21. Setting Needle (PI. 3, figs. 13, 14, 15) 
is simply a needle fastened into a thin piece of 
wood about three inches long ; on the other 
end of which a camel’s hair pencil may be 
secured. A pin curved towards the point, 
and fastened into a piece of wood, will also be 
found useful. These instruments are necessary 
for extending the wings and legs of insects; 
and the pencil for brushing off dirt, or extend- 
ing the antennae and legs of those which are 
minute. 
22. Braces, are merely triangular slips of 
card used for confining the wings, &c. of the 
larger species. They should be made of stout 
hotpressed writing paper for delicate insects. 
23. Setting Boards are pieces of board 
covered with cork and papered. The cork 
should be close grained, a quarter of an inch 
thick, and perfectly smooth. To dry insects, 
and at the same time to secure them from ac- 
cidents, a box about a foot high, and nine 
inches square, having grooves in the sides t’lree ' 
inches apart for the setting boards to slide in, 
is necessary (PI. 3, fig. 16). The door mcy be 
merely a frame covered with muslin or wire 
gauze to admit air. At the bottom a drawer 
may be constructed, with divisions, for holding 
pins of different sizes, braces, setting needles, &c.
