formerly remarked Ihey indicated at least two species of rhino- 

 ceros. One of these was tliouijht to be the same as the K. ocd- 

 dciiliilis ; the other was suspected to be the same as the Californian 

 species, R. hesferius. Some additional specimens indicate the 

 second species to have been intermediate in size to that last 

 named and the R. crassus of the Niobrara river. One of the 

 specimens from Bridge Creek, consisting of a mutilated upper 

 jaw fragment, with portions of the fangs uf the true molars, 

 shows these to have occupied the space of about 5 inches. An 

 isolated tooth from Alkali Flat, apparently a last upper premolar, 

 probably belongs to the same animal. From the outer part of 

 its cxoNW three folds project into the bottom of the medi.an 

 valley. The tooth measures i inch and 10 lines wide. The 

 species may be named Rhinoceros pacificus. Another fossil 

 specimen, labelled " Crooked River," consists of an isolated ver- 

 tebral plate of a large turtle, apparently the eighth bone of tlie 

 series. It has the same shape as in S/r/c/vs itiolirarensii, but 

 is proportionately much shorter in relation with its breadtli. It 

 measures 2 inches wide, i inch 7 lines long, and 7 lines thick. 

 The specimen probably indicates an undescribed species, which 

 may be named StyU/iiys on-i^onensis. Two additional fossils are 

 brain casts, probably of Orcodoii supcrbus. The cerebral hemi- 

 spheres are 10 inches S lines long, and together about z\ inches 

 broad. 



Paris 



Academy of Sciences, June 17. — A note by M. E. Com- 

 bescure on a point in the theory of surfaces was presented by 

 M. Chasles. — M. E. Roger read a third memoir on the theory of 

 capillary plienomena. — Father Secchi forwarded a reply to the 

 observations recently presented by M. Respighi in opposition to 

 his remarks on some peculiarities in the constitution of the sun. 

 — M. A. Genocchi read a paper on the intensity of the heat of 

 the sun in polar regions, in which he discussed the calculation of 

 the annual mean heat' of the sun within the polar circles. — M. 

 C. Martins communicated a note on the stormy nature and un- 

 equal distribution ol the rains on the surface of the department 

 of Hcrault. — M. A. Berigny forwarded a note describing the 

 effects produced by the striking of a house by lightning at Ver- 

 sailles on the night of June 6. — M. Lartigue presented an expla- 

 nation of the mistral. — M. H. Sainte-CIaire DeviUe presented a 

 note by M. Laurence on a compound of oxide of tin with anhy- 

 drous acetic acid, produced by heating the two substances together 

 in a sealed tube to 302" F. Upon this paper M. Elie de I3eau- 

 mont made some remarks, in which he put forward the notion 

 that in the early ages of the world nature may have employed a 

 chemistry different from that which we now see in action in 

 volcanoes and in atmospheric phenomena. — M. Sainte-CIaire 

 Deville also presented a note by M. G. Saillard on a new 

 phosphoplatinic derivative of toluidine obtained by heathig an 

 alcoholic solution of Schutzenberger's ether Ph (C" H'O) ^Pt CI", 

 with an excess of crystallised toluidine. — M. Blanchard com- 

 municated a note by M. C. Dareste on the natural affinities of 

 the fishes of the family Balistida;, which he regards as most nearly 

 allied to the Teuthyidiv. — M. Garrigou presented farther obser- 

 vations on the constitution of the Pyrenees in reply to a note by 

 M. Leymerie, and in support of his previous remarks on tlie 

 same subject ; and M. A. Brongniart communicated a note by M. 

 G. de Saporta on a revision of the fossil flora of the gypseous 

 deposits of Aix. 



June 24. — M. O. Bonnet communicated a note by M. A. 

 Ribaucour on the theory of lines of curvature. — M. Delaunay 

 presented a note by M. Bresse on the determination of the tra- 

 jectory of a point for which a certain integral is the minimum. 

 — M. J. IVIorin read a notice of a new voltaic battery with con- 

 tinuous action, acting by sulphate of copper. This consists of a 

 hollow cylinder of copper, in the centre of which is the cylinder 

 of zinc, he two being separated by a cylinJerof filtering paper, and 

 the space betwe;n tlie copper and paper being filled with grit, and 

 that between the paper and the zinc with flowers of sulphur. Bat- 

 teries of this construction have been in operation for twenty 

 months without being replenished. — M. Piarron de Mondesir 

 forwarded a note on the theoretical value of the relation between 

 the two specific heats of permanent gases. — M. de .Saint- Vcnant 

 presented a note by M. J. Boussinesij on the calculation of the 

 velocity of light in bodies in motion. — M. Del.aunay communi- 

 cated a paper by M. F. Tisserand on movements relative to the 

 surface of the earth. — A note was read by M. T. Schloesing on 

 the solution of carbonate of lime by carbonic acid, containing 

 the results of series of experiments made by the author on this 

 important subject. — A note by MM. Girard and De Laire on the 



manufacture of aniline colours, was re%d. — M P. Champion 

 presented a note on som; compjundi of p iratfii, in w'licii h; 

 described an acid, paraffnic acid, with the formal iC-' H-' NO'" 

 derived from paraffin by the action of nitrosulpliur.c acid, anl 

 noticed the action of chlorine and bromine upjn paraffin. — ■ 

 M. Milne-Edwards presented a note by M. Fischer on the 

 geographical distribution of the podophthalmous Crustacea of 

 the IJay of Biscay, in which the author compared this part of 

 the f.iuna of the Bay with that of the British coast on the on> 

 hand, and that of the Mediterranean on the other. — M. C. Ber- 

 nard presented a further note by M. Ore on M. Liebreic'i's 

 opinion that strychnine is to be regarded as an antidote to chloral ; 

 and a p.aper by M. Bremond containing an account of some ex- 

 periments on cutaneous absorption. — M.Duch.artre communicated 

 a note by M. Prillieux on the disease of the peach trei known in 

 France under the name of cloqiie, which the author ascribes to 

 the action of a parasitic fungus, described by Tulasne under the 

 name of Taplirina dcfoniians. — -M. Daubrce presented an ex- 

 amination of the rock-masses of native iron, discovered by Prof. 

 Nordenskjold in Greenland, of one of which he gives an analysis. 

 — M. Daubrcie presented a report on a recent memoir by M. 

 Delesse on the deformations which the strata of France have 

 undergone. — M. do Quatrefagcs communicated an interesting 

 paper by M. J. de Biye, "On the Prehistoric Caverns of the 

 Marne, belonging to the Neolithic period;" and a second note
