article, prepared by J. C. Winslow,

will be of general interest:
Milk for a long period of time has
been known to the conveyor OF q
large amount of disease. This is due
to two facts-1st, that milk is one OF
the best of media known for the
growth and development Of bacteria;
End, milk Is a staple article of food
and is used in some way by every
family. u,.
The diseases commonly carried 10y
milk are tuberculosis, typhoid fever,
scarlet fever and septic sore throat
All of these diseases, except tubercu-
losis. appear in the epidemic form, a
sudden outbreak with a sharp de-
crease of cases as soon as the supply
of infectious product is stopped.
tuberculosis.
Because of the length Of time be-
tW cen infection and recognition OF the
disease, tuberculosis can never be
traced directly to milk as an injecting
agent. However, it has been shown
!conclusively that COWS with tubercu-
losis do infect8Rtaeir milk with germs,
The bacteria gets into the milk in

result of tuberculosis of the udder;
End, indirectly, from the manure. IN

In Stunning up the work done in fo.4
American cities on the examination of
milk for the tubercle bacilli we find
that ISL samples OF milk. were tested
and 46, or 8.3 per cent were found to
contain the Drgalisms:. The rate OF
positive ,fndingsSin england is con.
siderably higher, according to some
authorities as high as Is per cent.
As the tubercle sbacilli of bovine orr.
gin differ in certain respects from
these of hClran origin Investigators
have been able to differentiate the
types of the disease. Out of 426 cases
studied by the New York board of
health, 80 were of the bovine type. OF
these 426 cases, 291 we're of pulmon.
