Chloride Of Lime

This being cheap is exceedingly useful for disinfecting ashbins, ashpits, and middens. Only the best quality should be bought, and it should be kept in stoppered bottles or jars, as if stored in paper it becomes useless having lost its strength.

Chloride Of Zinc

This will be found useful for mugs in which infected expectoration is received.

Nitrous Acid Fumes

Dilute a little nitric acid, pouring it into a saucer, then place a small piece of copper in it.


Pour some strong hydrochloric acid into a glass, add to it from time to time a few grains of chlorate of potash.

These two last-mentioned disinfectants are used to disinfect the air in a sickroom and should be placed at a considerable height.

In addition to chemical disinfectants, we must not omit to mention disinfection (1) by boiling; (2) by extreme cold - this, however, is not reliable or practicable; (3) by intense heat.

Public Disinfection

All clothing, books, and bedding, etc., should be sent to the public disinfecting station, there to be subjected to intense heat.

THE WASHINGTON LYONS' DISINFECTOR is one of the best. It consists of a jacketted chamber with a door at both ends. Steam is admitted to the jacket at a higher pressure, and consequently at a higher temperature than that admitted to the inner chamber, thus preventing condensation on the inner walls of the apparatus. In producing a vacuum the air is removed from the chamber and from the interstices of the clothing by means of a vacuum-producing apparatus or air pump, the result being the moment either hot air or steam is admitted to the chamber the goods are at once penetrated and the disinfecting action of the great heat is rendered absolutely certain. In the inner chamber the heat is 2600 Fahr. or 20 lbs. pressure. In the jacket the heat is 2680 Fahr. or 25 lbs. pressure. This process takes thirty-five minutes to thoroughly disinfect all articles subjected to it. Leather boots, felt hats, etc., would be rendered shrivelled and useless, they are therefore treated with formalin.

Book and papers may be suspended on lines across a room when the premises are being disinfected with formaldehyd, or may be placed on end with open pages in an air-tight receptacle and then subjected to the action of formaldehyd for twenty-four hours.

In conclusion, one can only say that owing to the enormous number of disinfectant, antiseptic, and deodorant preparations on the market it is impossible to mention more than a few of the most important, but any reliable chemist will always willingly recommend any appropriate compound, giving full directions for its use.
