Fumigations. For foul barns and stables, take of
| Common salt, | 4 ounces. |
| Manganese, | 1 ounce and a half. |
Let these be well mixed, and placed in a shallow earthen vessel; then pour on the mixture, gradually, sulphuric acid, four ounces. The inhalation of the gas which arises from this mixture is highly injurious; therefore, as soon as the acid is poured on, all persons should leave the building, which should immediately be shut, and not opened again for several hours. Dr. White, V. S., says, "This is the only efficacious fumigation, it having been found that when glanderous or infectious matter is exposed to it a short time, it is rendered perfectly harmless."
