the same period, was made, the results being published in 

 Volume I, Number i of the Proceedings. 



The activity of the biological students of the Institute has 

 led to the purchase recently of a number of standard works 

 on biology and biological chemistry. Among these are : 

 "Text Book of Zoology," Weysse ; "Protozoology," Cal- 

 kins, and " The Microscope," Carpenter. 



C. Edgar Ogden has recently presented to the museum of 

 the Institute a number of fine specimens of minerals collected 

 during a recent visit to Florida and the South. The mineral 

 collection of the Institute is quite large, and donations of 

 this class are very welcome. 



Dr. B. M. Underbill has presented to the museum of the 

 Institute a dissected crayfish, nicely mounted on cardboard, 

 with the various parts numbered and named. The crayfish is 

 a type form for biological study, and the donation is much 

 appreciated. 



The present number of the Proceedings completes Vol- 

 ume V. The cordial welcome which our publication has 

 received from other societies and journals is a source of grati- 

 fication to the Publication Committee. 



The naturalists of the Institute are contemplating several 

 biological and mineralogical excursions to points of interest 

 in this section during the summer.
