Dr. A. A. Gould read a letter from Prof. Hubbard of 

 Dartmouth College, giving an account of a fish which was 

 seen to fall to the earth, during a sudden squall of wind 

 and rain, in a town in Vermont. Dr. Gould thought the 

 fact interesting, as corroborating several instances of the 

 same kind which had previously been recorded, some of 

 which had come to his own knowledge. 



Dr. Gould also stated that a letter had been sent to him 

 through Prof. Lovering by Mr. George S. Blackie, written 

 by Prof. Gregory of Edinburgh to the late Prof. Bailey. 

 Dr. Gould read several passages of general interest 

 regarding certain observations made by Prof. Gregory 

 on the Diatomaceous Exuviae of the Post-Tertiary sand 

 at Glenshira, near Inverary, the greater part of the letter 

 being devoted to a close criticism on certain new forms. 

 Several prepared specimens, and a number of pamphlets 

 on the subject, were laid on the table, to be added to the 

 collection of Prof. Bailey. 



On motion of Dr. Gould, it was voted that the receipt 

 of the letter and specimens be acknowledged with thanks 

 to Prof. Gregory. 



Dr. Kneeland presented a large number of specimens, 

 collected by himself, illustrating the different forms in 

 which the copper occurs, and the various rocks with 

 which it is associated, in the Lake Superior district of 

 Keweenaw Point. 



All the copper, with the exception of a small amount of car- 

 bonate near the surface, which he liad seen over this extensive
