218 THE CANADIAN ENTOMOLOGIST. 



and fitted into the bottom of drawers in a cabinet. Now I have gone a 

 step farther, and discarding the drawers entirely, have adopted the frames 

 and adapted them to a cabinet without drawers. This cabinet can be 

 made of any size and be divided by upright partitions to suit the taste of 

 the owner, and the frames can run in grooves made in the sides and par- 

 titions before it is put together, or between movable strips tacked or 

 screwed in afterward at suitable distances, say two inches. The one I now 

 use (a small one made as an experiment) is three feet two inches wide 

 inside, with two partitions, so that there are three spaces each one foot in 

 width. It is fifteen inches deep and two feet high. Placing the frames 

 two inches apart gives me twelve in each section, or thirty-six in all, and 

 as each has a surface of twelve by fifteen inches, I have an aggregate 

 expanse of thirty-six square feet. The advantages claimed for this cabinet 

 are its lesser weight and expense. It is easily handled and can stand 

 pretty rough usage without fear of damaging specimens, as the pins are 

 firmly held, and the frames, running in grooves or between strips, cannot 

 stir when the door shuts close against them. It does away with the 

 expense of drawers, the cork alone for which (thirty-six feet at 18 cents 

 per foot) would be $6.48. The frames constructed of thin stuff (say 

 quarter-inch) cost at the most five cents each, and suitable stiff cartridge 

 paper is very cheap. If the frames are made slightly smaller than those 

 mentioned, one sheet will cover both sides of two frames. The paper is 

 put on when damp, but should not be too wet. The frames can be easily 

 re-papered if needful, and if the sections are made of equal width, they 

 will all be interchangeable, which will be found a great convenience. 



This manner of keeping specimens will, I think, be particularly useful 

 to collectors of Coleoptera. I send this, feeling .that each member of the 

 Society should contribute his mite of experience and knowledge for the 

 benefit of his fellow-workers.
