railroad in Clark's summit cut four miles and a half east from Max Meadows ; and is a little thicker on Brushy mountain, in Bland county. In many ways this is exceedingly suggestive of the silicious limestone which occurs at the summit of the Vespertine in Pennsylvania and it maybe the represen- tative of that rock. This limestone the writer takes to be in all proba- bility the separating bed between the Umbral and the underlying Vesper- tine, but with greater affinity with th? latter. Unfortunately, the only locality where measurements can be made without great expenditure of time is along New river, but there the limestone was not recognized and an arbitrary line had to be assumed for separation of the two groups. The variations in the Umbral within South-western Virginia are not without interest. The section obtained in Lee county showed 1. Shales and sandstone with thin limestone 705' 3. Limestone and calcareous shales 150' 3. Cherty limestone 200' In Brushy mountain of Washington county on north side of the Salt- ville fault, the upper division retains its thickness while the lower divi- sions increase vastly, the measurements being. No. 1 800 feet. No. 2 1470 " No. 3 605 " But in western Smyth county, where the group is crossed by the road leading to Saltville through Brushy mountain, there is manifestly a seri- ous decrease in thickness of the limestones, while tlie shales appear to have decreased very slightly. Within Bland county, in the same moun- tain, the red shales are found thick, but the limestone has disappeared. This is simply the condition which one should expect to find here, when it is remembered that on the north westerly side of the Great Valley in Pennsylvania and Maryland, limestone is found almost wholly absent from the isolated patches of Umbral : similarly, with the disappearance of the calcareous matter, the fossils disappear. Prof. Fontaine came to the same conclusion with respect to the relations of these shales after com- 77 1887.] * * [Stevenson. paring them with the section obtained near Lewisburg, in Greenbrier county, of West Virginia. The Vespertine. — This great period is represented by sandstones and shales witli coal beds, having in all an extreme thickness of not far from seven hundred feet. The bottom of the group is taken to be a grayish sandstone, sometimes slightly conglomerate, often with impressions of SpiropJiyton, and about thirty feet thick. It is a characteristic rock rest- ing directly on sandy beds which mark the transition to Chemung and in which the dividing line cannot be dra»vn very closely. On this sandstone rests the succession of shales and sandstones, the latter varying from gray to blue or red, from compact to shaly, from good building stone to miser- able rubbish. The general succession is fairly well shown in many of the smaller gaps through Brushy mountain of Smyth and Bland, as well as in the similar gaps through Little Walker in Wythe, Pulaski and ]\Iont- gomery ; a more accessible section is along the Norfolk and Western rail- road for seven or eight miles west from Pulaski. The change in this group is as marked as that in the Umbral. The sec- tion in Lee county shows Reddish silicious beds, some shale 150 feet. Some part of which must represent the Vespertine. No coal was seen here. In the North Holston section near Mendota, in Washington county, the Vespertine can only be in the concealed space of eighty feet at the bottom. But the sandy beds increase toward the north-east so that before the line of Smyth county has been reached a coal has been mined in the river bed, while the shales and sandstones form a notable foothill to Brushy mountain. At the Laurel gap, in Smyth county, the estimated thickness is about 500 feet, while in the same ridge within Bland county, the thickness appears to be approximately the same. But followed north- westward into Tazewell county, this division is found insignificant wheie shown among the Clinch faults, being thinner on Indian creek than in Pennington's gap, in Lee county. Along the foot of Brushy and Little Walker mountains, one finds the Vespertine very much as in South-cen- tral Pennsylvania, a mass of shales, sandstones and irregular coal beds, capped by a silicious limestone. The feature of especial interest is the great development of Vespertine coal beds within Wythe, Pulaski and Montgomery counties. These have been worked, especially in Montgomery county, for many years, and a summary account of them was given by Prof. W. B. Rogers, in his report for 1838. Prof. J. P. Lesley gave an excellent statement respecting the beds and workings as they existed in 1860 ; while Prof. Fontaine has described in detail the beds of Brush and Price mountains, in Montgomery county. According to Capt. Boyd, thirteen beds or streaks of coal occur in a ver- tical space of less than 400 feet within the gap made through Little Wal- ker mountain by Stony Fork of Reed creek. The first five of these beds are embraced within a column of 100 to 130 feet, No. 1 resting on the Stevenson.] * ^ [March 18, sandstone, known as " Quarry rock, " which the writer has assumed as the base of the Vespertine. The first three beds alone possess any economic interest, as no others are mined anywhere within this region. The lowest bed is usually very thin, but on Cloyd's mountain in Pulaski, and on Brush mountain in Montgomery, it becomes of workable thickness, two and a half to three feet. The second bed has been opened near the Wythe and Tazewell pike in Wythe county ; at the Altoona mine in Pulaski ; at several places along Tom's creek in Montgomery, all in the foothill of Little Walker or Cloyd's or Brush mountain, as the ridge is termed in different portions of its extent. Apparently the same bed has been mined near Sharon Springs, in Bland county ; and on Price's mountain, in Montgomery. It varies from nearly four feet of nearly solid coal in Wythe to twenty-two feet of shale and coal in Pulaski, and nine or ten feet of coal and shale in Montgomery. But these are extreme measurements and the bed exhibits great and sudden variations in thickness, owing to the im- mense pressure which the yielding material has suffered. A similar con- dition exists in Bland county ; but the variations in Price's mountain are comparatively small. The third bed was mined systematically onlj' at the Altoona mine in Pulaski, though it was opened in Wythe county, near the Wythe and Tazewell pike. Its thickness at these localities is said to be between three and four feet. It is not worked now. The physical structure of the coal shows great variations, which cannot be accounted for always by supposing different degrees of pressure. The coal from the second bed appears everywhere to have undergone much greater change than either the first or the third. In Wythe county at the Boyd mine, in Pulaski ; at the Altoona mine and on the Dublin and Pearisburg road ; and in Montgomery county, on Tom's creek ; as well as in Bland county, near Sharon Spriags, the coal from the second bed appears to have been crushed into fragments, which f§ere pressed and rubbed until they were reduced to lamina?, so loosely packed in many places as to be easily separable by the fingers. But the coal of the first or third bed may be found on the same hillside, hard enough to bear transportation, though it shows with sufficient distinctness that it too has been subjected to severe crushing and rubbing. It has been broken into fragments, which have been rubbed together until thoroughly glazed. But the rubbing did not reduce the fragments to laminae. This variation may be due to difference in chemical composition or to the fact that the thinner beds are not broken by shale partings. It is of interest, however, to note that notwithstanding all this crushing and rub- bing, the penetration of coal layers by shale layers in the second bed is no greater than that often seen in coal beds within the very little disturbed Coal Measures area of South-western Pennsylvania and the adjacent parts of West Virginia. The crush of strata in Price's mountain has been comparatively slight, despite the faulting, though there also, it is suf- ficiently clear that the greater part of the crushing was endured by the <;oal, as being the more yielding substance. 1887.1 79 [Stevenson.

Much of that from Tyler's mine near New river is used as grate fuel in villages along the railroad west from New river. The Tom's Creek mines are worked and the coal is carried in wagons nine or ten miles to Bang station, on the railroad, whence, witli the Price Mountain coal, it is distributed to villages in the vicinity. In spite of the great percentage of ash and the much higher cost per ton, the Tyler and Price Mountain coals are preferred to Pocahontas coal for grates, as they are practically free-burning, having very slight tendency to coke. The Altoona coal is used at the salt-works in Smyth county, and at the Bertha zinc-works in Pulaski. A comparison of the fuel ratios is interesting.

These analyses show that the proportion of the volatile combustible mat- ter decreases north-eastward, so that one is prepared to find not a semi- bituminous coal such as these, but a true anthracite in Narrowback moun- tain at the Dora mines further north-north-east, near Harrisonburg. The material for comparison of the areas lying further south-east, in the Valley, does not exist. No analyses of coals in the area between Max Meadows and Pulaski have been made, so far as the writer knows ; only one analysis of the Price Mountain coals by McCreath, and one of the Catawba coal in Botetourt county by Rogers, have fallen under the writer's notice ; these show : Price mountain 13 87 Catawba 21 79 a very notable difference. "Whether or not the specimens were taken from different parts of the same bed or from different beds cannot be ascertained. The Vespertine coal beds attain their chief importance within the coun- ties of Wythe, Pulaski, Montgomery, Roanoke and Botetourt, a distance along Little Walker mountain of barely 105 miles. But isolated patches of slight extent preserved in synclinals within Augusta and Rockingham counties, show that the field with beds of workable thickness extended to certainly 100 miles further north-north-east, thus giving a length directly measured of nearly 200 miles. Exposures in Wythe, Pulaski and Roanoke show that the Vespertine beds reached far into the area now known as the "Great Valley," fragmentary patches still remaining at a distance of barely twelve miles from the Archtean, while exposures in Bland and Rock- ingham show that the productive coal area in Virginia extended to some distance beyond the line of the Saltville f;iult. Certainly it was 200 miles long by fifteen miles in Virginia ; and the width may have been twelve miles greater toward the south-east, reaching to the Archi^an. The whole area may be estimated at beyond 5000 square miles, of which only insignificant strips and patches have escaped erosion, amounting in all to not more than 130 square miles. How much further north-eastward this area extended cannot be determined, for in Pennsylvania and Maryland the numerous folds with the disappearance of the faults have thrown the most easterly outcrop of Vespertine, to a distance from the Archaean greater than that of the Abb's Valley fault from the Archnean in Virginia. No workable coal beds occur in Pennsylvania and Maryland within the Vesper- tine, but what existed in that portion of the Vespertine which has been removed by erosion, we may conjecture from the conditions occurring in Virginia within the same space. Within Virginia the coal beds diminish quickly in importance in all direc- tions from the area already defined. South-westward, the coal-bearing division of the Vespertine diminishes and the last trace of it occurs on the North fork of Holston, near Mendota. in Washington county, where coal is said to be found'in the river-bottom at low water. North-westward 1887.] ol [Stevenson. the coals diminish. In Lee, Wise, Russell and Tazewell counties, of Vir- ginia, this lower division is either insignificant or wanting — but further north-west, in Greenbrier county, of West Virginia, Prof. Fontaine* found the sandstone division with strings and beds of coal, which, however, are interesting more because of their existence than because of any economi- cal importance. The total thickness of the whole series there is about 290 feet. No Vespertine is found in or immediately adjoining the Great valley, beyond Augusta county, of Virginia ; but the petty areas preserved on the crests of synclinal ridges are among what Prof. W. B. Rogers termed the Allegheny mountains, in Hardy, Hampshire and Morgan counties, ot West Virginia. There the coals are usually very thin, as they are also under the great anticlinals of Randolph and Tucker counties, of West Vir- ginia, Allegheny county, of Maryland, Bedford, Huntingdon, and the counties further north in Pennsylvania. The coal is present in all of these, but not in such shape as to deserve more than passing notice ; the thick- ness seldom exceeds a few inches and the large percentage of ash leads most persons to regard the coal as anthracite. Along the lines mentioned, the sandstones show a decided thickening, becoming 1100 feet or more in Bedford county, of Pennsylvania ; but the thinning is very marked in a north-westward direction, as the whole thickness in Fayette county, of Pennsj^lvania, is barely 400 feet. There, the last westward exposure on the easterly side of the Appalachian region, it appears to contain no coal. The Devonian. The Devonian is represented by Chemung and Hamilton only, the Cats- kill and Carboniferous being absent. In Bland and Giles counties Devonian rocks occur in the "Wilderness" area of Kimberling creek, and they make up the great part of Brushy mountain, in the former county ; they underlie the "Poor valley " of Walker mountain, and make the mass of Little Walker and Max Meadows mountains, while a narrow strip lies along the north side of the Draper Mountain fault in Pulaski county. Except in the " Wilderness," where the Oriskany was recognized, no line could be drawn between Devonian and Upper Silurian, the shales of the one passing interceptibly into tlie shale of the other. Ghemung. — The Chemung, as seen on the North Holston near Mendota, is 350 feet thick, but it is wholly absent from Stony mountain in Lee county. Eastward, or rather north-eastward in Brushy mountain, the thickness in- creases rapidly, so that north from Saltville, in Smyth county, it is cer tainly twice as great as at Mendota. On the same mountain, in Bland county, the increased thickness is noticeable even to the most careless ob- server, and on the road leading from Walker creek to Hunting Camp creek, the following succession was seen : 1. Sandstones with some shales. 2. Conglomerate sandstone. * Loc. eit. , pp. 44 and 45. PKOC. AMER. PHILOS. SOC. XXIV. 125. K. PRINTED APRIL 30, 1887. Stevenson.] ^-' [March 18, 3. Shales and sandstone. 4. Conglomerate sandstone. 5. Shales and flags. No eflfortwas made to secure measurements here, as the road is tortuous and in unbroken forest, but an excellent section can be obtained by instru- mental measurement, as the stream bed affords almost continuous expo- sures below the upper conglomerate. The flaggy sandstones between the conglomerates are bluish red and resemble closelj^ the rocks immediately overlying the upper conglomerate ; but details respecting the great part of No. 1, which includes beds of passage from Vespertine to Chemung, are practically wanting here. In the Laurel Fork gap tlirough Brushy mountain in Smyth county, and in the Seddon gap in Bland county, these are shown to be gray to blue sandstones. The section is similar in the Little Walker mountain gaps. On New river the distance from the "Quarry rock" to the conglomerate is not far from 900 feet, but no exposures occur in the interval along the railroad. Almost continuous exposures on the Newport and Christiansburg road show the space to be filled with gray to yellowish flags and sandstones with few shales. At all localities the beds of No. 3 consist of more or less argillaceous concretionary sandstones passing downward into shales with bluish led or deep red flaggy sandstone. The flags, though forming a small part of the mass, are sufficiently hard to support the cliffs of this division, which are seen in many ravines. These beds are well exposed on all graded roads crossing Brushy and Little Walker mountains ; along the ravine followed by the road to Hunting Camp creek, in Bland, they are shown in cliffs. There, however, the flags appear to be more abundant than at any other locality. No satisfactory estimate was made of the thickness, but as ex- posed along the Hunting Camp road, in Bland, it is not less than 1000 feet. No. 5 consists of flags and shales, olive, gray, blue and drab, which are well shown at many localities. The conglomerates are rarely shown in place. No. 2, which is not far from forty feet thick on Brushy mountain aud is certainly much thicker in Little Walker, was seen in place only on the road to Hunting Camp creek, on New river and on the Newport and Christiansburg road over Little Walker, yet this conglomerate is the "backbone " of both moun- tains, and to its ragged outcrop is due the irregular crest of each. Its fragments are always abundant and ordinarily they are characteristic. The pebbles vary in size from a ijea, to a hen's egg ; while in several of the layers they are flat and, curiously enough, in some parts their longer axis is almost vertical to the plane of bedding. Almost without excep- tion these are of quartz or quartzite. The lower conglomerate was seen in place only on the Hunting Camp Creek road in Bland county, just where the road leaves the long gorge and emerges upon the "clearing." In general features it closely resembles the upper conglomerate. 80 .u^,.j '^ [Stevensou In the New River section fragments with Chemung fossils are plentiful to a vertical distance of not far from 500 feet above the conglomerate, but beyond that the fossiliferous fragments become rare and soon are alto- gether wanting. A fossiliferous sandstone containing Ghonetes and Pthonia, both Chemung forms, together with many other forms not easily recognizable on the weathered surface, was seen on the Dublin and Pear- isburg pike at between 300 and 400 feet vertical distance above the sup- posed place of the upper conglomerate. The transition tlience to the Ves- pertine, as shown in the excellent and almost continuous exposures along that road, is absolutely imperceptible — there is no change to the "Quarry rock," and the drawing of the line of separation at the bottom of that rock is wholly arbitrary here. But at many other localities a change occurs at about 200 feet below that rock, bringing in some bluish sandstones. Che- mung forms become very abundant immediately below the upper con- glomerate. Good collections can be made on Brushy mountain in Bland county along the Seddon and Mercer road, as well as along the road from Point Pleasant to Kimberling creek. Excellent localities on Little Walker are on New river and on any of the roads crossing the mountain in Pul- aski and Wythe counties. No doubt good collections can be made within a mile and a half of Pulaski on the road leading over Draper mountain. The geologist familiar with the Chemung of Pennsylvania and Mary- land will recognize a familiar section here : the two conglomerates with variegated shales below them passing into' the flags, while between them are the flags and shales passing through clayey concretionary sandstones to the upper conglomerate. The similarity fails above that conglomerate in that the red shales are wanting, and the passage to the Vespertine is through sandstone rather than through shale. The condition is more nearly that of South-western Pennsylvania where, as here, the Catskill is absent and the Chemung is carried directly to the Vespertine. The thick- ness of the section in Bland county appears to be very nearly the same with that of the section in northern Bedford county of Pennsylvania, nearly 300 miles away along the line of strike. This persistence through so great a distance makes more remarkable the entii"e disappearance of the group between Bland Court-house (Seddon) and Pennington's gap in Lee county, only 125 miles away at the south-west. This group evidently reached to the south-easterly side of the "Great valley," for the beds upturned alongside of the Draper Mountain fault are within twelve miles of the Archisan. Hamilton. — The line between Hamilton and Chemung cannot be drawn satisfactorily during a reconnaissance, as the passage from one to the other is by no means abrupt. So gradual, indeed, is the passage here, as well as in a great part of the Appalachian region, that the older geologists of both Virginia and Pennsylvania placed the series together as a single group, their No. VIIL The Hamilton shales are gray to black, and evidently represent only the lower part of the group as found further northward. They are shown in the " Poor valleys " of Walker and Cove mountains. Stevenson.] O^ [March 18, as well as in Bland county around the foot of Round mountain. They contain little of interest. The Upjjer Silurian. No definite line of separation between Upper Silurian and Devonian could be made out except in the " "Wilderness " area of Bland and Giles counties ; there the Oriskany is present, which makes the boundary dis- tinct. Upper Silurian, represented by Oriskany, Clinton and Medina, makes up the most prominent features of the district, Medina being, par exeellence, the mountain -making rock. The Oriskany was seen only in Bland county, where it is exposed at the foot of Round mountain and the Garden mountains, as well as along the foot of Wolf Creek mountain in the "Wilderness." The rock is a thin sandstone, which resists the weather so well as to make a small ridge. If this rock be present in the "Poor valley " between Big and Little Walker mountains, it must be very thin and must yield readily to the weather, as that valley was crossed on four lines, each aftbrding good exposures, but without Oriskany. As shown in the " Wilderness " the rock is a moder- ately coarse gray sandstone, evidently not more than ten feet thick, and containing, in addition to the ordinary forms, impressions of large crin- oidal joints. The Lower Hclderherg may be present in the "Wilderness," but no pos- itive proof exists. Fragments of white chert containing a delicate Stro- matopora, and seen near Round mountain, have much resemblance to the chert bed at the base of the Oriskany or top of the Lower Helderberg. Aside from those fragments nothing referable to the Lower Helderberg was seen in any of the " Poor valleys." The Clinton forms a bench around Round mountain ; on the Garden mountains ; on Wolf Creek mountain and its continuation in Pearis and Sugar Run mountains ; ou Big Walker and Cove mountains. Everywhere it presents the same features, variegated shales with white sandstones near the ores. The "fossil'' ore occurs, but little only is known respecting either its quantity or quality. It appears to be abundant, though silicious, on Wolf Creek mountain, if one may judge from the fragments where the ore horizon is crossed by the I'oad near Wolf creek or Rocky gap. The Medina is well known as the mountain-making rock. Its outcrop forms the crest of Cove, Big Walker, Garden, Round and Wolf Creek mountains ; it makes a double outcrop on Pearis and Sugar Run moun- tains, as well as on Butte and Salt Pond mountains ; while it is shown on each side of the House and Barn synclinal in Buckhorn and East River mountains. The Upper or White Medina is very far from being coarse, though a few layers of conglomerate were observed in it. The best exposure is in the gap made by New river through Big Walker mountain, where the estimated thickness is 375 feet. For the most part the rock is white, and on long exposure the surface becomes beautifully polished. This is char- 1887.] ^^ [Stevenson. acteristic of the rock along an outcrop of fully 400 miles. Some brown or reddish-brown layers occur in this division, but their thickness was not ascertained. Aside from ArthropJiycus liarlani and a 8colithus-\\\<.Q form, no fossils occur in the sandstone. The Lower Medina, composed of reddish sandstones and shales, is the imperfect terrace on the northerly side of the mountains, and, as was stated in a previous memoir, this is clearly the same with the Terrace group of South-central Pennsylvania, which has been identified by Lesley, and therefore by the writer in his Pennsylvania report, as the Red Medina of New York. The thickness cannot be given with any degree of cer- tainty, as the rock passes downward without break into the Hudson ; or- dinarily it is much disturbed. The best exposure in detail is on the Taze- well and "Wythe pike as that road descends the northerly side of Big Walker mountain toward Sharon Springs. There, within 100 feet verti- cally below the White Medina, is a fossiliferous bed, six to eight feet thick, containing Bhynchonella, OrtJiis, Modiolopsis, Avieula emacerata, Ambo- nyeliia rciMnta and fragments of Orthoceras, which were collected during an examination lasting but a few minutes. The relation to the Lower Silurian, therefore, is intimate, so intimate that the writer is more tlian ever convinced that there is room for doubt- ing the accuracy of any identification which makes the Terrace group of Southern Pennsylvania the equivalent of Medina in New York. The Lower Silurian. The Lower Silurian is represented by Hudson, Trenton and Knox lime- stone. Hudson beds occur only on the steeper slopes of the Medina mountains ; Trenton is at the foot of such mountains, but within the counties described in this memoir, is rarely seen in the broader limestone valleys. The Knox limestone is the surface group in the "Rich valley" of Bland and Giles ; on both sides of New river in Giles* county ; and is the great limestone group cropping out over so macli of the " Great val- ley " in Wythe, Pulaski and Montgomery counties. The Hudson consists of red to yellow sandy shales, which pass with equal indefiniteness into the Red Medina (?) above and into the calcareous shales of the Trenton below. The Trenton beds are calcareous shales with streaks of impure limestone passing downwards into pure massive limestones, some of wliich would be valuable as marbles. The lower beds become more or less silicious and show embedded nodules of chert. These cherty beds afford transition to the Knox limestones, which are very cherty in the upper portions. The lower portions contain much shale with silicious limestones, and near the base is a curious limestone, some- what silicious, which is veined with white spar and contains great blotches of the same material. This is a notable bed, which is recognized in many places where it promptly affords a key to the puzzles. Its presence on New river and at several other localities in Pulaski county shows the rela- tions of the rocks on both sides of the Walker and Pulaski faults, and Stevenson.] ot) [March 18, proves the presence of Knox beds in that part o'f Pulaski county lying between the Altoona railroad and New river. A good section of this group should be obtained along the Valley pike in "Wythe county beyond Reed creek, beginning near Kent's Mills, where the series is well exposed almost to the fault of Draper mountain. Along the southern side of Wythe and Pulaski counties, the Knox beds, more or less dolomitic, carry important deposits of zinc and lead ores, some of which have been utilized. The mine of the "Wythe Lead and Zinc Company will be described in its own place. There the lead ore has been worked for more than a century, but the zinc ore had been neglected until the near approach of the Cripple Creek extension of the Norfolk and Western railroad led to its development and preservation. The zinc ores at the Bertha mine, also in Wythe county, yield a spelter of the finest quality. This strip of zinc and lead ores extends from Smyth county across Wythe and Pulaski, but developments thus far have been confined to Wythe county. The brown hematites of tlie Knox limestones in Pulaski and Wythe counties, along the New river and its tributary, Cripple creek, have been well described by Mr. A. S. McCreath,* who examined most of the open- ings and analyzed the ores, using samples collected by himself. The ore lies not far from the lead and zinc, and appears to be present in great quan- tity. Much of it is of excellent quality. Manganese oxide and barytes are reported as occurring at several local- ities, but no information was received respecting the quantity. The Cambrian. Here are placed the Lower Knox shales and the Potsdam. The former are probably equivalent to the Hj^dromica schists of Pennsylvania and the lower part of the Calciferous of New York ; the latter is the Potsdam of New York, vastly increased in thickness. The Knox shales are shown in Draper valley, within Wythe and Pulaski; they surround Lick mountain in Wythe and continue for some distance eastward along the anticlinal ; they are continuously exposed within a mile of the southern border of Wythe and Pulaski counties, and are brought up for a little way under an anticlinal lying south from the Wytheville synclinal. I'or the most part these shales are reddish, sometimes streaked with white, usually more or less greasy, often talcose-looking on the slipped surfaces. The rock is hard and is used for repairs of the "V^alley pike. An admirable exposure occurs on that pike for some distance east from the Cripple Creek railroad crossing, and one almost equally good is on the road crossing Lick mountain on the way from Wytheville to Brown Hill fur- nace. Streaks of limestone occur in the upper part, but they are wanting below. In the upper part are also some beds of yellow and blue shales, * The Mineral Wealth of Virginia tributary to the lines of the Norfolk and Western and Shenandoah Valley Railroad Companies. 1884. 1887.] ^' [Stevenson. but they are thin. These shales are hard enough to form bluffs ; where they have been long exposed to the weather, their surface becomes very dark and the dismal effect is increased by the abundant growth of ashen lichens, which are never absent from the older outcrops. The thickness of the group cannot be determined without careful study, as at all locali- ties crossed the beds are badly folded ; but it cannot be less than six hun- dred feet. The Potsdam forms the great mass of Lick mountain ; is the sandstone of Draper mountain ; and is found along the southern border of Wythe, Pulaski and Montgomery counties. The upper beds are alternations of sandstones and shales. Tlie sandstones are mostly white, vary from slightly conglomerate to exceedingly fine grain, almost like quartzite ; many layers are hard and on long exposure become beautifully polished. The lower beds shown in the deeply eroded gorges of Lick mountain and on the northerly side of Draper mountain, are sandy shales, mostly gray- ish and often so thickly bedded as to be shaly sandstones. The bottom of the group is found not far from the line of Grayson and Carroll counties, but that line was not reached by the writer. No measurement to deter- mine the thickness of the group was attempted, as the bottom is not exposed in either Draper or Lick mountain, but in Draper the thickness is not less than 2000 feet, the calculation .being based on the dip and a rough esti- mate of the horizontal distance through the mountain from the fault to the bottom of the Knox shales. The amount of rock exposed along the road traveled over Lick mountain is not so great, but the deeper ravines of that mountain should show an equally extensive section. No fossils were observed in the Knox or Potsdam shales, but the search for them was not diligent. Some layers of sandstone near the bottom of the Potsdam sandstone yield Scolithus linearis aljundantly on Lick moun- tain ; but neither that nor any other fossil was seen in the Potsdam of Draper mountain. Ores of manganese and iron are reported as occurring near the bottom of the Knox shales, but no effort has been made to develop these except in a small way on Lick mountain. IIL THE REGION NORTH FROM BIG WALKER'S MOUNTAIN, BLAND AND GILES COUNTIES. In descending Walker's mountain by the Wythe and Tazewell pike, one leaves the Medina at the summit and comes to a fossiliferous bed at barely one hundred feet vertically below the mountain crest. This is from six to eight feet thick and contains many typical Hudson fossils in great num- bers ; Bhynchonella increbescens, Orthis occidentalis (?), Avicula emacerata, Ambonychia radiata, Modiolopsis with fragments of Orthoceras were col- lected within a few moments. Other fossiliferous beds were seen lower down the slope, but no specimens were taken. These reddish shales with streaks of sandstone pass gradually into the yellowish shales of the Hud- son, which in turn pass into the dull reddish calcareous shales or shaly Stevenson.] CO [March 18, limestones of the Trenton. The cherts at the base of the Trenton or top of the Calciferous are reached at the first house. Thence exposures are rare until at the Sharon Springs some sandstones with indefinite dip are shown in the stream. These springs, which are the sources of the North Fork of Holston river, are very large and issue from very near the Salt- ville fault. The place was a popular summer resort in former times, but the construction of the railroad through the Great valley made it practi- cally inaccessible and the hotel has few visitors. The Saltville fault passes very near the yard at Sharon Springs, the ridge behind the hotel being sandy. The dip where the pike passes through this ridge is southward at fifty-eight degrees, and the silicious limestone of the Vespertine is shown at the nortlierly foot of the hill. The lower beds of the Vespertine have been eroded near the pike, but at a fourth of a mile eastward they form a low hill, in which a coal bed was mined at one time to supply local needs. The pits have fallen shut and most of them appear to have been little more than extensive strippings along the out- crop. The thickness varies greatly ; it is reported as eleven feet at one place. The coal is badly twisted, but the crushing and polishing are much less tiian at many other localities. Notwithstanding this crushing, the volatile matter is considerable and the coal cokes on the fire. The rocks enclosing the coal are regular and not much distorted except at one place, where the distortion may be due to a surface creep. The Tazewell pike continues northvv^ard, crossing Garden mountain, and, within a direct distance of four miles, entering Burk's garden, to which reference was made in the notes on Russell and Tazewell counties. This road was not followed beyond the abandoned coal-pits. The Rich Valley road is near the top of the Calciferous until six or seven miles beyond Seddon, where it crosses the Saltville fault ; but within a little way it returns to the Calciferous and remains in it. The Calcif- erous limestones and shales are apparently non-fossiliferous ; certainly fossils are rare, none having been seen, though the exposures were exam- ined for several miles. The dips vary from twenty to forty degrees, the more common rate being not far from thirty. Waddell's lead mine, aban- doned long ago, is a group of rude excavations in Calciferous at five or six miles east from Sharon Spiings. The road leading to Hunting Camp creek leaves Rich valley at nearly seven miles from the springs. The dips quickly steepen on that road, so that limestones exposed in the little stream-bottom near the first house are dipping southward at from fifty to sixty degrees. The Saltville fault is reached at barely half a mile, at top of an abrupt grade beyond the first house. The blossom of a thin coal bed, indicating a thickness of not more than ten inches, was seen at the top of the first hill, which may be the same with a thin bed digged in the bed of a run not far west from the road. The silicious limestone is exposed at R. Waddell's house and a coal bed is worked in a small way by ]\Ir. Harmon, very near the summit of the road, which is far from being the summit of Brushy mountain. The pit 1887.] ^^ [Stevenson. was not examined and the thickness of the bed, wliich is said to be between three and four feet, was not ascertained. The road descends rapidly on the northern side to a large branch of Hunting Camp creelv, wliich follows a long gorge through Brushy mountain. The upper conglomerate of the Chemung is shown soon after the stream has been reached and forms a ridge on each side of the road ; the exposed thickness is not far from forty feet. The layers of conglom- erate are distinct and one of them is ferruginous, with pebbles as large as a walnut. The gorge below this is exceedingly rugged, the shaly beds of the Chemung being held in cliffs by thick flags which are shown nicely in the stream so often crossed by the road. A second gray sandstone, with layers of conglomerate and closely resembling the former, is shown just above the mouth of the gorge. The more shaly beds at the base of the Chemung are shown as one approaches Hunting Camp creek, at Mr. Soutter's. There one sees, in looking back, that the tributary streams have cut Brushy mountain into parallel ridges, each with one of the harder Chemung sandstones for its crest. The lower shales of the Chemung with their hard flags form a low but very distinct ridge, which follows the foot of Brushy mountain and curves round the easterly end of the Garden anticlinal to form a similar ridge for a little distance between Round and Rich or Wolf Creek mountains. The Hamilton shales, which can be hardly separated from the Chemung dur- ing a hasty examination, continue to the northerly side of Hunting Camp, where the road first reaches it, though at a little way further down the stream cuts almost to their base. The Oriskany sandstone is exposed just north from the creek at barely a mile below Mr. Soutter's and thence its fragments are very numerous. The rock crosses the end of Round moun- tain as the Burk's Garden anticlinal dies away, and it is shown in the road at a short distance above the mouth of Hunting Camp creek. The most notable fossil is the stem of a criaoid of which individual joints are extremely common. Spirifera arrecta appears to be more abundant than any other of the ordinary forms. Evidently associated with the sandstone, but not seen in place, is a white chert, which contains a delicate Stroma- topora. Whether this represents the Lower Helderberg or not could not be determined. The road to Seddon leaves Hunting Camp creek at about two miles from its mouth and crosses Brushy mountain to Rich valley, at Seddon. The shales northward from the creek on this road are without doubt largely Hamilton, but beyond the creek southward the road quickly enters the low ridge of olive shales and flags, which has been referred to already as persistent along the foot of Brushy mountain for fully twelve miles. As the road ascends the mountain, it passes over olive flags with olive, gray, ash'en, blue and yellow shales, continuing to the summit of the road ; the southward dip being somewhat irregular, but rarely falling below twenty, or rising above forty degrees. These shales show no fossils aside from occasional impressions of cricoid joints and rude traces PROC. AMER. PHILOS. SOC. XXIV. 125. L. PRINTED APRIL 30, 1887. Stevenson. J "^ [March 18, of fucoids on the surfaces of the flags. Similar shales and flags continue for a little distance down the southerly side of the mountain, but the upper beds are soon reached and some of them are very fossiliferous. On one slab Bhynchonella orbicularis, (?) Grammysia sttbarcuata, 3fodiomorpha, Mytilarca and Edmondia were seen and the specimens were remarkably well preserved. The gray sandstones of the group are not exposed along the road, but their fragments are very abundant and the rocks themselves form the summits of the subordinate ridges. The Kimberling anticlinal is crossed at less than half way down the mountain and brings up again at least one of the sandstones. The passage to Vespertine is not easily made out. A mass of red sandstone occurs in a narrow gorge, say half a mile from Seddou, which probably marks the bottom of the Vespertine. Coal belonging to that group has been mined in a small way at half a mile west from Seddon and at about the same distance north-east from that village. A mine has been opened for domestic use at about three miles further east ; but none of these pits was visited. The topography is reversed on the road crossing Brushy mountain, the long gorge being on the southerly side. The road in Rich valley lies in Calciferous for somewhat more than sis miles from Seddon or to a little beyond Point Pleasant. The chert ridge is south from the road and attains to considerable height in its eastern extension. The road lies south from the Saltville fault to Point Pleasant, but almost directly beyond that place it turns northward and thence to the road crossing the mountain to Kimberling creek it lies north from the fault. The dips in the limestone seldom exceed thirty degrees, except near the fault, where they become fifty-five and sometimes even more. Expo- sures are very indefinite along the road to Kimberling creek, as it ascends the slope of Brushy mountain. No coal blossom was seen and no coal is digged anywhere near the road. Fragments of the Chemung upper con- glomerate are very numerous at the first summit of the road and the rock forms the crest of the first main ridge. Between this and the second or main summit of the road, fossils maybe obtained in considerable quantity, Rhynchonella, Chonetes, Orammysia and Qoniopliora all well preserved, having been obtained from a single block. Ambocoelia occurs in vast numbers, its casts forming the mass of several tliin beds. From this sum- mit to Kimberling creek, the road is in the shales and flags which are exposed almost constantly thence to the mouth of No-Business creek. The dip is steadily southward, but becomes comparatively gentle along the creek, being barely ten degrees at the mouth of No-Business. There Kimberling changes its course to south-east and evidently flows through Devonian to where it crosses the Saltville fault at two or three miles east from Mechanicsburg. The stream was followed only to witliin about four miles of the fault so that the limits of groups as given on the map are only approximate. Dismal and No-Business creeks, tributaries of Kimberling, take their rise respectively in Sugar Run and Pearis mountains, double outcrops of Medina with Clinton between the outcrops : but the streams 1887.1 "J- ' [Stevenson. enter Kimberling in Devonian, wliicli is the surface group in nearly all of the broad space between Brushy mountain at the south and Wolf Creek mountain at the north, the distribution being due to the disap- pearance of the Burk's Garden anticlinal and to the growth of the Kim- berling anticlinal. The portion of the area lying north from Kimberling is almost uninhabited and is known as the "Wilderness." Exposures are very indefinite along the Wilderness road for some dis- tance from Kimberling creek on the way to Rocky gap ; but near Mr. Benton's house, at, say, two miles from the creek, tlie rocks are dipping northward at nearly fifty degrees, and the rate increases at a little distance further, as is well shown by exposures in the stream. The dip again becomes southward at somewhat more than a mile from Benton's house and the Chemung rocks are soon shown with almost ver- tical dip forming an irregular broken ridge. No exposures aside from those of a few dark shales occur in the interval to the next ridge, a space which should be occupied by Hamilton. A sandstone ridge, evidently Oriskany, is cut by the road at somewhat more than a mile and a half from the Rocky gap by which Wolf creek passes through Wolf Creek mountain, the same with that known in Tazewell county as Rich mountain. This ridge is cut by the creek at, say, three-fourths of a mile from the forks of road at head of the gap. No fossils were observed in the sandstone. Some white chert which may represent the Lower Helderberg was ob- served here. The Clinton is quickly reached with its dark red sandstone ; it makes a well-marked ridge and terrace along the southerly foot of Wolf Creek mountain. Fossil ore occurs very abundantly, but the fragments seen along the foot of the mountain are very silicious. Medina is shown in the stream-bed at the very head of the gap, whence it rises rapidly to crest of the mountain with a dip of twenty-five to twenty- seven degrees. The immediately underlying red beds are more silicious than at most of the lo- calities visited, and they are exposed to a thickness of about 250 feet. Ex- posures are very indefinite beyond this until the Trenton is reached mid- way in the gap. The Calciferous beds next come up and at the mouth of the gap they are dipping southward at thirty-five degrees. These beds prevail to the cross-roads at J. D. Honaker's store. Wolf creek bends northward immediately below Honaker's store and soon crosses the Wenonah fault, which brings Calciferous against Clin- ton, the dip of the latter being eighty degrees. The Medina caught in this double fault forms the Valley ridge, which is persistent thence to the New river. The creek passes through this ridge at say a mile and a halt below Honaker's and affords a fine exposure of Medina on the easterly wall of the gap. The Calciferous limestones are reached immediately behind the ridge and within one-fourth of a mile are faulted against the Medina of Buckhorn mountain, a low ridge following the southerly foot of East River mountain. The road crosses this fault to the IVIedina, but returns to the limestone on the hill opposite Mr. Carpenter's house about Stevenson.] "^ [March 18, three miles from J. D. Honaker's store. Thence to New river the road is in the limestone between the two faults. The creek approaches the Buck- horn fault very closely near the line of Giles county, but the Wenonah fault, whose course is marked by the Valley ridge, is touched nowhere by Wolf creek below the gap near Honaker's. The dips in limestones be- tween the two faults vary greatly, being from fifteen to forty degrees along the creek ; but the rate diminishes toward New river, where it rarely exceeds twenty degrees. Though underlaid by limestones and cal- careous sandstones, much of this Wolf Creek valley is very poor. Great fragments of Medina are numerous and the disintegrated sandstone has contributed most largely toward formation of the detrital covering. The valley between Buckhorn and East River mountains is reported to be "freestone." No examination of its structure was made, but there appears to be a synclinal here, in which case the surface rocks would be Silurian shales. The valley is contracted near the mouth of Wolf creek and the locality is known as the "Narrows." The crest of Wolf Ci'eek mountain is carried northward in a bold knob which overlaps the Valley ridge. Thence it recedes southward, limiting the broad deep valley of Mill creek, to return northward and fdrm the bold knob of Pearis mountain. The point of this mountain is at about two miles from Pearisburg and there the Medina outcrop curves southward under the influence of the Kimberling anticlinal. The Valley ridge becomes indistinct where the fault is crossed by the pike near Wenonah station. Thence to Pearisburg the road lies in Calciferous and Trenton limestones. The S5rnclinal north from the Kim- berling anticlinal is crossed by the Dublin pike at the southerly end of Pearisburg and in this is the "Angel's Rest" or terminal peak of Pearis mountain. The outcrop of Medina climbs the anticlinal as the fold de- clines, crosses it at the head of Sugar run and then moves eastward along the southerly side of the anticlinal. It soon recedes toward the west as it ascends the weakening anticlinal of Sinking creek and finally disappears against the Saltville fault.* That fault is crossed by the Dublin and Pearisburg pike at a very little way north from Poplar hill, where the Trenton and Calciferous are in contact and the road passes into the Rich valley between Big Walker's mountain and the Saltville fault. A road, leaving the pike north from Poplar hill and leading to New river at Scott's ferry, crosses the Saltville fault at four miles from the pike or at a little more than one mile by Walker's creek above Stafford sville. Erosion here, as on the pike, has cut away all rocks higher than Trenton limestone from the north side of the fault, but, within a short distance, the Medina appears again and forms Buckeye ridge, the northern boundary of Rich valley to and beyond New river. The dying away of the Walker's Creek anticlinal permits the Walker's Mountain outcrop of Medina to advance northward so that the valley is narrow near New river. * This outcrop was not followed to the Saltville fault and the statement given in the text is based on the topography. 1887.] "'^ [Stevenson. The many railroad cuts along New river from this gap northward to Big Stony creek exhibit the structure very well. Only Calciferous is shown under the Kimberling and Sinking creek anticlinals until the Wenonah fault is reached near the mouth of Big Stony creek, where one sees Medina. Thence to the foot of Buckhorn or Little mountain the limestone is exposed in cuts and loss frequently in natural outcrops. The surface of the area between Pearls and Sugar Run mountains on the westerly side, and the Salt Pond mountains on the easterly side of New river shows traces of erosion planes. The underlying rocks belong to the Calciferous, Trenton and Hudson, but the detrital ccatis very thick and for long distances completely conceals the bedded rocks. The Buckhorn fault is continuous eastward from New river certainly for twelve miles and the limestones of the Calciferous are exposed fre- quently along Big Stony creek. The fault runs along the face of Buck- horn or Little mountain, but what l)ecomes of it or of the limestone valley iust south from it was not ascertained as the creek was followed only for three miles from the river, but ihe valley appears to be continuous to the county line. Big Stony creek approaches very closely to the "W^enonali fault at barely a mile from the river, where the limestone is turned up suddenly at forty degrees northward and Medina is shown in the hill above. A road leading to Little Stony creek leaves this stream at rather more than two miles and a half from the river. The Medina of the Valley ridge is reached before one comes to the first house, being shown in place at a little way from the road. The summit of the ridge is about GOO feet above New river at Snidow's lower ferry and there the Medina is reached a second lime. The rock is not shown in place, but the surface is covered with fragments of the sandstone which could hardly have come down from Butte mountain. The limestones are reached again as the road descends to a little stream and they are still dipping southward. The Trenton shales and shaly limestones are shown on the next ridge, but the Hudson beds are shown only further up the ridge eastward from the road. The summit of the road, at approximately 400 feet above the river at Snidow's lower ferry, is covered with debris of Medina and this ridge is merely the termination of Butte mountain. The Pearisburg syn- clinal passes at somewhat more than a mile from Little Stony creek, and the northward dip is well shown on the road as it descends to the creek. The Trenton limestones form a bold ridge on the southerly side of the creek, the southerly wall of a deep gorge which has Butte mountain for its northerly wall. Medina forms the double crest of Butte or Big mountain. The northerly outcrop encroaches on the narrow strip of Cambro-Silurian between the mountain and the Valley ridge so that the two lines of Medina appear to overlap. The area of the lower rocks is certainly so narrow that it cannot be represented on the map. The road to the Mountain lake leaves the pike at Doe creek, which it follows to very near the lake. The cherts of the Calciferous are exposed 04- Stevenson.] ^^ [March 18, at the pike and the axis of the Kimberling anticlinal must pass near the fork of the road. The Lake road winds up the mountain side and reaches the Hudson beds within two miles of the lake. The Pavilion Knob, just west from the lake, shows the red shales with Rhynchonella and AmhonycMa half way up, while at the very top is a large Lingula in vast numbers associated with a Modiolopsis. Medina caps several knobs on the ridge between Doe and Little Stony creeks. The outcrops of that rock meet on the summit of the Kimberling fold at a considerable distance east from the lake and thence to the eastern edge of Giles county Big and Salt Pond mountains are covered by dense forest, through which no road passes. The Mountain lake or Salt pond is at somewhat more than 4000 feet above tide and is three-fourths of a mile long by one-half mile wide, the measurements being extreme in each case. It occupies a great sinkhole, which, within fifty years contained only a small pond of water at the bottom of the depression, by which a farmer salted his cattle. In some way, the outlet of the pool became choked, and water from the adjacent springs accumulated until it overflowed the rim and discharged itself into Little Stony creek. The subterranean outlet may be opened again and the pond drained. The spot is very attractive, and at one time it was a popular resort. The road to Newport winds along the side of Salt Pond mountain, descending rapidly after it passes the point of the mountain, which is in the synclinal between Kimberling and Sinking Creek anticlinals. The Trenton shales are reached at about three miles from the Lake hotel and are thrown into numerous and complex folds, many of which are broken and slightly faulted along the axial plane. These occupy the synclinal and exhibit conditions the same with those observed in these shales in the Pearisburg synclinal on the point of Butte mountain. The massive beds of the Trenton are reached quickly after the road begins direct descent to Sinking creek, but exposures soon become rare, as the surface is thickly covered by debris, derived largely from Medina, of which huge fragments are numerous. The Calciferous cherts are shown occasionallj', but not in place. The Sinking Creek anticlinal is crossed at not more than two-thirds of a mile north from that creek, and the massive limestones of the Trenton are shown at the stream with southward dip. The pike is reached at a little way beyond the creek, and there the Trenton shaly limestones are shown much distorted and describing many complicated folds ; the dip on each side being often eighty degrees. The thicker limestones are brought up several times. The road crosses the Saltville fault at a little more than half a mile north from Newport, the Trenton shales being brought into contact with the lower cherts of the Calciferous. The fault passes along Buckeye mountain, which, where crossed by the pike, has suifered much from erosion ; but at a little distance on each side the Medina is present and the mountain is conspicuous. The Sinking Creek anticlinal diminishes eastward and the Medina outcrops unite before reaching the county line. 1887.] *^^ [Stevenson. Rich valley widens between Xew river and Newport. The dips in its limestones are from fifty to sixty degrees. The massive beds of the Tren- ton are shown on Gap or Big Walker's mountain with this dip, and Medina at the summit shows a dip of sixty degrees. Exposures are very good on the northerly side of this mountain. IV. THE COUNTRY SOUTH FROM WALKER'S MOUNTAIN, EM- BRACING PORTIONS OF WYTHE, PULASKI AND MONT- GOMERY COUNTIES. By far the greater part of Wythe county south from the Norfolk and Western railroad shows only rocks belonging to the Knox group, but the Potsdam is brought up along the southern border of the county, as well as at a little way from the railroad, in a bold east and west ridge, known as Lick mountain. In going southward from Wytheville, one finds the Knox limestones so much twisted as to suggest that the Draper mountain fault has not wholly disappeared. The Knox shales are shown within two miles from the railroad, where the road enters Lick mountain and the Pots- dam beds at not many rods further. The sandstones of this great group form the hog-back ridges, of which the mountain is made up, while the shales are exposed in the deep ravines. 'The sandstones are passed at about eight miles from New river, where one comes again to the Knox shales, which are badly distorted. On the road leading to the Wythe lead and zinc mine, which is reached at about two miles from Cripple creek, the rocks are concealed for long distances by the thick cover of terrace debris ; but the Knox limestones are well shown in the river blufls, at the Wythe lead and zinc mine, both above and below Thorn's ferry, where the New river cuts a fine anti- clinal. The Wythe lead and zinc company have their mine at Austinville, in Wythe county, nearly seventeen miles from Wytheville, or twelve miles from Max Meadows station. The ore was discovered and first utilized not far from 130 years ago, but systematic mining has been prosecuted for barely fifty years. The reduction works have a capacity of between 600 and 700 tons per annum, and are of interest, as they were practically the only lead works within the limits of the confederacy and yielded nearly all of the lead employed in the manufacture of bullets for use of the Confeder- ate soldiers. The lead and zinc ores occur in an enormous impregnation deposit and are extracted both by open cut and by deep mining. The conditions in the surface workings are approximately as follows : 1. Gray limestone 25' The upper part shows a network of galena ; some excellent blende almost free from galena is found midway ; while lower down both galena and blende occur abundantly. The lower half of the rock, which had been digged extensively, is said to contain a large amount of both blende and galena ; but it was concealed by a slide at the time of examination. Stevenson.] Jt) [March 18, 2. Gray sandy limestone 10' This appears to be barren. 3. Ore 8' This consists of carbonate and silicate of zinc associated with much galena. The calcareous matter has been leached out and the ore is in irregular honeycomb masses. 4. Limestone, evidently barren 9' • 5. Ore 8' The conditions are the same as those in No. 3. 6. Limestone, gray 25' This contains a very large amount of blende and galena, but the ore is not sufficiently concentrated to make working profit- able. 7. Ore 2 to 10' The conditions in this are the same as in Nos. 3 and 5. The deposit shows more irregularity than was observed in the others. 8. Limestone, apparently barren 10' to 12' 9. Ore 6' to 10' Here too the calcareous matter has been removed and the ore, which consists of zinc silicate and carbonate, with only a trace of galena, is cavernous. 10. Limestone, barren, seen 5' No further exposures occur. The upper edges of the limestone in this extensive stripping are rounded as though they had been exposed to long erosion, and the whole was covered with a tough reddish clay, fifteen to thirty feet thick, overlaid by slidden material, ten to twenty feet thick. For the most part the clay is barren, but sometimes it yields fragments ot galena and altered zinc ores ; and at a cutting just beyond No. 10 it has yielded a very considerable quantity of earthy carbonate of lead. These silico-carbonate ores are merely superficial, for at less than 100 feet from the surface in No. 9 blende occurs to the almost complete exclusion of calamine and smithsonite. Though commonly spoken of as "leads," these deposits have no fea- tures entitling them to that name. The characteristics are well shown in surface workings made on this property by J. S. Noble in 1866, when he mined the zinc ore for shipment to New Jersey. These pits, at say half a mile from the tipple of the present surface workings, are on Bald hill, where erosion has removed the superficial material so as to expose the limestone over many acres. As the lease under which the work was done was short and as lump ore alone was to be removed, the deposit was worked only where richest and most distinctly marked ; when it became indefi- nite the pit was abandoned and a new opening was made elsewhere. The whole area is pitted and the openings vary greatly in shape. Clearly no 1887.] y* [Stevenson. Systematic mining is possible in deposits such as this, and the only availa- ble method is follow ore, wherever found, until it ends. The separation of the lead and zinc ores is effected by jigging. The ore, after crushing and grinding, passes to the jigs, which are in sets of four. The galena is almost wholly removed in the first, while the ores of zinc are separated by the remaining three. The separation is almost com- plete and the amount of escaped ore passing off in the tailings is insig- nificant. Much of the lead produced here is manufactured into shot of decidedly excellent quality, and an air-shaft, 263 feet deep, is utilized as the shot tower. Along the road leading from Thorn's ferry to the Valley pike, exposures are few until Mr. Raper's house has been reached, but thence to the pike exposures are good. The Knox limestone is shown in the road near Mr. Raper's house and at a little way further the shales are at the surface. But a slight fault exists here, for the limestone re-appears within a few rods and continues until a short distance beyond the road leading to Walton's furnace. Thence to the pike the road lies in the shales and the Potsdam of Lick mountain nowhere reaches it. The beds seem to be thrown into two anticlinals, of which the more northerly is crossed near the last fork in the road, less than two miles from the pike, which is reached at barely seven miles from Wytheville. Knox limestones, dipping west of north at sixty-five to sixty-seven degrees, are well exposed in Wytheville along the street leading Irom the railroad station to the court-house ; but exposures are very poor for some distance northward from the borough on the Wythe and Tazewell pike. The dip is soon changed on that side and the first good exposures show the south of east dip practically the same as the opposite dip on the other side of this Wytheville trough. The ridge on which the borough of Wythe- ville stands marks the course of the synclinal, which is cut off by the Max Meadows fault at a little way further east. The anticlinal north from this, in which the Max Meadows fault may originate, has been crossed before one comes to the blacksmith's shop two miles and a half from the court- house in Wytheville, for there the dip is northward at from twenty-five to thirty degrees ; but the place of the axis cannot be determined easily as the surface is covered with a thick coat of sands and clays. The dip is changed .again at somewhat more than two miles and a half from Stony Fork of Reed creek, the southerly direction being very marked at the S-curve in the road, while at Mr. Brown's house it is fifty-five degrees almost east of south. This direction of dip continues to the little valley in front of Stony Fork M. E. Church, where the Walker Mountain fault is crossed and one comes to the Umbral shales. The Knox limestone is well shown in the low hill, while shales are seen at its northerly foot dipping toward the fault at from thirty to thirty-five degrees. The shales are exposed occasionally at the roadside, and one comes to the silicious limestone at the Vespertine ridge, which forms the foothill of Little Walker mountain. The coal-bearing group begins below this limestone and its PBGC. AMER. PHILOS. SOC. XXTV 125. M. PRINTED MAY 3, 1887. Stevenson.] "o [March 18, red or brownish-red sandstones are shown for some distance southward from the ford. Col. J. T. Boyd of Wy theville has opened several of the coal beds along- side of the stream as well as in a hollow coming down by Mr. Davidson's house. The numerous openings on the south side of the creek show fairly well the relations of the lower beds, the following section having been obtained : 1. Coal bed, V, said to be 1' 6" to 3' 2. Interval, said to contain Coal bed, IV, 2' 67' 3. Coal bed III, said to be 1' 1" 4. Sandstone and shale 13' 5. Coal bed II, said to be 6' or more to 2' 6" ■6. Sandstone 17' 7. Coal bed 1 0' 10" 8. Sandstone, seen about 20' Mr. C. R. Boyd, who has reported on this property, says that the inter- val, No. 6, becomes thirty feet at only a few rods from the locality visited. Coal beds II and III have been opened in a hollow above Mr. Davidson's house, where both are badly crushed, the lower much more than the upper. The roof shales have been crushed as badly as the coal at most of the pits, but at one under the road and alongside of the creek a fragment of Lepidodendron was seen, altogether without distortion ; at all other points, however, the crushing and consequent distortion have practically destroyed all details of structure. The underclays are full ot leaves or appendages belonging either to Lepidodendron or to Stigmaria. The coal bed, II, has been opened at several places along its outcrop east from the creek, where it shows material variations in thickness and structure, due evidently to the pressure which the bed has undergone. The thickness at one opening appears to be more than four feet, but the structure could not be made out. A new cut showed 1. Black shale and coal streaks 1' 6" 2. Clay 1' 0" 3. Coal 2' 6" Here there is apparently no distortion, but the crushing is no less severe than at an older pit where the bed has been twisted beyond recognition. The coal occurs in thin laminae, easily separable and beautifully polished. The "Quarry rock," the lowest bed of the Vespertine, which comes to the creek at the coal pits, is a gray, sometimes slightly conglomerate sand- stone. The Chemung is not well shown in the gap through Little Walker mountain. The relation of Devonian to Upper Silurian is not altogether clear, as the Oriskany was not recognized in the "Poor Valley." Black shales, dipping northwardly, were seen nearly opposite Mr. Hedrick's house, which seem to be continuous thence to the final crossing of the stream, where they are associated with drab and yellow shales which con- tain fossil ore and are of Clinton age. From that place, the road winds for 1887.] *^" [Stevenson. three or four miles vip the side o' Big Walker mountain and for certainly- half the distance is on Clinton which is thrown into many narrow folds. Where the Medina is first reached, the dips vary from fifteen to twenty- five degrees, but the rate increases, until at the summit the lower beds with ArtJirophycus Jiarlani dip soulh-eastw ardly at forty degrees. Another form, like a ScoUtJius, penetrating a layer about ten inches thick, is seen at the summit. It is single at each surface of the layer, but forms a loop in the body of the rock. The Vespertine beds form a foothill to Little Walker mountain and are faulted against the Lower Silurian rocks in Crockett's Cove of Wythe county as they are on Stony Fork of Reed Creek. But the Max Meadows fuult crosses the strike and the eastern side of Wythe county shows a much longer continuous section than is found in the western part. On the southerly side of Crockett's cove the Trenton and Hudson beds pass upward into the short but bold Medina ridge known as Cove mountain, which is a notable feature of the scenery. Clinton forms the southerly flank of the mountain as well as the northerly side of the valley between Cove mountain and Max Meadows or Tract mountain, which lies north from the railroad between Max Meadows and Pulaski. The southerly side of the valley is occupied by Devonian shales passing upward into hard sandstones of the Chemung, which make the body of the mountain. In following the Norfolk and Western railroad from Wytheville station eastward, one finds the north-westward dip continuous until the Knox shales are reached at about three and a half miles from Wytheville. Beyond that, exposures become few, but the road follows closely the line between the limestone and the shales until the Max Meadows fliult has been reached beyond Max Meadows. Exposures are good and almost continuous between Max Meadows and Pulaski. Some dark shales and impure limestones are exposed immediately beyond the former station and red shales are shown at and beyond the first small bridge. These are succeeded in the first cut by the dark lime- stone with veins and pockets of white spar, which lies at the base or nearly so of the Knox limestone. Owing to the direction of the railroad, this limestone is exposed until nearly two miles from Max Meadows. In a deep cut beginning there, the limestone has been replaced by a conglom- erate, which may be of recent origin. It is not less than forty feet thick, has no definite bedding and is variable in composition, some parts break- ing down readily on exposure, while others retain their shape and disin- tegrate very slowly. This may mark the course of an extinct stream. The next cut, beginning at two and a half miles from Max Meadows, shows first a gray sandstone, quartzite-like in fineness of grain, which is succeeded by irregularly bedded reddish shales with thin streaks of sand- stone, the dip being south eastward at about fifteen degrees. The shales in the next cut are very red and somewhat fissile. These continue to Clark's Summit cut, which begins at somewhat more than four and a half miles from Max Meadows, where they are succeeded by reddish sandstone Stevenson.] -*-^'J [March 18, and shales containing a thin coal bed. These have been thrown into petty folds and the coal bed has been the chiet sufferer. It has been squeezed beyond recognition as a bed and the coal is laminated ; but the lamination, unlike slatj' cleavage, is rudely parallel to the plane of bedding. The rock exposure ends abruptly midway in this cut and thence to the end, fully one-eighth of a mile, the material is a loose incoherent mass of clay and sand, loaded with fragments of sandstone, chert and a little lime- stone, all of the fragments being angular. This accumulation bears much resemblance to those containing "wash ores" in Bedford county of Penn- sylvania. The limestone at the top of the Vespertine is shown in this cut very near the beginning of the rubbish. The next cut shows the Vespertine rocks with a thin coal bed and with gentle dip. Some prospecting pits were sunk on the Clark property in search of coal, and, according to the report made to the writer, coal of fairly good quality was found in quantity to repay working ; but no at- tempt to utilize the deposit has been made. The coal in the cut is too thin to be of any value, but the Hon. J. S. Draper states that beds of worka- ble thickness occur on his property at a little way south. It is sufficiently clear that the Max Meadows fault is crossed at not far from three and a half miles from Max Meadows, and that the red shales in the cut west from Clark's summit belong to the Lower Carboniferous. Vespertine sandstones remain in sight to the Bertha Zinc Works, just west from Pulaski. Near the 86th milepost, or somewhat more than six miles east from Max Meadows, the blue sandstone is reached. This hand- some stone has been quarried for building purposes ; it has been used largely in railway masonry, and is the stone of which the IVJaple Shade Inn at Pulaski has been built. The rock is blue, fine-grained, cross-bedded and breaks with a conchoidal fracture. Where first seen it is exposed to a thickness of about twenty -five feet and contains many rounded balls of red clay or red shale scattered throughout the mass of the rock. The lower layer is less coarse but contains small pebbles of quartz and sand- stone. No fossils were observed at any of the exposures. This rock is shown along the railroad and Peak creek, forming bluffs alongside of the creek, and being quarried at several places on the rail- way. The thickness is not less than forty feet. Underlying it are shales and sandstones, the shales drab, gray to red, while the sandstone very closely resembles the more massive beds above. Some fucoids were seen in the red shales, but no other forms were observed. The synclinal between Peak hills and Draper's mountain is crossed by the railroad at the tunnel near the second bridge over Peak creek, where the north-westward dip is twelve degrees. The sandstones of the group form a line of hills south from the railroad which are distinct from near Clark's summit to certainly two miles beyond Pulaski. The railroad runs on the easterly side of the synclinal to the Zinc Works. Between those works and the station passes the Pulaski fault, which brings the Vesper- tine into contact with almost the lowest bed of the Knox limestones. 1887.] iUl [Stevenson. Returning to "Wytlieville and taking the macadamized road leading thence to Newbern, one rides on the lower limestones of the Knox group until he crosses Reed creek, where the Knox shales are shown, still dip- ping sharply toward the west-north-west. The first good exposure beyond the creek is at the roadside near Kent's mill, where the limestones are shown with vertical dip, so that the axis of the anticlinal must pass at but a little way from the creek. The dip gradually decreases and within half a mile the massive limestones are dipping at from twenty to twenty-five degrees almost south-east. These limestones belong to the upper part of the Knox. Haifa mile further east, there being no exposures in the interval, Knox red shales were seen with almost vertical eastward dip. An exposure of sandy limestone, also with nearly vertical dip, was seen on the northerly side of the road at a little way further east, but thence the exposures are poor for several miles. The dip is reversed again near the Max Meadows road. Where the road leaves Reed creek, at nine or ten miles from Wythe- ville, there is a close anticlinal whose formation was connected with severe disturbance, for the rocks are much crushed and there seem to be some petty faultings. The road turning southward soon rises to near the sum- mit of the Lick Mountain anticlinal and follows it for a number of miles. The rock exposed for a long distance is the same limestone with veins and pockets of wJiite spar, which is so well shown in the railroad cuts east from Max Meadows. It is associated with yellowish shales which are especially well shown in the cuts beyond the Pulaski road. The chert ridge is double in the synclinal between the Lick Mountain anticlinal and Draper's mountain, and it forms an imposing knob near Reed creek, while one side of it forms a low persistent ridge between the pike and Draper's valley, terminating in a double knob at the eastern end of the mountain. Tliis ridge is notched by many little streams which rise in the valley and unite to form larger streams only after passing through the ridge. The Pulaski road leaves the pike at about twenty miles from Wythe- ville and crosses Draper's mountain. As it passes through the ridge of Draper's valley it shows the Knox limestones with easterly dip. The limestones end at a little way east from Mr. J. S. Draper's house, which is on the Knox shales. There the road begins to ascend the mountain and within a short distance sandy shales or shaly sandstone of the Potsdam is imperfectly exposed at the roadside. The next exposure, beginning at somewhat more than half a mile from Mr. Draper's house, is continuous to beyond the summit. This shows Potsdam sandstone dipping south- eastward at from thirty-five to fifty-five degrees, the average being not far from forty-five degrees. No fossils were observed in this sandstone, but the rock bears close resemblance to the Potsdam of Lick mountain as much in the intercalated brown or reddish-brown shaly beds as in the sandstone itself. There is nothing on either side of the mountain to answer to Hud- Stevenson.] IVZi [March 18, son or Clinton, but on the northerly side is a mass of shale like that form- ing the lower part of the Potsdam on Lick mountain. These underlying shales are well shown on the northerly side of Draper's mountain, where, for a few feet directly under the sandstone they are almost black ; but for the most part they are grayish, sandy, and in rather thick layers, so that they might almost be termed shaly sand- stones. Their south-easterly dip is as abrupt as that of the sandstone on the other side of the summit. The Draper Mountain fault passes about one-third of a mile west north- west from the crest of the mountain, and on this road brings the lower beds of the Potsdam into contact with the lower Chemung shales. The Chemung sandstones form a bold ridge beyond the old Pepper road, in which the brownish beds contain many fossils. The Chemung conglom- erate was not seen in place as the foliage was very dense, but its frag- ments are numerous. Vespertine beds form the next, a low ridge in which traces of coal have been observed and the bluish sandstones have been quarried. Thence for a little way there are no exposures, but in the bank behind the Maple Shade Inn the veined limestone of the Knox group is quarried, while just beyond Peak creek, immediately north from the railroad station in Pulaski, limestone belonging to the same group is exposed. These limestones are shown on the country road to the Robin- son tract, a distance of about six miles, and that beautiful tract must also be underlaid^ by the Lower Silurian limestone; but no examination to ascertain this was made. The limit between the shales and shaly sandstones of Devonian and Carboniferous at the west and Lower Silurian at the east was not followed out in detail, but it passes almost midway between the Altoona coal road and the county road in Pulaski ; it is a little way west from the Poplar Hill church, four or five miles from Pulaski. Beyond that northward, it evidently lies east from the Altoona railroad. The Altoona coal mines are in Pulaski county, at eleven miles by rail from Pulaski, though the actual distance is much less. The bed now mined is the second of the Vespertine beds, which varies in thickness from four to twenty-two feet, in the latter case including not a little shale. The pressure has crushed the coal to such an extent as to destroy in great measure its marketable value, but a large quantity is mined each year for use at the Salt works in Smyth county. At one time the third bed, said to be four feet thick, was mined here, but work on it has been discontinued, only a small quantity being taken out to run the locomotives on the coal road. The coal from this bed is far superior to that from the other. A road follows the bottom of Peak creek for nearly two miles below Pulaski, and then leaves the creek to cross the easterly point of Draper's mountain to the Valley pike, which it reaches at somewhat more than a mile and a half southward from Peak creek. The Vespertine ridge is cut off by the Pulaski fault before this road reaches the line, but the Devonian ridge continues beyond the road. The Draper Mountain fault is greatly 1887.] iUd [Stevenson, diminished in strength and the Potsdam sandstone makes little showing along this road. That rock evidently extends to near Peak creek and the limestone on the north side of the Pulaski fault must be in contact with it near the creek. Where the road reaches the pike, Knox shales are shown at the roadside with almost vertical dip. For the most part they are red, weathering dark brown and covered with lichens. "With these are some yellow and blue shales, and streaks of impure limestone. The shales continue along the pike to beyond Peak creek^ where one crosses the Draper mountain fault and comes again to the Knox limestones. An anticlinal was observed in Newbern, the county seat of Pulaski county. Thence to half a mile north from Dublin the limestones are dipping northwardly. But a little more than half a mile north from Dublin, exposures practi- cally cease and thence almost to Back creek very little is shown. The whole space is an old erosion plane and the bedded rocks are con- cealed under a deep cover of debris. The few imperfect exposures show only shales, which are dipping southwardly. These belong to the lower part of the Knox limestone and are the same with those exposed on the valley pike, east from the Pulaski road. Limestones are reached near Back creek and continue to perhaps half a mile or more north from that stream. The beds appear to be wholly without fossils, but their relations are clear enough and they belong to the lower part of the Knox limestone. The lowest bed js the dark limestone carrying veins and geodes of white spar, which is exposed for a long distance on the Valley pike, east from Reed creek. After crossing Back creek, the road begins to ascend Cloyd's or Little "Walker mountain and exposures are good. A great thickness of red shales comes immediately behind the geodal limestone and some of the upper beds are very like those of the Knox shale ; but shales of very different character are soon reached, which belong to the Lower Carbonif- erous, to the Umbral period. The Vespertine or coal-bearing division is reached at a short distance below the Jennell place, where one of the beds has been mined to some extent. The blossoms of four beds are shown in the roadside, above the Jennell house, within a vertical distance of about 115 feet. The upper beds are not more than three or four inches thick, but the second is almost nine feet from rock to rock. It is said to contain one foot of good coal at the bottom, while the rest of the interval is occu- pied by alternating thin layers of coal and shale. The lowest bed is from two feet to two feet six inches thick, and is said to yield very good coal. This is said to be the bed worked by Mr. J. H. Tyler, two miles east from this road. That mine was not visited. The interval between the two beds at the roadside is about fifteen feet and is filled mostly with sandstone. The lowest bed of the Vespertine is a gray sandstone, well-shown at the roadside. The passage to the Chemung is imperceptible through con- cretionary sandstone and shale, undoubted Chemung being reached in a fossiliferous sandstone containing Chonetes and other forms which are not Stevenson.] iU* [March 18, recognizable on the weathered surface. Concretionary sandstones con- tinue below this and, at say 300 feet lower in the series, the upper con- glomerate of the Chemung is shown, with not a few of its layers contain- ing flattened pebbles. The concretionary structure gradually disappears iQelow the conglomerate and many of the beds on the northerly side of Cloyd's mountain are fossiliferous. The conglomerate forms the crest of the mountain for nearly the whole length. The variegated flags and shale in the lower part of the Chemung are reached quickly on the northerly side of the mountain as the road descends- to the valley of Little Walker creek. Exposures are fairly good in the valley and in the gap through Big Walker mountain, but Oriskany was not recognized, so that, if present, it must be very thin. Medina forms the great part of Big Walker moun- tain and is fairly well exposed in the gap made by Little Walker creek. The Medina is well shown in the gap made through Big Walker moun- tain by New river, where it appears to be in all not far from 375 feet thick. Good exposures occur here between the mountains, but, if present, the Oriskany and Lower Helderberg are so thin that they escaped obser- vation. The Chemung beds are sufficiently well shown to make the con- struction of a complete section by no means difficult to one doing syste- matic work ; but no section was attempted by the writer, who began his examination near the top of the group. The "point " of Cloyd's mountain in New River gap is at a little more than eight miles from New River station on the main line. There the Chemung conglomerate, which forms the backbone of the mountain, comes down to the river and is exposed in a railroad cut. Behind it for about 130 yai'ds — beyond which no examination was made — fragments of the bluish-red sandstones of the Chemung are plentiful in the debris which covers the mountain side. TMany of these fragments are fossiliferous and the locality will prove to be a good one for the collector. The sandstones are very hard and the fragments are used in ballasting the track from this place almost to New River station. The upper conglomerate of the Chemung, as shown in this New River gap through Cloyd's mountain, is not far from thirty feet thick. Its upper part is well exposed, is about fifteen feet thick, very hard and coarse, with pebbles often as large as a hen's egg, mostly of quartz and frequeutlj^ flat. In some of the layers the longer axis of the pebbles is vertical to the plane of bedding. The lower part is less hard, is conglomerate only in some layers and has a rusty color on the weathered surface. The dip is almos* south-east at fifty-five degrees. Ten feet of brownish sandstone are exposed at fifteen feet above this conglomerate, but no further exposure occurs in a horizontal space of about 1175 feet. Fragments with Chemung fossils are abundant in the first 500 feet of this interval, but beyond that they become less plenty and soon disappear, so that proof of Chemung is not likely to abound in the upper half of this interval. The bottom of the undoubted Vespertine, the "Quarry rock " of Lesley 1887.] 1^5 [Stevenson. is exposed at the end of this interval. Tlie exposure shows only five feet, but the fragments indicate a thickness of fully thirty feet. The rock is light gray, some parts are very hard and in thick layers, but others are in thin layers ; the dip is nearly fifty degrees. This rock is succeeded by shales ill-exposed and extending nearly 400 feet to the eighth mile post. The exposure is so poor that the dip could not be ascertained, but it may be taken as averaging not far from thirty- five degrees. Here belong the coal beds, to which reference has been made, and one of them is mined on the opposite side of the river. From the eighth mile post for 1175 feet, everything is practically con- cealed. Clearly enough the interval is occupied by gray to bluish sand- stones and shales, but there is no exhibition good enough to tell the rate of dip. An uncertain measurement almost midway in the interval made the rate not far from twenty-five degrees. As the next exposure shows a dip of only fifteen degrees, the dip in this concealed interval may be averaged at twenty degrees. This is succeeded by a reddish or bluish sandstone, fortj^ feet thick, which is well shown in a cliff on the hillside but does not appear in any of the railroad cuts. The dip is fifteen degrees. No further exposure occurs for 200 feet, bej^ond which comes a sand- stone with dip of ten degrees. This is shown as a cliff, but it was not seen in the cuts ; it continues for a horizontal distance of 600 feet. The color varies from gray to rusty brown and the rock is fine-grained but irregular in bedding. This is succeeded bj^ a concealed interval of 375 feet, in which the dip is twelve degrees ; beyond it one comes to red sandy shale extending 300 feet with dip of twelve degrees. Upon this rests a red to gray, irregu- larly bedded sandstone continuing for 200 feet, also with dip of twelve degrees. After a concealed space of ninety feet, sandstone, gray to red, is reached, which, with dip of fourteen degrees, extends for 300 feet along the track. It contains many thin beds of red shale and some insignificant beds, or rather streaks, of impure limestone or possibly only calcareous sandstone. Above this are alternations ot red sandstone and red shale, with dip of fifteen degrees and continuing for 2300 feet to Back creek just beyond Tyler's coal switch. Next comes the geodal limestone, to which reference has been made so frequently and which belongs at the base of the Knox limestone. Evidently the fault of Walker mountain has been crossed ; so the succession may be summarized. It is as follows : Lower Silurian. Limestone in bank of Back creek 25' The Walker Mountain, fault.

Sandstones, flaggy, not well shown 160' The "Walker Mountain fault passes very near the mouth of Back creek and is crossed by that stream at a little way west from the railroad. The exposure of the shales is practically continuous to the creek, but there were seen none of the yellow shales observed on the Dublin and Pearis- burg pike. The line of fault is therefore drawn directly under the lime- stone of the Knox group. Southward from Back creek for nearly a mile, the whole region near the railway is covered with a thick deposit of terrace debris, and the only exposure is in a cut at about 1000 feet from the end of the Back creek trestle, where a veined, somewhat brecciated limestone is shown associated with light drab shales, all belonging to the lower part of the Knox lime- stone. The next exposure is in a stream at, say, 600 feet south from Bel- spring station, where limestones and shales are shown. Similar beds are exposed on the railroad at about 300 feet further, where the shales, or rather shaly limestones, weather light yellow or grayish white. The limestone is drab to blue, is somewhat silicious, is veined with white spar and is more or less brecciated. The dip is south-eastward at about eighteen degrees. But the dip quickly becomes flexuous and these shales and lime- stones remain in sight to the fifth mile post. The irregular dip continues for half a mile further, but thence for a mile or two, to within three miles and a half of New River station, the more prevalent dip is south-eastward, so that the massive limestones with large nodules of chert are brought down. These thicker beds are separated by impure shaly limestones which weather into clays, usually yellowish red. The dip becomes north-westward at three miles and a half from New River station, and this direction is kept forprobably a mile along the road, which follows the strike for much of the distance. In the deep cuts about two miles and a half fi'om New River station, the beds are in great disor- der and consist of the shaly limestones which the reversed dip has brought to the surface again. Thence no exposure was found until the first mile 1887.] ^ ^ ^ [Stevenson. post was reached, Tvhere somewhat higher beds are shown in very con- fused stratification. From this place to the main line of the Norfork and Western railroad at Xew River bridge, the thick bedded limestones of the Knox group are bent and folded to a degree, which one would think hardly possible in rock of that character, yet so far as could be ascertained no fractures exist. Returning to the New River gap through "Walker mountain and crossing the river so as to take the road leading across Price mountain to Chris- tiansburg, one comes to the Vespertine as the road rises to the river hill. But exposures quickly become indefinite and little is shown until beyond Price's fork in the road, about five miles west from Blacksburg. The only exposures in this interval of four or five miles are of drab shales such as were seen in the cut south from Belspring station on the New River branch of the Norfolk and Western railroad. The whole area for several miles from the river is covered with the terrace deposit, which is very deep. The Knox limestones are shown on the Blacksburg road, as well as to a short distance south from it, dipping southwardly ; but a synclinal is crossed between that road and the northerly fault of Price's mountain, so that the limestones, where last seen, dip away from the fault. Red shales of the Lower Carboniferous, such as those seen on New river, are shown on the flank of Price mountain, and are underlaid by the coal- bearing Vespertine. The coal beds are mined along a fork of Strouble's creek on the northerly side of the Price Mountain anticlinal. Several abandoned openings were seen on the Bruce property, one of which showed 1.

It bears much resemblance to cannel. It is mined extensively and is wagoned to Bang's station, whence it is shipped to neighboring stations. The rocks alongside of the road dip at fifty-five degrees as the crest of the anticlinal is approached ; but on the other side near Mr. Church's mine, the dip in the southerly direction is barely twenty degrees. Thence Stevenson.] iUo [March 18, nothing was seen aside from the shales and sandstones until the Blacks- burg and Christiansburg road was reached, on which the southerly fault of Price's mountain was crossed at a little way north from Mr. Stevens's house, where Umbral shales and Knox limestones are in contact. Directly north from Mr. Stevens's house, the road from the coal mines unites with that leading northward to Blacksburg and Newport. Expo- sures are very indefinite on this road as it crosses Price's mountain, though the Lower Carboniferous shales are shown in several shallow cuts. No coal blossoms were seen along the road and no coal is mined near it. The Knox limestones are reached at somewhat more than two miles south from Blacksburg, but exposures on this old erosion plane are few and widely separated, so that nothing can be told respecting the character of the rocks. The place of the "Walker Mountain fault is about half a mile south from Tom's creek, where Umbral shales are thrown over to almost vertical dip, while the Knox limestones are shown within a few rods with much gentler dip. Coal is mined at several places on Tom's creek both above and below this road. The dip at a pit immediately south from the creek is twenty-fire degrees toward the south-east. The bed is thin, being reported as follows : Coal V Clay 0' 6" Coal 1' 6" but the bed is thicker at other pits and, at some, it has three feet of work- able coal. The crush has been severe and the coal of the Tom's creek mines is so loosely laminated that the laminte are easily separated by the fingers. The dip becomes gentler as the road ascends Brush or Little Walker mountain. Sandstones with dip of ten to twelve degrees make the road- bed for a long distance and form spurs extending southward from the mountain. The passage to the Chemung is through these yellowish sand- stones, which appear to be thicker than on New river. The upper beds of the Chemung are not shown near the road ; fragments of the upper con- glomerate are numerous, but the rock was not seen in place. It however forms the crest of Brush mountain and Chemung fossils are numerous at several exposures on the northerly slope as the road descends to "Pov- erty flats," the "Poor valley" between the Walker mountains. The conditions in this valley, digged out of Chemung, Hamilton and Clinton shales, differ in no way from those in the "Poor valleys" already described. Exposures show nothing but shales. The Clinton ore was mined here many years ago for the furnace at New- port, in Giles county, but nothing can be learned now respecting either its quantity or quality. Medina forms the southerly slope of Gap or Big Walker mountain and on the summit is dipping south-eastwardly at sixty degrees. 1887.] -'-"*^ [Osborn. The Triassie Mammals, Dromatlieriam and Microconodon. By Henry F. Osborn, Sc. D. {Read before the American Philosophical Society, April 15, 18S7.) The mammaliaa jaws discovered by Professor Emmons in the Upper Triassie beds of North Carolina, and ascribed to a single genus, Droma- therium, were recently examined by the writer and found to belong to separate genera. The type mandible of Dromatherium is preserved in the Williams College Museum, and differ widely from the mandible preserved in the Museum of the Philadelphia Academy. These differences have already been pointed out,* but require to be more fully stated, as both Professors Marsh and Cope have expressed doubts as to the distinct sepa- ration of these genera. The accompanying lithographic figures also bring out the characteristic features of these mandibles much more fully than in the pen drawings which accompanied the earlier description. In many respects these genera agree with each other, and stand sepa- rate from the Jurassic mammals of both England and America. There is, first, a considerable diastema behind the canine, a very rare feature in the division of Mesozoic mammals to which these genera belong, although always present in the division to which Plagianlax and its allies belong, viz., the sub-order Multituberculata Cope. Dromatherimn has three premolars and seven molars, but the number in Microconodon is quite uncertain, as only four of the series are preserved. The molars agree in one particular, which separates them widely from other Mesozoic genera, viz., in the imperfect division of the fangs. This division is indicated merely by a depression at the base of the crown, as in the genus Dimetrodon, among the Theromorph reptiles. In all other respects these mandibular rami differ widely. The Micro- conodon ramus is two-thirds the length of that of Dromatherium ; it is flat- tened and slender, with a nearly straight lower border beneath the molar alveoli, and a characteristic depression of the border which possibly rep- resents the angle of the jaw as in Prof. Owen's genus Peraimis. The coronoid process is low and the vertical diameter of the jaw at this point is very narrow. This ramus offers a great contrast to that of Dromatheri- um, which is very stout and convex with a thick lower border, pro- jecting widely from the matrix, an elevated coronoid process and has the curvature of the lower border unbroken by any downward projection. If these differences may be given merely a specific value, and attributed in part to the fact that the Microconodon jaw is seen upon the outer surface, and that of Dromatherium upon the inner surface, let us compare closely the teeth in the two genera., Unfortunately the canine and incisors of the * Proceedings of the Academy of Natural Sciences of Philadelphia, 18.S6. p. 359. I find upon a second examination of Prof. Emmons' original flgiire, that I did unintention- ally criticise it too severely in the former article, p. 359. While far from accurate the figure is not so misleading as I at first supposed. Osbom.] J- J- 'J [April 15, Microconodon ramus are wanting. We first observe that the premolars of Dromatherium are styloid and procumbent ; if erect they would rise> above the level of the molars ; they have no trace of a cingulum. In the other genus the premolars are subconical and, although erect, they do not reach the level of the molar tips ; they show a faint posterior cingulum, and the third premolar has the same evidence of a division of the fang which is seen in the molars, while in Dromatherium there is no trace of such a depression, but a distinct groove on the postero-internal face of the tooth reaching nearly to the summit. The molars of Dromatherium are narrow and lofty ; the general pattern of the crown consists of a single main cone with a high anterior and lower posterior accessory cusp upon its slopes ; but these cusps are very irregular in disposition. For exam- ple, in the second molar there are two anterior cusps ; in the third molar the posterior cusp is nearly as large as the main cusp ; in the fifth molar there is a trace of a postero-external cusp ; in the last molar both the anterior and posterior cusps are distinctly bifid at the tip. In Microcono- don, on the other hand, the molars are comparatively low and broad, with a low anterior and higher posterior accessory cusp ; these cusps are regu- lar and very prominent ; there is also a well-marked posterior cingulum, which cannot be distinguished in the corresponding molars of the other genus. Although the two posterior molars are wanting in Microconodon, the rise of the corouoid probably marks the position of the last molar ; taking this estimate of the posterior point of the molar-premolar series and com- paring it with the length of the series in Dromatherium, we find that while the ramus of one genus is only two-thirds the length of the ether, the total space occupied by the molar-premolar series is very nearly the same. Esti- mated in another way, the molar-premolar series of Microconodon is a little less than one-half the entire length of the jaw {f^), while that of the other genus is exactly one-third the length of the jaw. This discrepancy is due to the difference in the proportions of the molars ; in one genus they are low and broad at the base, in the other they are unusually high and com- pressed. It is difficult at present to assign any systematic position to either of these genera. Dromatherium is entirely unlike any known mammal, fos- sil or recent. The form of the molars is extremely primitive both in respect to the incomplete separation of the fangs and the remarkable varia- tions in the number and size of the accessory molar cusps. In fact the molars appear to be in what may be called an experimental stage of struc- ture. The accessory cusps are sometimes large and distinct, as in the third true molar ; sometimes minute like needle points, as in the second molar. The incomplete separation of the fangs is a reptilian character, which correlated with the styloid premolars and recurved canine-incisor series, place Dromatherium very remote from any of the known Mesozoic mam mals. Microconodon, on the other hand, is a somewhat more "recent" type, the premolars have the trace of a low posterior heel, and the molars Vol rxrv.

The Relation of Aerolites to Shooting Stars. By Professor Daniel Kirkioood. ■iEead before the American Philosophical Society, April 15, 1887. ) The writer more than twenty years since gave reasons for believing that shooting stars, fire balls and meteoric stones move together in the same orbits.* The facts then collected were deemed sufiicient to sustain the theory advanced, or at least to give it a high degree of probability. This view has been rejected, however, by several eminent astronomers, and especially by the present Astronomer Royal for Ireland, the distinguished author of " The Story of the Heavens." He remarks: "It is a notice- able circumstance that the great meteoric showers seem never yet to have succeeded in projecting a missile which has reached the earth's surface, * Meteoric Astr,, Chap. v. Kirkwood.] ±1^ [April 15, Out of the myriads of Leonids, of Perseids, or of Andromedes, not one particle has ever been seized and identified. Those bodies which do fall from the sky to the earth, and which we call meteorites, never come from the great showers, so far as we know. They seem indeed to be phenomena of quite a diiierent character to the periodic meteors" (Story of the Heavens, p. 349). In pointing out the coincidence in the epochs of shooting stars and me- teoric stones,* the present writer neglected to assign an obvious reason for the fact that star showers are so seldom observed at the same time with the fall of aerolites : a majority of the latter have been seen in the day time, when ordinary shooting stars would be invisible. At night, how- ever, the phenomena have more than once occurred at exactly the same time. The writer called special attention to one of these epochs as long since as 1881. f In describing the shower of April meteors as it occurred in the year 1094, the historian says: "At this period so many stars fell from heaven that they could not be counted. In France the inhabitants were amazed to see one of them of great size, fall to the earth, and they poured water on the spot, when to their exceeding astonishment, smoke issued from the ground with a hissing noise. "| A few other examples are given below : (1.) During the meteoric display which continued through three consec- utive nights in the latter part of October, A. D. 585, a globe of fire, spark- ling, and producing a great noise, fell upon the earth. ^ (2.) A simultaneous fall of aerolites and shooting stars is indicated by the phenomena of 1029, as described in the catalogues of Herrick and Quetelet. (3.) But without quoting other records which imply the existence of aerolites and ordinary meteoric matter in the same streams or clusters, it is sufficient to refer to the recent and very decisive phenomena of Novem- ber 27, 1885. II During the periodic star shower from the fragments of Biela's comet a mass of meteoric iron weighing about ten pounds was seen to fall near Mazapil, Mexico, in lat. 24° 35' K, long. 101° 56' 45" W. from Greenwich. The evidence afforded by the phenomena of 1094 and 1885, apart from the other cases cited, renders the coexistence of large and small masses in the same meteo^ streams almost infinitely probable. *Metr.

S., &c. Akron, 0. (Read before the American Philosophical Society, April 1, 18S7.) Introduction. Two remarkable utterances liave recently appeared from the pens of two of the most distinguished biologists of the day in defense of a theory of evolution radically unsound and differing, as the writer thinks, from that which is held by the majority of evolutionists. The eminence of the names of these authors is suflBcieut reason to justify a consideration of the view they have advocated. It cannot be supposed that Prof. Asa Gray, of Cambridge, Mass., and Dr. W. B. Carpenter,* of London, would put forward statements all the aspects of which they had not fully considered, and all the legitimate conclusions from which they were not prepared to maintain. Yet both these distinguished writers have enunciated a view of evolution fraught with momentous consequences to biology. So momentous indeed are they that they exclude (if the views in question are well founded) a very large part of the field of investigation now before the biologist from the lawful domain of natural science and relegate it to another department of enquiry. The nature and direction of organic variation are subjects which have become prominent during the intellectual ferment excited by the publica- tion of the '"Origin of Species." As a fact variation is admitted by all evolutionists. It is indeed the cardinal fact on which all theories of evolution do and must depend. And both the -writers above men- tioned alike admit its reality and its importance. Both allow' or tacitly assume that there runs through all organic nature a capability of varying from generation to generation — that under the superficial and obvious resemblance existing between parent and offspring therL! lie deeper and less easily discerned distinctions which differentiate the one from the other and accumulate in certain directions from age to age. This capacity, manifesting itself in the fact of variation, when encouraged or repressed by the action of natural or other selection has— so Darwin maintained — resulted in the extinction of old and the production of new species. But while agreeing thus far with most evolutionists the two writers in question express views on variation that are remarkable in the following respect. Instead of proceeding on the ground that variation occurs, or * These pages were written before science had been deprived of the services of this veteran laborer and leader in biological research by the deplorable accident which caused his death.

Yet further, in their view the changes thus produced in an organism are uniformly of a beneficial kind. That I may not be subject to the charge of misrepresentation I quote the following extracts from the writers referred to. In a paper entitled " On an Abyssal Type of the genus OrhitoUtes ; a Study in the Theory of Descent," published in the Philosophical Trans- actions, for 1883. Dr. Carpenter remarks, after detailing the variation exhibited by the forms of OrbitoUtes, "that no exercise of natural selec- tion could produce the successive changes presented in the evolutionary history of the group." "And," he adds, " as all these earlier forms still flourish under conditions which, so far as can be ascertained, are precisely the same, there is no ground to believe that anyone of them is better fitted to survive than another." " To me therefore it appears that the doctrine of natural selection can give no account of either the origin or the perpetua- tion of those several types of foraminiferal structure which form the ascending series that culminates in OrbitoUtes complanatus." " On the other hand there seems traceable through the series a plan so obvious and definite as to exclude the notion of "casual or aimless variation." "Everything in their history shows a well-marked progressive tendency along a definite line towards a highly specialized type of structure in the calcareous fabric." The significance of these remarks is unmistakable. The writer is evi- dently maintaining that alongside of the capacity for variation there acts some power guiding the ensuing variation along a definite course to a definite end. One expression in the above passage calls for a passing remark. In saying that the doctrine of natural selection can give no account of the origin of these types Dr. Carpenter appears to have overlooked the fact that no evolutionist attributes the origin of varietal or specific forms to this source. Tlieir origin must be sought in variation. Natural selection is only the means of preserving and perpetuating or of destroying and eliminating them. This remark would perhaps be impertinent were it not that other expressions in the same essay also apparently ignore the part played by variation in every accepted theory of evolution. For example, we read, "Those who find in natural selection or the survival of the fittest an all-sufficient explanation of the origin of species seem to have forgotten that before natural selection can operate there must be a range of varietal forms to select from." "No exercise of natural selec- tion could produce the successive changes presented in the evolutionary history of the typical OrhitoUtes from Cornospira to SpiroloeuUna thence to PeneropUs, to OrbicuUna, to the simple and then to the complex forms of OrbitoUtes." There is in this passage a singular omission of all reference to the fact 1887.1 ^^^ [Claypole. and function of variation, the existence of -wliich no naturalist can doubt, be his explanation what it may. The second utterance of opinion to which I have alluded is contained in a letter from Prof. Asa Gray, printed in " Nature " (Jan. 25, 1883). The letter itself is written in reply to some remarks made by Mr. G. J. Romanes in an article in the " Contemporary Review " for October, 1883. It is difficult to quote any particular passages in exemplification of the views of Prof. Gray, which are rather implied than expressed. The main point of difference between the two writers is however the denial by Mr. Romanes that "the facts of organic nature furnish evidence of design other and better than any of the facts of inorganic nature," and the main- tainance by Prof. Gray that this denial rests on no good foundation. In some passages indeed the latter writer goes apparently even farther than this merely negative position and implies, if no more, that in his opinion variation has been beneficently guided by intelligence. It is difficult to extract any other meaning from the following passage : " The evidence ot design may be irresistible in cases where we cannot indicate its limits. We can only infer with greater or less probability according to circum- stances and especially according to relation to ends. Better evidence than that of exquisite adaptation of means to ends is seldom if ever attainable of human intention and in the nature of the case it is the only kind of evi- dence which is scientifically available in regard to superhuman intention. With what propriety then can it be affirmed that organic nature furnishes no other and no better evidence of underlying intelligence than inorganic nature? The evidence is certainly other and to our thinking better." It seems impossible to attribute to the author of this passage any inten- tion other than that already expressed ; viz. : that alongside of the capacity for variation there acts some power guiding the ensuing actual variation along a definite course to a definite end. If any doubt yet exists concerning Dr. Gray's meaning, such doubt must be altogether removed by the following extract. In a notice of Dr. Carpenter's paper in the "American Journal of Science, " for April, 1884, Prof. Gray says : "Variation has been led along certain beneficial lines like a stream along certain definite and useful lines of irrigation." The expression "has, been led" is rather indefinite, but can scarcely mean less and may mean much more than I have above attributed to its author. To assert that variation has been led along definite lines implies the coaction of some guiding power. To assert that these lines are always beneficial to the variant organism implies a postulate of vast magnitude and one whose admission is infinitely difficult in face of the phenomena of organic nature. II. Definition of Terms. The purpose of this paper is in the first place to examine so much of the evidence of nature on this point as shall be sufficient to show that the Claypolc] lit) [April 1, theory of evolution favored by the writers above quoted is not in harmony with the facts, and in the second place to prove that, taken as a whole, the phenomena of nature in the organic world are much more easily ex- plained by the principle of indefinite variation.* To prevent ambiguity and perhaps misunderstanding it will be well to define at the outset the principal terms that will be employed in this paper. "Variation" will be here taken to mean all deviations of every kind and degree from perfect resemblance to the immediate parents of the organism whether animal or vegetable. This is the widest signification which it is possible to give and with no other can any useful conclusion be reached. Any limitation can only result in invalidating the argument because it would confine the discussion to a special part of the subject indicated by such limitation. The universal signification to be here employed is also the only fair interpretation that can be accepted by all Evolutionists. The organism in which such Variation is supposed possible will be called a "Variable." The term is borrowed from mathematics and will be understood to mean an animal or plant possessing the capability of varying whether that capability be latent or active. At any one given instant this power may be always considered latent, time being a necessary element in actual variation. When from any cause this possible variation has become actual and the organism shows progressive resulting changes, this organism may be called a "Variant." And again when a series of changes is complete or when any particular phase is intended the organism in that stage may be called a " Variate." Thus the term "Variable " will indicate that change is possible ; "Variant," that such change is in process, and "A^ariate," that it is complete, at least for the time, in any given organism. The term "beneficial" will be employed to characterize any change that conduces to the longer life of the variant organism ; this being, for the most part, and other things being equal, the greatest benefit that can accrue to it. I do not deny that there are exceptional cases in which other inherited or acquired advantages may outweigh even this usually supreme one. But almost always a long life may be considered the most conducive to the continuance of the species as it indicates vigor in the in- dividual and increases the chances of multiplication. The expression " Tendency to Variation," sometimes employed by writers on this subject, either commits an author to the views here opposed (for such tendency must have a cause) or it is meaningless. When varia- tion occurs it must have been antecedently possible. But its occurrence is our only proof of this possibility. Of any "tendency to variation " in- herent in the organism we have no proof whatever. For all that we *The possible assertion that variation is always beneficial in consequence of some cause underlying the constitution of the organic and inorganic worlds and their relation to one another will not be here considered. No writer has, so far as I am aware, ever distinctly enounced it and moreover it will be excluded if, as I hope, I shall succeed in showing that as a fact variation is not always beneficial. 1887.] 11* [Cla5T)ole. know to the contrary an organism is capable ot existing unvaried for any length of time, through generation after generation, without showing the least tendency toward any other form. As well might the mechanician or the astronomer speak of a " tendency to motion " in the heavenly bodies because he sees them all in a state of active movement. For anything that he knows to the contrary all the matter in the Universe may be capable of lying at rest for countless ages. Matter itself has no tendency to motion or to rest. It is absolutely a creature of conditions and of circumstances. 80 we have reason to believe that organisms have no tendencj' to variation or to invariance. Changes if they occur, or their absence if they do not, are simply accidents of the environment. The astronomer sees all mat- ter in motion and comes almost instinctively to the belief that the two are inseparable. The biologist sees every organism varying and grows un- consciously into the opinion that variation Is a necessary concomitant of life. Both are equally unphilosophical. Absolute rest may be almost in- conceivable to the physicist and absolute invariance to the naturalist. Yet both so far as we can know, are thinkable and possible, and both may form a part of the actual scheme of Nature. We see no ground for the expression "tendency to variation." iir. Vakiatiox not Always Beneficial. In the consideration of this part of the subject it will be manifestly impossible within due limits to even notice any large portion of the facts that bear more or less directly on the question. No attempt will therefore be made to take a wide range. Nor is this necessary for the argument. If sufficient proofs can be adduced to show that in some cases the actual variation is prejudicial to the variant the purpose will be served. Yea, more, in logical strictness if a single such case can be established the advocacy of definite variation in a uniformly beneficial direction becomes futile. For unless such beneficial variation be abso- lutely constant and unfailing no object can be attained by maintaining its occurrence in any single instance. I propose therefore to limit myself to the presentation of a few of the more conspicuous instances of prejudicial variation, of which some one or more must during a lifetime fall within the cognizance of all who take any interest in the study of Nature. I may here remark in passing that of the two authors quoted at the out- set. Prof. Gray does not give a single instance in support of the proposi- tion which he is maintaining and that the only one under discussion by Dr. Carpenter is drawn from the lowest class and one of the most obscure in the animal kingdom — the Rhizopods — among the Protozoa. 1. Variation in color. — Among the many variations in color constantly occurring among animals is the production of a white descendant from colored ancestors. Claypole.] 1-*-^ [April 1, Every naturalist knows that among wild land animals, with some few exceptions, this color is exceedingly rare. The cause of this rarity is obvi- ous. In a green world a white individual is very conspicuous. Such an animal has much less chance of escaping from its enemies if pursued, or of capturing its prej' if a pursiier, than one whose color is more in har- mony with its surroundings. Hence its prospects of living and of leaving offspring are proportionally reduced. And in places where green is not the prevailing color, we find the wild animals dressed in harmony with their surroundings. In the Polar regions and in winter the fur-hearing inhabitants are clad in white. No other livery would give them so good a chance of life. In dry and sandy deserts the prevailing color of the fur of the residents is nearly the same as that of the sand. Nevertheless in the parts of the world that are clad in green, white individuals are frequently produced. And we can hardly doubt that similar exceptions to the prevalent color occur elsewhere. Thus we find white deer, white mice, white blackbirds and white wild horses. But their extreme rarity shows that there is some check to their multiplication. And in asserting that this check is nothing more than early destruction in consequence of their conspicuousness I am not going beyond what has often been ob- served in cases falling within our notice. "On some parts of the conti- nent," says Darwin, "persons are warned not to keep white pigeons" on account of their liability to destruction by hawks. (Origin of Species, 1860, p. 84.) And when to these disadvantages we add those of deafness, of epilepsy and of other diseases which often accompany the white color in animals, cats for example, we find an accumulating variation which cannot fail of being deeply prejudicial to the variant.* Darwin says, " Cats with blue eyes are almost invariably deaf." He has collected a great number ot cases showing the disadvantages to which animals are liable whose hair is partially or altogether white, f Another instance is afforded by some pet rats kept by a relative of the author's, which were with one exception wholly white. They all recently became troubled with bronchitis or some similar complaint, and the sound of their breathing was so unpleasant that they were destroyed except one. The sole survivor was the rat that was not entirely white. This one, though sharing in the disease, was much less severely affected. The case of albinoes may fairly be cited here. In this form of variates not only is the increased color-risk a source of danger, but the imperfect sight so frequently accompanying the whiteness is almost equally preju- dicial . In regard to the vegetable kingdom similar facts may be given. Every gardener is aware that the white seedlings that so frequently come up, in a field of maize for instance, usually die down and yield no seed. Here, as in the case of albinoes among animals, the radical cause of prejudicial • See examples of this published in various numbers of Nature, 1884. tSee "Animals and Plants under Domestication," "Vol. i, p. 330. 1887.] -L-LJ [Claypole. results seems to be the want of the usual vigor, probably in consequence of arrested development or of imperfect ante-natal nutrition — two of tlie most fruitful sources of variation. 2. Variation in strength. — It comes within the observation of all that among animals great difference of bodily strength exists. This is easily noticed in those that are reared for draught. Though less conspicuous the fact is equally true of the savage species. Now this deficiency of power is prejudicial to the variate. The load which one horse can draw with ease is a severe tax on another. A battle between two wild beasts is decided, other things being equal, to the injury and often the death of the weaker. Indeed the prejudicial effect ensuing upon bodily weakness is so evident that Jong proof is superfluous. Nor is the deficiency of mental power any less prejudicial. Every one accustomed to observe animals must have noted great difierence in their intelligence. Among domesticated species one individual shows mental power fully entitled to the name of reason, while another, perhaps of the same brood, manifests so little that education is impossible. A well- known horse-trainer once told me that though he never failed to train a horse when he took him in hand, yet there were but few that he could train at all, and that he could, in a very short time, pick out and reject the many with which success would be impossible. Some rats are so cunning that to catch them requires all the craft and skill of the house- holder. Others are so silly that they walk into the trap the first time it is set, and are killed to their great prejudice. The sagacity of bears in avoiding the snare is sometimes wonderful, compelling the belief that they have mastered its construction and found out how to take the bait and yet avoid the danger. Others show no subtlety of this kind, and are caught and killed with ease. Such tales may be found in any work on the habits of animals, and need not be repeated here. But enough has been said to show that the range of variation of the mental faculties of animals is great, and that while the higher degrees confer much advantage on their possessors, the lower are so far inferior as to be seriously prejudicial. Though pertinent to the argument, it is scarcely worth the time to point out the frequent occurrence of similar prejudicial variation in the human species where the range of the mental faculties is from idiocy upward. In our present state of civilization this disadvantage is partially and temporarily neutralized by the humane sentiment prevailing in society which counteracts the laws of natural selection as they operate among other animals. Yet all such deficiency of power is seriously and often fatally prejudicial 3. Variation in the senses. — Whatever prejudicial effect ensues from de- ficiency of bodily or mental strength is aggravated when this deficiency takes the form of the absence of one or more of the senses. Yet animals are not infrequently born blind or deaf, and the probable reason wliy such cases are seldom seen is that the absence is so prejudicial as to be soon fatal. Claypole.] 1^^ [April 1, In the consideration of this subject we must bear in mind that to obtain evidence from wild animals is difficult, because they are not under our supervision. Hence it is necessary in most instances to quote facts from animals kept in domestication. But abundance of cases have been recorded to show that similar prejudicial variation occurs among animals in the wild state. 4. Variation in form. — Under this head I maj^ quote the well-known case of the Ancon or otter sheep of Mass., " which originated in 1791 with a single specimen having short crooked legs and a long back like a turn- spit dog." This change in a natural state would hare been extremely prejudicial to so active an animal. But under human control the very de- fect was, for a time, a convenience to the farmer, who found that these sheep could not leap over his fences. Hence he preserved and bred them. But the Merino superseded the Ancon, and without the preserving care of man the latter soon disappeared, as it would have done much earlier in a state of nature. The once well-known turnspit dog supplies another case in point. A friend of the writer once had a kitten which was born without any hind legs — a defect which had occurred in several litters dropped by tlie same cat. It lived for some years to my knowledge, and may be living still. When I last saw it it was nearlj^ or quite full grown. Its difficulty of motion was great. Yet T have seen it get up on a chair, and when it walked it threw up its hind quarters and moved with a series of jumps, much as a boy moves when walking on his hands with his feet in the air. Without the care of man so defective an animal must soon have starved for want of locomotive power. From the above instances the transition is slight to that of monsters. Indeed the line between these and malformation so great as that last mentioned is not easily drawn. Nor do I care to insist on the distinction. The only obvious difference between them lies in the transmission or arrest of the defect. In most cases malformation so serious necessarily ends with the individual. Some may feel unwilling to admit the pertinence of monsters to the present argument. But they cannot logicall}^ be excluded. They are only the extreme cases in which the variation is so prejudicial that life is usually short and transmission impossible. No department of either the animal or the vegetable kingdom is free from the occasional appearance of these usually inexplicable forms. Five-legged calves, sheep with two tails, two-headed fowls and other such cases of malformation are often announced. And after making all due allowance for mere external abnor- mality there remain enough instances certified by anatomical demonstration to show that the birth of such monsters is by no means rare.* "The Museum of Michigan University contains a double-headed milk * Abundant evidence tliat the human species is not less liable than others to this kind of variation may be seen on the shelves of ahuost any medical museum and especially on those of the Royal College of Surgeons of Loudon. 1887.] . J---"- [Claj'pole. snake (Ophibohis tnangulus) of which the remainder ot the body appears to be perfectly normal. Another case is recorded by Prof. Wyman * of a water snake (Tropidonotus sipedon) with two heads and two tails, and a similar case as well as one of a five-legged frog is reported by Mr. Kings- ley.f Mr. Ryder also calls attention:): to a specimen of the pickerel frog (Bana palustris) with five limbs or rather an additional pair of hind limbs fused together. This leg had six toes and its digital formula might be written— 5, 4, 3, 3, 4, 5. Among insects such monstrous forms have been observed. " Numerous instances of supernumerary legs and antennte are recorded. The antennte are sometimes double but more Sbmmonly the legs." Asmuss has col- lected eight examples and in six of these the parts on one side are treble. "Newport relates that from a single coxa of Scarites pyrachmon on the left side two trochanters originated. The anterior supported the true protho- racic leg, while the posterior carried two legs each as well formed as the first. "§ "Other deformities occur in the wings. Cases of hermaphroditism are on record in which one wing bears the colors of the male insect and the other those of the female. Sometimes the wings are aborted or deformed." Most persons who have had much experience in the breeding of animals can recall similar instances. At a recent meeting of the American Entomological Society a mon- strosity was noted in a longicorn beetle of the genus Acmceops in which the left front leg has three tarsi. A specimen in the collection of Prof. Riley {Isosoma tritici) was also described in which the fore wings are rep- resented by rudimentary pads while the hind wings are fully developed (Science, Dec. 5, 1884, p. v). Mr. J. A. Ryder has recenily recorded similar malformation among lobsters under his observation such as the absence of eyes, partial fusion ot two bodies, fusion of the eyes on the median line. These changes were coincident with the stage of gastrulation.|| In lecturing on the denizens of the aqueous kingdom, on Friday last, at the Royal Aquarium, Mr. A. Carter referred to deformities that exist among fish. In 1885 and 1886 he had examined thousands of salmon and trout fry at South Kensington, on their emerging from the ova, and found one case of deformity in every thousand, and one case of monstrosity such as twin and dual-headed fish in every four thousand."^ Though as said above these forms are usually inexplicable, yet their dependence on the chances of outside conditions in some instances at least is, indicated in the following passage taken from Darwin's Animal and Plants under Domestication (p. 279). *Proe. of Bost.

St. Hilaire, and recently from those of Dareste and others, that eggs of the fowl if shaken, placed upright, per- forated, covered in part with varnish produce monstrous chickens. Now these monstrosities may be said to be directly caused by such unnatural conditions, but the modification thus induced is not of a definite nature." It is not by any means unlikely that the indefiniteness to which the great naturalist here alludes is a mere consequence of our want of knowl- edge of this obscure subject and not inherent in nature. The recent ex- periments of Warynski & Fol, as quoted in the Journal of the Royal Microscopical Society (June, 1866, p. 401), tend strongly to confirm this opinion. These zoologists have succeeded in producing double hearts in chickens by artificial means. The mode of procedure is as follows : " The blunt edge of a scalpel is carefully and lightly drawn backwards along an embryo between twenty-four and thirty-six hours old from just behind the head without injuring any tissues. If all goes well the embryo will con- tinue to develop normally with the exception of possessing two hearts." The authors quoted were also able to produce other abnormalities in a similar manner. In the absence of any evidence to the contrary it is more logical to infer that all such cases owe their origin to similar causes, antenatal accidents, not yet discoverable.* Turning now to the vegetable kingdom we find monstrous forms by no means rare. Not seldom among wild plants the botanist finds flowers in which one portion in hypertrophied to the injury or the atrophy of another or of others. When this atrophy includes the essential organs, such as the anthers or stigmas, it results in sterility and the extinction of the species along that line. Human selection has enormously increased this form of variation. Most of the double flowers of the gardener are monsters to the anatomist. The showy double corolla is obtained at the cost of more im- portant though less conspicuous organs. To quote special cases is here needless. Abundance of them will occur to every naturalist or may be found in works on the subject. 5. Moral variation. — Another phase of the subject should not be passed over though any adequate discussion of it is not practicable here. Most naturalists will sigree that the moral development of an organism may be prejudicial. Animals born in domestication are not seldom so ill-tempered or obstinate that little or nothing can be made of them. Horses, subject to vice, as it is termed, are sold from hand to hand, lower and lower in the labor scale, until they end by being employed as drudges in the hard- est and most menial tasks which exhaust their strength and kill them off before their time Dogs, too, are often met with which show a disposition so ferocious or uncertain that their owners are compelled to kill them from a regard to their own safety or to that of others. And the testimony of • For some curious illustrations of another but kindred topic in this connection see a paper on the " Disadvantagesof the upright position in man," by Dr. E. Clevenger, in the American Naturalist for 18S4. 1887.J -'■'"^ [Claypole. the tamers of wild animals proves that the same is true among them. The temper of tamed elephants,' of tamed lions (so-called), and of other ■wild beasts indicates a difference of moral qualities quite equal to what we see in the domesticated species. The difference is often very conspicuous in members of the same litter. The tendency to vice born in many individuals among mankind and growing with age — the inheritance from vicious ancestors — impels its pos- sessor to acts which shorten his days and are in other ways extremely pre- judicial to him. The evolutionist may assert that this result is only Xature's way of killing off those unfit to live. The philanthropist may pity them and spend time and labor and money in trying to reform them, and occasionallj' with success. But both evolutionist and philanthropist thereby proclaim their belief that the moral tendencies developed in these individuals are highly prejudicial and often fatal. They are, however, the outcome of environment of themselves and their ancestors. They are effects of the variability of the organism moulded by circumstances. They are variates whose variation is hostile to their civilized surroundings and leads to extinction. In other countries and among other circumstances they might yet be fairly in harmony with their conditions of life and might live. "The most inhuman monster of crime that ever was con- demned by a court and executed by an officer of the law would among such tribes as those of Australia surely pass for the embodiment of all excellences and rise to an uncontested chieftainship" (Bergen: "The Development Theory," p. 178). It is not relevant to reply that most of the cases here cited are accidents and should not be quoted in proof of the proposition. All such actual occurrences can be logically employed. Accident merely means happen- ing out of the expected course. If accidents happen often they partially lose that character ; if they prevail they lose it altogether. If such acci- dents as those above mentioned were advantageous to the organism they would soon be perpetuated and become the rule. All variations are acci- dents and their continuance and repetition are dependent on their advan- tage to the variant. If prejudicial they are soon eliminated and cease. " Treason doth never prosper ; what's the reason ? AVhy, if it prosperuone dare call it treason." Variation is treason to the original organism. If it can sustain itself it becomes the new organism and supersedes the old one. If not it soon goes down and is forgotten. These cases therefore are not only relevant but they are the only cases that can be cited. So quickly do all prejudicial variations die out that in the wild state only now and then can they be noted and recorded. Hence the exceptional are the only relevant and valid 'examples, and to reject them on this account would be to put out of court the only witnesses whose testimony is pertinent and by which the proposition can be estab- lished. Claypole.] l-'^: [April 1, So far, therefore, is variation from being uniformly beneficial in its results to the variable or to the variant organism, that in not a few cases that come under our observation it is positively hurtful or even fatal. And these must be only a few out of all that actually occur, inasmuch as they are necessarily taken for the most part, indeed almost entirely, from animals and plants in a condition of domestication. In domestication also a new and almost omnipotent factor entfers the problem — human selection. Now if this beneficial tendency in variation had any existence, it might be expected to show some sign of its action in species under human control. Yet here no trace of it can be detected. When a cattle-breeder attempts to develop certain features it would be evidently beneficial that the stock should vary in the required direction, for failure to do so is quickly fatal. Yet immense care and pains, and the constant elimination of faulty individuals are requisite to obtain suc- cess in the endeavor. So with plants. In the attempt to establish a new variety of cabbage or lettuce, years of work are essential and thousands of "rogues " must be pulled from the seed-bed and destroyed before the strain desired attains persistence and perpetuity. IV. Beneficial Variation and Natural Selection inconsistent. It is further worthy of remark that supporters of the theory of evolu- tion alluded to in the extracts given above can find no use in their system for the subsidiary doctrine of natural selection. Maintaining a beneficial tendency in all variation guiding it in a channel favorable to the variant, they cannot logically admit the directive influence of selection. All vari- ation being favorable, there can be no forms to be rejected. Yet one at least of the writers quoted is evidently an adherent to the doctrine and admits that its action has much influence in determining the surviving in- dividuals. Were directive beneficial variation a fact, all variates must be equally well adapted to their environment though ditferent from each other. So evident is this that proof is needless. Yet Prof. Gray himself appeals to the action of natural selection in his "Darwiniana," where with a beautiful metaphor he writes : "Natural selection is not the wind which propels the vessel, but the rudder which by friction — now on this side and now on that — shapes the course. The rudder acts while the vessel is in motion, effects nothing when it is at rest. Variation answers to the wind." Directive beneficial variation and natural selection are logical contradic- tories, and cannot both exist. The former it real must be universal. But I have shown that it is not so. Hence every evolutionist who adopts the theory of natural selection must abandon that of beneficial variation, and vice versa every adherent to the theory of beneficial variation is unable to admit the agency of natural selection in any ot its forms. 1887.] 1-5 [Claypole. V. Indefinite Variation. The instances already given have sufficiently illustrated the fact of pre- judicial variation. Of beneficial variation no evolutionist entertains any doubt. To dwell on it will therefore be needless. But there is a third aspect of the change which must not be omitted. As we have seen, the gain or loss of an organism by varying may be of any degree from that which gives the variate a surpassing advantage and predominance over his fellows to that which leads straight to extinction. In mathematical lan- guage the range of variation is from positive infinity (+ <^) through zero to negative infinity ( — oo). We must consequently admit the existence of variation which confers no advantage and inflicts no disadvantage on the variant — neutral variation it may be called. This neutral variation is an important factor in the problem, though hitherto it has received very little attention. It is capable of explaining some difficulties, of removing some anomalies. Darwin has alluded to it in a single passage : "I am inclined to suspect that we see in polymorphic genera variations in points of struc- ture which are of no service or disservice to the species " (Origin of Spe- cies, p. 46). Variation of the kind now under consideration may be often seen among the domestic animals where the struggle for existence is less severe and controlled by other laws than among the wild species. For example, six- toed cats (see "Nature" for 1886 and 1887) are a not uncommon though usu- ally a local variety. The peculiarity is freely transmitted. Yet no ill effect seems to attend the irregularity. Indeed if, as asserted, they are good mousers, it may confer a slight benefit though it detracts much from a light and graceful appearance. The same variation is not uncommon among mankind, is there also freely transmitted and is also equally inert in result. The tailless Manx cats may also be quoted in the same connec- tion,* the great range of color in the domestic animals and the manifold shapes of the leaf in many of our garden vegetables which are reproduced with certainty and seem to work neither good nor evil to the plant. Among wild species the same fact may be noted. Great difference may be seen among the leaves of any species of our forest trees attended with no perceptible advantage or disadvantage. In these cases we need not be surprised to see the variates living side by side with their unvaried ances- tors. The red maple of North America is a striking instance. This tree, whose remains are found fossil in the Miocene strata, yet lives in company with its more highly developed and later variates which do not occur in the fossil state. On this principle I would explain the fact brought forward by Dr. Car- penter of the existence of ancestral forms of Orbitolites alongside of later * In a case that recently occurred under my own observation a single kitten of a litter was born without a tail. It is now nearly full grown and appears to suffer no inconve- nience from the curtailment. In a similar way the Manx cats may have originated. Claypole.] 1-^" [April 1, variates. We have but to admit that the changes which occurred to the earlier variable organism were attended with little or no advantage, and that consequently the variable shows no diminution or tendency to extinc- tion by the side of its more specialized variate offspring and the difficulty entirely disappears. "We are compelled to admit variation of all degrees ranging from that which rapidly kills off through that which is absolutely neutral to that which puts its variates at so great an advantage above their fellows that they soon leave them behind and become the " Winners in Life's Race." VI. The Cause of Variation. For a variation so wide in its range as that above described a cause equally wide must be sought. JSio narrow or arbitrary limits can be set to the cause of a universal consequence. And what more natural or more obvious cause can be suggested than the changes constantly occurring in the environment of the organism ? This is of course not a new suggestion, but some writers on evolution seem afraid to carry it out to its full extent. They seem unwilling to abandon the organism to the uncontrolled, con- fused and seething waves of the sea of physical nature. Yet only in the ceaseless, never repeated tossing of this unresting sea can be found a cause at once sufficiently changeful and far reaching to correspond with the observed changes of the organisms that are borne upon its surface or that live among its waters. Elsewhere in vain do we look for any means of explaining them. All other known natural causes are insufficient and to resort in a difficulty to the unknown and the supernatural is to place the enquiry beyond the pale of science. In the changes of the physical world therefore and in these alone do we find a cause even presumably sufficient to account for the continual and contemporaneous changes in organic beings. It would be idle to assert that we know the precise mode of action in which the former produces the latter. So new and unexplored is this field that such knowledge is at present impossible. But with every advance we see more and more prob- ability that in the one we have the real and efficient cause of the other. Experiments on the influence of food, temperature, light and other phys- ical agents upon the modification of organisms especially during the formative part of their existence are gradually giving us a mass of infor- mation which has already greatly modified former opinions. Some forms once ranked as distinct varieties or even species are now known to be mere accidents resulting from the conditions in which part of their pre- vious existence was spent. Especially is this true with regard to the lower forms. Time and space will not allow many quotations. One or two must suffice. "The Mexican axolotl is a tadpole-like animal of considerable size which lives in the water, breathes by gills and is reproduced from eggs. 1887.1 l-J' [Claypole. In its native country this animal is not known to change its form but hatches from the egg into a minute object much like a young tadpole and gradually grows to the form and proportions of the axolotl. " Now in 1867 the astonishing fact was observed at the Jardin des Plantes that some of these animals cast their skins after crawling out of the water and began a new existence in the shape of a common salamander (Amblystoma). "This change from axolotl to salamander is accomplished in from four- teen to sixteen days and may, it seems, be always brought about in healthy specimens by placing them in shallow water and gradually diminishing the supply. "Since these axolotldescended salamanders are of precisely the same species as other salamanders in the western part of the United States it seems certain that these wild individuals are descended from axolotls and it has been suggested that a dry season or a succession of sucli seasons first caused the change to take place. If so we have here a striking instance where change of climate has produced not merely another species but another genus.* The following case given by Schmidt in his work " Descent and Dar- winism " I borrow from the author last quoted. "At Steinheim, in Wurtemberg, was once a small lake and in its waters grew countless little shellfish many of them water snails like those ot lakes and rivers at the present day. By the appropriation of the lime- stone dissolved in the water of the lake generation after generation ot these snails built up their shells only to let them fall to the bottom on the death of the little inhabitant. By this slow process a layer of shell mud was formed which has, since the deposit was made, hardened into chalk. About forty distinct layers of this chalk differing from one another slightly in appearance may be distinguished and throughout these layers are the perfectly preserved remains of many shells. The shells of each layer remain much the same throughout its thickness but toward the upper limit of each they are observed to vary, so as to approach the form which will be found in the next layer. And not only are the shells of the lowest layer so different that if the intermediate forms had not been discovered they would certainly have been called different species but there are also many among the intermediate forms themselves which if they had been found separated from the others would have been counted distinct." A figure accompanies this account which exhibits the progressive change from a flat, discoid, planorbiform shell at the base of the deposit to one with a much elevated spire at the summit. A more striking instance of invariance in monotonous conditions followed by variation on the ensual of physical change can hardly be imagined, f * Bergen, " The Development Theory." See also Buckley's " Winners in Life's Race.' ' t Mr. W. H. Edwards, of West Virginia, has recently demonstrated similar facts in re- gard to several species of the Butterflies. He has shown that several forms hitherto considered di.stinct are in reality only seasonal or other variates. See his "Butterflies of N. America " and his numerous papers on the subject in the " Canadian Entomolo- gist." Claypole.] ii^O [April 1, Facts of this kind fully and fairly considered (and geology is yearly bringing them in great numbers before us) urge us strongly to the belief that great results are constantly wrought in an organism by physical changes in its environment, and failing evidence of any other agent com- petent to effect them it is not irrational to ascribe to the same cause all the variational changes. We may then view the organism as plastic material in the hands of its environment, shaped by it entirely and absolutely, and owing its form to its external conditions. Resuming the mathematical illustration the organism is a variable quantity; the physical conditions around it are the causes of its variation ; in response to these it varies and after an uncertain period of variancy it becomes another — a Variate. In thus attributing all changes in an organism to changes in its environ- ment we are under no obligation to admit that such changes are or must be favorable. The physical world exists in total independence of the organic. It was before (>rgauization and may be after it. So far from serving or aiding it, phenomena lead us to the conclusion that animate nature is, as it were, permitted b}'- and during certain states of inanimate nature. Within certain limits of temperature, light, etc., organic beings can exist. Beyond those limits their existence is impossible. The organ- ism is, so to speak, an accident among its physical surroundings. If these are compatible with life it lives, if not it dies. It exists on sufferance and its existence is lengthened by its power of adaptation — by its variability. If physical changes ensue the organism must adapt itself to them if it can, and continue in being. If it cannot do so it becomes extinct. Summing up results thus far obtained we reach the conclusion that the doctrine of evolution by variation in a definite beneficial course is not in consonance with the facts of Nature. On the contrary we find that this variation both of animals and plants appears to take place in every direc- tion indifferently and quite without regard to the welfare of the variant. We find further that no cause is known to which these changes can be referred except the accompanying changes in the physical world. To these accordingly we refer them, conscious at the same time that the exact method of their action is as yet largely unknown. Further we find that the changes thus produced may be either beneficial, neutral or injurious to the variant organism, following, as they do, certain physical laws which are, if the expression may be allowed, totally indiffer- ent to its welfare. In a word, adopting again the language of mathematics, we may say that the Variate is a function of the original Variable depend- ent on its constitution and the conditions of its environment — that the changes between the Variable and its function, the Variate may be bene- ficial in a high or low degree ; and may lead to its extension and increase ; they may be neutral and leave the organism where they found it ; or they may be prejudicial and lead to its diminution or extinction. In every case, however, they are necessary consequences of the interaction of the laws of organic nature within and of physical nature witheutthe organism, inevitable, inexorable, fatal. 1887.] 1-" [Claypole. VII. A Possible Objection Considered. It ■will not improbably be objected that in thus attributing organic vari- ation entirely to outward agency I am going considerably bej^ond what can be proved. In the strict sense of the terra this is true. We cannot yet demonstrate all the effects of physical change on a variable organism. But we are constantly seeing more and more clearly the immense effects of physical nature on organic beings. And experiments, purposed and accidental, are gradually enabling us to trace special organic changes to their causes in inorganic nature, and thus, as it were, to correlate the kingdoms. A vast field of experiment lies here before us in the attempt not merely to correlate but to commeasure these two, not only to deter- mine what physical changes produce certain organic effects, but to measure both, to estimate and weigh them and at length to predict the organic effect of any given physical cause. And in this direction modern biological research is tending. The re- sults already obtained warrant the hope that some day the present chaos will be reduced to order, and the changes of organic nature will appear as only the outcome of contemporaneous or antecedent changes in the physi- cal world. A correlative and commensurate scale will be established. Rest in inorganic nature, if possible, will be accompanied with iuvariauce of organic nati;re, for as said above, no " tendency to vary " exists. On the other hand change in the former, if uncompensated, must as certainly induce change in the latter. The induction is not complete, as no induc- tion ever can be, but the number of instances is already so great and so rapidly increasing that the conclusion cannot be called premature, and while every day increases its probability. It is true that we cannot as yet show many examples of invariance through very long periods of time. Species die out and others come in. Change is the rule, and we have so far found few exceptions. But the biologist does not stand alone in thus advancing a step beyond the cover of "bald facts." Other students in other departments are accustomed to do the same, and boldly to accept the logical outcome of their observations even in cases where for want of opportunity the crucial experiment can- not be performed. A mechanical illustration will make the meaning clear. The first law of motion is thus expressed by mechanicians: "A body continues in a state of rest or of uniform rectilinear motion unless acted on by some outside force. ' ' Yet the mechanician has never seen "a body in a state of rest or of uniform rectilinear motion." His faith is nevertheless unshaken. He argues that as every approximation to the necessary conditions is followed by a nearer approach to such motion if he could obtain perfect conditions, perfectly uniform rectilinear motion would result. The force and justice of his argument are admitted. And on proof like this he builds his science of mechanics, and on this science the works of the engineer confidently rest. PKOC. AMER. PHILOS. SOC. XXIV. 125. Q. PRINTED MAY 21, 1887. Claypole.] 130 [^^pHl 1, Now conceive an organism as tlie moving body, tlie motion of the latter being represented by the specific life of the former. As the moving body travels through space, so the organism travels thi-ough time. If unaf- fected by outside disturbing force the former continues in a straight line. So if unaffected by changes in its environment, the latter remains unva- ried from generation to generation, merely changing its position in time as the former in space. Thus each would continue indefinitely, the same in all respects except position, after many thousand years had passed away. But on its way the flying body approaches some other mass of matter, and immediately feels an influence by which its own motion is modified. So on its way through time the organism comes into a different environ- ment to the influence of which it responds by modification of structure or habits or both. These modifications are the necessary consequences of the changes in its surroundings. In the former case we call them physical, in the latter natural. Hut in neither do we know anything of the mode of working. Of the "why" and the "wherefore" of both we are equally ignorant. The mechanician sometimes imagines that by attributing the one to " universal gravitation " he has explained it. But he has not. He knows nothing of the nature or of the cause of this universal gravitation. The biologist is not yet sufficiently advanced to generalize variation and give a definite name to its cause. But with this unimportant difference the two are in the same predicament. The parallel may be followed a step farther. The body moving through space and the organism through time are alike in another respect. The former maj^ be drawn forward and its motion accelerated by an outside force. So the latter may vary and improve under the influence of envi- ronment. The former may be retarded and its motion may be diminished or destroyed. So by unfavorable environment the latter may vary in a prejudicial manner until extinction ensues. Yet again the for- mer may, under the influence of the disturbing forces, change its direction without either acceleration or retardation. So the latter may vary in directions which shall be perfectly neutral in their effect upon its welfare, and the new form may be as capable of survival as the old. In both cases the variable is perfectly passive and plastic in the hands of its environ- ment, and the environment is perfectly indifferent to the welfare of the variably. The ensuing variate is an outcome of the conditions of the world around it and must take its chance among them, living if in har- mony, or dying if in discord. In both the above cases the crucial experiment is beyond our reach. To obtain absolutely uniform rectilinear motion there must be only one body in the universe, and no resisting medium. To obtain an absolutely unchanging variable organism there must be no alteration of the condi- tions of existence. Both are alike unattainable. Yet, as with the mechani- cian so with the biologist, every approximation brings him nearer to the desired result. The vertebrates are least capable of enduring changes of environment, and land surfaces afford the most variable conditions of life. 1887.] ^'^^ [Claypole. Among the vertebrates, therefore, of a terrestrial fauna occurs the most rapid evolution of animal forms. The depths of the sea are the places where conditions vary most slowly. The lowest forms of animal life are least affected by changes of environment. Accordingly among low forms of life, and at the sea-bottom, we find most persistence of type. Illustra- tions might readily be quoted, but they are needless. The facts are famil- iar to every naturalist. And reasoning from these facts in the same man- ner as does the mechanician the biologist argues. that could he obtain the requisite unchanging conditions his species would continue unvarying for an indefiaite time. Though still variable they would be perfectly inva- riant. VIII. Nature's "Waste of Variates. Nature's variates thus produced talve their place among their physical and organic surroundings. With these they are more or less in harmony and in discord. If they can, they live ; if not, they die. Nature has no care for her nurselings. She casts them adrift on the world to shift for themselves ; to swim if they can ; to sinli if they cannot. She neither aids nor hinders them. She "cares for nothing." It is a game of "hit or miss ;" a method of " trial and error."* If a somewhat homely simile may be here allowed I will lilien the process of Nature in producing variates that are in harmony with their environ- ment to the plans adopted by large commercial houses in making their goods known. Not knowing where their customers can be found they scatter advertisements wholesale over the country. Here we find the name of the firm in a newspaper, there at a railway station, here in a magazine, there on a blank wall, here on the fly-leaf of a book, there on the back of a railway ticket, in one place on the pavement underfoot, in another on the ceiling overhead, now on a handbill forced on us in the street, then around the pages of a railroad guidebook, and some- times even on the fences and the rocks in little frequented spots. Every- where crops out evidence of a systematic effort to catch the eye of the public by dint of irrepressible advertising without definite method. Of all these attempts the greater part are doomed to failure. Overlooked by the eager readers of the news-sheet and of the railway guide, trampled under foot by the hasty passenger in the street, read and immediately forgotten by the preoccupied and the thoughtless, they live out their little lives as variates among uncongenial conditions, as seed in stony ground, and pass * It is to this neglect of her variates that the slowness of Nature's results are due com- pared with the rapidity with which varieties are obtained by man. A valuable seedling grows up in some out of the way place ; man secures it, propagates from it and so per- petuates the variate. But if left to Nature it is probably destroyed and the opportunity lost. Every variety and, still more, every species of Nature's making may fairly be looked on as the result of many experiments undertaken and brought to the verge of success only to be abandoned and fail. Claypole.] J-^-^ [April 1, away without remembrauce or result. But here and there one out of the great number catches the eye of some one in want of the thing adver- tised. It brings him in as a purchaser and a sale is made. One success out of a myriad of failures. Yet the purpose is served and the business maintained. So with nature. She launches into the world her countless hosts of vari- ates — in form, in color, in size, in strength, in bodily and mental qualities. Of these, myriads — perhaps the great majority — die and leave no trace. But here and there an individual possessing characters more in harmony with its environment than those of its ancestors or relations takes advant- age of the fact, increases rapidly and finally in the struggle vanquishes them and takes their place. The old organism yields and the variate is called the new species. Such is the method of trial and error employed in Nature if we judge impartially from the facts that meet our eye in every field of the organic world. Strictly speaking every individual is a variate, for never does the oflF- spring in all minute points resemble its parents. But when out of these hosts of variates all the unfit have been eliminated how few remain. How few even among the human family live to manhood, and how much smaller is the number among the wild species. Nature appears to keep in her workshop moulds of almost every conceivable form, and in these moulds she casts her variates, issuing them broadcast on the world in order to see which can survive. The greater number perish. Only here and there does one prove to be in harmony with its environment and live. But those that perish are quickly destroyed and forgotten — melted down and recast — while the survivors apparently testify by their fitness in favor of special adaptation. IX. Creation bv Beneficial Variation and by Special Design. In this prodigal waste of her variates therefore rather than in their eco- nomical production by beneficent variation, we find the clue to Nature's method of creation. She does not make a new variate in perfect harmony with its surroundings and then carefully watch and nurse it into growth and supremacy. She does not study the surroundings in order to make the variate. Still less does she fashion the surroundings to fit the variate. On the contrary her plan is to produce her organisms in vast numbers, and of varied forms and leave them to be assorted by the sifting process of natural selection. The unfit many soon perish. The fit few alone survive and multiply. The result is that nearly all living species thus sifted out are in a harmony so nearly complete with their environment that it seems at first view intentional. And this is the fallacy underlying the argument of the teleologist, whether he belong to the school of "beneficial variation," represented by the writers quoted at the outset of this paper, or to that older school that formerly pressed and whose adherents still press, though 1887.] lod [Claypole. with somewhat diminished confidence, the famous arguments for "creation by special design." These writers maintain that the adaptation of an organism to its sur- roundings is a proof of a specially designing intelligence. They say that the countless instances of accommodation discoverable in existing nature and those which may be inferred in past ages could not have come to pass except by intent. It is needless to quote examples. They are familiar to everybody. They have been enlarged on from the daj^s of Paley's watch picked up on a common down to the present day. And even now books issue from the press reasserting and attempting to reinforce this old argu- ment. Yet from the point of view here taken this "argument from de- sign " is entirely illusory and obtains all its apparent importance and its seeming strength from being based on a mere partial view of the subject. The teleologist picks out instances of organisms that are in harmony with their surroundings, sees and studies the many and minute adaptations of the one to the other, and then somewhat hastily infers a special intention in the arrangement. From the examination of a few instances he infers a general rule and asserts that every organism is specially adapted to its en- vironment by intelligence. The inference is natural, obvious and pardon- able on a superficial view, but wider and closer observation refutes it. Every organism is in approximate harmony with its surroundings because, as said above, it lives only on that condition. If not it dies. This fact the teleologist fails to see or to appreciate. By him the constant struggle for existence is unseen, the cries of the vanquished are unheard, the thousands that are born only to die of unfitness are unnoticed. Were all these ele- ments taken into account his problem would be less simple and his re- sults less easily reached and less confidently announced. Special inten- tion or design in creation could hardly be affirmed of a world where the greater part of the experiments fail of success. Returning for a moment to the illustration employed above, the tele- ologist is in the position of one who seeing an advertisement fall into the hands of a man in need of the article advertised should straightway infer a special design in the advertiser to bring these two together. Not seeing or not heeding the thousands that went to waste he comes to a hasty and incorrect conclusion by imperfect induction. A wider view would give a juster sense of the relation between the failures and the successes and enable him to see the design, for such it may fairly be called in its true light. For, be it understood that evolution as here defined by no means dis- proves design. To assert or to imply this would be as illogical as the fault just condemned, but in the opposite direction. That it disproves " special design " is, it appears to me, evident. But design of another kind and of a wider scope, working in quite another fashion — " the method of trial and error" — may yet exist behind all. On this question evolution thus far speaks doubtfully and the biologist holds no positive opinion. Of one fact, however, he is confident — that all the changes of organic Oaypole.] 1«^4 [April 1, life are results of unswerving "natural law," the details and modes of •whose working he cannot yet trace. Chance at present seems supreme among the tranformations which evolution has revealed. But chance is only a name under which we disguise our ignorance. In a world under the action of universal natural law. Chance, that is, causeless effect, can- not exist. Chance in this sense is to the careful student of Nature un- thinkable, inconceivable. Every event is a consequent of antecedents and an antecedent of consequents. Order, such as it is, prevails everywhere. The sequence is unbroken. Every existing species is a single link of a chain, one end of which is lost in the distant past and the other end has not yet emerged from the distant future. Every link depends from that preceding it and serves as a point of attachment for that which follows. What the one is the other will be, barring the effect of outside inlluences, and could the exact nature of the organism be known and the exact effect of environment be determined, it would be possible to foretell the exact nature of the ensuing variate. But firm as is the faith of the biologist in the existence and ceaseless action of universal law he admits his utter ignorance of that deeper force or of those deeper forces that keep the law in action. This must be determined from the working of the law itself. He must reason back from the law ta the underlying principle and determine the nature of the latter from the mode of the former. And if in this profound investigation he finds him- self coming to results which clash with prevalent or preconceived opinion, if the law ofthe universe seems other and harder than poets have feigned, yet sentiment and prejudice should not be allowed to lie as stumbling-blocks in the path of advancing knowledge, nor should the faint voices and dim lights which come to us out of the darkness ahead be disregarded, though they would lead us in different direction from that in which we were wont and wishing to go. COXCLUSIOX. A possibility looms up before the biologist on this view of his science which no other theory can encourage. If all organic changes come about as consequences of changes of environment, why should it be beyond rea- sonable hope that he may some day be able to grasp the effects of the lat- ter so completely as to foretell the former? Astronomy was once in the state of confusion and ignorance in which biology now lies. The move- ments of the planets were an unsolved enigma, their paths a tangled maze, their mutual influences a seemingly hopeless chaos. But Copernicus, Kepler, Galileo, Xewton, Laplace and Leibnitz arose. The kev of the enigma was found, the clue to the maze, the order in the chaos. And now of all the physical sciences, astronomy is the most exact, the most thor- oughly under control of mathematical laws. The astronomer, rising above the task of merely recording the past, predicts the future. The movements of the planets are understood ; universal gravitation enables him to grasp them, and the subtle mathematical analysis gives him the 1887.] 1^5 [Claypole. means of seizing any one of them, of tracking it through space, of mark- ing its course, of including the varjing effects of other globes, and finally, from his complicated formula, he educes a prediction of its place at any moment in the future. Is it too much to hope that some day the biologist too will rise to the same position ; that some other and greater Darwin will be born to give us a generalized law of variation ; that some biological Newton will arise and enable us to compute the complicated problem which organic beings present in passiog through their different stages of variation ? If even now the pigeon-fancier will undertake to produce in a given time a bird with any desired plumage (within possible limits) ; if the cattle-breeder can call into being a variety retaining desirable and excluding undesirable qualities ; if a gardener can develop a new and valuable variety of plant, and fix its characters so that it comes true from seed for many years, why should we not hope that some day the special will become the general, and that what can now be done in a few cases will then be done in all at will? When the effects of changes in the environment are definitely known and traced back to their special causes, their direction and amount determined and their condition so fully understood that they can be repro- duced at pleasure, then will the material be in our hands for the final gen- eralization. Is it too sanguine to hope that a biological analysis will then be invented and perfected as mathematical analysis has been perfected, and that the biologist, armed with this new engine of investigation, will 'be able to trace the past evolution of organisms to its causes in the organic world? And, bolder still, may he not venture into the future, seize in the grasp of his Calculus any variable organism, and involving in his formula the successive conditions of its environment, trace it through its compli- cated changes during its period of variance until his equation yields up the function — the variate — at the end of any desired inj,erval, exhibiting new characters and forming a new species ? Is such a prospect, though distant, altogether visionary ? May we not hope some day to solve the great evolutionary problem ? Given, a vari- able organism and the conditions of its environment during a certain time, to determine the consequent changes. Mooney.] ^'^^ [April 15, THE MEDICAL MYTHOLOGY OF IRELAND. , By James Mooney, Washington, D. C. {Bead before tlie American Philosophical Society, April 15, 1887.) Note.— The information contained in the following paper has Deen obtained by the writer's personal investigation among the people who believe and practice the things described, and has not been obtained from books, although numerous works bearing on the subject have been consulted. Every belief and custom described is still in vogue in some part of Ireland, especially in the west. They have even been transplanted to this country, and some of the charms mentioned have been used by Irish men and women for the relief of children at the request of tairly intelligent American parents, while the accidental death of a young man at Holyoke, Mass., some years ago, is attributed ))y his friends to the evil eye of a Mearnan who was near him at the time. Where inquiry among people of diflFerent sections has shown a custom to be general, the lact has been stated, and most of the charms described as local would prob- ably prove to be generally known on further investigation. — The Author. For several reasons the mytbologic theory of disease has probably reached its highest development and retained most of its original strength among the people of Ireland. Her national life was crushed into the ground by an alien tyrant while still the gloom of the Dark Ages hovered over Europe, and when the Irish nation itself had hardly emerged from the tribal condition. The island which had been the home and the refuge of scholars during the troubled centuries which followed the fall of the Roman empire was given over to desolation, and the fire kindled upon the altar of learning went out in blood and tears. Laws were enacted against the dress, the language, the very names of the people, and it was held no crime to kill an Irishman. Schools and monasteries were despoiled and their inmates hunted down like wild beasts or banished from the country — the same price was offered for the head of a priest and for the head ot a wolf — and for nearly seven hundred years teaching was a trea- son and education a crime. When at last, within the present century, the laws became at least human, and schools were established throughout the country, the same landlord system against which tlie Irish people are now fighting fastened them down with a weight of poverty which their utmost exertions were not sufficient to throw off. The people had no time or money to go to school, and therefore remained in a great measure uned- ucated. In addition to all this must be considered the peculiarly spiritual temper of the Kelt, and especially of the Gael, which inclines him to a strong faith in the things of the invisible world, and renders the Irish nation an eminently religious people. The same qualities, when not properly directed by education, lead naturally to superstition, the religion of ignorance. If a line three hundred miles long be drawn through the greatest extent of the island, from Inishowen in the north to Cape Clear in the south, it will divide the country into two parts, of nearly equal size. The eastern 1887.1 [Moouey. section is a fertile plain, shut in by low mountains along the coast, and being naturally easy of access and more exposed to foreign influence and colonization, its inhabitants have lost much of their original character and nearly all of their language. The western section is chiefly a region of rugged mountains, and limestone clifts covered with a thin layer of soil, where no one but an Irishman would attempt to raise a crop. Its inhab- itants, who are fishermen on the coast and shepherds in the mountains, are still in the primitive condition of their ancestors, retaining in a great degree their simple habits and their Gaelic language. The typical districts of this region are Donegal in the north, Kerry in the south, and Conna- mara in the extreme west. Here the practices and beliefs which were once general throughout the country still have full sway, the enchanted horse dwells in the lough, and the fairies dance under the hawthorn. The Practitioners. In describing these customs and beliefs they will be treated, not as half- forgotten superstitions raked up out of the past, but as living realities, for such they are in fact. The medical professors of this region are generally old women, whose stock in trade consists of a few herbs and simple decoc- tions, a number of prayers and secret formulas to be recited while apply- ing the remedy, and a great deal of mystery. Such a woman is com- monly called a cailleac luib'e- "herb hag" or beanfeasac'f "knowing woman. " When her art is of that doubtful kind which tends rather more to the injury than to the good of her neighbors, she is called a piseogX and the same name is also applied to her nostrums. In some few cases the doctor is a man. There are also a number of persons who have cures for particular diseases, these cures being innate in the individual, owing to some accident of birth, or hereditary and transmitted from parent to child from a remote generation. When hereditary, the secret is jealously guarded — even by the mother from her child — and only revealed upon the deathbed, to some one of the family who, at the same time, is pledged to silence. For this reason it is almost impossible to get the formulas used with any of these cures, but there are a number of charms in use which are common property, and from a knowledge of these the character of the others may be guessed. In rare instances the possessor of a cure bestows it upon another in return for some favor, the charm losing none of its efficacy by the transfer. It is generally considered essential that the charm should have been inherited from a woman by a man, or from a man by a woman. Persons who possess these single cures give their services * Pronounced cawl-yakh ttva. The Connamara i)ronuuciation is given, unless other- wise noted.

The other class, on the contrary, who are considered as akin to dealers in the black art, act upon the principle of "nothing for nothing." In Connamara it is customary to cross their hand with a two shilling piece, a silver coin having a cross upon one side, the sacred emblem being supposed to compel them to speak the truth. The herbs are gathered fasting, generally by moonlight, and whisky enters largely into the decoctions. These practitioners have their specialties, and one who deals with the evil eye will have nothing to do with a fairy sickness, neither will the "fairy woman " meddle with an illness which is due to the influence of the evil eye. It must not be supposed, however, that the people depend entirely upon the skill of these doctors. On the contrary, every house- keeper is well acquainted with the virtues of all the common herbs, to which she never fails to resort in case of need — always accompanying the application with a prayer — and it is only when she has exhausted her resources or is convinced that the sickness is of supernatural origin, that she applies to the cailleac luib'e. When an ailment does not yield readily to simple treatment, it is generally ascribed to one of three causes, viz., the fairies, thfe evil eye, or witchcraft. The last of these is not often held responsible, as Irish witches usually confine their operations to stealing the butter, and seldom harm the owners. We will speak first of the fairies. The Sig'efkeog and Fairy Influence. The person, of either sex, who treats illness of fairy origin is called a sig'efreog,* the name being probably a diminutive of sig-efear,\ a "fairy man." In the south they are called sheefers or sJieefros, while in the east they are known as fairy men or women, as the case may be. They have generally obtained their knowledge by a residence of some years with the fairies, who frequently carry off both grown persons and infants, and detain them for three, five or seven years, unless forced to return them sooner. Young mothers and their infants are especially liable to be abducted, and to prevent such a calamity numerous precautions are adopted, which need not be described here. The health — at least of grown persons — is in noway affected by their sojourn among the fairies, while they learn all the secrets of their captors and afterward use this knowl- edge to defeat their purposes. Although, after returning to their friends, their services are in constant demand to counteract the fairy influence, they are never able to shake it off" from themselves, but are frequently called away, even in the dead of night or from the midst of a company, to perform some office for the " good people " — generally to wait upon a fairy mother or her child. The fairies naturally resent the interference of ■ • Pronounced sheefroeg. t Pronounced shee-fCir. 1887.] i-OtJ TMoonev. the sig'efreog, and while gatliering her medicinal herbs she is frequently stricken with convulsions and falls to the ground, foaming at the mouth, owing to the violence of her struggles with the invisible beings, who strive to tear the plants from her grasp. In one instance, in the County Clare, they seized a man at night in a lonely place, and beat him so terribly that he was confined to his bed for a week afterward. In addition toher medical knowledge, the sig-efreog can read the thoughts of others, and tell the whereabouts of missing articles, and her powers are often inherited by any of her children who may be born after her return from fairy land. She also warns the people occasionally against doing anything which would incur the ill will of the fairies, such as throwing out dirty water after nightfall, when the elves are engaged at their sports ; forgetting to leave clean water on the dresser for them to drink ; or saying grace over the potatoes without first setting aside a portion for the fairies, who cannot touch consecrated food. Such is the dread of ofiending these spirits that they are seldom mentioned under their true name of sig'e,* or "fairy," but are generally called daoino mat'a,\ or "good people," fre- quently accompanied by the invocation, Fogramuid deag'-c'om'arsanac't oraib',X "we beg good neighborship of you." The supernatural power of the sig'efreog is sometimes due to some remarkable cause other than a residence with the fairies. In the County Clare is a wild mountain lake known as Lough Doon, where St. Patrick confined the last of the serpents, which still at rare intervals comes out upon the bank. On one of these occasions the serpent was seen by a man who ever afterward "had a cure." There formerly lived near Tuam, in the County Galway, a cripple known as Dom'nal Crom,% or "Crooked Daniel," who, on account of his infirmity, was generally appointed to watch his neighbors' cattle upon the mountain side. While thus engaged one day he saw a bull descend from the heavens and associate with one of the cows. By drinking the first milk drawn from the cow after the birth of the calf he was endowed with a knowledge of fairy doings and the gift of prophecy. 11 A single instance, from east Galway, will serve to illustrate the man)ier of fairy seizure and rescue. A woman was carried off while her husband was out of the house for a short time, and on his return, instead of the blooming young wife he had loved, he found a shriveled whimpering creature, who would take no care of the child. He was in great trouble over the matter for some time, until one night, as he was coming across * Pronounced she. t Pronounced dheence moha. t Pronounced FoegramHj jaw-khoersancikhth tiriv. § Pronounced Dhonaid Cnim. 11 This man is referred to on page 83 of Sir Wm.

Mooney.] XtlU [April 15, the field, he saw his wife standing in the Jmggart* Going up to her, he asked her, in the name of the Trinity, who had her in their power, and what he must do to rescue her. She told him that she was with the fairies and that there was one way by which he could recover her, if he had suflicient courage to try it. On a certain night and at a certain hour, a company of mounted fairies, with her in their midst, would enter a fairy fortt near his house. He must be ready with some urine and some chicken dung, which he must throw upon her and then seize her. He promised to do as directed, and at the appointed time he was in waiting near the fort. Soon he heard the fairies approaching, and when the noise came in front of him he threw the dung and urine in the direction of the sound, and saw his wife fall from her horse. He seized her, and although the fairies crowded around and strove to tear her away from him, he defied them and held on to her until they gave up the attempt and retired into the fort, when he brought her home with him. At the instant he seized her there came such a blast that "you'd think the wind would sweep the roof from the house," and in the midst of it all the withered hag disap- peared and was not seen afterward. The woman lived to a good age and had several children after her return. The method adopted in this case to break the power of the enchantment is especially to be noted, as it is a cardinal principle in Irish mythology that fairies, being pure spirits, cannot endure defilement. Even a hand- ful of dust thrown into their midst will sometimes cause them to release their hold on a prisoner. The same ingredients enter into most of the charms and amulets used as a protection against the fairies. The chicken, also, is regarded as peculiarly sacred, and some wonderful virtue is con- nected with everything belonging to it. According to popular belief, the fairies can take anything but a chicken or an egg. Unusually promising young children — especially infants not yet bap- tized^-are frequently carried off by the fairies, who leave instead what are known to be changelings by their pinched and withered features, their hollow voice, their constant crying and inordinate appetite, and their unnaturally shrewd remarks and actions. In other words, the uninformed observer might think them precocious children in delicate health. In such cases, when there is no longer any doubt in the matter — for mothers are always slow to be convinced of the real truth — the fairy woman is called in to bring back the stolen child. Her usual method is to heat the shovel in the fire, place the changeling upon it and put it out upon the dunghill. She then returns to the house and recites certain words, after which the family go out to the dunghill and find there the real child, in place of the other, which has been taken away again by the fairies. The child seldom * An outdoor inclosurc for storing grain and hay. t Prehistoric circular earthworks, with underground passages, very numerous tliroughout tlie south and west, and popularly believed to be the abode of the fairies.

In this operation we have a combination of fire, iron and dung, the three great safeguards against the influence of fairies and the infernal spirits. Three is also the sacred number in Ireland, as well as throughout Europe. The changeling sometimes leaps through the window at sight of the prepa- rations, and disappears in some unaccountable manner, when the real child is found asleep in the cradle. This method is known throughout the coun- try, but there are also other ways to accomplish the same purpose. In the County Cork the mother, while still fasting, takes the changeling before sunrise to a point where three running streams meet, and after stripping it, dips it into the water three times in the name of the Trinity. This is done on three successive mornings, and on returning home the third morning her real child is restored to her arms as she enters the doorway, the substitution being effected instantaneously by the fairies. In another instance a young man was suddenly stricken with a rheu- matic illness, which confined him to his bed nearly three years. At last one day while his parents were gone to the market he got up and joined the younger children playing outside the house, and was as active as any of them. When it was about time for the parents to return he went back to bed again. The children told the old folks all about it and an elder brother agreed to watch the next day. In the morning the parents started off again, but were hardly out of sight when the sick man was out of bed once more and in the field with the children. The watcher ran toward the house to see if the bed was empty, but with all his swiftness, the rheu- matic got there first and was in bed when he entered the door. The brother look up an ax, and approaching the sick man, swore that he would kill him if he did not tell who he was. "Oh, brother," cried the sick man, "don't strike me, for I have only a few more days to serve, and then I will be with you again." The brother desisted and soon after the young man was restored as well and strong as he was three years before. He explained that a servant girl of the family, who had apparently died about a year before the beginning of his illness, was with the fairies, and had warned him not to accept food or drink at their hands. He followed her advice, and at the end of three years, the shortest period of fairy de- tention, they were consequently obliged to release him, while the girl who had made the fatal mistake of eating with them was never restored. The young man was the son of a respectable farmer named Halpine, in the County Limerick. This belief in the presence of a fairy changeling in .place of the sick person is very general, especially in the case of infants which pine away without apparent cause, strong young men suddenly stricken down, and old persons whose illness is of a fitful and lingering nature. It probably has its origin in the change in disposition and features under such circum- stances, and the unwillingness of the people to believe that this can be Moouey.] i-±— [April 15, the result of natural causes. The supposed fairy is sometimes threatened to force him to reveal his identity, and when the case is evidently hope- less, although the patient still lingers, a piece of Lus-Mor* or foxglove, is put under his bed. If he be a changeling, the fairies will be compelled to restore, at once and in good health, the person taken away. If the in- valid be really present in his proper person, he will not recover, but die. The reason of this is, that when the soul, after death, is brought up for judgment, it is sometimes condemned to return and re-animate the body, and endure with it all the miseries of sickness until its sins have been ex- piated, when it is finally separated from the flesh and enters into eternal happiness. The fairies take advantage of this temporary absence of the soul before the judgment bar to put one of their number into the body so that when the soul returns it finds its place occupied and is obliged to go with them. The presence of the lus-mor compels the fairies to take away their spirit from the body and release the soul, which then enters at once into glory. This, of course, i^no part of the Catholic belief, but a survi- val of the old paganism. Lameness is frequently the result of having intruded upon the precincts of the fairies or interfered with them in some other way. For this reason the people are especially careful not to disturb the fairy forts or venture near them after nightfall. A girl near Feakle, in the County Clare, fell asleep in a fort on a harvest day, and on awaking in the morning found herself unable to walk on account of a painful ulcer on her limb. The fairies had struck her for coming upon their ground. After a long illness something like a thread of flax came out of the wound and she recovered. Ulcers, scrofula and running sores are commonly called " fairy strokes," and attributed to fairy influence. The particles of hardened pus which sometimes come out of the sore are the fairy darts which have caused the wound. A man near Dunmore, in Galway, rented a small farm upon which was a fairy fort, which was overgrown with bushes. As these were never disturbed they at last began to encroach upon the cultivated ground. In spite of the remonstrances of his wife he determined to root out some of them, but had hardly begun the work when he was struck with such a sharp pain in his leg that he fell to the ground and had to be carried into the house and put to bed. His wife went out and replanted the bushes just as they were before, when he at once got relief. This was told bj-- the man himself and confirmed by his wife, who was present and added : "If there is one thing certain, it is that there are fairies in Ireland." He holds a responsible position at a salary of 81300 per year. Near Bandon, in the County Cork, lived a man who in his youth was a noted jumper, and on cue occasion leaped across a ditch twenty-two feet in width and alighted in such a manner as to severely injure his foot. A running sore appeared on his ankle and pieces of bone came out. His mother procured from a fairy woman a "bottle of herbs," which was rubbed upon the foot and ♦Pronounced lus-more; literally the "great herb." 1887.] 14d [Mooney. resulted in a cure. The bottle -was paid for with a basket of eggs, each one of which was marked with a black cross made with the burned end of a stick, probably of furze. Tlie woman explained that he had been kicked by the fairies, who were passing that way when he jumped into their midst. This woman went every night with the fairies, who sum- moned her with a peculiar whistle, which was heard by other persons as well as herself. She was once called away from a wake in this manner, but no one had the courage to follow her. The story is given as told by the man who made the leap, an old soldier who has spent the last tliirty years fighting Indians and border outlaws on the frontier, and is now laid up for repairs at the soldiers' home near Washington. When a boy he often watched all day at the entrance to a fairy fort to catch a glimpse of the fairy shoemaker, but he says he no longer believes in such things. Another of these women kept a bottle of water, and by holding it up to the light could tell whether or not a sick person would recover. A man once came to her to inquire about his brother, who was sick. She looked at the bottle of water and said, " You have come three minutes too late." The man went home and his brother died. When any one sneezes, it is in consequence of a blast from the fairies, who are then endeavoring to carry him off. At the third sneeze they will accomplish their object, and leave a corpse or an invalid changeling in his place, unless some one present exclaims, "God bless us!" On hear- ing the name of God the fairies take flight, and it is hardly too much to say that this ejaculation is never omitted on such occasions. A similar custom prevails throughout Europe and has been traced back as far at least as the time of Homer. The prehistoric stone arrow head, or saige'ad* occasionally found in the country, is a fairy dart which has been shot at some man or animal, and thus lost. The fortunate finder can counteract the designs of the fairies, and the old woman who possesses one is regarded with much veneration, and in the expressive language of the people, "she will get good nursing." When an illness is supposed to be due to the influence of the fairies, the saig'ead is put into a tumbler and covered with water, which the patient then drinks, and if the fairies are responsible for his sickness he at once recovers. The saig'ead is preserved in some iron receptacle to prevent the fairies stealing it. As so many physical evils are due to the fairies, it is natural that some means should be used to ward oft their influence. For this purpose a horse shoe is nailed over the door, while garlic is planted in the thatch above it. As newly made brides and young mothers are in most danger from this source, a great many measures — which come more properly under the head of marriage customs — are taken to prevent the abduction of either the wife or the child. It may be in order here to state that no fire must be taken out of a house while a woman is sick within it, and * Pronounced siedh, equivalent to the Latin sagitta. Mooney.] ■'■'*4 [April 15, there is a general reluctance to lending anything whatever out of the house at such times. The ancient religion of Ireland was Are worship, and numerous vestiges of the old belief still exist among the popular cus- toms. Scraps of iron are frequently carried as a protection against the fairies, and in Connamara it is still a common practice to wear about the person what is exactly equivalent to the medicine-bag of the Indian. The con- tents of this bag, which is about the size of a liiclvory nut, are known only to the owner, who conceals also the fact of its possession even from his most intimate friend, but among them are usually found tobacco, garlic, salt, chicken dung, lus-crea, and some dust from the roadside. This is worn also as a protection against the evil eye, and something of the same nature is sewed into the clothing of the bride when her friends are pre- paring her for the marriage ceremony. Convulsions in a child are sometimes due to the influence of the fairies, being probably the result of its struggles to escape from their grasp. The theory and practice are best illustrated by relating an instance, which is given just as it was told by the narrator, who knew the mother and believed the story. A woman had a child which was subject to danger- ous convulsions, and after one unusually violent attack she consulted a fairy woman, who told her what she must do. On her way home the mother picked up from the roadside ten small white pebbles known as fairy stones. On reaching home she put nine of these into a vessel of urine and threw the tenth into the fire. She also put into the vessel some chicken dung and three sprigs of a plant (probably garlic or ivy) which grew on the roof above the door. She then stripped the child and threw into the fire its shirt and the other garments which were worn next the skin. The child was then washed from head to foot in the liquid, wrapped in a blanket and put to bed. There were nine hens and a rooster on the rafters over the door. In a short time the child had a violent fit and the nine hens dropped dead upon the floor. The rooster jumped down from his perch, crew three times, and then flew up again to the rafters. If the woman had put the tenth stone with the others, he would have dropped dead with the hens. The child was cured. Vicarious Cures. This single instance combines in itself a numberof important features in connection with the popular mythology— the dung, the urine, the plant over the door, the chicken, the fire and the garment worn next the skin — and introduces also a new element in the popular theory of disease, viz. : the idea of vicarious cure, or rather, of vicarious sacrifice. This belief, which is general, is that no one can be cured of a dangerous illness unless, as the people express it, "something is left in his place," to suffer the sickness and death. A few illustrations from the County Clare will exem- plify this belief. 1887.1 • 14o [Mooney. A father, whose son was nearly at the point of death, applied to a man noted for his healing powers, who told him that the boy could be saved but that something must go in his place. " Well," said the father, "take anything that I have but a Christian." The other said it would not do for him to accept anything, but that he would put his own horse in the place of the boy. He then told the father to watch the horse, which was just coming up from the sea with a load of sand. The moment the carl reached the spot where the sand was to be put, the horse dropped dead. When the man arrived at home his son was well. In another instance a woman was sick, and her husband called in a man who told him to take every living thing out of the house before he pro- ceeded to cure her. The husband put his cliildren out of the house, but forgot "a sow with a litter of bonnivis"* in one corner. The other man then recited certain prayers and restored the woman to health, but when the family came back again into the house they found the sow and the bonnivs dead. At another time a man's wife was sick and the operator was sent for. He recited some words and the woman began to recover, but the next morning a fine cow belonging to her husband was found lying in the field, groaning and unable to rise. The cow grew worse as the woman grew better, and when the cow died the woman was well. In the same connection may be mentioned a custom which prevails among the fishermen of Mayo and Connamara. Every master of a fish- ing boat carries a dog with him when out at sea, and should a storm arise, the dog's legs are tied together and it is thrown overboard, in the belief that the sea will at once become calm. This practice e.xists in Ireland to-day, in the nineteenth century, and is exactly what formerly existed among the Indians on the great lakes, as we learn from the trader, Alexander Henry. In 1766, while crossing Lake Huron in a canoe with a party of Ojibwas, a storm came up, which was attributed by the Indians to the anger of the snake god, whom he had oflended the day before by attempting to kill a rattlesnake. After calling on the snake god for help, " One of the chiefs took a dog, and after tying its four legs together threw it overboard, at the same time calling on the snake to preserve us from being drowned, and desiring him to satisfy his hunger with the carcass of the dog."f We read in the Bible how, nearly three thousand years ago, the prophet Jonah, fleeing from the will of God, was on board a ship in the 3Iediter- ranean when they were overtaken by a storm. After calling upon their several gods, and using every effort to right the vessel, the sailors cast lots to discover who was responsible for the storm, and the lot fell upon the . prophet. " Then said they unto him. What shall we do unto thee, that the sea may be calm unto us? for the sea wrought and was tempestuous. And he said unto them, Take me up and cast me forth into the sea ; so * Gaelic, banab', a sucking pig. t Henry, Travels, 178, 1809. PROC. AMER. PHILOS. SOC. XXIV. 125. S. PRINTED JUNE 4, 1887. Mooney.] i4b [April 15, shall the sea be calm unto you, for I know that for my sake this great tempest is upon you. * * * So they took up Jonah and cast him forth into the sea, and the sea ceased from her raging" (Jonah, i : 11, 12, 15). Another belief, which exists alike in Ireland and among the Indians, is that certain localities are the abode of invisible malignant spirits, which visit sickness and death upon those who come within their reach. These evil spirits are overhead in the air, and are quite a different order of be- ings from the fairies, who live upon or under the ground, and on the whole are rather regarded as benevolent. If sickness or death occurs in a new house, it is frequently ascribed to this cause, and the house will be removed, or torn down and rebuilt in another place. There is also a way by which the pains of maternity can be transferred from the woman to her husband. This secret is so jealously guarded that a correspondent in the west of Ireland, who had been asked to investigate the matter, was at last obliged to report : " In regard to putting the sick- ness on the father of a child, that is a well-known thing in this country, but after making every inquiry I could not make out how it is done. It is strictly private." It came out, however, in a chance conversation with a woman who, when a child, had once been selected to wait upon a nurse on such an occasion. At a critical moment the nurse "hunted her out of the room," and then, taking the husband's vest, she put it upon the sick woman. The child had hid behind the door in the next room and saw the whole operation, but was too far .off to hear the words which were probably repeated at the same time. It is asserted by some that the hus- band's consent must first be obtained, but the general opinion is that he feels all the pain, and even cries out with the agony, without being aware of the cause. The Evil Eye. The belief in the existence of the evil eye is general throughout Ireland as well as throughout the greater portion of Europe and Asia. It was held also by the ancients, among whom there were whole nations whose glances were supposed to be fatal, and it was even thought that there was death in the sound of their voices. The eastern nations, both Christian and Mohammedan, ascribe almost every unaccountable illness to this cause ; and among the Turks sentences from the Koran are written upon the walls of the houses to counteract it, while glass balls are hung from the ceiling, and gaudy trappings put upon the horses, to divert from the owner the attention of the evil-minded beholder. So general is this be- lief that a writer upon the subject says : "It is not improbable that if the matter were still more profoundly investigated, it would be found that every nation that exists, or has existed, with anything like a developed system of superstition, believes or has believed in the reality of fiiscina- tion in some form or other."* There seems to be nothing exactly simi- lar among the Indians, at least among the Siouau tribes of the plains, *Am. Cy.,iv, 177,1880. 1887.] ^^* [Mooney. although the belief is said to exist among some Californian tribes. It may be that the idea is too subtle and intangible for the mind of a savage. The general prevalence of this belief would seem to indicate that there must be some good reason for its existence, and this reason is doubtless to be found in the wonderful properties of the eye itself. We all know how much of attraction, repulsion, love or hate, may be expressed by a glance, and how intensified is this power of expression in certain individuals. There is unquestionably some innate, inexplicable power in the human eye, although more apparent in some persons than in others, and we can readily understand how the people of Ireland believe that every individual possesses this faculty at some period in his existence, and that it is some- times hereditary, like other physical and mental characteristics. The influence of the human eye over the inferior animals is well known, and much has been written concerning the fascinating powers of the serpent, although in the latter case modern biology has shown thattheresult is due not so much to the eye of the serpent as to the paralyzing effect of fear upon his victim. Droc's'uil, the "bad eye,"* is the name given to the evil ej'e in the Gaelic-speaking districts of Ireland, while it is known as the bad eye in the east, and the ill eye in the north. The act of fascination is called deanad' droc'-s'iiilj, "making a bad eye," or overlooking. Those who possess this blighting power are generally unaware of its presence in themselves, and the evil consequences of its influence are not usually the result of any malevolent desire upon their part. The evil ej^e, either in man or woman, is generally due to some omission or irregularity in the ceremony of baptism. Should any word of the prescribed formula be forgotten, or should the sponsor fail to give the surname of the child as well as the name about to be conferred upon it, the infant will, in spite of itself, come into possession of this dreaded power. The idea under- lying this belief may be that, as the child is born in a state of original sin, it is under the influence of the evil spirit until sanctified by baptism, and that if the ceremony be improperly performed, a part of this influence still remains and manifests itself in the evil eye. In some instances the droc'-s-uil is hereditary, and there are even cases where it exists among all the relatives of the same surname. A notable example of this occurs in the western part of the County Clare, where all the members of a family named Mearnan are known to possess an evil eye, even to the re- mote degrees of kinship. Xotwithstanding this, they are much esteemed for their upright character, as it is well understood that this mysterious power is not subject to their own control. This family is referred to, but not named, in Hall's Ireland (III, page 2.50), a book published about forty years ago. The stories given further on concerning the Mearnans were obtained, with others, from natives of the County Clare, who were well * Pronounced, dhn'ikh-uil. tPronounced, jeenoo dhrukh-uil. Mooney.] -L4:0 [April 15, acquainted with the family. "While the evil eye belongs to some persons in a special manner, every man, woman and child possesses this faculty unawares once in every twenty-four hours, and a single glance at such a time is followed by all the ordinary disastrous consequences. This ex- plains many mysterious cases of sickness otherwise unaccountable. As has been shown, sickness and death sometimes result from the un- conscious glance of one possessed of the evil eye, without any desire upon his part to injure the victim. Should a person, however, known to pos- sess an evil eye, speak admiringly of another, praising his good looks, his healthful color, or his robust physique, or speak in a similar manner of his child, his cow, his crops, or anything belonging to him, it is inferred that he intends evil toward the person or thing thus spoken of, and meas- ures are at once taken to prevent it. In many cases the evil-minded per- son is compelled by the injured man, on pain of bodily damage, to spit upon the object of his pretended admiration, and at the same time to in- voke a blessing upon it. In Connamara a bowl is sometimes sent around the neighborhood, and each person to whom it is presented is expected to spit into it. The bowl is then taken home, and the person or animal over- looked is anointed with the spittle. The object of this is to obtain the spittle of the person responsible for the injury without giving him offense or awaking his suspicion, as a direct appeal to him would be certain to do. "When the spittle cannot be procured, the same result is accomplished by burning near the atHicted person a piece taken from the clothing of the one who has overlooked him. Should any one accidentally meet a person suspected of an evil eye, its influence may be averted by doubling the thumbs under the fingers. This gesture, and the measures just mentioned, are used throughout a great part of Europe for the same purpose. It has been asserted that the closed hand is used from its fancied resemblance in shape to the initial letter of the Hebrew name for God ; but while the name of the Hebrew letter also signifies a liand, the equivalent Phoenician and Egyptian hieroglyph is an open, instead of a closed hand. It seems also to be of different origin from the ancient Italian gesture still used to avert the evil eye, which is made by extending the first and fourth fingers, and is supposed to have had reference originally to a pair of horns. The true reason for using the closed hand probably lies in the fact that in this position the thumb and finger form a cross. In all Catholic countries it is a common practice to make the sign of the cross as a protection against dangers, especially those which are due to the influence of evil spirits. This sign is usually made upon the forehead, while occasionally the second finger is simply crossed over the first, but the method of the closed hand would naturally be adopted in this case to avoid attracting attention, just as an entire neigh- borhood is sometimes laid under contribution for spittle in order to avoid giving offense to the suspected party. "When an illness is thought to be due to the influence of the evil eye, the beanfeasac who makes a specialty of such cases is called in to deter- 1887. J i-'iJ [Mooney. mine the matter, and to point out the author of the trouble, but her office seems to go no further, as the mode of cure is generally understood. Anything which renders an individual conspicuous is liable to attract the attention of the evil pye — a belief also held by the Turks — and this explains some Irish blessings which are intended and regarded as curses. A common one of this kind is, Go mheid' ha b'dna do c'uid ha, go mheid' teac air an nirde do t'eac, agvs go mheid' bean h'reag' do b'ean.* "May your portion of cows be white cows, may your house be a house upon the height, and may your wife be a fine woman." Here the real wish of the speaker is that the conspicuous color of the cattle, the prominent position of the house upon a hill, and the pleasing qualities of the wife, may attract the attention of the evil eye to the possessor. A few of the stories related of the Mearnans will illustrate the various phases of this belief. They are given substantially as told by the narra- tors. Two parties of men were one day at work in the field putting up the hay into reeks, and one party was getting ahead of the other. A man of the slower party called the attention of a comrade named Mearnan to this fact. " Never mind," said Mearnan, "just wait." The others had their reek finished first and were just putting the top on it, when the whole pile fell over, burying the men under it, and Mearnan's party came out ahead. Another one of the same family stopped one day to admire a fine mare. As he started to go, a neighbor suggested to the owner that Mearnan ought to bless the mare. Much against his will he was compelled to come back, bless the animal and spit upon it. Soon after the mare had two foals, which were both dead, and if he had not blessed the mother she would have died likewise. The same man was one day passing along the road when he stopped to admire a horse in an adjoining field. The next day the animal, in attempting to jump across a ditch, fell into it and could not rise again. The owner and several of the neighbors tried for some time to get the animal upon its feet, without success, until at last one of the men remarked to the owner, " Micky, didn't Mearnan say yesterday that was a fine horse ?" " He did," says Micky. " Well, then, you send for him and make him spit on it." So Mearnan was sent for, and whether he liked it or not he had to come. As soon as he laid his hand upon the horse the animal neighed. He said, " God bless you," and spit upon it, and the horse at once climbed up out of the ditch. The owner's wife, who was looking on, said to her husband, " Faith, Micky, if spitting ever got a horse out of the ditch, and it did yours today." A woman of this name caused an accident to her little boy, just learn- ing to walk, on three several occasions, by calling attention to his agility in climbing up on the table or the dresser. Each time he fell down from his elevated position and broke his leg.

Mooney.] lOU [April 15, time her brother, who well knew the reason of it, told her that it washer fault, in not having blessed the child when she spoke of it. The mother would not believe it, and insisted as strongly that the brother was respon- sible for the accident. When the boy grew up he was obliged to wear trousers instead of knee breeches to conceal the deformity caused in this manner. This woman one day met a young man going to church, and carrying his shoes in his hand, as the road was muddy. She made some complimentary remark about his feet, and when the young man got home from church they were turned inward, and he was unable to stand upon them. The woman was sent for and compelled, very unwillingly, to bless his feet and spit upon them, but as she was going out of the door she turned round and said, "May it never thrive with you." The young man recovered the use of his feet, but there was always a twist in them afterward. In tliis climate a tramj) of several miles barefoot over a muddy road, together with kneeling or standing for two liours in a cramped posi- tion on the cold floor of a church, might have resulted in rheumatism. One of the Mearnans was so well aware of this blighting influence in himself, that on entering a house to pay a visit he would always spit upon and bless each member of the family before sitting down. A number of men, including two carters with their horses, were one day at work in the County Cavan, when one of the party happened to say something in praise of the animals. On quitting work for the day the horses were found to be sick, and soon lay down and were unable to rise. Several remedies were tried without avail, until some one told the owner of one of the horses that the man who had praised them in the morning had an evil eye, and advised him to get him to spit upon them. He said he could not do that, as that man had a grudge against him. His friend then told him to get a piece of the maji's clothing and burn it near the horses. That night the carter secretly cut a piece from the coat of the man who was responsible for the trouble, and going out to the horses he get fire to the rag and held it first near the head of his own animal and then near the other. In the morning his horse was well and the one belonging to the other carter was dead. The virtue was gone from the cloth before it reached the second horse. As the one who related the inci- dent said, it was, "Man, save yourself." In this instance the knife used belonged also to the owner of the coat, but this had no effect upon the result. The Blessed Wells. In addition to the practitioners of various kinds, the people have great recourse to the numerous "blessed wells" throughout the country. The religious veneration for healing wells is older than history, and is found, not only in Ireland, but throughout Europe and Southern Asia. It is fre- quently referred to in the Bible, the most notable instance being that of the pool of Bethesda. There seems to be nothing of the kind among our Indians, who, although they regard certain localities with peculiar rever- 1SS7.] 10 i [Mooney. ence as the abodes of invisible manitos, to -^-hom they never fail to make some offering in passing, yet apparently do not attach any healing powers to such places. There are hundreds of these wells in Ireland, at least twenty being in the Count}' Galway alone. They are generally dedicated to some saint, and there is always a legend to account for their origin. Thus Coluni- Cille's well, at Kells, in the County Meath, sprang up from the floor of the saint's house while his mother was lying on a sick bed, thirsting for a drink. In many, and perhaps in most cases, ancient Druidic remains or round towers are found near them, showing that these have been places of religious resort even before the dawn of Christianity. Should one of these wells be defiled, it would at once cease to flow, and the perpetrator of the sacrilege would wither away under the curse of the patron saint of the spring. The water must not be used for ordinary purposes. Incidents are related of women, who, being in haste to prepare a meal, have taken water from a blessed well close at hand rather than go to another spring at a distance, but found, after exhausting their patience in fruitless efforts, that it was impossible to bring the water to a boil. This is perfectly true, as the strong mineral impregnations which give the water its medicinal virtues, render it extremely difficult to boil under ordinary circumstances. There is usually a fish, a worm, or a peculiar stone at the bottom of the well, and the circumstances attending its appearance are regarded as omens of success or failure in obtaininsi relief. On departing from the well, pilgrims leave behind some small token of their visit, generally a shred torn from the clothing, which is twisted into the ivy that clambers up the rock, or hung from the limb of a tree overshadowing the water. These trees may be distinguished afar off by the number of rags sus- pended from their branches and fluttering in the breeze. This is an ancient custom, and is still practiced in Southern Asia as far east as Ceylon, and throughout Northern Africa, and along the east coast as far south as Zanzibar. Cripples who have recovered the use of their limbs leave also "the crutches and litters used in coming. Besides the wells, there are many small lakes and waterfalls which are visited for the same purpose. Many of these wells have been deserted since the great famine of 1847-8. While religious exercises are a prominent feature at all these resorts, there are some which are visited principally from motives of devotion. Chief among these is the celebrated Lough Dearg, in Donegal, which was resorted to by pilgrims from all parts of Europe during the Middle Ages, and where the rigid discipline imposed upon the penitents in its subterra- nean caves is said to have served as the model for Dante's Purgatorio. The wells are resorted to for almost everj' variety of ailment, but there are some which are especially noted for the cure of particular diseases, such as ulcers, sore eyes, or rheumatic affections. The pilgrims frequently come from long distances, sometimes even walking a hundred miles. The exercise, which is known as "making the stations" or "going a round," 1 ^'>. Mooney.] -«-«-/ -j [April 15, is sometimes performed by proxy, or by the invalid after recovery in accordance vfith a vow made during his illness. In the latter case, he is generally accompanied by a friend, who goes through the same exercises. The sanitary part consists of immersion, shower baths — where the water falls over a rock — rubbing and drinking the water. The operation is gene- rally repeated on three, sometimes on seven or nine consecutive mornings, while the patient is still fasting. The religious part consists of the repe- tition of a number of prayers, usually the Our Father and Hail Mary, or the two combined in the rosary. While reciting these prayers the patient walks or is led around the well a certain number of times, always follow- ing the course of the sun. The circuit is frequently made upon the knees, and in every case the pilgrimage is undertaken and carried out in a spirit of deep religious fervor. The wells are visited at all seasons of the year, but the favorite time is the day consecrated to the patron saint of the well. In some cases a re- markable phenomenon takes place at a certain hour, and is awaited by the people as the signal for entering the water. Thus St. John's well, a noted well at Kilcarty, in the County Meath, is visited on St. John's eve — June 23, or midsummer eve, the great fire festival of ancient and modern Ire- land. Just at midnight a mist rises from the surface of the water, on see- ing which those in waiting begin the circuit around the well. A similar phenomenon is related of Lough Ee-Cinlaan, a small "blessed lough" near Kenmare, in the County Kerry, which is also visited on St. John's eve and the following day. At a certain hour three "tussocks" of float- ing grass in the middle of the lough begin to move around in a circle, upon which the people waiting on the bank go down into the water. Compare this with the Bible account of the pool of Bethesda, which was surrounded by five porches. "In these lay a great multitude of im- potent folk, of blind, halt, withered, waiting for the moving of the water. For an angel went down at a certain season into the pool and troubled the water. Whosoever then first after the troubling of the water stepped in, was made whole of whatsoever disease he had."* In each case the re- markable appearance is doubtless owing to the same causes which govern the periodic movements of geysers and other intermittent springs. In the lough just mentioned, one of the three tussocks always moves around in the rear of the other two, which, like everything else in Ire- land, is accounted for by a legend. They formerly moved along abreast, until one day a sacrilegious wretch attempted to mow the grass for his own use The moment he struck his scythe into the first tussock, blood followed, as from a living thing, and dyed the waters of the lake. Terri- fied at the sight, he desisted from his purpose, but ever since the Avounded tussock has limped behind its fellows. A brief extract from a recent Irish letter, written in reply to some ques- tions concerning the blessed wells of the County Galway, will give a John V : 3, 4. 1887.] lOd [Mooney. better idea of the present beliefs and practices in this connection than many- pages o (description. The writer is one of the people, and has been familiar all his life with the customs which he describes so accurately. The extract is given in his own words, with the exception of a few slight grammatic changes. The letter is written from Curuamona, near Clon- bur, about twenty miles north-west from the town of Galway : " Thubber Muira and Feheen, in Ballintubber. Noted to cure any kind of sickness that may occur in a family. Station days are the eve of any of the Lady Days — eighth of September, fifteenth of August and second of February. The stations are performed thus : "The person will kneel before the wells barefooted, will say so many- prayers, and will take in his right hand seven pebbles, of stones which are for the purpose at the mouths of the wells. After walking around the well he will drop a pebble at each round, will kneel again and say more prayers, and so on until finished. There is one remarkable thing about these wells. After promising a station at these wells, if a person goes and prays there, he will see a small worm ; and if the worm lives (i. e., is alive) the patient will recover, and if seen dead the patient will 'die. After performing a station here, if it be a male person he will drop a but- ton in the well, sometimes a piece of coin, etc. ; and if it be a female, she will pull some threads oat of ber shawl or some part of her clothes, which she ties on the bush that covers these wells. Persons abroad promise sta- tions at these wells and get some of their friends on this side to perform them, which must be done by two persons together." In this instance there are two wells at the saine locality. The name of the principal one, Thubber Muira,* or "Mary's well," shows that it is dedicated to the Blessed Virgin, and consequently the favorite times for visiting it are the " Lady Days," or days specially devoted to her honor. These are named in the order of their importance, which is the reverse of the chronologic order. Feheenf is the name of a saint of local celebrity, and is sometimes rendered by Festus. It is to be noted that the name of the place, Ballintubber, :j: signifies the "town of the well," showing that the village owes its name, and perhaps also its origin in the remote past, to the presence of the spring in its vicinity. The water is probably used as previously stated, according to the nature of the complaint. A second extract from the same letter furnishes an excellent illustration of some of the beliefs connected with these wells, aside from their healing powers. After describing Thubber Enue, or Eneas' well, which springs out of a rock in the hill of Doon, in the same region, and is especially noted for the cure of sore eyes, the writer goes on to say, "There was another remarkable affair about this well— a kind of a round stone, called * Gaelic, Tobar Muire.

For in- stance, if one person belied anotiier, or gave scandal by any means, then the person would go and offer those prayers and turn the lyoc, and who- soever of them would be in the fault, he was sure to die ; but what- ever time of the year this would occur, it was sure to be followed by bad weather, thunder and rain. So the farming class was almost ruined by this work, and the people practicing it more and more, until at last the clergy got the lyoc taken away and thrown into the deepest spot of Lough Corrib — and more was the pity, for the people were not so often at that time going to petty sessions as they do now ; they were leaving it all to God and Lyoc Emi£." In another letter, dated January 20, 1887, the same writer thus men- tions a noted waterfall in the same neighborhood : "There is a waterfall convenient to this place that cures pains of the back. The patient goes in his or her nakedness, for about ten minutes, under this waterfall, and the third time is sure of being all right. The only thing given down for this is, that a priest in the time of Shawii-na-Sogyarth\ was concealed for twenty-four hours under this waterfall." Whatever may be thought of the theory in this instance, it is plain that the treatment is exactly that adopted by the best surgeons in dealing with sprains and similar ailments, including "pains of the back," viz., subjecting' the afiected part to the action of a stream of cold water falling from a considerable elevation. The pool of Bethesda at Jerusalem has already been noticed in this con- nection, and a comparison of the present Irish beliefs and customs in this regard with the Bible story ofNaaman will show that they are substan- tially those which existed among the Jews nearly three thousand years ago. Naaman was a Syrian general, living at Damascus. He was afflicted with leprosy, and at last, by the advice of his friends, undertook a long JDurnej'^ to Samaria to procure the help of the prophet Elisha. When he had reached the latter city, "Elisha sent a messenger unto him, saying, Go and wash in Jordan seven times, and thy flesh shall come again to thee and thou shalt be clean. * * * Then went he down and dipped himself seven times in Jordan, according to the saying of the man of God ; and his flesh came again, like unto the flesh of a little child, and he was clean.":]: In this case the Syrian practice seems to have been difler- ent from that of the Jews, as Naaman had expected that the prophet would cure him by simply touching the diseased part and invoking the name of his God. There can be no doubt that these " blessed wells " of Ireland are min- eral springs of great medicinal virtues, as the wliole country is a mineral region, containing coal and iron in abundance, with limestone cliffs along * Gaelic, Leac Aong'us " Eneas rock, or slab.

We should thus expect to find in these wells the same constituents that give a reputation to the mineral springs of the mountain region of Vir- ginia and Pennsylvania, According to Dr. Jolin Rutty, the author of two valuable works* on the mineral springs of Ireland and of Europe in gen- eral, some of the Irish wells commonly resorted to by the people are equal to any of the celebrated continental spas, while those noted for the cure of particular diseases contain just the constituents most beneficial in such cases. Tlie ordinary impregnations are combinations of iron, lime, soda, magnesia and sulphur. In addition to these, many wells and streams are impregnated with petroleum and bituminous compounds, owing to their vicinity to the bogs, which contain large quantities of half- fossilized pines and other resinous conifers. It is a well-known fact that bog water has preservative qualities, and bodies of persons drowned in these bogs have been recovered long afterward still undecayed. There are also some streams and lakes, notably Lough Neagh, whose waters have petrifying properties. Were Ireland free to develop her own resources, not only would her neglected mines and marble quarries be made available, but her healing springs, now visited only by barefooted peasants, would speedily acquire a reputation, which, together with the natural beauties of the country, would attract thousands of those who yearly seek health or pleasure on the continent. There is nothing but simple truth in the proud boast of the people of Ireland that in their native country the grass is always green, the soil harbors no venomous reptile, and the waters are blessed. Miscellaneous Charms. Besides the blessed wells and the sig'efreog, the people have a number of charms for various diseases — in fact, it is probably safe to say that they have a charm for every malady, real or imaginary, that ever existed. Many of these charms are accompanied by verses or other formulas, which have been handed down for generations, and there is generally a legend to explain the formula. A. few of these charms are here given. It must be stated at the outset that the application is always made in the name of the Father, Son and Holy Ghost. Should any one become sick in church while wearing a garment sewn on Sunday, it will be impossi- ble to cure him. Epilepsy is c&Wed tinneas »io?',f the "great sickness," and is regarded with such dread that it is seldom mentioned except under some figurative name. The patient is cured by drinking milk boiled in a human skull. An "essence " prepared from a human skull was formerly used in Italy lo cure the same disease, according to a medical work published in that • A Mettiodical Synopsis of Mineral Waters, &c., and Essay Towards a Natural, Exper- imental and iVIedicinal History of the Mineral Waters of Ireland. + Pronounced chinyas moer. Mooney.J ^'^^ [April 15, country in 1726, and the skull of one who had died a violent death was preferred, being considered to retain more of the vital principle. Toothache is cured by rubbing the gum with the finger of a corpse, or washing it with some of the water used in washing the corpse when pre- paring it for burial. The cure is permanent. The pain is commonly sup- posed to be caused by a small worm eating the tooth, and this worm is sometimes killed by applying to the tooth a piece of tobacco, guano, or some other pungent substance. The Omaha Indians, who hold the same theory, kill the worm by blistering the skin on the outer surface of the jaw. The dead hand holds an important place in Irish mythology. Headnclie is Q&WaiX flab'ras beag,* or "little fever," and is caused by the joints of the skull springing apart until "the head is open" — ^just as we sometimes hear a man under such circumstances say that his head is split- ting. The woman who has the cure takes a woolen string, with which she measures the head of the sufferer in three different directions, in order to see how far it is open. First the string is put under the chin, and the ends are brought up over the top of the head. Next it is measured in the same way from under the nose to the back of the head, bringing the ends of the string across just above the ears, and finally the string is drawn around the forehead and over the temples to the back of the head. Having learned how much the head has opened, she presses it firmly between her hands to bring the sutures together, says certain words, and the cure is effected. In one instance the patient was told that his head had opened something more than an inch. There may be more virtue in this method than is at first apparent. Earache is cured by putting into the ear a piece of wool from a black sheep, saturated with oil, at the same time reciting the appropriate words. The last remark holds good also of this cure. Sore throat is cured by putting the head of a live gander into the mouth of the patient and making it scream down his throat. The thrush in chil- dren is cured in a similar way, by getting a posthumous child to blow into the mouth of the sufferer. The blowing must be done by the ()perator while still fasting, and is generally repeated for three successive morn- ings. Some persons can " set a charm " to staunch a icound so that not a drop of blood shall flow from it. The charm is said to consist solely in the repetition of certain words, without any application whatever. A hemor- rhage can be stopped instantly by the application of a garment, which has been washed or ironed on Sunday. There are several cures for a sprain. The most common method is to tie around the joint ^fogee, or worn-out thread from a loom. Sometimes a string is used which has been held in the mouth while a certain charm is recited. The most remarkable method is used in Kerry, both for men * Pronounced feveams Vyug. 1887.] 157 [Mooney. and animals, and is here given without comment, as described by a man ■who saw the operation performed at his own house for the cure of a lame horse, which recovered before morning. There is a thorny shrub, known in that county as sgeac'-vvadera* or "dog briar," whose white flowers are fixed close to the stem, while its thorns point downward. As our Savior, when a child, was one day walking with His mother, they met this briar and admired its flowers. The Mother tried to pluck one of them, but could not reach it until the briar bent down to her grasp. Since then its thorns always bend downward. To perform the cure a rod about three feet long is cut from the sfjeac'-m'ddera and split down the middle. Two men then stand close together, facing each other, each one holding against his body, at the right and left side, one end of the two pieces thus made, while his companion holds the other two ends in the same manner. In a short time the two rods begin to bend in toward the centre and gradually approach each other until they are firmly united for about six inches of their length in the middle. The man who sets the charm — a third party — then cuts off this portion and lays it upon the sprained joint, repeating certain words at the same time. The rest of the stick is thrown away. This charm never fails, excepting when there is a stain upon the birth of one of those holding the rods. Scrofula, or the evil, is sometimes cured by applying a little powder from a deer's horn, which is kept in houses for this purpose. Another common method is to apply the blood of nine or twelve young wrens. The number must be decided by the ornithologist, as they take the whole brood, which, according to some persons, always consists of twelve birds, while others say there are only nine. This blood is called fuil rig'e\ or "king's blood," for the wren is the king of birds in Ireland as in Ger- many. There may be some connection between king's blood and king's evil. The water of St. John's well, already referred to, is also noted for curing this disease. The cure for sore eyes due to the presence of some foreign body, is best described by an incident, given as related by the man who was cured by the operation. While gathering seaweed on the strand he got somethin»' [Mooney. idea here is similar to that just mentioned. In Connamara for the same trouble ten joints (the knots only) are cut from an oat stalk, nine of which are tied up in a small parcel, while the tenth is thrown away. Tlie parcel is left at the crossroads, and the warts will go to the one who picks it up. The idea here is also common in European folk-lore, and almost the same method is used in Switzerland. The selection of ten similar objects, one of which is afterward thrown away, appears also in the account already given of the child cured of convulsions. It is also proper to mention here that oats are the sacred grain in Irish mythology. Another method is, on rising in the morning, to spit upon the hearth while still fasting, and then rub the spittle upon the wart with the second finger. The first finger is never used for rubbing spittle or ointment upon sores of any kind, as it is supposed to have a poisonous effect. The operation is repeated every morning until the wart disappears. Another method, used in Galway, is to bathe the wart witli water found lying in a depression in the surface of a rock, saying at the same time : " Uisfje cloc'a gan ia/rraid', Ni'g t'iarraid' td me."* " Water of a stone without seeking. It's not seeking for you I am." As the words of the formula imply, the water must be found accident- ally, no benefit resulting from its application when a deliberate search is made for it. In a case resembling asthma, where the patient, a boy about seven years old, felt a constant choking sensation and was rapidly losing flesh, he was taken by the old man who had the cure, and placed standing with his back against a tree growing in a field — the tree, in this instance, being an apple tree. A hole was then bored in the tree just above the child's head, a lock of his hair cutoff and placed in it, and the opening closed up again. Although not mentioned by the informant, some words were undoubtedly repeated at the same time. As the boy grew above the hole in the tree, he grew away from the disease. A well-known charm used in cases oi decline, or incipient consumption, may be described by giving an instance, without comment, as related by an eye-witness. A young girl of lively disposition suddenly lost health and spirits, and appeared to be rapidly sinking into the grave, wlien her friends persuaded her to visit an old woman who offered to cure her. On arriving there the woman filled a tumbler with oatmeal, even with the top, and wrapped a thin cloth around it. Then loosening the girl's dress she applied the mouth of the tumbler first to her back, then to her side, and lastly to her bosom. On removing the cloth from the tumbler it was found that half the meal had disappeared. The glass was refilled and the * Pronounced, Ish'/a cirikha gun eerree, Nee g 0 > r 1887.] • -*^^' [Barker. made by the Clarks, but wliich, although of slightly less aperture — half an inch — was provided with a photographic correcting lens. The large amount of work done with these instruments appears from the fiict that at the time of his death in 1883, he had taken more than a hundred stellar spectrum photographs, the later ones having a comparison spectrum upon the same plate. The methods employed both by Dr. Huggins and by Dr. Draper in all their later work were in general the same. The light of the star was concentrated by the object glass of a large teles,cope upon the slit of a spectroscope placed at its focus. In consequence, a narrow slit was neces- sary in order to obtain good definition, and very perfect adjustment of the driving clock was required to keep the image of the star upon the slit. The spectra thus obtained were of course quite minute ; being about half an inch only in length, and only one sixteenth or thereabouts in width. Dr. Huggins made use of a cylindrical lens placed in front of the slit to obtain the necessary width to the spectrum. But Dr. Draper secured this end by throwing the image of the star slightly out of focus. The first attempts to obtain photographs of stellar spectra which were made at the Harvard College Observatory were undertaken in May, 1885, by the aid of an appropriation from the Ruraford fund of the American Academy of Arts and Sciences. In these experiments an entirely new photographic method was adopted. The prism was placed in front of the object glass of the telescope ; a plan originally suggested for eye observa- tions by Fraunhofer in 1823* and employed subsequently, practically, by Secchi and Respighi. The advantages, for photographic purposes, of this method are twofold: First, the loss of light is extremely small; and second, the stars over the entire field of the telescope will impress their spectra upon the plate. Hence while previous observers could photo- graph but one star at a time, and this satisfactorily only with stars of the first or second magnitude, more than one hundred spectra have now been simultaneously obtained on a single plate, many of them of stars no brighter than the seventh or eighth magnitude. The earliest photographs obtained at the Observatory were taken by placing a prism whose refract- ing angle was 30° in front of a Voigtlander photographic lens of two inches aperture and about seven inches focal length. No clock-work was used, the spectra being formed of the trails of the stars. In the spectrum of the Pole-star thus taken, over a dozen lines could be counted ; and in the spectra of a Lyne and a Aquila?, the characteristic lines were shown, even when the time of exposure was only two or three minutes. In the autumn of 1885, an appropriation was made from the Bache fund of the National Academy of Sciences for the purpose of continuing these investigations. A prism of 15° refracting angle and eight inches in clear aperture was employed, placed in front of a Voigtlander photographic lens having an aperture of eight inches and a focal length of about forty-five inches. The details of the method are thus described in the report of Prof. Pickering :t *See Schellen's Spectrum Analysis, English ed.. 1872, p. 462, ct seq. • t Memoirs Am. Acad. Arts and Sci., xi, 209, 188C. Barker.l ^^^ [April 1, "The prism was always placed with its edges horizontal when the tele- scope was in the meridian. The spectrum then extended north and south. If clock-work was attached, a line of light would be formed, too narrow to show the lines of the spectrum satisfactorily. The usual method (»f re- moving this difficulty is the employment of a cylindrical lens to widen the spectrum; but if the clock-work is disconnected, the motion of the star will produce the same effect. Unless the star is very bright, the motion will, however, be so great that the spectrum will be too faint. It Is only necessary to vary the rate of the clock in order to give any desired width to the spectrum. A width of about one millimeter is needed to show the fainter lines. This distance would be traversed by an equatorial star in about twelve seconds. The longest time that it is ordinarily convenient to expose a plate is about an hour. If then the clock is made to gain or lose twelve seconds an hour, it will have the rate best suited for the spectra of the faintest stars. A mean lime clock loses about ten seconds an hour. It is only necessary to substitute a mean time clock for the sidereal clock to produce the required rate. It was found more convenient, however, to have an auxiliary clock whose rate could be altered at will by inserting stops of various lengths under the bob of the pendulum. One of these made it gain twelve seconds in about five minutes, the other produced the same gain in an hour. The velocity of the image upon the plate when the clock is detached could thus be reduced thirty or three hundred and sixty times. This corresponds to a difference of 3.7 and 6.1 magnitudes respec- tively. Since the spectrum of a star of the second magnitude could be taken without clock-work, stars of the sixth and eighth magnitudes re- spectively could be photographed equally well with the arrangement de- scribed above." The work already undertaken in this direction developed so rapidly that the Bache appropriation soon proved entirely inadequate to carry it fur- ther. Whereupon early in 1886, Mrs. Henry Draper, who from the first had taken a great interest in this work as a continuation of that so auspi- ciously begun by Dr. Draper himself, generously came forward and agreed to place at Prof. Pickering's disposal, not only the excellent eleven inch photographic telescope which Dr. Draper had so successfully used in his spectrum researches, but also a sufficient sum of money to enable the experiments already suggested to be fairly tried. In consequence. Prof. Pickering decided to continue the investigation along three more or less independent lines : First, he purposed to make a general survey of stellar spectra, each spectra being photographed with an exposure of not less than five minutes. These photographs exhibit in general the spectra of all stars brighter than the sixth magnitude, with sufficient distinctness for measurement. Second, he desired to undertake a determination of the spectra of the fainter stars, each photograph of this set receiving an expo- sure of an hour. All stars not fainter than the ninth magnitude, and in- cluded in a region ten degrees square, are represented upon a single plate. The work in both these directions has been done thus far with the Bache 1887.] lb J [Barker. photographic telescopes, 15,729 spectra having been already photographed and measured. Third, he decided to carry on a more careful study of the spectra of the brighter stars. For this work, the Draper eleven inch cor- rected refractor was specially used, a suitable observatory having been erected for it in Cambridge. Four prisms, each having a refracting angle of 15°, were constructed, of which three had a clear aperture of nearly eleven inches, the fourth being somewhat smaller. These four prisms with their mounting weighed more than a hundred pounds and occupied a cubic foot of space. The original negatives have been enlarged by a novel process which gives most excellent results. A cylindrical lens is placed close to the enlarging lens with its axis parallel to the length of the spectrum. In the apparatus actually employed the length of the spectrum and with it the dispersion, is increased five times, while the breadth is increased nearl}'- one hundred. This arrangement has the great advantage that it greatly reduces the difficulty arising from the feeble light of the star. Until re- cently, the spectra in the original negatives were made very narrow, since otherwise the intensity of the starlight would have been insufficient to produce the proper decomposition of the silver particles. The enlarge- ment being made by daylight, the vast amount of energy then available is controlled by the original negative, the action of which may be com- pared to that of a telegraphic relay. The copies therefore represent manj^ hundred times the original energy received from the stars. It was with the apparatus above described and under these conditions, that the photographs were taken that I have the honor of exhibiting to the Society. Although the earliest satisfactory results were obtained in Octo- ber, 1886, yet it is evident that the full meaning of these photographs can be discovered only after they have been carefully measured, and after these measurements have been reduced and thoroughly discussed. Some points of interest, however, appear on simple inspection of them. This photograph of « Cygni for example, which was taken November 26, 1886, shows the H line to be double,* its two components having a differ- ence of wave-length of about one ten-millionth of a millimeter. This photograph of o Ceti shows the lines G and h as bright lines, as well as the four ultra violet lines which are the characteristic of spectra of the first type ; to which Dr. Iluggins gave the letters a, /?, ;' and S. In this spec- trum, however, the H and K lines are seen to be dark ; showing that they do not belong to that series of lines. The spectrum of a Tauri shows a mul- titude of lines and bands, massed in the more refrangible region ; thus ac- counting for the ruddy color of the star. The spectrum of Sirius shows, besides the well-known broad lines characteristic of this brilliant star, a large number of fainter ones. The spectrum of a Canis minoris, taken with four prisms, shows the solar dark lines G, h, H and K. This entire research is entitled " The Henry Draper Memorial."

It is illustrated with a plate (which I have the pleasure of placing before you) illustrating the rapid progress which has been made within the past few years in photographing stellar spectra. The first figure, which is a direct copy of the spectra obtained in 1885, was taken with the Voigtl3,nder lens of two inches aperture having a 30° prism in front of it and shows the spectra of a. Lyr*, « Aquilae, a Bootis and /9 and Y Urste Majoris ; the instrument having been directed successively to these stars and the plate exposed five minutes on each. The longest of these spectra is not over four millimeters in length. The second figure is the spectrum f Ursff Majoris accompanied by that of an adjacent fifth magnitude star. It was taken with the larger VoigtlJinder lens, with an ex- posure of five minutes. It is about nine millimeters long and one wide, and illustrates the size of spectra used in preparing the catalogue of spec- tra of the brighter stars, one or two hundred of these being sometimes photographed on a single plate. The third figure represents the spectrum of a Lyrre, and was taken with the Draper eleven-inch telescope with two prisms, on November 5, 1886, with an exposure of fifty-nine minutes. This spectrum is a little more than fifty millimeters long and about two and a half millimeters wide. The fourth spectrum, taken on January 21, 1887, represents /? Geminorum. The exposure was fifty minutes, four prisms being used with the eleven-inch Draper telescope. This spec- trum is nearly eighty millimeters long. All these now described are original negatives printed by contact. The fifth figure in this plate represents a little more than half of the spectrum of /5 Geminorum (as given in figure four) enlarged by Prof. Pickering's special process above described. This spectrum is 220 millimeters long and seventy-five wide, and shows a mass of dense lines irregularly distributed. Below this Is a narrow strip, fifteen millimeters wide, of the spectrum of the same star taken on January 12th. It is given for comparison and shows that practically all of the lines shown belong really to the star itself and are not produced in the photographic processes. It is gratifying to know that Mrs. Draper has been so well satisfied with these splendid results that she has decided greatly to extend the original plan of the work and to have it conducted in the future on a scale suited to its importance. The attempt will be made to include all portions of the subject so that the final results shall form a complete discussion of the constitution and conditions of the stars as revealed by their spectra, so far as scientific methods at present permit. It is expected that a station will be established in the southern hemisphere, so as to permit the work to be so extended that a similar method of study may be applied to stars in all parts of the sky. The investigations already undertaken include (1) a catalogue of the spectra of all stars north of 24^, of the sixth magnitude or brighter, (2) a more extensive catalogue of spectra of stars brighter than the eighth magnitude, and (3) a detailed study of the spectra of the 1887.] -'■'-'- [Barker. bright stars. This hist will include a classification of the spectra, a de- termination of the wave-lengths of the lines, a comparison with terrestrial spectra and an application of the results to the measurement of the ap- proach and recession of the stars. A special photographic investigation will also be undertaken of the spectra of the banded stars and of the ends of the spectra of the bright stars. Beside the instruments already men- tioned, there will be used the twenty-eight-inch and fifteen -inch reflectors constructed by Dr. Draper, which Mrs. Draper has decided to send to Cambridge for this purpose, and also the fifteen-inch refractor belonging to the Observatory. From these statements it will appear that photographic apparatus has here been provided on a scale quite unequaled elsewhere. "But," says Prof. Pickering, "Mrs. Draper has not only provided the means for keeping these instruments actively employed, several of them during the whole of every clear night, but also of reducing the results by a considerable force of computors and of publishing them in a suitable form. A field of work of great extent and promise is open, and there seems to be an opportunity to erect to the name of Dr. Henry Draper a memorial such as heretofore no astronomer has received. One cannot but hope that such an example may ])e imitated in other departments of astronomy, and that hereafter other names may be commemorated not by a needless duplication of unsupported observatories but by the more last- ing monuments of useful work accomplished." Note added May 1, 1SS7. The excellent phototype plate which accompanies and illustrates this paper, shows the enlarged positives of the spectra of a Tauri taken with two prisms and that of o Ceti taken with one. The negatives from which the phototype plate was prepared were kindly furnished me by Prof. Pickering especially for this purpose. My obligations are due to him, therefore, for this courtesy. I am also indebted to ^Mr. Gutekunst for the faithfulness of their reproduction. It is a gratifying evidence of appreciation of Prof. Pickering's pho- tographic work, that the National Academy of Sciences, at its meeting in Washington, in April, awarded to him the Henry Draper gold medal, for having in their opinion made the most important progress in Astronomical Physics during the two years which have elapsed since the preceding award. Dr. Frazer made the following remarks : A question suggests itself in relation to the very important results of Prof. Pickering, which Prof Barker has so lucidlj^ and interestingly described. As the extremely minute point of light which is received on the first prism represents the radiation from every part of the star under examina- tion, of course the line of light produced by the prism will represent at any infinitesimal fraction of time, the whole radiation of light from the Stevenson.] li ^ [Uay 20, half of the star turned towards us during that time ; and during an inde- finitely short exposure might be said to represent the condition of the surface visible to us as it was during a certain minute time interval when the waves set out from that surface. [Neglecting for the moment the modification of this statement which the curvature of the star's surface would render necessary owing to the fact that the light which proceeded from the extreme outer edge would have a longer distance to travel than that in the centre by a little more than the radius of the star, and there- fore its arrival at the instrument might be later than that from the central portion. ] But the broadening of this line into a surface by making a slight differ- ence between the rate of the clock-work and the angular motion of the earth, would represent this same elongated surface of the star at differ- ent times. In other words the one axis would represent different parts of the star at the same instant of time, and the other axis would represent the same region (the hemisphere visible to us) at different periods of time. If the movements of the atmosphere of the star observed were as rapid and extensive as those of our own sun, the consequence would be that we would have a succession of different conditions of the star's atmosphere placed in close juxtaposition, the whole series representing all the changes that had occurred in the star's photosphere during the interval of expo- sure. On this account it would seem that this method was not adapted to do more than give the resulting average of these changes on a sensi- tive plate of measurable breadth and would not permit the condition of the photosphere at any one instant of time to be studied. It would be interesting to know what effect a similar procedure on the disc of the sun would show, by juxtaposing a large number of instantane- ous photographs of the disc as different parts of the latter were successively brought over the slit of the spectroscope. Notes on the Surface Geology of South-tcest Virginia. By John J. Stevenson. {Read before the American Philosophical Society, May W, 1SS7.) New river, rising in North Carolina, flows across the Archtean area of Virginia, and enters the " Great Valley" of that State in Wythe county. It flows througli Wythe and Pulaski counties, separates the latter from Montgomery, and flows through Giles county into West Virginia on its way to the Ohio river at Point Pleasant. It drains the counties named, with the addition of Bland. The most important forks of the Holston river flow through Smyth and Washington counties of Virginia into Ten- nessee ; while the Clinch river rising in Tazewell county of Virginia flows through Russell and Scott counties and drains much of Wise. It is joined in Tennessee by Powell river, which drains Lee county and part of Wise. 1887.] 1'^ [Stevenson. The Clinch and Holston unite to form the Tennessee, through which their waters reach the Ohio at Paducah, The effects of erosion in Bland county are seen in the removal of lime- stone and shales so as to throw the harder rocks into relief as mountains ; to form narrow valleys in limestones near the present lines of faulting, and to scoop out a basin in Devonian and Upper Silurian shales. Within Giles county. New river llows on Knox (Calciferous) limestone, and the later rocks have been eroded from a considerable space on both sides of the stream. The conditions became approximatelj' the same throughout this area after the removal of the Devonian and Upper Silurian, and good illustrations of certain types of erosion are afforded here as well as further southward along New river. Remnants of two planes of erosion, one 225 (1810 feet above tide) feet and the other 115 (about 1670 feet above tide) feet above New river at Snidow's forr}% were seen in Giles county on the road from the county- seat to that ferry, which is opposite the mouth of Big Stony creek, where the altitude of the water surface is about 1555 feet above tide. The upper plane originally extended far into the recess between Pearis and Sugar run mountains ;* and even now it can be recognized easily in the many hills, whose leveled tops have almost the same altitude. The second plane is more distinct, being better preserved than the other, and having a larger area. Still lower benches, river terraces, were seen, but thej'^ do not exist on the road followed by the writer, and no measurements of their height could be obtained. Tiie deposit on the higher planes is sand and clay, carrying vast num- bers of transported polished fragments, most of which are barely three inches in diameter, though some were seen upwards of ten inches. For the most part, these pebbles are of local origin, or, at least, they came from the confines of the "Great Valley," for the sandstones predomi- nate ; but there are not wanting pebbles of glassy and milky quartz, seldom more than four inches in diameter, which must have come from the Blue Ridge, not less than seventy miles away by the nearest water- line. And these are found on the highest bench at nearly three miles from the river's present channel way. A fine plane of erosion is well preserved on both sides of New river south from Little Walker mountain in Pulaski and Montgomery counties. Its summit is shown on the west side of the river near Belspring station, with an altitude of not fixr from 1775 feet above tide, the station being 1766 feet A.

Stevenson.] -L • 4 [Maj' 20, 1914 feet. This bench extends eastward from New river for more than eight miles between Little Walker and Price mountains, and it is probably the same with the fine terrace shown above the railroad bridge over New river. It is distinct on the west side at four miles from the river on the railroad ; and it appears to be the same with the plain seen nearly six miles further west on the road leading across Pulaski county from Dublin to Pearisburg ; but the barometric readings on that road are not wholly satisfactory. The deposit on these benches is of clay and sand, containing pebbles of varying size, most of them, as before, of local origin, but not a few of them have come from the Blue Ridge. The upper bench is deeply trenched here and there by narrow valleys in which rock exposures occur ; elsewhere such exposures are rare, as the detrital cover is from five to thirty feet thick. River terraces, apparently unbroken and almost as perfect as those shown in theoretical diagrams were seen in the "Horseshoe bend" bottom, but they could not be reached for measure- ment. Erosion planes are equally well marked along New river within Wythe county for some distance above and below the Wythe lead and zinc mines. The lead company has sunk a shaft at about half a mile south from New river, beginning at the topmost part of the bench, which, according to the barometer, is 310 feet above the river at Thorn's ferry opposite the com- pany's offices, or 2260 feet above tide. The surface is covered with loose boulders, mostly three inches or less, though some are fully eight inches. The deposit, as found in the shaft, is nearly fifty feet thick, and the bench is of great extent on this southerly side of the river. Crossing to the other side and taking the road over Lick mountain to Wytheville, one soon comes to a bench, 120 feet by barometer above the river or 2070 feet above tide. This was not recognized at the lead mines on the southerly side of the river, but on this side it is distinct almost from Jackson's ferry to the Wytheville road, on which it is reached at three miles from New river. The higher bench is reached by the Wytheville I'oad at six miles from the river, and, according to the barometer, is 320 feet above low water at Thorn's ferry or 2270 feet above tide. It carries a thick coat of debris loaded with pebbles. The tributary streams of New river are terraced. A fine bench was seen on Wolf creek in Giles county at a mile or so from the river. It is sixty -five feet above the stream and carries a thick deposit, which is rich in rolled stones. The upper terrace of Reed creek below Wytheville was not measured, but it is fully 150 feet above the stream. It shows huge boulders of Potsdam sandstone resting on the Knox limestone, though a broad and deep ravine separates their resting place from Lick mountain, whence they came. An erosion plane, similar to that seen in Pulaski county, was observed north from Wytheville within the New river area. Its superficial deposit of sand, often carrying many pebbles, is so thick as to conceal the bedded rocks for long distances. 1887.1 -•- ' ^ [Stevenson. Great planes of erosion are shown in all parts of the "Valley" from the Tennessee line to the eastern side of Montgomery county ; no doubt they are continuous thence into Pennsylvania, -where such planes are sufficiently distinct. At all localities they illustrate effects of erosion during a long period in which the channel-ways of the main streams are not deepening materially. By some means the erosive or channel-deepening power of the New river has been greatly increased since the erosion of the upper planes was completed ; for the river has excavated a trorge 255 to 300 feet deep with the hills abrupt on one or both sides for considerable distances ; while ero- sion extends at best to but a little way from the river. The tributary streams flow for the most part in comparatively narrow valleys, even where the conditions appear to be such as to favor extended erosion. Meanwhile the destruction of the elevated planes has gone on irregularly ; the upper bench south from Walker mountain has suffered little in Mont- gomery county except near the river. But that in Giles county has been eaten away and another, widely extended, has been formed at a lower horizon ; and there appears to be nothing south from Walker mountain to compare in extent with the lower plain north from that mountain. While the erosion of the "Great Valley" and of the region drained by New river appears easily referable to a simple plan, the conditions in the limestone area of Tazewell, Russell and Scott counties, drained by Clinch river, are not so clear. Benches exist, but they are not so obvious as are those in the valley, they do not always carry a deposit loaded with peb- bles and they seem rarely to have great extent. One gravel deposit was found on the line between Russell and Scott within a mile of Clinch river and at G40 feet above that river at Osborn's ford, making its height above tide not far from 1920 feet. The pebbles are rarely larger than a hen's egg, and are mostly quartz ; comparatively few could have been derived from the region now drained by the Clinch, and most of them must have come from the Blue Ridge or further at the south. The Clinch and North llolston are as handsomely terraced as the New river and its tributaries. The " bottom" of Clinch river appears to main- tain a uniform height of about fifteen feet above low water ; a fine terrace is shown near Osborn's ford at ninety-five feet above the river or 1375 feet above tide, and it is present on both sides of the river at a little way above the ford. A higher bench is shown on the southerly side, but its height could not be ascertained. Near Nash's ford in Russell county, three ter races are crossed as one descends to Clinch from the south. These are about 155, 40 and 15 feet above low water at the ford. The highest reaches far back from the river and its height above tide is not far from 1700 feet. A fine terrace was seen on the north fork of Holston below the mouth of Laurel creek in Smyth county, where the top of the deposit is between eighty-five and ninety feet above the river or at not far from 1625 feet above tide. The deposit on these river terraces consists of sand and clay carrying abundance of boulder, all apparently of local origin. Stevenson.] X4D [May 20, In some portions of South- west Virginia, notably in the region embracing much of North-west Tazewell county, Virginia, and of Mercer and Sum- mers counties of West Virginia, which is known as " Flat Top," there are high benches or fragmentary plains which are of considerable extent, but do not appear to carry many water-worn stones in their thin cover. They are very like the higher benches observed by the writer* in South-west Pennsylvania, and very possibly they are due to the same causes. But what these causes were is still an open question. The most natural explanation is that which regards them as erosion planes, such as were termed "base levels of erosion " by Major Powell. But in discussing these benches as they occur in Pennsylvania and adjacent States, the writer showed that as they line valleys and form irregular rings about iso- lated hills, they are merely incidental modifications of a topography due to prior and long continued erosion ; and that they are too well preserved to be regarded as fragments of great erosion planes. More than this. The deposit on these benches is marked by the absence of water-worn and rounded fragments ; the absence of such fragments cannot be accounted for by the supposition that they have been broken up by exposure, for the greater part of the deposit has been protected from atmospheric agencies ttntil exposed by the plough or in excavations for roads. The Coal Measures of Western Pennsylvania contain sandstones, whose fragments should resist disintegration eqitally with the Medina and Potsdam pebbles of South-west Virginia ; while in Bedford county of the former State, where high benches are as conspicuous as in the Coal Meas- ures counties further west, the Chemung conglomerates and the Medina sandstones are present and the stream beds are loaded with their frag- ments ; yet no rounded pebbles were seen on the benches. The absence of these boulders militates against any application of the base level process, as generally understood, and equally against the sup- position suggested by the writer, that the benches were produced by shore erosion between tides. The problem of their origin is not simplified by denying their existence, for, unfortunately, the benches are "here to stay." A ride along the National road in Pennsylvania, from Uniontown in Fayette county to Washington in Washington county, enables one to secure a key to the whole succession. Returning to Virginia. That the great erosion has occurred since the faulting took place is sufficiently shown by the contrast between the up- throw and downthrow sides of the faults ; for on one side is seen the highest portion of the Lower Carboniferous, while on the other are the lowest beds of the Knox limestones. It may be that the main streams antedated the faults and possibly the folds. The course of New river, which rises far beyond the axis of the Blue Ridge crosses at least six great faults as well as all the folds, great and small, from the Blue Ridge to the Ohio river, suggests that it may be following in a general way the original direction, *Proc. Amer. Phil. Soc, Vol. XVIII, Aug. 15th, 1879. 1887.] il* [Stevenson. Byt there have been great changes in the water- waj'S. The fragment- ary deposit on the line between Russell and Scott counties, carrying quartz pebbles at 640 feet above Clinch river, tells the story of one great change, for nothing along the upper Clinch could furnish the material for this deposit, of which so little remains. The deep erosion near the North fork of llolston river, from Saltville in Smyth county eastward for sixteen miles, cannot be referred to any present drainage system ; its bottom is more than 600 feet below the present bed of the river and the excavation has been filled with a deposit of gypsum and rock salt. This was digged out after tlie faulting, for the excavation crosses and re-crosses the Salt- ville fault.* It is sufficiently clear that the courses of many of the present streams are due in no small degree to the geological structure. The fans formed by the Clinch and llolston with their tributaries show a co-incidence with the general course of the rocks and faults which cannot be merely fortuitous. Tributaries to New river in Bland and Giles counties flow irregularly with the strike of the beds ; between outcrops of sandstone they follow the more readily yielding rocks, so that they are often brought near to the fault lines ; and many streams belonging to the other systems do the same. But in the broad limestone areas, some other cause has determined the direction, for not a few streams exist there whose courses appear to bear no relation to the geological structure. No especial weakness now exists in the immediate vicinity of the faults, for the streams flow with utter indifference to them. New river crosses all of the faults. Big Walker creek and the North fork of Holston flow back and forth over the Saltville fault, and the latter at times wanders to a distance of two or three miles, apparently without reference to the cliaracter of the rocks. Clinch river coquettes in the same way with the Clinch faults and event- ually deserts them to cross the limestone area in Scott county and to cut the Copper creek fault at ten miles toward the south-east. The North fork of Clinch crosses two faults and many of the smaller streams flow directly across one or more. It is altogether probable that the present lines of the faults are verj'^ far, in some cases at least, from the original lines. The lateral thrust in more than one case must have been enough to push the upthrowu rocks to a considerable distance over upon the downthrown series ; so that the areas of weak or crushed or much distorted roclis lay north or northwest from the lines as now observed. The crushed portions have been removed by erosion and the streams have changed their channel-ways as the erosion advanced. It is diflicult, therefore, to determine much respecting the former drainage ways. The thickness of rock removed by erosion in this region, though not equal to that removed from Western Colorado and adjacent parts of Utah, is still sufficient to challenge respect. There is no room for doubting that the Coal Measures reached at one time beyond the "Valley " to the Blue ♦See Proc. Amer. Phil. Soc, Vol. XXII, p. 15-t et seq. PROC. AMER. PHILOS. SOC. XXIV. 125. W. PRINTED JUNE 7, 1.887. Stevenson.] -L ' ^ [May 20, Ridge, for those rocks are just missed on the northerly side of the Draper Mountain fault, at twelve miles from the Blue Ridge. Even now the Coal Measures must be caught on some of the Washington county hills beyond the Saltville fault. The Lower Potsdam is brought up under the Lick Mountain anticlinal at not more than four miles from the line of the Lower Carboniferous in the Draper Mountain area. The whole of the Palseozoic column, then, or not less than 22,000 feet, has been removed from the westerly side of the Blue Ridge in South-western Virginia; while in the "Valley" and on the upthrow side of the Aiults the thickness ot removed rocks is Irom say 18,000 feet in Lick mountain to 12,000 feet or more along the faults. Additional proofs of this enormous erosion are found in the occurrence of Lower Silurian valleys separated by ridges carrying small areas of the Coal Measures. This enormous erosion occurs only on the upthrow side of the faults ; so that on the downthrow side one may find even the Coal Measures, while the lower beds of the Calciferous may be on the other. So, 15,000 feet or more may have been removed from one side, while on the other, the whole loss may not exceed 3000 or 4000 feet. This great contrast between the two sides seems to suggest that the lateral thrust was enough in every case to push tlic tqnhroicn beds far over on the downthrown, so that there could be no erosion of the latter until after removal of the former. Of course, there are perplexing problems here; they usually abound. One is suggested by the successive increase in height of the erosion planes as one ascends New river. Thus the highest south from East River moun- tain is at 1810 feet above tide ; that south from Big Walker mountain is at about 1925 feel ; while that south from Draper and Lick mountains is at about 2270 feet. These benches were all made during a long period when the river in each area had practically ceased to deepen its cliannel -way. It may be that the Medina sandstone of Draper mountain, the Chemung conglomerate and Medina sandstone of the Walker mountains and the Medina sandstone of the East River mountains may have proved sufficiently hard to resist erosion for a long time. However that may be, corrasion advanced regularly after it began, for the first bench below is reached at 140 feet south from East River mountain, at 150 feet south from the Wallier mountains, and at nearly 200 feet in the space between Lick mountain and the Blue Ridge.* A long halt in corrasion occurred during the formation of the second bench ; but thenceforward no important obstacle seems to have been en- countered and the interruptions were only long enough to admit of form- ing narrow river terraces, which usually are found on but one side of the river.

(Read before the American Philosophical Society, May 6, 1SS7.) In 1872 the Leipzig Conference propounded this question, with others, to the principal meteorologists of the ■world : "Are you of the opinion that the present state of our knowledge of the weather justifies giving definite prophecies or predictions instead of the telegraphic communication of facts, or shall we limit ourselves to intimations upon the state of the at- mosphere in the surrounding countries, from which the receivers of tlie communications may deduce their own rules?" The replies were almost uniformly in the negative, and among them that of the very distinguished meteorologist. Prof. Buys-Ballot, of Utrecht, who said : "No prophecies, if we do not want to bring this matter into discredit. It is impossible for tlie director to say on which part of the coast the wind will blow first, and be the strongest, if he does not await the be- ginning of the storm at a place at some distance, and then it is too late. Tlie state of the weather may be given. Every one may have the fixed rules by which, from this state, he may deduce his own results." And then, in a humopous way, he adds : " He who shall predict tlie weather, if he does it conscientiously and with inclination, will have no quiet life anymore, and runs great risk of becoming crazy from nervousness." The United States Signal Service Bureau has from the beginning — owing to the nature of its organization perhaps — taken a different course ; it has devoted its chief efforts to pr.edidion and signaling, while the study of nature and its laws has received but scant attention. And what is the re- sult"? Can it now give the "fixed rules," of whicli Buys-Ballot speaks, by which every one may be enabled to form some judgment of the weather? What additions to meteorological science has it ever made? Is there even one valuable result in all its voluminous literature that can- not be found in the prior works of others? If so, where and what is it? Nay, more. It has published during the last twenty j'ears a vast con- glomeration of facts and observations, at great expense of labor, intelli- gence and money, but from all this great material have any meteorologists the world over been able to make generalizations that have been accepted as sound and valuable? I think, upon reflection, we must all see that the answer cannot be affirmative, and that when the results of the Signal Service Bureau's work are summed up, it is found to be utterly disproportionate to the means at its disposal, even in the matter of prediction. Its methods must therefore be at fault. Let us examine. At the close of our civil war, upon the suggestion of the late Prof. Henry, the Telegraph Corps, whose services in the field as an active part of the army were no longer needed, was reorganized as the Signal Service Bureau, and its officers and soldiers became at one stroke, full-fledged me- teorologists, but remained under strict army discipline, and worked under Blasius.] ibU pjay 6, rigid rules. The duties assigned to them individually were, however, and still are of a very simple nature. The "observers" at the various stations, at certain hours of the day, record in tabular columns the readings of their meteorological instruments, and telegraph these to Washington ; and since my work on " Storms"* was published in 1875, in which I called especial attention to the Bureau's neglect of cloud forms, some simple observations upon the clouds are added to the telegraphic reports. Upon receipt of these reports at Washington, they are written down upon blank maps, on which the respective stations are marked. The points of lowest equal barometric pressure are then united by a line called the Isobar which usually form an ellipse. In the same way the stations of five or ten points of higher pressure are joined by a line. The field enclosed by these somewhat concentric Isobars is the "area of low pressure," or the "cyclonic storm" so called. From the results of the next reading the next position of the area of low pressure is ascertained in the same way, and by comparing the distance traveled with the time occupied, the probable position for some hours ahead is calculated, and predictions are issued. The labor is thus of a routine character "Areas of high barometer" are likewise noted, but these are thought to bring fair weather. The barometer therefore is still the chief reliance in the prediction of storms, and those storms which are distinguished as "areas of low pressure" are practically all that the Signal Service is able to predict. Now, in the report of the Chief Signal Officer for 1884, there are noted as having occurred during the year 152 of these areas of low pressure, 172 tornadoes, 947 hailstorms, and 1745 thunder-storms, so that if every one of the 152 "cyclonic storms" — the "areas of low pressure" — are correctly predicted, we have some 2864 storms, of which the Bureau knew nothing until after they had occurred. Relying on the barometer and on machine methods, it could not be otherwise. Lieut. J. P. Finley, Chief of the Tornado Division of the Bureau, in "Signal Service Notes, No. XII," says: "Probably if a barometer were placed in the immediate track of a tornado cloud, it would not with any certainty indicate the presence of the storm until the crushing winds had fallen on the instrument." Indeed, although the Bureau appears to pro- ceed on the old rule that has obtained predominance since the daj'sof Otto von Guericke, that a falling barometer denotes an approaching storm, it has long been well known that the most destructive storms often arrive with a rising barometer, and this for reasons that I explained as long ago as 1852. One of these storms took place at Colon, or Aspinwall, Panama, December 2, 1885. The New York Herald of December 18 says : "This storm was not preceded by any distinct precursory signs. The barometer on the Isthmus apparently remained stationary or slowly rose during the progress of the tempest. Much property, many vessels and lives were lost." * Storms : Their Nature, Classification and La-\ys. Porter & Coates, Philadelphia, 1875. 1887.] 1"! [Blasius. One of the most destructive storms this country has ever witnessed, occurred on the coasts of Nova Scotia and Newfoundland, August 28, 24and 25, 1873, by which about 500 lives were lost and 1032 vessels destroyed, including 435 small fishing schooners. The Signal Service Bureau was entirely taken aback by this storm, because an "area of high pressure" or an "anticyclone" had been moving from Manitoba to the coast, and therefore, fair weather was to be expected. But in the weather maps for several days previous could be traced the gradual advance of a wave of cold air from the North — the "area of high pressure" — which banking up the warmer air in its front as shown by the gradually rising gradient, finally culminated in a terrific south-east storm with its centre of destruction on the coast. We thus have a storm of the most violent character traced on the maps of the Signal Service Bureau for several days as a fair weather indicator. The Chief Signal Oflicer reports 80 "areas of high barometer" during 1884. Those occurring in the cold season mean fair weather, as they dis- place the warm current which has previously discharged its moisture. In the summer, however, this cool air from the North, which being heavy can be identified as an " area of high pressure, " causes — in its displacement of the then prevailing warm and moist air — tlie south-east storm, with its tornadoes, hail-storms, cloud-bursts and thunder-storms, none of which the Signal Service Bureau predicts, and which cause vastly more destruc- tion than the north-east storms — the "areas of low pressure" — both from their greater violence, and because they mostly occur at a season of the year when the work of the agriculturist is going on and his crops — on which the nation depends for its prosperity — are subject to injur^^ It is true that quite lately the Bureau has turned its attention to this brancli of the subject, after so many years of practical neglect, and that claims of considerable magnitude have been advanced as to what has been accomplished and what will be accomplished, both in the way of predic- tion and scientific discovery. Let us therefore examine into this a little. The most eminent of American meteorologists — Redfield, Espy and others— agree in thinking the tornado the most instructive of all storms. It is in some respects the type of our American storms, since here the op- position of air-currents of different temperature and density, which is the general cause of storms, is most strikingly manifested and within the nar- rowest limits. Mr. Wm. A. Eddy, an attache of the Bureau, in The Popular Science Monthly tor January, 188G, says: "During the first part of 1884, the United States Signal Service began to pay special attention to the question of tornado prediction. Tlie development of the science was rapid under the active supervision of Lieutenant .John P. Finley, having charge of that department of the service. It was found that the public interest in the question was widespread, and that with the aid of voluntary reporters of tornado phenomena, the possibility of saving life and property had begun to crystallize into a practical scheme." He furtlier says: "During the Blasius.l -l-O-^ [MayC, summer of 1886, it is hoped that, by means of signals, hundreds of lives and much valuable property will be saved." The summer of 1886 has passed ; can it be said that this hope is realized ? Has the Signal Service saved a single life or any property by its tornado predictions? Mr. Eddy tells us that the "invariable location south-east of the storm- centre is one of the main peculiarities of tornado development upon which the predictions depend." And yet to this same peculiarity, with its expla- nation, I called attention as earlj^ as 1852, and again in 1875, in the pub- lication of my work on storms already referred to, and I urged it on the Signal Service Bureau during a personal visit to Washington at that time. Mr. Eddy also says: "When the conditions are unfavorable for the development of tornadoes, there are no unusual contrasts of tempera- ture, the areas of warm and cold air neither great nor well defined north- ward and southward, the winds are variable and not very strong, and the distribution of pressure is about normal." All this can be found in my work on "Storms," published in 1875 — why is it put forward as a new discovery in 1886 1 Indeed, it was only after the publication of that work that the Signal Ser- vice Bureau began to note the difference of temperature in air-currents — to which I had called attention — and made various and important changes in its method of prediction. But when Lieutenant Finley puts forth as a discovery of his own, the fact that tornadoes are caused by "two opposing air-currents of different temperatures and moisture," it seems a little sin- gular, in view of my communication of the same fact to the Academy of Science in Boston, in 1851, its publication in 1852, and again, in 1875. As to the prediction of tornadoes by the Signal Service, it can never be done with any certainty, except in so general a waj^ as to be valueless. If any one has mastered the principles of atmospheric disturbance — and they are not so difficult — he will be able to judge for himself as to the probability of tornadoes being imminent in his locality ten times as well as the Signal Service can ever tell him. Just where the tornado will strike, and its path is a narrow one, no man can tell until within a few minutes of its passage. Mr. Eddy says: "That during 1884, 3228 predictions ■?^^?ifavorable to tornadoes were made, and of these 3201 were verified." But what a sim- ple matter it is with the most ordinary knowledge and circumspection to say that tornadoes will not take place, when the dark clouds of the south- east storm give ample notice when there is a possibility of their happen- ing? If we have a southeast storm we may or may not have tornadoes ; but if we have 7iot a south-east storm, then we have no tornadoes. As to the prediction of a tornado itself, jNIr. Eddy cites that which passed over Camden and Philadelphia, August 3, 1885, as " one of the best illustrations of the advance made in definiteness in predictions ;" and he further says : "The chart used by Lieutenant Finley shows that torna- does were predicted and their location marked upon the map for the State 1887.1 loO [Blasliis. of Delaware, South-eastern Pennsylvania and for New Jersey. The tor- nadoes actually occurred in these States, about eight hours from the time of prediction." Now if we ask how valuable to the owners of the houses damaged by that tornado in Philadelphia was the Signal Service's prediction eight hours before, that tornadoes would occur somewhere in " Delaware, South-eastern Pennsylvania or New /ersey, " we cannot fail to see, I think, the entire impracticability of the whole scheme. The Signal Service is perhaps obliged by circumstances to devote most attention to those things which will show most apparent results to the general public and to Congressmen who vote for the annual appropriation. It is hampered too by its routine methods and its army rigidity of disci- pline. It cannot however but be a cause of disappointment that whether owing to these causes or others, it has added so little of scientific value to the knowledge of meteorology during the twenty years of its existence. It has been following the old methods in reference to which Sir William Ilerschel says : " In endeavoring to interpret the weather, we are in the position of a man who laears, at intervals, a few fragments of a long his- torj^ related in a prosy, unmethodical manner ; a host of circumstances omitted or forgotten, and tlie want of connection between the parts pre- vents the hearer from obtaining possession of the entire story." And the great Biot, after enumerating the efforts to advance this science, says : " What has come of it? Nothing, and nothing will ever come of it. No single branch of science has ever been fruitfully explored in this way." No, the methods followed have been wrong. Would astronomy be in its present position if the great astronomers had been dependent on the data furnished by ol)servations made according to arbitrary rules, and for a minimum of time at one or two hours of the night, and for the most part, too, by observers of meagre training and intelligence? And how much would the great naturalists have learned, liad they been content to send out into the fields three times a day for five minutes, and sit in their closets to generalize upon the data thus obtained ? Tliirty five years ago, I urged that only by continuous observations could we hope for anything beyond mere empirical knowledge ; that we must gather up the "host of circumstances " now "omitted or forgotten," and supply "the connection between tho parts."' I am not unmindful of the practical difficulties that are in the way of a method of observation that alone can give a continuous knowledge of a storm as it passes ; but it seems to me that this may be obtained with the means now available, if the meteorological organization would devote more attention to the dis- covery of general laws than to the more sensational part of their duties — the weather predictions, which the newspapers now make a matter of busi- ness enterprise. If we know the laws, there will be little trouble about the prediction. Each of us can do this for himself sufficiently well for all practical purposes. i-o4: [Dec. 17, Stated Meeting^ December 17^ 1886. Present, 39 members. President, Mr. Fraley, in the Chair.

A Contribution to the History of the Vertehrata of the Trias of North America. By E. D. Cope. [Read before the Americnn Philosophical Society, April 15, 1S87.) The vertebrata of the Trias of North America are not as yet well known, and scarcely twenty species have been describecl. Those known to the writer in 1870 are enumerated in the Transactions of this Society, Vol. xiv ; and the species discovered in Pennsylvania are catalogued in the Proceedings of this Society for 1886, p. 403. Some species from New Mexico are described in the American Naturalist, 1881, p. 922,* and April, 1887. Descriptions of several forms from this formation, from the Rocky Mountain region, with plates, were given in the Report of the U. S. Oeol. Geogr. Survey W. of the 100th Meridian, 1877. I am now able to add descriptions of some new species from New Mex- ico ; and furnish additional characters of species already described. 1. EuPELOR DURUS Cope. Transac. Amer. Philos. Soc, 1869, p. 25, V. xiv. A good many fragments of this species or one nearly allied to it were obtained by Mr. C. M. Wheatley, in York county, Pennsylvania. These pieces are not all as yet identifiable, but one of them consists of a large part of the ramus of the lower jaw which supports the bases of the pos- terior teeth, but from which the cotyles and angles have been broken off. The bases of the teeth are cylindric, and show delicate grooves, being similar to those of Eryops, and proving that my original reference of teeth to this genus was probably correct. All the bones show the coarse honeycomb pattern of sculpture of the external surfaces characteristic of the species. Towards the margins of the bones the pits become confluent into radiating grooves.

Ttpothorax coccinarum Cope. U. S. G. G. Survey W. of 100th Me- ridian, Capt. G. M. "Wheeler, 1877, iv, Pt. ii, p. 30. PI. xxii, figs. 4, 5 and 9. American Naturalist, 1887, p. 468. The genus Typothorax was distinguished by me, 1. c, from Belodon, on account of the regularly pitted surface of the dermal bones. With such dermal bones others of a different character were found, which it was thought best to refer to the same genus, and a fragment of maxillary bone found near by was included in the description. I now suspect that the dermal bones which do not possess the pitted character belong to some other reptile, and the fragment of jaw is not to be referred, certainly, to the TypotJiorax coccinarum, but is more likely a part of a Belodont Saurian. The additional material belonging to this geuus and species which I possess consists of two ribs with corresponding dermal bones attached to their superior surfaces, and two femora, one of which adheres to one of the ribs. Also several other more or less incomplete dermal bones. There are numerous other bones accompanying, but their reference is not cer- tain. Char. Gen. The peculiarities of this genus as displayed by these speci- mens are as follows : Ribs greatly expanded but with free margins, each overlaid by a band-like dermal bone for its entire length. The dermal bones with pitted sculpture and straight, simple margins, the one acute and the other obtuse. The margins of the ribs are similar to each otherl It results that a gaping groove is formed between the parallel acute edge of the dermal plate and the rib into which the appressed edges of the adjacent rib and plate enter and fit. Thus is formed a complete cuirass covering the body. Femur sigmoid, without distinct head or trochanters, excepting a prominent, ridge-like third trochanter on the posterior face. Condyles with a posterior lobe separated from the external lobe by a fossa. It is possible that one of the ribs described is abdominal in position, as it does not appear to have had a head. There is no head preserved on the other. The dermal bands described may be therefore abdominal. The ribs are, however, strongly curved in the longitudinal direction, and it is to be supposed on this account that they are dorsal, and perhaps in the position of flying ribs. The adhesion of a femur to one of them indicates posterior position. The character of the femur is different from that of the BelodontidfB in its trilobate condyles, approaching thus the Goniopod Dinosauria. The third trochanter is much better developed than in any known Belodont.* * Von Meyer Paleeontographica, vii, 1861. 1887.] -^11 [Cope. Future comparison must be bad witb the genus Aetosaurus Fraas,* which accompanies Belodon in the Upper Keuper of Wurtemberg. That genus is encased in parallelogrammic scuta arranged in contiguous cross-bands, on both surfaces of the body. But the scuta are not co-extensive with tlie ribs as in Typotliorax ; at least tlie latter are represented by Fraas as much narrower than the osseous dermal bands. The latter are also trans, versely subdivided in Aetosaurus. It is highly probable, however, that Typothorax represent Aetosaurus in the Upper Trias of North America, and may belong to the same family of the order Rhynchocephalia. The relations of the dermal bones and ribs are highly interesting. The great expansion of the latter needs but the development of sutural sur- fivces on their borders to produce an osseous continuum. The same modi- fication of the dermal bones above it would form a second external roof. A subsequent fusion of the superior and inferior roofs would give us the testudinate carapace. And this history would be what embryology teaches us is the origin of that remarkable modification of the dermal and true skeleton exhibited by that order of reptiles. It is probable that Typo- thorax is nearly allied to the type from which the order of tortoises has been derived. It is unfortunate that we know nothing of its skull and vertebrae, but there is nothing in the characters of the femora to preclude the above hypothesis. They belong to a type which progressed in a prone position, and which probably differed much from both Belodonts and other Dinosauria. Char. Specif. Ribs strongly convex in the longitudinal direction ; in the transverse direction flat above, and with a longitudinal convexity below. This convexity occupies about one-third of the inferior surface, and ex- tends obliquely to one of the lateral borders at the extremity. At the other extremity the surface is flat, the rib-convexity disappearing. la both ribs one edge is subacute and the other obtuse. The rib-thickening runs out to the thin edge. The dermal scuta have the same width as the ribs. They have thicker and thinner edges corresponding with those of the ribs. Where the rib-thickening of the latter is prominent, the dermal bone has a median convexity below ; and this disappears at the other end as the thickening does from the rib. The superior face of the dermal bones is perfectly flat. It is sculptured with coarse shallow pits, separated by obtuse ridges, which have a reticulate pattern, since the pits are not in rows. These osseous bands are probably in contact, thus forming an impene- trable buckler, as in Aetosaurus. One edge of the osseous combination of rib and dermal plate gapes, the thin edges of the two elements diverg- ing so as to receive the margin of the adjacent band. The matrix along this border is clearly impressed so as to prove the former presence of the succeeding portion of the carapace. * Aetosaurus ferraius Fraas ; Festschrift zur Feier d. vierliundertjahrigeii Jubiliiums Univ.

They are : Two caudal vertebrii?, a proximal and a distal ; a humerus ; two ulnre ; a femur lacking the condyles ; a prox- imal part of a tibia ; the distal part of a fibula ; a calcaneum, and a num- ber of dermal bones. The only part of the skull possibly belonging to this animal is a splenial bone. Char. Oen. The generic characters, so for as ascertainable from the materials, resemble those of Belodon with certain exceptions. Chief among the latter is the disproportion, in dimensions, between the ante- rior and posterior extremities, which is as great as that existing in many Dinosauria proper. Appropriately to this relation, the femur diflers from that of Belodon in the absence of curvature of the shaft, having the straight form of that of most Dinosauria proper. There are no trochanters of any kind on this femur, and its head has the wedge-shaped Belodon outline. The head and condyles of the humerus are transversely ex- panded ; the shaft is contracted ; condyles not specialized. No epicondylar foramina of either side, but a strong ectepicondylar groove, which cuts off a narrow ectepicondylar ridge, which terminates freely. The caudal vertebne are elongate, indicating a powerful tail. But one species is yet known. Char. Specif. The body of the anterior caudal vertebra has a wedge- shaped section, the apex inferior, representing the section of an obtuse median keel. The articular faces are subcircular, widening upwards. Both are concave, the posterior more so than the anterior, which is nearly plane. No lateral ridges on the body. Arch lost. The posterior caudal is long and slender, and has a long compressed neural arch. The section of the body is heptagonal, as there are two low lateral angles on each side, and an obtuse median inferior keel. The inferior lateral angle is stronger than the superior.

Viewed in profile it is strongly convex, the convexity being a little nearer the internal than the external extremity. The articular surface descends on the inner edge of the bone towards but not to the bicipital crest. Viewed proximally, the convexity of the head is as wide as the inner extremity, and is distinguished from it by a concavity of the inner side. The bicipital crest is the incurved external border. It commences opposite the prominence of the inner extremity of the head, and extends but a short distance down the shaft. It is quite prominent. The face of the bone below the head displays a very shallow concavity. The posterior face is recurved towards the two margins, as we approach them. The shaft is very much contracted. Its section at the middle is a wide oval ; the external edge subacute, the internal broadly rounded. The distal extremity is much expanded, though not so widely as the proximal end. The expansion is greater internally than externally. Neither epicondylar prominence, however, extends much beyond the articular surface. The latter is rather narrow, and is curved, the concavity anterior. The two extremities are wider than the middle region, the external part being the widest. There is a deep groove on the posterior face near the external edge, which runs out, leaving the external epicondylar process to terminate at about 20 mm. proximad of the condyle. The latter terminates outwards in an acute angle, which marks the internal edge of the ectepicondylar groove. The epitroclear fossa is well defined. Posterior face plane. Measurements of Immerus. M.

A well -developed obtuse ridge, above the middle of the shaft on the posterior face, represents the tliird trochanter. The head occupies the entire proximal extremity.

The simplest form is oval-parallelogrammic, with a low obtuse median keel, which rises at one extremity into a moderately compressed knob. 1887.] 217 fCope. which terminates abruptly. Shallow grooves separated by ridges radiate from this prominence in all directions. On its sides the sculpture becomes smaller and more irregular. In the second type of bone, the median keel is elevated into a crest which extends the entire length, and cannot be distinguished at any point as a knob. The section of such a bone is tri- radiate, and it is not always practicable to state which of the three laminte is the free one. In any case the latter is not median on the fixed portion. In the third type of dermal bone, the free keel is much developed and rises into a tuberosity so produced as to be a well-developed spine. The inferior surface of the bone is longitudinally concave. The section of the spine is triangular, the apex being the sharp edge which is the con- tinuation of the keel. The sharpness of this edge is such as to render it probable that these spines constituted dangerous weapons of defense. One side of the spine is nearly vertically over the edge of the base, while the other is within the other edge. The surface of the bone is perfectly smooth. None of the dermal scuta of Belodon described by Von Meyer are developed into spines like those of this species. Measurements of dermal hones. No. 1. :m. -r,. , (anteroposterior 100 Diameters \ ^ „„.

Some years ago* I identified certain fossils discovered in North Carolina by Emmons as Belodous ; and later.f referred a species found by Wheat- ley in Pennsylvania to the same genus. I was subsequently able to prove that the genus ranged over the Rocky mountains, and that there, as in other parts of the world, it haunted the shores of the Triassic seas and lakes. There are two species of Belodon in my New Mexican collections, * Proceedings of Academy of Natural Sciences, Pliiladelphia, 1866. t Transactions Amer. Philos. Soc, xiv, 1869. PROC. AMER. PHILOS.

In the former the muzzle is keeled above, and rises into a crest in front of the nares. In the other species the muzzle is subcylindric, and does not rise anterior to the septum of the nostrils. The larger species I call Belodon buceros ; the smaller one B. scolojxix, and define them below. Bones of the skeleton and of the dermal systems of this genus are common in the New Mexican beds, but I am yet unable to refer them positively to the species repre- sented by the skulls. C7iar. Specif. Size of the gavial. Muzzle slender, compressed, with a narrow median superior ridge, rising at the middle of the length into a compressed crest, whose summit is in the plane of the frontal region. Nostrils a little further anterior to the orbits than the diameter of the lat- ter, longer than wide, and separated by a thin septum. Orbits round, looking a little upwards, the interorbital region a little narrower than each orbit. Preorbital region compressed ; preorbital foramen large, in- ferior. The quadrate bones are directed forwards, and then downwards, and tlieir articular faces are in the transverse line of the two rather narrow notches of the posterior outline of the parietal bone. The auricular meatus is bounded posteriorly by a descending hook-like process ; and the squamosal bone is continued still further posteriorly into a short triangular acute horn. The superior surface of this bone, with the parietal and frontal, are roughened with tubercles. The palate has a strong ridge on each side, so as to be grooved. The posterior teeth have compressed denticulate crowns. Tip of muzzle lost.

This species is of the size of the B. kapfl Meyer, and is, in the form of the muzzle, intermediate between that species and the B. plieningeri. Foramina. The alisphenoid bones embrace the olfactory lobes of the brain as far forwards as the middle of the orbits, when they contract to a foramen of moderate size. The under face of the median line of the frontal bones is openly grooved in continuation. The basioccipital has a horizontal axis, and is about as long as wide, including the condyle. Its anterior border has a median apex or proj ection on the sphenoid. The latter forms a transverse band of small anteroposterior diameter to a sharp trans- verse truncation or anterior border. Whether this is the boundary of this element or not is uncertain. It is probably merely a transverse crest, since in front of it the basicranial axis is continued. The latter is deeply concave in the middle, but sends downwards a process on each side, which fits into a notch of the posterior internal border of the pterygoids. Between these notches the pterygoids underroof the axis, and unite on the median line. This union has a less anteroposterior extent than is represented by 1887.] ^^'^ [Cope. Von Meyer in the B. kapfi,- and the posterior nostrils, which commence in front of this union, have a much greater anteroposterior extent than in that species. There is a fossa in the posterior part of the orbit which extends down- wards and forwards. In the superior part of its fundus is the mouth of a canal which extends from the pineal fossa of the brain case. I call this the orbito-pineal canal. It will be again referred to in the description of the brain. Below the anterior part of this fossa, and at the base of the closed interorbital part of the brain-case, is the large optic foramen. It looks outwards and forwards, and it is not certain that it is separated from that of the other side by a septum. The lateral walls of the brain-case are imperforate. There is no foramen for the trigeminus in the usual posi- tion. A portion of the superior face of the sphenoid bone is split away, and it may be supposed that the trigeminal foramen was at the base of the brain on the line Avhere the lost portion joined the lateral walls. It must have been of small size. A canal traverses the basioccipitalbone on each side, commencing in conjunction with that of the opposite side, and ex- tending outwards and backwards, and issuing on the suture joining the basi- and exoccipital bones. Brain. The cast of the brain-case presents several peculiarities of im- portance. The size is a little greater than that of an Alligator mississippiensis Avhose skull slightly exceeds that of the Belodon buceros. Thus the dimen- sions of the former are, length 500 mm., width at quadrates 290 mm.; of the B. buceros, length 700 mm., width 240 mm. The distribution of parts is different. The prosencephalon is relatively and absolutely smaller in the Belodon, and the mesencephalon is larger. The epencephalon is not very different in the two, and the contraction on each side of it is apparent in the one as in the other. Posterior to it, the medulla is contracted to a still smaller diameter in a manner not seen in the alligator. This region is longer in the Belodon than in the latter. The brain proper is thus bunched up or shorter and more elevated in the Belodon than in the alli- gator. The contraction to the rhinencephalon is more abrupt in the Belo- don. What gives the Belodon its especial character is the presence of an enormous epiphysis. Tliis body is subquadrale in form, and occupies a large fossa in the cranial roof, which is, however, not perforate. On each side of the anterior portion a process extends outwards and forwards, occupying a corresponding anteroposterior fossa in the cranial walls. The process is continued, horn -like, on each side, and the cast forms a continuum through the orbitopiueal canal to the orbit. Whether this represents a nervous or arterial canal can only be surmised, but from the size of the process of the epiphysis which enters it, I suspect that a nerve formed part of its contents. There is no median distinction between the halves of the prosencephalon and mesencephalon in tlie brain-case, thus resem- bling other crocodiles. The mesencephalic bodies were probably lateral, judging from the greater width of the cast below at the middle, as com- * Palffiontographica, Vol. viii. Cope.] ^^^ [April 15, pared with the contraction of the part behind the epiphysis. The hypoph- ysis is distinct but not large, and occupies a fossa of the base of the cranial cavity, very much shorter than that possessed by the Alligator viississippiensis. The optic nerves issue immediately above and anterior to it. Comparison with the brain of Diadectes. In these Proceedings for 1885, p. 234, I have described a cast of the brain- chamber of a species of the Diadectidse from the Permian bed of Texas. As a successor of the Dia- dectes, and as descendent of probably one of the Clepsydropidfe, consider- able interest attaches to a comparison of the brain of Belodon with it. The first point which arrests the attention in making the comparison, is the similarly huge size of the epiphysis in the two types. A foramen on each side of the base of the epiphysis in the Diadectes gave exit to a pro- cess similar to that which enters the orbitopineal canal in the Belodon, and which I called the lateral process of the epiphysis in the latter. (Plate, figs. 1-3, 1 0- The processes are probably homologous in the two genera, but In the Diadectes they did not extend to the orbit, unless they were continued in membranous walls. There is little resemblance between the two brains in other respects, but they agree in the small size of the pros- encephalon, and in the complete enclosure of the rhineucephalon by osseous walls. In the Diadectes there is no optic foramen, but a huge trigeminus ; in Belodon, an optic foramen, and a very small trigeminus. The presence of such a huge epiphysis in the Belodon as compared with its very small size in modern crocodiles, is a point of much interest, and points to its inheritance from the reptiles of the Permian. Bat if, as is probable, it contained the pineal eye, the latter could not receive light directly from above, since the parietal foramen is wanting. The presence of a communication with the orbit becomes interesting in this connection. A minute foramen passes from the base of the rhineucephalon into the orbit in the alligator, but the homology with the canalis orbitopinealis is by no means made out. The nervus orbitopinealis may have supplied the lack of light due to the closure of the parietal foramen, but in what way we are left to conjecture. The equality of size of the brain of the Belodon to that of the existing alligator is a point of interest. There is some reason to suspect that the Diadectes relied exclusively on the pineal eye for the sense of sight. The species of the family were probably subterranean in their habits, since their humeri indicate great fossorial power, resembling those of the existing monotremes, and even the mole. The vertebra are locked together with the hyposphen beside the usual articulations, and the arches of the neural canal form an uninterrupted roof from the skull to the tail, of extraordinary thickness and strength. That the species were not aquatic is rendered probable by the fact that the orbits do not look upwards. Their superior borders are, on the contrary, prominent and straight. Add to this fact the apparent 18S-.] 221 fCope absence of optic foramina, and the probaljility that the Diadectidte were blind and subterranean in their liabits becomes great. 5. Belodon scolopax Cope. American Naturalist, 1881, p. 923. This species is represented by a snout, which includes the anterior bor- der of the nares ; it is broken into five pieces, 'which should be connected with intermediate fragments, which are lost. This muzzle is a little shorter than that of B. pUeningeri, but is a good deal more slender, the distal part having only half the diameter of the latter. Besides this char- acter, it differs from that of B. iHieningeri in three others. The extremity of the muzzle is not so much decurved. All the alveohe have a more lateral exposure, and the lateral ridges of the palate are thus more dis- tinctly seen from the side. The two teeth on the extremity of the muzzle are closely crowded together, and their large alveohv are scarcely distinct. The surface of the muzzle is distantly and weakly grooved and punc- tate.

Numerous fragments of this genus are in my collection from the Triassic beds of New Mexico. The vertebnie resemble in various essential characters those which are preserved and described by I\Iarsh as belong- ing to the species of his genus Coelurus, and I therefore referred the present species to that genus, as above cited. It is now clear to me that the Triassic species must be distinguished from Ccelurus. Prof. Marsh states that the anterior cervical vertebra of the latter have the anterior articular surfaces convex, while the posterior are concave. In the Triassic species the third cervical is concave at both extremities, thus resembling the posterior centra. In searching for a name for the Triassic genus, I find that the Tanystrophieus of Von Meyer will probably include the American species iu question. This genus was established on caudal vertebroe which nearly resemble those of the New Mexican species. For the present then I will retain for them the generic name first given to the Tanystrojyhmus conspicuus of the Trias of Wiirteniberg. The bones in my possession are from all parts of the skeleton, excepting jaws and teeth ; fragments of skull, if present, are not yet determinable. These show that Tanystrophiuus with Ca?lurus,* must be referred to a family of the carnivorous suborder (Goniopoda) of the order Dinosauria. The acetabulum is widely perforate, its pubic and ischiadic processes being widely separated from each other. The pubis has a slender shaft directed downwards, as in Oompsognathus, and in Creosaurusf as figured by Marsh, with an anteroposterior expansion proximally, but no sym- physis distally. On the other hand the ischia have a symphysis. The * Amer. Journal Sci. Arts, p. 339, Plate x. t Amer. Journal Sci.

I cannot therefore agree with Prof. Marsh that Ccelurus cannot be referred to any known order.:]: It is in fact allied to Megadactylus (Hitchcock) from the Trias of 3Iassachusetts, differing principally, so far as determinable, in the form of the condyles of the femur. They are simple in Ccelurus, but in Megadactylus, the external condyle has the double character seen in Megalosaurus.* The vertebrae are all of slender proportions, especially those of the neck and tail. These, with most of the bones of the limbs, are hollow, having large central cavities surrounded by thin walls, as in Megadactylus. The parapophyses are confined to the anterior parts of the centrum. In the cervical and dorsal vertebrae there is a conical fossa at eacli base of the neurapophj^sis, which unite by their apices in the cervicals, forming a canal distinct from that for the vertebral artery. The zygapophyses are partly interlocking, having convexo-concave oblique articular surfaces. There are four vertebrte of the sacrum (in T. bauri), whose arches are coossified as well as the centra. The anterior caudal vertebrae only have chevron bones. Prof. Marsh says they are wanting in the genus Ccelurus ; but he does not appear to have possessed the most anterior of the series. In neither species is there a distinct third trochanter of the femur ; but there is not far below the great trochanter on the anterior face, a low longitudinal, ridge-like angle. The femoral condyles have but little antero- posterior extent, which implies but little flexure of the knee. The form seems to have been that of a terrestrial reptile which walked readily on the hind legs, and was probably a great leaper. Tlie ex- tremely long neck is a striking peculiarity, having proportions to the body about like that of the swan. The habits were probably predaceous and carnivorous.

The proximal end is fan-shaped, the expansion from the axis being posterior. The proximal extremity is narrow, but is widest anteriorly, and displays three surfaces. The anterior one is for the ilium, the middle one is part of the acetabular border, and the poste- rior and narrowest is for the ischium. The foramen for the internal fem- oral artery is below the acetabular portion. The anterior border of the pubis to the extremity is rib-like, while the posterior is laminiform. The internal lamina is continued from the antero-internal face, and forms a con- cavity with the postero-exterual. Its exact width is not determinable for a good part of the length, for owing to its tenuity its edge is broken off. The distal extremity does not appear to have been united to that of the other side ; if it was it could only have been by the laminar edge. The extremity is something like the head of a crocodile's humerus, the laminar edge terminating in the usual position of a deltoid crest. The shaft of the pubis is nearly straight.

Brinton^ 3I.D. {Read before the American PhilosopJiical Society, Sept. 2, 1S87.) In the first edition of my Myths of the New World,* published in 1868, 1 asserted that the story of the city of Tula and its inhabitants, the Toltecs, as currently related in ancient Mexican history, is a myth, and not history. This opinion 1 have since repeated in various publications,t but writers on pre-Columbian American civilization have been very imwilling to give up their Toltecs, and here lately M. Charnay has composed a laborious monograph to defend them.| Let me state the question squarely. The orthodox opinion is that the Toltecs, coming from the north (-west or -east), founded the cit}"- of Tula (about forty miles north of the present city of Mexico) in the sixth century A.D. ; that their State flourished for about five hundred years, until it numbered nearly four millions of inhabitants, and extended its sway from ocean to ocean over the whole of Cen- tral Mexico ; § that it reached a remarkably high stnge of culture in the arts ; that in the tenth or eleventh century it was almost totally destroj^ed by war and famine ; || and that its fragments, * Myths of the New World. By D. G. Brinton. Chap, vi, passim. t Especially in American Hero Myths, a Study in the Native Religions of the Western Con- tinent, pp. 35, 64, 82, etc. (Philadelphia, 1882). X M. Charnay, in his essay. La Civilisation Tolteqm, published in the Sevue d'Ethno- graphie, Tome iv, p. 281, 1885, states his thesis as follows: "Jo veux prouver I'existence du Tolti^qne que certains ont uii'e ; je veux prouver que les civilisations Americaines ne sont qu'une seule et mome civilisation ; enfin, je veux prouver que cettc civilisation est toltC'que." I consider each of these statements an utcer error. In his Anciames Villes d?t Nouveau Monde, >!. Charnay has gone so far as to give a map showing the migrations of the ancient Toltecs. As a translation of this work, with this map, has recently been published in this country, it appears to me the more needful that the baseless character of the Toltec legend be di.stiiictly stated. § Ixtlilxochitl, in his Jiclariones Historicas {in Lord Kingsborough's Antiquities of Mexico, Vol. ix, p. 333), says that during the reign of Topiltzin, liist king of Tula, the Toltec sovereignty extended a thousand leagues from north to south and eight hundred from east to west ; and in the wars that attended its downfall five million six hundred thousand persons were slain ! ! II Sahagun (Hist, de la Nuet^a Fspaiia, Lib. viii, cap. 5) places the destruction of Tula in the year 319 B. C. ; Ixtlilxochitl (Historia Chichmera, iii, cap. 4) ))rings it down to 969 A. D. ; the Codex Ramirez (p. 25) to 1168 ; and so on. There is an equal variation about the date of founding the city. Brinton.] ^dU [Sept. 2, escaping in sepai'ate colonies, carried the civilization of Tula to the south, to Tabasco (Palenque), Yucatan, Guatemala and Nicaragua. Quetzalcoatl, the last ruler of Tula, himself went to the south-east, and reappears in Yucatan as the culture-hero Cukulkan, the traditional founder of the Maya civilization. This, I say, is the current opinion about the Toltecs. It is found in the works of Ixtlilxochitl, Veitia, Clavigero, Prescott, Brasseur de Bourbourg, Orozco y Berra, and scores of other reputable writers. The dispersion of the Toltecs has been oflFered as the easy solution of the origin of the civilization not only of Central America, but of New Mexico and the Missis- sippi valley. * The opinion that I oppose to this, and which I hope to estab- lish in this article, is as follows : Tula was merely one of the towns built and occupied by that tribe of the Nahuas known as Azfeca or 3Iexica, 'whose tribal god was Huitzilopochtli, and who finally settled at Mexico-Tenochti- tlan (the present city of Mexico) ; its inhabitants were called Toltecs, but there was never any such distinct tribe or nation- ality ; they were merely the ancestors of this branch of the Azteca, and when Tula was destroyed by civil and foreign wars, these survivors removed to the valley of Mexico and became merged with their kindred; they enjoyed no supremacy, either in power or in the arts*; and the Toltec " empire " is a baseless fable. What gave them their singular fame in later legend was partly the tendency of the human mind to glorify the " good old times " and to merge ancestors into divinities, and especially the significance of the name Tula, " the Place of the Sun," lead- ing to the confoimding and identification of a half-forgotten legend with the ever-living light-and-darkness myth of the gods Quetzalcoatl and Tezcatlipoca. To support this view, let us inquire what we know about Tula as an historic site. Its location is on one of the great ancient trails leading from *Since writing the above I have received from the Comte de Chareneey a reprint of his article on Xibalba, in which he sets forth the theory of the late M. L. Angrand, that all ancient American civilization was due to two "currents" of Toltecs, the western, straight-headetl Toltecs, who entered Anahuac by land from the north-west, and the eastern, flat-headed Toltecs, who came 1)y sea from Florida. It is to criticise such vague theorizing that I have written this paper. 1887.] Zoi [Brinton. the north into the Valley of Mexico.* The rnins of the old town are upon an elevation about 100 feet in height, whose summit presents a level surface in the shape of an irregular triangle some 800 3'ards long, with a central width of 300 yards, the apex to the south-east, where the face of the hill is fortified by a rough stone wall.f It is a natural hill, overlooking a small muddy creek, called the Eio de Tula.X Yet this unpretending mound is the celebrated CoalepetJ, Serpent-Mount, or Snake- Hill, famous in Nahuatl legend, and the central figure in all the wonderful stories about the Toltecs.§ The remains of the arti- ficial tumuli and walls, which are abundantly scattered over the summit, show that, like the pueblos of New Mexico, they were built of large sun-baked bricks mingled with stones, rough or trimmed, and both walls and floors were laid in a firm cement, which was usually painted of different colors. Hence probablj^ the name PaZ/:)an, " amid the colors," which tradition says was applied to these structures on the Coatepetl.|| The stone-work, * Motolinia, in his Histnria de los Indios de Nucva Espana, p. 5, calls the locality " el Puerto llamado Tollan," the pass or gate called ToUan. Through it, he states, passed first the Colhua and later the Mexica, though he adds that some maintain these were tlie same people. In fact, Colhua is a form of a word which mekns "ancestors;" colli, forefather, no-col-hiian, my forefathers, Colhuacan, "the place of the forefathers," where they lived. In Aztec picture-writing this is represented hy a hill with a bent top, ou the "ikonomatic" system, the verb colna, meaning to bend, to stoop. Those Mexica who said the Colhua preceded them at Tula, simply meant that their own ancestors dwelt there. The Analei^ de Cuaufitillan (pp. 29, 33) distinctly states that what Toltecs survived the wars which drove them southward became merged in the Colhuas. As these wars largely arose from civil dissensions, the account no doubt is correct which states that others settled in Acolhuacan, on the eastern shore of the principal lake in the Valley of Mexico. The name means " Colhuacan by the water," and was the State of which the capital was Tctzcoco. t This description is taken from the map of the location in M. Charnay's Andennes Villes du Nouveau Monde, p. 83. The measurements I have made from the map do not agree with those stated in the text of the book, but are, I take it, more accurate. t Sometimes called the Rio de Montezuma, and also the Tollanatt, water of Tula. This stream plays a conspicuous part in the Quetzalcoatl myths. It appears to be the same as the river ALoyac (= flowing or spreading water, all, loyaiia), or Xipacoyan (= where precious stones are washed, from ziuill, paca, yan), referred to by Sahagun, Hist, de la Nueva EKpana, Lib. ix, cap. 29. In it were the celebrated "Baths of Quetzalcoatl," called Atccpanamochco, "the water in the tin palace," probably from being adorned with this metal [Anales de Cuauhtitlan). g See the Codex Ramirez, p. 24. Why called Snake-Hill the legend says not. I need not recall how prominent an object is the .serpent in Aztec mythology. The name is a com- pound of c.oatl, snake, and tepetl, hill or mountain, but which may also mean towTi or city, as such were usually built on elevations. The form Coatepec is this word with the post- position c, and means "at the snake-hill," or, perhaps, " at Snake-town." II Or to one of them. The name is preserved by Ixtlilxochitl, Relaciones Hifloricas, in Kingsborough, Mexico, Vol. ix, p. 326. Its derivation is from paUi, a color (root pa), and the postposition pan. It is noteworthy that this legend states that Quetzalcoatl in his Brinton.] ^^^ [Sept. 2, represented by a few broken fragments, appears equal, but not superior, to that of the Valley of Mexico. Both the free and the attached column occur, and figure-carving was known, as a few weather-beaten relics testify. The houses contained many rooms, on different levels, and the roofs were flat. They were no doubt mostly communal structures. At the foot of the Serpent- Hill is a level plain, but little above the river, on which is the modern village with its corn-fields. These geographical particulars are necessary to understand the ancient legend, and with them in mind its real purport is evident.* That legend is as follows : When the Azteca or Mexica — for these names were applied to the same tribe \ — left their early home in Aztlan — which Ramirez locates in Lake Chalco in the Valley of Mexico, and Orozco y Berra in Lake Chapallan in Michoacan \ — they pursued their course for some generations in avatar as Cc Acatl was boru in the Palpan, " House of Colors ;' ' while the usual story was that he came from Tla-pallan, the place of colors. This indicates that the two accoxmts are versions of the same myth. * There are two ancient Codices extant, giving in picture-writing the migrations of the Mexi. They have been repeatedly published in part or in whole, with varying degrees of accuracy. Orozco y Berra gives their bibliography in his Hintoria Antigua de Mexico, Tom. iii, p. 61, note. These Codices differ widely, and seem contradictory, but Orozco y Berra has reconciled them by the happy suggestion that they refer to sequent and not synchronous events. There is, however, yet much to do before their full meaning is ascertained. '' t The name Aztlan is that of a place and Mexitl that of a person, and from these are derived Aztecatl, plural, Azteca, and Mcxicatl, pi. Mexica. The Azteca are said to have left Aztlan under the guidance of Mexitl {Codex Ramirez). The radicals of both words have now become somewhat obscured in the Nahuatl. My own opinion is that Father Duran {Hist, de Nueva Expana, Tom. i, p. 19) was right in translating Aztlan as "the place of whiteness," el lugar de blancura, from the radical tstac, white. This may refer to the East, as the place of the dawn ; but there is also a temptation to look upon Aztlan as a syncope of a-izta-tlah, = " by the salt water.' ' Mexicatl is a nomeii gentile derived from Mexitl, which was another name for the tribal god or early leader Huitzilopoehtli, as is positively stated by Torquemada {Mon- arquia Indiana, Lib. viii, cap. xi). Sahagun explains Mexitl as a compound of metl, the maguey, and citli, which means hare and grandmother {Historia de JShieva Espaiia, Lib. X, cap. 29). It is noteworthy that one of tlie names of Quetzalcoatl is Meconetzin. son of the maguey (Ixtlilxochitl, Rel. Hist., in Kingsborough, Vol. ix, p. 328). These two gods were originally brothers, though each had divers mythical ancestors. I Orozco y Berra, Historia Antigua de Mexico, Tom. iii, cap. 4. But Albert Gallatin was the first to place Aztlan no further west than Michoacan {Trans. American Kthnolog. Society, Vol. ii, p. 202). Orozco thinks Aztlan Avas the small island called Mexcalla in Lake Chapallan, apparently because he thinks this name means " houses of the Mexi ;" but it may also signify "where there is abundance of maguey leaves," this delicacy being called mncalli in Nahuatl, and the terminal a signifying location or abundance. (See Sahagun, Historia de Nueva Espaiia, Lib. vii, cap. 9.) At present, one of the smaller species of maguey is called mexcalli. 1887.] '^"*^ [Brinton. harmony ; but fit a certain time, somewhere between the eighth and tlie eleventh century of our era, they fell out and separated. The legend refers to this as a dispute between the followers of the tribal god Iluitzilopochtli and those of his sister Malinalxo- chitl. We may understand it to have been the separation of two " totems." The latter entered at once tlie Valley of Mexico, while the followers of Huitzilopochtli passed on to the plain of Tula and settled on the Coatepetl. Here, saj'^s the narrative, they constructed houses of stone and of rushes, built a temple for the worship of Huitzilopochtli, set up his image and those of the fifteen divinities (gentes?) who were subject to him, and erected a large altar of sculptured stone and a court for their ball play.* The level ground at the foot of the hill they partly flooded by damming the river, and used the remainder for plant- ing their crops. After an indeterminate time they abandoned Tula and the Coatepetl, driven out by civil strife and warlike neighbors, and journeyed southward into the Valley of Mexico, there to found the famous city of that name. This is the simple narrative of Tulan, stripped of its contra- dictions, metaphors and confusion, as handed down by those highest authorities, the Codex Ramirez, Tezozomoc and Father DuraiLJ" It is a plain statement that Tula and its Snake-Hill were merely one of the stations of the Azteca in their migrations — an impoi'tant station, indeed, with natural strength, and one that they fortified with care, where for some generations, prob- ably, they maintained an independent existence, and which the story-tellers of the tribe recalled with pride and exaggeration. How long they occupied the site is uncertain. | Ixtlilxochitl * It is quite likely that the very stone image figured by Charnay, Aiicievnrs Villes die Nouveau Monde, p. 72, ami the stone ring used in the tlachtli, liall play, wiiieh lie figures, p. 73, are those referroil to in the historic legend. t The Codex Bamiirz, p. 24, a most excellent authority, is quite clear.

This does not reflect creditably on the supposed singular cultivation of the Toltecs. Probably the warrior Aztecs sub- jected a number of neighboring tribes and imposed upon them rulers.* If we accept the date given by the Codex Ramirez for the departure of the Aztecs from the Coatepetl — A. D. 1168 — tlien it is quite possible that they might have occupied the site for a couple of centuries or longer, and that the number of successive chieftains named by Ixtlilxochitl should not be far wrong. The destructive battles of which he speaks as preceding their departure — battles resulting in the slaughter of more than five million souls — we may regard as the grossly- overstated account of some really desperate conflicts. That the warriors of the Azteca, on leaving Tula, scattered over Mexico, Yucatan and Central America, is directly contrary to the assertion of the high authorities I have quoted, and also to most of the mythical descriptions of the event, which declare they were all, or nearly all, massacred. f The above I claim to be the real history of Tula and its Serpent-Hill, of tlie Toltecs and their dynasty. Now comes the question, if we accept this view, liow did this ancient town and into a rational clirouology, remembering tliat there is an acknowledged hiatns of a number of years about the eleventh and twelfth centuries in the Aztec records (Orozco y Berra, notes to Codez Ramirez, p. 213). The Anales de Oiauhtitlan dates the founding of Tula after that of Tlaxcallan, Huexotzineo and Cuauhtitlan (p. 29). * As usual, Ixtlilxochitl coutradicts himself in his lists of rulers. Those given in his Hisforia Chichimeca are by no means the same as those enumerated in his Relaciones His- toricas (Kingsborough, Mexico, Vol. ix, contains all of Ixtlilxochitl's writings). Entirely different from both is the list in the Anales de Cuauhtitlnn. How completely euheme- ristic Ixtlilxochitl is in his interpretations of Mexican mythology is shown by his speaking of the two leading Nahuatl divinities Tezcatlipoca and Huitzilopochtli as "certain bold warriors" ("ciertos caballeros muy valerosos." Relaciones HistoHcas, in. Kingsborough, Vol. ix, p. 326). t See the note to page 3. But it is not at all likely that Tula was absolutely deserted. On the contrarj', Herrera asserts that after the foundation of Mexico and the adjacent cities (despues de la fundacion de Mexico i de toda la tierra) it reached its greatest celebrity for skilled workmen. Decadas de Indias, Dec. iii, Lib. ii, cap. 11. The general statement is that the sites on the Coatepetl and the adjacent meadows were unoccupied for a few years— the Anales de Ciuxuhtitlan says nine years— after the civil strife and massacre, and then were settled again. The Ilistoria de los Mexicanos por sus Pinluras, cap. 11, says, "y ansi fueron muertos todos los de Tula, que no qued6 ninguno." 1887.] ^dO [Brinton. its inhabitants come to have so wide a celebrity, not merely in the m^'ths of the Nahuas of Mexico, but in the sacred stories of Yucatan and Guatemala as well — which was unquestionably the case? To explain this, I must have recourse to some of those curious principles of language which have had such influence in building the fabric of mythology. In such inquiries we have more to do with words than with things, with names than with persons, with phrases than with facts. First about these names, Tula, Tollan, Toltec — what do they mean? The}' are evidently from tlie same root. What idea did it convey ? We are first struck with the fact that the Tula I have been describing was not the only one in the Nahuatl district of Mexico. There are other Tulas and Tollans, one near Ococingo, another, now San Pedro Tula, in the State of Mexico, one in Guerrero, San Antonio Tula in Potosi,* etc. The name must have been one of some common import. Herrera, who spells it jTuZo, by an error, is just as erroneous in his suggestion of a meaning. He says it means " place of the tuna," this being a term used for the prickly pear.f But tuna was not a Nahuatl word ; it belongs to the dialect of Haiti, and was introduced into Mexico b}^ the Spaniards. Therefore Herrera 's derivation must be ruled out. Ixtlilxocliitl pretends that the name Tollan was that of the first chieftain of the Toltecs, and that the}" were named after him ; J but elsewhere himself contradicts this asser- tion. Most writers follow the Codex Bamirez, and maintain that Tollan — of which Tula is but an abbreviation — is from tolin, the Nahuatl word for rush, the kind of which they made mats, and means "the place of rushes," or, where they grow. The respectable authority of Buschmann is in favor of this derivation ; but according to the analogy of the Nahuatl Lin- guage, the "place of rushes" should be ToUitlan or Tolinan^ and there are localities with these names.§ Without doubt, I think, we must accept the derivation of * See Buschmann, L'eber die Aztekischen Ortsnamen, ss. 682, 788.

Speaking of the early Aztecs, he says : " They arrived at the spot called Coatepec, on the borders of Tonalan, the place of the swn,"* This name, Tonallan, is still not unusual in Mexico. Busch- mann enumerates four villages so called, besides a mining town, Tonailan.-\ " Place of the sun " is a literal rendering, and it would be equall}^ accurate to translate it " sunny-spot " or " warm place " or " summer-place." There is nothing very peculiar or distinctive about these meanings. The warm, sunny plain at the foot of the Snake-Hill was called, naturally enough, Tonallan, syncopated to Tollan and thus to Tula, J But the literal meaning of Tollan — " Place of the Sun " — brought it in later days into intimate connection with many a myth of light and of solar divinities, until this ancient Aztec pueblo became apotheosized, its inhabitants transformed into magicians and demigods, and the corn-fields of Tula stand forth as fruitful plains of Paradise. In the historic fragments to which I have alluded there is scant reference to miraculous events, and the gods play no part in the sober chronicle. But in the mythical cyclus we are at once translated into the sphere of the supernal. The Snake- * Cronica Mexicana, cap. 1. " Particroii de alii y vinieron .4 la parte que llaman Coatepec, tL>rnilnos de Tonalan, lugar del sol." In Naliuatl tonallan usually means summer, sun-time. It is syncopated from tonalli and tlan; the latter is the locative termination ; tonalli means warmth, siinniness, akin to lonaiiiih, sun ; but it also means soul, spirit, especially when combined with the possessive pronouns, as to-tonal, our soul, our immaterial essence. By a further syncope tonallan was reduced to Tollan or Tullan, and by the elision of the terminal semi-vowel, this again became Tula. This name may therefoi'e mean "the place of souls," an accessory signification which doubtless had its iniiuence on the growth of the myths concerning the locality. It may be of some importance to note that Tula or Tollan was not at first the name of the town, l>ut of the locality— that is, of the warm and fertile meadow-lands at tlie foot of the Coatepctl. The town was at first called Xoeotitlan, the place of fruit, from xocotl, fruit, ti, connective, and tlan, locative ending. (See Sahagun, Ilistoria de Niicva Espana, Lib. X, cap. 20, sees. 1 and 12.) This name was also applied to one of the quarters of the city of Mexico when conquered by Cortes, as we learn from the same authority. t Buschmann, Ueber die AzteHschen Ortsnamen, ss. 794, 797 (Berlin, 1852). t The verbal radical is tona, to warm (hazer calor, Molina, Vocabidario de la Lcngua Mexicana, s. v.); from this root come many words signifying warmth, fertility, abun- dance, the sun, the east, the summer, the day, and others expressing the soul, the vital principle, etc. (Simt'on, Diet, de la Langue Nafumtl, s. v. tonalli.) As in the Algonkin dialects the words for cold, night and death are from the same root, so in Nahuatl are those for warmth, day and life. (Comp. Duponceau, Mcmoire sur Ics Langucs de I'Amcr- ique du Nord, p. 327, Paris, 183G.) 1887.] ■^»^* [Brinton. Hill Coatepetl becomes the Aztec Ol^-mpus.

One da}- while thus engaged, a little bunch of feathers fell upon her, and she hid it under her robe. It Avas the descent of the spirit, the divine Annunciation. When the Myriad Sages saw that their mother was pregnant, they were enraged, and set about to kill her. But the unborn babe spake from her womb, and provided for her safety, until in due time he came forth armed with a blue javelin, his flesh painted blue, and with a blue shield. His left leg was thin and covered with the plumage of the humming-bird. Hence the name was given to him " On the left, a Humming-Bird," Huitzi- lopochtli.| Four times around the Serpent-Mountain did he drive the Myriad Sages, until nearl}- all had fallen dead before his dart, and the remainder fled far to the south. Then all the Mexica chose Huitzilopochtli for their god, and paid honors to the Serpent-Hill by Tula as his birthplace. § * Coatlan, to-nan, from coatl, serpent ; tla7i, among ; to-nan, our mother. She was the goddess of flowers, and the florists paid her especial devotion (Sahagun, Historia, Lib. ii, cap. 22). A precinct of the city of Mexico was named after her, and also one of the edifices in the great temple of the city. Here captives were sacrificed to her and to the Iluitznahua. (Ibid., Lib. ii, Appendi.x:. See also Torquemada, Mvnarquia Indiana, Lib. X, cap. 12.) t Ccntzon Huilznahua, "the Four Hundred Diviners with Thorns." Four hundred, how- ever, in Naliuatl means any indeterminate large niunber, and hence is properly trans- lated myriad, legion. Kahuatl means wise, sliillful, a diviner, but is also the proper name of the Naliuatl-speakiug tribes ; and as the Nahuas derived their word for soutli from hui-Jli, a thorn, the Iluitznahua may mean "the southern Naliuas." Suhagun had this in his mind when he said the Iluitznaliua were goddesses who dwelt in tlie south (iZt.s- toria dc Nutva E'-pana, Lib. vii, cap. 5). The word is talcen by Father Duran jis tlie proper name of an individual, as we sliall see in a later note. X HuitzilopocfUU, from huii-ilhi, hiunmiug-bird, opuchtU, the left side or hand. Tliis is the usual derivation ; but I am quite sure that it is an error arising from the ikonomatic representation of the name. The name of liis Ijrother, Huitznahua, indicates strongly that the preflx of both names is identical. This, I doubt not, is from huitz-tlan, the south ; ilo is from iloa, to turn ; tliis gives us the meaning " the left liand turned toward the south." Orozco y Berra has pointed out that the Mexica regarded left-handed warriors as tlic more formidaljle {Historia Anlir;ua de Mexico, Tom. i, p. 125). Along with this let it be remembered that the legend states tliat Huitzilopochtli was bom in Tula and insisted on leading tlio Mexica toward the south, the oppositi(jn to which by his brotlier led to the msissacre and to the destruction of the town. g This myth is recorded by Saliagun, Historia de Nticva Expana, Lib. iii, cap. 1, "on the Origin of tlie Gods."

The brothers were the black and the white Tezcatlipoca and the fair-skinned, bearded Quetzalcoatl. Yet a third myth places the birthplace of Qaetz- alcoatl directly in Tula, and names his mother, Chimalman, a virgin, divinely impregnated, like Coatlicue, by the descending spirit of the Father of AIL* Tula was not only the birthplace, but the scene of the highest activity of all these greatest divinities of the ancient Nahuas. Around the Coatepetl and on the shores of the Tollanatl — " the Water of Tula " — as the stream is called which laves the base of the hill, the mighty struggles of the gods took place which form the themes of almost all Aztec m3thology. Tulan itself is no longer the hamlet of rush houses at the foot of the Coatepec, surmoimted by its pueblo of rough stone and baked brick. It is a glorious city, founded and governed by Quetzalcoatl himself, in his first avatar as Hueman, the strong-handed. "All its structures were stately and gracious, abounding in ornaments. The walls within were incrusted with precious stones or finished in beautiful stucco, presenting the appearance of a rich mosaic. Most wonderful of all was the temple of Quetzalcoatl. It had four chambers, one toward the east finished in pure gold, another toward the west lined with torquoise and emeralds, a third toward the south decorated with all manner of delicate sea- shells, and a fourth to the north resplendent with red jasper and four-hundred men and five women for him to eat. At the death of the women their robes were preserved, and when the people carried these to the Coatepec, the five women came again into being. One of these was Coatlicue, an imtouched virgin, who after tour years of fasting placed a bunch of wliite feathers in her bosom, and fortliwith became pregnant. She brought forth Huitzilopochtli completely armed, who at once destroyed the Huitznahua. Father Duran translates all of this into plain history. His account is that when the Aztecs had occupied ToUan for some time, and had fortified the hill and cultivated the plain, a dissension arose.

What the siege of Troy- was to the Grecian poets, the fall of Tula was to the singers and story-tellers of Auahuac — an inexhaustible field for imagination, for glorification, for lamentation. It was placed in the remote past — according to Sahagun, perhaps the best authority, about the year 319 before Christ.* All arts and sciences, all knowledge and culture, were ascribed to this wonderful mythical people, and wherever the natives were asked concerning the origin of ancient and unknown structures, the^^ would reply," The Toltecs built them."t They fixedly believed that some day the immortal Quetzal- coatl would appear in another avatar, and would bring again to the fields of Mexico the exuberant fertility of Tula, the peace and happiness of his former reign, and that the departed glories of the past should surround anew the homes of his votaries.^ I have elsewhere so fully represented this phase of the mj^th- ical C3'clus that I need not emphasize it further ; nor need I explain the significance of these myths as revealed to us by an application of the principles of comparative mythology ; for that, too, would be repeating what I have already published in ample detail. What I wish to point out in clear terms is the contrast between the dry and scant}^ historic narrative Avhich shows Tula with its Snake-Hill to have been an earlj' station of the Azteca, occupied in the eleventh and twelfth centur^^ by one of their clans, and the monstrous m3'th of the later priests and poets, which makes of it a birthplace and abode of the gods, and its inhabitants the semi-divine conquerors and civilizers of Mexico and Central America. For this latter fable there is not a vestige of solid foundation. The references to Tula and * Historia de Nueva Espana, Lib. viii, cap. 5. t Father Duraii relates, " Even to this day, when I ask the Indians, ' Wlio created this jiass in the mountains?

J Quetzalcoatl announced that his return should take place 5012 years after his final departure, as is mentioned by Ixtlilxocliitl (in Kingsborough, Mexico, Vol. ix, p. 33:!). This number has probably some mystic relation to the calendar. 1887.] ^41 [Brinton. the Toltecs in the Chronicles of the Maxjas and the Annals of the Kakchiquels are loans from the later mythology of the Nahuas. It is high time for this talk about the Toltecs as a mighty people, precursors of the Azteca, and their instructors in the arts of civilization, to disappear from the pages of his- tory. The residents of ancient Tula, the Tolteca, were nothing more than a sept of the Nahuas themselves, the ancestors of those Mexica who built Tenochtitlan in 1325. This is stated as plainl}' as can be in the Aztec records, and should now be con- ceded by all. The mythical Tula, and all its rulers and inhab- itants, are the baseless dreams of poetic fancy, which we prin- cipally owe to the Tezcucan poets. In conclusion, I have no hesitation in repeatii^g the words which I printed some 3'ears ago, and which gave considerable offence in certain quarters : " Is it not time that we dismiss, once for all, these American myths from the domain of historical traditions? Wh}' should we try to make an enlightened ruler of Quetzalcoatl, a cultured nation of the Toltecs, when the proof is of the strongest that the}' are the fictions of m3-thol- ogy ? Let it be understood hereafter that whoever uses these names in an historic sense betrays an ignorance of the subject he handles, which, were it in the better-known field of Aryan or Egyptian lore, would convict him of not meriting the name of scholar." * * Antcrican Hero Myths, p. 35. The only writer ou ancient American history before me who has wliolly rejected the Toltecs is, I believe, Albert Gallatin. In his able and critical study of the origin of American civilization {Transactions of the American Ethno- logical Society, Vol. i, p. 203) he dismissed them entirely from historical consideration with the words : " The tradition respecting the Toltecs iiscends to so remote a date, and is so obscure and intermixed witli mythological fobles, that it is impossible to designate either the locality of their primitive abodes, the time when they first appeared in the vicinity of the Valley of Mexico, or whether they were preceded by nations speaking the same or different languages." Had this well-grounded skepticism gained the ears of writers since 1845. when it was published, we should have been saved a vast amount of rubbish which has been heaped up under the name of history. Dr. Otto StoU {Guatemala; Reit'cn und Schilclerungen, ss. -108, 409, Leipzig, I8861 has joined in rejecting the ethnic existence of the Toltecs. As in later Xahuatl the word toltecatl meant not only "resident of Tollan," but also "artificer" and "trader," Dr. Stoll thinks that the Central American legends which speak of " Toltecs" should be in- terpreted merely as referring to i'oreign mechanics or pedlars, and not to any particular nationality. I quite agree with tliis view. PUOC. AMER. I'HIIiOS. SOC. XXIV. 136. 2e. PRINTED OCT. 22, 1887. Kirkwood.] - ^4:Z [Se-pt. 2, Biela's Comet and the Large Meteors of November 27-30. By Professor Daniel Kirkwood. {Bead before the American Philosophical Society, September 2, 1881.') The well-known catalogue of Greg, published in the Report of the British Association for 1860, p. 115 et seg., designates the last days of November as one of the dates at which an unusual number of fire-balls and meteoric stones had fallen since the commencement of the nineteenth century. In the Danville Quarterly Review for December, 1861, the gradual dissolution of Biela's comet was suggested as the source of those periodic displays,* and the same theory was again advanced in the author's "Meteoric Astronomy" (1867), pp. 54, 121, and 126-129. The suggestion has also been made independently by others. We give below the most distinguished star showers derived from the scattered portions of Biela's comet : — 1798. 7 December ; recognized as Andromedes by Newton. 1830. 7 December ; Quetelet's catalogue. 1838. 5 to 7 December ; recognized by Newton. 1850. 29 November ; Quetelet. 1872. 27 November. 1885. 27 November. From 1798 to 1885, we have eighty-seven years = 6.692 x 13 ; and the series is harmonized in the following scheme : — 1798 to 1838 = 40 years = 6 x 6.66 + 1830 to 1850 = 20 " = 3 X 6.66 + 1838 to 1872 = 34 " = 5 X 6.80. 1872 to 1885 = 13 " = 2 X 6.50. The dates, it will be observed, indicate considerable extension of the cluster, or rather, perhaps, the existence of several groups. The remarkable fall of meteoric iron during the shower of Bielids on the 27th of November, 1885,f at once suggests the inquiry whether traces of the same period can be found in the recurrence of fire-balls and aerolites at the identical epoch. The following dates, except the last, are all derived from the catalogue of Mr. R. P. Greg : — 1809. 29 November ; a fireball at Munich. 1810, 28 November, 9.30 p. m. ; an aerolitic meteor at Cape Matapan. *" The division of Biela's comet into two distinct parts suggests several interesting questions in cometary physics. * * * May not the force, whatever it is, that has pro- duced o>ie separation, again divide the parts ? and may not this action continue until the fragments become invisible?

The first noticeable sign of approaching reproductive fission consists in an increased extrusion of the body substance, speedily followed by the formation of fine cilia on the anterior surface, with the appearance of a transverse constriction subceutrally situated on the extruded portion, as in Fig. 23. This constriction deepens, the cilia increase in length, soon entirely clothing the frontal region and one lateral margin, and, by the time the division is completed, the posterior border as well. At the final separation of the embryo it is ovate, coarsely granular, with a somewhat conspicuous nucleus. It speedily becomes elongated and flattened, as in Fig. 24, its length exceeding the height of the mature animalcule. The cilia are confined to the extremities and the lower surface, while a few short, capitate tentacles are scattered over the superior aspect. After the departure of the embryo the remaining portion of the mature animalcule withdraws itself into the lorica, as in Fig. 22, the anterior, subspherical region remaining exposed and the tentacles protruded. The latter become fevver in number, but are not entirely withdrawn during the reproductive act. After it they become more numerous. The presence of the short, button-like pedicle of some individuals gives the lorica an appearance closely resembling that of Solenophrya, to which genus they might readily be relegated if not seen scattered among the more abundant and more distinctly pedicellate forms.

Preliminary Report on the Vertebrate Fossils of the Uinta Formation, collected by the Princeton Expedition of 1886. By W. B. Scott and Henry F. Osborn. {Bead before the American Philosophical Society, Sept. 2, 1887.) The Uinta formation, which was first identified by Prof. Marsh, is one of great interest, as it is just intermediate between the Bridger and the White River groups. It has as yet been comparatively little explored, and much r&mains to be done, but enough is now known to render possible some account of this most important intermediate fauna. Crocodilus, sp. indet. Trionyx, sp. indet. Hyopsodus gracilis Marsh. Mesonyx uintensis Scott. REPTILIA. MAMMALIA. Lemukoidea. Creodonta. Carnivora. Amphicyon (?) vulpinum, sp. nov. — The probable existence of this genus in the Uinta beds is indicated bj-- a lower premolar and lower sec- torial molar. The premolar, probably the third, consists of a high, acute and compressed cone, with rudimentary posterior heel ; a cingulum runs entirely around the crown, and is most conspicuous on the anterior sur- face. This tooth differs from the premolars of most of the European species of Ampldcyon in the fact that the main cusp has no accessory tubercles developed upon it. The sectorial molar is canine in character ; the blade consists of three cusps, of which the external is the larger, and the anterior is very low ; the sectorial blade is therefore much less devel- oped than in Cynodietis, and hardly more than in Miacis ; the heel is low and small and not very distinctly basin-shaped. These teeth are insuffi- Scott and Osborn.] -^^ [Sept. 2, cient for a final reference of the specimen, wliicli may possibly belong to Miaeis, but for stratigrapbical reasons I think it more probably a species of Amphicyon.

These may belong to the very large species of Mesonyx from the same beds, or to something quite different. No deter- mination can be made at present. RODENTIA. Plesiaretomys sciuroicles, sp. nov. — Rodents have not as yet been an- nounced from the Uinta deposits ; representatives of two genera were, however, obtained by the Princeton party, one of which is the Plesiare- tomys of the Wasatch and Bridger. In this species the molar formula is J ; it differs from the other species of the genus which Cope defines as having the transverse crests of the upper molars "obsolete or wanting," in the structure of the upper molars, which are entirely like those of Sciurus, and consist of two external cusps, from which run two trans- verse crests, meeting internallj' and forming a V. The first upper premo- lar is very small and single-rooted. The lower molars are very like those of the Bridger species ; there are four marginal tubercles surrounding a median depression ; the antero-internal cusp is the highest ; a low trans- verse crest connects the anterior pair of tubercles and a less distinct crest the posterior pair. These crests are better marked than in most species of Plesiaretomys. The skull has no post-orbital processes and a very large infra-orbital opening ; the cranium is broad and flat, without sagittal crest, the inion low and rounded, the zygomatic arches much depressed and very thin , the cerebral hemispheres are entirely unconvoluted and leave the olfactory lobes and cerebellum exposed completely. This species is very small, less in size than Plesiaretomys delicatissimus. Measurements. M.

A second species of rodent is represented by a lower incisor and part of the mandible, but as no molars are preserved, the specimen cannot be referred to any genus. The Incisor is very much larger than in any known species of Plesiarctomys, and equals that of the beaver in size. It may not improbably belong to some ancestral member of the Castoridm, as that family is known to exist in the overlying White River beds. Measurements. M.

(JAgrioclioeruslsl&r&Xx). — This genus is of interest as being the direct forerunner of the Oreodontida, which are so characteristic of the American Miocene formations. It differs from Oreodon in the structure of the upper molars, which have five cusps, an intermediate one appearing between the anterior pair. The crowns of the upper molars are very wide and the internal crescents separated from the external by a considerable interval, much as in Agriochoerus. Both upper and lower premolars are somewhat simpler than in Oreodon, and the latter are trenchant, as in Tragidus. It differs very radically from Agriochoerxis in the character of the premolars as well as in the presence of the inter- mediate cusp in the superior molars. The orbit is not enclosed behind, the cranium is narrower and less rounded and the brain smaller than in Oreodon. On the other hand, its relationship with that genus is incon- testable ; the lower teeth form a closed series without any diastemata, the lower canine has gone over to the incisor series, and the first premolar has taken on the form and function of the canine, a peculiarity found only among the Oreodontidai. As in that family, the mandible is short, deep, and has an abruptly rounded chin. The number of digits is uncertain, but is probably v-iv, as is unques- tionably the case in Oreodon ; the magnum has not moved so far to the radical side, but is more directly under the magnum than in the latter genus. In the tarsus the external and median cuneiforms are fused together as in Oreodon, but the line of union is much more plainly marked than in that genus. Protoreodon parvus : Upper molar series, natural size. Tlie inner cusp of the third premolar has been broken away. This species was of very small size, much inferior to Oreodon gracilis. PKOC.

Leptotragulus proavus, gen. et sp. nov.^ — This genus resembles the White River form Leptomeryx, but differs from it in the somewhat less complex structure of the last lower premolar, and in the presence of a strong accessory column between the external cusps of the lower molars. In all probability also this genus had separate metapodials, while in Leptomeryx there is a cannon bone in the hind foot. Apparently the nearest ally of this genus is the Pi'odremotJierium of Filhol, with which indeed it may prove to be identical ; at present, however, we have judged it best to sep- arate the American species, as aside from the fact that Prodremotheririm has cannon-bones ia both fore and hind feet, the last lower premolar, judging from Filhol's figures,! is somewhat more complex in structure, and less distinctly trenchant than in Leptotragulus. The latter is at once distinguished from its cotemporary Protoreodon, by the form of the mandi- ble, which is very slender, with tapering chin and diastema behind the canine, while in Protoreodon the mandible is deep with abruptly rounded chin and no diastema ; a further difference is found in the premolar for- mula of the lower jaw, four in Protoreodon, three in Leptotragulus. The premolars resemble most those of the tragulines ; the last one consists of a high, sharp and compressed cone, with a very small autero-internal cusp, and a narrow valley on the posterior edge enclosed between two thin plates of enamel ; this valley is not complicated by the accessory tubercles found in Leptomeryx. The species L. proamis considerably exceeds in size the Leptomeryx Evansi of the White River formation, and is somewhat larger than Tragulus javanicus. The crowns of the lower molars are low and broad in proportion to their length. * Am. Jour.

The systematic position of this genus can liardly be decided from tlie material now at command ; it may be a forerunner of Leptomeryx, the only genus of the White River formation which at all resembles it ; it may be an ancestral type of the Cervidce, or a member of the traguline series. These questions must for the present be left open. Measurements. M.

As, however, no definition of these names has as yet been offered, they cannot be used. Perissodactyla. Epihippus uiniensis Marsh. f — This genus differs from the Bridger Pliolophiis in having the last two inferior premolars of the molar pattern. Epihippus grncilis Marsh. — Some beautifully preserved specimens of this small species are in the collection and show interesting differences from the Wasatch Ilyracotherimn. The characteristic equine cusps at the inner angle of the Vs on the lower molars are more isolated and distinct ; the limb bones are proportionately longer and more slender ; the carpus is higher and narrower ; the magnum is more depressed and like that of AncliUlie,rium in shape ; there are still four digits in the manus, but No. V is very slender ; the ulna is still further reduced. Epihippus forms a very interesting transition to the horses of the overlying White River deposits. Hyrachyas obliquideiu, sp. nov.— Specimens of this genus are not at all uncommon in the Uinta deposits, but the only ones which can as yet be satisfactorily determined belong to a species different from any of the known Eridgcr species. This species is characterized by the last upper molar, which has become exceedingly oblique and very like the corre- sponding tooth of Aceratherium ; the antero-extcrnal lobe is greatly reduced in size, the external wall of the crown is nearly parallel to the posterior transverse crest and prolonged but little beyond it, so that the posterior valley is almost obsolete, being even less developed than in * Introd. and Succ. of Vert. Life in America, pp. 20, 30. t Loc. cit., p. 24. Scott and Osborn.] ^^^ [Sept. 2, Hyracodon. The rest of the dentition shows no particular deviation from the usual type, nor are important differences from the Bridger species observable in the skeleton, except perhaps a slight reduction in the rela- tive size of the lateral digits. In size this species about equals H. agra- rius. Prothyracodon intermedium, gen. et sp. nov. — This very interesting type is apparently intermediate between Hyrachyus and Hyracodon. The type specimen consists of a fragment of the superior maxillary contain- ing the fourth premolar and second molar in place, with the alveolus of the first molar. As in Hyrachyus the premolar has but a single internal cusp and two transverse crests enclosing a valley. The external cusps are like those of Hyracodon, the outer wall of the crown being nearly flat and suhquadrate in outline ; the two constituent cusps are but faintly indicated, but are somewhat more pronounced than in Hyracodon. An antero-ex- ternal buttress or fold of the cingulum is present, as in both the Bridger and White River genera. The second molar is essentially the same as in Hyracodon ; the antero- external lobe is much more reduced than in Hyrachyus, and the transverse crests directed more obliquely inwards and backwards ; but on the other hand, the projection from the anterior crest into the median valley which is to be seen on all the molars of Hyracodon is here wanting. The present species is quite small ; it is about the size of Hyracliyus agrarius. Measurements. M. Fourth upper premolar, anteroposterior diameter 010 " " " transverse " 014 Second upper molar, antero-posterior diameter 016 " " " transverse " 0175 Isectolophus annectens, gen et sp. nov. — This genus is closely allied to Helaletes of the Bridger, but its dentition is one step nearer to that of the tapir. In Helaletes the antero- external cusp of the upper molars is less reduced and there is less difference between that and the postero- external cusp, than in Hyrachyus. This tooth structure would almost suffice to remove Helaletes from the Lophiodontido} as defined by Cope. In Isectolo- phus this equality of the external cusps is still better marked, and, more important still, the external wall is extended behind the posterior pillar just as in the tapir, so that this pillar becomes a median thickening of the posteroexternal cusp, instead of being a thickening of the posterior edge of that cusp, as in Hyrachyus and Helaletes. The first and second upper molars are thus almost exactly like those of the tapir ; the transverse crests are low and thick, and a strong cingulum surrounds the crown. The premolars are probably all simpler than the molars ; at all events this is true of the third. The lower molars are like those of Helaletes, and the last one has a well-developed heel or third crest ; there seems, how- 1887 ] ^Oi [Scott and Osborn. ever, to have been a diastema between the canine and first premolar, though this is not certain, which is not the case in Uelaletes.

Much more probably this line has come down through the genera with trilobed last lower molar, and it is noteworthy that the tapiroids from the White River beds have the third lobe or talon present, though less distinctly marked. These animals have been described by Dr. Leidy,* under the name of Lophiodon, from which genus the known specimens do not appreciably differ. But, as Dr. Leidy lias suggested, they probably belong to a very different genus, which, when better known, will in all likelihood be found to be intermediate in character between Isectolophus of the Uinta and Tapiravus of the Loup Fork. According to this view the series of genera would be : Helaletes, Isectolophus, the White River genus, Tapiravus and Tapirus. Amynodon ]\Iarsh {Syn. ? Orthocynodon, nobis). — Professor Marsh's description of this genus is as follows :f "The skull is intermediate in form between tllat of a Tapir and a Rhinoceros, but the molar teeth are entirely of the latter type. The premolars are all unlike the molars, and the canines above and below are very large. The incisors are small and the inner one in each jaw is lost in the present adult animal. The lower canines are placed nearly horizontal, and, taken in connection with the rest of the anterior dentition, they prove conclusively that the large lower teeth usually regarded as incisors in Aceratherium * * * are really canines." The number of digits is stated to be iv-iii. This description is erroneous in most of the particulars, owing to the fact that it was drawn up before the type specimen had been removed from the matrix and put together, and in this way, even after examining the type ourselves, as * Ext. Mamm. Faun, of Dak. and Neb., p. 239. t Am. Journ. Sei. and Arts, Third Ser., Vol. xiv, p. 251. Scott and Osborn.] ^^^ [Sept. 2, Professor Marsh kindly allowed lis to do, we were formerly led to con- sider the Bridger species as a distinct genus- {Orthocynodon). The numerous specimens from the Uinta formation now in the Prince- ton collection show that Ortliocynodon is very probably identical with Amynodon. The premolars are not all unlike the molars, as the third and fourth of the upper premolar series have all the molar elements, but are somewhat smaller ; the incisors are present in their full number in the upper jaw; the lower canines are not procumbent but fully erect. We can therefore confirm Professor Marsh's statements only with regard to the pattern of the molar teeth and probably also as to the number of digits. Amynodon advenus Marsh is the only species as yet known from the Uinta beds, in which, especially in the higher strata, it is very abundant. Diplacodon elatus Marsh. f — This animal, the largest yet known from the Uinta, is of especial interest as being intermediate between the Cha- litherioids of the Bridger (Palceosyops, Leurocephalus, etc.), and the gigan- tic MenodontldcB of the White River, as was first suggested by Professor Marsh. The dentition is like that of Palceosyops, but the premolars have commenced to assume the molar pattern ; there are, however, no traces of the horn-like processes so characteristic of Menodus. The skeleton, which is very fully represented in the collection, is massive, and in many respects closely like that of Menodus. The cervical vertebrse are short, with opisthoca3lous centra and quite long spines ; the dorsal vertebrse are heavy and in the anterior region have very long spines, which, however, do not reach the extreme length found in Menodus; the lumbars are rhinocerotic in character ; the ribs are long, flattened and heavy. The scapula is, like that of Menodus, very rhinocerotic, long and narrow, but with more abruptly rising spine and rudimentary metacromion ; the humerus is very massive, with strongly developed deltoid hook and supin- fitor ridge ; this humerus is a somewhat reduced copy of that of Menodus; the ulna is stout for its entire length and has a very prominent olecranon ; the radius diflfers in no essential except size from that of Menodus ; the carpus is low and broad, the metacarpals and phalanges like those of Palceosyops, only stouter. The pelvis is like that oi Palceosyops, with long, pedunculate and plate-like ilium, which is not everted nearly so much as in Menodus, and long, heavy and trihedral ischium ; Ihe femur is long and massive, with very prominent third trochanter, and with the rotular trochlea narrower and deeper than in Mtnodus ; the tibia is shorter than the femur ; the calcaneum has a very long tuber calcis and a narrow cuboidal facet, considerably narrower than in Palceosyops ; it appears also to possess the distinct fibular facet which is found in Menodus ; the astrag- alus is broader and shallower than in Palceosyops, and has a more exten- * Bull.

Tlie number of digits is apparently iv-iii. The characters revealed by this skeleton abundantly confirm Professor Marsh's view that Diplacodoti is to be regarded as the ancestor of 3/e«odws, and as a descendant of the Bridger Chalicotherioids. The Uinta fauna differs in many very important respects from that of the Bridger formation, both in what it possesses and in what it lacks ; nev- ertheless it is on the whole more closely akin to the Bridger than to the White River fauna. The great Dinocerata seem to have completely dis- appeared, as have also the Tillodonta ; rodents, lemiiroids, and creodonts are very much less common than in the Bridger, and what seem to be the first true American carnivores have appeared ; perissodactyls of chali- cotherioid, lophiodont, equine and rhinocerotic types are still very numer- ous. But the most remarkable and striking change consists in the extra- ordinary increase in the number of selenodont artiodactyls, which are exceedingly rare in tlie Bridger, but in the Uinta are perhaps more abun- dantly represented, as far as individuals are concerned, than any other group of mammals ; in character these artiodactyls are distinctly like those of the White River epoch. As yet no bunodont artiodactyls haA'^e been discovered, though they doubtless existed. With the possible excep- tion of Agriochoerus (see p. 257), no genus is yet known which is com- mon to the White River and Uinta formations, while several Bridger genera are represented in the latter ; there are Plesiarctomys, Mesonyx, Ilyrachyus, Amynodon, and perhaps others. No perissodactyl in which the premolars have all taken on the molar pattern, and no artiodactyl with coalesced metapodials, is known in this fauna, which thus has a dis- tinctly older facies than the fauna of Quercy,* which, hop,'ever, agrees witli it in the great increase in selenodonts. Schlosserf considers the Uinta fauna as Oligocene, but, as we believe, without good reason, since not a single Miocene genus has been found in it, the genera being all either com- mon to the Bridger or peculiar to the Uinta. The term oligocene is much more properly applied to the overlying White River beds, as has been done by Messrs. Cope and Filliol.:]; It seems, therefore, best on the whole to regard the Uinta as forming the summit of the eocene, as Professor Marsh, who first described its fauna, has done.

The true position of the bird-lice has been in debate for many years, and it is only recently that, in the excellent essay of Grosse,* we have such an exact account of the mouth- parts of these insects, as to enable us to perceive that they have been wrongly referred to the Hemiptera. With the new information aftbrded by Grosse, who does not himself add any general conclusions as to tlie systematic position of the Mallophaga, be- yond stating that they are not Hemiptera, nor allied to the true lice, we have for our own satisfaction made some comparisons with the Psocidaj, to which, among winged insects, the parasites in question seem nearest allied. The name Mallophaga was first proposed by Nitzsch in Germar's "Mag. derEntomologie," iil, 270, 1812. f In Gerstaecker's "Arthropoden" of Peters and Carus' " Handbuch der Zoologie" (1863), where this group is placed with the lice among the Hemiptera, it is stated that Burmeister regarded the Mallophaga as Orthoptera : "Zwiscben welchen und den Hemipteren sie in Anbetracht ihrer Verwandtschaft mit den Lausen ein Uebergangsglied abgeben, ohne fiiglich einer von beiden Ordnungen direct zugewiesen werden zu konnen." In our "Guide to the Study of Insects " (1868), and in subsequent editions, influenced by general usage and also by Melnilcow's arguments, based on embryological studies, we placed the Mallophaga among the Hemiptera, next to the true lice. In most, if not all German, Dutch, and French, as well as English text-books, the Mallophaga, if referred to, are described with the true lice. But, in his article, "Insects," in the "Encyclo- * Beitrage zur Kenntniss der Mallopliagen. Von Dr. Franz Grosse. Zeits. fiir wissen. Zool., xlii, 1885, pp. 530-558. A lengthy illustrated abstract by Prof. G. McCloskey will be found in the American Naturalist, April, 1886, pp. .340-318. 1 1 am indebted to Dr. Hagen for this reference to Kitzsch's paper. 265 [Packard. psedia Biitannica, " Otliedit., Mr. R. McLachlan claimed that these insects should be regarded as degraded Pseudoneuroptera. This view seems a natural one. Struck by this suggestion, and before reading Nitzsch's essay on the internal anatomy of Atropos, we had been led into compari- sons with the Psocida?, particularly the wingless form Atropos, to which, as we hope to show, with the aid of Grosse's results, the bird-lice are more closely allied than to any other group of insects. Grosse himself, unfortunately does not intimate what his views are as to the exact sys- tematic position of the group under consideration, beyond affirming that they certainly are not Hemiptera. We will now turn to the conclusions of jNIelnikow,* derived from a study of the embryology both of the Mallophaga and the true lice. In this essay the author thus sums up his views as to the affinities of the Mallo- phaga : "The study of the embryology of the Pediculida? and Mallophaga affords proof of a complete similarity in the mode of development of these two groups of animals. We are convinced that the similarity urged is seen not only in the identity of the formation of the primitive streak and the relations of the embryonal membranes, but also in other more subor- dinate features of the development. We have for example perceived that in the lice as well as the Mallophaga a provisional mass of cells is formed before the completion of the blastoderm ; that both have the provisional membrane which the larva leaves behind it in the egg at the time of hatching. Finally we are in a position to state that the beaks of both groups of insects are independently formed of the appendages of the head- segments. "These, though subordinate processes of development, appear to us to be of more value in the comparison of the insects under consideration than the relations of the mode of formation of the primitive streak and of the embryonal membranes, since the last without doubt is generally common to those insects with an internal primitive streak, but the former must be regarded as the distinctive feature of the insects under consideration. "If we add to the results mentioned, the fact that the anatomical struc- ture of the mouth-parts in the insects of the two groups agrees in all essential points ; if we add the generally similar external form of these insects, finally their ectoparasitic mode of life, then we need not hesitate to recognize the close relationship of the lice and Mallophaga. "This conviction is not insignificant, since it aftbrds us the possibility of decisively answering the question as to the systematic position of these insects. "After the researches of Burmeister it was generally considered that the Pediculidaj belonged to the Hemiptera. The structure of their mouth- parts and the incomplete metamorphosis they undergo are the reasons which confirm such a view. * Beitriige zur embryonal Entwickelung der Insektcn. Archiv f.

Packard.] ZOO [Sept. 2, "But the Mallopliaga were regarded by De Gear as a special group, and by Nitzscli and others they were generally referred to the Orthoptera. So far as I am aware, only Gerstaecker, in his "Handbuch der Zoologie," places the Mallophaga at the end of the Hemiptera ; still he is inclined to consider the group as a special one, forming a sort of transition from the Hemiptera to the Orthoptera, but without forming a direct connecting link. " Since until now, we knew only of the biting mouth-parts of the Mallo- phaga, so the view that they were entitled to be regarded as Orthoptera •was completely founded. In the Orthoptera we place those insects with an incomplete metamorphosis and biting mouth-parts. But after the exist- ence of a beak in the Mallophaga has been proved, it becomes evident that they should be regarded as Hemiptera or bugs. "This conclusion is wholly indisputable when we recall the above men- tioned similarity of the Mallophaga with the genuine lice. As to the completeness of this similarity, I will call attention again to the relations of the mouth parts, which have been cleared up by our embryological studies. We are thereby brought to the conviction that in the lice as well as in the Mallophaga, in their adult condition, no underlip (labium) exists, while the mandibles and maxilla3 are present. The only difference in the mouth-parts of the two groups is this : that in the Mallophaga these head- appendages are the functional parts of the mouth-apparatus, while in the Pediculidse they become rudimentary. "But such relative difierences do not have so great systematic value as to lead us to place so nearly related animals in two different orders. "From the reasons we have presented we adopt the Linnean view that the'Mallophaga belong with the Pediculidaj ; we think we are right in re- garding both groups as families of the Rhynchota." From the foregoing facts and conclusions of Melnikow, we felt con- vinced that he had demonstrated that the Mallophaga were Hemiptera and nearly related to the Pediculidae. But after a, careful reading of Grosse's memoir on the Mallophaga, translated by Prof. McCloskey, we think he is right in considering that these biting lice are not genuine Hemiptera. The very fact, admitted by Melnikow, that the mandibles and maxilife re- tain their biting function and do not become rudimentary as in the Pedi- culidse, and the fact pointed out by Grosse, that the second maxilhe do exist in the Mallophaga, leads us to regard their louse-like shape as simply adaptive, and that they belong to souie other group than the Hemiptera. If we examine Melnikow's excellent figures we see that after the mouth- parts of the embryo of both the genuine Pediculidie and Mallophaga are developed, the embryos of the two groups follow different developmental paths. The large clypeal region of the Mallophaga becomes still larger and broader, overhanging and concealing from above the labrum, which is short and broad ; on the other hand, in the Pediculus it becomes long, narrow and slender. The mandibles become true biting jaws, while in the Pediculus they become long and slender ; the maxillae become minute 1887.] ^^* 1 Packard. and sliort, of the masticatory type in the Mallophaga, while in the Pedi- culus they remain large and long (Meluikow, Fig. 371) and of the size and shape of the mandibles ; the second maxilhc in Pediculusare, in this stage, as large as iu the first maxillae, -while in the ]\Iallophaga they become minute. After the stage indicated by Melnikow's Fig. 37 (Pediculus) and Figs. 32, 33 and 34 {Trichodectes canis) the ordmal differences become more marked. Among the Pscudoneuroptera of Erichson, a group which is so unnatu- ral that it will have to be abandoned, we have after the elimination of the Odonata and the Plectoptera or Ephemeridaj, the families of Perlida;, Psocidiv, EmbidaJ, and Termitidoe, which we have associated together in the order Plutyptera. It is to the wingless Psocidae that the Mallophaga appear to bear the closest resemblance. If we compare certain 3Iallo- phaga, especially those with a small prolhorax, such as Goniocotes, Doco- phorus, etc., with the wingless Atropos, or the wingless young of Psocus, there is a general similarity to the latter in the small thorax, the large oval abdomen and the large head, with the small eyes. But these resem- blances are superficial. But, however, with the aid of Grosse's figures of the mouth-parts of the Mallophaga and Mr. E. Burgess' excellent fig- ures of the mouth-parts of the Psocidai*, three of which we reproduce, we find an unexpected homology, which shows that the Mallophaga are, so to speak, degraded Psocida;. One characteristic of the Mallophaga, in general, is the greatly enlarged front or clypeal region of the head, which is vaulted and conceals from above the mouth-parts, and sometimes even the antennae, with the occa- sional exception of the labial palpi. In the bird-lice, the lower, rounded edge of this circular clypeal region is applied to the surface on which the animal rests, as seen in Figs. 1 and 5, the labium and mouth-parts not being seen from above, except iu some genera where the maxillary palpi project lateral lj\ In the PsocidiE the position of the head is vertical, as seen iu Fig. 10, and the labrum is not covered by the clypeus ; but the ]\Iallophaga are unlike these and other insects in having the labrum covered by the cly- peus. In the shape of the mandibles the Mallophaga closely resemble the Psocidae, at least as much so as perhaps any oilier of the biting insects. Mr. Burgess has figured and described the first maxillae of Psocus (Figs. 10 and 11) and Atropos (Fig. 12). The cardo and stipesare rudimentary ; the latter bearlngbesides the four-jointed palpus a thick fleshy lobe homologous with the galea or outer maxillary lobe of other biting, ametabolous insects. He also describes at length the peculiar " fork," which has no homologue in the Mallophaga any more than other insects, Mr. Burgess inclining to the view that this is an independent organ. It is to be noticed that, with the exception of the palpi, the maxillae of the Psocidae are much atrophied. * The Anatomy of the Ilesid, and the Structure of the Maxilla in the Psocidte.

By Philip C, Garrett. {Read before the American Philosophical Society, October 21, 18S7.) Pliny Early Chase was a native of the old Puritan Commonweallh which has probably contributed more than any other to the intellectual life of this country. He was born at Worcester, Mass., on the 18th of August, 1820, and was descended on both sides from the hardy and intel- ligent yeomanry of Xew England, most of his ancestors in this country having been farmers. His father, Anthony Chase, wa5 for thirty-four years Treasurer of the county of Worcester and for tlnrly years President of the Worcester Mutual Fire Insurance Co., and died as recently as 1879 at the advanced age of eighty-eight years. His mother was Lydia Earle, of the neighboring town of Leicester. Her father, Pliny Earle, "made the first cards ever propelled by mechanical power in America, and invented a machine by which the manufacture of them was greatly facili- tated ;" Dr. Pliny Earle, one of the most distinguished alienists of this countrj^ was her brother ; another was Thomas Earle, an eminent philan- thropist, member of the Pennsylvania Constitutional Convention of 1887 and candidate of the Liberal Party for the Vice-Presidency in 1840 ; a third, John Milton Earle, was for many years Editor of the Massachusetts "Spy." The subject of this Memoir was of the eighth generation in descent from Ralph Earle, who " was on the island of Rhode Island in 1638, was one of the petitioners to the King for permission for the formation of a 'body politic' on that island, and was subsequentlj^amember of their legislative Assembly." Pliny Earle Chase's earl}^ education was received at the Worcester Latin School, the principal of which, at that time, Hon. Charles Thurber, afterwards member of the Massachusetts Senate, preceded his distinguished pupil to the " Silent Land " only a few days. Ex-President John Adams had been a teacher in the same school. Pliny afterwards attended the Friends' School at Providence, R. I., and entered Harvard in 1835, gradu- ating from that University in 1839 with the degree of A. B., and receiving that of A. M. in 1844. "As a boy, he was bright, intelligent, apt and quick in the acquisition of knowledge, but without special precocity. He was always one of the best scholars, but there was nothing that indicated the profundity of intellect manifested in his later years.'.' In a letter to his uncle, he writes, in his Freshman year : "I am chiefly guided in the path which I intend to pursue by an aspiration after such honors as are calculated to be of lasting benefit in forming an acquaintance with the ways of the world and in acquiring honorable fame." He was then only fifteen years of age, but his career would indicate that he kept this honorable ambition of his boyhood constantly in view throughout life. Edward Everett Hale, who was a Harvard classmate, informs that he was " distinguished for scholarship, especially for mathematical scholar- Garrett.] ^0*5 [Oct. 21, ship, in his class at Cambridge. He was one of a special advanced section in mathematics, of which no member had had to take a lesson a second time. They were therefore so much in advance of the great body of the class that, at the end of the mathematical course, they had the advantage of special instruction from Prof. Peirce in higher mathematics. He was interested in all branches of physics. I remember him especially," writes Mr. Hale, "as one of eight observers who made some of the first observa- tions which are on record of the shooting stars. The record will be found in the ' American Journal of Science,' of 1837, and I believe of the ' Comptes Rendus ' of the French Academy of the same year. He was a quiet, unob- trusive young man, but a favorite with the class from his uniform cour- tesy, and a rare sense of humor, which never left him through life." Upon taking his degree at Harvard, he immediately entered the pedagogic profession, at first in district schools in Leicester and Worcester, then in 1840-1 as Associate Teacher in the Boarding-school at Providence, in which he himself had prepared for College. In 1841-2 he taught at Friends' Select School on Cherry street, in Philadelphia, and, from 1843 to 1844, conducted a private school in the latter city. On the 28th of June, 1843, he married Elizabeth Brown Oliver, of Lynn, whose brother. Prof. James E. Oliver, of Cornell University, was a man of kindred tastes to his own. The following two years were spent in New England, where he prepared for publication his first book, the "Elements of Arithmetic, Parts I and II," afterwards published by Uriah Hunt & Sons, of Philadel- phia. This was followed, in 1848, by "The Common School Arithmetic." In the course of 1850, in connection with Horace Mann, he prepared and published " Mann & Chase's Arithmetic, practically applied," remodeling the 1st and 2nd parts of the "Elements of Arithmetic" into a new series, which was published by E. H. Butler & Co., Philadelphia. Dr. Thomas Hill, ex-President of Harvard University, bears the follow- ing testimony to the value of his arithmetical works : "Chase's Arithmetic was the best I ever saw. The two books 'Chase' and 'Chase & Mann, ' as we called them, were worth all other arithmetics that I ever saw put together. When I first introduced ' Chase ' into the public schools of Waltham, I had a hard battle with the committee and with the teachers. They thought it too difficult, etc., but, in less than one year, all were satisfied, and at the end of three years, all enthusiastic. No schools in Massachusetts, and I believe none in the world, equaled our Waltham schools in arithmetic. But the publishers sold the plates to a Boston firm, who had another and inferior book to push, and they melted up the plates of Chase, to my intense indignation." Stronger proof of their merit could scarcely be given. Dr. Hill regarded them not as compilations, such as the common run of arithmetics, but as original contributions to pedagogy, and "classed Mr. Chase not with mere compilers, but rather with the origina- tors, whose work is more akin to Pestalozzi's, and who deserve to rank very high ;" and probably no higher testimony could be produced than Dr. Hill's, on this point. 1887.] -^oJ [Garrett. la the fall of 1845, Mr. Chase returned to Philadelphia and conducted a private school for girls, at the same time giving lessons in other schools and in families. In all probability, he would have continued uninter- ruptedly in the pursuit of that profession, in which he was beginning to earn a measure of the "honorable fame " to which he aspired in his boy- hood, had not severe haemorrhages of the lungs, occurring three years later and continuing, with diminishing frequency, for ten years, compelled him to relinquish teaching. His physicians recommended a life which would allow of more out-door air and exercise, and he entered into a manufacturing business, under the name of North, Harrison & Co. Two years later, John Edgar Thomson, President of the Pennsylvania Railroad Company, joined the firm as special partner, and a younger brother of Mr. North as general partner, under the firm name of Norths, Harrison & Chase, who conducted a large foundry at Wilmington, Del., with sales-rooms in Philadelphia. In the following year, Mr. Harrison died, and the name was changed to North, Chase & North, and eventually Chase became the head of the firm of Chase, Sharpe & Thomson, the junior of which was Edgar L., a nephew of President Thomson. But although their house engaged in an extensive wholesale trade extending to foreign countries, tiie practical business element was somewhat deficient in the head of the house, who greatly preferred intellectual pursuits, and, after suffering heavy losses, he finally, in 1866, after having wasted eighteen precious years in uncongenial occupations, sold out his interest in the foundry business. He was at this time forty-six years of age. Prof. Chase has been criticised for too much diversification of pursuits. It was characteristic of this tendency, that for six or eight years prior to abandoning mercantile life, he had given private lessons in the then famous school for young ladies of Prof. Charles Dexter Cleveland ; and five years earlier bad actually bought the furniture and good-will of Prof. Cleveland, upon the hitter's retirement from teaching. This course, while more to the taste of so intellectual a man, did not conduce to the success of the foundry business which he was conducting, and which afterwards, in the hands of a former employe, proved exceedingly profitable, although the closing years of Prof. Chase's connection were the lucrative years of inflation caused by the war of the Rebellion. In the very same jj^ear, he also gave up the finishing school for young ladies, his own impression being that "the breaking out of the war interfered with private schools." He did not, however, abandon teaching, and from this time until his death adhered to his chosen profession, pursuing it continuously, if we except two visits to Europe, on the first of which, in 1870, he accom- panied a party of young ladies who had been his former pupils and who sought the benefit of his familiarity with the European languages, as well as his agreeable companionship. The second visit was made in the sum- mer of 1883 with members of his own family. His later da3's were certainly his best days as a teacher, and while a natural modesty stood in the way of ambition, and he preferred a quiet PROC. AMEU. PlIILOS. SOC. XXIV. 126. 2k.

On the sixteenth of January, 1863, he was elected a member of the American Philosopliical Society, to whose Transactions and Proceedings he afterwards became a diligent contributor. He occupied for a time the Chair at the University of Pennsylvania, rendered vacant by the death of Prof. Fraser, and, in 1871, became Professor of Natural Sciences in llaverford College, and remained a member of the faculty of that congenial institution until his death, occupying, after 1875, the Chair of Philosophy and Logic, then established. In 1876 he received the hon- orary degree of LL.D. from Haverford, on the ground of "his attain- ments and original researches in Mental and Physical Philosophy," Two years later, in the summer of 1878, after a severe illness, which resulted in the partial paralysis of one foot, and sensibly abated his physical vigor, he removed from Philadelphia to reside in the cottage on the beautiful grounds, in a bit of natural forest, adjoining the magnificent avenue of maples which forms the approach to Haverford College, On this charm- ing spot, in the midst of sweet pastoral scenes, abounding in vegetable life, he had an excellent opportunity to indulge his taste for botany, a favorite pursuit. In 1884 lie received the appointment of Lecturer on Psychology ^and Logic at Bryn Mawr College for Women. He prepared the syllabus and notes for the first course of lectures, which he was to have delivered in the winter of 1885-6, but was never able to deliver them, being overtaken by his final illness during that season. A sharp attack of pneumonia sapped the foundations of a vitality already much undermined, and although he partially recovered and resumed his duties at Haverford, the end was evidently drawing near. During the brief interval of life that remained and in consequence of the absence in Europe of his brother Thomas, who was President of Haverford College, he was made Acting President of that Institution, and held that position when death came, presiding at the Annual Commencement of 1886. His name had been prominently mentioned for the Presidency of Bryn Mawr College at the time of its organization, but the precarious state of his health forbade, although his eminent scholarship, the variety of his learning, and his pre- vious experience in Young Ladies' Schools, strongly commended him for that position. As a College Professor, he was clear in his demonstrations and attractive ; and many are the testimonies of affection and respect borne by his former students, accompanied by acknowledgments of the important influence of his teachings upon their lives. As a disciplinarian, he was mild and easy, inspiring his pupils with love rather than fear ; indeed the latter was not an ingredient in his system at all ; he governed purely by gentle suasion. Such is the simple record of a quiet life, the annals of which display no startling passages. If modesty were the opposite of greatness, then he was not great. But there was an unusual combination of great and good qualities in his mind and character, and one of its most conspicuous traits 1&S7.] 291 [Garrett. was a rare simplicity, indeed genuine modesty and humility, which is oftenest closely allied to a true greatness in the soul, unconscious of itself and busied with lofty studies of omnipotent power and sublimity. It was through this beautiful quality, wliich was perfectly natural and unassum- ing, that he endeared himself much to all of his intellectual associates, whether pupils or companions of his own age. lie had a singularly versatile mind, and a comprehensive and richly furnished memory. His writings included a wide range of subjects, upon each of which he displayed much erudition, and they were full of sug- gestivencss. It is seldom that a like capacity is found in one mind, both as a linguist and as a mathematician. He read with the help of dictiona- ries, and was more or less familiar with one hundred and twenty-three languages and dialects, and claimed thorough acquaintance with thirty of them. His knowledge of these was not profound, nor was it marked by the accuracy, in pronunciation and otherwise, which familiar conversation requires. Yet his attainments as a linguist afford a remarkable indication of the scope of his mind and the extent of his memory, and therefore throw an important light upon our estimate of the value of his deeper and more characteristic productions. Occasional contributions to the Proceed- ings of the American Philosophical Society were made on subjects in Comparative Philology, as the paper "On Radical Etymology, " that on the "Mathematical Probability of Accidental Linguistic Resemblances,", on "Sanscrit and English Roots and Analogues," on the "Comparative Etymology of the Yoruba Language," and others. His reputation as an analyst was sufficient to induce the sending to him of an obscure cipher from the War Department for translation during the Rebellion, and, on another occasion, of a Coptic inscription. But although his philological attainments were in no wise mean, his pen was most fertile in other directions. Of over 150 papers contributed by him to various learned bodies, most of them to this Society, not more than one-tenth were philo- logical, and the remainder mostly in meteorology, cosmics and physics. Many of these were fragmentary, — studies, as it were, of great themes, — and in undigested groups ; they were unfinished, like Michael Angelo's marble groups, and needed the master's hand to give them the perfect expression intended. As he grew older, they took more and more a cosmical direction, and his mind struggled to demonstrate from the har- monies of the universe, as the geologist does from the marvelous narrative of the rocks, a cosmical evolution. Going back to the very sources of development with daring genius, he sought, through proofs of the "Quantitative equivalence of the different forms of force which we call light, heat, electricity, chemical affinity, and gravitation," and original theories of nodal accumulation, the truth of which time may affirm, to establish a common law that "All physical phenomena are due to an Omnipotent Power, acting in ways which may be represented by harmonic or cyclical undulations in an elastic medium." A peculiarity of his mental operations was a singular capacity for seeing harmonies and analogies Garrett.] ■^•-'-' [Oct. 21, which did not attract the attention of others. His methods of thinking were swift, and led him to undemonstrated skips in his reasoning which made it difficult to follow him. In the ordinary processes of addition, he footed up columns of eight or ten nvimbers, extending into trillions, instantaneously, setting down the result from left to right, ending with the units. A certain instinctive or intuitive faculty pervaded his demon- strations, interrupting their purely mathematical character, and making many mathematicians and physicists plausibly skeptical as to the value of his theories. An eminent scientist at one time spoke of him as "the Kepler of this century," and there was a certain resemblance, in the tentative methods pursued by him, to those by which his great prototype discovered the astronomical laws upon which his fame is based. Prof. Kirkwood writes : " The just value of his contributions to science caiinot at once be determined. It must be said, however, that his hypo- thetical conclusions were so often in close agreement with well-known facts, as to leave the impression that his theories must have a foundation in truth." Prof. Herschell, referring to his paper on "The Results of Wave Inter- ference," bears this testimony : "From a direction of research probably as distant and distinct as pcssible from the late Prof. Chase's, at least in its origin, I have reached results which the contents in this case, of Prof. Chase's papers, confirm and corroborate so amazingly, that all question of the real validity of views, however incongruous they may perhaps be to each other in particulars, by which identical results of such surprising characters have been arrived at by us both, in perfect independence, is banished completely and forever from my mind. Prof. Chase's writings and discoveries will constantly gain in note and consequence by wider and longer consideration and perusal ; and they will surely never cease to have leading uses for consultation and for purposes of instructive study, among those who aim and strive to unmask more laws of energy's unitary opera- lions, if possible as prominent and predominating as those which his discoveries have disclosed." An American philosopher, who, while somewhat uncertain how to esti- mate him, says he is hopeful that the future will reveal the value of Prof. Chase's labors, speaks thus of his later work : " It may prove prophetic of developments that will take us a long step below our present philos- ophy of things — or it may not. Time will show. If the new develop- ments do come, my feeling is, that they will help to bring the heavens and the earth nearer together, by showing that beneath the seemingly ulti- mate facts of matter, gravitation, conservation of work, things that may seem to pertain to no other life cf ours than this— tliat beneath these, and nearer to the ultimate reality, there lies an order of things that may well serve as the physical basis of this and the next life alike." Prof. Chase, although, as we have already said, very modest in his esti- 1887.] -"^"^ [Garrett. mates of himself, was confident that his conclusions pointed in the right direction. Yet he did not claim matliematical demonstration for his theories, and while his papers abounded in formulae, they were only partly mathematical even in form. There was an element of imagination, of speculation and of intuition. The harmonies are not always perfect, links are missing ; very probably some of them will prove to be accidental, while others, with their profound inductions, will remain firmly planted upon the rock of truth. Indeed, they have claims, not only to coincidence with the conclusions of other philosophers, derived from different data, and reached through other channels, but even to verification as tiredictions. Dr. Chase regarded the series of twelve papers contributed to the London, Ediuboro' and Dublin Philosophical Magazine as containing, to quote his own words, some of his "most important discoveries in confirmation of the nebular hypothesis, including nine verifications of intra -mercurial planets and of harmonies of solar and planetary rotation that he had pre- dicted some years prior to the discovery." These " verifications of intra- mercurial planets " should rather be designated " Confirmations from other sources of liis opinion predicting them." These special articles comprised the 1. Cosmical Activity of Light ; 2. Equilibrating Forces of the Solar System ; 3. Planetary Interaction ; 4. Our Binary Star and its Attendants ; 5. Correlations of Central Force ; 6. ^therial Nodes ; 7. Momentum and Vis viva ; 8. Undulation ; 9. Criteria ; 10. Radiation ; IL Watson's Intra- mercurial Planet ; and, 13. Predictions. The titles of these papers suffi- ciently indicate their cliaracter and his claims of original discovery, which are further elucidated by such others, appearing elsewhere, as "The Gamut of Light," "The Music of the Spheres," "The Beginning of Development," "Planeto-taxis," and "Photo-dynamic Notes." Regarding light as the primal manifestation of force, and the Almighty fiat, "Let there be light " as the order for movement in the cosmic element, out of which all the complex development of the universe has grown, he felt after and sought to discover the fundamental laws whose universal applica- tion might pervasively explain all material forms and forces. Thus his investigations were not limited to the relations of the great forces of light, gravity, electricity, etc., but his speculations on the harmonies extended to the laws which govern chemical affinity and to ordinary material things. This much may be said as to these investigations : that 1. Whatever may be the ultimate conclusions of Science as to the precise nature and extent of the evolution, there has been an evolution from the simpler and more comprehensive conditions of matter, into the more com- plex and multiform. 2. It is reasonable to suppose that this entire evolution has been in accord- ance with some general law. 3. The discovery of that law is probably within the reach of the human mind. It was after this law that Prof Chase was searching ; the character of his Garrett.] ^ J4: [-q^^ 21, mind was one that eminently fitted it for the investigation ; and future researches may show his work to have been founded in fact and correct inference, and that he was in advance of his age and above the heads of his critics. The respect in which his writings have been held in Great Britain has been attested by their publication in the "Philosophical Maga- zine." His essay on "The Numerical Relation between Gravity and Magnetism" received, in 1864, the Magellanic Premium from this Society. The detached and fragmentary character of his scientific productions, their real profundity, and the limited number of those who could follow him in his rapid evolution of tl\ought on these subjects, have led many scientific men to regard his speculations with doubt, and some, who had little or no personal acquaintance with their author, accord them no scientific value. But Prof. Chase was least of all a hypocrite or a charla- tan, and those who knew him best will most unhesitatingly recognize his deep sincerity. lie was an humble seeker after truth, with the lamp of a strong intellect. The obscurity of his logic belongs not altogether to the writer, but to his theme. There was nothing obscure about his ordinary style. When he wrote upon familiar topics it was clear and cogent, rising sometimes into flights of eloquence. It is to be regretted that he has not himself been able to put into compact and comprehensible form his studies on cosmical and molecular forces as applied to astronomical and inter- planetary relations, and no less the profound, though fragmentary notes, which his mind threw off in later scintillations. But they were not completed, and though much more than gropings after the facts of infinity, can not lay claim to perfect and final demonstration. Whatever title his name has to rank among the greatest on the rolls of science, however, no one who knew his work will deny him an eminent place. The loftiness of conception and inspiring suggestiveness of his writings, his extensive learning, his great industry and productiveness, his boldness and success in dealing with the problems of the unknown world, entitle him to distinction. Aside from his deeper and favorite themes, the range of subjects ably treated by his pen was notable. Among these may 1)e remarked such familiar topics as Bricks, Paper, Ink, Ceramics, Artificial Iron Works. Some of his rules for weather prediction were embodied by the U. S. Signal Service in its " Manual for Observers," and the observations of the Bureau have indicated the importance of anti-cyclonic storm centres, to which he first called attention. He claimed the discoveries of "a para- bolic connection between the nearest fixed star and the solar system, of harmonic undulations which have influenced the arrangement of planets and of spectral lines, and of the quantitative equivalence of the different forms of force." He made many observations upon rainfall, and in a series of papers, "demonstrated the meteorological influence of the moon," regarding "the evidence of important lunar modifications, both in the amount and in the frequency of rain, as unmistakable." 1887.] -^"^ [Garrett. A leading characteristic of Prof. Ch'ise was the quiet and unwavering faith with which he adhered to the Bible record, and to Evangelical Christi- anity. Through all mutations, throughout his active studies of the material world, and of the great forces of Nature, he was unshaken in his belief in the spirituality of religion, and its real and necessary relation to the same Omnipotent Power, who originated the cosmos. He accepted the Christian theory of salvation absolutely and without qualiticatiou as Divine. That which many scientists are led to doubt, seemed clear to him, and all f\icts were of necessity parts of one stupendous whole. He was a religious man, not only ])y intellectual conviction ; but the fruitsof piety \tere manifest in his daily life, especially towards its end, in an unaffected gentleness and sweetness of temper, a freedom from assumption, and a general submission of his actions to the Divine government and guidance. Wealth had few attractions for him, his tastes inclining him to count it loss if it interfered with science and religion, even if he had had any gift for accumulating, which he had not. Born in the Society of Friends, he held throughout life their belief, and of later years frequently preached to the little congregation at Radnor, of which the Haverford students and Professors formed a part. Nor was his pen idle upon religious themes, and those affecting the prosperity of the sect he loved. He read an able paper before this body on "The Philosophy of Christianity," and his lecture "On Denominational Education in the Society of Friends" was a lucid argument of much power in its favor. He was wont to press the view that God was ever acting on the soul of man to give it right direction, as well as in the phenomena of nature. His faith was not so much in doctrinal propositions, as in God himself, as revealed in Christ, in Nature, in History, and in Man's reason and conscience. But while firm in his own convictions, he was broad and charitable to others, and sought to find any ground of common truth upon which he and those who differed most widely from him could stand. His opinion was candid, and open daily, like Dr. Arnold's, to change with the advances and discoveries of science ; yet he always retained an abiding confidence that Science and Revelation would be found really to harmonize. His personal trust in a present Omnipotence enabled him to meet all the vicissitudes of fortune with a more than philosophic composure and content. While his philosophy was pervaded with religion, his religion was no less filled with philosophy, and the lustre of his life presents a shining example to those who survive him of evolution "more and more unto the perfect day," when at last the " mortal shall have put on immortality."

By Alfred B Taylor, A.M., Ph.M. {Read before tlie American Philosopliical Society, October 21, 1S87.) For many years strong and persistent efforts have been made by tbe advocates of tbe French metrical or decimal system, to have its use made obligatory in the United States, to the exclusion of the heterogeneous tables of weights and measures now existing. Its use has been legalized in Great Britain since 1864, and in the United States since 1866. " On the first of January, 1879, a new Act went into force," (in Eng- land) " by which it is made unlawful to buy or sell by other than impe- rial measures, and no provision is made for the adoption of the metric system."* Its progress in either country has been very slow. At the meeting of the British Association for the Advancement of Sci- ence in 1887, Mr. Ravenstein, of the Geographical section, while strongly advocating the metric system, stated that "while the English foot is used by 471 millions of people, the metre is used by only 347 millions of peo- ple." But the selection of a system evidently should not be made be- cause a greater number of people use the one or the other, nor on account of the cost of the change in money or in temporary inconvenience, but it should be made on the intrinsic merits of the system. The zealous votary of the metric S3^stem can acknowledge no defects ; the offspring of the world's best science, it must be as perfect as it is beau- tiful, and only prejudice, ignorance and stolidity can stumble on obstruc- tions, or refuse entire allegiance to its beneficent sway. The real difficul- ties in the way of its success are fully realized alone by those who have given a careful and unbiassed attention, not merely to the various schemes proposed for simplifying or harmonizing national weights and measures, but to the practical operation of such reforms when actually applied to the daily life of human masses. And thus it occurs that what to the enthu- siast is the foremost virtue of the French system, is, in the view of the thoughtful student of facts, its most insuperable disadvantage. The objections to it have been suflicient up to the present time to pre- vent its adoption, and it is the opinion of very many persons that it can ■ never be satisfactorily adopted. Many different projects in remedy of the existing and acknowledged evils have been suggested ; some more practicable, others more systematic ; and unfortunately these two classes appear to bear an inverse ratio to each othei". The substitution of decimal multiples aud divisions, conformably to our established arithmetical notation, has been advocated ; and various stand- ards or units have been proposed, such as the inch, the foot, the grain, the * " New Remedies," Vol. viii, p. 192. New York, 1879. 1887.] 297 [Taylor. pound, the pint, tlie gallon, the cubic inch, the cubic foot, etc., but none of these projects has met with much favor. The most feasible plan for arriving at a satisfoctory and authoritative determination of so vital an issue would appear to be the appointment of an international commission, with England, Russia and the Germanic States (with France as well, if practicable), comprising the highest representa- tive talent, not alone from the ranks of the physical philosopher and geo- metrician, but as well from the classes of merchants, machinists and civil engineers ; from those most interested and most skilled in the subject, for the purpose of organizing and developing an acceptable and permanent sj'stem of weights and measures. Among the labors of such a commission, a very needful one would be to institute a careful and impartial investigation into the exact state and working of the metric system among those nations which had tried it. Assuming nothing, rejecting nothing, accepting nothing, as the ground- work of the future, the commission should endeavor, from a comprehensive survey of all the conditions and all the possibilities involved, to elaborate a scheme best suited to the wants of man, and therefore best entitled to the acceptance of the nations. If the final verdict were in favor of a uniform octonary system, it would not be difficult to establish it. If, on the contrary, such a commission should agree to adopt the present French system, their decision would go far to silence all further discussion ; the result would be well worth the labor and delay it might cost. No people would receive the system with greater alacrity, or master its details with more facility and promptitude than those of the United States ; not merely from their general intelligence and mental versatility, but from their long training in the use of their decimal monetary system. Such a conference among nations having so manj^ fraternal ties, seems to be eminently proper in every sense, and surely will not be regarded, at this day, as a visionary or illusive expectation. The origin of weights and measures is not known, and can be only con- jectured. Their need was contemporaneous with the inflmcy of the human race. Man in a slate of nature w^ould, in his strife for existence, seek food, clothing and shelter from the inclemency of the weather. He would kill animals for their flesh, and use their skins for clothing. Tlie adaptation of skins to this purpose would require measures of some kind to be used. Those naturally suggesting themselves would be the finger, the breadth of the hand, the span, the cubit (or extent from the tip of the elbow to the end of the middle finger), the arm, and the fathom (or extent from the extremity of one middle finger to that of the other, with extended arms). So in the construction of a habitation, however rude, whether of logs, or of earth and stones, he would find need for the use of measures, and some of the above would no doubt suppl}^ his needs. Distances traversed in his walks about his habitation would naturally suggest to him measures PROC. AMER. PHILOS. SOC. XXIV. 126. 2l. PRINTED NOV. 21, 1887. Taylor.] '^"t> [Oct. 21, of length, and none of those mentioned would conveniently supply liis want. Here he would probably use the foot or the pace, and it would not naturally occur to him to use the same measure, or the same scale of pro- portions and numbers to clothe his body and to mark the distance of his walks. Here, then, is a source of diversity in the standards of linear measure, flowing from the difference of relations between man and physi- cal nature. It would be as inconvenient and unnatural to measure a bow and arrow, for instance (among the first implements of solitary man), by his foot or pace, as to measure the distance of a day's journey, or a morn- ing's walk to the hunting ground, by his arm or hand. These natural standards are never lost to individual man in any stage of society. There are probably few persons living who do not occasionally use their own arms, hands and fingers to measure objects which they handle, and their own pace to measure a distance upon tlie ground. The need of measure^ of capacity would not be felt at quite so earlj' a period of man's history as measures of length, yet they would be rendered necessary by the nature of liquids, and for the admeasurement of those substances which nature produces in multitudes too great for numeration, and too minute for linear measure ; of this character are all the grains and seedSj which from lime to time, when man becomes a tiller of the ground, furnish the principal materials of his subsistence. But nature has not furnished him with the means of supplying this want, in his own person, and as his first measures of capacity he would probably employ the egg of a large bird, the shell of a mollusk, or the horn of a beast. The want of a common standard not being yet felt, these measures would be of vari- ous dimensions ; nor is it to be expected that the thought would ever occur to tlie man of nature, of establishing a proportion between the size of his arm and his cup, of graduating his pitcher by the size of his foot, or equalizing its parts by the number of his fingers. The necessity for the use of weights comes still later. It is not essential to the condition or comforts of domestic society. It presupposes the discovery of the prop- erties of the balance ; and originates in the exchanges of traffic after the institution of civil society. It results from the experience that the com- parison of the articles of exchange, which serve for the subsistence or the enjoyment of life, by their relative extension, is not sufficient as a crite- rion of their value. The first use of the balance and weights implies two substances, each of which is the test and standard of the other. It is nat- ural that these substances should be the articles most essential to subsist- ence. They will be borrowed from the harvest and the vintage ; they will be corn and wine. The discovery of the metals, and their extraction from the bowels of the earth, must, in the annals of human nature, be subsequent, but proximate, to the first use of weights ; and when dis- covered, the only mode of ascertaining their definite quantities will soon be perceived to be their weight. That they should themselves immedi- ately become the common standards of exchanges, or otherwise of value and of weights, is perfectly in the order of nature ; but their proportions to 1887.] ^y«^ [Taylor. one another, or to the other objects by which they are to be estimated^ ■will not be the same as standards of weight and standards of value. Gold, silver, copper and iron when balanced each by the other in weight will present masses very different from each other in value. They give rise to another complication, and another diversity of weights and measures. The balance, or scales, in a rude form, are known to have been in use from very early times. The Greeks, as appears from the Parian chronicle, be- lieved weights, measures, and the stamping of gold and silver coins to have been alike the invention of Pliidon, ruler of Argos, about the mid- dle of the eighth century B. C. The weights or counterpoises used in weighing were probably obtained by taking equal bulks, roughly determined, of some material of compara- tively uniform density, such as brass or iron ; but to render them more accurate and definite it became necessary to call in the aid of more accu- rate measures of capacity ; and the weight of a known volume of pure water, at a known density, is now the criterion universally resorted to for determining the standard of weight. This supposes that the volume or cubic contents are correctly known ; and since contents or capacity can be practically expressed onlj^ in terms of the cube of a length, and area in terms of the square of a length, it follows that to obtain exact units of measure of all kinds, it is necessary first to fix, and then to be able to reproduce with the greatest possible exactness, the unit of length. Absolutely invariable standards of weight and measure have not been, and in the nature of the materials to be dealt with, cannot beattained ; while to secure and reproduce measures of given sorts, the results of which shall be correct and uniform to within the least practicable degree of variability, is a problem upon which a vast amount of scientific research, ingenuity and labor has been ex- pended. When the legislator has the subject of weights and measures presented to his contemplation, and the interposition of law is called for, the first and most prominent idea which occurs to hira is that of uniformity ; his first object is to embody them into a system, and his first wish to reduce them to one universal common standard. In England, from the earliest records of parliamentary history, the statute books are filled with ineffectual attempts of the legislature to es- tablish uniformity. Of the origin of their weights and measures, the historical traces are faint and indistinct ; but they have had from time immemorial, the pound, ounce, foot, inch and mile, derived from the Romans, and through them from the Greeks, and the yarcl, or (jirth, a measure of Saxon origin, but as a natural standard diflereut from theirs, being taken not from the length of members, but from the circumference of the bod}"-, and hence a source of diversity. The yard, however, very soon after the Roman conquest, is said to have lost its original character of girth ; to have been adjusted aa a standard by the arm of King Henry the First ; and to have been found Taylor.] dUU [Oct. 21, or made a multiple of the foot, thereby adapting it to the remainder of the system. In 1266, the first positive attempt was made to change the common weight into the troy,* under the name of the weight of assize ; a statute 51. Henry III enacted "tliat an English penny called a sterling round, and without any clipping, shall weigh 33 grains of wheat, from the mid- dle of the ear, and 20 pence to make an ounce, 12 ounces a pound, 8 pounds a gallon of wine, and 8 gallons of wine a bushel of London, which is the eighth part of a quarter." This penny weight was divided into 24 grains. But neither the present avoirdupois, nor troy weights, were then the standard weights of England. The foundation of the sj^stem of 1266 was the penny sterling, which was the 240th part of the tower pound ; the sterling or easterling pound which had been used at the mint for centuries before the conquest, and which continued to be used for the coinage of money until the eighteenth j'ear of Henry the Eighth, 1527, when the troy pound was substituted in its stead. Tlie tower pound weighed 3G0 grains (or y\^) less than the pound ivoj, and the penny, therefore, weighed 22^ grains troy. Tlie philosophers and legislators of Britain have never ceased to be occupied upon weights and measures, nor to be influenced by the strong desire for uniformity. They found a great variety of standards differing from each other, and instead of searching for the causes of these varieties in the errors and mutabilitj^ of the laws, they ascribed them to the want of an immutable standard from nature. They felt the convenience and the facility of decimal arithmetic for calculation ; and they thought it suscep- tible of equal application to the divisions and multiplications of time, space and matter. They despised the primitive standards assumed from the stature and proportions of the human body. They rejected the sec- ondary standards taken from the productions of nature most essential to the subsistence of man ; the articles for ascertaining the quantities of which weights and measures were first found necessary. They tasked their ingenuity and their learning to find, in matter or in motion, some immutable standard of linear measure which might be assumed as the sin- gle universal standard, from which all measures and all weights might be derived. In France their results have been embodied into a great and beautiful system. England and America have been more cautious. Among the earlier measures of length used by various nations are found such as the "finger's length," the "digit" (second joint of the forefinger), the "finger's breadth," the "palm," the "span," the " cubit" (length of forearm), the "nail," the " orgyia " (stretch of the arms), the "foot," the "pace," etc., and the names of these measures, * When the troy weight was introduced into England is not known. It was iutrod-jced into Europe from Cairo in Egypt about the time of the Crusades, in the 12th century. Some suppose its name was derived from Tmyes, a city in France, which first adopted it ; Others think it was derived from Troy-novant, the former name of Loudon. 1887.] «jOJ- [Taylor. their almost constant recurrence among different nations, and the close approximation in length of such as have, like the foot, more nearly' ac- quired tiie cliaracter of arbitrary measuree, alike establish the fact tiiat in its origin, measurement of length was by the application of parts of the human body. In some parts of the East the Arabs, it is said, still mea- sure the cubits of their cloth by the forearm, with the addition of the breadth of the otlier hand, which makes the end of the measure ; and the width of the thumb was in like manner formerly added at the end of the yard by the English clothiers. Tlie advantages of such measures for pop- ular use are that they are known by observation and readily understood, and in an average way always capable of being recovered, when more arbitrary standards might be wholly lost. But their great disadvantage is extreme variableness, especial!}'- when directly applied ; and in the grad- ual progress of men's minds toward exactness of conception and reason- ing, three successive plans of insuring greater accuracy have been devised, and two at least have secured permanent adoption. The first is that of obtaining a uniform standard by exchanging the measures by parts of the body for conventional or arbitrary lengths, which should represent the average, and which were to be established by law. The second plan is that of making accurate comparisons of the various standards of each given sort in a country. Attempts of this kind appear in England to have been commenced under the auspices of the royal society in 1730 and 1742 ; in the former year by a comparison of the En- glish, French and old Koman standards ; and in the latter by the deter- mination (by George Graham) of the length of a pendulum beating sec- onds at London, to be equal to 39.1393 inches, and the construction of a standard j'ard. Of this, under the direction of the House of Commons, Mr. Bird (a celebrated optician) prepared two accurate copies, respectively marked "standard yard 1758" and " 1760," and intended for adoption as the legal standards. He determined and prepared also the pound troy, the original of that now in use. Of these two standards, no intentional alter- ation has since been made ; so that these or their derivatives are now in use in England and the United States. The third proposed step toward rendering measures exact has reference rather to the means of making the standards recoverable in case they should be lost. In the definite pursuit of this purpose the French philos- ophers of the time of the Revolution took the lead, and devised the metric system, in which the unit of length is derived from the dimensions of tlie earth, and the units of capacity and weight are made dependent upon the former, while the whole has decimal multiples and subdivisions. The celebrated commission concentred within itself the physical and mathe- matical science of France, but there was one science unfortunately not there represented ; the science of human nature. Looked at from a purely aritlimetical standpoint, the problem of measures suggested but one solu- tion, tliat of the decimal digits. Abstract mathematics could furnish no inducements to binary or octonary divisions or progressions. Taylor.] ^^-^ [Oct. 21, So early in our national existence as the year 1790, the illustrious Jeflfer- son, then Secretary of State, in obedience to a resolution of Congress call- ing upon the Secretary to propose a plan or plans for establishing uni- formity in the currency, weights, and measures af the United States, pre- sented a report recommending a decimal system of metrology, and its derivation from a natural and permanent standard of length. Instead of taking the ordinary pendulum of 39 inches, he proposed the second's rod of 5 feet, then generally known as Leslie's pendulum rod. A simple straight rod, without the bob or ball, suspended at one end, has, as is well known, its centre of oscillation at a distance of two-thirds of its length from its point of suspension ; or, in other words, is one-half longer than the common loaded pendulum vibrating in the same time. Such a rod vibrating seconds is 58.72368 inches long ; dividing this into five equal parts, Mr. Jefferson took this fifth part, or 11.744736 inches as the length of the new "foot," and from this by decimal multiples and subdivisions he presented a series of tables of weights and measures. When we reflect that the system of metrology here displayed was per- fected by Mr. Jefferson before any steps had been taken by the French government toward the decimal re-organization of weights and measures in that country, we must regard it as a memorial in the highest degree creditable to the judgment and contriving skill of its author ; and as one of many illustrations of the varied activity of his mind, and of the in- terest he ever felt in all schemes for human improvement. The great superiority of his proposed scales of measure, to those in common use, cannot be questioned ; and their adoption would have been a signal public benefit. The tables presented by him form a connected and complete sys- tem, each depending directly upon the one preceding, and necessarily flowing out of it, and all determined from a single and invariable natural standard by a very simple and beautiful mode of derivation. In this respect, however, the French system is by far the best of all that have yet been devised. Starting with a carefully measured quadrant of the earth's meridian, and dividing it into ten million parts, this system presents us with a "metre "* as a universal standard to which all others may be referred. Indeed, if a decimal system of weights and measures is to be ultimately adopted, there appears to be none that has such just claims to our acceptance as that of the French ; and although it would be much more difficult of popular introduction than a simple decimalization of our own divisions, and therefore less "practicable," there can be no doubt that it would be in every way superior, both in regard to the pre- cision of its measures, and the simple and philosophical character of its divisions ; besides all which it has the immense advantage of being already introduced and in successful practical operation throughout the great Re- public of France ; and every extension of its use would be an important step in the progress toward a uniform system among all nations. * Equal to 39.3707SS inches ; very nearly the length of the second's pendulum, and not much longer than our yard. 1SS7.] 'J'-'^ [Taylor. Beautiful and simple as this system appears, and clear as its nomencla- ture is to those familiar with the Greek and Latin tongues, it is j-et open to animadversion on practical grounds, in that its language is that of the philosoplier, and not of the tradesman or the business man. To all but classical scholars — that is, to the large majority of men — the terms used in the French tables are difficult and unmeaning ; to be acquired and appre- ciated only by a laborious effort of abstract memory, and even when thus acquired, constantly liable to be confounded and mistaken. Its metres and litres, its myriametres and myrialitres, its decigrammes and decagram- mes, are admirably contrived to bewilder the uninitiated, but of all possi- ble devices are the least adapted to the common uses of daily life. To obtain a ready and direct apprehension of the valuesof different denomina- tions of measure, it is necessar}' that each should be recognized as an in- dependent unit, without reference to its fractional or multiple derivation. Thus, "ounces" or "inches" are at once seized upon by the mind as dis- tinctive standards of value ; and the fact that these terms both signify "twelfths" (.being derived from the Latin "uncia") never enters into our contemplation when using them. The coin a "cent" has come to signify a "one" and not a "hundredth." "What is really needed then for the popular service, is a set of names, brief, easj^ and distinctive by a wide separation of sound, however arbitrary or unmeaning may be their origin. In this view of the matter, the rude and indefinite vulgarisms of "grains" and "scruples," "feet" and "rods," "gills" and "gallons" are in- finitely preferable to the scientific jargon of centigrammes and milUrjram- mes, and hectogrammes and kilogrammes. In fact, the French system has totally ignored all units, excepting the single one selected as the standard for each table. Thus in weight, the P*rench cannot be said to have any other measure than the gramme ; and instead of resorting to the dead languages for so familiar a thing as a simple numeration table, it would be much better to speak of and write down, the multiples or divisions of this weight as a thousand or a hundred grammes, or as so many hundredths or thousandths of a gramme. This, in plain English (or plain French), would be understood by every one, and would just as conveniently ex- press everything that is contained in the high-sounding terms we have characterized as "scientific jargon."* An almost unmanageable difficulty in the introduction of the French * While lluiti strongly e.xpressinf? our objection to the nomcndalarc of the French tables (whose very fault is its excess of system), it would be unjust not to acknowledge, and ungenerous not to admire, the catholic sentiment which dictated it. The eminent philosophers to whom belongs the honor of developing a metrology by far the most per- fect that has yet been devised, felt as if they were legislating for the civilized world. Desirous that all might have the benefit of their labors, they rejected all the familiar terms emi)loyed in France, and naturally re.-orted to the great storehouse from wliich the scientilic world has ever lieeti accustomed to ilraw its technical phraseology ; exhibit- ing in this, their anxiety to adopt a language which might be acceiitable to all nations. Unfortunately it is suited to none. The language of science cannot be that of the shop and the market-place.

Hence it is that the use of all technical language is excluded from social conver- sation, and from all literary composition suited to general reading ; from poetry, from oratory, from all the regions of imagination and taste in the world of the human mind. The student of science in his cabinet easily familiarizes to his memory and adopts without repugnance words indica- tive of new discoveries or inventions, analogous to the words in the same science already stored in his memory. The artist, at his work, finds no difficulty to receive or use the words appropriate to his own profession. But the general mass of mankind shrink from the use of unaccustomed sounds, and especially from new words of many syllables. Should these measures be therefore introduced, we should strongl}^ urge the entire abolition of the French nomenclature, and the complete natu- ralization of the dift'erent scales by the substitution of more familiar terms from our vernacular tongue. In tlie advancement of physical science no nation has taken a higher position, or exhibited a more fertile activity, than France. Hence it has become necessary for every English and American physicist to familiarize himself with the French units and standards of scientific research and discovery, if he would avail himself of their benefits or information. This again has induced a considerable employment of the same scales by the English and American savants, in repeating or extending the foreign experiments. It is not remarkable, therefore, that the scientific world generally, both in this country and in England, sliould desire to see this system universally prevail. Very few scientific men have given the sub- ject of popular weights and measures any special attention, and of those who have, it is believed that a very small proportion will be found to ad- vocate the unqualified adoption of the metric system. A decimal system applied to weights and measures must result in failure as regards the convenience of such a system or its adaptation to popular wants, and this want of adaptation arises, not from any defect in the plan on which it is established, but from inherent defects in tlie decimal system of numeration. The introduction of any new system of weights and measures, to take the place of one long established and in general use, will be found a trou- blesome and difficult exercise of legisUitive authority. There is indeed no difficulty in enacting and promulgating the law, but the difficulties of car- rying it into execution are always great. Of all the diffi( ulties to be overcome, however, perhaps the greatest is the abandonment of old and familiar units or standards. " Weights and measures maybe ranked among the necessaries of life to every individual of human society. They enter into the economical arrangements and daily concerns of every family. They are necessary to every occupation of human industry ; to the distribution and security of 1887.] ^t)5 [Taylor. every species of property ; to evehy transaction of trade and commerce ; to the labors of the husbandman ; to the Ingenuity of the artificer ; to the studies of the phih^sopher ; to the researches of the antiquarian ; to the navigation of the mariner, and the marches of the soldier ; to all the ex- changes of peace, and all the operations of war. The knowledge of them, as in established use, is among the first elements of education, and is often learned by tho.se who learn nothing else, not even to read and write. This knowledge is rivetted in the memory by the habitual application of it to tlie employments of men throughout life. Every individual, or at least every family, has the weights and measures used in the vicinity and recog- nized by the custom of the place. To change all this at once, is to affect the well-being of every man, woman and child in the community. It en- ters every house, it cripples every hand." The failure that attends the introduction, and the objections that have so far prevented the adoption of the metric system in Great Britain and in the United States, notwithstanding the strenuous and untiring efforts of its advocates, sufficiently attest the need of some other scheme, which, while possessing the advantages claimed by that, may be free from its dis- advantages and defects. Great Britain has shown such a determined opposition to the metric sys- tem, that, in the International Monetary Conference held in Paris in 18(i7, she refused even to negotiate in reference to unity of coinage, and her dele- gates stated 'that until it should be incontestably demonstrated that the adoption of a new sj'stem offered superior advantages justifying the aban- donment of that which was approved by experience and rooted in the hab- its of the people, the British government could not take the initiative in assimilating its money with that of the Continent." She maintains the most complex system of measures, weights and coin- age now In use among civilized nations ; she persistently rejects the deci- mal system and adheres to the complex division of pounds, shillings and pence, a system abandoned by the United States in their rejection of col- onial dependence. A very strong objection to accepting the metre, either directly or indi- rectly, as our national standard of length is the want of absolute precision in the rule itself. It has been shown by the investigations of able mathe- maticians, that the metre is not an exact expression of its theoretical value, and as the result of more extended geodetic measurement up to 1875, that the quarter of the meridian is equal to 10,001850 metres, and that consequently the metre is too short by ^^^q part of its length. This unfortunate and vital defect in the French metre nullifies almost en- tirely its value as a natural standard, and defeats the principal object of its establishment — the facility of its perfect restoration in all future time should the existing material standards be destroyed. The metre is just as arbitrary a standard as the yard ; the only real thing about it is the plat- inum rod in the public archives in Paris, and this has no advantage over the English standard kept in the British exchequer.

Our weights, measures and coins at present correspond much more nearly with the English than with the French standard. Our commerce with Great Britain is very much greater than with any other nation, and we should certainly commit a great error in adopting the metric system unless Great Britain should consent to adopt it also. Our adoption of the metric system, and the consequent change of our linear unit, would sever our uniformity with Great Britain, a country with -v^hich perliaps three-fifths of our foreign commerce is transacted, besides whicli it would entail great inconvenience and much greater ex- pense than is generally imagined. The measurements of every plot of ground in the United States have been made in acres, feet and inches, and are publicly recorded with the titles to the land according to the record system peculiar to this country. What adequate motive is there to change these expressions into terms which are necessarily fractional, and in which those foreign nations, whose convenience it is proposed to meet, have no conceivable interest? What useful purpose is subserved by designating a building lot 20 X 100 feet in the form 6.095889 X 30.479448 metres? Besides this, the industrial arts during the last fifty years have acquired a far greater extent and precision than were ever known before. Take, for instance, the machine shop, in which costly drawings, patterns, tajis, dies, rimers, mandrils, gauges and measuring tools of various descriptions, for producing exact work, and repetitions of the same with interchange- able parts, are in constant use. It has been calculated that in a well- regulated machine shop, thoroughly prepared for doing miscellaneous work, employing two hundred and fifty workmen, the cost of a new outfit adapted to new measures would be not less than one hundred and fifty thousand dollars, or six hundred dollars per man.* Supposing full consent were obtained for using metric measures in all new machinery, how slow and difficult would it be to make the change. A very large proportion of work consists in renewing worn parts ; where, then, are the new measures to come in ? The immense plant of railway motive power in the United States is all made to inches and parts. At what time can a railway company afford to change the dimensions of the parts of a locomotive engine? At no time, because the change would require to be simultaneous in the whole stock. It is true that the old dimensions might be adhered to, and called by metric names, putting 0.0254 metres, or 25.4 millimetres for one inch ; but this would be only an evasion, not a solution of the problem. A practical defect in the working of this system, which has been demon- strated by experience, is its incapability of binary divisions ; a defect which of course attaches equally to every decimal scale ; and one which * "The Metric System in our Worksliops," etc., by Coleman Sellers. Journal of the Franklin Institute, Philadelphia, June, 1874. 1887.] ^^' [Taylor. has always strikingly displayed itself wherever this scale has been brought into popular use, for the estimation either of lengths, bulks, weights or values. In our own country'' the decimal scale has been applied only to the currency, and we find that in spite of the legal division of the dollar into tentlis, and its seeming establishment by the coinage and circulation . of dimes, tlie people persist in cutting it up into quarters, eighths, six- teenths, and even thirty-seconds, to the utter neglect of the coins actually established by law, and to the inconvenience, confusion, and loss, result- ing from the necessary involvement of interminable and unmanageable fractions. For all the transactions of retail trade the eighth and sixteenth of a dollar are among the most useful and convenient divisions, and although our government has never coined them, their want has been continually felt, thereby showing the insufficiency of our much admired and boasted decimalization of moneys to meet the actual wants and necessities of trade and daily business life. So far, therefore, from our decimal currency pos- sessing the excellencies that have so often and so inconsiderately been ascribed to it, it has but the single merit of facility of computation. A single division of the number 10 brings us at once upon a prime number; and as the twelve pennies of the English shilling are far more convenient to the tradesman, than the 10 cents of the American dime, so the 12 inches of our present foot can never be usefully replaced b}^ the 10 centimetres of the decimetre. Many have supposed that this is all a matter of practical indifference, and that it merely requires the decisive sanction of legislative authority to accustom a people to any set of subdivisions. Such an opinion, however, exhibits both a blindness to the lessons of all experience, and an inatten- tion to many of the most important and subtle theoretical considerations affecting the relations of value and our apprehension thereof. Binal progression may be regarded as pre-eminently the natural scale of division. This fundamental fact is indeed illustrated in the very origin of the word division. The binary scale is in the first place the lowest and simplest of all tlie geometrical progressions. It is that of which we have the most ready and precise conception ; indeed, it may be said to be the only one of which we have any accurate appreciation be- yond the second or third term.* It is that by which we most rapidly and nearly approach any vague quantity we may desire to employ ; hence its universal use in trade. It is that which in any system of indepen- dent units of measure (as in weights, or coins) furnishes us with the means of representing the greatest range of particular values, by the smallest number of pieces. It ia that which aUbrds us the easiest prac- tical measure ; thus we can fold a string, a sheet of paper, or any other flexible material, or we can cut an apple, or a loaf bread, at once and * Thus, 1, 2, 4, 8, 16, 32, 64, etc., cfiii be readily apprehended as repeated doublings, while 1, 3, 9, 27, 81, etc., leave the mind confused in the attempt to follow up successive triplings, Taylor.] ^^8 [Oct. 21, with great precision into halves, quaiters, and eighths, while we should have to make repeated trials to divide the same into thirds or fifths, and then attain the result only tentatively and approximately. And lastly, it appears to be the most natural of scales, from the very common use of the two hands in separating objects into pairs.* Such being the claims, then, of the binary scale of geometrical progres- sion, and such its obvious advantages over all others, it is not surprising that this should be found to be practically the prevalent mode of distribu- ting the more common weights and measures throughout the world, what- ever may be the multiples or divisions enacted by law. The .Roman weights in general use throughout the empire (that is, throughout the civilized world) for some centuries after the Christian era, were by means of intermediate subdivisions (introduced by the common consent of traders) practically distributed upon a binary scale. So with the divisions in universal use at the present day ; we find that a nest of avoirdupois weights comprises ^ oz., ^ oz., 1 oz., 2 oz., 4 oz., 8 oz. and 16 oz., or 1 pound, and sometimes a 2-pound weight and a 4-pound weight ; and by this scale of binal progression or division, almost everything is purchased at retail. Our yardsticks are found to be divided not into the legal feet and inches, but into halves, quarters, eighths and sixteenths. Precisely so with the inch, which is never divided into its primitive "three barleycorns," but almost always, like the yard, by the binal scale into eighths and sixteenths, though occasionally divided for particular purposes into twelfths, or into tenths. The operation of this great law is quite as strikingly exhibited in France, where the popular necessities have compelled the introduction of binal divisions, not recognized by the estab- lished decimal scales, nor, indeed, strictly compatible therewith. Mr. Peacock, in his admirable treatise on "Arithmetic," in the Encyclo- pedia MetropolUana, thus sums up his review of the French system : " The decimal subdivision of these measures possessed many advantages on the score of uniformity, and was calculated to simplify, in a very extraordinary degree, the arithmetic of concrete quantities. It was attended, however, by the sacrifice of all the practical advantages which attend subdivisions by a scale admitting of more than one bisection, which was the case with those previously in use ; and it may well be doubted whether the loss in this respect teas not more than a compensation for every other gain." This deliberate judgment is from the author of perhaps the * " The classification by pairs which nature points out would suggest the simplest mode of reckoning. Counting these pairs again by two, and repeating the procedure, we arrive by progressive steps at the radical terms, 4, 8, 16, etc." {Edinburgh Revinv for May, 1811, Vol. xviii, p. 185). The celebrated Leibnitz, so eminent as a mathematician as well as a philosopher, struck with the simplicity and peculiar capabilities of this scale, proposed and strongly urged the introduction of Binary Arithmetic. He showed that the Binary system, in addition to its extreme facility, possessed peculiar value in discovering the properties of numbers, and in constructing tables, etc. He did not, however, recommend it for gene- ral use, from the increased number of figures required to express ordinary amounts. 18S7.] <^0" [Taylor, most thorough and philosophical treatise on arithmetic in our language, and such a statement certainly deserves our most serious consideration. The masterly and comprehensive report on the suhject of weights and measures, made to Congress in 1821 by Mr. Adams, when Secretary of State, contains the following judgment : "The experience of France has proved that binary, ternary, duodecimal and sexagesimal divisions are as necessary to the practical use of weights and measures, as the decimal divisions are convenient for calculations resulting from them ; and that no plan for introducing the latter can dispense with the continued use of the former. * * * From the verdict of experience, therefore, it is doubt- ful whether the advantage to be obtained by any attempt to apply deci- mal arithmetic to weights and measures, would ever compensate for the increase of diversity which is the unavoidable consequence of change. Nature has no partialities for the number ten ; and the attempt to shackle her freedom with them will forever prove abortive." So in the interesting paper of Dr. Ellis (in the American Journul of Pharmacy, Vol ii, page 202), the French decimal system is thus referred to : "Everyone is struck, at the first glance of this system, with the beautiful simplicity which it derives from decimal arithmetic. It appears, however, to have been overlooked, that, afthough decimal arithmetic is admirably designed to facilitate the calculation of mere number, it is not equally well suited to the divisions of material things." Much to the same effect has been the result of the commission appointed lately in England to consider the subject of a decimal coinage. The com- missioners, after a full discussion and investigation of the subject, have very recentlj^ reported against any change ; their report being drawn up in the form of a series of twelve resolutions. The seventh resolution is as fol- lows : "That as regards the comparative convenience of our present coin- age, and of the pound and mill scheme, for the reckonings of the shop and the market, and for mental calculations generally, the superiority rests with the present system, in consequence, principally, of the more convenient divisibility of 4, 12, and 20, as compared with 10, and the facility for a successive division by 2 ; that is, for repeated halving, in cor- respondence with the natural and necessary tendency to this mode of sub- dividing all material things ; and with the prevalence of binary steps in the division of our weights and measures." In the view, then, of this pervading law or principle of all human me- trology, so well established, and so distinctly recognized, it becomes an obvious necessity, in adopting a decimal scale, to engraft upon it, the divisions of halves and quarters, at least (and in the case of the more commonly employed units, of eighths), if we would adapt it to the de- mands of the people, or if we would hope for its permanent establish- ment. It is true that this would involve a considerable number of sub- ordinate divisions between one denomination of measure and the next be- low it, as it would be requisite to have separate and distinctive weights, for instance, for the unit (whatever it might be) for one and a quarter of Taylor.] olO [Oct. 21, the unit ; for two, for two and a half, and for five ; and it is also true that the fractional values thus introduced would not be directly referable to the ordinary computations of decimal arithmetic — thus adding, somewhat, to the complexity and trouble of otherwise very simple calculations ; but this is a fault, not of the binary divisions themselves, but resulting from a radical and incurable defect in the decimal system. So long as we con- tinue to count, to add, subtract, multiply, and divide by tens, so long must we submit to this inconvenience (undoubtedly a serious one) or we must choose the greater evil of abandoning all attempts at uniformity and consistency of system, and continue, as heretofore, to measure and to weigh by heterogeneous tables, while we perform the necessary opera- tions of comparing, compounding, and distributing these values, by a method or ratio entirely dissimilar ; entailing upon ourselves the waste of time, labor, and patience, consequent upon a petty scheme of eternal and superfluous reductions.* This horn of the dilemma is that which has been accepted by the coin- age commission of England, to which a reference has just been made. The eleventh resolution of the Commissioners' Report is : "That the ad- vantages in calculation and account keeping, anticipated from a decimal coinage, may, to a great extent, be obtained without any disturbance of our present coinage, by a more extensive adoption of the practice now in use at the National Debt Ofiice, and in the principal assurance oflQces, viz., of reducing money to decimals, performing the required calculations in decimals, and then restoring the result to the present notation," With our experience of a decimal coinage (notwithstanding its imperfections), this is not the horn likely to be selected 1)y Americans in attempting a reform in weights and measures. An expedient has been suggested by some, for facilitating division in decimal notation, which is ingenious, and deserves a notice. The project is to adopt a uniformly decimal system of weights and measures, but to estimate entirely bj' "cents" — by simply suppressing every alternate denomination ; thus, while reckoning decimally, we should traffic only centesimally. Our practical application of this method in all our money transactions, in which dimes are entirely suppressed in the market (though still having their place in the columns of the ledger) and our estimates made In dollars and cerits, familiarizes our minds to the process, and ena- bles us to see how such a system might be indefinitely extended, by the simple device of counting by double places of figures. The French table of weights would stand thus : 100 deci-milligrammes make 1 centigramme. *" Perhaps it may be found by more protracted and multiplied experience, that this is the only ' uniformity ' attainable by a system of weights and measures for universal use ; that the same material instruments shall be divisible decimally for calculations and accounts ; but in any other manner suited to convenience in the shops and markets ; that their appropriate legal denominations shall be used for comiiutation, and the trivial names for actual weight or mensuration " (Adams's Report). 1887. J 311 [Taylor. 100 centigrammes make 1 gramme. 100 grammes . " 1 hectogramme. 100 hectogrammes " 1 myriagramme. This suppression of the alternate denominations would have the advan- tage of abolishing the very objectionable terms decigramme and deca- gramme. Instead of the extreme awkwardness of taking one quarter of a gramme (2^ decigrammes), we are furnished with the value in whole units, by taking twenty-five centigrammes, just as we say twenty-five cents instead of two and a half dimes. Simple and taking as this proposal is, it is not free from serious objec- tions. It. in fact, complicates rather than simplifies, by giving a very wide range for estimating values. While it thus multiplies the units, and enlarges the interval between them tenfold, it only furnishes us with a single additional bisection, namely, the quartering. An eighth would still require a fractional expression. Its benefit, therefore, bears no propor- tion to the increased trouble and confusion involved. The necessity uni- versally felt for quaternal and octaval divisions, would infalliblj^ operate here as it has in our currency ; and we should constantly hear of 37^ hundredths of a pound ; 02^ hundredths of a pint, etc., which would be, in no respect, better than 3| tenths, or %\ tenths. The truth is, we need more frequent denominations than decimal ones, rather than more distant stepping-stones ; and for some purposes, even the binary ratio of progres- sion is not too slow.' In looking over the various tables of weights and measures prevailing throughout Europe, it will be found that a large ma- jority of the factors are 2, 4, and 8, with occasional resort to 3 and 6 — the number 4 being, perhaps, the favorite number for the more customary de- nominations.* Amid the conflicting claims of the numerous plans proposed for simpli- fying and uniting our incongruous metrology, there appears, at first sight, so much of irreconcilable contrariety, that it might be concluded that a combination of the respective advantages contemplated was hopeless and impossible ; and that we were only left to a choice of evils. A more care- ful scrutiny will however discover a pliilosophy in these very discrepan- cies, and furnish the elements of a practical concord. On the one side, the convenience of a system of divisions or multiples conforming exactly to that by which we are compelled to perform all arithmetical operations, is so obvious, and so universally recognized,! that the advocates of an entire decimalization are certainly justified in their zeal. On the other hand, the necessity of biual progression and division, though not so generally ack- * This is rendered very apparent on turning over the pages of Woolhouse's little work on the " Weights and Measures of all Nations."

Which policy must, then, be sacrificed ? "The elementary principle of decimal arithmetic," says Mr. Adams, "is supplied by nature to man within himself, in the number of his fin- gers. Whatever standard of linear measure he may assume in order to measure the surface or the solid, it will be natural to him to stop in the process of addition, when he has counted the tale equal to that of his fin- gers. * * * But while decimal arithmetic, thus for the purposes of computation, shoots spontaneously from the nature of man and of things, it is not equally adapted to the numeration, the multiplication, or the division of material substances either in his own person, or in external nature. The proportions of the human body, and of its members, are in other than decimal numbers. The first unit of measures for the use of the hand is the cubit, or extent from the tip of the elbow to the end of the middle finger ; the motives for choosing which are, that it presents more definite terminations at both ends, than any of the other superior limbs, and gives a measure easily handled and carried about the person. By doubling this measure, is given the ell, or arm, including the hand and half the width of the body, to the middle of the breast ; and by doubling that, l\ie fatJiom, or extent from the extremity of one middle finger to that of the other, with extended arms — an exact equivalent to the stature of man, or extension from the crown of the head to the sole of the foot. For subdivisions, and smaller measures, the span is found equal to half the ciibit, the palm to one-third of the span, and the finger to one-fourth of the palm. The cubit is thus, for the mensuration of matter, naturally divided into 24 equal parts, with subdivisions of which, 2, 3, and 4, are the factors ; while for the mensuration of distance, the foot will be found equal to one-fifth of the pace and one-sixth of the fathom " {Adams's Beport). "The fingers," says Dr. Lardner, "were naturally the first objects which presented to the mind the idea of number ; and they furnished, also, a set of natural counters by which the number of things might be marked and expressed. The fingers, being continually in view, familiar- ized the mind with the contemplation of every number of objects not exceeding ten. It was natural, therefore, that ten should be adopted as the number of objects to form the first group. * * * Although ten has been so generally adopted as the radix of systems of numera- tion, as to leave no doubt of its origin, yet it is not the only one which has been used, nor is it the only radix having a natural origin. The fingers of one hand rendered the number five familiar to the mind, before the conception of ten as a distinct number presented itself. It was even more natural and obvious, that the fingers should be contemplated aa 1887.] *^1^ [Taylor. two groups of five, than as a single group of ten" (Treatise on Arit7i- metic. Book i, chap, i, p. 5-6). The gradual and successive development of these scales, is so well set forth in Mr. Peacock's valuable treatise, that perhaps no apology is neces- sary for a somewhat lengthened extract from it, even at the cost of some repetition. "The decimal scale of numeration is not the only one which may be properly characterized as a natural scale. In numbering with the fingers we might, very naturally, pause at the completion of the fingers on one hand ; and registering this result by a counter, or by any other means, . we might proceed over the fingers of the same hand again, or with the fingers of the second hand, and register the result by another counter, or replace the former by a new counter which should become the rep- resentative of ten. * * * Again, the scale of numeration by twenties has its foundation iu nature, equally with the quinary and denary scales. In a rude state of society, before the discovery of other methods of numeration, men might avail themselves, for this purpose, not merely of the fingers on the hands, but likewise of the toes of the naked feet ; such a practice would naturally lead to the formation of a vicenary scale of numeration, to which the denary, or the denary with the quinary, or the quinary alone, might be subordinate. * * * Of other systems of numeration, the binary might be considered as natural, from the use of the two hands iu separating objects into pairs, and from the prevalence of binary combinations in the members of the human body ; but the scale of its superior units increases too slowly to embrace within moderate limits the numbers which are required for the ordinary wants of life, even in the infancy of society. * * * As the necessity of numeration is one of the earliest and most urgent of those wants which are not essential to the support and protection of life, we might naturally expect that the discovery of expedients for that pur- pose should precede the epoch of civilization, and the full development and fixing of language. That such has been the case, we shall find very fully and clearly established, by an examination of the numerical words of diflferent languages ; for, without any exception which can be well authenticated, they have been formed upon regular principles, having reference to some one of those three systems which we have character- ized as natural ; the quinary scale, whenever any traces of it appear, being generall}' subordinate to the denary, and, in some cases, both the quinary and denary scales being subordinate to the vicenary. In some cases, also, we shall find, from an examination of primitive numerical words conveying traces of obsolete methods of numeration, that the quinary, and even the vicenary scales have been superseded altogether by the denary" (Encyclopedia Meti'opoUtana, art. "Arithmetic," Vol. i, p. 371). Decimal arithmetic thus appears to be coeval and coextensive with the human race. It is, indeed, perhaps, the most universal of human insti- PROC. AMER, PHILOS. SOC. XXIV. 12G. 2n. PRINTED NOV. 21, 1887. Taylor.] dl4: [Oct. 21, tutions — at least as universal as language itself. From this universality, most writers have called it the "natural " system; but on examining the question whether the number ten possesses any intrinsic excellence or convenience to recommend it — any peculiar fitness as a ratio of geo- metrical progression, we find but one answer — it has none. It differs from any other number only in quantity, not in quality. So f\ir from its presenting any merit or advantage over its compeers, it is almost the last number which a true science of arithmetic would have selected for the important function of a radix of numeration. Its universality flows sim- ply from the fact that the necessities of man impelled a selection, in the very earliest infancy of the race, long before the invention of letters, and while yet a language was but slowly being formed ; and the selection comes to us stamped with the crude impress of a most irrelevant accident. Had the six-fingered giant slain by Jonathan (2 Samuel xxi, 20) lived early enough to be the father of the first unreasoning tribes, we should have had a duodecimal arithmetic ; or if, like the fowls of the air, we had usually but four toes to our extremities, we should now have been able to calculate only octavally ; and in either event we should have been much more skillful computers than we are at present. * Decimal numeration is "natural " then, only in the sense that ignorance is natural. The fingers have no more real or "natural" relation to the properties of number, than have any other organs or divisions of the human body ; and mathematically or philosophically considered, the digit is, therefore, no more a typical unit than a tooth (of which therp are thirty-two), or the leg of a spider (of which there are eight), or the petal of a flower (of which there may be any number). Nor have any but the most ignorant races — those without a literature and an alphabet — ever occasion to group and tally by their fingers. Only from unlettered savages could such a scale, therefore, have deen derived. It has been a favorite theory with a certain class of thinkers that primitive man was a highly civilized being — "a scholar and a gentle- man ;" and that the decay of states, and the decline of civilizations so unfortunately frequent in his history, but manifest his prevailing ten- dency to degeneration. Our universal arithmetic furnishes us with one of the most striking refutations of such a fancy. Wherever over the broad earth, the decimal scale exists, there have we the enduring monu- ment of the ancestral savage — counting by his fingers or his naked toes.f * " There can be no doubt that if man had been a twelve-fingered animal, we should now possess a more perfect system of numeration tlian we do. Whatever he the radix of the scale, it would always be a convenience to be able to subdivide it with facility, without resorting to the more refined expedient of fractional language'-' {Lardner's Arith- metic, chap, i, p. 21). t The German word for ten— se7«e;i— signifies "toes," being the plural of the word, x?ic. We do not generally or readily recognize this intellectual association in our own language; and yet the Saxon word— oint.

A very simple parallelogram is however afforded us, which gives with precision the dimensions of these respective areas. Thus a " district," as a land meas- ure, is a rectangular ^Dace of ground, measuring two furlongs in one direction, and four furlongs in the other; an "acre" a similar space of ground measuring two chains in one direction by four chains in the other; a "plat," a space measuring two rods in one direction, by four rods in the other ; and a " lot " is in like manner a surface of two Modules by four Modules. This table presents, therefore, the simplest ratios of superficial measure which could be devised ; and would be found admira- bly adapted to every purpose of mensuration.

In this re- spect our linear unit is very greatly superior to the Metre, which, from its inconvenient size, has been made practically a standard only of lengths. The Are (the unit of surface) is derived, not directly from the Metre, but from the Decam/itre ; the Litre (the unit of capacity) is derived from the cube of the Decimetre; and lastly, the Gramme (the unit of weight) is derived from the cube of the Centimetre. The greater sim- plicity of our project is manifest in this contrast. Table op Volumes. 1 cubic dent Cubic Feet.

Each of the cubic measures of the above table has for the dimensions of its side two of the linear values above it. The practical conveniences of simple and direct relations between lengths, weights, and measures of capacity are certainly too obvious and too great, to be lightly thrown away. Thus, where we are furnished with a measure, the root of whose cube is precisely a measuring rule in com- mon use (one of the many advantages which result from an octonary scale of weights and measures), the benefit is by no means trivial ; the farmer can always, without any calculation, make himself a cubical box (whether to supply, or to verify a measure) whose capacity shall bQ fully as accurate as the "bushel" he may purchase — even admitting that such a process may not have the precision that would satisfy the ex- perimental philosopher. And this is a benefit which would attach equally to every unit of measurement in the scale. Whenever so radical a change is contemplated as the introduction of new divisions or denominations of measure, the importance of adopting at the same time the most useful or convenient standards that can be devised, is too eminent to justify a moment's hesitation in throwing aside everything that has not some intrinsic value to plead for its preservation.

These 19 weights make a total of 14104 grains, and would consequently be sufficient to weigh any number of half grains from 1 to 282u8. Upon examiuation of the above table, it will be seen that the viite is very nearly equal to half a grain, the did'erence being xotVoo- ^^ about 3;igth of a grain ; two mites being about y\th less than one grain ; one carat is very nearly equal to 4 grains, being about 2^ grain less. One scrap is about 1^ grains more than the half drachm. One semy is 34 grains more than half an ounce avoirdupois, or 12J grains more than half an ounce troy ; while four utices are equal to 18^ ounces avoirdupois nearly. Of tlie fluid measures the Ugule is equal to half a fluid-drachm and 3.2 minims ; two Ufjules being 6.4 minims more than a fluid-draclim, or the medicinal teaspoon ful ; the cup is equal to 4 flaid-ounces and 3:^ fluid- drachms ; 4 gills are equal to 1 pint and If fluid-ounces, and the new quart is equal to two pints and 3^ fluid-ounces. The smaller of these weights and measures assimilate so nearly with our present divisions, that for most practical purposes in medicine, pharmacy, etc., the difference would be inappreciable. It is true that all the valuable knowledge that clusters about the grain weight, in statistics of all kind, would have to be recalculated in the new weights, but as has before been stated this is a necessary consequence of any alteration in our unit. If instead of retaining our linear unit, the inch, we had selected the grain weight, all of our weights would have been in even grains, while our measures would have been fractional quantities ; in this case, instead of taking the inch, we would take the length of one side of a cube of water weighing at its greatest density 256 grains ; such a cube would vary very slightly from a cubic inch ; its side would measure 1.004334 inches ; sixteen times this length would give us a "Module" equal to 16.069344 inches, and our " Fondus" would weigh 149 lbs., 12 oz. and 336 grains ; our "scrap" would be exactly 32 grains, our "carat" exactly 4 grains, and our "mite" exactly half a grain. It is believed that the scheme here proposed, independently of its merits, would less disturb our present system of weights and measures than any that has yet been proposed, and would be, therefore, more easilj'' intro- duced and willingly accepted. And has not the time arrived in the general progress of commercial and international intercourse, and the rapid advance of our country in science, wealth and power, when her voice should be heard in an important mat- ter like this ! Should not our Congress invite all nations to appoint suit- able persons to be their representatives in a universal convention to be as- sembled for the purpose of devising and establishing a system of uniform weights and measures, practically applicable to the need and use of all peoples of the earth ? 1887.] «>57 [Taylor. Such action could not fail to meet with a response due to the importance of the subject ; and if the great object be attained, to lead to results pro- ductive of vast and lasting benefit to the human race. These suggestions are offered for the purpose of promoting discussion, investigation, and consideration of the subject in all its bearings, in the liope that when the time arrives in which a change must be made, and such a time will inevitably come, that a system may be adopted which has been, or can be demonstrated to possess the greatest advantages, and is admitted to be, of all schemes proposed, the truest, the wisest, the best. Note A. "The triumph of the art of calculation, and that to which mainly the modern system of numerical computation owes its perfection, consists in the 'device of place,' by which all necessity for distinguishing the nature of the units signified by any symbol is superseded. Like many other inventions of the highest utility this, when known, appears to aiise so naturally and neces- sarily out of the exigencies of the case, tiiat it must excite unqualified as- tonishment how it could have remained so long undiscovered. » * * That the honor of the invention of a system which produced such important effects as well on the investigations of science as in the common concerns of commerce, should be claimed by many contending nations, is what would naturally be expected. * * * All Arabian authors on arithmetic appear to agree that the first writer of that country upon this system of arithmetic was ^lohamnied ben Mnza, the Khuwarezmite, who flourished about the year DOO. This writer is celebrated for having introduced among his countrymen many important parts of the science of the Hindoos, to the cultivation of which he was devotedly attached; and among other branches of knowledge thence derived, there is satisfactory evidence that this species of arithmetic was one. From the time of Mohammed ben Muza the figures and modes of calculation introduced by him were generally adopted by scientific writers of Arabia, although a much longer period elapsed before they got into com- mon popular use, even in that country. They were always distinguished by the name Ilindasi, meaning the Indian mode of computation. * » At the beginning of the eleventh century the use of the Arabic notation had be- come universal in all the scientific works of Arabian writers, and more espe- cially in their astronomical tables. The knowledge of it was of course com- municated to all those people with whom the IMoors held that intercourse which would lead to a community of scientific research. In the beginning of the eleventh century the Moors were in possession of the southei n part of Spain, where the sciences were then actively cultivated. In tins way the use of the new arithmetic was received into Europe first in scientific treati.ses. A translation of Ptolemy was published in Spain in 1130, in which this notation was used ; and after this period it continued in general use for the purposes of science. Xotwitiistanding the knowledge and practice of this superior notation by scientific men, the lioman numerals continued to be used for purposes of business and commerce for nearly three centuries, and it was only by slow and gradual steps that the improved notation prevailed over its clumsy and incom- modious predecessor. The first attempt to introduce it for the purposes of com- merce was made by a Tuscan merchant, Leonardo Pisano, in 1202. Having Taylor.] 358 |-Oct. 21, traveled in Barbary, he there learned the method of Hincloo arithmetic, and, struck with its superiority over that to which he had been accustomed, he determined that his countrymen should no longer be deprived of the benefits of it. He accordingly published his treatise in the Latin language ; in which he professes to deliver a complete doctrine of the numbers of the Indians. « » ■;■:- ^ considerable period, however, was necessary to introduce this system into the common business of life. The extensive commerce main- tained by the Italian States directed their attention to the subject at au earlier period than other nations ; and although, for scientific purposes, the date of the introduction of the Arabic numeration into Spain is earliei- than that of its appearance in Italy, yet its use for the common business of life prevailed at a much earlier period among the Italian States than in any other nation of Europe" {Lardner's Treatise on Arithinetic, Book i, cli. ii). The Hindoo numerals are found in various manuscripts of Italy bearing the dates 1212, 1220, 1228. But none are found in England till nearly two centuries later. Chaucer, the 'poet, who died in 1400, alludes to them in one of his poems as " the figures neice." According to Sir John Bowring (" Decimal System," pages 23-30), the first calendar in the English language in which the Hindoo numerals are era- ployed, bears the date of ='1431," and the earliest date known on a tombstone in these figures is "14.54," the tombstone being that of "Elen Cook," in the church at Ware. The first English book which bears its date in these figures is the " Bhetorica Nova, Gulielmi de Saona, 14V8." And in seals only one example has been found anterior to the sixteenth century, which bears the date 1484. "The Roman figures lingered longer in England," adds Bow- ring, "than in any other part of the European world, having found an asy- lum in the dark and dull regions of the Exchequer" (page 26). "It is in- deed scarcely credible that the perplexing and entangled manner of keeping accounts by the Roman numerals, in the same barbarous style which was practised before the Norman Conquest, was maintained at the Exchequer almost down to the present day. * * » In addition to this strange and absurd system of Exchequer book-keeping, tallies continued to be used down to the year 1782. It was only in the year 1831 that the Committee on Public Accounts, of which I was the secretary, recommended the utter and com- plete abolition of the ancient system and the adoption of the Indian numer- als. It Avas in consequence of this change that in the year 1835 the tallies were ordered to be burnt ; a conflagration which led to the destruction of both Houses of Parliament — the Exchequer in which the tallies were kept having formed a part of the ancient edifice of St. Stephen's" {Sir John Boicring's Decirnnl System, pages 124-125). Delambre regards it as a fact humiliating to the pride of himian genius that the discovery of the true notation of numbers by nine digits and zero shoidd have escaped the sagacity of the illustrious geometei s and mathema- ticians of ancient Greece. "The Hindoos," says Peacock, "consider this method of numeration as of divine origin. The invention of nine figures with the device of place being ascribed to the beneficent Creator of the uni- verse. Of its great antiquity amongst them there can be no doubt, it having been used at a period certainly anterior to all existing records" {Encyclope- dia Mctropolitana). It can be traced back with certainty at least four centuries before its appearance among the Arabs, and as Lardner well re- 1887.] 359 [Taylor. marks, since "none of these Hindoo authors claim either for themselves or their predecessors the invention of this method of enumeration, but always mention it as being received from the Deity, we may infer that it was prac- tised in that country beyond the limits even of tradition." The Indian ori- q,m of our numerals being thus so well established, there is a manifest im- propriety in continuing to designate them as the " Arabic figures," as is con- stantly done in our scliool arithmetics. Let as give honor wiiere honor is due. Note B. It is remarkable that this binary system, according to the opinion of many, was used in China, four thousand j'ears ago, by Fohi, the founder of the empire. A tablet of great but unknown antiquity, called the Cova of Fohi, marked with a series of variously broken lines, and held in superstitious reverence by the Chinese, as containing the mystery of a divine wisdom, has been found to be comi:)leteIy deciphered by the notation of binary arithmetic. When Leibnitz had extensively circulated his scheme or invention through the various scientific journals, and by means of his own correspondence — it appears to have found its way even to China, and to have attracted the attention of a Jesuit missionary at Pekin, named Bouvet. This ecclesiastic, engaged at the time in the study of the Chinese antiquities, discovered and immediately communicated to Leibnitz, with much exultation and enthusi- asm, the surprising fact that his system furnished a perfect kej' to the mys- terious lines upon the ancient Cova — hitherto inscrutable, or interpreted only by the speculations of the most extravagant mysticism. The lines of Fohi are arranged in an octagonal form, so as to make the ends approach ; each set of the eight series being disposed on a side of the octagon. These lines transferred from the Cova tablet, and placed in a straight line, are here represented. The row of figures in front expresses the value of each compound symbol, the other figures, which represent the binary notation, manifestly exhibiting a perfect correspondence with the symbols throughout. "These figures of eight cova," says Mr. Peacock, (in the Encyclopedia Met roj)oUtana), "are held in great veneration, being suspended in all their temples, and though not understood, are supposed to conceal great mysteries, and the true principles of all philoso- phy, both human and divine." This inscription is exceedingly interesting as ex- hibiting a true example of that philosophic notation, the device of the cipher— and the determination of value by place. The absence of any other traces of such a notation in China, and its well-known anti- quity in India, where it had been so fully elaborated, would lead to the suspicion that it was to this latter country that Fohi was indebted for this curious record of ingenious thought. It apjiears that Bouvet was fortunate enough to find, subsequently, a Great Cova, in which these markings were carried to a period eight times the extent of the Small Cova. In the Edinburgh Encyclopedia 0 1 1 1 000 1 1 001 2 010 3 on 4 ! 1 1 1 100 5 1 101 6 110 7 111 Taylor.] 360 [Oct. 21, (Article " Arithmetic"), it is stated in reference to this subject, tliat Fatlier Bouvet, wlio first sugge.sted tliis explanation and communicated it to Leib- nitz, afterward procured, during his residence in China, the Great Fi(jiir& of Fold, which extends as far as Gi. The exact coincidences which he still found to prevail between the combinations of these lines and the figures of the binary notation, left no doubt with regard to the justness of his conjec- ture ; and we cannot help remarking that the restitution of the true sense of those characters, after so long an interval of time, is a very singular fact in the history of science. Note C. It is interesting to trace the history of the gradual development, in modern times, of the grand but difficult project of obtaining from nature a constant and universal standard of length. It is obvious that no such objects of ulti- mate reference as the human foot, or arm, or cubit, or as "thirty-six barley corns round and dry," can be regarded as natural standards, since they are wholly useless for tlie purpose of any precise determination. And all meas- ures derived from them are purely arbitrary, as their authority is obtained from positive enactment, merely, and not from any agi-eement with their nominal originals. Hence it is not at all surprising that "cubits" and "feet" come to signify anything the civil power may enact ; the former of these denominations ranging through every gradation of value, from the covid of Wy^ inches to the royal Egyptian cnhit of 253^ inches, and the latter from the Pythic foot of 9% inches, to the Geneva foot of 19 inches. Nor would it ever be possible from such sources, to reproduce a lost standard, with even the rudest approach to exactness. As Mr. Adams has well remarked, "For all the uses of weights and measures in their ordinary application to agricul- ture, traffic, and the mechanic arts, it is perfectly immaterial what the natural standard to which they are referable may be. The foot of Hercules, the arm of Henry the First, or the barley-corn is as sufficient for the purpose as the pendulum, or the quadrant of the meridian" {Report to Congress). " The first attempt at fixing such a standard as should be accurate and universal, both as to place and time, is due to the inventive genius of the celebrated Iluyghens. That philosopher demonstrated that the times of the vibrations of pendulums depend on their length only. ® * •■■ Hence he con- ceived that the pendulum might afford a standard or unit for measures of length " {Edinburgh Eeview, Vol. ix, page 373). It was in his " Horologium Oscillatorium" (published about 1G70), that Iluyghens proposed the use of the seconds' pendulum as a universal and perpetual measure ; this length to be divided into three equal parts ; and this third part (about 13 inches) to be called the horary foot. The celebrated Picard, who first measured from Paris to Amiens in 1669, an arc of the meridian in France, making the degree equal to 68.94.5 miles (a measurement memorable as having furnished Newton with the means of verifying his grand theory, incapable of determination from the pre-existing data), also proposed in 1671, in agreement with the idea of Iluyghens, that the pendulum beating seconds should be adopted as the unit of length. Picard has the merit of having first thrown out the suggestion that the diur- nal rotation of the earth ought to affect the oscillation of the pendulum, and 1887.] ^^1 [Taylor. that it ouglit to vibrate more rapidly toward tlie poles than toward tlie equa- tor. He accordingly tried the pendulum at Uranibourg, at Paris and at Cette, but wab not fortunate enough to discover any sensible difference. Eoemer also found the length the same at London. Richer, however, in the same year, 1671, or early in 1672, wliile engaged in the duties of his commission at Cayenne, on observing the length of the sec- onds' pendulum at this place (lat. 4° 56' north of the equator), found it sen- sibly shorter than at Paris (48° 50' north), the difference being about aline and a quarter. Picher's discovery that the pendulum varied in length with the latitude, deprived it of that uniform character considered so necessary in a linear stdndard. The Abbe Gabriel Moiiton, a distinguished mathematician who flourished at the same time, appears to be the first who suggested a measure derived from the earth. He proposed, almost simultaneously with the publication of Huyghens, a decimal system of measit res hKsed on the value of a minute of arc, as derived from Piccioli's length of a degree. This minute of the degree he called a miliare, the thousandth part of which he called a virrja, equal to 5 feet 4'^ inches. We have here the germ of the present French metrology. Cassini, who in 1718 repeated the measurements of a meridian made by Picard (extending his arc, however, further south, namely, from Paris to Dunkirk, and making the degree 69.119 miles), proposed the earth's radias as the unit of length. He afterward in his book, " Be la Grandeur de la Terre," proposed as a unit the six-thousandth part of a minute of a degree of a great circle of the earth, a measure very nearly equal to the foot. In 1748 M. de la Condamine (who had recently returned from measuring a degree at the equator in Peru), in a memoir read before the Academy of Sciences, resumed the idea of the pendulum as the unit of length, proposing that it should be taken as beating seconds at the equator, as the most notable line of latitude, and as one likely to avoid all the prejudices which might arise from national jealousy were the latitude of any particular place selected. "We see from this the anxiety felt to secure a standard whicli might be com- mon and uniform among nations. On the 15th of January, 1790, in accordance with President Washington's recommendation, the House of Pepresentatives "Ordered, That it be referred to the Secretary of State to prepare and report to this House, in like manner, a proper plan or plans for establishing uniformity in the currency, weiglits and measures of the United States." On the 15th of July of that year the House of Representatives received from the Secretary of State (Mr. Jefferson) his report of the proper plan for establishing the desired uniformity, as requested by the House. In this elaborate report the Secretary proposed " that the standard of mea- sure be a uniform, cylindrical rod of iron of such length as, in latitude 45°, in the level of the ocean, and in a cellar or other place, the temperature of which does not vary through the year, shall perform its vibrations in uniform and equal arcs in one second of mean time." Starting from this standard, he proposes two distinct plans for the consid- eration of the House, that they might, at their will, adopt the one or the otlier exclusively, or the one for the present and the other for the future time, when the public mind may be supposed to have become familiarized to it. The first plan was to define and render uniform and stable the existing sys- PROC. AMEB. PHILOS. SOC. XXIV. 136. 2t. PRINTED DEC. 2, 1887. Taylor.] ^^^ [Oct. 21, tern; to make the foot to bear a definite ratio to tlie standard penduhim rod ; to reduce the dry and liquid raeasure.s to corresponding capacities by estab- lishing a single gallon of 270 cubic inches, and a bushel to be eqnal to eight (8) gallons, or 2,1G0 inches— that is, to one and one-fourth cubic feet; to make the ounce to be the weight of one-thousandth part of a cubic foot of water ; to retain the more known terms of the two kinds of weights in use, reduced to one series ; and to express tlie quantity of pure silver in the dollar in parts of the weight so defined. The second plan was to reduce " every branch to the same decimal ratio already established in coins, and thus bring the calculation of the principal affairs of life within the arithmetic of every man who can multiply and divide plain numbers." Except in the length of the fundamental unit, and in the nomenclature, this was essentially that of the metrical system of France. Tliese two plans were sharply opposed to each other, and it was to be ex- pected that the desire for a decimal division, and symmetry of system on the one hand, and the reluctance to make a violent change on the other, shouljl elicit no little discussion. This report was communicated to the Senate in December of that year and referred to a committee. That committee reported on the 1st of March, 1791, that, " as a proposition has been made to the National Assembly ,of France for obtaining a standard of measure which shall be invariable, and communicable to all nations and at all times; as a similar proposition has been submitted to the British Parliament in their last session ; as the avowed object of these is to introduce an uniformity in the measures and weights of the commercial nations ; as a coincidence of regulation by the Goveinment of the United States on so interesting a subject would be desirable, your committee are of opinion that it would not be eligible, at present, to intro- duce any alteration in the measures and weights which are now used in the United States." This report was adopted. In 1790, Talleyrand proiwsed to the constituent Assembly of France, that in view of the great diversity and confusion in the weights and measures of the country, a commission should be appointed for the purpose of consulting with a similar commission from the English Government, upon the subject of establishing a uniform international system of metrology, founded upon a single and universal standard. The proposal alluded to the only two natural standards which presented themselves, viz., the measure of the earth and the pendulum, and expressed a decided preference for the latter. The result of this movement was the appointment of Borda, Lagrange, Laplace, Monge, and Condorcet, as commissioners to examine into and report upon the sub- ject. After a careful consideration of the three plans submitted, namely, the pendulum, a quarter of the equator, and a quarter of the terrestrial meridian, they very judiciously agreed in decidedly recommending the latter ; regard- ing the pendulum as an unsuitable standard, whether taken at forty-five degrees of latitude or at the equator. The attempt to enlist the co-operation of England proved abortive. " The operation of changes of opinion there," says Mr. Adams, "is slow — the aver- sion to all innovations deep. More than two hundred years had elapsed from the Gregorian reformation of the calendar, before it was adopted in Eng- land. "•■■• * * After a succession of more than sixty years of inquiries and 1887.] ^t)D [Taylor. experiments, the British pavlianient have not yet acted in the form of law " (Reijort to Congress). Just five hundred years after the statute of 17th Edward II (A.D. 132-t), enacted that " three barley-corns round and dry, make an inch— twelve inches make a foot," etc., the first change was made in the legal definition of the foot. By the act of 5th George IV, c. 71 (1824), it is declared "the standard yard is the distance between the centres of the two points on the gold studs in the straight brass rod now in the custody of the Clerk of the House of Com- mons, whereon is engraved 'Standard yaid, 1760,' the brass being at the tem- perature of 62 degrees of Fahrenheit's thermometer." "The Yard, if lost, defaced, or otherwise injured, may be restored by comparing it with the pen- dulum vibrating seconds of mean time in the latitude of London, in a vacu- um, on the level of the sea, the yard being in the proportion of o6 inches to 39.1393 inches of the pendulum." This was the first attempt to refer the English foot to a natural standard. Ten years afterward, or in 183-4, the contingency provided for by this sta- tute actually occurred by the burning of the Houses of Parliament ; in which conflagration the celebrated brass standard of Bird was destroyed. Although the only actual legal standard was thus lost, no attempt was made to restore it by the pendulum, as provided by law ; but the mean of several different standards, including one belonging to the Royal Astronomical Society (for- tunately the Astronomical Society had procured a most carefully prepared copy of the imperial standard yard, and the Mint was in possession of an exact copy of the pound), was selected as giving the nearest approximation to the legal standard yard. A commission was appointed by the British Government, in 1888, " to con- sider the steps to be taken for the restoration of the Standards of Weight and Measure." The commissioners in their report, made in 1841, say : "We are of opinion that the definition contained in the Act 5, Geo. IV, c. 74, ss. 1 and 4, by which the standard yard and pound are declared to be respectively, a certain brass rod and a certain brass weight therein specified, is the best which it is possible to adopt. Since the passing of the said act, it has been ascertained that several elements of reduction of the pendulum experiments therein referred to are doubtful or erroneous; thus the reduction for the weight of air was erroneous ; the specific gravity of the pendulum was erroneously stated, the faults of the agate plates introduced some degree of doubt, and sensible errors were introduced in the operation of comparing the length of the pendulum with Shuckburgh's scale, used as the representative of the legal standard. It is evident, therefore, that the course prescribed by the act would not necessarily reproduce the length of the original yard. Several measures however exist, which were most accurately compared with the former standard yard. And we are fully persuaded that, with reasonable precautions, it will always be possible to provide for the accurate restoration by means of material copies which have been carefully compared with thorn, more surely than by reference to any experiments referring to natural con- stants." And the report concludes by recommending " that the standard of length be denned by the whole length of a certain piece of metal or other durable substance, supported in a certain manner, at a certain temperature ; or by the.distance between two points or lines engraved upon the surface of a certain piece of metal or other durable substance, supi)orted in a certain Taylor.] 6b4: [Oct. 21, manner and at a certain temperature ; but that the standard be in no way defined by reference to any natural basis, such as the length of the pendu- lum vibratirxg seconds in a specified place. •■■ * * That the standard of weiglit be defined by a certain piece of metal or other durable sub- stance," etc. It thus appears as the result of this last commission in England, that the people of that country are disposed to abandon all attempts at obtaining a natural standard, and to recur to the authority of an arbitrary rod or piece of metal, whose length has been derived from prescriptive custom. It should be considered, however, that after a natural standard has been obtained, we still have all the means of its material perpetuation, suggested in the com- missioners' report. And no foreign community is ever likely to accept as an authoritative unit of measure, a certain brass rod manufactured in England, and incapable of any more precise definition. Mr. Baily was selected to prepare the new standard, having five copies of the preceding on which to base his comparison ; on liis death, in 1844, Mr. Sheepshanks continued the necessary observations. Of several standard copies finally prepared by him, each being a square inch bar, of a bronze consisting of copper with a small percentage of tin and zinc, 38 inches in length, with half inch wells sunk to the middle of tlie bar, one inch from •eacli end, in which the lines defining the yard are drawn on gold plugs — six were finally selected and reported by the commissioners in March, 1854. Of these, the one marked " Bronze 19 "^was selected as the parliamentary standard yard, the remaining five" being deposited, along with copies of the standard of weight, with as many public institutions and scientific bodies. These stand- ards were legalized in July, 1855; and in case of loss of the parliamentary €opy, it was provided that the standard should be restored by comparison of the other selected copies, or such as might be available. Bronze bar No. 11 which has the standard length at a temperature of 61.79° has been presented to the United States, and is the actual standard of com- l^arison. In addition to the difficulties of obtaining from the pendulum the recon- struction of a lost standard, as above indicated, it is not unimportant to note that tliere is an original uncertainty in the determination of its length, of nearly the thousandth part of an inch. " We cannot venture to say that the clock's rate in a given day, can be determined certainly to within one-tenth part of a second, although the comparisons have been made at an interval of 24 hours. Seeing then that the free pendulum is compared with the clock only over a small fraction of the day, it is a great deal to expect that its daily rate can be ascertained to within one second of time. A change of one second per day in the I'ate of a clock, corresponds to a change of ^j^q, in the length o| the pendulum, which is about ^J^ ^ of an inch, or Jg- of a millimetre; and therefore we may regard this distance as indicating the probable limit of exactitude" {Encyclopedia Britannica, 8th edition, Vol. xvii, page 384, article "Pendulum," by Edward Sang). Note D. The only account we have been able to obtain of the important movement of Charles XII toward superseding tlie decimal by the octonary system, throughout Sweden, is that contained in a volume entitled " A Compendium 1887.] 'J^^ [Taylor. of the Theological and Spiritual Writings of Emanuel Swerteuborg " (royal octavo), published at Boston by Crosby & Xichols, 1854. In the life of Swe- denborg, prefixed to the "Compendium," it is said: "In 1719 he published four works ; first, 'A Proposal for Ji. ring the value of Coins and determining the Measures of Sweden, so as to suppress fractions, and facilitate Calcula- tions.' After which he was commanded by his Sovereign to draw up an Octonary Computus (a mode of computing by eighths), wliich he completed in a few days, with its application to the received divisions of Coins, Weights, and Measures ; a disquisition on Cubes and Squares, and a new and easy way of extracting Eoots; all illu.strated by appropriate examples " (Life, p. 'J). As Swedenborg devised for his " Octonary Computus," both a set of charac- ters and of new names, we were exceedingly anxious to have enriched this Paper with tlieir representation. We have tailed, however, to find any clue to these early publications in any of the public libraries or private collections to wliich we have had access. The only additional reference to the subject in the volume above referred to, is contained in a letter from Swedenborg to M. Xordberg, written after the death of Charles XII, wliich appears to detail the monarch's first conception of the project of a reformation in the popular system of numeration. An extract giving all that relates to the subject of octonary computation, is here copied : Letter of J/. Swedenhorg, Assessor of the Board of Mines, to M. JSfordherg, AutJior of the History of Charles XII. "Sir: — As you are now actually engaged upon tiie Life of Charles XII, I avail myself of the opportunity to give you some information concerning that monarch, which is perhaps new to you, and worthy of being transmitted to posterity. * Conversing one day with the King upon arithmetic, and the mode of counting, we observed that almost all nations, upon reaching ten, began again ; that those figures which occupy the first place, never change their value, while those in the second place were multiplied ten-fold, and so on with the others; to which we added that men had apparently begun by counting their fingers, and that this method was still practised by the people ; that arithmetic having been formed into a science, figures had been invented which were of the utmost service ; and, nevertheless, that the ancient mode of counting had been always retained, in beginning again after arriving at ten, and which is observed by putting each figure in its proper place. The King was of opinion that had such not been the origin of our mode of counting, a much better and more geometrical method might have been in- vented, and one which would have been of great utility in calculations, by making choice of some other periodical number than 10. That the number 10 had this great and necessary inconvenience, that wiien divided by 2, it could not be reduced to the number 1, without entering into fractions. Be- sides, as it comprehends neither the square, nor the cube, nor the fourth power of any number, many difficulties arise in numerical calculations. Whereas, had the periodical number been 8, or 16, a great facility would have resulted, the first being a cube number of which the root is 2, and the second a square number of which the root is 4 ; and that these numbers being divided by 2, their primitive, the number 1 would be obtained, which would be highly Brinton. ^"^ [Nov. 4, useful with regard to money and measures, by avoiding a quantity of frac- tions. Tlie King, after spealcing at great lengtli on tliis subject, expressed a desire tliat we sbould mal^e a trial with some other number than 10. Having represented to him that this could not be done unless we inventednew figures, to which also names altogether different from the ancient ones must be given, as otherwise great confusion would arise, he desired us to prepare an example in point. We chose the number 8, of which the cube root is 2, and wliich being divided by 2, is reduced to the primitive number 1. We also invented new figures, to which we gave new names, and proceeded according to the ordinary method ; after which we applied them to the cubic calculations, as well as to money, and to measures. The essay having been presented to the King, he was pleased with it" [Appendix to Life, etc., pp. 123, 124) . On the so-called Alaguilac Language of Guatemala. By D. G. Brinton, 3I.D. {Bead before the American Philosophical Socieli/, Nov. 4, 1887.) In his valuable treatise on the ethnography of the Republic Ouatemahi , Dr. Ofcto Stoll classes the Alaguilac language, once spoken by a tribe resident on the Motagua river in that country, among the languages of unknown affinities, Sprachen unbekann- ter Stellung ; and he also adds, that at the time of his visit to the vicinity — now about Sve years ago — the tongue was entirely €xtinct, being supplanted by the Spanish.* It were greatly to be regretted that any language or dialect should perish completely, leaving no record behind it b}^ which we can assign its place in the linguistic scheme. I am happy to say, this is not the case with the Alaguilac. I have in my hands materials from several sources from which to identify this now extinct tongue, and also to cast some interesting glimpses on the ancient civilization of the tribe w^hich once spoke it. These sources are : — I. Four leaves in folio, originals, from the archives of the Parish of San Cristobal Acasaguastlan, dating from 1610 to 1637, in bad condition, but mostly legible. II.

Several infornies of Don Eligio Pais, municipal judge of Chiquimula, and of the cura or parish priest of San Cristobal Acasaguastlan, Don Jose Inocente Cordon, dated in 18T8. With these means I am enabled to throw sufhcient light on the affinities of the Alaguilac language, and add something to our knowledge of the archaeology of the locality. First, a few words on its geographical location. The parish of San Cristobal Acasaguastlan is situate on the Motagua river in Guatemala, department of Chiquimula, fort}'- five miles northwest of the citj- of Guatemala. Its dependen- cies are the hamlets of Chimalapan, Usumatlan and Tecolutan. About eight miles to the east of it, is the parish of San Augus- tin Acasaguastlan, wdiose inhabitants formerl}' spoke the same tongue. In the letter descriptive of this region sent to the Kiiig of Spain, in 15lG,bythe Licentiate Diego Garcio de Palacio, he says briefly, " in the valle}' of Acacevastlan is spoken the Tlaca- cebastleca."* In the list of languages current in Guatemala as given by the historian Juarros, at the beginning of this century, no such tongue is mentioned, but in place of it, apparently, he names the Alaguilac.f The ordinary native tongue of that part of the vallej^ is the Chorti, a dialect of the Ma^^a of clear affinities, and all the surrounding tribes belong to the Maya stock. At present, as we have seen, travelers agree in the statement that all the Indians of Acasaguastlan speak Spani^:.h only, and the Alaguilac is reckoned therefore among the extinct tongues of America. The place-names mentioned in these accounts are clearly of Nahuatl origin. Acasaguastlan| is a slight modification of acaga- * Carta de Garcia Diego de Palacio, p. 20. Ed. Squier. t Ilidoria de Guatemala, Tom. ii, p. 35. I The term given by Palacio— Tlacacebastleea— is a derivative under the ordinarj' rules of Nahuatl grammar from Acaoacatlan, the termination era being the plural of the suffix genlilis, ecatl, and the preJix tla, meaning here the thing possessed by or i)eculiar to these people. Brinton ] "^" [Nov. 4, callan the place of rushes or reeds ; Chimalapan is compounded of c7izmaZ/z, a shield, with the post-position |:)an, in or at ; Usuma- tlan means the place of monkeys, from ozumatl, monkey, and tlcm, locative ending; and Tecolotan, the place of owls, from tecolotl, owl, and tlan. The word Alaguilac is stated in the MSS. before me to be tlie Mexican name of a species of edible fruit ; thougli were it not for this autliority, one might suppose it to be from the nomen gentile^ atlacuilecatl, which means " the people who live at the place of drawing water " {all, water, c»i, to take, ecatl, terminalio gentilis). Evidently, therefore, we find ourselves in a Nahuatl colony, one of those which were scattered through Central America, like tiie Pipiles of Escuintla, and the Nicaraos in Nicaragua. It has been shown recently that this active race extended its settlements almost to the isthmus of Panama, and established a colony on the borders of the Chiriqui Lagoon.* Everywhere they carried with them remini^cences of that advanced culture which thej^ had developed in the Valley of Mexico. Tills is manifest to-day by the superior make of pot- tery and the fragments of stone and brick edifices which mark the site of their ancient abodes. Acasaguastlan is no exception to this rule. In the informe of the worthy cui'a above mentioned, he writes as follows: — " At the confluence of the Rio Grande de Acasaguastlan [?. e., the Motagua river] with that of Teculutan, which is to the east of this parish, there are some prominent and remarkable relics of a dense native population, which prove this to have been the capital of a province. There are neat, level pavements which lead from the buildings to the river. The buildings themselves indicate that they were towers or pyramids. The base is circular and they must have had an altitude of fifty Spanish yards (varas). At present they are covered with lofty trees, and the ruin on the promontory, now the highest, is sixteen or twenty 3'ards in height. In the midst of these edifices, at the place named, there is a large open space, circular in form, like a plaza. A continu- ous row of mounds extends from these edifices and pyramids, on both sides of the main river, to the village of Acasaguastlan. * A. Pinart, in the Bcvue d'Ethnogmphie, Tome vi, p. 121, identifies tlie Seguas Indians of the Chiriqui Lagoon with the Nahuas. 1887.] «^0y [Brinton. One of these has been demolished, and proved to be of stone, yielding as much as two hundred perches, without counting the cement. Each of them contains an arch either complete or in ruins. In the one mentioned, three small arches were found, constructed with some symmetry, but it was not ascertained whether the material was joined by lime, as at present it looks more like cla3^ Portions of the wall were smoothly plastered and some nearly erased paintings were visible. In the structure were found earthen pots, some roughly made, others of excellent workmanship, and with them incense burners, such as the Indians use at the j^resent day in their Brotherhoods (cofradias). There were also found pieces of brick, much like foreign brick, meal- stones in the shape of large shells, arrow points of glass [i. e., volcanic glass, obsidian], and human bones. No one has taken special interest in investigating these remains, and I have known persons who seemed quite intelligent pass by them without awarding them the least attention, and as if they did not see them. Finallj^, I add that I am assured that no precious metal has been discovered in them, although they may have had anti- mony, which the Indians used to polish their earthenware as it is quite lustrous." Such is the interesting description furnished by the parish priest, and it reveals plainly that the ancient race of Acasaguas- tlan belonged among the more highly cultivated nations of the continent. I have not found in the historians of Guatemala the records of the first exploration of this portion of the valley of the Mota- gua, nor in later travelers the account of any visit to these ruins. It would be of especial interest to determine whether they ap- proach the distinctively Mexican or the Maji'a style of architec- ture. The presence of the arch points to the latter, but this architectural element was not altogether foreign to the former. Fifty miles as the bird flies, lower down the Motagua river, are located the remarkable ruins of Quirigua, with their elabo- rately carven monoliths, twenty feet or more in height. Accord- ing to the most recent observers,* these relics present evidences of an antiquity greatly exceeding that of Copan or Palenque, both which venerable sites had long been deserted at the period * See Copan unci Quirigua, by Heinrich Meye and Dr. Julius Schmidt, Berlin, 1883.

The valle}^ of the river Motagua, therefore, was probably one of the centres of Central American civiliza- tion, and a study of its archaeology might prove peculiarly pro- ductive. The reduction and conversion of the tribe dwelling at Acasa- guastlan probably took place before the middle of the sixteenth century. The intelligent members of the community were taught to read and write their native tongue, and the records in my hands are by native scribes, wlio kept these notes or accounts in order to submit them from time to time to their civil or ecclesi- astical superiors. These records are in a dialect of Nahuatl closely akin to that of the Pipiles of Escuintla and the neighborhood. Both dialects are but slight modifications of the tongue as spoken in its purity in the Valley of Mexico. Perhaps much of the apparent differ- ence is due to an uncertain orthography and the inexpertness of the writers. The subjoined extracts from the archives under the dates 1610, 1634, 1636 and 1637, will show conclusively that the Na- huatl was the current tongue of the parish at that time. The entries relate to fines which were imposed on the natives for various misdemeanors, and of which the civil officers were obliged to pay a portion from time to time to their superiors. The re- ceipts of these superiors are entered in Spanish in the archives and present the honored autographs of Juan de Montoya and G. de Mendieta. Although various Spanish words occur, and the imperfect handwriting as well as the poor condition of the MSS. render these specimens less satisfactory than could be wished, it will nevertheless be apparent at a glance that the dialect is a toler- abl}^ pure Nahuatl, such as was common in Mexico a century after the Conquest.

The compari- son leaves no doubt whatever, that the Alaguilac was a quite pure form of the Nahuatl, and when we allow for the difference in the orthography of Bromowicz, who writes as a German, from that of Molina, the variation is surprisingly little. In the phrases the schi represents the usual Nahuatl imperative form xi, the X in that tongue having the sound of the German sch and the English sh in " she." The only cliange which has taken place in the numerals is in the number nine, the substitution for chicunaui^ " one hand and four fingers," of niatakticwmi ; but I have no doubt this was a piece of forgetfulness on the part of the venerable Dolores, and that she gave the word for twelve, matlactUome (10 + 2), instead of that for nine. Two questions will arise in the mind of the critical reader : 1. Did any other -language exist at Acasaguastlan to which the name Alaguilac could have been applied? If not, and allowing it to have been merely a slightly altered form of the Nahuatl, was it introduced into that locality before or after the Conquest ? To the first of these questions, we may safely reply with a clear negative. There is not a native proper name in the vicinity but belongs either to Nahuatl or Chorti. There is not the slightest 1887.] 377 [Cope_ evidence in the Nahuatl vocabulary of the influence of any ter- tiiim quid. We may positively exclude the supposition of a third, wholly lost and unknown tongue, and unhesitatingly identify the " Alaguilac " of Juarros, with the " Tlacabastleca " of Palacio, and both with the ordinary Nahuatl.* With this identification the last remaining problem in the aboriginal linguistics of Guatemala is solved. We may now confidentlj' say that there was not a tribe found anywhere on its surface by the first explorers of whose linguistic affiliations we are ignorant. Every one can be assigned to its proper ethno- graphic group so far as this is practicable by a knowledge of its dialect. As to the second query, whether this Nahuatl colony immi- grated before or after the Conquest, we are without positive evidence. But the letter of Palacio, written in 1576, from observations extending over years previous to that date, indicates distinctly that the language of Acasaguastlan had a recognized and independent existence in his day, and, therefore, that the people who spoke it had been found in place when the Spaniards first mapped out the land. This colony of Nahuas, which had wandered into the upper valley of the Motagua river, was probably an off-shoot from the extensive settlements which their kindred possessed on the Pa- cific slope in the present Department of Escuintla, some eighty or ninety English miles distant.

The latter names are very expressive of the dental characteristics of the two groups (tubercle and crescent bearing), but not having priority, they have come into use as the adjectives buno- dont and selenodont, to describe the types of molar crowns to which they refer. But the divisions themselves can no longer be maintained, in view of the numerous extinct forms now known to connect them. Not only do transitions occur, but they occur at different points. Thus Dichobune is the bunodout which corresponds with the selenodont Csenotherium ; and Chojropotamus corresponds in the same way with Hyopotamus, An- thracotherium standing between. If it be desirable to name the natural groups into which the families fall, names enough exist in works on the subject, but the divisions they have been applied to are not exactly in accordance with the present writer's views of their true relations. These are presented in the following table. In this work I have been much aided by the Papers of Turner and Flower, which appeared in the Pro- ceedings of the Zoological Society, of London, for 1850 and 1875 ; and of Gill in Smithsonian Miscell.

Statements as to the phylogeny of a given group, as family, or genus, are intended to apply to them as defined in the present paper in the tables ; in other words, the phylogenies represent the history of particular structures. There is a tendency among writers, even with some of the best, in considering questions of phylogeny, to restrict their attention to some particular species of a genus, or genus of a family, and to consider all the minor peculiarities of said species or genus, whether appropriate to the wider question before them or not. In brief, I have not attempted to present any phylogeny of species. It will be long before we have the necessary material for that. I. Superior molars tritubercular (Pantolestoidea).

But few of them in fact (some Cienolheriidae and Anthracotheriidic) survived the Eocene epoch. Division III is, on the other hand, characteristic of Mio- cene and recent time, except that some specimens of Gelocus of the Tragu- lidse have been found in Upper Eocene beds. Several genera of Tragulidoe, * Antilocapra is sometimes separated from the Bovida; as the type of a family, because it is said t« sometimes shed its horny horn-sheath. This character, were it really nor- mal, has no significance sufficient for the establishment of a family division. Cope.] ^"0 [Oct. 7, with Elotheriiim and Poebrotherium and Oreodon, belong to Oligocene beds. Tubercular or bunodont molars are of prior age to selenodont molars, phylogenetically speaking. Of the former, the tritubercular type, it has already been shown, is ancestral to the quadritubercular type. Panto- lestidse are then clearly ancestral to all known Artiodactyla, and are themselves probably the descendants of the lost Amblypoda Hyodonta, whose existence I have anticipated on hypothetical grounds. Of the remaining families which are constructed on the quadritubercular basis, there are two types, as represented in divisions II and III of the pre- ceding table. The intermediate or fifth lobe is especially characteristic of Eocene Artiodactyla. The intermediate tubercles exist in the Pan- tolestidaj, and one of them is preserved in the families of division II ; but in group A it is the posterior one, and in group A A it is the anterior one. In the Suidse and Elotheriidae, which are permanently bunodont, the intermediates are either lost or so divided as to lose their distinctive character. In Elotherium traces of both the interme- diates are visible, but they are obscure. The genetic relations of the families with five lobes to those with four are supposed by Schlosser to be direct and ancestral. This looks probable in the case of the Merycopo- tamida: of the latter group, which has inferior molars like those of Hyopota- mus of the former group. Whether the remaining families of division III AAA (see table) (four-lobed) came off from the families of division II (five-lobed) is uncertain. It is probable that the fifth and si::th (or inter- mediate) tubercles were present in all primitive Artiodactyla, but they may have been lost, as in the Suida3, in the bunodont stage, wliich gave origin to III AAA, so as to be wanting from the earliest four lobed seleno- dont ancestors. Of the two types of II, the division A (Dichobunoidea) is supposed by Schlosser to have been the ancestor of the true selenodonts (III AAA), but excepting in the case of Merycopotamidge this has not yet been demonstrated. Scott suspects with reason that the quinquetubercu- lar Protoreodon is the ancestor of the quadritubercular Oreodon. Leaving this debatable question, I refer to the family of the Anoplo- theriidae. The remarkable structure of the feet discovered by Gervais, and shown by Schlosser to belong to this family, distinguishes it at once from all families of this and all other orders. The second digit is well developed in both feet, and stands inwards at a strong angle to the other toes. A rudimental fifth is present in the manus, but not in the pes. The latter is therefore tridactyle. The third and fourth digits are equal in the pes, but the third exceeds the fourth in the manus, giving an entirely perissodactyle character. Some didactyle forms have been placed in this family, but this is inadmis- sible on ordinary taxonomic principles. The divergent inner toe is sup- posed to have supported a web, useful in an aquatic life. As remarked by Schlosser, the origin of the Anoplotheridse is entirely obscure as yet, the only ancestor yet known being the Pantolestidae. It is probable that some 1887.] *^"-^ [Cope. unknown member of the Antliracotheroidea, which had bunodont teeth, may form one of the missing links. Cebochoerus offers the proper type of dentition, and the number of toes (four, Schlosser) is also appropriate, but whether there are any structural obstacles to its being ancestral to the Anoplotheriidse I do not know. Anthracotheriid?e can be properly supposed to have descended from a type of Pantolestidge with well-developed lateral toes, by the addition of the fourth tubercle, and the loss of the posterior intermediate ; while the Dichobunidte have had the same origin, the posterior intermediate cusp being preserved. The Xiphodontidse may be supposed to have come oflE from the Anthracotheriida3 by the usual process of diminishing the lateral digits and developing both sets of crescents in both superior and inferior molars. This family carried the specialization of the five tubercled type farther than any other. The Suoidea have come off from the Pantolestoidea by the addition of the fourth (posterior internal) tubercle to the superior molars. Some genus with better developed lateral (second and fifth) digits than Panto- lestes must have been the ancestor. Such a form will be discovered. It has been already anticipated by Schlosser.* It is evident that the Listriodontidae form a special short side branch, with a type of molar teeth, especially in the lower series, resembling some of the Perissodactyla. The nearest approach to it is seen in the genus Platygonus of the Suidoe, which has more complex premolars. Here the four cusps of the quadritubercular bunodont type are fused together into transverse crests. The limbs of Listriodon are unknown. It is a circumstpnce confirmatory of the view that the Cameloidea and Booidea are descendants of the Anthracotheroidea rather than of the Suo- idea, that no genus of the latter superfamily shows the least tendency to assume a selenodont structure of the molars. It is therefore not unlikely that the two groups named may have had the history of the Merycopo- tamoidea already referred to. They did not probably come from the Mery- copotamoidea themselves, since the geological age of the latter is too late. Of course, however, members of this group may be yet discovered in earlier formations. The problems of the phylogeny of the remaining groups are less diffi- cult, and have been largely solved by the investigations of Kowalevsky and Schlosser. Tragulidae have been derived from OreodontidiB with simpler premolar teeth than the typical forms, [e. g. Dorcatherium and Lophiomeryx). In turn they have given origin to primitive Bovidaa (Cosoryx) through Gelocus, which have then branched off" into specialized Bovidse on the one hand, and Cervidoe on the other. The Poebrotheriidse have originated from some family with diminished lateral digits, perhaps the Dichobunidse, various intermediate genera being yet unknown. They * Jlorphologisches Jahrliucli, 188G, p. 77, Cope.] 382 [Oct. 7, are ihe direct ancestors of the Protolabidid;^, the camels, and the Escha- tiidae. These relations may be expressed in the following table : H Ph 8 •^ s o 3 TS tsD o Of Pantolestid^ but one genus is known. The premolars are all simple in the upper jaw, except the fourth, which has one external and one internal tubercle. The structure of the premolars in Anoplotherium is complex for so primitive a type, and the third superior has an internal crest as well devel- oped as in some of the Booidea. To the Anoplotheriid^ are referred, besides Anoplotherium, Diplobune of Fraas and Dacrytherium, Mixto- 1887.] ^^^ [Cope. theriuin and Mixochcerus of Filhol. But the structure of the feet of the latter geuera is unknown. In Mixtotherium the fourth premolar is more, and the others less complex than in Anoplotherium. The known genera of Dichobunid.e are Dichobune of Cuvler, with Spaniotherium and Dilotherium of Filhol, in which the. intermediate tu- bercles are less developed than in Dichobune. They are related to the two selenodont genera of C^notheriid^, Ca^notherium and Muillacthe- rium. Tlie latter differs from the former in the absence of the intermediate crescent from the last superior molars. The species of Ca?notherium differ in the absence or presence of a short diastema in the dental series, and in its position in the lower jaw, whether behind the first or second premolar. The Dichobunid bunodout geuera are ancestral to the Ca3notheriid sele- nodont genera in the following fashion : Cajnotherium Muillactherium Spaniotherium Dilotherium Dichobune This family terminated with the selenodont genera, which, as Schlosser remarks, left no known descendants. The ANTHRACOTHEniiD^ present but few variations. Four genera are known, which differ as follows : Entirely bunodont ; no diastemata ; canines developed. Geboch(Krus Gerv, Cusps of superior molars little flattened ; diastemata ; canines large Choiropotamus Cuv. Cusps of superior molars flattened ; no diastemata ; canines large Anthracotherium Cuv. Cusps of superior molars crescentoid in section ; diastemata ; canines large in males Hyopotamus Owen. The three genera last named cannot, as Schlosser remarks, be related in direct lines, but through cbmmon ancestors ; as may be shown thus : Hyopotamus Anthracotherium Choeropotamus Cebochcerus Cope.] 384 [Oct. 7, The ancestral geuus is bunodont, without diastemata, and with well- developed canines. The hypothetical genus (1) is selenodont, with short diastema, and well-developed canines.

The relations of these genera are clearly somewhat like those of the preceding family. The bunodont condition of the molars of Rhagathe- rium is primitive, while its diastemata are the reverse. The continuous dental series of Xiphodon is primitive, while the detailed structure of the molars is advanced. These relations may be thus shown : • Xiphodontotherium Protoreodon y Xiphodon Rhagatherium The hypothetical genus 1 is simply a bunodont without diastemata, and with well-developed canines. The pigs, SuiD^, are an old family, although no genus is known prior to Miocene time. The genera present considerable variety among them- selves, but some of the existing genera differ very little from some of the earliest. The greatest diversity is seen in the modifications of the incisor and canine teeth. ■ The following represents the characters : I. Metapodials fused proximally (Dicotylinte). a.

The absence of intermediate types renders the determination of the phylogeny of the genera as yet impracticable. The main features may however be foreshadowed. The most generalized form is Thinohyus, since its dentition is in all respects the most simple, while it preserves the full number of teeth. It may readily have given origin to the Dicotyline line on the one side, and Sus and its immediate allies on the other. Babi- russa is another derivative from the same center. Phacochcerus may have come from some ally of Sus, since it carries to a great extreme the pecu- liarities of the latter genus. The ancestry of Hippopotamus is less easily determined. Its imperfect distal metapodial keels, which only exist on the posterior face of the condyle, bespeak for it an ancient ancestor. Its molar type is merely a complication of the quadritubercular, while the characters of its canines are an exaggeration of those of the primitive forms already mentioned. Several other genera, as Dicotyles and Sus, display the decumbent incisors which prepare the way for the remarkable straight digging incisors of Hippopotamus. The genus Chceropsis eases the passage backwards. These relations may be expressed as follows : Chceropsis Phacochcerus Platygonus Hippopotamus I Hexaprotodon Dicotyles Babirussa Sus Chaenohyus Thinohyus PKOC. AMER. PIIILOS. SOC. XXIV. 12(3. 2w. PRINTED DEC. 3, 1887. Cope.] ^ob [Oct. 7, But one genus of Elotheriid^ is known. The character of the feet, reduced to but two metapodials in a bunodont genus of the Lower Mio- cene or Oligocene, surprised Kowalevsky, wlio first determined the fact, and has excited simihir feelings in otlier naturalists. But the precocious diminution of the lateral digits has been already observed in various primitive genera, as Pantolestes and Dichobune, and from one or perhaps both of these forms Elotherium was derived. In its dental characters it is of the simple suilline type. The type early ceased to exist, its latest forms being American, and some of them rivaled the rhinoceroses in dimensions. The Ltstriodontid^e and Merycopotamid^ include but one genus each, though others probably will be discovered. I therefore turn to the Oreodontid^ which embraces a larger number of forms. Its characters are as follows : Dentition : superior incisors present ; molars selenodont. Cervicals with the transverse processes perforated by the vertebrarterial canal. No alisphenoid canal. Ulna and radius, and tibia and fibula distinct. Meta- podial bones four on each foot, with incomplete distal trochlear keels. Lunar bone not supported by magnum. Navicular and cuboid bones dis- tinct. The details of the structure express various affinities. The axis is intermediate between that of the suilline and ruminant Artiodactyla ; the otlier cervicals are suilline, while the remaining vertebrae are ruminant. The scapula is ruminant, not suilline ; while the humerus is like Anoplo- therium. The radiocarpal articulation is intermediate between that of hogs and ruminants. The unciform supports the lunar bone. The sacrum is ruminant, the ilium suilline. The femur and tarsus are much like those of the peccary. The known genera of this family are the following : A. Orbit complete ; premolars four, the fourth with one external crescent. First premolar below functioning as canine. a. No facial vacuities. Premaxillaries distinct ; otic bullae not inflated ; five digits in manus Oreodon Leidy. Premaxillaries distinct ; otic bullse inflated ; four digits in manus Eucrotaplais Leidy. Premaxillaries coossified ; otic bullae inflated Merycochosrvs Leidy. aa. Facial vacuities present. Premaxillaries coossified, dentigerous ; vacuities prelachrymal only Merychyus Leidy. Incisors six above, persistent ; vacuities prelachrymal and prefrontal ; nasal bones much reduced LeptaucJienia Leidy. Incisors very few, caducous ; vacuities very large Cyclopidius Cope. A A. Inferior premolars three. True inferior canine functional. Inferior incisors one on each side Pitliecistes Cope. 1887.] 387 [Cope. Starting from Oreodon as the ancestral form, Eucrotaphus follows at a little distance. The presence of the pollex observed by Scott in Oreodon proves that it must be referred to a five-toed common ancestor with Dor- catherium. The enlarged bulla? are added in Eucrotaphus, and the coos- sified premaxillaries in Merycochcerus and Merychyus. The latter com- mences the facial vacuities, which reach such huge proportions in Leptauchenia and Cyclopidius. The loss of the incisor teeth from both jaws, and diminished size, indicate that decadence is going on in Cyclo- pidius, but the last term is reached in Pithecistes. Here not only incisors but a premolar disappears. This family, once powerful in numbers, size and strength, disappeared with the Upper Miocene period in North Amer- ica. These relations may be thus displayed. A common ancestor with Dorcatherium is assumed. This will be a genus like Protoreodon S. &0., but without the caniniform inferior p. m. i of that genus, and probably with the fifth crescent of the superior molars. Agriochcerus may have been derived from the same, Pithecistes Coloreodon 1 Agriochcerus Dichodon \ Cyclopidius I Leptauchenia i Merychyus 1 Merycochcierus I Eucrotaphus I Oreodon (Tragulidae) Dorcatherium Cope.] 388 [Oct. 7, The geological positions of these genera are as follows : Oreodontince.

These resemble, according to Schlosser,*the milk teeth of other ruminants in the genus Dichodon. For the present I associate with this European genus, the American Agriochoerus and Coloreodon, in which the last lower pre- molar resembles a true molar, and the last upper has two external Vs as in a true molar. The structure of the feet in these genera is unknown, but in Dichodon they are supposed to consist of the two median digits only, which do not form a cannon bone.f It is safe to conclude that the American forms do not possess a cannon bone, and as the presence or absence of lateral digits is not always a family character, I leave them provisionally in the DichodontidtB to which they are in any case nearly allied. They agree also in the resemblance of the inferior canine to an incisor tooth, but the first premolar is caniniform in the American genera, which it is not in Dichodon. The genera differ as follows : I. First inferior premolar caniniform. Premolars three Coloreodon Cope. Premolars four Agriochcerus Leidy. IL First inferior premolar not caniniform. Premolars four Dichodon Owen. In this instance the genus of more modern type, Dichodon, is the oldest in time (Upper Eocene), the other genera being Lower Miocene. These types have been derived from some common ancestor of the family of Oreodontidie as here defined. Dichodon may be a descendant of Lophi- omeryx, and Agriochoerus be derived from an ancestor in common with that genus and Dorcatherium (for diagram see under Oreodontidiie). The Tragulidje has a good many extinct genera, and the genus Tragu- lus is represented by several living species. It is difficult to separate this family from the Oreodoutidte, and the only character which appears to be * Beitriige z. Kenntniss d. Stammesgeschichte d. Hufthiere u.

If this character be not used, then the two families will form a sin- gle natural division. This definition includes in the Tragulida^ the Gelo- cidfo of Schlosser, a result inevitable on any exact system. The genera remaining, of which the limb structure is known, are defined as below. Several other genera are known from teeth, as Micromeryx, Phanero- meryx, Rutitherium, etc., but since their feet are not described, I am com- pelled to omit them. I.

Of these genera, those with the metatarsals separate, and the simplest premolar teeth, must be the most primitive and nearest the Oreodontida^. Dorcatherium, also an existing genus, has four well-developed digits, and is nearest the Oreodontida3. The only difference between that family and the present one being the presence and absence of the naviculo- cuboid bone respectively, Dorcatherium must be placed on the Trag- ulid side of the line. Probably extinct genera will be found which will connect this genus more intimately with the Oreodontida?, for the slight complication of the premolars of the extinct genera of the lat- ter, testify to earlier members with simpler ones. Lophiomeryx and Cope.] *>"^ [Oct. 7, Hyperlragulus must be associated with Dorcatlierium on account of the lack of cannon bone. Lophiomeryx has an inferior type of inferior true molar, and like Dorcatlierium has four toes on all the feet. Hyper- lragulus displays greater specialization in the absence of lateral digits from the posterior feet. The ulna is also coossified with the radius, and there is a naviculocuboid bone. The premolar teeth are nevertheless very sim- ple, and are separated by diastemata in both jaws. It must be regarded as a modified descendant of Dorcatlierium on one side of the main line of descent. In the next group the metatarsals have united while the metacarpals re- main separate. This is the case in Leptomeryx of the American Oligo- cene. In Tragulus the premolars are much simpler than those of the other genera of Section III, and simpler than those of Leptomeryx, so that these two forms must have been derived from an ancestor which combined the simplicity of both forms. For this we must again recur to Dorcathe. rium, and I therefore insert this genus at the base of the following dia- gram. With its entirely prismatic molars Hypisodus has one element of superiority, but the number of its superior premolars is unknown. Prodremotherium Bachitherium y Amphitragulus Gelocus \ \ Tragulus Leptomeryx / Hypertragulus Dorcatherium I Lophiomeryx Of the PoEBROTHERiiD^ there are two genera. These differ as fol- lows : First premolar of upper jaw elongate and with two roots Poebr other ium Leidy. First upper premolar short and with a simple conic root GompJiotJierium Cope. The phylogenetic relations of these genera correspond with their rela- tive geological positions. In Gomphotherium from the John Day (Mid- dle) Miocene, the first premolar is much reduced, probably soon to be aborted, as is the case in later genera of the line, among the Camelidte. In Poebrotherium it displays an unusual development, like that of some Tragulida3. With the Poebrotheriidse we commence a series of families characterized by the absence of the vertebrarterial canal, or the line of the camels proper. 1887.] ^♦^J- [Cope The direct connection with the f^imilies previously described is not yet known. The indications point to the Oreodontidfc, but no approach to the cervical vertebrae of the Poebrotheriidi3e has yet been found in that family. Messrs. Scott and Osborn have described a mammal, from the Bridger Eocene of Wyoming, as a probable member of the camel series, under the name of Ithygrammodoti cameloides. It is only known from two pre- maxillary and a part of one maxillary bones. The former are slender and bear a complete set of incisor teeth, which ai'e followed by a large canine. It is probable that this genus belongs in the camel series, but it cannot yet be positively affirmed. Ancestral to the Camelida; is the genus Protolabis Cope, which agrees with Procamelus, the earliest genus of that family in most respects, but differs decidedly in having a full set of superior incisor teeth. In this genus we reach the stage, in tracing back the ancestry of the camels, which we find represented by Oreodon, or the Gelocus in the line of the cattle and deer. It is probable, though not certain, that in Protolabis the metapodial bones are combined into a cannon bone as in the Camelidae. If so it differs materially from its predecessor, the genus Pcebrotherium, and must be regarded as the type of a special family, the Protolabidi- D^. But one genus of this family is known up to the present time. Its remains occur in the Ticholeptus beds of Oregon and the Loup Fork beds of Nebraska and Kansas. In the Camelid^ we begin to realize the characters of the latest Artio- dactyla, the ruminants. But they diflfer from the typical forms of these, the Booidea, in three important points of the osteology, viz., in the absence of a canal of the cervical vertebrce which in other Mammalia en- closes the vertebral artery ; the presence of an incisor tooth on each side of the upper jaw ; and thirdly, the incompleteness of the keels of the dis- tal ends of the metapodial bones. This character and that of the presence of incisors, are primitive conditions common to all the early Mammalia. The peculiar cervical vertebrsE constitute a specialization, but whether degenerate or progressive remains to be ascertained. In one respect this line exhibits a high specialization, which is present at the earliest known period of its history. This consists in the reduction of the lateral (ii and v) metapodial bones, so that but two functional toes remain. This condi- tion has been reached by the more typical artiodactyles after a much longer lapse of time, for most of the extinct and recent types display lat- eral digits in a well-developed or rudimentary condition ; in but few of them have they totally disappeared. In another respect the line of the camels attains a higher specialization than that of the typical ruminants, although its beginning is that which is common to the entire suborder. This is in the dentition. The reduction in numbers of teeth shown by Owen to characterize the historical succession of all Mammalia, is carried further in the molar series of camels than in any hoofed order ;- for in the final term or genus, Eschatius (Cope), there is but one premolar left in the upper jaw, and that is reduced to a simple cone. The true molars never Cope.] 332 fQ(,t -_ reach the complexity of those of the other line, of the Bovida^ or oxen, nor do they become prismatic as iu that family, but retain the short crown well distinguished from long roots, which belongs to all the earlier Mam malia. The successional reduction in the numbers of premolar teeth in the family of the Camelid* is shown in the following table.* There is seen in the genera Protauchenia and Palauchenia a tendencj'' to an increase of complication of the fourth inferior premolar : I.

It may be remarked that the latter genus, which is confined to the new world, is more specialized than Camelus, which is restricted to the old world. The succession of these genera in connection with the two preceding families, may be presented as follows : No cannon bone. Cannon bone present. Incisor teeth present.

The embry- onic history of these parts is as follows : In the fcetal state all the Ru- miuantia (to which the camels belong) have the cannon bones divided as in Poebrotherium ; they exhibit also incisor teeth, as in that genus and Protolabis. Very young recent camels have the additional premolar of Pliauchenia. They shed this tooth at an early period, but very rarely a camel is found in which the tooth persists. The anterior premolar of the normal Camelus is in like manner found in the young llama (Auchenia), but is shed long before the animal attains maturity. I may add that in some species of Procamelus caducous scales of enamel and dentine in shallow cavities represent the incisor dentition of Protolabis. In greater detail, the extinct American forms of this line are distributed as follows : Eocene. Miocene. Pliocene. White John Ticholep- Loup Wasatch. Bridger River. Day. tus. Fork. Equus.

The development of the brain displays the same progress that has been shown by Lartet and Marsh to have taken place in other lines of Mam- malia. The figures which I have given of the brain, show that while Proca- melus occidentalis is inferior to the camel in the size and development of the convolutions of the hemispheres, it is in advance of the Poebrotherium vilsoni in these respects. The development of the camels in North America presents a remark- able parallel to that of the horses. The ancestors of both lines appear together in the Wasatch or lowest Eocene, and the successive forms de- velop side by side in all the succeeding formations. Camels and horses are standard types in all our Tertiary formations ; and they must be learned by any one who wishes to distinguish readily the horizons one from the other. The horse-forms are more numerous in all the beds, in individuals as well as in species. Both lines died out in North America, and of the two, the camels only have certainly held their own in South America. The history of the succession of horses in Europe, although not as complete as that in America, extends over as wide a period of time. PROC. AMER. PHILOS. SOC. XXIV. 126. 2x. PRINTED DEC. 3, 1887. Cope.] ^^^ [Oct. 7, Not so witli the camels. There is no evidence of the existence of the camel line in the old world prior to the late Miocene epoch ; and so far as the existing evidence goes, the new world furnished the camel to the old. CamelidiB only appear in South American palaeontology in the genus Auchenia, in Pliocene time, in the Pampean beds. The best known spe- cies are Auchenia weddellii and A. intermedia of Gervais. It is curious that M. Ameghino, in his report on the fauna of the Miocene age found on the River Parana, which contains the ancestors of so many Pliocene genera, finds none that stand in that relation to the llamas. The EsCHATiiD.'E includes a single genus represented by large species of North America and Mexico. We now reach the division of the Artiodactyla, which is especially characteristic of the present period ; the Booidea, or, as it is sometimes called, the Pecora. It embraces more numerous species than any existing division of the Ungulata, and presents considerable difficulties to the zoologist who would represent the relations of its contents. As a division it is however well defined by the following peculiarities. The third and generally the second superior premolar teeth possess an internal crest as well as the fourth. The inferior premolar teeth have oblique transverse crests. The keel of the distal extremity of the meta- podial bones extends to the front of the condyle. The lateral metapodials are represented by their extremities only, the middle portion having dis- appeared. The median pair are united into a cannon bone. There are no superior incisors, The odontoid process of the axis vertebra is trough- shaped. The stomach is divided into three or four parts. The lowest family of the series is that of the Moschid^. In its hard parts it differs from the other Bovidse in the simplicity of the anterior (second) superior premolar, which is without the internal crescent found in the other Booidea. In this respect it is intermediate between that divi- sion and the Cameloidea, where the fourth premolar only possesses the internal crescent. But two genera of Moschidoe are known, Dremothe- rium from the Lower Miocene of France, and the living Moschus. Both lack horns and have well-developed canine teeth. The origin of this group is clearly from the Tragulida^, and the genus of that family which approaches nearest to it is Amphitragulus, which indeed only difiers from it in dentition in the imperfection of the internal crest of the third superior premolar. In turn, Dremotherium must be regarded as ancestral to Palieomeryx, the most primitive genus of the Bovidoe. The GiRAFFiD^ differ (see table of families) in the mode of attachment of the horns. These are originally separate from the skull, but become attached to it like the epiphyses on the extremities of the bones of the skeleton. Their dental characters are like those of the Cervidse and the lower Bovidse, the molars being short crowned or brachyodont. It may be that the condition of the horns in Giraffa represents the mode of origin of the horns of the Bovidae, and that the genus is simply to be reckoned a primitive type in that family. The specialization of the long 1887.] ^*^^ [Cope. neck and fore legs would not exclude it from that family. It is merely an adaptation for the habit of browsing on the foliage of tall trees. In the extinct species of its single genus, GirafFa, these characters are found in a less degree than in the existing one. The most obvious distiucliou between the BoviD^ and the Cervidie is in the differing character of the bony pro cesses of the skull, used for ofiense and defense. But where horns are •wanting, as is the case with some genera, these distinctions fall to the ground. The horn-type of the Bovidte is more primitive than that of the Cervidaj, since the horny process is permanent in the former, and is shed and reproduced annually in the latter. The dental type is, however, never so specialized in the deer, as is the case with the nighcst genera of Bovidse, remaining always distinctly rooted, while in Bos and some other genera of the latter they become prismatic. But the lower genera of Bovidse do not differ from Cervidae in this respect. In accordance with these fixcts the bovine ruminants appear a little be- fore the cervine, though authors generally refer the earliest genera to the latter division. Such are the genera Dicrocerus and Cosoryx,* which appear in the latest Miocene beds. Dicrocerus only diflers from Palae- omeryx in the possession of horns, which resemble those of deer, but which were, according to Schlosser, never shed, a fact which compels its location in the Bovidie. In Cosoryx the horns have the same charac- ter in this respect, but the teeth are antelopine, or prismatic. It is clearly to be placed in the Bovidai with Antilocapra (the prong-horn), and it is closely allied to Dicrocerus. Here we see that the point of origin of the two families was from a common ancestor, and that this ancestor was, as has been -already expressed by Schlosser, the genus Pala^omeryx. Nearly related to this point of departure are the Sivatherium, Bramatlierium, and Hydaspidotherium. As they do not shed their horns, they cannot be re. ferred to the Cervidse. In their covering with the integument, Cosoryx probably possessed a character of Giraffa, which is a primitive stage of the essential character of the horns of the Bovidix;. Perhaps the retention of the primitive dermal character of this investment, instead of its metamor- phosis into horn, might be regarded as a basis for a distinct family, the CosorycidfB. But it is highly improbable that this covering remained in Sivatherium and Bramatherium, whose horns were apparently perfectly naked. It is doubtful whether all these animals can be retained as distinct from the Bovidaj, and I therefore place them in two subfamilies of that family. The Cosorycinaj, which will include Cosorj'x and Blastomeryx, are characterized by the sheath of the horns being dermal ; the Sivathe- riinne by the absence of any sheath whatever. The synopsis of genera will then be as follows : I. No horns in the male. Molars brachyodout Fakeomery.v\ Von Meyer. * Leidy, Cope ; Procervulus Gaiidry. t Should P. eminens, type of Palceomeryx, have possessed horns, as suspected by Schlosser, the generic name must take the place of Dicrocerus below, and be replaced by one of the various names which apply to hornless species.

So far as concerns the skeleton, further subdivisions than those indicated in the above table do not appear to exist, and none have been pointed out. The divisions proposed appear to be rather those of one extensive genus. The modifications of tlie skull have reference to the position of the horns. These are processes of the frontal bones, and are placed at points from above the eye to the posterior angle of the facial plane of the skull. In the latter case this angle approaches very near to the supraoccipital crest or inion, and the parietal bone is reduced to an exceedingly narrow band between the frontal and occipital bones (Riitimeyer).* Forms with anterior horns and well-developed parietal bone are Ocis gazella and Tetrarerus quadricornis , "while the Ocis gnu displays the parietal extremely reduced, and become chiefly lateral in position. As regards the forms of the horns themselves, they present no important differences, but are angular and revolute in the section Ovis, and cylindric in the division Antilope. In the latter they vary in direction from straight to spiral or curved in different directions. Within the genus Ovis the end of the muzzle is naked or hairy, the latter in the typical forms and in those inhabiting northern and alpine localities generally. Those species that inhabit grassy or desert plains have the end of the nose naked. Within the genus Bos modifications are observed parallel to those in the genus Ovis. The frontal bones with the horn processes are produced more and more posteriorly until the parietal bones are reduced to a narrow band across the posterior part of the skull. The bisons have the horns most anterior ; then follow the buffalos, and the extreme is reached in the true oxen, of which the domesticated animal is the type. The following'table will give an idea of the phylogeuy of the Bovidse : Ssega Bos Tetracerus Sivatheriinne CervMae Ovis Antilocapra Dicrocerus . Cosoryx Blastomeryx Palieomeryx The hornless Palteomeryx has given origin to the horned BoiJidea ; on the one hand to the brachyodont (Blastomeryx, etc.), and on the other to the hypsodonts (Cosoryx, etc.). A cornification of the integument in a fork horned Cosoryx produced Antilocapra, while the same process in a simple-horned Cosoryx produced Ovis. The development of this tj'^pe has undergone the three principal modifications indicated by the three genera which succeed upwards. In Sajga an extraordinary development of the muzzle takes place, which causes a change in the relations of the nasal bones. In Tetracerus another pair of horns is developed in front of *Die Kinder der Tertiiir-Epoclie ; Abli. Scliweiz. Pal. Gess., v, 1878. Cope.] ^'^O [Oct. 7- the usual pair. Bos develops complications of the molar teetb in both jaws. On the brachyodont side the development of the dermal covering of the horns of Blastomeryx is arrested, and naked horned types follow. In the Sivatberiine grouj) no further change follows except complication of the horns. In the Cervine group, on the contrar}^ the habit of shedding them becomes fixed, and a new family has its origin.* Of the Cervid^ or the Booidea which shed their horns, the genus Cervus is one of the earliest with which we are acquainted. Undoubted speciea of the genus occur in the Pliocene, and Upper Miocene species are also referred to it. As species from the Lower Pliocene (C matJieroni Gerv.) are referred to Capreolus, those of the Miocene may not be true Cervi. Their structure is not sufficiently known to determine this point. The arrangement of the genera is as follows. The three primary divisions were established by Brooke. I. Lateral metapodials complete only distally, and supporting deer claws (Telemetacarpi). a. Nasal passages posteriorly two, separated by vomer (Cariaci) Horns simple spikes Coassus Gray. Horns more or less furcate Gariacus Gray, Horns palmate Bangifer H. Smith aa.

The phylogeny of these genera cannot be fully known until the skele- tons of the extinct genera and species have been obtained. It is, however, certain that the short series of genera included in each of the three divisions (II a and «a, and HI), are genetic series ; and also that division I is ancestral to both II and III, although perhaps by an extinct genus differing in some respects from Moschus. These relations can be thus expressed : * I have described the probable mode of origin of the deciduous horns of the deer in Eeport U. S. G.

The next genus or stage presents branched horns, some - times of great complexity. The last term in each is the palmate horn, where a greater or less number of the tines unite to form a plate. These series, as is well known, correspond with the history of the growth of the horns in successive years of the life of each species. None of the genera of this family are extinct except Cervalces Scott. The following series may approximate a correct representation pf the phylogeny of the genus Bos, expressed in genera.

Note. — Pi'ofessor Gill has presented in his system of the Mammalia some reasons why the Suidoe should be more exactly defined than I have given above. In the Suina? and Phaochoerin* the postglenoid process is wanting or rudimental, and the mandibular condyle is flat and triangular. In the Dicotylinaj and Hippopotaminai the postglenoid process is well de- veloped and the condyle is subcylindric, as is also the case in Elotherium. I therefore place the two subfamilies named in a family separate from the Suidfe, under the name Hippopotamidae, to which it is possible that Elo- therium should be united as a third subfamily. Biographical Notice of Isaac Lea, LL.D. By Josepli Leidy, M.D., LL.D. {Read before the American Philosophical Society, November IS, 1SS7.) In accordance with the custom of this Society, which requires that a record shall be made of the claims of its deceased members to remem- brance, at the request of our President, I have prepared a brief sketch of one who was distinguished among us, our late much respected fellow- citizen and friend, Isaac Lea, LL.D. A more detailed memoir than the one I offer seemed supererogatory from the fact that only a short time previous to his death, there was published in the Bulletins of the United States National Museum, a volume containing a Biographical Sketch of Mr. Lea, comprising fifty-nine pages ; and a Bibliography of his publica- tions with a synopsis of the material therein contained, comprising 278 pages, prepared at the request of the Smithsonian Institution, by Mr. N. P. Scudder. To this source I have conveniently applied for much of the information of my notice. Isaac Lea was born March 4th, 1792, in Wilmington, Delaware. His grandparents, John and Elannah Lea, came from Gloucestershire, Eng- land, and accompanied William Penn in his second visit to this country. They were members of the Society of Friends, among whom they were noted as ministers. The father, James Lea, was a merchant, and at the age of fifteen Isaac went to Philadelphia to engage in a similar pursuit. In 1814, the country being at war with England, Isaac joined a volunteer 'rifle company, which oftered its services to the Governor of the State in case of need. As the services were not required, the company was soon disbanded ; but in consequence of Isaac joining it, he lost his birthright in the Society of Friends. At an early age Isaac showed a love for natural history, in which he was encouraged by his mother, who was herself fond of botany, and in- 1887.] 'Ik) I [Leidy. terested her children ia its study. At an early period also he became acquainted with Lardner Vanuxem, who had similar tastes, and together the young men studied mineralogy and geology, in the pursuit of which they made frequent excursions. In 1815 Mr. Lea was elected a m(*mber of the Academy of Natural Sciences of Philadelphia, which had been founded only three years pre- viousl3\ lie subsequently from time to time took an active part in the affairs of the institution ; and from his ample pecuniary means he liber- ally contributed towards its objects in the promotion of natural history. From 1853 to 1858 he occupied the position of President of the Academy. In 1817 he published in the Journal of the Academy the first of his nu- merous communications on natural history, entitled "An account of the minerals at present known to exist in the vicinity of Philadelphia." In 1821 jNIr. Lea was married to Miss Frances A. Carey, an accomplished lady, the daughter of Mathew Carey, a well-known publisher and a writer on political economy. He also became a member of the firm of M. Carey & Sons, which at that time was the most extensive publishing house in the United States ; and he continued with this and the successive firms until he retired from the business in 1851. Mr. Scudder remarks that few men have been more happy in their married life, which reached through fifty-two years, when the death of jMrs. Lea occurred, leaving her greatly afflicted husband together with two sons and a daughter. In 1838 Mr. Lea was elected a member of the American Philosophical Society, in which for many years he took an active part'; for some time serving as one of its Vice-Presidents and as Chairman of the Publication and Finance Committee. In the spring of 1833, together with his family, he went to Europe and visited England, France and Switzerland; returning the following autumn. In June, 1852, in company with his wife, daughter and sister, he again went to Europe, visited England, France, Germany, Austria and Italy, and returned in November, 1853. In these trips, while taking ad- vantage of the opportunity to examine and study the favorite subjects of his special research in the great museums, he was everywhere received with the most friendly attention by eminent naturalists and others. In 1853 Harvard University honored Mr. Lea with the title of LL.D. In 1860 he presided at the meeting of the American Association for the Advancement of Science, held at Buffalo, N. T. As an evidence of his continued interest in all that concerns the cause of natural science, when upwards of ninety-two years of age, at the nieeting of the Association and its guests of the British Association in Philadelphia, in September, 1884, he invited the members to visit him at his summer residence at Long Branch, N. J., where he had the pleasure of receiving and entertaining about two hundred. Mr. Lea, as usual with men of distinction who have made themselves known by their scientific labors, was enrolled as an associate in numer- ous learned societies abroad and at home. PROC. AMER.

Leidy.] 40^ [Noy. is, He reached the advanced age, within a few mouths, of ninety-five years, retaining to tlie last his intellect and his interest in his family, in science and everything that had rendered him happy during life. He died December 8lh, 1886. Mr. Lea was an enthusiastic student and an ardent lover of nature, and though like most other people occupied for many of the best years of his life with the exacting cares of business, he always found leisure success- fully to pursue his studies and investigations in natural history. He was especially interested in mineralogy, geology and palaeontology, but above all delighted in and devoted most time to the study of the fresh-water Mollusca, for which a favorable opportunity was afforded in the foct that the great rivers of this country are particularly rich in these animals and had been but imperfectly explored at the time of his taking up the study. To all the subjects. indicated and to others Mr. Lea has contributed to our knowledge ; but to the last one in an eminent degree not excelled by other naturalists. The record of this knowledge is contained in numer- ous communications, for the most part published in the Transactions of the American Philosophical Society and the Journal of the Academy of Natural Sciences of Philadelphia. Mr. Lea was a most acute and accu- rate observer and a most painstaking and conscientious investigator. Of the fresh-water and terrestrial Mollusca, Mr. Lea has described upwards of sixteen hundred new species of about fifty genera. The descriptions are given in the most comprehensive manner with exhaustive detail, and are accompanied with admirable illustrations. He was enabled to make this large contribution to our knowledge from the fact that his name be- came everywhere known as the leading authority in this department of concliology, and collectors in every land eagerly submitted to him all specimens supposed to be new or otherwise of scientific interest which came into their hands. Of Mr. Lea's labors relating to the extensive family of freshwater Mollusca, the Unionidic, Prof. Owen, of England, has expressed himself in the following words : "You have set a noble example of iDcrsevering devotion to the elucidation and making known to j^our fellow-men, of the portion of God's creation selected by your judgment, taste and opportu- nities for your studies. You will leave a grand and enduring monument of what one man may accomplish under such conditions, and I trust you may enjoy many years cheered by the retrospect of past labors, and by the grateful estimation in which they are held by the naturalists and lov- ers of science in both hemispheres." Mr. Lea's chief contributions to geology and palaeontology are found in the following works : Contributions to Geology. 8vo. Philadelphia, 1833 ; 227 pages and 228 figures. This is one of the earliest and most extensive contributions to a knowledge of the geology and fossils of the Tertiary formations of this country. The work relates to the formations of Alabama, Maryland 1887.] 403 and New Jersey, and contains descriptions of two hundred and twenty- eight new species of fossil Mollusca, together with a few other fossils. Notice of the Oolitic Formation in America, with descriptions of some of its Organic Remains. Published in the Transactions of this Society in 1841. It relates to the formation in New Grenada and Cuba, and con- tains descriptions and figures of upwards of twenty new species of Am- monites, Trigonia, Terebratuhi, etc. On Fossil Footmarks in the Red Sandstone of Pottsville, Pa., published in the Transactions of this Society in 18.53. An earlier notice is given in the Proceedings of 1819. In this is described the tracks of an amphibian vertebrate to which Mr. Lea gave the name of Sauropus primcBons. The fossil was discovered by Mr. Lea in the Red Sandstone of Formation No. 11, below the Coal Measures, of Roger's plan, of the Geological Survey of Pennsylvania. Tlie report of tlie discovery at the time excited consid- erable interest among naturalists from the circumstance that the specimen was the earliest evidence of the existence of air-breathing vertebrates. Description of a Fossil Saurian of the New Red Sandstone Formation of Pennsylvania. Published with illustrations in the Journal of the Academy in 1853. This gives a description of a saurian reptile to which Mr. Lea gave the name of Glepysaitrus peunsyUanicus, based on some fossil bones discovered at Milford, Lehigh county. Pa., the first at that time found in the Triassic formation of this country. Mr. Lea took the advantage of his opportunities to make a full collec- tion of the objects of his study and investigation, and this, with the ex- ception of the collection of Tertiar}'' fossils, which was presented to the Academy of Natural Sciences during his life-time, he has bequeathed to the National Museum at Washington, where it will be preserved for the study and admiration of future naturalists.

Prof. Edwin J. Houston made the following oral communi- cations : On a Non-Magnetizable Watch. C. A. Paillard, of Geneva, Switzerland, after some fourteen years' ex- perimentation, has succeeded in producing a watcli that is entirely desti- tute of any magnetizable material. The rapid growth of electric lighting and electric railways renders the magnetization of watches a matter of frequent occurrence, and the injury to the accuracy of time-pieces occasioned by inadvertently entering the magnetic field of the dynamo-electric machines, or motors producing the current, is well known. Heretofore a magnetic shield, consisting essentially of an iron-encasing box, has been employed to protect the works of the watch against the in- fluence of an external magnetic field. Such shields are, for the greater part, clumsy and heavy. Mr. Paillard's invention effects the protection of the watch in a much more thorough manner, and does so without rendering it any heavier. It will be seen that the problem Mr. Paillard set himself to solve, was ■i^^ [Nov. 18, to produce an alloy or metallic substance that possesses the following properties, viz : 1st. It must be non-magnetic. 2d. It must resist rusting and oxidation. 3d. It must be permanently elastic. These properties he has obtained in an alio}' of palladium. By the combination of two alloys containing different quantities of pal- ladium, Mv. Paillard has succeeded in obtaining accurate compensation for changes of temjierature in the balance wheels of his watches. On the Gramophone. Mr. Emil Berliner, of Washington, D. C, has recently made improve- ments in the speaking phonograph that, it would seem, will probably bring this instrument into everyday commercial use. These inventions are of such a character as, possibly, to a great extent, to render phonography, or short-hand reporting, one of the lost arts. There have been two causes for the failure of Mr. Edison's phonograph to come into extensive use. These are briefly : 1st. The perishable nature of the phonogram record, w^hich, being made on a sheet of tin-foil, was capable of reproducing the original sound a limited number of times only. 2d. The inability of the phonograph, as originally constructed, to cor- rectly reproduce the sounds spoken into it. The pitch or tone was cor- rectly reproduced, provided the point attached to the diaphragm of the receiving instrument was moved over the phonogram-record at the same velocity that it had while in the receiving instrument. The quality of the tone, on the preservation of whicli the ability to distinguish the speaker's voice depends, could not, however, be obtained to the extent a practical instrument demands. This arises not only from the fact that the original instrument failed to correctly impress on the phonogram-record the rela- tive intensities of the over-tones, on which the quality depends, but also on the fact that the receiving instrument was unable, from the relative positions these impressions bore to the surface of the phonogram-record, to always correctly reproduce them. These difficulties Mr. Berliner has, to a very great extent, overcome in an instrument called by him the gramophone. The direction in which these improvements have been made is mainly in the manner in which the receiving diaphragm of the instrument is caused to leave an impression of its movements on the phonogram-record. In the Berliner instrument, unlike the original Edison instrument, the to- aud-fro movements of the diaphragm are received by the plate in a direc- tion parallel to its surface, and not in a direction at right angles thereto. By this change the movements are recorded as a sinuous line of even depth, instead of a sinuous line of varying depths. It results from this difference that the resistance offered by the plate to the free movements of the transmitting diaphragua is reduced to a mini- 1887.] 421 mum, thus permitting much greater accuracy of the record received. At the same time the point attached to the receiving diaphragm has a positive motion in both directions, and can thus more correctly reproduce the characteristic quality of the spoken words. In any phonogram record made in a direction at right angles to the record surface, the fact that the resistance to impression does not increase in the same proportion as the depth of the impression will prevent the record from agreeing closely with the original tones. Loud tones must therefore fail to impress their characteristic quality on the phonogram- record, as correctly as more feeble tones. Mr. Berliner prepares his receiving surface as follows ; A plate of glass is covered with a layer of printers' ink, and then held in the smoky flame of a coal oil lamp and covered with a uniform layer of soot. On the sur- face thus prepared the stylus or point attached to the transmitting dia- phragm, makes its record of a uniform depth. It then only remains to fix the record so obtained. This is accomplished by the simple expedient of flowing the plate with any ordinary quick drying varnish. From this plate the sound can be directly reproduced, or a copy of it can be made on any desired metal. There are three ways in which the reproduction may be made, viz : 1st. By the simple process of mechanical engraving. 2d. By chemical deposition. 3d. By photo-engraving. This latter process is preferred by the inventor, the chromo-gelatine process being generally adopted. The Committee on the Michaux Legacy presented a report, accompanied hy the following resolution, which was, on mo- tion, adopted: " Resolved, That the sum of $200 be expended under the supervision of the Michau.K Committee, for the expenses of lectures of Prof. Rothrock, to be delivered in the Chapel of the University of Pennsylvania." The committee appointed October 21, 1887, to examine into the scientific value of the newly invented language, Yolaplik, and to report thereon, presented its report, which, after dis- cussion, was, on motion of Mr. Wmsor, made the special order for the next meeting of the Society, and the Secretaries were requested to have it printed and distributed among the resident members for inspection. And the Society was adjourned by the President. Boas.] 42^ [jjoy 18^ Notes on the EiJinology of British Colvmbia. By Dr. F. Boas. {Read hefore the American Philosophical Society, November 18, 18S7.) Note.— The Indian words are spelled according to the system used by the Bureau of Ethnology : q is the German ch in Bach ; c is the English sh. In the following remarks I intend to give a brief summary of the results of my journey in British Columbia. The principal purpose of my re- searches was to study the distribution of the native tribes, their ethnologi- cal character, and their languages. I arrived in Victoria in September, 1886, and spent most of my time among the natives of the east coast of Vancouver island and of the mainland opposite ; but in the course of my journeys I came in contact with several individuals of the Tlingit, Tsimp- shian, and Bilqula tribes, and I studied particularly the language of the last, of which I had obtained a slight knowledge from a number of men who w'ere brought by Captain A. Jacobsen to Berlin. Among the linguistic results of my journey the tnost interesting are the discovery of three unknown dialects of the Salish stock and the establishment of the fact that the Bilqttla, who are of Salish lineage, must have lived at one time with other Salish tribes near the sea. Though the culture of these tribes seems very uniform, closer inquiry shows that they may be divided into four groups — the northern one com- prising the Tlingit, Haida, and Tsimpshian ; the central comprising the Kwakiutl and Bilqula ; the sottthern comprising the different tribes of the Coast Salish ; and the tribes of the west coast of Vancouver island. All these tribes are divided intogentes ; but, while among the northern tribes, the child belongs to the gens of the mother, among the southern ones it belongs to that of the father. The arts, industries, folk-lore, and other ethnological phenomena of these groups are also different, and the groups have evidently influenced one another. I shall first show some of these differences by considering the folk-lore of a few of these tribes. The principal legend of the Tlingit is the well-known raven myth. It is not necessary to dwell upon this myth, as it is known by the reports of many travelers. Vemiauow, who lived for a long time among the Tlin- git, considers the raven as their supreme deity. It appears from the myths which I collected that besides the raven the eagle is of great im- portance. One of the legends tells how the raven obtained the fresh water from a mighty chief called Kanuk. This Kanuk is identical with the eagle. Traces of the raven legend are found among all tribes as far south as Koraoks. The Kwakiutl consider the raven the creator of the sun, moon, and stars. The raven legend is not found among the Salish tribes ; their supreme deity is the sun, who is called by the Skqomic the great wandering chief, and a greatnumberof myths refer to him. Among the northern tribes of this group and among the Kwakiutl the identity of the sun and the deitj^ is not 1887.] 4-0 [Boas. SO clear ; they call the latter Kants'oump (that is, "our father"), or Ata ("the one above "), or Kikarae ("the chief"). His son, Kanikila, de- scended from heaven to the earth, and was born again of a woman. When he was grown up, he traveled all over the world, transforming men into animals, and making friends with many chiefs. The same legend is known to the Salish and the West Vancouver tribes. The Komoks call the deity Kumsnootl (that is, "our elder brother ") ; the Kauitcia, Qiils ; the West Vancouver tribes. Alls. He is their culture-hero. In the south- ern part of Vancouver island it is said that he gave men the fire. The Kwakiutl say that he created the salmon, and gave the law of the winter dance. These two traditions — the raven legend and the legend of the sun and the son of the deity — are mixed in numerous tribes, particularly among the Kwakiutl. The Bilqula, on the other hand, have both these legends, but a third oAe in addition. They say that four men — Yulatimot, Mas- masalaniq, Matlapalitsek, Mallapeeqoek — descended from heaven after the raven had liberated the sun. Then the tradition goes on : And Yulati- mot thought, "Oh, might INIasmasalaaiq carve men out of cedar !" and Masmasalaniq carved men ; and Yulatimot thought, " Oh, might Masmas- alaniq make a canoe !" and Masmasalaniq made a canoe, etc. Yulatimot gives Masmasalaniq his thoughts, and Masmasalaniq accomplishes them. Thus these two spirits created men and gave them their arts. It is remarkable, however, that by some individuals Yulatimot is described as the raven himself, and he is represented in this way in masks, paintings, and carvings. From these few remarks it will appear that the mythology of each tribe can only be understood by studying it in connection with that of his neighbors. Certain mythological ideas, however, are common to all tribes of the north-west coast. The myth of the creation of the world is very uniform among all tribes. The northern group say that in the beginning it was dark until the Raven liberated the sun. The southern tribes say that there was a sun from the beginning, but that daylight was kept in a box by the chief of the sun, and that it was liberated by the Raven. After it had become light, the earth, trees, fire, and water were made. It is remarkable that all these were obtained from some chief who retained them for his own use. Nothing was created. Thus the earth was pre- pared for man, who descended in the shape of birds from heaven. When they arrived on the earth, the' birds threw off their skins and became men. These became the ancestors of the genles, and each of them received a certain tract of land when the great transformer, Kanikila, met him. Subdivisions of the gentes derive their origin from one of the de- scendants of these first men. It is told, that in olden times certain men descended into the sea, or went up the mountains, where the}'^ met with some kind of spirit, who gave them his emblems. Thus they became the ancestors of subgentes. Boas.] 4-i4: j-j^oy 18, Before Kanikila's arrival, animals had the shape of men ; but even after they were transformed they were able to appear in the shape of men by taking off their blankets. The northern tribes who do not know the great transformer, say that men were transformed into animals at the time of the great flood. All tribes consider the sky a solid vault, which can be reached in the far west. After having crawled through a hole in the sky, another land is found, with forests, mountains, ponds, and lakes, in which the Sun and many other spirits live. There is another very remarkable way of reach- ing this land. Tlie man who intends to go there takes his bow and shoots one arrow into the sky ; then he shoots another one, which sticks in the lower end of the first one ; and so he goes on shooting until a chain is formed reaching from heaven to earth. I believe that this tradition be- longed originally to the tribes of the Salish stock. The Okanagan myth told by Gatschet in Globus, 1887, Vol. 52, No. 9, belongs to this group of legends. It is told in a great number of modifications among the tribes of Vancouver island and the neighboring coast. One of the most important of these is : How the Mink, the son of the Sun, visited his father. This tradition is told by the Kwakiutl and Bilqula. Mink made a chain of arrows reaching to the sky, and climbed up. When he arrived in heaven he found his father, an old man, sitting near the fire. The fiither was glad to see him, and asked him to carry the sun in his stead. Mink com- plied with this request, and next morning his father gave him his nose ornament, the sun, and said to him, "Do not go too fast, and don't stoop down, else you will burn the earth." Mink promised to obey, and ascended slowly his path ; but when it was near noon, clouds obstructed his way. He got impatient, and wanted to see what was going on, on the earth. He began to jump and to run and stoop down ; then the earth began to burn, the rocks to crack, and the ocean to boil. When IMink's father saw that his son disobeyed his orders, he pursued him, tore him to pieces, and cast him into the ocean. There he was found by two women. Another interesting tradition is told by the Komoks, which in some respects resembles a well-known myth of the Tlingit. In olden times the gum was a blind man. He used to go out fishing during the night, and early in the morning his wife called him back. One day, however, she slept too long, and when she came down to the shore the sun was high up in the sky. She called her husband, but before lie could return he had melted. His sons wanted to revenge his death, and made a chain of arrows reaching from heaven to earth. They climbed up and killed the Sun with their arrows. Then the elder brother asked the younger one, " What do you intend to do?" He said, "I will become the moon ;" the elder one said, "And I will become the sun." Another remarkable tradition is told by the same tribe. The sou of the Sun ascended a chain of arrows into heaven, and married Tlaiq's daugh- ter. Tlaiq tried to kill his son-in-law, but did not succeed in his attempts. The latter, in revenge, killed Tlaiq. I consider the last-mentioned tradi- 18S7.] 425 [Boas. tions of great importance, as both evidently refer to tlie killing of the old sua and the origin of the new one. Visits to the Sun, or to the deity which lives in heaven, are frequent in the folk-lore of all these tribes. The Kwakiutl, for instance, tell of a chief 's son who ascended to heaven and married the deity's daughter. Their son was the Eaven. The fact that the same mythical beings are known to a great number of tribes shows that the folk lore and myths of the tribes of the north- west coast have spread from one tribe to another. The raven legend seems to have belonged to the Tliugit and their neighbors, but traces of it are found far south. On the other hand, the sun legend seems to have originated with tribes of Salish lineage ; but parts of this tradition are at the present time told by their northern neighbors, and faint traces are even found among the Tsimpshian and the Tlingit. A number of spirits occur in the folk-lore of most of the tribes of North- west America. One of these is the Tsonokoa, who is evidently a mythi- cal form of the grizzly bear. She is a woman living on high mountains, or, in some instances, in heaven. She visits the villages in order to steal fish, which she puts into a basket that she carries on her back. One tra- dition says that a man wounded and pursued her. At last he arrived at her house in heaven. He was called in in order to cure her, and did so by extricating the arrows, which none of her companions were able to see. In reward she gave him her daughter, the wate;^- of life, and the fire of death, and on his return he became a mighty chief. Another spirit, which is known from Komoks to Bilqula, is Komokoa, a water spirit, the father of the seals. Many legends tell of men who visited him, or of his visits to villages where he married a woman and became the ancestor of certain gentes. The Sisiutl, a double-headed snake, is known to all tribes from Puget Sound and Cape Flattery to the northern tribes of the Kwakiutl. It is the emblem of many gentes, and its most remark- able quality is that it can assume the shape of any fish or snake. I have to say a few words about the dances, particularly the cannibal dances, of these tribes. The legend ascribes the origin of the latter to a spirit, Baqbakualanusiuae. This being lived in the forest. Once a man came to visit him, and when the spirit was about to devour him, he made his escape, Baqbakualanusiuae pursuing him. When the spirit had almost reached him, he threw a stone behind him, which was transformed into a large mountain. The pursuer had to go all around it, but again he approached. Then he poured out a little fishoil which he chanced to carry. It was transformed into a lake. Again the spirit approached, and now he threw down his comb, wliich was transformed into a forest of young trees. He reached his house, and locked the door. When the spirit arrived, he gave him a vessel filled with dog's blood, and said, "Come in. This is my son's blood. You may eat him. " But when the spirit accepted the invitation, he threw him into a pit, which he filled with fire, and thus killed him. His ashes were transformed into mosquitoes. PROC. AMER. PHILOS. SOC. XXIV. 126. 3b. PRINTED DEC. 7, 1887. Boas.] 4-0 ^-^Qy^ Ig^ Besides this spirit, tlie crane, and the so-called "Hatnaa, " can become the genii of the cannibals. The right to become cannibal is hereditary in certain gentes, but every individual has to acquire it by being initiated. For this purpose he goes into the woods, where he lives for three or four months. After this time, he approaches the village, whistling and sing- ing ; then the people know that he has become a cannibal (Hamats'a). The next morning they go into the woods in order to fetch him back. They sit down in a square and sing four new songs which are composed for the occasion. The first song has a slow movement, the second is in a five-part measure, while the third and fourth have a quick movement. As soon as these are sung, the new Hamats'a makes his appearance. He is surrounded by ten men, who carry rattles, and is accompanied by them to the village. All those partaking in the ceremony wear head-rings and neck-rings made of hemlock branches. Four nights the new Hamats'a dances in the house of his father. On the fourth night he suddenly leaves the house, and after a short time returns, carrying a corpse. As soon as the old cannibals see this, they rush forward and cut the corpse to pieces, which they devour. This custom is principally practiced among all tribes of Kwakiutl lineage ; but it is also found among the Bilqula and Komoks, who have evidently adopted it from the Kwakiutl. Similar customs pre- vail among the Tsimpshian. G. M. Dawson says that they have four dilferent systems of rites of religious character, which he calls Simhalait, Mihla, Noohlem, and Hoppop. The third of these are dog-eaters, while the last are the cannibals. According to my inquiries, this refers to the following tradition : A man went out hunting. After some time he saw a white bear, and pursued it until it disappeared in a mountain. The hunter followed him, and saw that it was transformed into a man, who led him through his house, which stood in the interior of the mountain. There he saw four groups of men, and what they were doing. The first were the Meitla, the second were the Nootlam ("dog-eaters"), the third were the Wihalait (" the canni- bals"), and the fourth were the Semhalaidet. Four days the man staid in the house. Then he returned ; but when he came to his village, he found that he had staid in the mountain four years. The bear had told him to do as he had seen the men in the mountain doing. Since that time the Tsimpshian eat dogs and bite men. There are no reports that cannibal ceremonies exist among the Haida and Tliugit. The masks which all these tribes use in their dances represent spirits or some of the heroes of their legends. Most of the winter dances are pan- tomimical performances of their traditions. At the great feasts other masks are used, which refer to the tradition of the gens of the man who gives the feast. The use of masks is most extensive among the northern tribes. The variety of masks of the Haida, Tlingit, Tsimpshian, and Kwakiutl, is wonderful, but the more southern tribes have only a very limited number. Among the Nanaimo their use is the privilege of certain gentes. The Lkungen of Victoria use only very few masks, which they destroy by fire as soon as a death occurs in their tribe. 1887,] 4^7 [Boas. Besides the dances and the use of masks, other customs are common to all tribes of the noith-west coast. One of the principal of these is the use of copper-plates. These have frequently been described as being used instead of money, but this is not the case. Tliey are manufactured from copper found on the upper Yukon, and given as presents by one tribe to another. The Indians value a copper-plate the more, the more frequently it has been given as a present. Every single plate has its name and its own house, and is fed regularl3^ No woman is allowed to enter its house. Almost every tribe has a tradition referring to their origin. Some say that a man who visited the moon received it from the man in the moon. Others say that a chief living far into the ocean gave it to a man who came to visit him, etc. Similar legends refer to the Haliotis shells which are used for ear and nose ornaments and bracelets. The so-called Potlatch is a feast celebrated by all these tribes. A chief invites all his neighbors, sometimes to the number of a tliousand and more, to his house, and presents every one with blankets, skins, and nowadays even with money. The Salish tribes have a kind of scaffold in front of their house, which is used at these festivals. The chief and two of his slaves are standing on it, and distributing the blankets among the guests. Small festivals of this kind are celebrated very frequently. An Indian who has been unsuccessful in hunting, and feels ashamed on this account or for any other reason, gives such a festival to restore his honor. In the beginning of these feasts four songs are sung, and four different kinds of dishes are served. Then one of the guests stands up and praises the liberality of the host, who, in his turn, replies, praising tlie deeds of his ancestors. In this speech he frequently uses a mask representing one of his ancestors. I mentioned above that the social institutions of the northern group and those of their southern neighbors are different ; therefore their mortuary customs and marriage ceremonies are also different. The northern tribes burn the corpses of all men except medicinemen. These are buried near the shore, and the corpse of the son is always deposited on top of the corpse of his father. It seems that some of the Kwakiutl tribes used to burn their dead ; but by far the greater number of tribes of this stock either hung up the dead in boxes in top of trees, the lower branches of which were removed, or deposited these boxes in burial-grounds set apart for this pur- pose. Chiefs are buried in a separate place. Food of all kinds is burned for the dead on the shore. I shall describe their mourning ceremonies as illustrative of those in use of most of the coast tribes. The mourning lasts for a whole year. For four days the mourner is not allowed to move. On the last of these days all the inhabitants of the village have to take a bath. On the same day some water is warmed and dripped on the head of tlie mourner. For the next twelve days he is allowed to move a little, but he must not walk. Nobody is allowed to speak to him, and they believe that whosoever dis- obeys this command will be punished by the death of one of his relatives. Smith.] "^y [Nov. 18, He is fed twice a day by an old woman, at low water, with salmon caught in the preceding year. At the end of the first month he deposits his clothing in the woods, and then he is allowed to sit in a corner of the house, but must not speak to the other people. A separate door is cut, as he is not allowed to use the house door. Before he leaves the house for the first time, he must approach the door three times and return without going out. Then he is allowed to leave the house. After four months he may speak to other people. After ten months his hair is cut short, and the end of the year is the end of the mourning period. After the death of a chief, his son gives a great festival, in which he takes the office and name of his father. At first, four mourning songs are sung, which have a slow movement, and then the son of the chief stands up, holding the copperplate in his hand and saying, " Don't mourn any more. I will be chief. I take the name of my father." The marriage ceremonies of the Kwakiutl tribes are very remarkable. The dowry of the bride consists of bracelets made of beaver toes, copper- plates, so called " button- blankets, " and the Gyiserstal. The latter is a board, the front of which is set with sea-otter teeth. It is intended to represent the human lower jaw ; and the meaning is, that the bride will have to speak or be silent, as her husband may desire. Before and after the marriage, the sou-in-law gives many presents to his wife's father. If the woman intends to return to her parents, her father must repay all he has received from his son in-law. This is done frequently, in order to give an opportunity to the father-in-law to show his liberality and wealth. As soon as he has paid the husband, the latter repurchases his wife. The use of the Gyiserstal is very limited. I found it only among the Kwakiutl proper and Nimkish. I do not intend to describe the houses, the hunting and fishing, and industries of all these tribes, neither will I attempt to discuss the character of the art products of the different groups. I Jiave endeavored to show in my remarks that the culture of the Northwest American tribes, which to the superficial observer seems so uniform, originates from many differ- ■ent sources, and that only a thorough knowledge of the languages, folk- lore, and customs of these tribes and their neighbors will enable us to trace at least part of their obscure history. Electrolysis of Lead Solutions. Determination of Boric Acid. Dihnlogen Derivatives of Salicylic Acid. Barite. By Edgar F. Smith. (Bead before the American Philosophical Society, Nov. ISth, 1SS7. ) The following is a report of work prosecuted in the laboratory of Wit- tenberg College, Springfield, Ohio, during the past year, partly by myself and partly by students under my supervision : I. Electrolysis of Lead Sohitions. Lead is one of the metals which has given analysts considerable trouble 1887.] 4:2J [Smith. to estimate eleclrolyticallj^; cousequently, many suggestions have been oifered, as to the best course to pursue in determining it in this manner. In this note I purpose giving some results obtained by using an alkaline solution of lead containing a phosphate. Employing a lead solution witli an unknown quantity of lead, I took from it, 5 c.c, to which I added an excess of disodium phosphate, dissolving the precipitate formed in sodium hydroxide, then subjected the liquid to the action of a current derived from three small Grove cells, for a period of two hours, after which the action was interrupted ; the deposit of metallic lead was washed with water, alcohol and ether, then carefully dried and weighed. In tliis man- ner I obtained .0105 grs. Pb. A second experiment conducted under like conditions gave a similar result. With 10 c.c. of the lead solution the following amounts of lead were obtained : 1. .0210 grams Pb. 3. .0213 grams Pb. 2. .0215 " " 4. .0210 " The same current strength was used in all these determinations, but the time varied from two to four hours. In all instances, the precipitated metal showed a regular, compact appearance. I analyzed another lead solution of unknown strength, using, as before, sodium phosphate and hydroxide, and obtained : .0225 grams ) p,^ .0217 " / The current was from three small Grove cells. Time, 3^ hours. Subsequently, I dissolved 8.7815 grams of lead nitrate in 350 c.c. water, and treated as follows : 1. One c.c. of the solution was precipitated by sodium phosphate, the precipitate dissolved in sodium hydroxide and the solution exposed to the action of a current from two Grove cells for two hours. In this way I obtained a lead deposit equal to .0215 grams Pb. The metal, after being ■washed with water, was dried in a current of hydrogen. This seemed necessary and was done in the following determinations : 2. Same as in 1 ; obtained .0220 grams Pb. 3. Same as in 1 ; obtained .0213 grams Pb. 4. Same as in 1 ; obtained .0220 grams Pb. The theoretical amount of lead in the electrolyzed solution was .0219 grams. These experiments indicate that the metal can be deposited in good form from an alkaline phosphate solution, but to insure satisfactory results, great care must be exercised in the drying, as the moist metal oxidizes readily. II. Experiments in the Determination of Boric Acid. By E. B. Enerr. It was observed that a considerable quantity of uranium nitrate could be added to a borax solution containing potassium ferrocyauide before the Smith.] 430 [Nov. 18, characteristic red-brown precipitate of uranium ferrocyanide appeared. Tliis suggested the possibility of obtaining a quantitative method for the estimation of borii acid. I, therefore, dissolved 4.18 grams of uranium nitrate in one litre of water, and 1.16 grs. of well- crystallized borax in 250 c.c. water. The uranium solution was then placed in a burette and carefully added to definite portions of the borax solution until a drop of the mixture, added by means of a thin glass rod, to a drop of a concen- trated potassium ferrocyanide solution, on a porcelain plate, gave a red- dish-brown color. The first distinct coloration was regarded as the final reaction. The following results were obtained : 1. 5 c.c. of the borax solution required 8.8 c.c. uranium nitrate. 8.9 " 3. 4. 5. 6. " •' " " 8.8 " 7. 10. 10 c.c. 11. ^.8 " 17.7 17.6 A second uranium nitrate solution, containing 8.6267 grams nitrate in 500 c.c. of water, was standardized as above with a borax solution (con- taining .9051 grams borax in 250 c.c. water). The results were as follows : 1. 5 c.c. borax solution required 1.85 c.c. uranium nitrate. 2. " 3 ,. 4. " 5. " " " " " " From this we discover that 1 c.c. of uranium solution equaled .004917 grams B2O3. To test the accuracy of the method, I dissolved 1.1762 grams freshly crystallized borax in 250 c.c. of water, and titrated portions of it with the above standardized uranium solution: 1. 10 c.c. of borax solution required 4.0 c.c. uranium solution. 3.5 " 3. " " " 3.4 " 4. " " " 3.5 " 5. 6. 7. 1887.] 431 [Smith. Taking 10 c.c. of the borax solution as equivalent to 3.5 c.c. of the uranium solution, we Iiave the 250 c.c. of the borax solution equal to 85 c.c. of the uranium solution ; but the 85 c.c. represent 85 x .004917 grms. B^O., = .43023 grms. B.A or 36.57%. The theoretical amount of boric acid in 1.1767 grms. borax is .48114 grs. BjOg or 36.64%. Free acid very materially affects the results. Extremes of dilution also influenced the same to a certain degree. I next endeavored to ascertain how ferric salts would act upon borax. At first, potassium ferrocyanide was employed as an indicator, but was later rejected. On substituting potassium sulphocyanide for it, a few drops of the same were placed in the vessel containing the borax. The first decided "blush" which came over the solution was counted as the end of the reaction. I standardized a definite amount of ferric ammo- nium sulphate with a definite quantity of borax, finding that one c.c. of the iron solution was equivalent to .004479 grams B.fi^. I then dissolved 1.2651 grms. of borax in 250 c.c. of water, and titrated a number of por- tions with the standardized iron solution. The results were 36.73% B^Oj, instead of 36.64% bj- theory. Upon standardizing a new quantity of iron salt, instead of adding the sulphocyanide solution directly to the borax solution, a few drops of it were placed upon a porcelain plate, and as the end reaction was approached, portions of the liquid were brought in contact with the sulphocyanide by means of a glass rod. In this way the following numbers were ob- tained ; 1. 10 c.c. borax solution required 1.05 c.c. iron solution. 3. 5 c.c. " " 0.5 " 4. 10 " " " " " 5. 5 " " " 0.5 " 6. 10 •" " " 1.05 " 7. " •' " " " " 8. 20 " - " 2.10 " 9. " " " " " " " 10. 40 •' " '• 4.20 " Thus, I found that one c.c. of the iron solution was equal to. 00967 grms. B2O3. The following tests were then made with the iron solution : 1. 2.2741 grms. borax were dissolved in 250 c.c. of water, and portions of it titrated : 10 c.c. borax required 3.40 c.c. iron solution. 20 " " " " This gave 36.14% BA ; theory 36.64%. Smith.] 4:0 J ^^^^^ 18_ 2. Six determinations were made with a solution containing 2. 1490 grms. borax in 250 c.c. water. Found 36.40% B.fi^, instead of 36.64%. 3. With a solution containing .0865 grms. of borax, I obtained 86.89% B2O3. 4. .0254 grms. borax, dissolved in water and titrated, showed 86.46% B2O3, instead of 36.64%. 5. .0104 grms. borax gave 37.50% B2O3. 6. .0198 grms. borax, titrated as before, gave 36.35% BjOj. A number of determinations showed that sodium salicylate can also be advantageously employed as an indicator. For rapid work, where approximate results are sufficient, the foregoing methods will no doubt be of service. Free acids should always be avoided. I have also experimented with tuogstic and molybdic acids in the same manner, and while the results are very promising, I prefer reserving an account of the same until the details have been fully worked out. III. Dihalogen Derivatives of Salicylic Acid. By W. S. Uoskinson. In the American Chemical Journal, Vol. viii, No. 2, Smith and Knerr described metachloriodosalicylic acid and* its derivatives. Pursuing a somewhat similar line of research, I prepared a brom chlor acid, and an iodo-brom -salicylic acid, as well as derivatives of the same. Below I give a brief description of these new compounds. Bromclilor-salicylic Acid. CgH^ OH BrCl COOH. To obtain this acid I used a definite quantity of metachlorsalicylic acid (m.p. 172° C), and dissolved the same in alcohol. To this solution was gradually added a corresponding, equivalent amount of bromine ; the flask in which the reaction was performed was kept cool. When the entire quantity of bromine was added, the alcoholic solution was evapo- rated to dryness upon a water-bath. The residue was boiled with water and barium carbonate, the liquid filtered and allowed to cool. The barium salt separated in bushy needles. Its solubility in water is about 1 : 100. The sodium salt was prepared from the barium salt, and from it the acid was liberated by hydrochloric acid. The free acid forms small, white needles, nearly insoluble in boiling water, but soluble in alcohol. In its pure state it melts constantly at 229° C. The barium salt [(CgH, OH BrCl CO)^ Ba + 4HjO] forms long bushy needles, soluble with difficulty in boiling water. An analysis of it gave 10.02% HjOand 21.20% Ba. The formula given requires 10.14% HjO and 21.48% Ba. The sodium salt (CgH^ OH BrCl COONa + 1^ H^O) appears in beau- tiful bunches of white needles, which are very soluble in water. An 1887.] ^^^ [Smith. analysis showed 9.09% H,0 and 8.25% Na ; theory" requires 9.89% HjO and 8.40% Na. The calcium salt is anhydrous. Its analysis gave 7.42% Ca, while theory requires 7.39%. The zi}ic salt forms small crystals, much like fish-eggs. It dissolves with difficulty in hot water. When analyzed it gave 13.91% HjO and 12.24% Zn ; the theoretical figures are 14.06% H2O (5 molecules), and 11.94% Zn. The magnesium salt does not crystallize well. It is not readily soluble, even in hot water. It contains six molecules of water of crystallization. Upon analysis I obtained 17.19% HjO and 5.33% Mg. The calculated percentages of waler and magnesium are 17.03% and 4.79%. The cadmium salt forms beautiful crystals. The silver salt was obtained as a white precipitate insoluble in water. I employed it in preparing the methyl and ethyl esters. MetJiyl Ester [C^U^ OH BrCl CO OCE^). This was obtained by the action of methyl iodide upon the silver brom-chlorsalicylate. It forms beautiful needles, dissolving with difficulty in both alcohol and ether. It melts at 126-127° C. This ester was burned with lead chromate, and gave good results. The etiiyl ester, also prepared, was not further studied. The free brom-chlor acid was burned with lead chromate. The result showed 33.07% carbon and .96% H. Theory requires 33.46% C and 1.53% H. lodo-hrom-salicylic Acid. CfiH^ OH IBr COOH. Metabrom-salicylic acid was first prepared, and then iodated by the method of Weselsky. Little heat was evolved in the reaction ; sometimes this was added by means of the water-bath. When the reaction was com- plete the alcoholic solution was removed to an evaporating dish and run down to dryness. The residue was boiled with water and barium car- bonate ; from the hot filtrate the barium salt crystallized out, but it was immediately converted into the sodium salt, from which I set the acid free. The latter forms small, beautiful needles, dissol"v^ing with difliculty in hot alcoholic water. It melts at 208-209° C. A combustion of the pure acid gave 24.17% carbon and 1.30% H, instead of 24.48% C and 1.17% H. The barium salt contains three molecules of water. It forms branched, purple-tinted needles. An analysis gave 6.48% HjO and 15.55% Ba, in- stead of 6.27% H2O and 15.65% Ba, as required by theory. The sodium salt contains one molecule of water. It forms nodules, consisting of silky needles, very soluble in water. When analyzed it yielded 5.20% H2O and 6.08% Na ; theory requires 4.70% H^O and G.30% Na. The calcium salt resembles the barium salt in form ; it is possibly some- what more soluble in hot water. It contains four molecules of water. Its PROC. AMER. n'HILOS. SOC. XXIV. 126. 3C.

Its analysis showed 8.21% HjO and 14.13% Cd, instead of 8.29% HjO and 14.19% Cd. The zinc salt consists of indistinct needles, readily soluble in water. Its analysis showed the presence of five molecules of water, and 10.51% Zn. The methyl ester crj^stallizes in beautiful needles, which melt at 104- 105° C. By its combustion I obtained 26.23% C and 2.15% H. Its for- mula requires 26.86% C and 1.68% H. The study of other mixed dihalogen derivatives of salicylic acid is being carried forward in this laboratory, the results of which will be published later. IV. Barite from Ludlow Falls, Miami County, Ohio. By Charles H. Ehrenfeld. This mineral was found in the summer of 1886, the chief interest in connection with it being that it is the first time barite has been found in this locality. It is white, semi-transparent and massive, and it occurs in the Niagara limestone, associated with small crystals of pyrite, the surface of which is brown owing to oxidation. The average of four sp. gr. deter- minations of the barite is 4.48.

Note on tJie Possible Existence of Fireballs and 3Ieteorites in tJie Stream of Bielids. By Daniel Kirkwood. {Bead before the American PhilosopJdcal Society, December 2d, 1SS7.) A revision of my paper on this subject, read September 2d, 1887, sug- gests the following modifications : 1. Before 1832, the earth passed the comet's node early in December. The first eight meteors of the list should therefore be rejected. 2. In Greg's Catalogue the circumstances which indicate the radiant are not generally given ; the probability that the meteors belong in part to the stream of Bielids must be judged by a comparison of their relative num- bers with the mean number during a specified time. In the thirty years from 1831 to 1860, the list gives seven hundred and twenty-one fireballs and meteorites, or six for any three days of the year taken at random. The number for November 28-30 is twelve, or twice the average. Of these, one is the meteorite which fell during the shower of Bielids on November 27th, 1885 ; one is the conformable fireball of November 28th, 1850, the date of a well-marked shower of shooting stars ; three (1839, 1848, and 1850, Nov. 30) are non-conformable ; and the directions of the remaining seven are unknown, at least to the writer. Mr. Greg calls attention to November 27-30 as an aerolitic epoch coincident with one of shooting stars. 8. The attempt in my paper of September 2d, to trace a period approxi- mately equal to that of Biela's comet was probably premature. Proceedings llmer. Philos. Soc, 1887.] 4d7 [Briiiton. On on Ancient Human Footprint from Nicaragua. By D. G. Brinton, M.D. {Read before the American Philosophical Society^ Nov. 18/^,1 SSt.) The discovery of human footprints in volcanic rocks near the shore of Lake Managua, Nicaragua, under circumstances which seemed to assign them a remote antiquity, has been announced for several years.* We owe thanks especially to Dr. Earl Flint, of Rivas, Nicaragua, for information about this discover^', and for sending several specimens to the United States. Four of these are in the Peabod}^ Museum of Archaeology, Cambridge, and recently, I have myself received one from Dr. Flint, to- gether with several letters describing the locality. The posses- sion of this material has induced me to present, along with its description, a general review of the subject. The surface of the Republic of Nicaragua presents in nearly all parts the signs of enormous volcanic activity. It is broken by a complex series of mountain ranges whose sides are scored wnth vast lava streams. Frequent earthquakes attest the con- tinued energy of the subterranean forces and prepare us for incidents of elevation and subsidence on an uncommon scale. The great lakes of Nicaragua and Managua are divided by a low plain through which flows the river Tipitapa connecting these sheets of water. South of this lowland rises a mesa or table- land 400 or 500 feet above the level of the lakes, and upon this stand the volcanic cones of Mombacho (4588 feet) and Masaya (2972 feet). Beyond these, the land still rising, reaches its height in the Sierras de Managua, presenting the craters of the extinct volcanoes of Tizcapa, Nezcapa (Nehapa^,and- Asososco ; and further to the north-west, immediately upon the shores of the Lake Managua, the still smoking peaks of Chiltepec (2800 feet) and Momotombo (6121 feet). The last named (Momotombo) was active in 1852, and Masaj-a in 1858 and 1872, w4iileMombacho,though quiet, so far as we know, since the conquest, according to tradition, destroj^ed an impor- tant town just before that epoch, and its sides still reveal signs * The following are the p'iiicipal references : Letter of Dr. Flint, dated Jan. 7, 1884, in the American Antiqnwinn, March, 1881 ; Vith Report nf the Peahody Museum for 1884, page 356; 18 inches, the breadth at the heel 3 inches, at the toes 4i inches. The apparent length of the foot itself was 8 inches. The instep was high, and the great toe large, prominent and exceeding in length the second toe. This last peculiarity has been by some considered of ethnic import- ance.* The greatest depth of the impression is at the ball of the foot, the weight being evidently thrown forward as in vigor- ous walking. At this part the maximal depression below the plane of the superfices is 2 inches. The footprints on the tufas at Managua are not the onl}^ ones discovered in tiiat Republic by Dr. Flint. Others were seen on the southern slope of the Sierra de Managua, near the town of *See J. Park Harrison, " On the Relative Length of the First Three Toes of the Human Foot," in the Journal of the Anthropological Institute of Great Britain, February, 1884. The general conclusion seems to be that a long second toe indicates a lower stage of develop- ment . 1887.] 44d [Brinton. San Rafael. The character of this horizon is thus described by Dr. Flint in a letter to me : " Collateral evidence touching man's antiquity here, not less weighty, is found in the neighborhood. The eruptions covering the south-west slope, and the disturbance caused by one, along the ocean beach, elevating the coast range, affords us indisput- able evidence of Pliocene man. In descending the slope through immense ravines formed b}' the annual floods, we see enormous blocks of tufa, isolated by the removal of the material surround- ing them, showing that they had been uplifted by some mighty force and re-embedded in the resultant debris. " In 1875-8 and 1883, I spent over a month visiting the coast- hills to the south-west about San Rafael, seeking out the limits of the cataclysm. " A strip of land, commencing at Bocano, extends along the coast about forty miles and widens out about San Rafael, termi- nating some eighteen miles above the latter place, at the base of the old primitive range. South-east of the town, a notable break in the upheaval shows that this strip was undisturbed, while the succession of hills to the east and south-east widens out and extends to the south at San Juan del Sur, and thence to Salinas bay. The force culminated against the south-west slope of the old primitive volcanoes mentioned, also shown north-west of San Rafael, where the tufa of the first eruption, on the slip of land mentioned, was unbroken, while in ravines near, the ocean sedi- ment of the upheaval overrides it, forced over it as the rise occurred near b}'^ to the east. " This sediment has been carried seaward by the rivers since formed. As they removed the debritus from the tufa, these were found covered with footprints of animals and man. One of these (sandal shod) was forwarded to the Peabody Museum. " Where the rivers have cut through the old sea sediment down to the primitive rock, we see beds of shells of many species, among them enormous oysters of an oblong figure, perfect fossils, yet unnamed. They are in situ. Their contents resemble slaked lime. All this shows a sudden elevation. A few can be seen at the National Museum with the fossil leaves in the rock above them, similar to those on the Managua clay under the ash erup- tion. The latter eruption broke up the clay and elevated the 4i4 [Dec. IG, coast range. On the neigliboring hills innumerable shells are adherent to the fractured limestone, and south to those west of Rivas ; from there the limestone dips to south-east and is only about sixty metres above the sea between San Juan and Virgin bay, while part of the Rivas plateau was undisturbed." It will be observed that one of these footprints indicates the use of sandals or moccasins by the pedestrians of that day. None of this character have been reported from Managua, Un- doubtedly a society which wears shoes cannot be assigned to the earliest stages of human culture. Many of the natives of Cen- tral America to this day never protect the feet in any manner. In conclusion, I should say, that there can be no doubt of these being genuine human footprints. They are not of that mythical origin which the fancy of savage nations delights to imagine,* nor can there be the least doubt of their authenticity. Their antiquit}^ remains uncertain. In regions at once tropical, fertile and volcanic, we may expect sudden upheavals and sub- sidences, and the ravages of the most violent outbursts are re- paired by a luxuriant vegetation with surprising rapidity. My own opinion is, that there is not sufficient evidence to remove them beyond the present Post-pliocene or Quaternaiy period. Stated Meeting^ December 16^ 1SS7. Present, 27 members.

The death of Dr. M-dclleton Goldsmith (Rutland, Vermont), on November 26, 1887, ret. 70, was announced. This being the evening for the consideration of communica- tions pending for the Magellanic Premium, the Society dis- cussed the claims of one signed " Magellan " on the " Physical Phenomena of Harbor Entrances ; Their Causes and Remedies ; Defects of Present Methods of Improvement," and on being put to a vote it was unanimously resolved that the Society would consider the claims of the said paper. Upon the question then recurring as to whether the said communication was worthy of the proposed premium, a vote was taken and the Society unanimously resolved that the said communication was v/orthy of the premium, and that the Ma- gellanic Premium should be awarded therefor. The sealed letter accompanying the crowned performance was then ordered to be opened, which was done by the Secre- taries, and the name of the author. Prof. Lewis M. Haupt, of the University of Pennsylvania, was announced as the person entitled to the said premium. On motion, the President was authorized to appoint at his leisure a committee of three mem- bers to attend to all the details connected with the preparation of the medal, etc. [The President subsequently appointed Messrs. J. Sergeant Price, R. M. Bache and Henry Phillips, Jr., as such committee.] The Secretaries presented a communication by Rev. Charles W. King, entitled " The Epitapb of M. Verrius Flaccus." Prof. Houston exhibited a Palladium Hair Spring of a non- magnetizable watch and mentioned the experiments he had already made and was making on it. The Finance Committee presented its Annual Report, and the appropriations for the ensuing year were passed. The Committee on Volapiik reported progress, and the re- port was made the special order for the next meeting. This being the regular meeting for balloting-for candidates, a ballot was gone into, and Mr. Samuel Castner, Jr., of Phila- delphia, was declared duly elected a member of the Society.
