solidly together, but independent of the wall, so that they can be moved bodily 

 without great inconvenience when it is necessary. They could, if the space 

 were needed, be placed out in the hallway. Each locker is 12 x 14 inches, and 

 is 15 inches in depth, and each has a combination lock, the combination being 

 known only by the student who uses it and by the director of the laboratory. 

 The combinations can be changed from time to time as circumstances may 

 demand. This plan avoids all confusion over lost keys and allows the labora- 

 tories to be kept open all day so that students who wish to make up back work,

etc., at irregular hours, can do so even though the one having the laboratory in 

 charge is not present. 



Your readers will recognize the microscope cabinet (Fig. 5) as a modification 

 of one previously described in the pages of this journal (Vol. I, p 29), Each 

 receptacle in this cabinet is 10 inches wide and 12 inches high, and is deep 

 enough to hold two microscopes. One row of lockers across the cabinet is dis- 

 placed by drawers, each having lock, for the storage of cover glasses, extra 

 oculars, micrometers, etc. Two or three of the receptacles have special doors 

 and keyless locks and are thus protected while the outer doors are open. When 

 needed regularly the microscopes are left out on the tables and are covered, when 

 not in use, by cardboard cones. The cabinet affords a safer place for keeping 

 them during vacation, or when not needed daily.
