The most common kind of sore is the _simple ulcer_, at first excavated, in consequence of the process of ulceration continuing; afterwards the ulceration stops, and granulations, somewhat fungous, supply its place, so that the surface is raised above the level of the surrounding parts, and has a smooth, soft appearance; there is no hardness of the edges, and there is no tendency to slough or extend by ulceration. Sometimes it commences in the form of a pustule, which soon gives way, discharging its contents, and leaving an exposed surface, in which the process of ulceration quickly proceeds; but often it arises from simple abrasion of the surface. Different forms of sores may exist on the glans and prepuce at the same time; and it is maintained, that one sore may produce another of a different kind, and the same is asserted with regard to eruptions. The simple ulcer, as well as other sores, is produced by the contact of secretions, generally morbid, but often apparently healthy, with a susceptible surface. Sores, with eruption and sore throat, sometimes appear in one or both individuals immediately after marriage, and probably arise from the acrimony of the female secretions causing tenderness and ulceration of the parts. The application of gonorrhœal matter readily produces the simple ulcer on the glans or prepuce, particularly if an abrasion or rawness existed; and if the matter be allowed to remain on an unbroken surface, a pustule will form, and ulceration follow. From this latter cause numerous sores are produced, separated from each other by sound parts, and not extending into one continuous ulcer; and this condition may have been preceded, on the glans, by a rawness of the surface and a profuse discharge, or by a herpetic eruption on the mucous lining of the prepuce. One man may be affected with gonorrhœa, and another with ulcer, from connection with the same female, the same day or hour; and it is doubtful whether the effect is not similar, in both cases, viz., ulceration; for it is supposed, that in gonorrhœa, the discharge, in some rare cases, proceeds from patchy ulceration of the mucous lining of the urethra, similar to the ulceration usually met with on the glans. In examining women who have communicated infection, very often no sores are found, and but little unhealthy discharge. In short, the simple elevated sore may arise from the application of secretions from an unbroken surface, from inoculation of matter from a similar sore, or spontaneously, from inattention to cleanliness. Sores with elevated surface, more extensive than those of the glans and prepuce, occur on the skin of the penis and scrotum, or in the folds of the thigh; and in women they are often met with in the perineum, or the cleft of the nates. Sores of different kinds arises at various periods after the application of their cause, from a day or two to some weeks, or longer, but the usual time may be said to be from four to eight days.
