White monkeys and white roosters are also worshiped.

In the Natural History Museum in London there are stuffed examples of albinism and melanism in the lower animals.
Melanism is an anomaly, the exact contrary of the preceding.

Such epidermic anomalies as ichthyosis, scleroderma, and molluscum simplex, sometimes appearing shortly after birth, but generally seen later in life, will be spoken of in the chapter on Anomalous Skin Diseases.
Human horns are anomalous outgrowths from the skin and are far more frequent than ordinarily supposed.

Nearly all the older writers cite examples.
