any means give up a general knowledge of tumors,still, the development of tum_ors in each separate organ demands especialstudy. One of the greatest services rendered by Virchow is that he rec-ognized and filled this need. In the form which we have described, proliferating cysto-sarcoma canonly occur in the mamma; it always includes glandular elements of themamma. The fissure-cysts are the compressed excretory ducts of thelobules, lengthened, displaced, then again distended with fluid. Theterminal vesicles are pressed together, lose their round form and also become fissure-cysts. Vol. IX—0 GG DISEASES OF THE FEMALE MAMMARY GLANDS, IIow the above-mentioned peculiar forms arise is very easily under-stood if we make a fine section of an apparent solid part of such a tumor,but wliicli contains a number of fissure-cysts, and examine it with themagnifying glass or with very low power. At a, in Fig. 21, the termina-tion of an acinus is clearly seen; nothing of the gland-bulbs is seen; they

In this preparation there is nothing ofthe virginal mammary gland, but of the mamma of a woman who hasborne and nursed several children; the spaces which now appear as narrowcanals, not fused together on account of their epithelial covering, wereformerly round gland-bulbs (acini) filled with milk.

It isperhaps very much as iji enormous enlargement of the cutaneous papillte;with their growth also grows the epithelial surface. Therein appears tome to be the proof that the acini can have no true membrana propria,which, unconnected with the connective-tissue floor, is only loosely at-tached to it; if this be the case, it and the
