Journal of Applied Microscopy 



Each desk is provided with an adjustable stool. In my experience no other 

 laboratory seat is satisfactory. 



Desks for holding paraffin baths, sterilizers, etc., are 3' 4" high and 2' 6" 

 wide. They have closets at either end with three rows of drawers down the mid- 

 dle, and are arranged to stand against the wall. For desks of this sort fire-proof 

 tops are essential, and we have adopted soapstone in preference to slate, on 

 account of the tendency of the latter material to crack under the heat of a steril- 

 izer. In the laboratories, these desks are 10' 6" long. A smaller one in the 

 preparation room is 5' long, but with the other dimensions the same as 

 these. 



The soapstone tops of these desks, as well as those of the sinks, are filled 

 with oil which turns them black, thus matching well the tops of the tables, and 

 shows stains much less than would the natural color of the stone.

Demonstration tables standing in the laboratories, behind the students' 

 desks, are 31" high, 34" wide, and 8' long. Each has a closet at either end with 

 two rows of drawers in the middle. The tops are blackened like those of the 

 students' desks. 



Wall cases are 8' 6" long, and 8' high. Below are closets, 3' high and 2' 

 deep. Above are cases with glass sliding doors 5' high and 18" deep. The 

 latter have adjustable shelves. 



For convenience in keeping a card catalogue of apparatus and other equip- 

 ment, each piece of furniture is lettered, and each shelf and drawer in it is 

 numbered. For this numbering we have adopted a small brass thumb tack, with 

 black enameled number, such as is used by manufacturers of window screens.
