    Laforgue's Method of Applying Medicinal Fowders. handle if it is hollow, or into exterior grooves if it is solid. The hag is filled with medicinal powder through an exterior hole made in the handle and communicating with the interior of the hag, and it is caused to pass into the required cavity hy means of the handle. It is then only necessary to draw a ring or noh at the end of the wire and the seam 5 threads or wires will slide in the holes made for their passage and the valves are set free. The straps from the top being drawn hy the wire or thread will open the hag, folding hack exteriorly on each side the membrane or other material of which the valves are made, leaving the powder at the part required. 10 Having thus stated the nature of my Invention I will proceed to describe the best way I am acquainted with for carrying the same into effect hy reference to the accompanying Drawing, in which Figures 1, 2, and 3 show the hag, which hy preference is of a conico-cylindrical form, and made of goldbeater’s skin; any other suitably flexible skin 15 or material may he employed for its manufacture, and consisting of two valves. Each valve A is united to the other hy very fine double wire B, B; it is also furnished with a double ribbon or strap B1, which is glued or pasted thereto. The bag being thus made is turned to place the seam inside, and when in the position shewn by Figure 3 its edges 20 are glued to the opening C, C, of the hollow handle, Figure 4, which I make by preference of cardboard, although it may also be made of wood, bone, india-rubber, or other suitable material. The upper part of the handle is shewn in section at Figure 5; it is divided into two parts by the partition or diaphragm 0. A is the opening for charging the interior 25 of the bag. The openings B, B, Figure 4, serve for the passage of the ribbons or straps C, C, Figure 3; these ribbons or straps are turned over, and are attached to the ring A of a metallic rod, Figure 8, which is furnished at its other extremity with a larger ring B, and which lodges in the interior of the handle. The wires with which the bag is 30 sewn are also fixed to the part A of the rod, Figure 8, so that by pulling the ring B the wires forming the seam may be completely drawn and the bag be undone before the ribbons or straps fixed to the top of the two valves of the bag are moved, and the bag divided in two. The bag may be goffered or steeped in a fatty matter, such as a mixture of wax 35 and oil, to give it consistency. Instead of the wire shewn at Figure 8, a cord. Figure 9, may be used. A small ferrule. Figures 6 and 7, may
