So soon as the skin is divided, the ether begins to exert on the nervous filaments the double action of cold and of etherization : so that the narcotism can be extended deeply to any desired extent. Pure rectified ether used in this manner is entirely negative ; it causes no irritation, and may be applied to a deep wound, as I shall show, without any...
Pagina 261 - a special mineralization producing a bituminous matter instead of coal or lignite. This operation is not attributable to heat, nor of the nature of a distillation, but is due to chemical reactions at the ordinary temperature, and under the normal conditions of climate.
Pagina 199 - For the sick-room, free ventilation, when it can be secured, together with an even temperature, is all that can be required. " 2. For rapid deodorization and disinfection, chlorine is the most effective agent known. "3. For steady and continuous effect ozone is the best agent known. "4, In the absence of ozone, iodine exposed, in the solid form, to the air is the best.
