Dr. Brewer informed the Society that a second list of 

 specimens collected in California, had been received from 

 Mr. E. Samuels ; and that those catalogued in the first list 

 sent by Mr. Samuels, are now in Washington, on their way

The President remarked, that the Society had recently 

 lost by death two of its oldest and most valued mem-

 accurate, practical knowledge than would have been sup- 

 posed from his modest and retiring manners, and exhibited 

 a great natural sagacity in those departments of science 

 which he loved. Science had lost in Zadock Thompson 

 a devoted student.

 son of Mr. Barnabas Thompson, whose father was one of the

 Thompson showed that strong propensity for observing facts in 

 Natural Science, and for mathematical applications, which made 

 the results of his studies so reliable. Obliged to struggle against 

 pecuniary difficulties, he made steady progress in science, and
