es of treatment in two animals
for troubles which, to the less experienced observer, appear to be
absolutely identical.

_Termination of inflammation._--Like congestion, inflammation may
terminate by resolution. In this case the exuded lymph undergoes
chemical change, and the products are absorbed and carried off by the
blood vessels and lymphatics, to be thrown out of the body by the
kidneys, liver, the glands of the skin, and the other excretory organs.
The cells, which have wandered into the neighboring tissues from the
blood vessels, gradually disappear or become transformed into fixed
cells. Those which are the result of the tissue cells, wakened into
active life, follow the same course. The vessels themselves contract,
and, having resumed their normal caliber, the part apparently reassumes
its normal condition; but it is always weakened, and a new inflammation
is more liable to reappear in a previously inflamed part than in a sound
one. The alternate termination is necrosis, or mortification. If the
necrosis, or death of a part, is gradual, by small stages, each cell
losing its vitality after the other in more or less rapid succession, it
takes the name of ulceration. If it occurs in a considerable part at
once, it is called gangrene. If this death of the tissues occurs deep in
the organism, and the destroyed elements and proliferated and dead cells
are inclosed in a cavity, the result of the process is called an
abscess. When it occurs on a surface, it is an ulcer, and an abscess by
breaking on the exterior becomes then also an ulcer. Proliferating and
dying cells, and the fluid which exudes from an ulcerating surface and
the debris of broken-down tissue is known as pus, and the process by
which this is formed is known as suppuration. A mass of dead tissue in a
soft part is termed a slough, while the same in bone is called a
sequestrum. Such changes are especially liable to occur when the part
becomes infected with microorganisms that have the property of
destroying tissue and thus causing the production of pus. These are
known as pyogenic microorganisms. There are also bacilli that are
capable of multiplying in tissues and so irritating them as to cause
them to die (necrose) without forming pus.

_Treatment of inflammation._--The study of the causes and pathological
alterations of inflammation has shown the process to be one of
hypernutrition, attended by excessive blood supply, so this study will
indicate the
