SlK,?Oxygen gas ami oxygenated water, &c., being found of late to liave remarkable antiseptic properties, it is to be expected that they might prove of great service in the treatment of Plague. I beg, therefore, to request those having Plague cases under them to have the following plan of treatment given a fair trial: in place of Liquor Hydrarg. Perchloride, Carbolic Acid and other antiseptics already in use. 1. Oxygen gas, to be inhaled, at frequent intervals. 2. Internal use of oxygenated water, permanganate of potash, or chlorate of potash ; to be given in small doses, frequently repeated, in addition to other symptomatic treatment.
