[17] _Psychology of Sex_; Vol. _Sexual Inversion_. Dr. Hirschfeld in his _Statistischen Vatersuchunge uber den Prozentensetz der Homosexuellen_, considers that out of 100,000 inhabitants, 94,600 on the average are sexually normal, 1,500 exclusively homosexual, and 3,900 bisexual.
[18] The existence of this danger was admitted in a debate in the House of Lords on August 15, 1921, on The Criminal Law Amendment Bill. The Earl of Malmesbury, speaking on a proposal to apply criminal prosecution to homosexual offences among women, declared that "the opportunity for blackmail will be vastly and enormously increased." Other speakers concurred in this view, and it was partly on this ground that the proposal was thrown out.
