The author manufactured a homogenizes which can very easily have a uniform distribution of the diseased moth of silkworm, infected with pébrine. This machine is composed of a receptacle, so-called drum, which receives moths and of a water-tank which absorbs the scale of moths.<br>The former is the drum, which mixes moths. It is rotated by a stepped pulley, the velocity of which can be changed in three steps. In the drum, a agitation vane is inserted at 45 angle to the base. It serves to mix moths twice per rotation of the drum. Because, the vane brings the falling position of moths in the former half of one rotation to the fore part of the bottom of the drum and the latter half to its rear part or viceversa. Just behind the drum, this apparatus is provided with an electric fan, the rotation of which is about 4, 000r.p.m., in the metallic cover. The scale of moths is sucked by the suction power of the fan through the wire-netting, fixed to the hind cover of the drum, thus not only facilitating the microscopical inspection of ground moths by clearing the field but also by protecting healthy moths from contamination by the scale, heavily infected with pébrine. Moreover, absorption of the scale serves to keep the worker's sanitation, as the air of the room may not become dirty. The drum is made of acrylite (a name of stolen goods, made chemically of acrylic resin), so that the state of mixing manner of moths can easily be observed during rotation. Besides, in the case of the fore cover, as it is especially easy to fit it into the position or to remove it, so the manipulation of putting moths into the drum or taking them out from it is also done with no difficulty.<br>The latter is the water-tank, which receives the scale, blowed out through the wide suction pipe made of gum, which connects the former and the latter. It contains water and the large scale is absorbed in it. The upper part of the tank consists of the large tubular cover, whose side is covered by the bleached cotton-cloth and whose top is covered by the metallic plate. This cloth serves to catch fine scales and to pass out the air blowed in the tank. The surface of water is indicated by the level gauge.
