Five new plate-glass and mahogany cases have been placed in 
the Museum during the year, one large case for birds and two for 
mammals, while Mr. Clarence B. Moore lias added two for the 
accommodation of the archieological material obtained by him in 
northwestern Florida. A number of moth-proof storage cases of 
various kinds have been provided for the rapidly increasing study 
series of birds, mammals and insects. 
The Museum staff was further increased at the beginning of the 
year by securiug the services of Dr. J. Percy Moore and Mr. C. 
W. Johnson as assistants to the Curators. Dr. Moore has taken 
charge of the Helminthological collection and has identified and 
catalogued all of the material in the Museum. During the sum- 
mer, when on leave of absence at Woods Hole, he made valuable 
collections in this department for the Academy. 
Mr. Johnson, besides the care of the Isaac Lea Collection of 
Eocene Mollusca, which he has continued as heretofore, has been 
able to rearrange, identify and label the entire series of American 
Cretaceous invertebrates. The types identified number upward of 
400. The additions to the Lea collection for the year number 730 
trays. 
In the care and arrangement of the various study collections 
important work has been accomplished, the details ot which will be 
found in the reports of the several sections- -that on the Conchologi- 
cal collections by Dr. Pilsbry ; the Ornithological by Mr. Stone ; 
the Botanical by Mr. Stewardson Brown, and the Entomological 
by Dr. Skinner. 
In the rearrangement of the Museum the most notable work has 
been the installation of nearly oue-half of the mounted birds in the 
cases provided for them in the new building. The specimens have 
been carefully examined by the taxidermist and labeled and 
arranged by Mr. Stone. Almost all the water-birds and the 
greater part of the G allin acem have been transferred, and the floor 
will be ready for opening in the spring. 
Reari'angement of the mounted mammals has been made neces- 
sary by the addition of new cases, and the moose and other exposed 
specimens have been placed under glass. Several attractive 
mounts have been prepared during the year, notably the groups of 
Siamangs collected and presented by Mr. Alfred C. Harrison, Jr., 
and Dr. II. M. Hiller.
