"It is necessary that a surgeon should have a temperate and moderate disposition. That he should have well-formed hands, long slender fingers, a strong body, not inclined to tremble, and with all his members trained to the capable fulfilment of the wishes of his mind. He should be well grounded in natural science, and should know not only medicine but every part of philosophy; should know logic well, so as to be able to understand what is written; to talk properly, and to support what he has to say by good reasons." He suggests that it would be well for the surgeon to have spent some time teaching grammar and dialectics and rhetoric, especially if he is to teach others in surgery, for this practice will add greatly to his teaching power. (What a desideratum for the modern time is thus outlined!) Some of his expressions might well be repeated to young surgeons in the modern time. "The surgeon should not love difficult cases, and should not allow himself to be tempted to undertake those that are desperate. He should help the poor as far as he can, but he should not hesitate to ask for good fees from the rich." Lanfranc was himself a scholar well read in the literature of his profession, but who had well digested his reading. He quotes altogether more than a score of writers on surgery who had preceded him, and evidently was thoroughly familiar with general surgical literature. He is a particular favourite of Gurlt, the German historian of surgery, who has devoted more than twenty-five closely printed large octavo pages to the discussion of this old Paris professor and his work. Lanfranc's discussion of wounds of nerves is of itself sufficient to show the character of his work. Many generations after his time have used the word nerves for tendons, and mistaken the function of these two structures, but Lanfranc distinguished very clearly between them. He declared that since the nerves are instruments of sense and motion, wounds of them should be carefully treated, especially as the sensitiveness of these structures is likely to cause the patient much subsequent pain if they are neglected. Longitudinal wounds of nerves are much less dangerous than those across them. When a nerve is completely divided in cross section Lanfranc was of the opinion, though Theodoric and some others were opposed to it, that the nerve ends should be stitched together. He says that the suture insures the reintegration of the nerve much better. Besides, after this operation the restoration of the usefulness of the member is more assured and is commonly more complete.
