Dr. Le Conte announced the decease of A. L. Crelle, of Ber- 

 lin, a member of the Society, who died in 1856. 



Dr. Le Conte exhibited a piece of silver, said to have been 

 brought from China, which has the form of a flattened cylinder, 

 bent until the ends meet, and having peculiar marks stamped 

 upon it, one of which appears to be in Chinese characters. 



Mr. Justice presented for inspection sundry substances con- 

 sisting of paraffine, lubricating oil, burning oil, naphtha and 

 benzole, all produced from the cannel coal of western Virgiria, 

 and now being extensively manufactured by the Union Coal 

 and Oil Company at their works in Maysville, Kentucky. The 

 coal is mined on the Kanawha river in Virginia, and is sent to 

 Maysville, where the Company is now constructing works of 

 a caj)acity to produce 3000 gallons per day. This coal yields 

 from each ton about an average of 55 gallons of crude oil, from 

 two to three gallons of benzole, and the same quantity of naph- 

 tha; also nearly 18 j)outids of pure parafline. The burning oil 

 loses nearly one-thii-d in the ])urifying process. 



Prof. Crcsson was excused from serving on the committee 

 appointed in relation to the proposed Arctic explorations of 

 Dr. I. L Hayes, and the presiding officer was authorized to fill 

 the vacancy by the appointment of another member.
