In additionto these elements, definitely recognizable chorionic villi are sometimespresent, either of normal appearance or in a condition of vesiculardegeneration ; the origin from the epithelium of the villi of the threevarieties of cells just described has been traced by a number ofdifferent observers. The tumour-elements show no definite arrangement, but are mingledwith one another in irregular clusters and masses, and are sufficiently 556 GYNECOLOGY. Fro. 291.
