I am a physician, residing in Gower Street, Bedford Square. In the beginning of December, 1854, I was suffering from a severe cold, and being unable to shake it off, went for a fortnight to the sea for change of air. I selected Bognor, because I had been in the habit of spending my holidays there for two or three years. I was lodging in the Steyne. Some few days after my arrival, I received a message requesting me to call and see a lady who was dangerously ill at a lodging in another part of the town. At first I declined to go, not wishing to interfere with the established practitioners of the place. A gentleman then called upon me, who gave the name of the Baron R**. He informed me that the lady in question was his wife, and that she was dangerously ill from the effects of a considerable quantity of emetic tartar, administered to her by the maid. He was very urgent with me to attend, saying that he was in the greatest anxiety about his wife, and that he could not in such a case sufficiently rely upon the skill of any country doctor. He pressed me so strongly, that I at length consented to accompany him to his lodgings. I found the patient in a very exhausted condition, and evidently suffering from the effects of some irritant poison. From what the Baron told me, the symptoms were much abated, but the purging still continued, accompanied with severe griping pains and profuse perspirations. I learned from the Baron that, being himself a good amateur chemist, and having accidentally discovered at the outset the origin of his wife's illness, he had so far treated her himself, rather than trust to the chance of a country physician. He described his treatment, which appeared to me perfectly correct. On becoming satisfied of the cause of the disturbance, he first promoted vomiting as much as possible by the exhibition of tepid water, and afterwards of warm water, with a small quantity of mustard. When no more food appeared to be left in the stomach, he then administered large quantities of a saturated infusion of green tea, of which he had a few pounds at hand for his own drinking, and, finally, at the time of my arrival was exhibiting considerable doses of decoction of Peruvian bark: both which remedies are recommended by Professor Taylor in cases of antimonial poisoning. Their action left no doubt on my mind as to the origin of the symptoms; but by desire of the Baron I proceeded to analyse with him portions of the vomited and excreted matter, as also a portion of the arrow-root in which the tartarised antimony was supposed to have been administered. To all of these we together applied the usual tests,--viz., nitric acid, ferrocyanide of potassium, and hydrosulphuret of ammonia,--and succeeded in ascertaining beyond doubt the presence of antimony in all three. The quantity, however, appears to have been small. So far as we could ascertain, there could not have been more than one, or at
