merouslsomorphy, or, more briefly, Heteromery. He takes in order the physical 

 and the chemical properties of heteromerous Crystals, a nomenclature of their 

 composition, and a systematic arrangement of Minerals. The Heteromerous 

 system differs from the Chemical, in regarding most minerals not as primitive 

 Chemical combinations, but as Molecular aggregates. The two agree in com- 

 mencing with the electro-negative constituents as the ground of classification. 

 According to this principle, the Minerals, with similar or Isomorphous elements, 

 are reduced to eleven classes. Each class is subdivided into seven orders, 

 corresponding to the different systems of crystals. A table is added of the 

 atomic weights of ninety-three different bodies. (Basilewsky) Ichthyography 

 of Northern China ; with nine chromo-lithegraphic plates, from drawings after the 

 life, by a native Chinese artist — p. 215 263. Sixty fishes of Northern China are 

 described, of which four only are referred to as known species. The following 

 new genera of Cyprinidee are proposed : Carassius, with three species, new ; Culler, 

 type, Cyprinus cultratus L., six species, new ; Abramis, two species, new ; and of 

 Murseuidse Apterigia, three species, new. An extract is given from a Chinese 

 work on the fishes used in medicine, which are divided into two orders, those 

 with scales and those without. The Cetacea, Crustacea, and Mollusca are 

 included among the latter. The plates, whioh exhibit twenty-nine species, are 

 successful specimens of art. (Eversmann) Brief Observations on the occurrence 

 and diffusion of some Mammalia and Birds in the region between the Volga and 

 Ural, and in the Kirghis Steppes — p. 265-281. An appendix to the previous 

 essays by the author, on the same subject, chiefly in the Bulletin of the Society. 

 (Eichwald) On the Natural History of the Caspian ; with a plate — p. 283-323. 

 While the shores and bed of this sea are almost an accumulation of empty shells, 

 the living Mollusca are scarce, and limited to a few genera and species. Only 

 where the great rivers, which empty themselves into the Caspian, reduce the pro- 

 portion of salt in its waters, certain shells, chiefly related to the Pholadomya, as 

 Adacnce, &c, are more abundant. The existing species are also in general of 

 small size, presenting a contrast to the great bulk of many in the fossil deposits. 

 Twelve species are more particularly noticed and described ; of these, as new, 

 Palndina spica, Dreisena caspia, Pholas ustuertensis, Cardium ornatum, Spirorbis 

 nodulus.
