Not illustrated. 1914 edition. Excerpt: ...of papilla; 1F, swelling; T.-Dr., anlage of sebaceous gland: II.-Kan.. hair canal cells; H.-K.. tanrentii I section of a neighboring hair germ (X 430). (After Stfthr: Lchrbucb der Histologic. Fig. 300; Entwicktung des menschlichen Wollhaares. Fig. 9.) Figs. 166 to 177 inclusive show evidence of activity directed toward the development of hair-follicles. The downward growth of the cells of the "stratum germinativum" into the subcutaneous tissue is acconiiNinied by their differentiation into hair instead of epidermis. The examinat ion of a fully developed hair-follicle shows that there still remains a row of cells (Figs. 170 to i inclusive) which correspond to the "stratum germinativum" of the epidermis and may lie considered the stratum germinativum of the hair. The epithelium of nails, sebaceous glands (Fig. 178), sweat-glands (Figs. 173 to 177 inclusive), and mammary glands (Figs. 179, 180, 181) possesses its stratum germinativum, from which its differentiated cells are reformed. From this brief statement of embryologic facts and the photographic facts which are presented here one may crudely construct a working diagram of the probable histogenetic position of the cells which form carcinoma. Figs. 18 (A-7943), t 183 (A8743), and 184 (A2794S) were taken from sections of adenofibroma and non-carcinomatous port ions of carcinomatous breasts. The acini vary greatly in size, some are atrophic, some cystic, and some hypertrophic. They are separated by a fairly dense, irregular interacinar stroma. A few lymphocytes are seen in the field. These pictures correspond to many of the pictures which are published in the literature as "abnormal involution," "senile parenchymatous hypertrophy," "Schimmelbusch' more
