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. 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.
