4. Fifteenth Annual Report of the Regents of the University of the 

 State of New York on the condition of the State Cabinet of Natural 

 History, dec, made to the Legislature April 12, 1862 ; 8vo, pp. 170. 

 Albany: C. Van lienthuysen, 1862.— This Report contains the continua- 

 tion of Prof. Hall's Palseontological researches. ^The larger part of the 

 memoir has been already noticed briefly in former issues of this Journal, 

 vol. xxxii, 430. Nov., 1861, and in this volume, p. 282. It is enriched 

 by numerous figures in the text and by eleven plates of fossils, two of 

 them on stone. One of the latter is a reproduction of a plate of Mr. 

 Conrad's to vindicate himself and Mr. C. from the criticisms made by 

 Mr. Billings of the Canadian Survey, upon the genera Cypricardites and 

 Modiolopsis. 



The last page of the report contains a 

 Curator of the State Cabinet, announcing an 

 by that gentleman on the age of the " Catskill group." The same intorma- 

 tion has been communicated to us in a letter from Col. Jewett, but we 

 copy from the official document as follows : 



" Albany, September 20, 1862. 



Dr. S. B. WooLWORTH, Secretary of Regents, &c.— Sir:- Agreea^}<' 

 to your directions, I went to Delaware county, to collect fossils trora the 

 Catskill group, or Old Red Sandstone. 



At Franklin I found Mr. J. M. Way, a gentleman who for years has 

 been examining the rock and collecting the fossils; and although he is 



lacquainted with any other localities, and has never seen a collection 



of fossils, he has succeeded in investigating the whole 



5 able 



miles southwest of the village of Franklin, more thar 

 ness. The base is a brick red shale, with oceasioi 

 sandstone, about 400 feet. On this is about fifty fee 

 on which lies a stratum of gray sandstone, with teeth 

 and fossils of the Chemung group. Seventy feet '" 

 this fossiliferous stratum; when another thin band 



—•' Mie same formation, continues with alternate ^ ^ . 



and fossils to the top of the hill, where the Chemung tossils 



of tossils, with gravel 

 shale and gray sand- 

 ..!« ciuu ii.ssu» lu Lu« t^p ^. tu« u..., ,...<=.. .-e Chemung tossils are 

 )re numerous. Spirifers, Rhynconellas, Pectens and Athyres are founa 

 all the strata of the upper three hundred feet, and the whole formatio 



is undoubtedly Chemung. 



I examined other localities with the same remit. ., 



Mr. Way has examined the rock as far as Deposite (twenty-five mi e^ 



southwest), with great care, and finds the same formation. He has 



collected the same fossils at Delhi, seventeen miles southwest. 



From my investigations, I believe that there is no Old Red Sandston 



[Catskill formation] in this State. * * * 



Respectfully, 4c.
