ceived from various sources, a number of them from former students 

 of the courses of geology. While the generous gift of the late Prof. 

 E. D. Cope does not strictly concern the department of geology, as 

 defined by the By-Laws, a reference to it cannot be omitted. Prof. 

 Cope's collections are not only a monument to the indomitable en- 

 ergy aud scientific devotion of a master of his specialty, but of the 

 utmost importance to the student of vertebrate paleontology. The 

 collections should be secured for the Academy, to which they have 

 been virtually proffered, and with which the name of the deceased 

 has been most intimately associated. 



Daniel G. Brinton, M. D., Professor of Ethnology and 

 Archaeology, reports that during the spring of 1897, a course of 

 free public lectures was delivered by him in the lecture hall of the 

 Academy on the recent advances in the science of anthropology. 

 The lectures were well attended, and an increased popular interest 

 in this branch was manifest. 



The anthropological collections of the Academy have been ar- 

 ranged in mostly new cases and exposed to public view in a favor- 

 able portion of the recently constructed addition to the Academy 

 building. The number of visitors who give attention to this portion 

 of the collections of the Academy show that it is one in which the 

 general public is much interested. 



Benjamin Sharp, M. D., Professor of Invertebrate Zool-

 of ten and the other of six lectures, upon invertebrate zoology, 

 under the auspices of the Ludwick Institute, and one lecture in the 

 Friday Evening Course on " The Sea and its Influence upon Animal 

 Life." 



The additions to the museum have not been extensive, the most 

 important being the collection of invertebrates made by the Alas- 

 kau and Siberian Expedition. 



Henry A. Pilsbry, Professor in the Department of Mol- 

 lusca, reports that he has delivered two courses of lectures upon 

 Malacology during the year. 



Several reports upon particular groups of mollusks, both recent 

 and fossil, based upon material in the collection of the Academy 

 have been prepared and published in the Proceedings, together with 

 others based upon material sent for investigation from abroad. Pro-
