SETTING NEEDLE. 
This instrument is fixed to the stalk of a common 
hair pencil, and is used for extending the parts of 
insects, such as their limbs, antenne, win gs, Xe. 
On the opposite end of the stick there ought to be a 
hair pencil, for the purpose of removing any dust 
which may fall upon them. 
—) 
This is another kind of Setting Needle, the use 
of which will be obvious. 
PINS. 
The pins used for insects are the small lace kind, 
and made very fine for the express purpose ; they 
ought to be well tinned, to prevent the juices of 
the insect from acting on them, and thus producing 
* verdigris, which destroys the insects. 
SETTING BOARDS. 
These consist simply of convenient sized thin 
deal boards, and covered with a thin layer of cork ; 
which ought to be perfectly level on the surface, and 
covered with white paper.
