Part I. of the _Chirurgia Parva_ mentions some of the characteristics which a surgeon should possess. He should, for example, have well-formed hands, with fingers that are long and slender; his body should be strong and firm in its movements; his hands and fingers should respond quickly to the workings of the mind; his mind should be of a subtle type; in character he should not be over-bold, but self-reliant and yet modest; he should have a good supply of common sense; he should be well-informed not only in medicine, but also in all the branches of philosophy; he should be a good logician; he should be familiar with the writings of medical authors; he should be virtuous and ethical; he should be trustworthy; he should not be avaricious nor envious; ... and, finally, he should be thoroughly familiar with all the diseases to which the human body is liable. In one place Lanfranchi refers to the fact that exposure to the air favors the production of pus in a wound. Among the methods which may be employed for arresting hemorrhage he mentions digital compression and ligaturing of the bleeding vessels. He recommends that a wounded individual should abstain from wine and from an over-nutritious diet. No attempt, he says, should be made to extirpate, with the knife or by means of the actual cautery, an ulcerated cancer, unless it appears probable that by such means complete destruction of the tumor may be effected. In traumatic tetanus dependent upon an injury of a tendon or nerve trunk he recommends complete division of the wounded structure. Part II. is devoted to the consideration of wounds of the different parts of the body, taken in regular order from the head to the feet. The descriptions, in each instance, are preceded by an adequate account of the region affected. In his discussion of fractures of the skull he speaks of the diagnostic value of the rough and jarring sound perceived by the patient when the physician taps with a rod upon the injured skull; and he also states that an aid to diagnosis may be derived from the fact that a person whose skull is fractured experiences pain at the seat of the injury when somebody passes the ends of his finger-nails along a string which the patient holds suspended between his teeth.[67] According to Neuburger the description which Lanfranchi gives of the various symptoms observed in cases of fracture of the skull is admirable. In the section relating to the treatment of such fractures he warns against the tendency to resort too readily to the use of the trephine, and expresses the belief that this instrument should be employed only when the fractured bone is depressed or when there is evidence of irritation of the dura mater.
