III. The Human Eye — Albinism
Now we have to go into the structure of the eye a little if we want to talk about such a thing. This is connected with the other question you have asked. Namely, that especially in Negroes, but also otherwise, in non-black people, an abnormal, not quite ordinary skin coloration occurs, which is connected with the special coloration of the iris. This is connected in a certain way. Now this skin color is particularly noticeable in naturally black people, because they are just black, and then they have all kinds of white spots, and are then mottled like a tiger. They are very rarely completely pale and completely white; this occurs very rarely among Negroes, extremely rarely. But such so-called albinos also occur in other races that are not completely black. But this albinism also occurs in white people, in the so-called cockroaches – that's what they're called – they have a very pale skin color, almost milk-white skin color. Then they usually have a light reddish iris, and the pupil, which is otherwise black in humans, is then dark red. I once saw a female cockroach like this who even exhibited herself in all kinds of sideshows and let herself be seen. She had milky-white skin, a red iris or rainbow-shaped pupil, dark red pupils instead of black eye stars, and would then say in an extremely weak voice: “I am all white, have red eyes and see very weakly.” That was true, she saw very weakly.
