:icis Galton, pioneer student of the conditionings of hi 

 faculty, left an interesting study of the visualising capacity, so 

 far as it could be attacked by the statistical method. Two of his 

 conclusions are worth repeating for our purposes. One is 

 the power to imagine is poor in philosophers and men of s< •; 

 The other that it is higher in the female sex than in the mate. 

 We have seen that the philosophic, scientific, intellectual mind, 

 the capacity to abstract, and think in terms of abstractions, is 

 definitely dependent upon proper secretion by the ante-pituitary. 

 In woman, the post-pituitary is generally predominant over the 

 ante-pituitary. Though we are in need of a series of studies of 

 the endocrine traits and composition of men endowed with high 

 imaginative qualities, and so are at a loss, we have indications 

 of an endocrine control of the state of consciousness we speak of 

 as the imaginative. 



Most of the evidence accumulated in the examination 

 treatment of morbid conditions characterized by a restless, inco- 

 ordinate activity of the brain cells points to excess of the post- 

 pituitary secretion as the cause, or as one of the most important 

 causes. The thyroid and the adrenal medulla also exert 

 influence. But the strongest appears to be the post-pituitary. 

 Phobias, fears which obsess the mind, anxiety neuroses, 

 picions, hallucinations, delusions, nervousness, all expressions of 

 what we may sum up technically as the imaginative state of 

 mind, occur and occur frequently, associated with other symp- 

 toms of posterior pituitary overactivity. Persons in v
