another, and the pain caused by even the slightest motion deprives the
sufferer of the use of the disabled part and its muscles. Its chief danger
lies in the possibility of its affecting the vital organs. Chronic
rheumatism--the result of repeated attacks of the acute--leads to great
suffering, and oftentimes to disorganization of the joints and an
interference with the movements of the heart.

6. _Lumbago_ is an inflammation of the lumbar muscles and fascia.
[Footnote: Lumbago is really a form of myalgia, a disease which, has its
seat in the muscles, and may thus affect any part of the body. Doubtless
much of what is commonly called "liver" or "kidney complaint" is only, in
one case, myalgia of the chest or abdominal walls near the liver, or, in
the other, of the back and loins near the kidneys. Chronic liver disease
is comparatively rare in the Northern States, and pain in the side is not
a prominent symptom; while certain diseases of the kidneys, which are as
surely fatal as pulmonary consumption, are not attended by pain in the
back opposite these organs.--WEY.] It may be so moderate as to produce
only a "lame back," or so severe as to disable, as in the case of what is
popularly termed a "crick in the back." Strong swimmers who sometimes
drown without apparent cause are supposed to be seized in this way.

7. _A Ganglion_, or what is vulgarly called a "weak" or "weeping"
sinew, is the swelling of a bursa. [Footnote: A bursa is a small sack
containing a lubricating fluid to prevent friction where tendons play over
hard surfaces. There is one shaped like an hourglass on the wrist, just at
the edge of the palm. By pressing back the liquid it contains, this bursa
may be clearly seen.] It sometimes becomes so distended by fluid as to be
mistaken for bone. If on binding something hard upon it for a few days it
does not disappear, a physician will remove the liquid by means of a
hypodermic syringe, or perhaps cause it to be absorbed by an external
