On account of the resemblance to brain matter, theolder pathologists termed them cucephaloid cancers. After theyhave involved the skin, they protrude in the form of a bleeding. TUMORS—CARCINOMATA. 95 fungating mass, and hence were further called fungus in accordance with general usage, the spheroidal-celledcarcinoraata are divided into hard and soft, it should be under-stood that no hard-and-fast hne can be drawn between them, asthe characters of the one often merge into those of the other, sothat sometimes it may be difficult to decide whether an individualspheroidal-celled carcinoma should be classed as hard or soft. Usual seats.—The testis, liver, bladder, kidney, ovary andbreast. Secondary growths in internal organs consequent uponthe dissemination of scirrhous cancer are often of the soft variety. (yC) Colloid, gelatiniform, or alveolar carcinomata.—Theseterms are applied to either of the above-described varieties, orindeed to any form of carcinoma which has undergone mucoidor colloid degeneration. It is believed that the degenerationgenerally begins in the cells which, as they become enlarged,
