    Tolhausen’s Improved Surgical Injecting Apparatus. and \ inch bore. This tube is tapped at A1, for receiving the metallic neck of the collapsible ball R ; at B1 there is a union for passing on the suction tube C1, D1. Near the upper end of said tube there is a branch for joining the lower end of the tube A, P, B, C. At its lower end this tube forms a valve box containing a spherical valve M1, of marble, or any other suitable 5 material, which allows the liquid to rise from the suction pipe C1, D1, into the tubes, but prevents the same from returning. The projections F1, G, are intended to limit the rise of the valve M1. Fourth, R is a hollow india-rubber ball, measuring about 10 inches in circumference, which is fastened on the end A1 of the tube A1, B1, in such 10 manner as to form a tight joint, as shewn on the Drawing. A piston or other pumping apparatus may be used instead of the elastic collapsible ball, but I generally prefer the latter, being more easily worked, and less liable to get out of order. • Fifth, C1, D1, is a flexible or india-rubber suction pipe of suitable length 15 and diameter, which at its upper end is passed on the union C1, thereby com¬ municating with the tube A1, Bl. At its lower end the tube carries a glass or porcelain suction cup, which dips into the liquid. Sixth, M, N, is a brass tap or cock, which fits into the tubular projection L on the plate D, E. An india-rubber pipe may be passed on the lower end of 20 the tap, as the case may require. Seventh, U1 is a small metallic thimble for closing up the orifice B1 of the tube A1, B1, as may be required in some cases. Eighth, X, Z, is a canula of the ordinary shape for clysters, which, by means of its end Y may be fitted on the tube A, B, C, the injector G, D, E, 25 having previously been removed. All the metallic parts above described are made of some alloy not subject to rapid oxidation, such as Britannia metal. The different part having been put together, as represented on the Drawing^ the apparatus is used in the following manner, for vaginal injections:—The 30 subject either cowers down, leaning her back against a support, or else seats herself on the edge of a low chair, in case the subject is in bed, she straddles her thighs, and a basin is placed under her seat, and another basin containing the injecting liquid is placed about 12 inches further in front. She then takes hold of the apparatus with her right hand, by placing the face of the 35 thumb against the concave part of the spur U, and the other fingers of the same hand in the concave portion of the tube, and introduces the mouth-piece or pap F, G, into the vulvo-vaginal orifice, taking care to exactly press and adapt the plate D, E, against the labiae, and during this operation the end
