Absolute sterility in women is not an uncommon phenomenon, and want of virile power in the male part of the community is also often the subject of complaint; many quaint drugs and methods being adopted to make up for the want of it, and to stimulate the sexual desire. A good many of the remedies resorted to by the Corean noblemen under such circumstances are of Chinese manufacture and importation. Certain parts of the tiger, dried and reduced to powder, are credited with the possession of wonderful strengthening qualities, and fetch large sums. Some parts of the donkey, also, when the animal is killed during the spring and under special circumstances, are equally appreciated. The lower classes of Cho-sen--as is the case in most countries--are more prolific than the upper ones. The parents are both healthier and more robust, and the children in consequence are stronger and more numerous, but even among these classes large families are seldom or never found. Taken as a whole, the population of Corea is, I believe, a slowly decreasing quantity. The Corean is in some respects very sensible, if compared with his neighbours. Deformities, artificially produced, are never found in Corea. In civilised Japan, on the other hand, as we all know, the women blacken their teeth and shave their eyebrows, while there are numberless people in the lower classes who are tattooed from head to foot with designs of all kinds. In China, too, people are occasionally deformed for the sake of lucre, as, for instance, to be exhibited at village shows, and the Chinese damsel would not consider herself fascinating enough if her feet were not distorted to such an extent as to be shapeless, and almost useless. The head-bands worn by the men in Corea are probably the only causes which tend to modify the shape of their heads, and that only to a very small degree. These head-bands are worn so very tightly from their earliest youth, that I have often noticed men--when the head-band was removed--show a certain flattening of the upper part of the forehead, due undoubtedly to the continuous pressure of this head-gear. In such cases, however, the cranial deformation--though always noticeable--is but slight, and, of course, unintentionally caused. The skull, as a whole, in the case of those who have worn the head-band is a little more elongated than it is in the case of those few who have not; the elongation being upwards and slightly backwards.
