Another method, sometimes employed by progressive physicians, consists in using, in connection with the fountain syringe, a tube from eighteen to twenty-four inches in length, made of a firm but flexible variety of rubber. This was introduced (its entire length) into the body, the theory being that it was necessary to get behind the impacted mass and force it out ahead of the water, which was theoretically correct, but in practice found sadly wanting. In the first place, the opening in the eye of the tube became clogged with the fæcal matter, and, secondly, with the double tube employed for the return flow, the opening was too small to allow of the passage of solid substances. The introduction of the catheter is a process requiring considerable skill, and a perfect acquaintance with the anatomy of the parts, so that personal use of it is practically impossible, or, at least, attended with considerable danger. An examination of the diagram of the digestive apparatus at the beginning of the book will enable the reader to understand the difficulties attending its introduction, since it has to pass the sigmoid flexure (No. 12), and the splenic flexure--that angle of the colon where the transverse portion turns to descend. With such a tortuous road to travel, the risk of injury to the sensitive mucous membrane is excessive--hence this instrument should never be used by the patient upon himself. The author, however, felt that there must be an easier and more effective method of irrigating that important organ--the colon--and one unattended with any risk, and determined, if possible, to devise some better way. After much patient and tireless experimenting he invented and perfected the “J. B. L. Cascade,” a mechanical appliance which completely rids the process of all its objectionable features, and enables young and old, weak and strong, to use the treatment without the possibility of danger. It achieves the desired result far more effectively than any other known apparatus, with the least possible inconvenience to the patient, and yet so gently and easily that the operation, so far from being distressing or disagreeable, becomes a positive gratification. The letters J. B. L. are the initials of the words Joy, Beauty, Life, which aptly indicate its purpose and effects, for we confidently claim that its use will infallibly confer these three great blessings, it being the one safe and sanative method of regaining and preserving health. Without health there is no joy in life, and perfect beauty cannot possibly exist, while with health life becomes indeed worth living.
