ORIENT asks us for “a method of permanently removing fat from her nose.” But as she says “sometimes it disappears altogether, and at other times it becomes very thick,” we can tell her for certain that her nose does not get swollen from a deposit of fat. When fat deposits in the nose, it comes to stay. Let her use an ointment of calamine or ichthiol, and attend to her digestion. MADGE.—Colour blindness is an incurable condition. It is congenital and frequently hereditary. There are various grades of the affection. The three primary colours (physiological) are red, green, and violet, and there is a separate set of nervous cells to appreciate each of these primary colours. In colour blindness one or more of these sets of cells are absent. Thus colour-blind persons are blind to red, to green, or to violet, or to two or all of these. Total colour blindness is uncommon. Very frequently the subjects of colour blindness are quite ignorant of their condition. WORRIED.—Read the answer to “Orient.” Though indigestion is the commonest cause of red noses, there are other causes such as diseases of the nose and feeble circulation. In your case undoubtedly the chief factor at work is the last. You should dress yourself warmly, and always wear a veil when you go out for a walk. Take a nutritious but easily digestible diet with plenty of warm milk. Always wash in warm water. Locally you may use the ichthiol ointment or a little cold cream. OUR GIRLS’ BROTHER.—The question of the intermarrying of cousins is a very important one, and deserves a little consideration. The whole question turns upon hereditary tendency. Let us take an example. Miss Smith is going to marry Mr. Jones. The woman brings to the union the hereditary tendencies and the family peculiarities of the Smith family. Mr. Jones brings those of the Jones family. The future Master Jones will inherit the tendencies of both his parents, and his mind may be represented as partaking of the following, “self-Jones-Smith.” That is to say, he has inherited something from the Jones family and something from the Smith family to add to his own original self, which, of course, is far the most important item. But suppose these persons who are going to marry are cousins: here there is only one family’s tendencies to be inherited, so their offsprings will get a little less to inherit, but the tendencies which they do inherit, being derived from both parents, will be very much more marked. The result of the constant intermarriage of relatives is to strengthen the family tendencies, and to render the minds of the future generations one-sided but not, if the family is a healthy one, incompetent. So there is little or nothing against the intermarriage of cousins once or perhaps twice. And there would be but little against constant intermarriage in a family which was absolutely healthy, which in the human race is practically impossible. Now suppose, in a family, one member
