The drawers (Fig. 118, A, B, C) are square, with an outside measurement of 18 inches and an outside depth of 3 inches. The sides and back have a thickness of three-eighths of an inch, while the front is five-eighths of an inch thick. The pieces are firmly dovetailed together, the front being clean and the dovetailing blind. The bottom, _a_, is of three-ply crossgrained veneer, run into a groove at the sides, leaving a clear inside depth of 2 1/16 inches to the frame of the cover. The bottoms are lined in all but forty of the drawers with first quality cork, _b_, one-fourth of an inch thick. At a distance of one-fourth of an inch from the sides and back and three-eighths of an inch from the front there is an inside box of one-eighth inch whitewood, _c_, closely fitted, and held in place by blocks between it and the outer box. There is thus between the inner and outer box a clear space, _d_, all round, in which insecticides or disinfectants can be placed to keep out Museum pests, making it impossible for such to get into the inner box containing the specimens without first passing through this poison chamber. The entire inside is lined with white paper, or, in the case of the uncorked boxes, painted with zinc white. The front is furnished with a plain knob. The cover is of glass, set into a frame, _f_, three-fourths of an inch wide, three-eighths of an inch thick, with a one-fourth inch tongue fitting closely into the space between the inner lining and outer box, which here serves as a groove. This arrangement furnishes a perfectly tight drawer of convenient size and not unwieldy for handling when studying the collection. The material of which these drawers are made is California red wood, except the cover frame, which is mahogany. The cabinets containing these drawers are 36 inches high, 40 inches wide, 21 inches deep (all outside measurements), and are closed by two paneled doors. Each cabinet contains twenty drawers in two rows of ten each, and the drawers slide by means of a groove, _g_, on either side, on hard-wood tongues, and are designed to be interchangeable. _The Lintner display Box._--For beauty and security and the perfect display of the larger _Lepidoptera_, I have seen nothing superior to a box used by Mr. J. A. Lintner, of Albany, N. Y. It is a frame made in the form of a folio volume, with glass set in for sides and bound in an ordinary book cover. The insects are pinned onto pieces of cork fastened to the inside of one of the glass plates and the boxes may be stood on ends, in library shape, like ordinary books. For the benefit of those who wish to make small collections of showy insects, I give Mr. Lintner's method, of which he has been kind enough to furnish me the following description:
