There are no scales, but cellular outgrowths of the epidermis form hairs, which are peculiar to the warm-blooded, suckling animals known as Mammalia. Each hair is embedded in a pit or follicle of the epi- dermis, at the bottom of which it arises by the growth of the epidermic cells which cover a vascular papilla. The bristles of the crayfish or of hairy caterpillars, and the setae of the earthworm, are not true hairs, but cuticular structures secreted by the epidermis. The skin also contains sweat or sudorific glands and grease or sebaceous glands which.
