540 PROCEEDINGS OF THE ACADEMY OP [1899. 



Johnson has continued his work on the collection, completing the 

 arrangement of the Eocene material. 



Mr, Theodore D. Rand, special Curator, has spent much time 

 in the arrangement and cataloguing of the William S. Vaux 

 collection of minerals. These services are more specifically set forth 

 in the reports of the several sections. Important service has also 

 been rendered by Mr. Witmer Stone, assistant to the Curators, in 

 all departments of the museum, especially in that of Ornithology. 

 Assistance in the arrangement and care of the collections has also 

 been received from the students of the Jessup Fund. Mr. H. W. 

 Fowler has made a systematic study of many of the families of 

 fishes in the collection, and identified a large number of unlabel - 

 led specimens. Mr. E. G. Vanatta has done excellent work on 

 the mollusca and other invertebrates ; Mr. S. H, Hamilton on the 

 minerals and Mr. A. F. Satterthwait on the insects. 



The additions to the collections during the year have been 

 important. 



The valuable Hoopes collection of North American Birds renders 

 the Academy's material in this department equal to any in the 

 world. A series of American birds presented by Dr. S. W. 

 Woodhouse contains much of historic interest. 



The collection of local fishes I'eceived from Mr. H. W. Fowler, 

 comprising several thousands of specimens, is a valuable accession, 

 containing in large series many forms previouslv but poorly repre- 

 sented in the museum. 



The series of painted casts of American snakes presented by Mr. 

 Clarence B. Moore is equal to any other such representation of 

 Ophidia in this country. 



The Zoological Society of Philadelphia has presented many 

 valuable specimens, the mounting of which by the Academy's 

 preparator illustrates strikingly the advance in taxidermic art, 

 Avhen compared with the objects formerly composing the cabinets. 



Specimens have been loaned during the year to Lewis Woolman, 

 F. L. Scribner, G. A. Boulenger, J. M. Coulter, G. S. Miller, 

 H. M. Smith, W. H. Osgood, T. Waylaud Vaughau, Robert 

 Ridgway, H. C. Oberholser, J. Dwight, Jr., R. H. Howe and C. 

 L, Lochman. 



Henry C. Chapman,
