of infection from tuberculosis and make the little ones live in the
open air and keep away from school. But earlier in the lives of these
children care must be taken. A child with that pale, thin, sallow,
delicate face and poor body should be fed with the best of food and live
in the open air. I once had a family who lost their only two babies
through this disease. After the first one died I instructed them carefully
how to treat the second child. However, they loved their child foolishly
and not wisely and fed it everything it wanted, and you know the children
take an advantage of their parents. Give plenty of good, wholesome
digestible food. Dress them comfortably and warm and keep them out in the
open air. No cakes, candy, peanuts or any food that is not nourishing and
easy to digest.

[INFECTIOUS DISEASES 211]

TUBERCULOSIS. (CONSUMPTION).--Tuberculosis is an infectious disease caused
by the bacillus, tuberculosis, and characterized by the formation of
nodules or diffuse masses of new tissue. Man, fowls and cows are chiefly
affected.

Indians, negroes and Irish are very susceptible. The disease is less
common at great altitudes. Dark, poorly ventilated rooms, such as
tenements and factories and the crowding of cities favors infection, as do
in-door life and occupations in which dust must be inhaled. Certain
infections such as measles, whooping-cough, chronic heart, kidney and
liver diseases and inflammation of the air tract are predisposing factors.
Inhalation is the chief mode of transmission. Hereditary transmission is
rare.

Forms. The Lungs.--Consumption. This is caused by a germ. Some have the
form called galloping consumption. This person is attacked suddenly,
wastes away and dies, in a very short time. There is rapid loss of
strength and weight, high fever, night sweats, fast breathing, pains in
the chest, cough and profuse expectoration, and rapid loss of strength.

Ordinary Consumption.--Begins slowly and the patient is not aware of the
danger. He may have loss of appetite, dyspepsia, diarrhea and distress
after meals. He looks pale, is weak and loses flesh. Soon he has a hacking
cough, worse in the morning, with a scanty, glairy sputum. His weight
continues to decrease, his heart is weak and beats faster. He has pain in
his chest below the shoulder blades. He may have a slight bleeding from
the lungs. His cough becomes worse, the expectoration gets thicker and
more profuse, with night sweats, high fe
