    VII. Morhid Action of the Rectum and Bladder, and of the Sphincters. 1171. There is a peculiar affection of the rectum and bladder in some nervous affections, of which the following- experiment affords both the type and illustration : if, in a turtle, after the removal of the tail and the posterior extremi- ties, with the rectum, and, of course, with a portion of the spinal marrow, water be forced into the intestine by means of Read's syringe, both the cloaca and the bladder are fully distended before any part of the fluid escapes through the sphincter; which it then does only on the use of much force, and hy jerhs. If, when the cloaca is distended, the integu- ments over it are stimulated, the water is propelled to a con- siderable distance. 1172. When the rectum or bladder is distended, the pa- tient feels a sudden call,- and the action of the expulsors is so energetic, or the power of the sphincters is so diminished, that, unless the call can be promptly obeyed, the fteces or urine escapes. See further, the close of § 1192. 1173. In tenesmus and strangury, the sphincter of the rectum and of the bladder is excited to undue contraction respectively. A ligature applied to hsemorrho'ids not uncom- monly induces spasmodic action of the cervix vesicas and retention of urine. In one case, calculus in the bulb of the urethra induced spasmodic stricture of the sphincter ani. All examples of morbid reflex action. VIII. Singtdar Action of the Thoracic and Ahdomhial Muscles. 1174. Case 16.—In an interesting case, it was observed that, whenever the rectum was more than usually fretted, the muscles of the thorax and abdomen were drawn into violent action, especially the serrati and the recti; the insertions of the former, and the divisions of the latter, were marked as we observe them in certain pictures and statues. 1175. I now beg to draw the attention of this Society to another subject,—the localization of the effects of certain remedies, if I may use this expression: R
