Overthe body of the embryo there is a greenish-colored nodule4 mm. in diameter, which proved to be the degenerated um-bilical vesicle. The legs are poorly formed and stubby. Sections of the chorion show that the mseoderm of the villiis hyaline, in which remnants of blood-vessels may be seen,with a normal number of round nuclei scattered through syncytium also appears to be normal. Between the villisome mucus may be seen, in which there are leucocytes. Nodecidua is attached to the villi. The cord is thin at its attachment to the chorion, and it isslightly enlarged midway between the chorion and the em- 3i6 MALL. [Vol. XIX. Clot Collapsed ovum•-, with embryo.
