Record. lix 



To the teacher and student of science, the laboratory is not 

 everjrthing. While he may gain new knowledge in the labora- 

 tory, he must refer to the records of the workers who have gone 

 before for the successful prosecution of his own study and in-

 may waste much time in doing over again what has already been 

 well done, or in following paths that have already been well 

 trodden. In accumulating the treasure of human thought in 

 the past, we prepare the way for the development of additional 

 and greater treasures of human thought in the future. 



Respectfully submitted, 



Mary J. Klem, 

 Librarian. 



Curators' Report.

 from Veedersburg, Ind. ; and a specimen of Melonites multiporus 

 from Tennessee. 



The most pressing need of the museum is cases for the exhibi- 

 tion of the collection. The question of furnishing our museum 

 and installing our exhibits properly is a matter of great impor- 

 tance. Cabinets suitable for displaying specimens should be 

 provided. We desire to again urge upon the members of the 

 Academy the necessity of securing these pressing needs. Cases 

 are as necessary in a museum as shelves in a library. 



Our special aim should be to make complete collections of all
