    Lavaters Improvements in Injection Bottles, <fyc. thereof. From these views it will be seen that the ordinary mouthpiece of wood or other material, which has heretofore been fixed in the neck of such a description of bottle, in order to receive the end of a clyster or other pipe, is dispensed with, and in place thereof the neck or mouthpiece of the bottle itself is made of greater substance, in order that, by the greater strength 5 thereof, the holding of the end of a clyster or such like pipe may be made more secure than when a wood or other mouthpiece is used to receive the end of a clyster or other pipe, as was formerly the case. The bottles, as here¬ tofore, are made of vulcanized or converted india-rubber, a is the elastic mouthpiece, and b a clyster pipe fitted therein, the hole or passage in the 10 mouthpiece being smaller in diameter than the exterior of the clyster pipe, so that when the end of the clyster pipe is forced in, the elastic mouth¬ piece embraces the same very strongly, and in such manner as to prevent the passage of the fluid in that direction when the bottle is pressed in with a view to force the fluid through the clyster pipe. In the Drawing the ordinary 15 form of clyster pipe is shewn, but, if preferred, the end may be made larger, and the mouthpiece or neck of the bottle also larger than that shewn, and made similar to those heretofore made when intended to receive and have fixed therein a mouthpiece of wood or other material, but in this case also the thickness or substance of the india-rubber is to be made of greater strength, 20 and sufficient to hold the end of the clyster or other pipe securely. Figure 3 shews a plan and section of a disc of india-rubber (by preference vulcanized or converted india-rubber) suitable for pneumatic apparatus for adhering to glass and other impermeable surfaces for which plain discs of india-rubber have heretofore been used. Figure 4 shews a plan and section 25 of another form of india-rubber disc; and I would state that the shape may be varied, but the circular or elliptical form is preferred; but in all cases they are to be made similar in respect to having their outer edges or parts thicker or of greater substance than the central parts, and they should also in all cases be made similar in respect to having tubular portions produced at the 30 centres, in order more securely to attach the end of the stem air-tight thereto. These india-rubber discs are formed in moulds, and retained therein during the process of vulcanizing or curing the same by hand, as is well understood, when making other articles of vulcanized or cured india-rubber in moulds. I would remark, that although it is preferred to employ india-rubber and 35 sulphur without the admixture of other matters, I do not confine myself thereto, as other substances may be combined therewith. Having thus described the nature of my Invention and the manner of performing the same, I would have it understood that what I claim is,—
