belonging to me, now in his possession, in my opinion, to complete 

 the third volume of the Palaeontology. I have no doubt that 

 there are at least eight hundred different species of New- York 

 fossils in the collection^ and of nearly all of which there are 

 numbers of duplicates. 



I propose to sell my whole collection of fossils for the sum of 

 two thousand dollars : one thousand to be paid on their delivery 

 at such place as the Eegents shall direct ; and the residue in one 

 or two years, as shall best suit the convenience of the Eegents. 



I claim the kind indulgence of the Eegents, in presenting for 

 their consideration the following notices ; which, as they were 

 written several years ago, are undoubtedly impartial opinions of 

 their authors, although my collection has increased one half in 

 number since those opinions were written. 



Extract from the Third Annual Eeport of T. A. Conrad, on the Palaeontological 

 Department of the Survey, for the year 1840, p.. 203. 



" One of the finest geological sections in the whole range of the Silurian 

 " System occurs at Schoharie, where, fortunately, the organic remains have 

 " been collected in large numbers by my friend John GtEBHARD junior, whose 

 " zeal is worthy of all praise. Through him, I have obtained rare and 

 " valuable specimens for the use of the survey, and stUl more valuable in^ 

 " formation regarding the stratigraphical position of some of them." 



From Mr. Hall's first volume of the Palaeontology, printed in 1843, p. 12, preface. 



" Mr. John G-ebhard junior, of Schoharie, has allowed me the free use 

 *' of his valuable cabinet, which has furnished several fine specimens for the 

 " present volume, and will be of the most essential importance in illustration 

 " of the middle and higher groups." 



From Prof. Mather's Report on the First Geological District, printed in 1843, 



p. 347. 



Speaking of the Pentamerus Limestone, Prof. Mather says : "It is 

 *' well exposed to view near the village of Schoharie, where its fossils have 

 " been carefully examined by John GtEBHARD junior and others for many 

 " years. This gentleman has made a more perfect collection of fossils of 

 " this and of other members of the Helderberg division of rocks, than any 

 '* other person."
