This man was in such pain with rheumatism that he began to fear he was going to lose the use of his arm. But Kruschen Salts removed the pain, and now he can use his arm as well as ever. His gratitude led him to write the following letter:—

“I have been a great sufferer from rheumatism and lumbago and there have been times when I have not been able to move. About three years ago I had terrible pain in my right arm. I thought I was going to lose the use of it, I could not carry even the smallest parcel. I decided to try Kruschen Salts, and have received great relief. The pain was simply terrible, but I am pleased to say it has all disappeared since I have taken Kruschen. I shall never be without this wonderful remedy.” —N.E.

Unless the kidneys—or body filters—function properly, certain acid wastes, instead of being expelled, are allowed to pollute the bloodstream and produce troublesome symptoms: rheumatism for one: excessive fatigue for another.

What is needed is a special kidney aperient. Ordinary aperients cannot do the work. In the light of presentday knowledge, Kruschen Salts is one of the finest diuretics or kidney aperients available for assisting the kidneys to excrete acid impurities.

The remarkable effectiveness of Kruschen has created for it a world wide sale. It is taken by the people of 119 different countries. In none of those countries is there anything else quite like it—nothing else that gives the same results.

Kruschen Salts is obtainable at all Chemists and Stores at 2/6 per bottle.

Invasion Period. —From the first symptom to the height of the disease is known as the Invasion Period.

Defervescence Period. —From the previous period until the temperature returns to normal, and the germ or virus is no longer active is known as the Defervescence Period.

Convalescence Period. —From the former stage to the time when the patient returns to normal health and strength is known as the Convale scence Period.

Now we will give you a few details concerning some of the more prevalent infectious diseases, taking them in alphabetical order, not in order of importance:—

Chicken Pox. —Incubation Period: 12–21 days. Infection: Contact with patient or with articles soiled by discharges from vesicles. Patient is infective until all scabs have fallen off.

Diphtheria (Notifiable): Incubation Period: Usually 2–5 days. Infection: Contact with discharges, or through contaminated food, such as milk. Infective until bacteriological examination is negative.

Measles. —Incubation Period: 10–18 days. Infection: Contact with patient, or through articles soiled by secretions from nose or mouth. Infective while membranes of nose and mouth are involved.

Mumps. —Incubation Period: 4–25 days. Usually 14 days. Infection: Same as Measles. Period of infectivity is uncertain—allow one clear week after complete subsidence of swelling.

Scarlet Fever (Notifiable). —Incubation: 2–8 days. Usually 3–4 days. Infection: Contact with patient or articles soiled by discharges, or through contaminated food such as milk. Infective for at least 4 weeks from onset.

Typhoid Fever. (Notifiable). —Incubation Period: 5–21 days. Usually 10–14 days. Infection: Similar to Scarlet Fever. Infective until bacteriological test negative.

Whooping Cough. —Incubation Period: 7–14 days. Infection: Same as Measles. Very contagious in early stage before whoop. Infective for two weeks after whoop has disappeared.

Finally, we would impress upon you that even the mildest of these diseases, if not properly cared for, may lead to very serious consequences, hence the necessity for seeking skilled attention in the early stages. Study the method of infection, and do all in your power to prevent spread of disease.
