mens and books, and a large table for the various operations of 

 experimental work, with numerous drawers and compartments for 

 working material, have been constructed. 



One of the possibly unavoidable limitations, — among those affect- 

 ing both the quality and quantity of the work in this laboratory, — 

 is that of proper working space. There are needed a small room 

 for instruments and apparatus, one for the operations of sterilizing, 

 etc., and another for artificial cultures, wherein the conditions 

 necessary to such experiments, especially those of temperature, 

 could be controlled. Provision for these would greatly improve 

 the means for successful work.
