tter is applied, and where it has access to the air.

M. M. In this state of the venereal disease once venesection, with mild
cathartics of senna and manna, with mucilage, as almond emulsion, and gum
arabic, taken for two or three weeks, absolve the cure. Is camphor of use
to relieve the ardor urinae? Do balsams increase or lessen the heat of
urine? Neutral salts certainly increase the smarting in making water, by
increasing the acrimony of the urine.

Can the discharge from the urethra be soon stopped by saturnine injections,
or mercurial ones, or with solution of blue vitriol, at first very dilute,
and gradually made stronger? And at the same time lest the syphilis, or
general disease, should supervene, the patient might take a quarter of a
grain of corrosive sublimate of mercury twice a day, as directed below?

2. _Syphilis._ Venereal disease. The contagion shews itself in ulcers on
the part first inoculated, as chancres; ulcers on the tonsils succeed, with
eruption on the skin, especially about the roots of the hair; afterwards on
other parts of the skin, terminating in dry scabs; and lastly, with pain
and swelling of the bones.

The corona veneris, or crown of Venus, consists of the eruptions at the
roots of the hair appearing most round the forehead; which is occasioned by
this part being more exposed to the air; which we observed, at the
beginning of this genus, either produces or increases the virulence of
contagious matter. But it is difficult to conceive from this history, why
the throat should be first affected; as it cannot be supposed, that the
disease is so often taken by the saliva, like the small-pox, though this
may sometimes occur, perhaps very often. The connection between the
genitals in men and the throat, is treated of in Class IV. 1. 2. 7.
Hydrophobia.

M. M. A quarter of a grain of corrosive sublimate of mercury, taken thrice
a day for five or six weeks, made into a pill with breadcrumbs, or
dissolved in a spoonful of brandy and water, is a very efficacious and
almost certain cure. When it does not succeed, it is owing either to the
drug being bad, or to its having precipitated from the brandy, or from its
being spoiled in the pill by long keeping. Opium contributes much to
expedite the cure both of the simple gonorrhoea, and of venereal ulcers, by
increasing absorption both from the mucous membrane, and from the surface
of ulcers.

3. _Lepra._ Leprosy. Leprosy of the Greeks. The skin is rou
