Notice of Scientific Socteties. 375 
28. Linnman Society. Philadelphia. Instituted 1807. 
We believe that the members of this society have ceased to 
assemble for sometime past. It was founded by the late 
Professor Barton, whose discourse On some of the principal 
desiderata of American Natural History, was pronounced at 
the opening of this institution. 
24. Acapemy or Narurat Sciences. Philadelphia. Ine 
corporated in 1818. Meet weekly. This active society has 
already published four volumes octavo, under the title of 
Journal of the Academy of Natural Sciences, and have nearly 
completed a fifth volume. It has the most complete and ex- 
tensive library of works upon Natural History, in the United 
States, for which they are chiefly indebted to the liberality of 
Mr. Maclure, a gentleman equally celebrated for his zeal in 
prosecuting scientific inquiry, and his generosity towards 
those engaged in similar pursuits. The Journal of the 
academy, is absolutely indispensable to every American Na- 
turalist. | 
In addition to the means of acquiring scientific information, 
afforded by these Societies in Philadelphia, the University of 
Pennsylvania, has a professorship of Natural History, at 
resent filled by Mr. Thomas Say. Dr. Hare is professor of 
Shemistry ; Mr. W. H. Keating of Mineraloy, applied to the 
arts; Dr. Barton of botany, and Dr. Hewson of comparative 
Anatomy. No salaries are attached to these professorships, 
and they are compelled to give at least ten lectures annually, 
The Philadelphia museum was incorporated a few years 
since, and as a corporate body, were privileged to appoint 
Protessors. Accordingly the following gentlemen have been 
elected, and have already given several courses of lectures. 
Dr. Troost, on Mineralogy and Geology, Mr. Say, Zoology, 
Dr. Godman, Physiology, and Dr. Harlan, comparative 
Anatomy. It is gratifying to see in one city, these various 
efforts to promote and extend the study of the natural scien- 
ces: may others follow this good example. 
25. Acapemy or Science ann Literature. Baltimore, 
Maryland. Instituted 1821. Arrangements are making to 
commence a volume of their transactions. 
26. ContumsBian Institute. Washington City. Yncorpo- 
vated . The President of the U. States is, ex officio, the 
President of this society. Under its auspices a Florula Co- 
fumbiensis has been published, and spirited efforts are now 
making to establish a botanic garden.
