The following case is recorded in the memoirs of the Academy of Sciences, by M. Homberg. A woman, of about thirty-five, became subject to a headach, which at times was so violent, that it drove her out of her senses, making her sometimes stupid and foolish, at other times raving and furious. The seat of the pain was in the forehead, and over the eyes, which were inflamed, and looked exceedingly red and sparkling; and the most violent fits of it were attended with nausea and vomiting. In the time of the fits, she could take no food; but at all others she had a very good appetite. M. Homberg had in vain attempted her cure for three years, with all kinds of medicines: only opium succeeded; and that but little, all its effect being only to take off the pain for a few hours. The redness of her eyes was always the sign of an approaching fit. One night, feeling a fit coming on, she went to .ie down upon the bed; but first walked up to the glass with the candle in her hand, to see how her eyes looked: in observing this, the candle set fire to her cap; and as she was alone, her head was terribly burnt before the fire could be extinguished. M. Homberg was sent for, and ordered bleeding and proper dressings: but the expected fit this night never came on; the pain of the burning wore off by degrees; and the patient found herself from that hour cured of the headach, which had never once returned in four years after; such being the time when the account was communicated.

Another case, not less remarkable, was communicated to Homberg by a physician at Bruges. A woman, who for several years had her legs and thighs swelled in an extraordinary manner, found some relief from rubbing them before the fire with brandy every morning and evening. One evening, the brandy she had rubbed herself with took fire, and slightly burnt her. She applied some brandy to her burn; and in the night all the water with which the afflicted parts were swelled, was entirely discharged, and the swelling did not again return.
