npHIS brief history of the Academy of Natural Sciences 



of Philadelphia was prepared as a contribution to 



the volume issued in commemoration of Founders' Week, 



so successfully celebrated from the fourth to the tenth of 



^ October, 1908. 



fO The length of the article was determined by the 



number of pages available in the distribution of the matter 



composing the book and the story is, therefore, necessarily 



I "short." The Notices of Morton and Euschenberger have 



been of assistance in preparing the earlier portion. 



The sketch may be regarded as merely preliminary 



^ to a detailed history of the Academy to be issued in 



- ^ connection with the proposed celebration of the Cente- 



g nary of the society in 1912. It is sent out in this form 



^ with the hope that it will, by eliciting comment, criti- 



- cism, and perhaps correction, help to make the larger 



*l work of more permanent value. Any assistance to this 



end will be gratefully accepted by the author.
