development of science and philosophy. Anyone who recalls, however, the history of Spanish intellectual influence in the Roman Empire, as we have traced it at the beginning of this chapter, will appreciate how favorable conditions were in Spain for the fostering of intellectual development. With the disturbances that had come from political strife and the invasion of the barbarians in Italy, Spain had undoubtedly come to hold the primacy in the intellectual life of Europe at the time when the Arabs took possession of the peninsula. ABULCASIS The most important of the Arabian surgeons of the Middle Ages is Albucasis or Abulcasis, also Abulkasim, who was born near Cordova, in Spain. The exact year of his birth is not known, but he flourished in the second half of the tenth century. He is said to have lived to the age of 101. The name of his principal work, which embraces the whole of medicine, is "Altasrif," or "Tesrif," which has been translated " The Miscellany." Most of what he has to say about medical matters is taken from Rhazes. His work on surgery, however, in three books, represents his special contribution to the medical sciences. It contains a number of illustrations of instruments, and is the first illustrated medical book that has come to us. It was translated into Latin, and was studied very faithfully by all the surgeons of the Middle Ages. Guy de Chauliac has quoted Albucasis about two hundred times in his "Chirurgia Magna." Even as late as the be ginning of the sixteenth century Fabricius de Acquapendente, the teacher of Harvey, confessed that he owed most to three great medical writers, Celsus (first century), Paul of Ægina (seventh century), and Abulcasis (tenth century). Abulcasis insisted that for successful surgery a detailed knowledge of anatomy was, above all, necessary. He said that the reason why surgery had declined in his day was that physicians did not know their anatomy. The art of medicine, he added further, required much time. Unfortunately, to quote Hippocrates, there are many who are physicians in name only, and not in fact, especially in what regards surgery. He gives some examples of surgical mistakes made by his professional brethren that were particularly called to his attention. They are the perennially familiar instances of ignorance causing death because surgeons were tempted to operate too extensively. His description of the procedure necessary to stop an artery from bleeding is an interesting example of his method of teaching the practical technique of surgery. Apply the finger promptly upon the opening of the vessel and press until the blood is arrested. Having heated a cautery of the appropriate size, take the finger away rapidly and touch the cautery at once to the end of the artery until the blood stops. If the spurting blood should cool the cautery, take another. There should be several ready for the purpose. Take care, he says, not to cauterize the nerves in the neighborhood, for this will add a new ailment to the patient's affection. There are only four ways of arresting arterial hemorrhage. First, by cautery; second, by division of the artery, when that is not complete-for then the extremities contract and the blood clots-or by a ligature, or by the application of substances which arrest blood flow, aided by a compressive bandage. Other means are inefficient, and seldom and, at most, accidentally successful. His instruction for first aid to the injured in case of hemorrhage in the absence of the physician, is to apply pressure directly upon the wound itself. The development of the surgical specialties among the Arabs is particularly interesting. Abulcasis has much to say about nasal polyps. He divided them into three classes: (1) cancerous, (2) those with a number of feet, and (3) those that are soft and not living,-these latter, he says, are neither malignant nor difficult to treat. He recommends the use of a hook for their removal, or a snare for those that cannot be removed with that instrument. His instructions for the removal of objects from the external ear are interestingly practical. He advises the use of bird lime on the end of a sound to which objects will cling, or, where they are smaller, suction through a silver or copper canula. Hooks and pincettes are also suggested. Insects should be removed with a hook, or with a canula, or, having been killed by warm oil, removed by means of a syringe. Some of his observations with regard to genito-urinary surgery are quite as interesting. He even treated congenital anomalies. He suggests cutting of the meatus when narrowed, dilatation of strictures with lead sounds, and even suggests plans of operations to improve the condition in hypo spadias. He gives the signs for differentiation between epitheliomata and condylomata, and distinguishes various forms of ulceration of the penis. Abulcasis discusses varicose veins in very much the same spirit as a modern surgeon does. They occur particularly in people who work much on their feet, and especially who have to carry heavy burdens. They should not be operated on unless they produce great discomfort, and make it impossible for the sufferer to make his living. They may be operated on by means of incision or extirpation. Incision consists of cutting the veins at two or three places when they have been made prominent by means of tight bandages around the limb. The blood should be allowed to flow freely out of the cut ends, and then a bandage applied. For extirpation, the skin having been shaved beforehand, the vein should be made prominent, and then carefully laid bare. When freed from all adhesions, it should be lifted out on a hook, and either completely extirpated or several rather long pieces removed. He lays a good deal of stress on the necessity for freeing the vein thoroughly and lifting it well out of tissues before incising it. In old cases special care must be taken not to tear the vein. Minute details of technique are often found in these old authors. Abulcasis, for instance, treats of adherent fingers with up-to-date completeness. They can occur either congenitally or from injury, as, for instance, burning. They should be separated, and then separation maintained by means of bandages or by the insertion between them of a thin lead plate, which prevents their readhesion. Adhesions of the fingers with the palm of the hand, which Abulcasis has also seen, should be treated the same way. At times there is surprise at finding some rare lesion treated with modern technique, and a hint at least of our modern apparatus. Fracture of the pubic arch, for instance, is described in Abulcasis quite as if he had had definite experience with it. When this occurs in a woman, the reposition of the bone is often greatly facilitated by a cotton tampon in the vagina. This tampon must be removed at every urination. There is another way, however, of better securing the same purpose of counterpressure. One may take a sheep's bladder into the orifice of which a tube is fastened. One should introduce the bladder into the vagina, and then blow strongly through the tube, until the bladder becomes swollen and fills up the vaginal cavity. The fracture will, as a rule, then be readily reduced. Here is, of course, not alone the first hint of the colpeurynter, but a very practical form of the apparatus complete. Old-time physicians used the bladders of animals very generally for nearly all the medical purposes for which we now use rubber bags. AVICENNA Undoubtedly the most important of Abulcasis' contemporaries is the famous physician whose Arabic name, Ibn Sina, was transformed into Avicenna. He was born toward the end of the tenth century in the Persian province of Chorasan, at the height of Arabian influence, and is sometimes spoken |
