560 PROCEEDINGS OF THE ACADEMY OF [Dec, 



No detailed mention need be made of the various verbal com- 

 munications; it is sufficient to state that it is the custom of each 

 member to provide at each meeting material illustrative of his own 

 particular studies. 



Mr. T. Chalkley Palmer continues his investigations of the move-

 demonstrations of microscopical technique have been of special 

 interest.

During the Centenary of the Academy a large part of the collection 

 of exotic Lepicloptera was placed on exhibition in the room formerly 

 occupied by the library and attracted much attention and interest. 

 During the year 6,858 specimens have been received, either by gift, 

 exchange or purchase, and a considerable proportion of these have 

 been mounted and incorporated into the collections. 



Twenty-four Brock tins and one hundred large glass-covered cases 

 have been purchased by the Academy. It seems to be the opinion 

 of those persons best qualified to judge, that this style of box is the 

 best so far devised, and it is considered desirable to adopt it for all 

 the orders of insects. After the collections were transferred to the
