THE GLANDS REGULATING PERSONALITY 



head and a fatter face, which point to a predominance of the 

 post-pituitary over the ante-pituitary. Correspondingly, he was 

 more speculative and poetic intellectually than his grandson, and 

 more irascible and imperious in his moods. 



After 1872, when Charles Darwin was sixty-three years old, a 

 marked change for the better occurred in his health. For the 

 last ten years of his life the condition of his health was a cause 

 of satisfaction and hope to his family. "He was able to work 

 more steadily with less fatigue and distress afterwards." T. ; 

 probably to be explained as following the gonadopause in him — 

 the cessation of activity of the interstitial cells. After this event, 

 the adrenals in the male nearly always function more efficiently, 

 and well being is improved even though the blood pressure often 

 rises coincidently. In the relative vigor of that decade we have 

 another bit of evidence that the adrenals had much to say over 

 Darwin's life.

He had a fever when he was in Spain 



And, when the fit was on him, I did mark 



How he did shake: 'tis true, this god did shake 



His coward lips did from their color fly; 



And that same eye whose bend doth awe the world, 



Did lose his lustre: I did hear him groan.

Epilepsy, the "falling sickness" or "fits," is generally associ- 

 ated with a deterioration or degeneration of mentality, and an 

 inferior personality is frequently an ingredient. Pro 



sing data accumulate to incriminate more and more a dis- 

 turbance of the endocrine balance, on the side of multiple de- 

 vies, as the basic mechanism at the bottom of a good many 

 of them. Concurrent studies reveal that abnormality

iymus exist behind tl. ligation of the content

point of view will doubtless bring to li ting in for-
