. Butterflies and moths (British). Butterflies; Insects -- Great Britain. SETTING AND PEESERVIXG 125 needle, fix each one by a pinned strip. In spreadin;:^ out the win^^s, care must he taken not to pierce them at all, but simply to push them into their place by pressinor the needle at their bases, or by putting the needle beneath and lifting them out. Instead of pointed pieces of card, uniform strips of paper may be used, as shown in fig. 63, each strip passing over both wings. After the four wings have been proi^erly arranged, a few extra pins may be used to keep other pai*ts in position. Thus, the antennae may be placed at equal angles, the proboscis may be ex- tended, and a couple of pins may be used to support the abdomen if it is inclined to bend downward. As before men- tioned, insects should be set soon after they are dead, while the parts are still soft and supple. But where this cannot be done, and the specimens have become stiff, brittle, and rigid, thej' must be ' relaxed' before any attempt is made at setting them out. This process of re- laxing consists in plac- ing the specimens in a very moist atmosphere for a few days. There are several simple ways of doing this, many of which will I'eadily suggest themselves to the reader. Your collecting box, if a zinc one, may also be used as a relaxer. Pin j^our stiff insects in it, after well moistening the cork, and simply shut them up for a day or two. Any metal box will serve the same purpose providing you put into it a piece of sheet cork on which to fix the insects, and this cork may rest on a bed of moist sand. Another plan is to float the pinned specimens on corks in a shallow vessel of water, and cover them over with a bell glass. Insects that are being relaxed should be examined from time to time, and the degree of flexibility acquired tested jy a gentle. Fig. 63.~-ANOTnF.R Mkthod of Setting Butterflies anp Moths..
