Simple fracture of the humerus, Gilbert tells us, is to be reduced (_ad proprium locum reducator_) at once by grasping the arm above and below the seat of fracture and exercising gentle and gradual extension and compression. Then four pieces of lint wet in egg-albumen are to be placed around the arm on all sides, a bandage, four fingers wide, also moistened in albumen is to be snugly applied, another dry bandage placed above this, and finally splints fastened in position by cords. This dressing is to remain undisturbed for three days, and then renewed every third day for nine days. After the ninth day a _strictura_ (cast, apparatus immobile?) is to be prepared and firmly applied with splints and a bandage, and the patient is to be cautioned not to bear any weight upon the injured arm (_ne infirmus se super illud appodiet_?). The fracture is then left until it is believed that consolidation has occurred. If, however, it is found that swelling is occasioned by the cast (_ex strictorio_?), the latter should be removed, and the arm well bathed in warm water containing mallowae and other emollients and thoroughly cleansed. If the bone seems to be well consolidated, it should be rubbed with an ointment of _dialthea_ or the _unguentum marciation_, after which the splints and bandage are to be reapplied. If, however, it is found that the bone is not well consolidated, the cast should be replaced in the original manner, until consolidation is accomplished. If erysipelas results from the dressings, it is to be treated in the ordinary manner. During the entire treatment potions of nasturtium seeds, _pes columbini_ (crowfoot) and other "consolidatives" are to be administered diligently. If the fracture is compound, any loose fragments of bone are to be removed, the fracture reduced as before, and similar dressings applied, perforated, however, over the wound in the soft parts. In fracture of the ribs (_flexura costi_) Gilbert recommends a somewhat novel plan for the replacement of the displaced bone. Having put the patient in a bath, the physician rubs his hands well with honey, turpentine, pitch or bird-lime (_visco_), applies his sticky palms over the displaced ribs, and gradually raises them to their normal position. He also says (f. 183a), the application of a dry cup (_cuffa vero cum igne_?) over the displaced rib is a convenient method for raising it into position. Of fractures of the forearm Gilbert simply says that they are to be recognized by the touch and a comparison of the injured with the sound arm. They should be diligently fomented, extension made if necessary, and then treated like other fractures.
