Every one must have heard of cases of albinism, prickly skin, hairy bodies, etc., appearing in several members of the same family. If strange and rare deviations of structure are truly inherited, less strange and commoner deviations may be freely admitted to be inheritable.

To them, however, might also be added manifestations of albinism though I have never seen an absolute albino in Corea such as, large patches of white hair among the black. Red hair is rarely seen. The Corean, apart, that is, from these occasional defects, is well proportioned, and of good carriage.
Geoffroy-Saint-Hilaire has noted that albinism can also be a consequence of a pathologic condition having its origin in adverse surroundings, the circumstances of the parents, such as the want of exercise, nourishment, light, etc. Lesser knew a family in which six out of seven were albinos, and in some tropical countries, such as Loango, Lower Guinea, it is said to be endemic.
We have here, I think, an example of the essential difference between mutations and somatic modifications. Absence of the gametic factor or factors for pigmentation results in albinism, and no amount of exposure to light produces pigmentation in albinos, e.g. albino Axolotls which are well known in captivity. Absence of light, on the other hand, prevents the development of pigment.
