cement. The remaining wall space of the laboratory is occupied by shelving 

 and racks for apparatus, glassware, tools and the like. 



In the center of the room stands, upon the floor, a cement tank (Figs. 3 and 

 4), into which open several taps to which may be attached aspirators, or water 

 motors for keeping clinostats in motion. Behind the tank is a potting table sup- 

 plied with convenient bins for holding clean sand and soil, and a fine spray rose 

 for moistening the soil as needed. 



The lighting of the room, an important desideratum, is modified at pleasure 

 by means of shades of jute bunting, which allows the direct sunlight to pass 

 through, but at the same time considerably lowers the amount.
