“In this country [Britain] we have too long, from a sense of mock modesty, neglected the science relating to sex. In Germany this is not so. There we find workers who have elaborated for themselves a new science, and who have given to the world knowledge which is of the very utmost importance. We now know that there are females with strong male characteristics, and _vice-versa_. Anatomically and mentally we find all shades existing from the pure genus man to the pure genus woman. Thus there has been constituted what is well named by an illustrious exponent of the science ‘The Third Sex’.”--Dr. JAMES BURNET, _The Medical Times and Hospital Gazette_, vol. xxxiv., No. 1497, 10th November, 1906. London. “Every citizen of age to fulfil his duties as a citizen, whether he be a father or husband, teacher or pupil, master or servant, official or subordinate, has the right, and owes it as a duty, to know the facts of sexual inversion, to combat and to prevent debauchery, crime and vice, to learn and to teach others the place of inversion in Society, and its morals, the duties of the invert towards himself, and towards other inverts, towards the normal man, and towards women and children. And the duties of the normal man towards the invert are no less--no less difficult, no less indispensable.”--M. A. RAFFALOVICH, “Uranisme et Unisexualité.” Paris, 1896. “That sex inversion is not a chance phenomenon … appears from the fact that it has been observed at all times and in all places, and among peoples quite separate from each other.”--A. MOLL, “Die Conträre Sexualempfindung,” 2nd Edition, p. 15. Berlin, 1893. “Concerning the wide prevalence of sexual inversion, and of homosexual phenomena generally, there can be no manner of doubt. In Berlin, Moll states that he has himself seen between six hundred and seven hundred homosexual persons, and heard of some two hundred and fifty to three hundred others. I have much evidence as to its frequency both in England and the United States. In England, concerning which I can naturally speak with most assurance, its manifestations are well-marked for those whose eyes have been opened.… Among the professional and most cultured element of the middle class in England there must be a distinct percentage of inverts, which may sometimes be as much as five per cent., though such estimates must always be hazardous. Among women of the same class the percentage seems to be at least double--though here the phenomena are less definite and deepseated.”--HAVELOCK ELLIS, “Psychology of Sex,” vol. _Sexual Inversion_, pp. 29, 30. Philadelphia, 1901.
