    DEVELOPMENT OF THE MAMMÆ. The mammæ are formed from the two types of cutaneous gland—viz., tubular and racemose. The first stage of development consists of local hypertrophy of the mucous layer of the epidermis, which is depressed into the subjacent dermis, forming a dépréssion known as the glandular area. The primary cellular mass gives out prolongations which divide it and form it into the mammæ. The teat is formed from the glandular area, and may be done in two ways—Jirst, by the edges of the glandular area being elevated and forming the teat ; secondly, the dépréssion of the glandular area, instead of becoming more marked by the élévation of the edges, disappears, and in this way the glandular area rises up to form a projection, which eventually becomes the teat.—{Roule.)
