"G.K..., a soldier aged 21 years, thin, tall, and who during his infancy had been subject to ascarides, has occasionally voided during more than 10 years past, portions of taenia. He had used several purgative medicines, by which several yards of this worm had been expelled; but annoyed with so many attempts at obtaining its total expulsion, he had ceased, three years before, the use of all sorts of anthelmintics. But the phenomena resulting from the presence of the animal being aggravated, the patient applied for advice to Dr. DE POMMER, who found him labouring under the following symptoms:--Frequent pain in the abdomen, and especially in the umbilical region, accompanied with a sense of burning heat, and alternate distension and depression of the abdomen. Appetite sometimes keener than in health; at others nearly lost. In the morning before breakfast, the patient was seized with extraordinary weakness, and general uneasiness, accompanied with trembling of the limbs, ineffectual attempts to vomit, a sense of constriction in the throat, and a profuse salivation. All these symptoms disappeared after K... had taken food; but reappeared two hours after. Milk and farinaceous aliments were the only articles of which he could make use without an aggravation of his disease. The pulse was febrile; sleep good, but attended with dreams. The pupils were in the natural state. From the symptoms, and from the history of the case, Dr. P. was induced to make use of the oil of turpentine in the following manner. The patient was ordered in the morning, before breakfast, three table spoonsfuls of the remedy, at half an hour's interval. The first doses produced only a few borborygma. Two more table spoonfuls occasioned a vomiting of mucous matter. Three more table spoonfuls were exhibited, and followed by a stool of solid faeces, mixed with which were five small pieces of taenia. The patient not finding himself incommoded, took in the space of an hour, three more table spoonfuls of the remedy, after which he experienced some pain in the head, and vomited about one pint of bilious liquid. An hour after, the same quantity of the medicine was taken, and followed again by vomiting, but after a repose of half an hour K... discharged, per anum, firm and greenish faeces, and with them five ells of taenia. The urine discharged had the smell of violets. He again took a few spoonfuls of the vermifuge, which were not followed, however, with any faecal discharge, and only with some vomiting of mucus, and slight vertigo. In the afternoon the patient felt well, and experienced a great appetite, in which he indulged. From this moment he recovered, and has ever since enjoyed good health. The quantity of the remedy used was six ounces."
