Among the diagnostic features of the skin affections the following may be mentioned: They are frequently, and sometimes to a marked degree, symmetrical; more than one type of eruption papules and pustules, for example are present at the same time; there is little itching; they are at first a dull-red colour, but later present a brown pigmentation which has been likened to the colour of raw ham; they exhibit a predilection for those parts of the forehead and neck which are close to the roots of the hair; they tend to pass off spontaneously; and they disappear rapidly under treatment.
The question therefore is whether the somatic modification is inherited. The fact that Proteus does not rapidly become as deeply coloured when exposed to light as ordinary Amphibia shows that the gametic factors for pigmentation have been modified as well as the somatic tissues.
A patient, then aged 21, suffered three years ago from a scotoma almost central; and was first seen six months after that with a macular choroidal atrophy and abnormal pigmentation. She suffered, we afterwards concluded, from choroidal tuberculosis. A recurrence involving adjoining choroid occurred fourteen months ago.
In the later stages there may occur a form of creeping or spreading ulceration of the skin of the face, groin, or scrotum, healing at one edge and spreading at another like tuberculous lupus, but distinguished from this by its more rapid progress and by the pigmentation of the scar. Condylomata are more characteristic of syphilis than any other type of skin lesion.
If the absence of pigment from the lower side in normal Flat-fishes is due to the absence of light, how is it that the pigmentation persists on the lower side of ambicolorate specimens, which is no more exposed to light than in normal specimens? The answer is that in the mutants the determinants for pigmentation are united with the determinants for the lower side of the fish.
Duyse reports a case of extensive hypertrichosis of the back in a girl aged nine years; her teeth were normal; there was pigmentation of the back and numerous pigmentary nevi on the face. Below each scapula there were tumors of the nature of fibroma molluscum. In addition to hairy nevi on the other parts of the body there was localized ichthyosis. Schulz first observed the patient in 1878.
The most general characteristics of eunuchs would appear to be an unusual tendency to put on fat, a notably greater length of the legs, absence of hair in the sexual and secondary sexual regions, a less degree of pigmentation, as noted both in the castrated negro and the white man, a puerile larynx and puerile voice. In character they are usually described as gentle, conciliatory, and charitable.
Indeed, so striking are these variations that they were formerly the basis upon which humanity was divided into races. We have already briefly touched upon the cause for pigmentation and the indications of differences in color. For many years anthropologists were at a loss to understand exactly why some men were black and others white.
The human nutmeg. Extra! Heiress elopes with coast-guard because of his luscious pigmentation! Afterward found to be Tasmanian strain in his family!" Maury sighed; rising he walked to the window and raised the shade. "Snowing hard." Anthony, still laughing quietly to himself, made no answer. "Another winter." Maury's voice from the window was almost a whisper. "We're growing old, Anthony.
The condition shown by the landing-grid suspicions was a case in point. Blueskins were people who inherited a splotchy skin pigmentation from other people who'd survived a plague. Weald plainly maintained a one-planet quarantine against them. But a quarantine is normally an emergency measure. The Med Service should have taken over, wiped out the need for a quarantine, and then lifted it.
