Insects (To Prepare For Cabinets). The mode adopted for killing insects for preservation in cabinets varies with the different tribes. Dark coloured beetles may be plunged as captured into a bottle containing spirits of wine, and, on reaching home, they may be dipped for an instant into scalding water, dried on blotting-paper, and are ready for the cabinet. Those of delicate colours may be fixed in a tight tin box, which may be plunged for a few moments in boiling water. Butterflies, moths, and dragon-flies, may be killed by sharply pressing the thorax without injuring the wings, and then pinned ; or the pin may be dipped in a strong solution of oxalic acid before being used. Large moths and dragon-flies, which are exceedingly tenacious of life, may be instantly killed by holding the wings above the back, and dipping merely the under surface of the body for an instant into scalding water; or they may be fixed to a cork, tightly wedged into the bottom of a gallipot, which is to be then inverted, and plunged mouth downwards into boiling water. By far the greater number of insects are killed immediately, if a few bruised laurel leaves, which exhale prussic acid, are kept in the collecting box. The fumes of burning sulphur should not be employed, as they injure the colours of insects considerably. Parasites, which infest birds, and others of small size, may be conveniently put into a quill, which, after corking, may be dipped into boiling water.
