H. K., aged 22 years, previous to March 6, 1904, never had any stomach symptoms. He occasionally used alcoholic stimulants. For his supper the evening of March 5 he ate a quantity of baked beans, and at 1 a. m., March 6, he indulged in another meal of baked beans. The second meal did not taste right and he was taken sick and vomited in a few minutes after eating it. This was followed by severe abdominal pain, and pain in both shoulders. I saw him two hours later, when he was having considerable pain, with mucus vomiting. An enema that had been administered failed to secure an action of the bowels. He was tender all over the abdomen; pulse and temperature were normal. Dr. W. P. Bowers saw the patient with me, but a positive diagnosis could not be made. Exploration was urged, and assented to by the family.
