h remain to constitute all that is expressive
in our gestures, physiognomy, and attitudes. Melodic intervals
possess in a high degree this property of provoking impulses of
movement, which, even when repressed, leave behind internal
sensations and motor images. It would be possible to study these
facts experimentally if we had at our disposition a human being
who, while retaining his sensations and their motor reactions,
was by special circumstances rendered entirely spontaneous like a
sensitive automaton, whose movements were neither intentionally
produced nor intentionally repressed. In this way, melodic
intervals in a hypnotized subject might be very instructive."

A number of experiments of the kind desired by Goblot had already
been made by A. de Rochas in a book, copiously illustrated by
very numerous instantaneous photographs, entitled _Les
Sentiments, la Musique et la Geste_, 1900. Chapter III. De Rochas
experimented on a single subject, Lina, formerly a model, who was
placed in a condition of slight hypnosis, when various simple
fragments of music were performed: recitatives, popular airs, and
more especially national dances, often from remote parts of the
world. The subject's gestures were exceedingly marked and varied
in accordance with the character of the music. It was found that
she often imitated with considerable precision the actual
gestures of dances she could never have seen. The same music
always evoked the same gestures, as was shown by instantaneous
photographs. This subject, stated to be a chaste and well-behaved
girl, exhibited no indications of definite sexual emotion under
the influence of any kind of music. Some account is given in the
same volume of other hypnotic experiments with music which were
also negative as regards specific sexual phenomena.

It must be noted that, as a physiological stimulus, a single musical note
is effective, even apart from rhythm, as is well shown by Fere's
experiments with the dynamometer and the ergograph.[94] It is, however,
the influence of music on muscular work which has been most frequently
investigated, and both on brief efforts with the dynamometer and prolonged
work with the ergograph it has been found to exert a stimulating
influence. Thus, Scripture found that, while his own maximum thumb and
finger grip with the dynamometer is 8 pounds, whe
