laboratory course. Students often pass to and fro from table to locker, causing 

 more or less jar and vibration, especially annoying if microscopical work is going 

 on. Such an arrangement is doubly inconvenient. It is annoying to the student 

 to be obliged to go from table to locker. It is also annoying to his fellow 

 workers to have him do so. 



The combined lockers and table obviates these disadvantages. Each table 

 contains four lockers and two students can work at one table and have their 

 apparatus right at hand. Twelve tables will provide lockers for forty-eight 

 students and twenty-four students can work at the tables at one time.

The table would appear to be useful for biological work in general, although 

 in certain cases a proportionate change in dimensions may be desirable. 



The cost of the combined locker-table is less than the total cost of a table and 

 four lockers built separately. In lots of one dozen, the combined locker-table 

 including a combination lock for each locker can be built in red oak for four- 

 teen dollars each, or in chestnut for twelve dollars each. The writer has used 

 these tables for nearly two years and has found them satisfactory in every way.
