mentioned are boric acid and calomel, equal parts by weight, blown into the
nostrils and eyes with a powder blower. Water solutions of boric acid,
potassium permanganate and hydrogen peroxide are recommended. Liquid
preparations are applied with pledgets of cotton, oil cans, or atomizers.

Many recoveries can be obtained with careful treatment. It is usually most
economical to kill the severely affected birds. Many poultrymen dispose of
the entire flock as soon as the disease makes its appearance, and clean and
disinfect the premises before restocking.

CHICKENPOX.--In some sections the disease appears in another form, known as
_chickenpox_ (contagious epithelioma), in which nodules form on the skin
along the base of the comb and other parts of the head, or both forms may
be met with in the same flock. The nodules should be treated with vaseline,
or glycerine ointments containing two per cent of any of the common
antiseptics or disinfectants.

ENTERO-HEPATITIS. "BLACKHEAD."--This is a very fatal disease of young
turkeys. Grown turkeys and other fowls are not so susceptible to the
disease. It is characterized by an inflammation of the liver and
intestines, especially the caeca.

_The specific cause_ is a protozoan microorganism, _Amoeba meleagridis_.
Adult fowls and turkeys may act as carriers of the germ, and the young
turkeys become infected at an early period.

_The symptoms_ are diminished or lost appetite, dulness, drooped wings,
diarrhoea, weakness and death. When the disease becomes well advanced, the
head and comb become dark.
