table substances. Germs, &c. were destroyed by heat (212° F.), and 

 the introduction of matter was prevented by other contrivances, 

 while the exposure to atmospheric air, light, and heat was continued. 

 Three months produced no living creature ; but a few days after the 

 inclosed matter had been exposed, many Vibriones and Monades, with 

 " larger polygastric infusoria," were noticed. — V. On the Sivathe- 

 rium, a new fossil ruminant genus found in tertiary strata in the 

 Valley of the Markanda, in the Sivalik branch of the Sub-Himalayan 

 Mountains, contains only remarks from sources already published. — 

 VI. On the colossal fossil Mammiferous Quadruped named Dinothe- 

 rium giganteum. Extracted from Buckland's Bridgewater Treatise ; 

 Blainville and M. Rauss, in the ' Comptes Rendus.' — VII. Account 

 of the Skull of a Fossil quadrumanous Animal, found in the tertiary 

 rocks of the Sub-Himalayan hills, near the Sutlej. Extract from 

 Journal of the Asiatic Society. 



Botany. 

 I. On the condition of Fossil Plants, and on the process of Petri- 

 faction. By H. R. Goppert. Translated from PoggendorfFs Anna- 

 len. — II. Remarks on the Origin of Amber. By the same author, 

 and from the same source. The author here considers " that amber 

 is nothing else than an indurated resin derived from various trees of 

 the family of the Conifera ; which resin is found in a like condition 

 in all zones, because its usual original depositories, viz. beds of brown 

 coal, have been found almost everywhere under similar circum- 

 stances." 



October. Zoology. 



In this number there is little relating to zoology or botany. The 

 only paper which comes under our range is, I. Analysis of the Scales of 

 the fossil Gavial of Caen in Normandy. By A. Connel, Esq., F.R.S.E. 

 In the result of his analysis Mr. Connel considers that " these scales 

 were originally of the nature of bone, and in all probability analo- 

 gous to the osseous bones of fishes ;" and he suggests the more de- 

 tailed inquiry whether the coverings of the extinct and recent Sau- 

 rians are identical. In the ' Scientific Intelligence ' there is a notice 

 by M. Baer, of the Prussian and Polish aurochs being found in the 

 Caucasus. No botanical papers in this number.
