Abstract: I WOULD have written a note on this subject long ago, had I not failed to see similar spots general amongst wild animals allied to the dog. The spots may, however, be more general than I am aware. The spots are by no means always tan; a black dog will sometimes have them white, and a white dog black. I have a white-and-tan fox-terrier, in which the spots are very eye-like and jet black; in a brown bull-pug of mine, the spots are also black. These spots are so eye-like, that when the dogs are asleep they seem at first sight to be wide awake.
