omplete, but if required for an incomplete collection, the risk and annoyance of unscrewing and screwing up, to constantly remove or insert a specimen, are great. In view of the almost impossibility of keeping dust out of even the best-made cabinet drawers, if made on the top-lifting system, and also to do away with the screws, I have devised what I call the "dust-proof cabinet drawer." The glass is "beaded" and puttied in as a fixture on the top of the drawer, either from the inside or out. At the usual distance from the glass, to clear the pins, a strip is fixed all around the frame of the drawer. Below this, at a depth settled by the thickness of the bottom, a groove runs all around, except at the back, which is cut out up to the bottom edge of the groove. The bottom, when corked and papered, fits inside the frame, "butting" up to the strip which clips it all around to about the width of 0.25 in. A false bottom now slides in the groove below, and fastens with a catch, making all perfectly secure and altogether dust proof. If well made, this drawer is easy to open, as, directly the false bottom is removed the inner one slips down and is found on the table when the upper part is lifted off. The only thing to be said against this drawer is that the fronts show a little deeper than usual to allow for the extra bottom. A modification of this is a closely glazed cabinet drawer, with a false corked bottom, loosely held down by a slip affixed to each side of the drawer, and sliding out from the back; managed by hinging the back piece or fixing it by brass eyes and hooks. Note, that all loose flaps to drawers or door-frames, in best cabinet-work, should be worked and fitted by "Dust-joint" planes. This reduces risk and dust to a minimum. PINS.--The pins used are those called entomological, and are made in various sizes to suit various insects. An insect should be pinned with one of these exactly in the centre of the back, running through truly to the underneath, slanting, however, a little downward toward the body, thus throwing the pin's head a little forward, but exactly in a line with the longest axis of the body. These are specially made by one or two firms only. Messrs. D. F. Tayler and Co, of Birmingham, issue a sample card, the most useful sizes of which are No. 11 (at 6d. per oz.) for the hawk moths, No. 13 (at 6d. per oz.) for smaller moths and butterflies, and No. 7 (at 2s. 6d. per oz.) for small moths, and
