st pulmonary symptom noticed, again being
delayed until late; and there are cases in which it does not happen at
all. It seldom occurs in any other disease.

_Night-sweats_ may occur at any stage, though they are rarely
experienced until the disease is pretty well established, and are very
exhausting.

_Hectic Fever_ generally occurs soon after the pulmonary symptoms are
developed, and increases in intensity with the progress of the disease.
There are usually two paroxysms in twenty-four hours, one of which
occurs towards evening and is followed by night-sweats.

_Dyspnoea_ (difficult breathing) is at first slight, except after
exertion, amounting to only a sense of oppression; but it becomes more
and more severe as the disease advances, until the very last, when it is
agonizing in the extreme.

_Aphthae_, sometimes extending to the pharynx and larynx, generally
occurs towards the last. The mouth and throat become so very sore and
tender that nourishment and medicine are taken with difficulty.

_Emaciation and Debility_ are characteristic of the disease. They
fluctuate as the disease advances or is retarded, increasing to the very
last.

_Auscultation and Percussion_ constitute valuable means of diagnosis
from the time tubercular matter begins to be deposited to the very last,
and, when correctly practiced, reveal the extent and progress of the
disease. As a knowledge of the sounds elicited can only be acquired by
practical experience with proper instruments, they will not be described
here. The only diseases with which consumption is likely to be
confounded are general debility in the early stage, bronchitis, chronic
pleurisy, chronic pneumonia, and abscess in the lungs, after the advent
of pulmonary symptoms.

CURABILITY. Notwithstanding the prevailing opinion that consumption is
incurable, there exists ample, incontrovertible evidence to the
contrary. Its curability is established beyond the shadow of a doubt.
Individuals have recovered in whom there was extensive destruction of
pulmonary tissue, and, indeed, entire destruction of one lung. Numerous
instances are on record in which persons have suffered from all the
symptoms of confirmed consumption, and have regained their health and
subsequently died of other diseases. The case of the late Dr. Joseph
Parish, of Philadelphia, affords a striking example of this kind. In
early life, he manifested all the symptoms of confirmed consumption,
including frequent h
