Soon after, some four months after the miscarriage, she again became pregnant. Also on this occasion dieting had preceded, such as I have frequently carried out for the development of a male individual. But a miscarriage again supervened. The fœtus was obviously male. * * * * * But what was now wanting was an experiment that could be added to the preceding, and would serve to show that a human female, who, under the influence of our method of dieting, invariably bore sons, would, in the case of paying no attention to diet, bring a female into the world. The evidence was forthcoming, for the woman in question again became pregnant without any consideration being bestowed on her bodily condition, and without anything being done to remove the traces of sugar from the urine. After having seven times borne males she became this time mother of a female, which, born before the due time, soon died. After that she was not again pregnant. Probably some change supervened in consequence of which she became permanently unfruitful. * * * * * This incident shows sufficiently that the ovum in the case of the woman who served for our experiment possessed an inherent tendency to develop into a female, and was also ripe enough to be fertilized. As we had exercised no influence upon it so as to effect any change in the ovum (in the same way as we had previously been able to affect the others by the diet in order to procure the ovum of a male) the result was a female. The female tendency was therefore already present in the ovum, and indeed the mother supplied convincing evidence of the female constitution of the ovum whilst it was yet unfertilized, because sugar existed in her urine. The previous determination of the sex could also in this case present no difficulty. In the earlier cases, when male individuals followed one another, we always aimed, by means of our support given by means of the nourishment of the mother, not only at the ripening of the ovum which was to be fertilized, but also at the development of a male individual. In the last case the ovum was, without any assistance, capable of being fertilized, but it developed into a female.
