ery much deranged. Although chronic catarrh is most commonly brought on
in the manner above stated, it sometimes makes its appearance as a
sequel of typhoid fever, scarlet fever, measles, or other eruptive
fevers, or shows itself as a local manifestation of scrofulous or
syphilitic taints in the system.

Injury to the nose may result in a displacement of one or more of the
bony structures, setting up a chronic inflammation with catarrh at that
point. In the early stages of the disease, the patient may be annoyed
with "only a slight dropping into the throat," as many express it, the
amount of the discharges from the air-passages of the head at this stage
of the disease being only slightly in excess of health. In some cases
the discharge is thick, ropy, and tough, requiring frequent and strong
efforts in the way of blowing and spitting, to remove it from the
throat, in which it frequently lodges. In other cases, or in other
stages of the same case, the discharge is thin, watery, acrid,
irritating, and profuse. The nose may be "stopped up" from the swollen
and thickened condition of the lining mucous membrane, so as to
necessitate respiration through the mouth, giving to the voice a
disagreeable nasal twang. From the nature of the obstruction in this
condition, it is useless for the sufferer to endeavor to clear the
passage by blowing the nose; this only tends to render a bad matter
worse, by increasing the irritation and swelling of the already
thickened lining membrane. The swelling of the mucous membrane does not
in all cases become so great as to cause obstruction to respiration
through the affected passages. In some cases, the patient suffers from
head ache a great portion of the time, or experiences a dull, heavy,
disagreeable fullness or pressure in the head, with a confusion of his
ideas, which renders him quite unfit for business, especially such as
requires deep thought and mental labor. Memory may be more or less
affected, and the disposition of those who are otherwise amiable is
often rendered irritable or morose and despondent. The mental faculties
suffer to such an extent in some cases as to result in insanity. The
sense of smell is in many cases impaired, and sometimes entirely lost,
and the senses of taste and hearing are not unfrequently more or less
affected.

OZAENA. The ulcerous or more aggravated stage of the disease, from the
offensive odor that frequently attends it, is denominated _Ozaena_.
