1880 ] NATURAL SCIENCES OF PHILADELPHIA. 401 



Academy's propert^^ This time is employed in work incident to 

 taking care of, mounting, and arranging specimens in the museum, 

 such as cleaning them when necessary, labeling, etc., a kind of 

 work which is pertinent to the vocation of a naturalist, and 

 throuffh which the beneficiaries become familiarized with natural 

 objects, more perfectl}^ than thej^ can be in any other way. It 

 should not be forgotten that the Academy has alwaj-s been de- 

 pendent, almost exclusivel}', upon the unpaid labor of its members 

 for the care of its museum, and this circumstance, perhaps, ex- 

 plains why beneficiaries of the Jessup Fund are expected to do 

 an}' kind of work in the Academ}- that the curators and other 

 members are in the habit of doing. They are, in fact, regarded 

 as almost apprentices, who should be ever ready to avail them- 

 selves of the opportunities afforded to learn everj'thing pertinent 

 to the career of a naturalist. 



Applications for the benefits of the Jessup Fund, are considered 

 and decided by the Council of the Academy. 



Between March, 18G0, and November, 1880, thirty-four persons 

 have received aid from the fund, for a longer or shorter period 

 than two years. Of these, five have died, well known and much 

 respected naturalists. Five of those, now living, are professors 

 and eminent men. It is believed that all of this class of gentle- 

 men have acquitted themselves satisfactorily, and that all grate- 

 full}^ appreciate the benificence of the Jessup Fund, as well as 

 the advantages derivable from it ; and it is hoped that none will 

 ever regret an}- of the work he has done, or the time he has spent 

 in the Academy. 



The annual reports of the curators and librarian show the ex- 

 tent of increase of the museum and- library ; and those from the 

 several sections of the Academy indicate that they are active and 

 prosperous. 



During the year, more than 600 pages of the Proceedings have 

 been published, and the fourth part of the eighth quarto volume 

 of the Journal of the Academy is passing through the press. 



The proceedings of the Entomological Section are printed on 

 the premises by some of its members, and issued separately. 

 This section has published more than 370 pages and 7 plates 

 during the year.
