The beginning of the last menstrual period was on May7, and the abortion took place on June 11, 1897. The entireovum was preserved in strong alcohol. The villi of the chorion appear atrophic, being wanting onone side of the ovum. After the ovum was carefully cut inhalf it was found filled with magma partly reticular and partlygranular. On one side is a snake-like embryo with straight-ened head and atrophic extremities. The embryo, with apiece of chorion to which it is attached, was cut into serialsections.

The brain and spinal cord of the embryo aredilated and dissociated,—probably macerated also. The out-lines of the organs and body cavity are obliterated. Theboundaries of the liver can no longer be determined. Thetissues of the body are generally dissociated and they, withthe umbilical cord and magma, are infiltrated with migratingcells. The heart, large veins and aorta are greatly distendedwith blood. The head is atrophic. No. 110. Ovum, 46 x 30 x 30 mm.; embryo, C. R., 8 mm. Dr. West, Bellaire, Ohio. The last period of the woman began September 22, 1897,and lasted five days. On December 8 there was a slight flowwhich continued until the 13th, when the abortion took in alcohol. The sh
