elium like wet tissue-paper. They are best
seen on the inner aspect of the cheeks, the soft palate, uvula, pillars
of the fauces, and tonsils. In addition to mucous patches, there may be
a number of small, _superficial, kidney-shaped ulcers_, especially along
the margins of the tongue and on the tonsils. In the absence of mucous
patches and ulcers, the sore throat may be characterised by a bluish
tinge of the inflamed mucous membrane and a thin film of shed epithelium
on the surface. Sometimes there is an elongated sinuous film which has
been likened to the track of a snail. In the _larynx_ the presence of
congestion, oedema, and mucous patches may be the cause of persistent
hoarseness. The _tongue_ often presents a combination of lesions,
including ulcers, patches where the papillae are absent, fissures, and
raised white papules resembling warts, especially towards the centre of
the dorsum. These lesions are specially apt to occur in those who smoke,
drink undiluted alcohol or spirits, or eat hot condiments to excess, or
who have irregular, sharp-cornered teeth. At a later period, and in
those who are broken down in health from intemperance or other cause,
the sore throat may take the form of rapidly spreading, penetrating
ulcers in the soft palate and pillars of the fauces, which may lead to
extensive destruction of tissue, with subsequent scars and deformity
highly characteristic of previous syphilis.

In the _Bones_, lesions occur which assume the clinical features of an
evanescent periostitis, the patient complaining of nocturnal pains over
the frontal bone, sternum, tibiae, and ulnae, and localised tenderness on
tapping over these bones.

In the _Joints_, a serous synovitis or hydrops may occur, chiefly in the
knee, on one or on both sides.

_The Affections of the Eyes_, although fortunately rare, are of great
importance because of the serious results which may follow if they are
not recognised and treated. _Iritis_ is the commonest of these, and may
occur in one or in both eyes, one after the other, from three to eight
months after infection. The patient complains of impairment of sight and
of frontal or supraorbital pain. The eye waters and is hypersensitive,
the iris is discoloured and reacts sluggishly to light, and there is a
zone of ciliary congestion around the cornea. The appearance of minute
white nodules or flakes of lymph at the margin of the pupil is
especially characteristic of syphilitic iritis. Wh
