Jeyes' Fluid

To many people the fact that this has held the Royal Warrant for three successive reigns may be an evidence of its value; it is also spoken of highly by many eminent medical men.


1. It is non-poisonous, and may be used by inexperienced persons.

2. Even in a pure state it has no corrosive action.

3. It is highly concentrated, and may be diluted with from I to 500 parts water.

4. It is cheap, a shilling bottle producing from 6 to 30 gallons of disinfectant.

5. It mixes in the form of an emulsion, and is therefore adapted for spraying.

6. It kills germs promptly, also spores upon which some disinfectants have not a complete action.

7. It also has a deodorant action.

Sanitas fluid is eminently suited as a disinfectant for popular and medical use, inasmuch as it is wholly harmless, also thoroughly reliable both as (1) a germicide, (2) an antiseptic, and (3) as an oxidant it vitilizes and purifies the air.

It is prepared in various forms - sanitas fluid, sanitas-bactox, sanitas-okol - and is used for the same purposes as the foregoing.

It may be of interest to note that: A 20 per cent solution of sanitas fluid kills the typhoid bacillus in from 2 1/2 to 5 minutes.

A 40 per cent solution kills the diphtheria bacillus in 15 to 20 minutes; the pure sanitas fluid killing it in less than one minute.

Sanitas fluid when used as a spray kills the typhoid bacillus on a papered wall in between 20 and 30 minutes.


Formalin is a chemical compound of great use as a disinfectant. Clothes, slates and pencils may be steeped in a solution of it (1 in 40) and are then guaranteed to be immune from infection ; it is also used in the same proportion for spraying walls.

If a gaseous disinfectant is desired the best probably is formaldehyd, as it is a very active germicide when diffused with steam into the air; for good results, however, a plentiful supply of formalin must be used.

Special lamps are prepared for the use of formalin, called Alformant A, costing 9/-. They are small and portable, easily worked, clean, effective, and do not affect textures or colours. Fifteen or twenty formalin tablets to every 1000 cubic feet of space to be disinfected are placed in the receptacle of the lamp, which is lighted with methylated spirit. An ordinary artisan's bedroom is usually about 1500 cubic feet, and would therefore require twenty-five tablets. Each Alformant A is capable of gasifying up to 140 tablets at a time, and is therefore sufficient for a room of 7000 cubic feet. The room must be kept as airtight as possible for from three to six hours.
