The lower eunuchoids exhibit a curiously child-like personality.  Naively confiding, communicating to all comers all their joys and sorrows, they ask diffidently for confirmation of their statements, and they pass quickly from tears to laughter.  About sexual matters they are extremely timid.  A moral innocence pervades their speech and conduct.  Usually they have no true conception of crimes of jealousy or passion.  The occupations they go in for are those without responsibility away from crowds or observation, such as ship cooks, stewards, and so on.  They marry to find a home, without the object of establishing sexual relations.  When they are asked whether they think their wives will be pleased to look at the matter in the same light, and be contented to live with a man upon such conditions, they are puzzled or perplexed, as if they had never thought seriously about the matter before.  Their simplicity has even extended to proposing to their wives to seek gratification from some other man.  Naturally, such an arrangement often proves unsatisfactory, and desertion follows.

Concerning the children sometimes the offspring of these unions, scepticism as to the identity of the father is decidedly permissible.  Still in some cases the best of evidence exists that fertility occurs.  The vitality of the children then is subnormal and the mortality rate high.  The eunuchoid tendency is transmitted.  Variations and transitions of every kind are found among the undersexed eunuchoid personalities, depending upon the quality and degree of the secretions lacking.

When there is an excess of these sex secretions, a turbulent, tempestuous, sexually sensitive temperament, that may go on to satyriasis or nymphomania, is created.  It has been shown that doves can be rendered overfeminine in their behaviour and characteristics by injections of ovarian material.  Oversexed types of personality therefore may exist as well as undersexed.

COMBINATIONS AND PERMUTATIONS

The types of personality sketched—­the thyrocentric, the pituitocentric, the adrenocentric, the thymocentric, the gonadocentric—­are really prototypes, the great kingdoms of personality, to which individuals can be assigned, by hall marks which facilitate their classification.  They may also be described as the pure endocrine types, which include a minority of a population.  But the majority consist of dominant mixtures, hyphenates, groups which are the species and varieties of the greater classes.  Combinations and variations of control among the adrenals and thyroid, pituitary or thymus, and so on, occur, with effects that are sometimes additive, reinforcing a particular trait of the person, and at others conflicting, and neutralizing.  Quantitative variations of the same secretion may occur periodically in the same individual, which explains the multiplicity and complexity, the inconsistency and contradictions of conduct in a man or woman at the different episodes and crises of life, to a certain extent.
