would be far from right to say that every person who is excessively
modest or timid is a masturbator; but there is a certain timorousness
which seems to arise from a sense of shame or fear of discovery that
many victims of this vice exhibit, and which may be distinguished from
natural modesty by a little experience. One very common mode of
manifestation of this timidity is the inability to look a superior,
or any person who is esteemed pure, in the eye. If spoken to, instead
of looking directly at the person to whom he addresses an answer, the
masturbator looks to one side, or lets his eyes fall upon the ground,
seemingly conscious that the eye is a wonderful tell-tale of the secrets
of the mind.
