CARCINOMATA. 697 If we make a section through a hardened preparation of an aci-nous, soft, mammary cancer, when magnified more strongly, the tissueappears as above. I consider the cells in the large connective-tissuemeshes as of epithelial origin (Fig. 159). This variety of mammary cancer is mostly soft, granular on section,grayish white (medullary). If we scrape the cut surface of such acancerous tumor, we readily evacuate a thick, whitish pulp; if we ex-amine this while fresh, we find nodular cells, very pale, composed oflarge, many-formed cells with large nuclei; many of these cells containseveral nuclei; they may perhaps be segregating. The connective-tissue frame-work in which these elements wereembedded, when empty, looks about as follows, if strongly mag-nified : The second form, which is more frequent (is harder, and on sectionpale red), may be termed the tubular form, as the
