154 THE GLANDS REGULATING PERSONALITY

 conversation, occupation or any single activity, may become

 sleeping badly, she has a much harder time of it than her pituitary

These samples of premenstrual internal secretion reaction are 

 the extremes of a vast number and variety of types. There are 

 women in an unstable quasi-premenstrual state for the greater 

 part of their lives. Sometimes an infectious disease or a psychic 

 blow will put a woman into this class. The significance of these 

 cyclic changes has been tremendously increased by the recent 

 formal admission of women to participation in public activities 

 on a plane of equality with men. r 



Evidence exists that in man, too, there is some cyclic 

 rhythmicity of his endocrines, which sets np a fluctuation in his 

 physical and mental efficiency. The curves of these variations 

 have still to be plotted, and will doubtless contribute no little 

 to our knowledge of the control of human nature. One unex- 

 purgated fact stands out: the reproductive mechanism of woman 

 has rendered her whole internal secretion system, and so her 

 nervous system, all her organs, her mind, definitely and sharply 

 more tidal in their currents, more zigzag in their phases, more 

 angular in their ups and downs of function, and so less predictable, 

 reliable and dependable.
