The following symptoms were produced by the sting of a common yellow wasp. I send you a minute of the case.

Master — , aged 16, sickly, has had what has been termed scrofula ever since he was born. Has had caries of the bones, severe rheumatism and suppurating glands. For a few years he has been better and has taken exercise and has been able to work some.

August 4th, he was at work painting, when in disturbing a “hornets nest” one of the yellow jackets as they are called, stung him on the hand. In less than an hour his hand became greatly swollen and painful, which was followed immediately by swelling and puffiness of the lower lids and scrotum, together with the integument of the penis. The parts were swollen more than twice their usual she. Almost immediately the skin on the abdomen, anus, legs, neck and nearly all the back turned purple (almost black), which was followed by an eruption of urticaria which completely covered the body. Two or three hours after the sting, his eyes were nearly closed and this dark color and urticaria were fully developed. They all continued for about twenty four hours, when they gradually disappeared in the order in which they came on. He took Apis 0, one drop every four hours.

Yours respectfully, C. W. BOYCE, M.D.

Auburn, N. Y., August 9th, 1862.
