A young man complained to me of being afflicted with nocturnal emissions of seed during his convalescence. This symptom is not a new one in malignant fevers. Hippocrates takes notice of it[112]. I met with one instance of it among the sporadic cases of yellow fever which occurred in 1795. It sometimes occurs, according to Lomius, in the commotions of the whole system which take place in epilepsy. [112] Epidemics, book IV. VII. The disease made an impression upon the lymphatic system. Four of my patients had glandular swellings: two of them were in the groin; a third was in the parotid; and the fourth was in the maxillary glands. Two of these swellings suppurated. VIII. The yellowness of the skin, which sometimes attends this fever, was more universal, but more faint than in the year 1793. It was, in many cases, composed of such a mixture of colours, as to resemble polished mahogany. But, in a few cases, the yellowness was of a deep orange colour. The former went off with the fever, but the latter often continued for several weeks after the patients recovered. In some instances a red colour predominated to such a degree in the face, as to produce an appearance of inflammation. In Mrs. Vogles a yellowness appeared in her eyes during the paroxysm of her fever, and went off in its remissions. In James Lefferty the yellowness affected every part of his body, except his hands, which were as pale as in a common fever. Peter Brown tinged his sheets of a yellow colour, by night sweats, many weeks after his recovery. There was an exudation from the soles of the feet of Richard Wells's maid, which tinged a towel of a yellow colour. In my Account of the Yellow Fever of 1793, I ascribed the yellow colour of the skin wholly to a mixture of bile with the blood. I believe that this is the cause of it, in those cases where the colour is deep, and endures for several weeks beyond the crisis of the fever; but where it is transitory, and, above all, where it is local, or appears only for a few hours, during the paroxysm of the fever, it appears probable that it is connected with the mode of aggregation of the blood, and that it is produced wholly by some peculiar action in the blood-vessels. A similar colour takes place from the bite of certain animals, and from contusions of the skin, in neither of which cases has a suspicion been entertained of an absorption or mixture of bile with the blood. A troublesome itching, with an eruption of red blotches on the skin, attended on the first day of the attack of the fever, in Mrs. Gardiner. A roughness of the skin, and a disposition in it to peel off, appeared about the crisis of the fever, in Miss Sally Eyre. That species of eruption, which I have elsewhere compared to moscheto bites, appeared in Mrs. Sellers. John Ray, a day labourer, to whom I was called in the last stage of the fever, had petechiæ on his breast the day before he died.
