    were in the middle third, and of these 41, or (JO per cent., died ; wliilst in the lower third the mortality out of GO cases was <?7, or 56 per cent. The size of the part removed and its proximity to the trunk have also con- siderable influence on the cause of death. Thus after the smaller amputations death occurs only in unhealthy states of the constitution, or from the occur- rence of erysipelas, or of some other infective process originating in the wound. In the larger amputations in addition to these causes of death, shock is fie- quently fatal, often aggravated by lossof-blood before or during the operation. The larger the vessels divided the more likely is secondary haemorrhage to occur. 2. The Part of the Bone that is sawn through may influence the result. WhencA^er the medullary canal is opened, if the patient be exposed to bad hygienic surroundings, and putrefaction of the discharges be not prevented, there is danger of septic suppuration taking place in the medulla, a condition very frequently followed by pytemia. Amputations through the cancellous ends of long bones are comparatively free from this danger, and consequently show a lower mortality. In disarticulations this complication can hardly occur. 3. The mortality resulting from amputations is influenced to a great extent by the Cause for which the operation is performed, being far greater in corre- sponding parts after injury than after disease. Tl.e fore-arm and ankle, how- ever, seem to be exceptions to this rule, for the reason that amputations in these regions cause little shock, and the vessels divided are small, and secondary haemorrhage is rare. Thus two important causes of death are eliminated, and a healthy patient usually recovers. When the amputation is performed for disease, however, it is most commonly in cases of tuberculous caries, in vrhich, owing to the general condition, other means have failed to cure. The following table gives the result of numerous cases in civil practice, collected from various sources. (See note, p. 86.) SEAT. Diaeasc. CASES. DEATHS. PER CENT. CASES. DEATHS. PER CENT.
