PROCEEDINGS OF THE ACADEMY OF 
[Dec., 
tions before the society. The specialists have continued to hold 
their independent meetings with most satisfactory results. Of 
late years, by a mutual arrangement, the several Sections have been 
given precedence at certain specified meetings of the Academy, 
with the object of bringing before the general meetings the more 
important communications presented at the less formal Section 
meetings. 
With the object of fostering and encouraging small scientific 
organizations, especially those composed of younger students, the 
Academy has freely granted the use of its halls for meetings, and 
during the past decade the Geographical Society, Delaware Valley 
Ornithological Club, Philadelphia Botanical Club, Students’ Min- 
eralogical Club, Students’ Entomological Society, Mycological 
Club, Leidy Association, Philadelphia Moss Chapter, Wood’s Hole 
Biological Association, Odontographical and Anti-Tuberculosis 
Societies and Pennsylvania Audubon Society have availed themselves 
of this privilege, thus bringing many people in touch with the 
Academy and eventually adding to its membership. 
Besides these organizations, a number of State and National 
societies have, during this period, been invited to hold their con¬ 
ventions in the building, notably the American Society of Natural¬ 
ists, in 1891; the Pennsylvania Veterinarian Society, in 1894; 
and the American Ornithologists’ Union, in 1899. 
The Proceedings and Journal of the Academy have been issued 
continuously since 1881, as previously. Twenty-one volumes of the 
former and four of the latter have appeared, comprising in all 
12,100 pages. These contain contributions not only from the 
members of the Academy, but from eminent scientists from various 
parts of America and Europe. 
During the past twenty years the Proceedings have been sent in 
exchange to a constantly increasing list of scientific societies 
throughout the world. Beginning with the year 1900 the Acad¬ 
emy, through its increased endowment, has been enabled to distrib¬ 
ute the volumes to its members, a course that had long been 
desired. There have also been issued from the Academy and 
allied societies the Transactions of the American Entomological 
Society, the Entomological News, and the Manual of Conchology, 
while the Nautilus has been edited by the Conservator of the Con- 
chological Section.
