Estersholm by Mr Sefstrom, and which also exists in Mexico in a brown 

 ore of lead of Zimapan. M. del Rio, Professor in the School of Mines 

 of Mexico, had extracted from that ore a substance, which, to his apprehen- 

 sion, resembled a new metal, to which he gave the name of Erythronium. 

 M. Collet Descotils, to whom he sent a specimen, could not agree in 

 erythronium being a simple substance, and believed he had demonstrated 

 that it was an impure chrome. It would appear that Professor del Ris 

 agi'eed in this opinion, and there was not longer any idea of its being a new 

 metal. But since the discovery of Sefstrom was known to Voller, he, struck 

 with the resemblance which exists between the properties of vanadium and 

 that which the Mexican chemist attributes to his erythronium, has repeated 

 the analysis of the brown ore of lead of Zimapan, and from which he has 

 obtained a simple body, perfectly identical with that of the iron ore of 

 Esterholm. It is worthy of remark, that so rare a metal should have 

 been discovered in two places so far asunder as Scandinavia and Mexico. 



Analysis of the Chalybeate Water of Vicar's Bridge. — This powerfid 

 chalybeate has a specific grav. at 62° F. of 1.04893, being higher than 

 that of any sea water, \vith the exception of the Dead Sea. According to 

 Mr Connell, an imperial gallon contains — 



3941.76 grs.

JBones of Anoplotherium and Palaeotherium in the Lower Fresh Water 

 Formation of the Isle of Wight — Mr S. P. Pratt lately discovered, in the 

 lower and marly beds of the quarries of Binstead, in the Isle of Wight, and 

 which belong to the lower fresh water formation, a tooth of an Anoplothe- 

 rium, and two teeth of the genus Palceotherium, animals characteristic of 

 strata of the same age in the Paris basin. 



These remains were accompanied, not only by several other fragments of 

 the bones of Pachydermata (chiefly in a rolled and injured state,) but also 

 by the jaw of a new species of Buminantia, apparently closely allied to the 

 genus Moschus. From the occurrence of the latter fossil, the author infers 

 that a race of animals existed at this geological epoch, whose habits required 

 that the surface of the earth should have been in a very different state from 

 that which it has been supposed to have presented, in consequence of the 

 frequent discovery of the remains of animals who lived almost entirely in 

 marshes — Ann. of Phil. Jan. 1831. 



Bones of Fossil Tortoises — M. Julien Desjardins has found fossil vertebrae, 

 a pelvis, and bones of the extremities of the tortoise, in the Mauritius ; 

 thus corroborating a discovery made by Dr Guch, of some fragments of 

 bones of this animal. Dr Guch's specimens were found in a hard limestone, 

 from which it was impossible to obtain them entire. M. Desjardins has 

 been more fortunate in meeting with them in a whitish marl, from which 

 he was able to dig them out with his hand. 



The Island Rodrigo also contains fossil bones of tortoises and birds.
