It has been even proposed to suspend or destroy the function of the nervous system for a time, by the employment of the Wourali poison, keeping up at the same time respiration by artificial means, under the expectation that thus the impression on the system might be got over. The morbid appearances usually observed after death are marks of inflammation of the pharynx and air-passages, and of the mucous surface of the stomach and intestines. It is evident that the disease ought to be prevented if possible, and for its prevention the most efficient measure is timely excision of the affected parts; and they should be cut out a long period before the constitutional affection comes on: when excision is dangerous, or wholly impracticable, and when the patient does not apply soon after the accident, the injured parts may be destroyed by some active caustic, as the potassa fusa. The nitrate of silver has been strongly recommended and extensively employed by Mr. Youatt, whose experience in this disease is very great. This application should scarcely be trusted to alone. The removal of parts wounded by snakes, even after violent symptoms have appeared, has proved successful, ammonia having been at the same time administered internally. In some instances, arsenic has been found efficacious when given in large doses, and frequently repeated.[23] Wounds received during dissection occasionally have unpleasant consequences from the absorption of animal matter. The absorbents leading from the wounded part become swelled and painful, and in slight cases there are shivering and general indisposition for some days. The more violent symptoms arise from examining bodies which are rather recent, and in which putrefaction is just commencing, and very frequently from inspecting the bodies of females who have died of puerperal diseases. The absorption may take place from punctures made by scissors, the point of a knife, or spiculæ of bone, or from old scratches, or chops by the side of the nail or on the hand. There is little or no danger from an open and bleeding wound, as by the flow of blood the part is completely cleaned; it is generally from slight punctures that untoward symptoms need be apprehended. Effects similar to those resulting from wounds in dissection often occur in nurses and others who have pricked themselves with pins while washing foul clothes, or from handling poultices or dressings removed from bad, putrid, or sloughing surfaces. The symptoms already mentioned are soon followed by others more severe: shivering continues, and the patient is seized with vomiting; the part affected, and often the greater part of the arm, becomes red and much swollen; the cellular tissue is infiltrated with serum often dark and putrescent, abscesses form at various points along the limb to the axilla, and purulent matter is diffused throughout the unhealthy cellular tissue, which in many instances sloughs, and gives rise to extensive sores.
