on the Jessup Fund, for the care of this department. Mr. Gordon 
has labelled and catalogued a number of accessions to the Wm. 
S. Yaux and the general collections and prepared a check list of the 
entire series. The William S. Vaux collection now numbers about 
9,000 specimens, nearly half of which are on exhibition; the Academy 
general series, 10,500 specimens, of which about 1,000 are exhibited, 
and the Adam Seybert collection, which is kept separate, 1,825 
specimens, while there are 80 falls of meteorites represented. 
The duplicate specimens not on exhibition are arranged sys¬ 
tematically in storage cases immediately below the exhibition series 
so that they may be consulted with the greatest ease. 
Air. Gordon has overhauled a large number of mineral and rock 
specimens received at various times and cleaned and labelled such 
as are of value. The rock series now in the Academy’s possession, 
including the first and second Pennsylvania Geological Survey col¬ 
lections, amounts to about 19,000 specimens. 
The most important accession during the year was the Mrs. W. 
A. Drown collection, presented by Miss Emily Drown, comprising 
some 6,000 specimens. It was especially notable for the large num¬ 
ber of species represented, a number of which were new to our 
collection. 
Archeology. 
Miss H. N. Wardle has overhauled several thousand specimens 
mostly belonging to the Haldemann collection, which were stored in 
the basement, and has cleansed and identified them, entering some 
2,000 in the catalogue. Little new material was obtained during the 
year. 
Mr. Clarence B. Moore’s expedition during the spring of 1918 
explored territory along the Apalachacola River, the Flint River to 
Bainbridge, Ga., and the Florida coast from St. Andrew’s Bay to 
Crystal River. The result demonstrated how thorough had been 
his earlier exploration of the same region, as little new material was 
obtained. Pottery and artifacts regarded as duplicates were pre¬ 
sented by Air. Aloore to the Museum of the American Indian, 
Heye Foundation. Owing to necessary repairs to his boat Air. 
Aloore was compelled to abandon his usual autumn expedition. 
Throughout the year the undersigned Curators have been without 
the advice and counsel of their associate Maj. Henry Tucker, who 
since the entry of America into the war has been in the service of 
his country in the medical corps of the Army.
