“ I have already pointed out that in girls the secondary sexual characters begin to make their appearance at an earlier age than in boys. In the onset of sexual differentiation, the boy thus plays a more passive part than the girl, inasmuch as he retains longer the childish type. None the less, in the boy also certain secondary sexual characters begin to develop comparatively early. Thus, in the second period of childhood, the boy's shoulders often become wider, his muscles stronger, than those of the girl. ”

“ It would be quite wrong to assume that all these differences arise in each individual in consequence of education. It does, indeed, appear to me to be true that inherited tendencies may be increased or diminished by individual education; and further, that when the inherited tendency is not a very powerful one, it may in this way even be suppressed. Observations on animals which exhibit sexual differentiation very early in life, also support the notion of the inherited character of certain tendencies ”

“ I shall subsequently discuss in detail a psychical difference which is the most important of all those connected with the sexual life, namely, the direction of the sexual impulse, which attracts the man to the woman, and the woman to the man. ”

“ In the previous chapter, I have described the differences between the reproductive organs of men and women, and between those of adults and children, respectively. Man and woman are, however, distinguished one from the other, not only by differences in their reproductive organs, but by other qualities as well, some of these being bodily, others mental. Such distinctive characters are spoken of as secondary sexual characters, in contradistinction to the primary sexual characters, the reproductive organs. ”

“ In the case of whooping-cough, we find that two girls suffer for every one boy. As regards circumscribed facial atrophy, which usually begins during childhood, a preponderance of the disease in the female sex is also noticeable. Hysteria was formerly regarded as a typically feminine disease, and although this view has now been shown to be erroneous, the fact remains that girls and women are far more often affected than boys and men. ”

“ The sexually differentiated qualities in any individual may be regarded as inborn, and yet we may admit that the differentiation was originally the result of education, if we suppose that in earlier generations in either sex certain qualities were developed, and that gradually, by monosexual inheritance, the differences became confirmed, until finally they became inborn. ”

“ Many, indeed, and above all the extreme advocates of women's rights, prefer to maintain that such sexually differentiated inclinations result solely from differences in individual education: if the boy has no enduring taste for dolls and cooking, this is because his mother and others have told him, perhaps with mockery, that such amusements are unsuited to a boy ”

“ Diabetes is principally a disease of adults, but occasionally it is met with in children also; among adults, there is a considerable preponderance of males affected with this disease when diabetes occurs in childhood, the disease also exhibits a preference for the male sex, although at this time the peculiar sex-incidence is less marked than in later life. Congenital defects of the heart are commoner in boys, the proportion obtained from a very large number of cases of this kind being 61.6 boys : 38.4 girls. ”

“ Criminological experiences appear also to confirm the notion of an inherited sexual differentiation, in children as well as in adults. According to various statistics, embracing not only the period of childhood, but including as well the period of youth, we learn that girls constitute one-fifth only of the total number of youthful criminals. A number of different explanations have been offered to account for this disproportion. ”

“ I take this opportunity of referring briefly to the fact that, as Max Marcuse [22] reports, certain diseases of the skin exhibit sexual differentiation of type even during childhood. The disseminated cutaneous gangrene of children is far more frequent in girls than it is in boys; Broker, among twelve cases, found ten girls. Alopecia areata, on the other hand, affects both sexes with equal frequency, but affects them at different ages. Whereas during the first years of life girls are more frequently attacked ”

“ Without further discussing the question, to what extent in earlier generations there has been any cultivation of psychical differences, I believe that we are justified in asserting that at the present time the sexual differentiation manifested in respect of quite a number of psychical qualities is the result of direct inheritance. ”

“ The love of self-adornment is almost peculiar to female children; boys, on the other band, prefer rough outdoor games, in which their muscles are actively employed, robber-games, soldier-games, and the like. And whereas, in early childhood, both sexes are fond of very noisy games, the fondness for these disappears earlier in girls than in boys. ”

“ Thus, Sibson states that the characteristic costal type of respiration begins in girls at the age of ten, for which reason some observers have assumed that the wearing of the corset is the cause of its appearance; others, however, among whom Hutchinson may be mentioned, deny this alleged causal connexion, stating that they have observed costal respiration in young girls who have never worn any constricting garments. Unquestionably, sexual differences in the type of respiration become apparent in the later years of childhood. ”

“ Thus, for instance, attention has been drawn to the fact that a girl's physical weakness renders her incapable of attempting violent assaults upon the person, and this would suffice to explain why it is that girls so rarely commit such crimes. ”

“ Such an assumption is the expression of that general psychological and educational tendency, which ascribes to the activity of the will an overwhelmingly powerful influence upon the development of the organs subserving the intellect, and secondarily also upon that of the other organs of the body. ”

“ So, also, it is by no means improbable that the little girl, whose pelvis and hips have already begun to indicate by their development their adaptation for the supreme functions of the sexually mature woman, should experience obscurely a certain impulsion towards her predestined maternal occupation, and that her inclinations and amusements should in this way be determined. ”

“ There are some diseases to which women are especially liable, others which occur by preference in men. To some extent, indeed, this is explained by the special exposure of one sex or the other to certain noxious influences. ”

“ There is, however, general agreement as to the fact that during the second period of childhood mental differences become apparent between the sexes. Such differences are observed in the matter of occupation, of games, of movements, and numerous other details. Since man is to play the active part in life, boys rejoice especially in rough outdoor games. Girls, on the other hand, prefer such games as correspond to their future occupations. ”

“ This emotional mental atmosphere is entered at an earlier age than is commonly imagined; and when such a girl's own personal interests are in any way affected by the occurrences under examination, we are never secure from gross exaggeration and misstatement. Petty larceny becomes robbery with violence ”

“ Clopatt, on the other hand, collected from the literature of the subject 272 cases of hysteria in young children, 96 being boys, and 176 girls. Typhoid is commoner in males; and Möbius lays stress on the fact, which he regards as especially striking, that the difference in the sex-incidence of this disease is manifest even in childhood. As regards colour-blindness, there is a notable preponderance among males, and since we here have to do with a congenital affection, this preponderance is as marked among children as among adults. ”

“ During these periods there are certain differences in respect of growth between boys and girls. Although in general the growth in height of the boy exceeds that of the girl, there is a certain period during which the average height of girls is greater than that of boys. ”
