CHAP. 53.—THE DIVERSITY OF THE COLOUR OF THE EYES.
The eyes vary in colour in the human race only; in all
other animals they are of one uniform colour peculiar to the
kind, though there are some horses that have eyes of an azure
colour. But in man the varieties and diversities are most
numerous; the eyes being either large, of middling size, remarkably small, or remarkably prominent. These last are
generally supposed to be very weak, while those which are
deep-seated are considered the best, as is the case also with
those which in colour resemble the eyes of the goat.
