ous organs of the body perform their functions
abnormally. On the other hand, the healthy animal moves freely, has a
bright eye and moist nostril and a clear skin, the respiration is not
hurried and the breath has no unpleasant odor, the circulation is
tranquil, and the appetite good, thirst not excessive, and, if ruminant,
when in repose, chews the cud.

There is, however, one exception to this general rule, and that is in
the case of tuberculosis, since the most scientific observations have
failed to trace any connection between the inception of tuberculosis in
man and the eating of meat from tuberculous animals, or to show any evil
effects to man from eating the flesh of cows affected in the first
stages of tuberculosis. The regulations of the United States Department
of Agriculture on this point are as follows:----

"All carcasses affected with tuberculosis and showing emaciation shall
be condemned. All other carcasses affected with tuberculosis shall be
condemned, except those in which the lesions are slight, calcified, or
encapsulated, and are confined to certain tissues ... and excepting also
those which may ... be rendered into lard or tallow."

The regulations referred to say in substance that when the lesions occur
in a single part of the body, as in the neck, liver, lungs, or in
certain specified combinations, the meat may be used; but that where the
lesions affect more than one or two parts of the body, the carcass must
be rendered at a temperature of not less than 220 degrees Fahrenheit
for four hours into lard or tallow.

This really means that an animal only slightly affected with
tuberculosis, where the lesions are slight and are confined to the
tissues of certain organs only, may be used for food. This has been
decided only after very careful reading of all known facts, and is
particularly important in view of the opposition to the use of milk of
tuberculous cows. The tuberculin test, on which depends the
determination of tuberculosis in cows, is so delicate that a very slight
lesion is sufficient to cause a reaction. The lesions are so slight as
in many cases to be entirely overlooked by the ordinary butcher. The
United States regulations allow such a carcass to be butchered and used
for food after the cow has been condemned by the tuberculin test as a
milk-producing animal. This does not mean, of course, that those parts
of the body affected by the tuberculosis lesions shall be used, but,
since th
