This scientific device can be used without assistance. It has one feature moreover, that renders it unique among rectal appliances, namely that you may take a number of rapid injections without changing your seat. You may inject a small quantity of water (from eight to twelve ounces), and expel it immediately; then you may follow with a larger amount (from one to three pints), and expel that also, then in the same manner flush the colon. A complete internal bath may be effected in the same way by using three, four or more quarts of water. In this way, thorough depurating results may be obtained. The several preliminary injections of gradually increasing quantities of water free the lower bowel of feces, germs, and gases which otherwise might be forced by the flushing process backward into and along the colon. With the Internal Fountain Bath, unlike other syringes, it is not inconvenient to take preliminary injections before flushing the bowels. After the flushing the rectal and anal canals the bowels can be easily cleaned their entire length, as can also the integument about the anus and buttocks by letting the jet of water play on these parts to wash away any germs and other poisonous discharges. All the necessary movements of the anal point are easily made with the handle which projects between the limbs in front of the toilet seat. _Cleanliness._ The water reservoir is enameled white, both inside and out and free from poisonous substances. The enamel is not injured by the use of any germicidal remedies that may be placed in the water, or by the water being brought to a very high temperature to destroy bacterial poisons. Furthermore this enameled surface is easily cleaned, thus avoiding foulness of the reservoir from continued use. The glass medicine case and anal cone attached to the handle, as well as the anal point, are all detachable and easily cleaned, and the handle is of sufficient length to obviate soiling the hands and impregnating them with odors.
