122 THE AMERICAN NATURALIST [Vol. XL VII 



Below the case proper is a shelf to hold laboratory books. An 

 improvement over the ease here shown would be to have two 

 shallow shelves, in place of one, divided into sections for the 



further alphabetical distribution of the books. The case here de- 

 scribed is 84 inches high, 51 inches wide, and 13 inches deep, 

 outside measurements. 



There is wasted, of course, a vertical strip about four inches 

 wide in the center of the case where the doors overlap, but it is 

 always hidden, whether the doors be open or shut. 



Such a case, if well made, is practically dust-proof, and is eco- 

 nomical not only of space but of money as well, since the cost of 

 the individual microscope boxes may be saved in buying new in- 

 struments. A case similar to this has been used by the writer for 

 several years and has proved entirely satisfactory.
