much would be done to lessen the danger that arises from tuberculous
cows.
The simplest and most certain method of destroying tubercle germs
in MILK is to BOIL it, and if, in carrying out this operation, the following
rules are observed, the "cooked" flavour objected to by many individuals
will be found to be comparatively slight, and the formation of surface
scum will be practically nil:—
1. Use a double milk saucepan. If, however, this cannot be
obtained, put the milk into an ordinary covered saucepan and place it
inside a larger vessel containing water.
2. Let the water in the outer pan be cold when placed on the fire.
3. Bring the water up to the boil, and maintain it at this point for
four minutes without removing the lid of the inner milk pan.
4. Cool the milk down quickly by placing the inner pan in one or two
changes of cold water without removing the lid.
5. When cooled down, aerate the milk by stirring well with a spoon.
Experimentation has shown that a temperature of 176° F. (80° C.)
is insufficient in all cases to destroy the germs, and great care should
therefore be exercised by those who prefer to use such "Pasteurisers" or
" Sterilisers " instead of simply boiling the milk to ascertain with certainty
that the particular apparatus used is capable of, and actually does raise
the milk to a temperature exceeding that above mentioned, viz., 176° F.
(80° C.).
No steriliser should be looked upon as thoroughly efficient for
the purpose in which a temperature of at least 185- F. (85' C.) is not
attained.
COMPULSORY NOTIFICATION OF PHTHISIS
(PULMONARY CONSUMPTION).
The question whether compulsory notification of phthisis is necessary
to enable Sanitary Authorities to combat this most fatal disease, is one
which at all events in this country is not settled. The Local Government
