Some of the Work of the Wagner Free Institute of Science of 
Philadelphia. By Joseph Willcox. 
As the representative of the Wagner Free Institute of Science 
invited to participate in the celebration of the 150th anniversary 
of the American Philosophical Society, I have thought it proper to 
make a few statements concerning some of the work of the Wagner 
Institute, a colaborer with this’ Society in the same field of useful- 
ness. 
Though young in age, the Wagner Institute has endeavored to 
profit by the experience of older institutions. It was established by 
the late Prof. William Wagner who, in the year 1847, gave a 
course of free lectures on scientific subjects at his house. The suc- 
cess of this experiment encouraged him to found an institution for 
‘instruction in science, to include a museum of natural history 
specimens, a laboratory for physical and chemical students, a 
library and a lecture department. 
The building of the Wagner Free Institute of Science was com- 
pleted in 1864, and from that time until Prof. Wagner’s death in 
1885 courses of free lectures were maintained on scientific subjects 
during each succeeding winter. 
Prof. Wagner spent a large portion of his life in accumulating 
and husbanding resources for the future use of the Institute.
