opening in the intestine, which was made about two inches in length, and gradually pushed the intus-suscepted part back from the right to the left side, whilst I gently drew that part of the intestine which contained the intus-susceptio towards me. By this means I fortunately succeeded in unfolding the tangled intestine, which amounted to two feet in length. There was not the slightest trace of inflammation, nor any thing unnatural to be discovered in the part; there was merely a round worm, which was situated in the upper part of the intus-susceptio. The intestine was brought together by means of six spiral stitches, after the manner of the glover's suture, and the end of the silk was allowed to hang out of the external wound in the abdomen." The sutures were removed on the 8th day. On the 14th day, the man was cured, and continues well up to the date of the account. ARTICLE XI.--_An Inquiry into the Nature and Treatment of Diabetes, Calculus, and other Affections of the Urinary Organs._ By WILLIAM PROUT, M. D., F. R. S. _From the second London Edition, published in 1825; with Notes and Additions_, by S. COLHOUN, M.D. Philadelphia, Towar & Hogan, 1826; pp. 308. A very acceptable service has been done to the medical profession in this country, by the present republication of Dr. PROUT'S work on affections of the urinary organs. The American physician will now have it in his power, at a reasonable cost, to possess one of the best treatises on this interesting subject. From the known accuracy of Dr. PROUT as a chemist, and his reputation as an accurate observer of nature, much new light was naturally expected as the result of his observations. Nor indeed have these high expectations been disappointed. After a careful perusal of his work, we have formed the highest opinion of his powers, both as an original thinker, and experimental inquirer. Dr. PROUT begins his treatise with some introductory remarks on the composition of the urine, and on urinary derangements generally. After giving a comparative tabular view of the composition of the blood, and healthy and diseased urine, he proceeds to notice in succession, their principal constituents. As albuminous urine is of frequent occurrence in dropsical complaints, and its presence regulates in some degree the practice proper to be pursued, the following characters, given to it by Dr. PROUT, should be well understood.
