ENTOMOLOGICAL INSTRUMENTS, &C. 557 



beted underneath ; and parallel with the sides of the 

 drawer, but a little lower, there should be inner side- 

 pieces fixed, so as to form a cavity all round of a proper 

 width to closely receive the rabbet, and likewise to con- 

 tain the camphor for preserving your insects from the 

 attack of mites, &c. ; to emit the scent of which, many 

 holes should be bored in the side-pieces. Each cabinet 

 may contain forty of these drawers in a double series, 

 protected by folding doors ; and you may place one ca- 

 binet upon another, if your space admits it. You will 

 find a tool used by bell-hangers for cutting their wire 

 very convenient to behead or otherwise curtail the pins, 

 as those with which foreign insects are transfixed are 

 often too long. If you cut them off below the insect, cut 

 them obliquely, which will leave a point that will enter 

 the cork. 



When your drawers are smoothly corked a and neatly 

 papered, first divide each transversely by a full black 

 line ; parallel with this, on each side, draw a line with 

 red ink : then, for arranging your insects, draw pencil 

 lines, which are easily obliterated, at right angles with 

 the others, according to the general size of the insects 

 that are to occupy them. Insects look better thus ar- 

 ranged in double columns, than if the pencil lines tra- 

 versed the whole width of the drawers. In arranging 

 them, you may either place them in a straight line be- 

 tween the pencil lines, which I think is best, or upon 

 them. You will begin your columns from the red lines 

 in the middle, and not from the sides of the drawer; thus 

 the heads of those on one side of it will be in an opposite
