436 PROCEEDINGS OF THE ACADEMY OF 



About 863 species have been sent to Chicago to assist in replac- 

 ing the collection of the Chicago Academy of Sciences, lately de- 

 stroyed by fire, and upwards of 100 additional species are now 

 ready for transmission. These have all been correctly determined 

 and named. 



In thus announcing the completion of the labor of seven 3'ears, 

 this rei)ort would not be complete if special mention were not 

 made of the gentlemen who have devoted so much of their time 

 and skill to the work. A bare statement of the fact that every 

 one of tl)e 14,161 species contained in the collection has been 

 separately and carefully examined by Mr. Trj'^on, that he has de- 

 termined nearly' all the species not hitherto named, and verified 

 the names already given, will be sufficient to show how much the 

 Academy is indebted to him for his unflagging industry. To tlie 

 taste and skill of Mr. Parker, who has thus employed most of the 

 time not occupied by other duties, is mainly due the admirable 

 manner in which the specimens are so arranged as to exhibit the 

 specific characters without the necessity of handling. Mr. Roberts 

 has also devoted mucli of his leisure time to the same work, while 

 the report of what has been done by Dr. Hassler in the disposition 

 of the duplicates, bears ample testimony to his industry. 



It is already well known to the members of the Society that this 

 labor has been entirely voluntarv. It has been, in truth, a labor 

 of love, and the elegance of the arrangement, no less tlian the 

 comparative completeness of the collection, is sufficient evidence 

 of the earnestness with which all concerned have fulfilled their 

 self-imposed task. 



All of which is respectfull}' submitted, 



Edw. J. Nolan, Conservator.
