 North America, with those of Europe," Paris, 1847, p. 43. Translated from the

" The collection of M. John Gebhard junior is one of the richest for 

 " the series of rocks and fossils, which constitute the hills of the Helderberg 

 *' around Schoharie," &c. 



From Prof. Hall's Geology of the Fourth District, p. 145. 

 " Upper Pentamerus Limestone : Mr. Gebhard junior, of Scho- 

 " harie, has clearly demonstrated, that hy its peculiar assemblage of fossils, 

 *' it is distinguished from any other rock. The thorough practical acquain- 

 " tance of Mr. GtEBHARD with all the rocks of this part of the system, and 

 ■*' his nice discrimination of their fossil contents, renders his opinion decisive 

 *' in such distinctions."
