oduction of curdled milk. Failing this, milk will
undergo, not lactic fermentation, but _putrefaction_, and thereby
develop highly dangerous qualities.

When a person takes soured milk its lactic acid acts as a powerful
germ destroyer and in a certain concentration it actually kills the
lactic germs as well. It also keeps down the disease-producing germs
of putrefaction which work in an alkaline medium (opposite to acid) by
depriving them of the sugar of the whey.

Boiled milk, if set on one side, in warm weather, speedily becomes
alkaline and putrid or putrefactive. It is in this condition that,
when babies take it, they are made dreadfully ill with diarrhoea and
inflammation of the stomach and bowels. Hence it is the chief cause of
the appalling mortality among infants in hot weather.

Mrs F.K.J. need have no fear of any harm coming to her as a result of
eating cottage cheese, but she should not take the whey unless she has
decided to undergo a whey cure and take _nothing but whey_; in this
latter case, there being no other foods taken, there will be no germs
to act harmfully upon it. If there is much flatulence and stomach or
bowel trouble sweet milk or whey will simply feed the germs which are
the cause of the digestive trouble, or self-poisoning, and are thus
far better discarded.

DIET FOR OBSTINATE COUGH.

Miss N.S. writes:--For the last three weeks I have been troubled
with a very bad cough It started in the first place with a cold
in the head and then it got on my chest, and do what will I
cannot get rid of it. I have been having honey and lemon juice,
and also each morning have taken olive oil and lemon juice beaten
up together, but without (apparently) any effect. I have bad
coughing fits in the night and the next morning I do not feel up
to much.

I may say that I have not taken meat for about six years, and I
try to follow the kind of diet advocated in _The Healthy Life_.

I am 23 years of age and a typist in an office, which is about 4
miles from my home. I try to get out in the fresh air as much as
possible to counteract any bad effects which may arise from my
work. My people at home are very much opposed to my food reform
sympathies and efforts.

This correspondent should consult a sensible doctor about this cough
and thus be on the safe side. It is unwise to allow a cough to become
chronic without ascertaining the cause of it. Cough
