...Reimann and his assistant, Bernard J. Miller, obtained an ovum from a Negro woman in the hospital, placed it in a drop of clear white serum strained from human blood, suspended the drop from a glass slide and placed it under a microscope...
...added he startlingly, "of either one of the babies." Superfecundation is a physiological possibility. Ordinarily only one ovum is expelled from one or the other ovary during each monthly cycle. So, ordinarily only one ovum can be fertilized. Ovaries may or may not alternate in ovulation. Occasionally two ova are expelled at the same time or very close together and, if both are fertilized, twins result. According to this possibility, four years ago a South Dakotan claimed that he was father of only one of his wife's twins, and a judge agreed with him. Said Dr. Bundesen last...
...these usually unhappy creatures happen to develop is beyond biology's present knowledge. Dr. Young guesses: "Fundamentally these disturbances of development must rest on the original chromosome formula" in the fertilized ovum which turns into a hermaphroditic baby. The embryo through the sixth to seventh week shows no differentiation into male or female. Thereafter, in the normal course of gestation, the primitive gonad becomes male or female, and the rest of the genital apparatus follows suit. But, in an astonishingly frequent number of gestations, something occurs to interfere with the development of the accessory male or female apparatus...
Yale's learned Neuro-Anatomist Harold Saxton Burr last year revealed that a complicated electrical device he and associates invented could tell when a woman's ovary had produced a full-grown ovum and thus put her in the essential preliminary state for having a baby (TIME, Nov. 23). Such foreknowledge might guide a woman's conduct in case she did not want to have a baby. Professor Burr immediately denied that his "vacuum tube microvoltmetre for the measurement of bioelectric phenomena" provided any such useful domestic data. Disappointed were many good citizens-not all of whom...
...Burr and his subject delayed the operation until the day when previous microvoltmetre readings predicted an ovum would rupture out of a follicle of an ovary and cause a faint electrical upset. That overture to gestation occurred at 7:05 p.m. July 24 and threw the microvoltmetre out of whack for several seconds. Immediately the woman's potential slowly decreased. Said Dr. Burr last week: "The condition continued until midnight when the experiment was terminated in order that the patient might obtain a night's rest. Next morning a laparotomy was done, the ovaries examined...
