sion of Mr. Edward Renwick, Columbia College, one of which proves 

 to be the Catopterus gracilis of Redfield,* and the other a strongly- 

 marked species of Palczonisciis, also found at Middletown. It ap- 

 pears, therefore, that most of the fossil fishes found in the Connecti- 

 cut sandstone, prove to be identical with those which have been found 

 in New Jersey. This discovery promises to be of some importance 

 in .settling the geological relations of these sandstone formations. R. 



II. VolbortJiite, a vew Mineral. — At the session on the 16th of 

 March, 1838, of the St. Petersburgh Imperial Academy of Sciences, a 

 notice by Dr. A. Volborth was presented on a new mineral containing 

 vanadium. 



The vanadic acid has hitherto been found only in Mexico, Scot- 

 land, and the eastern part of Russia, and in combination with lead in 

 the form of vanadiate of lead. This new mineral, called Volborthite, 

 was communicated to the author by Dr. Ranch, who had purchased 

 it with other minerals, of M. de Solomirsky, from which he presumed 

 that it came from the mines of Solomirsky, (Syssersk?). It is a van- 

 adiate of copper, and consists of a mass of minute conglobated crys- 

 tals, of an olive color, and which are so small that their crystallo- 

 graphic characters cannot be well determined. Its fragments are 

 translucid — transparent, with a crystalline lustre by reflected light. 

 It scratches calcareous spar; streak, pale yellowish-green and nearly 

 yellow : gravity, =3.55. It undoubtedly occurs in great abundance 

 in the copper mines, between Miask and Katharinenburgh. Its gangue 

 is Beresite. — Vlnstitut, {Paris,) Dec. 27, 1838. 



12. Reclamation of M. A. Warder, in a letter to Prof. Silliman, dated 

 Springfield, ( Ohio,) March 8, 1839. — Much as I regret to occupy your val- 

 uable time, with any subject not strictly scientific, still, since the inser- 

 tion in the last number of your valuable and highly interesting Journal, 

 of J. G. Anthony's letter, with its implied censure, calculated to convey a 

 false impression, I feel it due to my brother. Dr. J. A. Warder, to state, 

 that the fossil trilobite described by him, had been in my possession many 

 months, before I had an opportunity of presenting it to him to be de- 

 scribed and named. T am aware that the priority of discovery, is of little 

 consequence to the cause of science, and was submitted by Dr. Warder, 

 to the decision of those, who were disinterested, in the very letter, of the 

 July number, 1838, of which J. G. Anthony so unjustly complains ; and 

 I should not now trouble you, if I did not fear that the censure will be 

 -read without a reference to the letter from Dr. Warder.
