The following is appended to this Report, as the last sheets 

 are passing through the press. 



A few weeks since, an interesting collection of teeth and plates 

 of fishes, supposed to be from the Old Red Sandstone of Delaware 

 county, was received at the Geological Rooms. The Curator was 

 directed to visit the locality, for the purpose of enlarging the col- 

 lection. The following is his report. 



Albany, September 20, 1862. 

 DR. S. B. WOOLWORTH, Secretary of Regents, 8rc. 

 SIR : 



Agreeable to jonr directions, I went to Delaware county, to collect 

 fossils from 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 

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

 of fossils, he has succeeded in investigating the whole strata of the 

 neighborhood and collecting many fossils. With his assistance, I was 

 able to make a section from the Oleout creek to the top of a hill about 

 three miles southwest of the village of Franklin, more than 800 feet in 

 thickness. The base is a brick red shale, with occasional red argillaceous 

 sandstone, about 400 feet. On this is about fifty feet of greenish shale; 

 on which lies a stratum of gray sandstone, with teeth and plates of fishes, 

 and fossils of the Chemwig group. Seventy feet of green shale lies on 

 this fossiliferous stratum; when another thin band of fossils, with gravel 

 and the same formation, continues with alternate shale and gray sand- 

 stone and fossils to the top of the hill, where the Chemung fossils are 

 more numerous. Spirifers, Rhynchon-ellas, Pectens and Athyres are found 

 in all the strata of the upper three hundred feet, and the whole formation 

 is undoubtedly Chemung. 



I examined other localities with the same result. 



Mr. Way has examined the rock as far as Deposite (twent3^-five miles 

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

 collected the same fossils at Delhi, seventeen miles southwest. 



From my investigation, I believe there is no Old Red Sandstone in this 

 State. I found no forms among the fish remains like those of the Old Red 

 Sandstone of Great Britain, but we have plates far larger than those 

 found there. 



The Teeth closely resemble those described by Dr. Newberry, from the 

 Corniferous rocks of Ohio and New- York. 



Respectfully your obedient servant, 



E. JEWETT.
