5, 1901), by inquiries among one hundred medical women, nurses, and women teachers in Toronto concerning the presence or absence of twenty-one different abnormal menstrual phenomena, found that between 50 and 60 per cent.

admitted that they were liable at this time to disturbed sleep, to headache, to mental depression, to digestive disturbance, or to disturbance of the special senses, while about 25 to 50 per cent.

were liable to neuralgia, to vertigo, to excessive nervous energy, to defective nervous and muscular power, to cutaneous hyperaesthesia, to vasomotor disturbances, to constipation, to diarrhoea, to increased urination, to cutaneous eruption, to increased liability to take cold, or to irritating watery discharges before or after the menstrual discharge.

This inquiry is of much interest, because it clearly brings out the marked prevalence at menstruation of conditions which, though not necessarily of any gravity, yet definitely indicate decreased power of resistance to morbid influences and diminished efficiency for work.
How serious an impediment menstrual troubles are to a woman is indicated by the fact that the women who achieve success and fame seem seldom to be greatly affected by them.

To that we may, in part, attribute the frequency with which leaders of the women's movement have treated menstruation as a thing of no importance in a woman's life.
