with in the middle
line of the lip and at the angle of the mouth in young subjects. They
usually develop during frosty weather, and as they are constantly
being torn open by the movements of the mouth, they are difficult to
heal. If local applications fail, it may be necessary to cocainise the
fissure and scrape it with a sharp spoon.

_Chronic Induration of the Lips (Strumous Lip)._--A chronic oedematous
infiltration, probably of the nature of a lymphangitis, sometimes
affects the submucous tissue of the lips of delicate children. It is
most common on the upper lip, and may be associated with a fissure or
with chronic coryza. The lip is everted, and its mucous membrane
unduly prominent. The cervical glands are frequently enlarged.

The _treatment_ consists in removing the cause and in improving the
general condition. In cases of long standing it may be necessary to
remove from the inner aspect of the lip a horizontal strip of tissue
having the shape of a segment of an orange.

The term "_double lip_" is applied to a condition occasionally met
with in young men, in which there is a hypertrophy of the labial
glands in the mucous membrane of the upper lip. It is of slow growth,
and forms an elongated swelling on each side of the frenum, covering
the teeth, and projecting the lip. It is shotty to the feel, and the
only complaint is of disfigurement. The treatment consists in excising
the redundant fold of mucous membrane, including the enlarged mucous
glands.

_Tuberculous disease_ may occur in the form of lupus or of ulcers. The
_ulcers_ generally occur in patients suffering from advanced pulmonary
or laryngeal phthisis. They are usually superficial, may be single or
multiple, and are exceedingly painful.

_Syphilitic Lesions._--The upper lip is the most frequent seat of
extra-genital chancre. The _chancre of the lip_ begins on the mucous
surface as a small crack or blister, which becomes the seat of a
rounded, indurated swelling, about a quarter of an inch in diameter.
The surface is smooth, of a greyish colour, and exudes a small
quantity of sero-purulent fluid. The lip is swollen and everted, and
there is a considerable area of induration around. The submental and
submaxillary lymph glands on one or on both sides soon become
enlarged, and may reach the size of a pigeon's egg. At first they are
firm, but they may subsequently soften and become painful. In some
cases the sore is much less characteristic, resemblin
