    Specification. Mennons Improved Apparatus for the Capsulation of Fluid Medicines. A is a cast-iron frame, on which are mounted the different parts of the combination; B is a slide piece, provided at its fore extremity X with a mould plate C1, corresponding with a second mould plate C, fixed to the support A. Each of these plates is surrounded by a moveable frame, serving as gauge for the quantities of plastic matter admitted by the capacity of the moulds ; these 5 frames project beyond the level of the moulds, in which position they are maintained by two springs set behind each plate ; opposite the extremity of each spring a hole is pierced through the plate for the reception of small stud pins, which bear on the springs and frames, in such a manner that the projection of the latter always corresponds with the thickness of plastic matter required. 10 D, E, closer (“ soudeur ”), composed of two parts, one of whicli (D) is moveable, while the other (E) is fixed to the frame (A,) and serving to close at their edges the strips of plastic matter F, F, so as to form a species of tube. This closing apparatus is set above the mould plates at a distance equal to the height of the latter; G, G, are bobbins, on which are rolled the strips of 15 paste E, F ; II is a glass funnel fitted with the stop-cock L, and with a socket, which, passing from end to end descends almost to the plate C ; I is a lever, by means of which is brought down the precise quantity of plastic matter required to cover the moulds ; J, fly wheel mounted on the end of a screw set in the slide piece B, and serving to move forward the mould plate C1 towards 20 its stationary counterpart C; K, fly wheel by which the closing apparatus is opened and shut; M, opening pierced through the framework A and table N, to give passage to the capsules produced ; T, pipe communicating with a steam boiler of any convenient form, by means of which the apparatus may be heated to a temperature of about 20° to 25° centigrade (=68° to 77° Fabren- 25 lieit) ; U, steam chest; Y, purge pipe. Figure 2 represents the arrangement by means of which the strips or bands of plastic matter are prepared for use. 0, O, is a metallic tablet of any required length ; say, for instance, six feet, by four inches in width, provided with edges forming at each side a ridge of about one-fiftieth of an inch in 30 height, coiresponding with the thickness to he given to the strip of paste ; P is a charriot or sliding box, in which is placed the hot plastic matter. In the bottom, and below the front of this box, is cut a narrow oblong slit, correspond¬ ing in length with the width comprised between the ridges of the tablet 0, 0; Q, key fixed to the stopper of the slit; R, slide piece worked by a screw S, 85 and serving to gauge the thickness of the paste. The charriot P being charged with the hot plastic matter, the slit is opened by a forward motion of the key Q, allowing the paste to flow along the tablet 0, 0. It is then moved forward to the opposite end of the tablet, at which is formed a cavity Z for the
