1. Minerals described as new species. 



411. AntiUite. — A name given by C. U. Shepard to a substance be considers to be a 

 hydrated bronzite. It occurs both massive and crystalline, presenting minute coppery 

 laminse, -vritb a fibrous cleavage. H. =3'5^L G. =2 52. Color dark greenish- brown. An 

 Lysis g -e Si 39*30, Mg 3612, Fe 6*70, H 16*79, with traces of Cr, Ca, K=98*91. This 

 composition apf>roaches that of serpentine or deweylite. (Appendix to Catalogue of Meteor- 

 ites. Amherst. Mass., January 1, 1872). 



235. Amblystegite. — G. vom Bath, Pogg. Ann., cxxxviii. 531. 



Orthorhombic : i-l a 7=135 D 50', i-l A 1-3=119" 26', \-% A 1-2=163° 47', i I A \ *= 

 98 ; §V . Cleavage not observed. Hardness nearly equal to quartz. G. =3*454. Lustre 

 adamantine-vitreous. Color brown to reddish-brown. Streak greenish-gray. Translucent.

Only half a gram was available for analysis, and the state of oxydation of the iron was 

 not determined. B. B. difficultly fusible without intumescence to a black glass. Not de- 

 composed by muriatic acid. Found at Lake Laach. Amblystegite is closely related to 

 hypersthenic in form and chemical composition. V. v. Lang has recently discovered crys- 

 tals of hypersthenite in the meteorite of Breitenbach which give the same planes as ambly- 

 stegite. and vom Rath now announces (Jahrb. Min., 1871, 642) the identity of his supposed 

 new species with hypersthenite. 



799 B. Ambhosine. C. U. S7iepard, Rural Carolinian, i. p. 311. 



In rounded masses. Color yellowish to clove-brown. Fracture conchoidal. Lustre, 

 resinous. Becomes electric on friction. Melts at about 460 Q F. to,a clear yellowish liquid ; 

 softens at a lower temperature. Gives off "succinic acid " before melting ; on fusion gives an 

 agreeable balsam odor, unlike that from the resins of ordinary pines, and a dark brown non- 

 volatile fluid remains as long as the melting heat is kept up. Combustible, leaves no ash. 

 Soluble for the most part in oil of turpentine, alcohol, ether, and chloroform, as also in pot- 

 ash. Found in the phosphatic beds near Charleston, S. C, having originated in the eocene 

 formation. 



Andeewsite. iV. 8. Maskelyne, Chem. News, xxiv. 99. 



In globular disks with radiated structure resembling wavellite. G. =3 "475. Color bluish- 

 green. Composition, a hydrous phosphate of iron and copper. An average of four deter- 

 minations gave 10-82 per cent, of copper; and according to Maskelyne ..the analyses (not 

 given in the article quoted) " justify the formula 3 (¥e P\ 3?e H 3 ) + Cu 3 P, in which, how- 

 ever, a portion of the ferric phosphate is replaced by ferrous phosphate, as in vivianite is 

 frequently the case with the two phosphates." 



Occurs in Cornwall on a quartzose veinstone associated with limonite and gothite, and 

 interpenetrated with a mineral resembling, if not identical with, dufrenite. Requires further 

 description. 



71 A. Arsenical cobalt. Under the title EinfacJi-arsenilc-cobalt, Kenngott calls attention 

 to a mineral which appears to be hexagonally crystallized arsenid of cobalt, occurring with 

 barite and quartz at Bieber (Jahrb. Min., 1869, 754).
