Collier's New Encyclopedia (1921)/Philadelphia Academy of Natural Sciences

PHILADELPHIA ACADEMY OF NATURAL SCIENCES, an association formed to promote the study of natural sciences, discuss subjects of scientific interest and encourage research in the physical sciences. For the latter purpose the Jessup Foundation has sufficient funds to provide free tuition for younger investigators interested in the sciences. The museum maintained by the society is reputed to possess the finest collection of shells in the world, and has many numerous and valuable collections of birds and fossils. The library of 80,000 volumes contains the records and proceedings of all the learned societies in Europe and America which have been published since the foundation of the society in 1812. Since 1817 the Philadelphia society has published a “Journal” and since 1841 its “Proceedings.”
