The list of Committees on obituary notices was read. 



On motion of Dr. Dunglison, Dr. Wood was appointed to 

 prepare an obituary notice of Dr. Beasley. 



Dr. Patterson exhibited to the Society a diaTnond, which he 

 had this day received, enclosed in a letter from Mr. James F. 

 Cooper, Superintendent of the Branch Mint at Dahlonega. 



It was found in Hall County, in the northern part of Georgia, in 

 conducting the process of washing for gold. 



Its weight is 6.8 grains ; its specific gravity 3.54. It is a perfect 

 crystal, in the form of a rhomboidal dodecahedron, with the rounded 

 faces characteristic of this gem. 



Its general outline is oval, somewhat flattened, or having, in the 

 language of the lapidary, a good spread. 



It had been exhibited to Mr. Isaac Philips, of Philadelphia, a gen- 

 tleman thoroughly acquainted with the qualities and varieties of dia- 

 monds, and he pronounced it to be very white, and of the first water. 

 He said that it bore a strong resemblance to those obtained from 

 Borneo. 



Mr. Cooper states, in his letter to Dr. Patterson, that two similar 

 specimens had been found in the same locahty. A diamond had also 

 been found in the gold region of North Carolina some years ago, and 

 was in the possession of Mr. Clemson.
