net bottom, a wardrobe case (used in our laboratories mostly for apparatus and 

 reagents), teacher's desk and chair, complete the furniture for the three rooms. 

 Besides these there is in the zoology room a slated (chemical proof) four-com- 

 partment sink, with hot and cold water faucets, five basins also with hot and cold 

 water, a double-deck aquarium table with four large plate-glass aquaria below and 

 three smaller ones above, all supplied with running water for breeding and keep-

 was placed on the side most strongly illuminated, and in three weeks the algae 

 accumulated in this pattern, forming the letters in deep green. It has lasted over 

 six months. 



We have a typewriter for manifolding our laboratory directions, reviews, and 

 examination questions. The new terminology is usually quite enough for the 

 student beginning any study not to vex him with reading it in an unfamiliar hand.
