Several boards will be required, by persons who are making | 
collections, as some of the insects take a considerable time to 
_ dry, so that they may be fit for introducing into a cabinet. | 
_ The boards should be kept in a frame made for the purpose. | 
It should consist of a top, bottom, and two sides; the back and 
_ and their centres covered with fine gauze, for the free passage 
_ of air; the sides should have small pieces of wood projecting 
from them, for the boards to rest on; which should be at such 
al 
a distance from each other, that the pins may not be displaced, | 
in pushing the boards in, or drawing them out. The frame 
should be placed in a dry airy situation. 
Braces.—These are merely small pieces of card, cut in the 
form exhibited on plate IV., attached to the Butterfly, and 
| other insects; and also at No. 17. They are pinned down on 
the insects, to keep their wings, &c., in a proper state, till they 
acquire a set. 
SETTING AND PRESERVING iNSECTS.

These are very easily preserved. 
They are killed by immersing in scalding water, and then

_ laid upon blossom or blotting paper, for the purpose of absorb- 
ing as much of the moisture as possible; or they may be placed 
in a tin box, with a little camphor in it, near the fire, which 
soon kills them. This is besides of considerable effect in their 
preservation. 
Insects of the genera Gryllus (Cricket), Locusta (Locusts), 
_ &c., have tender bodies, and are sure to shrivel in drying. 
The intestines should therefore be extracted, while they are 
yet moist, and the skin filled with cotton, as directed with some 
of the spiders, at page 72. 
When Coleopterous insects are set with the wings displayed, 
the elytra should be separated, and the pin passed through 
their body, near the middle of the thorax, as in plate IV., fig. 
3,a. The wings are exhibited as in the act of flying, and 
are retained in this situation until they are quite dry, by the 
cord-braces, band c. The insects of this order should always
