A collection of sections of the trunks of native forest trees, com¬ 
prising almost all the species found in the Middle States, was pre¬ 
sented by Mr. C. H. Jennings. 
Through the courtesy of the New York Botanical Garden, Mr. 
Stewardson Brown was enabled to accompany Dr. N. L. Britton, 
Director of the Garden, on an expedition to Bermuda, where he 
made collections which added materially to the Academy’s series 
of the plants of the island. 
Through the liberality of Mr. Morgan Hebard, Mr. Rehn was 
enabled to spend the summer months in Florida and Texas, where 
together they made large and valuable collections of Orthoptera, 
half of which becomes the property of the Academy. 
In addition to the work described in the special reports appended, 
Dr. J. Percy Moore has continued his investigation of the annelids 
obtained in the Pacific Ocean by the United States Bureau of 
Fisheries. He has identified and named many parasites and other 
worms submitted to him for identification. 
Mr. Henry W. Fowler continues in charge of the fishes and has 
also identified recent accessions of collections of reptiles and batra- 
chians. He has made a study of the catostomoid fishes in the gen¬ 
eral collection and prepared a report on the fishes of the Chincoteague 
region, Virginia. 
The archaeological collection is still under the care of Miss H. N. 
Wardle, who has identified and arranged the new specimens. A com¬ 
prehensive catalogue of the department is in course of preparation. 
The Curators are again under obligation to Messrs. S. S. YanPelt 
and Bayard Long for their continued work on the local collection 
of plants; to Mr. Morgan Hebard for the mounting of many entomo¬ 
logical specimens, and to Dr. Amos P. Brown for the identification 
of several collections of invertebrate fossils forming part of the Isaac 
Lea Collection. This collection has for many years been under the 
care of the Rev. Leander T. Chamberlin, through whose generosity 
it has increased in extent and value from year to year. It is to be 
regretted that Dr. Chamberlin’s ill health has compelled him to resign 
his honorary curatorship. The position has been filled by the ap¬ 
pointment of Mr. Joseph Willcox. 
Numerous local field trips have been taken by members of the 
museum staff, yielding valuable additions to the study series of 
fishes, reptiles, insects, mollusks, and plants. 
One hundred and four storage cases and two hundred insect boxes 
have been purchased since our last report.
