DISINFECTANTS.
In addition to what may be found, in the body of this work, upon disinfection in connection with the diseases of animals, the following will be found valuable : The value of chloride of lime and sulphuric acid, which form the most effectual disinfecting material, is here expressed by 100, while the remaining numbers show the value of the other materials as compared with this standard: Chloride of Lime with Sulphuric Acid 100-0 Chloride of LiMe with Sulphate of iron 99-0 Carbolic Acid—disinfecting Powder ...... 85-6 Slaked Lime 84-6 Alum 80-4 Sulphate of Iron 76-7 Chloralum 74-0 Sulphate Magnesia: .. . . ... .. 57-1 Permanganate of Potash with Sulphuric Acid 51-9 Dry Earth. Makes an excellent disinfectant of privy vaults, cesspools and sinks.
To Disinfect Clothing. Subject it to dry heat, as great as it will bear without injury to the tex time_ Condfe's Disinfectant. Crude permanganate of potash half ounce; water half pint. Pat a few teaspoonfuls in the room to be disinfected and renew as often as the solution loses its color.
For purifying foul water a teaspoonful to the barrel is sufficient to sweeten, and if added until a faint tinge of color shows in the water, all injurious organic matter will be destroyed. If the water is for drinking put in a little coffee or tea, a teaspoonful, and the tinge will disappear leaving the water pure and wholesome.
For Privy Vaults or Cess Pools—having a rot ten egg smell, sulphuretted hydrogen, use cop peras in coarse powder. One or two pounds to an ordinary vault will be ample, as a general rule, to remove all unpleasant odor. Where the odor of carbolic acid or chloride of lime is not objectionable, they will prove valuable disinfec tants, especially for drains, etc.
To Ascertain Whether the Air of a Sick Boom is Pure or Not. Dampen a piece of white linen or muslin in a solution of nitrate of lead. If impure the cloth will darken, otherwise remain white.
