Case

of poisoning by oxalic acid; recovery. Poisoning by sulphate of copper ; symptoms and treatment. Convulsions from teething ; effect of the application of cold; the warmbath.

DR. ToDD remarked, first, that in his last clinical lecture* he had called the attention of the students to a case of poisoning by oxalic acid ; another case had since occurred precisely similar. The young woman who was the subject of it bought the acid, as she stated, at a medical man’s shop, and swallowed it in a wineglassful of water ; the quantity was a pennyworth ; it burned her throat severely, and tasted exceedingly sour. For three-quarters of an hour after having taken the poison she suffered intensely from

violent pain in the throat, and griping pains in the belly, which quite drew her double, violenttremors, intense frontal headach ; she felt very hot, and had pain in swallowing, and burning in the course of the oesophagus. In an hour from the time of taking the poison she had medical assistance, and two or three pints of chalk mixture were administered : she was shortly afterwards admitted into the hospital (January 30th), still complaining of severe abdominal pain, but not showing any signs of collapse ; she got an emetic of sulphate of zinc, and afterwards chalk mixture, whilst the vomiting was encouraged by copious draughts of hot water. This woman had no bad symptom : on the night of the 30th she had cramps in the legs, and next day suffered from muscular soreness in the epigastric and lumbar regions, which, doubtless, were only the effects of the efforts of vomiting.

POISONING BY SULPHATE OF COPPER.

It was so important for the medical practitioner to be always prepared in cases of emergency, that Dr. Todd thought it well briefly to notice another case of poisoning which was admitted into the hospital a few days before the last. A young woman, aged eighteen, was admitted on the 24th of January on account of having swallowed a solution of what she called copperas ; on inquiry it was found to be blue copperas, or sulphate of copper. In this case the after-symptoms only had to be treated ; she had swallowed the poison on the 18th, a week before ; five minutes afterwards she vomited; she then took a large quantity of salt and water, by which the vomiting was considerably promoted ; her throat became very painful and felt burnt, and the abdomen became swollen, tender, and painful ; she passed a good night. Next day she had constant pain in the region of the stomach, and vomited everything, solid and liquid; she had also some diarrhoea. The vomiting, diarrhoea, and abdominal pain, continued till the day of her admission. On admission she was suffering chiefly from exhaustion ; she had some pain in the abdomen, an unpleasant coppery taste in the mouth, nausea, without vomiting, and dial" rhoea ; tongue white and furred; general exsanguined state of the surface ; pulse 150. One-third of a grain of hydrochlorate of morphia was given directly, and an effervescing draught, containing five minims of tincture of opium, every three hours; to have also a common enema,containing twenty 4rops of tincture of opium. The opium readily controlled the diarrhoea, the taste in the mouth became less distinct, the pain in the abdomen disappeared, and she was able to take wine and beef-tea. On the 27th she completely recovered her appetite, and lost all pain, except some headach. She was now ordered middle diet, and one grain of sulphate of quinine three times a-day. In this case there were some of the irritant effects of the sulphate of copper. This poison, said the lecturer, acted very much in the same way as arsenic and corrosive

sublimate ; it irritated, inflamed, and killed the mucous membrane of the oesophagus and stomach with which it came in contact; and it not only produced these local effects, but likewise, and especially when taken in a large dose, or in a concentrated form, it affected the nervous system, causing insensibility, convulsions, tetanic spasms, or
