C. Webster, patches, it takes on a very deep stain—the early stages of the de-generation which has been particularly described by Langhans. Afew small knot-like projections of the epithelium may be seen at in-tervals, but these are far more numerous on the villi. The villus-stems are mostly oblique to the surface, though some are at rightangles to it. The chorionic mesoblast is more fibrillated than in earlier speci-mens, and in parts has a dense appearance. It contains more nu-merous spindle-shaped cells, which, for the most part, lie parallel tothe surface. In different places these cells are arranged under theLanghans layer of the epiblast as a kind of basement membrane, thedistinction between the two thus being clearly evident. In the vil-lous stems the mesoblast is most condensed at the periphery and atthe outer ends. In the small villi it is quite loose, of the delicatemucoid type. In the very youngest villi the mesoblast is very finelygranular, faintly staining a
