Dr. S. B. WOOLWORTH, 



Secretary of the Regents : 



Sir — Within the year I have collected and placed in the State 

 Cabinet, the following fossils : 



From the Oneida Conglomerate, New Hartford — Orthophy- 

 cus Harlani (Fucoids Harlani of Yanuxem). 



This fossil has been regarded as being found only in the Me- 

 dina sandstone. Mr. Yanuxem in his description says : *' In 

 this rock we find the Fucoids Harlani, and in no other of the 

 whole of the New York system has it been seen ; it appears 

 therefore to be one of those fossils which are limited to the 

 rock, and which affords us a positive character whereby to re- 

 cognize the rock, or its position in the great series.'' 



The fossil is found within two feet of the base of the Conglo- 

 merate, which rests on the slate of the Hudson River group. 

 The thickness of the Conglomerate at New Hartford is near 

 twenty feet, and it must be the sole representative of the grey 

 sandstone of Oswego and the Medina sandstone, which in the 

 western part of the State is at least five hundred feet thick. 



Mr. Yanuxem says : " The Conglomerate must rest on the 

 red sandstone in Cayuga County, the two rocks being near each 

 other, and no intermediate there existing, but the space between 

 is covered so as to conceal the contact. Such also would be its 

 position in Oswego, were the whole of the alluvial of the north 

 border of the lake removed, and the Conglomerate left in its 

 original position." 



By this it seems that he did not see the junction of the two 

 rocks, and hence the error.
