20. _Chloride of Lime in cases of Burns_.—The good effect of chloride of lime in cases of burns is confirmed by the experience of M. Lisfranc. He has applied it in many cases of that kind, sometimes immediately after the accident, sometimes after the application of emollient cataplasms. Lint is moistened in a solution more or less strong of chloride of lime, and then applied to the place, being covered over with waxed cloth. The cure has been singularly hastened under its influence and in one case where almost the whole of the lower limbs, the arms and face, had been burnt, the use of the chloride recovered the patient from the stupor into which he had fallen at the end of four days, and a perfect recovery was effected two months after the accident.—_Bull. Univ_., C. xi. 77. [p232] 21. _Cure of Nasal Polypi_.—Dr. Primus of Babenhausen asserts, that the saffronised tincture of opium (of the Prussian Pharmacopœia) possesses the property of gradually destroying nasal polypi when applied to them. Certain cures, which have been thus effected, have already been published, and a striking one occurred in January, 1826. A man, 46 years of age, had one in each nostril. The tincture was applied several times a day to the bases of the polypi, by means of a small hair-brush or lint roll. In eight days the tumours had assumed a paler appearance, and lost a little in volume; a serous secretion from the nose, which had existed for a long time, was diminished, and the pituitary membrane had acquired a more lively tint, as if in a sub-inflammatory state. The application was continued, the tumours continued to decrease, and at the end of three weeks had entirely disappeared.—_Mediz. Chirurg. Zeitung_, 1826, p. 13. 22. _Bite of the Viper_.—M. Jacopo Sacchi, of Barzio in Valsasina, having had occasion to take charge of some cases in which injury had been inflicted by the bite of a viper (Coluber Berus), transferred his observations upon them into the hands of Professor Paletta. From these it appears that ammonia, recommended by Dr. Mangili, in 1813, although an excellent remedy in many cases, is by no means sufficient in all, but must occasionally be seconded by every possible means. Although sometimes nature alone has power sufficient to overcome the bite of a viper, yet, at other times, the injury is so great and sudden as to resemble the effects of hydrocyanic acid. In these cases he recommends that the patient should be put into a hot bed covered with woollen clothes, and the most powerful sudorifics with some tonics administered internally. Friction should be applied all over the body, and at the same time the wounds are to be enlarged, cupping-glasses applied, and tow, dipped in ammonia, applied to the spot.
