Nausea and vomiting

In the afternoon, between 2 and 3, both boys were taken sick with violent vomiting and great prostration ; the substances vomited at first were yellow ; the vomiting lasted in one till 11, and in the other case till 8 P.M., but was not frequent during the latter part of the time. About 6 p.m., a physician was called and found both patients lying in bed, seeming to be very sick, faces very red ; they complained of great thirst, were restless, had no diarrhoea, complained of no pain. Up to this time they had been perfectly healthy. The treatment consisted in the administration of Calcined magnesia. On the following day the patients still had red and hot faces, were apathetic, but when questioned showed a knowledge of what was passing around them. The younger at this time had some diarrhoea, and towards noon convulsions, daring which the face became livid ; these convulsions became more frequent towards evening; the patient died at 9 the next morning. The elder’s face continued red; he was apathetic, almost soporous; the skin of the chest and abdomen was remarkably erythematous ; in the evening, temperature in the axilla 39.5°. The next day the pulse was irregular and intermittent ; temperature in the evening 39.6°. He was ordered subcutaneous injections ot Chinin, as swallowing was exceedingly difficult in spite of great thirst. On the next day there was a bad odor in the mouth, sopor, difficult swallowing; temperature 39.2°. On the next day, a very bad odor in the mouth, swallowing almost impossible, mind greatly confused. Death at 11 a.m.,1.
