Davis, to be felt to the depth of perhaps ten fathoms. In shel- 

 tered harbors, such as Massachusetts Bay affords, species which 

 on the Shoals are compelled to live at the bottom of the trenches, 

 can find protection at the depth of a few feet. The fact that 

 specimens obtained from the deepest water on the Shoals are 

 entirely covered with delicate corals, proves the entire quietness 

 of the water. 



Dr. Bacon exhibited the specimen of Quartz crystals 

 having on their surfaces dendritic oxide of manganese, 

 which he had mentioned at the last meeting. He also 

 announced the donation of ^bout one hundred and twenty 

 minerals from Messrs J. E. and E. C. Cabot ; also, a third 

 instalment of minerals from Mr. Alger, making in all nearly 

 two hundred specimens selected from his cabinet. 



Dr. Bacon likewise presented in the name of Mr. C. J. 

 F. Binney, a curious specimen, consisting of silver dollars 

 and a grape shot, incrusted with a calcareous deposit. It 

 was taken from the wreck of the Spanish Frigate San 

 Pedro, which was lost forty or fifty years ago, in the Carib- 

 bean Sea. 



Dr. Cabot exhibited to the Society fifty-six birds, ready 

 to be put into the cases. Most of them were from Mexico, 

 and new to the Society's collection. The remainder were 

 from Mr. Gassett's donation. 



A fine specimen of Coral, from Bermuda, presented by 

 Mr. T. G. Appleton, was laid on the table. The thanks 

 of the Society were voted for the donation. 



Messrs. F. Freeman, John K. Manley, and E. W. Dana, 

 all of Boston, were elected members. 



Dr. Leo Lesquereux, of Columbus, Ohio, was elected 

 Corresponding Member.
