spersed in irregular masses through the stone, and as near as I could 

 judge without special investigation, was equivalent to about two pounds 

 troy, perhaps a little more. Other specimens much larger, are said to 

 have been found, and one of 20 pounds weight pure, near the Stanis- 

 laus ; but these I have not seen. 



2. Geographical Survey of Tennessee. — The geographical survey of 

 Tennessee, under Dr. Troost, is still in progress, and is bringing to 

 light many valuable additions to science, besides developing the vari- 

 ous resources of the state. Prof. Troost is well known for his learn- 



I 



ng, his skill, and his enthusiasm in his investigations, and it is greatly 

 to the honor of Tennessee, that such a savant is appreciated and his 

 talents called into action. In a recent communication from Dr. Troost, 

 he mentions that the number of i he new genera and species of Cri- 

 noidea which occur in the state of Tennessee is really surprising. 

 His Geological Report now before the legislature of the state of Ten- 

 nessee, contains a monograph of Crinoidea of that state, in which 16 

 new genera and 88 new species are described, illustrated by 220 fig- 

 ures ; this number not only surpasses that of those discovered in the 

 other states of the Union, but perhaps is equal to those that have been 

 found over the whole of Europe. 



The list which he communicates is as follows :
