by a special odor. 

If the body odors tend to develop at puberty, to be maintained during 

sexual life, especially in sympathy with conditions of sexual disturbance, 

and to become diminished in old age, being thus a kind of secondary sexual 

character, we should expect them to be less marked in those cases in which 

the primary sexual characters are less marked. It is possible that this is 

actually the case. Hagen, in his _Sexuelle Osphresiologie_, quotes from 

Roubaud's _Traite de l'Impuissance_ the statement that the body odor of 

the castrated differs from that of normal individuals. Burdach had 

previously stated that the odor of the eunuch is less marked than that of 

the normal man.
