The instrument is attached to the reservoir (Figure 18) by a soft-rubber tube. In the cone-shaped piece of hard rubber (Figure 27) is a hard-rubber stop-cock or valve (Figure 29), and by turning the handle sidewise the valve is opened to let the water escape from the bowels into the toilet basin. When sufficient water, at from one hundred and twenty to one hundred and thirty-five degrees temperature, has entered the bowels, allow it to remain for ten minutes, then permit it to escape by opening the valve; then close it and allow more hot water to flow in and remain for five or ten minutes and again allow it to escape through the rectal point, repeating the inflow and outflow every five or ten minutes for an hour or more without removing the anal point from the rectum during the whole time of treatment. After a few trials it will be found that the hot-water treatment can be accomplished without withdrawing the point. Rectal Points for recurrent douche are of two sizes (Nos. 25 and 26). The larger one (No. 25) requires a plug to be introduced through the cone-shaped external anal support and rectal point, to make its introduction into the rectum easy, after which the plug is withdrawn and the hot-water treatment begun. The bore of the rectal points cannot become clogged by the presence of feces, mucus or membranous shreds or casts, which are usually brought away by the hot-water treatment. At no time during the treatment can the point become stopped up, the size being sufficient to insure a proper inflow and outflow. And the instrument can be easily cleaned. Near the attachment of the soft-rubber tube is a glass reservoir (Figure 24), for the use of oils with the enema or the hot-water treatment; it is detachable. A valve regulates the outflow of oil from the pressure of water in the reservoir, as it passes into the bowels. We are enabled thus to treat by double medication as it were, a chronic disease of the intestines and its symptoms--that is, intestines that have been long neglected or maltreated through lack of proper diagnosis, or by all sorts of chemical compounds from above, through mouth and stomach.
