As a matter of fact, the above given four groups are not to be looked upon as clear-cut microscopic varieties. It is often more easy to classify a tumor clinically than micro-scopically. Experience has shown us that one must be very guarded about assigning atumor to either the group of scirrhus or encephaloid upon the microscopic examina-tion of a single slide. We have seen numerous cases in which a section from one blockof tissue showed the typical appearance of scirrhus, while, another block taken a shortdistance away showed equally typical encephaloid. Many of the slides unclassified were so treated because their tissues showed neither i Plate VII. / I # Mastitis carcinosa. VIII. para; eight montlis after child-birth. Inoperable.

To know nothing of the tumor itself,and to caU it scirrhus because the section shows small cell nests and much connectivetissue, or to call it encephaloid because it shows the reverse, is to fall into egregious blun-ders, for both of these terms are cUnical rather than pathological, and though the micro-scope may explain why the one tumor was small and hard or the other large and soft,why the one might last for years without effecting great destruction, and why the otheris more likely to be invasive and quickly ulcerate, it cannot tell the general structure ofa large tumor when it only shows that of a small fragment.
