some bits of blotting paper and camphor 
therein : they must be killed with scalding 
water, then thoroughly dried and packed away 
in tin boxes, placing layers of cotton between 
them, sprinkled with turpentine and camphor. 
A large sugar or tea canister would be an 
excellent depot. It must be made to close 
very tightly. 
Butterflies, moths, and flying insects of all 
kinds, must be carefully caught and pinched 
on the breast sufficiently hard to kill or at 
least to paralyse them; they should then be 
pierced with a pin adapted to their size (but 
never with needles). Butterflies only should 
be pierced laterally through the thorax, and 
the horns placed between the wings. As 
soon as convenient the insects, if not dead, 
should be pierced in the breast with a pin 
dipped in aquafortis or oxalic acid. To save 
room and pins, two or more butterflies may 
be transfixed on one pin. Never attempt 
to set their wings out unless under very fa- 
vourable circumstances, for this can be done at 
home, which will be a saving both of time
