poonfuls of carbolic acid in a pint of
water before letting the regular milker of the other cows take her. If any
cow in the herd shows the indurated end of the teat or the inflammation and
nodular tender character of the gland, sequestrate her at once and give her
a separate milker. If another cow is to be put into the stall she occupied,
first clean and scrape it, and wet it with a strong solution of bluestone,
5 ounces in a gallon of water. The milk may be drawn off with a teat tube,
or spring teat dilator (Pl. XXIV, figs. 3 and 4), and the milk ducts
injected frequently with a solution of peroxid of hydrogen or iodoform. I
have had little success in checking the upward progress of the disease
through the teat with carbolic acid or boric-acid solutions. Used on the
outside of the other teats, however, they may serve to prevent them from
becoming infected. In the absence of peroxid of hydrogen the affected teat
may be injected with a solution of 1 grain corrosive sublimate in a pint of
water, and the same may be used on the other teats, provided it is washed
off every time before milking.

As additional precautions, no cow with a retained afterbirth or unhealthy
discharge from the womb should be left with the other cows. Such cows
doubtless infect their own udders and those of the cows next them by
lashing with the soiled tail. If milkers handle retained afterbirth or
vaginal discharge, or unhealthy wounds, or assist in a difficult and
protracted parturition, they should wash the hands and arms thoroughly with
soap and warm water and then rub them with the corrosive-sublimate
solution, or if not, at least with one of carbolic acid. Clothes stained
with such offensive products should be thoroughly washed.

The general treatment of contagious mammitis does not differ from that of
the simple form, except that antiseptics should be given by the mouth as
well as applied locally (hyposulphite of soda, one-half ounce daily).

COWPOX.

This is another form of contagious inflammation of the udder which does not
spread readily from animal to animal except by the hands of the milker. It
is held to occur spontaneously in the cow, but this is altogether
improbable, and so-called spontaneous cases are rather to be looked on as
instances in which the germs have been preserved dry in the buildings or
introduced in some unknown manner. It is not uncommon in the horse,
attacking the heels, the lips, or some other inoculated part of
