Saliceto’s work on surgery is of a thoroughly practical character and reveals the author to have been a born surgeon.[62] In addition to the “_Cyrurgia_,” which was first printed in Piacenza 1476 A. D., he wrote a treatise which bears the title “_Summa conservationis et curationis_” (printed first in Piacenza in 1475). The “Surgery” is divided into five books, preceded by a short chapter on general methods, etc. Book I. is devoted to affections of the cranium, eruptions on the head, eye diseases, ear diseases (snaring of ear polypi), nasal polypi, abscesses in the axilla, affections of the mammary gland, tumors in different parts of the body, venereal lesions in the groin, and a long list of other surgical maladies. Book II. describes wounds of all sorts, including those produced by arrows (with reports of cases), penetrating wounds of the chest and abdomen (with instructions about sewing both longitudinal and transverse wounds of the intestine), etc. Under the head of penetrating wounds of nerves (declared by the author to be very dangerous), Saliceto recommends enlargement of the wound, the application of oil, and the employment of opium or hyoscyamus to quiet the pain. Book III. treats the subject of fractures and dislocations in a most thorough manner. Mention is made of the crepitation noise heard in fractures (_sonitus ossis fracti_) and a warning is given not to apply the bandages too tightly and to be careful to change the dressings every three or four days. The instructions given with regard to the reduction of dislocations are said by Neuburger to be most sensible. Book IV. contains such anatomical descriptions as may be helpful to the practical surgeon. From these, however, it is evident that the writer had never dissected the human cadaver. Book V. is devoted to the subject of cauterizing and to the consideration of those remedial agents which are commonly employed in surgery. The instruments used for cauterizing purposes were made of different metals, gold or silver being preferred for the more delicate ones, and brass and iron for the others. Immediately after the cauterization it was customary to apply butter, or the fat of some animal, or oil scented with roses, to the burned part.
