The patient, æt. 34, a lawyer by profession, married, with neuropathic heredity, and having himself presented all his life symptoms of the degenerate temperament—obsessions, labile emotional tone, tremors, etc.,—was accused of immoral acts with boys under his care. It was proved that for many years he had shown a morbid passion for flogging boys about the age of puberty on the bare nates, frequently offering them bribes to get their consent to the operation. He also stroked and pinched the buttocks, but did not at any time touch the genitals, nor did he himself on these occasions show any signs of sexual excitement.
