5A4 ENTOMOLOGICAL INSTRUMENTS, &c. 
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 cf a proper 
width to closely receive the rabbet, and likewise to con- 
tain the camphor for preserving your insects from the 
attack of Acari, &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 toolong. 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? and neatly 
papered, first divide each transversely by a fil 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
