It is impossible to give any adequate idea of the thoroughly practical character of Rhazes' medical writing in a few lines, but it may suffice to say that there is scarcely any feature of modern medicine and surgery that he does not touch, and oftener than not his touch is sure and rational and frequently much better than the advice of successors long after him in the same matters. An example or two will suffice to illustrate this. In the treatment of nasal polyps he says that whenever drug treatment of these is not successful, they should be removed with a snare made of hair. For fall of the uvula he suggests gargles, but when these fail he advises resection and cauterization. Among the affections of the tongue he numbers abscess, fissure, ulcer, cancer, ranula, shortening of the ligaments, hypertrophy, erythema of the mucous membrane, and inflammatory swelling. In general his treatment of the upper respiratory tract is much farther advanced than we might think possible at this time. He advises tracheotomy whenever there is great difficulty of respiration, and describes how it should be done. After the dyspnea has passed the edges of the wound should be brought together with sutures. It is not surprising, then, to find that the treatment of fractures and luxations is eminently practical, and, indeed, on any subject that he touches he throws practical light. In the introduction to his edition of the works of Ambroise Pare, Malgaigne says that the first reference to a metal band in connection with trusses is to be found in Rhazes. Hernia was, of course, one of the serious ailments that, because of its superficial character, was rather well understood, and so it is not surprising to find that much of our modern treatment of it was anticipated. The manipulations for taxis, the use of a warm bath for the relaxation of the patient by means of heat and by putting the head and feet higher than the abdomen while in the bath, and the employment of various kinds of trusses to prevent strangulation of the hernia recur over and over again, in the authors of the Middle Ages. Many of the suggestions are to be found in the early Greek authors, but subsequent writers give a certain personal expression to them which shows how much they had learned by personal observation in the employment of various methods.
