of blood to the brain, and that it thus probably tends
indirectly to preclude amnesia.

There can be no doubt that relaxation diminishes
the inertia of the motor speech-mechanism, and that
the mechanism is then capable of being actuated by a
stimulus weaker than would otherwise be necessary.
When the body-muscles are generally contracted —
and this condition commonly prevails with the
stammerer — the motor cells of the cortex must be
continuously discharging into the efferent nerves.
It seems that the inertia of the contiguous motor
cells —those actuating the speech-organs — is then
increased, and speech rendered more difficult in
consequence. On the other hand, when the muscles
of the body are generally relaxed, there is apparently
a diminution in the inertia of the cells actuating the
accessory muscles. The result, as already stated, is
that the oral articulative mechanism is capable of
being actuated by a weaker stimulus; i<&. by a
weaker auditory or Mnaesthetic verbal image. Re-
laxation would thus preclude stammering in many
Instances when muscular tension would make it
inevitable.

As already remarked, Dr. Sa&dow's expedient is
merely the development of a feature embodied in
practically every commendable system for the treat-
ment of stammering. Of the efficacy of the expedient
there can be no doubt* It counteracts physical
