These are easily attached, and are the most satisfactory arrangement for this 

 purpose that I have seen. 



Lecture tables are 10' long, with a closet and drawer at either end, and 

 a solid back. The tops are blackened like those of the other furniture. 



All sinks are of soapstone. Water is supplied to the aquarium sinks in the 

 usual way— that of a pipe running longitudinally, 3' above the sink, with a series 

 of small "pet-cocks" on the under side. A number of these small cocks 

 arranged over the sink in the preparation room, provide small streams of water 

 for washing out purposes. On each floor a small water heater fastened over the 

 sink furnishes hot water. 



The general arrangement of the rooms is given in the accompanying dia- 

 grams of the ground plan of each floor. At the right of the main entrance on

the first floor is the laboratory for advanced Zoology and Embryology. This has 

 ten students' desks facing the windows, with arrangements for a second row 

 behind the first. The arrangement of the other furniture is shown in the dia- 

 gram. Not shown there, is a small corner set of shelves, used for holding 

 reagent bottles. 



Behind this is the Botany supply room, containing the herbarium, a case for 

 supplies, and a desk for microscopical work. This latter is of the same height 

 and width as the students' desks, but extends in front of the window for the 

 whole width of the room, being thus 10' long. A row of drawers runs down the 

 middle, leaving working space on either side. A similar table is in the private 

 office and in the preparation room on the second floor. (See photograph, 

 Fig. 6.)
