In the specimens of Dasyurus described by O'Donoghue, in which the milk glands developed after ovulation without ensuing pregnancy, normally developed corpora lutea were present in the ovary.
She connected it with the fact that Roomoro had eaten the flesh of the little black Dasyurus, christened the "Native Devil" by the first Tasmanian colonists, from the excessive shortness of its temper. The soul of this devil had been driven from the witch-doctor by the poison of the scorpion, and had made for the nearest human organisation.
O'Donoghue, however, concludes from a study of the Marsupial Dasyurus that the stimulus which upon the milk glands proceeds from the corpora lutea in the ovary. In this animal changes in the pouch occur in pregnancy, which are doubtless also due to hormone stimulation, but which we will not consider here. Journ. Mic.
When pregnancy does not occur the corpus luteum is formed, but begins to diminish within ten or twelve days in the human species and is then gradually absorbed. According to O'Donoghue, in the Marsupial Dasyurus there seems to be no difference either in the development of the milk glands or of the corpora lutea between the pregnant and the non-pregnant animal.
