The following are the directions for the Prevention of the spread of catching diseases and for the proper disinfection of rooms issued by Dr. C. Meymott Tidy.

1. Recollect that Scarlet Fever or Scarlatina (both terms signifying the same disease), however mild it may be, is highly infectious. Every body and every thing in the room where the sick person is may carry the disease, and in this manner spread it. Small-Pox, however slight, is also infectious.

2. The infectious principle of the disease is given off by the breath, by all the discharges, and also from the skin until long after apparent recovery.

3. Persons with sore throat, when Scarlet Fever is about, sometimes give Scarlet Fever to other people.

4. When anybody is attacked, the sick person should either be put into a room, apart from others, the room being stripped first of all carpets, curtains, and unnecessary furniture, or, where this cannot be done, should be sent to Hospital.

5. When possible, all persons who have not had the disease should be sent out of the house to lodge elsewhere.

6. To prevent the infection corning off from the skin, the whole body and limbs of the sick person should be kept greased with mutton fat, or with some other fatty or oily material.

7. To prevent it coming off by the breath, the mouth, throat, and nose should be very frequently washed with a disinfecting solution, such as water containing some Condy's fluid, by gargling, swabbing, or syringing.

8. Rags should be used instead of handkerchiefs for removing or wiping away the discharges from the throat or nose, and they should then be burned.

9. Before any discharges from the body are removed from the sick room, they should be disinfected and rendered innocuous by the addition to them of a tablespoonful of Chloride of Zinc or common Carbolic acid.

10. The air of the room should be kept sweet and disinfected, and prevented from mixing with the other air of the house. This may be done by constantly keeping up a small fire, and by hanging over the doorway an old sheet well sprinkled with a solution of Carbolic acid (1 part of Calvert's No. 5 acid to 50 of water).

11. No unnecessary communication should take place between the nurse in the sick room and the other inmates of the house. Nurses or attendants should wear glazed or smooth dresses in pre ference to rough and woollen ones, and should wash their hands before eating.

12. All handkerchiefs, towels, sheets, articles of clothing, etc., should be steeped in boiling water containing Carbolic acid (Calvert's No. 5 acid, 1 part to 50 of water), before they are taken out of the sick room.

13. Sawdust, thoroughly saturated with 1 part of Carbolic acid (Calvert's No. 5) mixed with 50 parts of water, should be arranged on large trays, and placed in the various passages and rooms of the house.

should the sick person die.

1. The body should not be removed into another room to spread infection over the house. It is still infectious.

2. No articles of bedding or clothing should be removed from the room until disinfected, as formerly stated.

3. In washing the body, Carbolic acid (1 part in 50 of water) should be used.

4. The body should be put into the coffin as soon as possible, with a disinfectant. Macdougal's Powder may be used, sprinkled freely underneath and over the corpse, or rags soaked in strong Carbolic acid may be laid beneath it and over it (beneath the clothing). The coffin should be screwed down and the body buried as soon us possible.

should recovery take place.

1. Warm baths with soap should be used repeatedly until all roughness of the skin has disappeared: a little Carbolic acid added renders the washing more effective for disinfection.

2. Until all roughness of the skin has disappeared, the person should not be allowed to mix with the rest of the family, and then only in new clothes or in clothes which have been thoroughly disinfected.
