lymphatic glands lying near and among
the muscles may be not infrequently diseased.

(2) Whether tubercle bacilli are found in muscle juice independent of any
tuberculous deposits is a question which must be approached experimentally.
There is on record a great variety of opinions on this matter, some
authorities considering all flesh from tuberculous animals unfit for food,
while others hold a contrary view. Experiments have shown that in rare
cases the flesh of tuberculous cattle contains a small number of tubercle
bacilli. In Germany the flesh of animals in which the disease is just
beginning, or in which it is restricted to one or more related organs, is
not rejected. When, however, the disease has affected the muscles or bones,
or lymphatic glands situated on or between them, the flesh is condemned as
unfit and dangerous. Animals are also rejected in which it is evident, from
the general distribution of tubercles throughout the various organs, that
the bacilli have been distributed by the blood and may have been carried
into the muscular system (generalized tuberculosis).

Concerning the infectious nature of milk secreted by tuberculous cows,
authorities have universally agreed that when the udder itself is in the
slightest degree involved the milk possesses infectious properties, and is
therefore dangerous. Tubercle bacilli in large numbers have been found in
the milk and the udder under such circumstances. Unlike other affections of
the udder, tuberculosis of this organ does not at once change the
appearance and the quality of the milk secreted. Bang states that for at
least a month after the disease has appeared the milk is normal in
appearance and may be consumed and sold without arousing the suspicion of
the owner. Considerable danger is, therefore, involved in this disease, and
the necessity for the careful inspection of dairy cows seems more urgent
than ever.

Authorities are, however, not fully agreed as to whether the milk from
tuberculous cows in which the udder is apparently not invaded by the
disease should be considered dangerous or not. Some incline to the belief
that the milk secreted by healthy udders is never infectious, even when the
lungs or other organs are affected; that, in other words, the tubercle
bacilli are rarely, if ever, separated from the lesions which they produce,
and that the udder itself must be diseased before tubercle bacilli can
appear in the milk. Experiments made with the mi
