• The wound at once gave him some pain, like the sting of a wasp, as he described it, and in a few minutes he began to vomit. This continued until his stomach was emptied, when he still experienced violent retching. He then became deadly faint, and lay down. Dr Klein-schmidt described his appearance four hours later as that of a person in the last stage of collapse; skin cold, pulse nearly gone, respiration feeble, and pupils widely dilated, with great dimness of vision. The right hand and arm were fearfully swollen, of a grayish-black color, resembling gangrene. He passed a feverish night, but was much better Sunday. On Monday evening I found him nearly free from pain, though the arm was still swollen to nearly the size of a man's thigh. From this time he progressed rapidly towards recovery, and in less than a week was out, with his arm in a sling, 4.
