S. B., aged 16 years, was admitted into the Clapton Asylum, May 7th, 1875, with the following history. She was born a healthy girl, having no mental defect. She enjoyed good health up to nine years of age, when she became the subject of chorea, supposed to have been caused by exposure to the sun. She was sent to Margate, in the hope that the change might prove beneficial to her, but the chorea continued. Four years ago, while bathing, epileptic fits came on, and soon afterwards the chorea ceased. Her intellect is said to have become weak after the fits were noticed. She has never since been free from them. She was sent to Caterham and afterwards to Hampstead Asylum, whence she was transferred to Clapton.

I feel that some kind of apology is due for my venturing to bring before a society which concerns itself mainly with practical questions what I fear will be regarded as a decidedly unpractical paper. Still, it may not be without advantage once in a way to step aside from the more arduous path of observational or experimental investigation in the region of psychiatry with its exacting conditions, and view things from a more general standpoint. And, while confessedly it may lead to no practical outcome, if by challenging some acknowledged views, and raising a breeze of controversy, however gentle, which may ruffle the quiescent surface of the pool of accepted opinion, it should at least suggest some grounds for a reconsideration of certain important questions connected with psychology and psychiatry, the object of the writer will be achieved.

If I fix a square peg into an oblong hole, the fact that they do not fit is instantly perceptible; but it is manifest that the. several percepts of the peg and of the hole must precede the perception of the relation of non-adjustment subsisting between them. Furthermore, if I want to determine how much the peg lacks in size, I must measure separately both the peg and the hole before I can calculate the amount of the hiatus between them. What is true of this simple case of adjustment is true of the complex case of the adjustment of the organism to its environment. However rapid and apparently immediate may be the cognition that a patient is insane—is unadjusted to his environment—yet that cognition must be preceded by a previous knowledge both of the organism itself and of the environment with which his adjustment has failed. The truth of this statement, which is involved in the definition of Insanity, may not be at once apparent, but a little consideration will render it clear. It is manifest that before pronouncing a man insane, we must first know something about him, but that we must also take into account his environment is, perhaps, not so self-evident.

It is to Jung, of Zurich, that we are indebted for the attempted division of attitudes of mind into the introverted and the extroverted types. In his Analytical Psychology he gives us a chapter on types, and in 1924 appeared his large work on Psychological Types. According to Jung, the introverted type of individual is characterized by the fact that his libido is turned towards his own personality to a certain extent—he finds within himself the uncon ditioned value. The extroverted type has his libido to a certain extent externally—he finds the unconditioned value outside himself.
