The author has searched the markets of the world for suitable apparatus for intestinal irrigation, so that he, as a specialist in this line and in anal and rectal diseases, could recommend it to his patients. None of the appliances to be had, however, quite answered the purpose he had in view. All of them had some drawbacks. Owing to this fact, after much experimentation he has invented an instrument that is herein fully described to show its serviceableness. Were this volume to be issued without this description, the author would be inundated with interrogatories concerning the best instrument to be employed by its readers, or whether the appliances they have on hand would answer the purpose. As the object of this book is practical, not literary, it is not out of place, the author thinks, to describe the invention and its unique serviceableness, as well as its special adaptability for the tri-daily employment of enemas. The instrument is known as “The Internal Fountain Bath for Home Treatment.” The following illustration gives a very good idea of its construction and merits: [Illustration: [Patented Dec. 31, 1901; Nov. 14, 1905.] Figures 18, 21, 22, and 23. 18, Reservoir; 21, hard rubber handle; 22, metal handle; 23, metal handle, hard rubber cone, and enema point; 19, lamp support; 20, lamp; 33, rubber tube and shut-off; 24, glass bottle; 27, hard rubber anal cone; 29, valve; 28, enema point; 25 and 26, recurrent douche points; 30, glass bottle; 31, hard rubber cone; 32, enema point. Figure 24, Page 120, illustrates the author’s rubber enema appliance, The Niagara Fountain Syringe, holding about two gallons of water.] The Internal and External Fountain Bath is an appliance that I have devised and supplied to my patients for many years with most satisfactory results in every particular. Several other enemata and recurrent douche instruments which I have used did not wholly meet the requirements in capacity or aseptic features; but long use of this apparatus in all the various bowel troubles has demonstrated, to me as well as to my students and patients, that the instrument is the best that can be made, perfectly meeting all the requirements essential for scientific results. _Features and Uses._
