In this instance the cancer has arisen from an erosion,and the downgrowths show glandular formation which has led tothis type of epithelioma being regarded erroneously as an adeno-carcinoma. The epithelium of the siu-face and that of the deep gland(marked 2) is definitely squamous in character, and it is from the 524 GYNAECOLOGY nature of the epithelium that a cancer is classified. Such spaces as arefound in squamous-celled cancer of the cervix never secrete ; theircontents, as already stated, consist of the solid and fluid products ofdegeneration. Adeno-carcinoma of the Cervix is rare, and like the squamous-celledgrowth it arises from the cervical endometrium, either from the colum-nar epithelium of the surface or from that deeper down in the gland-.

Nullipara, aged growth had formed a small ulcer on the posterior lip of the external section is taken through the edge of the ulcer and shows that the growthhas penetrated into parts still covered by normal squamous epithelium. A gooddeal of round-celled infiltration is seen both in the superficial and deep parts. tubules, the latter source being the commoner site of origin. Thecancer starts by the formation of tubular projections from the lumina ofthe glands. These crypts, communicating with the lumen of anoriginal tubule, begin to branch and elongate, and may join up withothers which have arisen from another site ; hence a complex adeno-matous formation is produced. Some of the secondary tubules mayproject into the lumina {inverting type), but for the most part theyspread outwards in the fibromuscular stroma, which becomes graduallydiminished by the invasion of these ramifying
