position shown in Fig. 2, by means of the single rubber
attachment, the manipulator acts upon the upper portion of the trunk,
neck, head, and arms; by means of the hand-holder, upon the arms; by
means of the double-rubber, upon the arms, shoulders, and scalp.

Rubbing the Arms.]

When the acting part or head is lowered to its extreme limit, the
machine occupies the least space. In this position, by means of the
foot-holder it communicates oscillation to the legs; by means of the
single-rubber, it acts upon the feet, ankles, and lower leg; by means of
the double-rubber, it acts upon the legs, including the feet, the
patient either sitting or lying.

In all of these applications of motion, energy travels from inanimate to
animate matter; non-vital contributes to vital energy: and the various
processes through which vital power is developed are promoted and
carried forward in a degree till the point which constitutes health is
attained.

The name, _Manipulator_, is very naturally applied to the instrument,
the action of which resembles so much that of the living operator. It
is, however, impossible for the unaided hand to impart the degree of
rapidity necessary to secure the effects easily attained by this
machine; and, practically, restoration is often secured in cases in
which it is quite unattainable by any other remedial agent.

Rubbing the Chest and Abdomen.]

Motion, transmitted by the manipulator, exerts a curative effect in
_all_ chronic affections, and is not limited, as is sometimes supposed,
to paralytic affections and deformities. In these latter affections it
is a great assistance in effecting a cure; while, in chronic affections,
whatever the local symptoms, it supplies the additional energy which is
indispensable for recovery in all diseases of long standing.

_Mode of Operation_.--Fig. 4 represents the manipulator in operation.
The machine is propelled by steam power at the Invalids' Hotel and
Surgical Institute, but may be worked by hand, as here represented. One
arm is inserted between the double-rubbing pads, which are raised to
about the height of the shoulders, the patient being seated at the side
of the machine; the other hand is placed on the lever, and as much
pressure is applied as is perfectly agreeable, care being taken to
diminish the pressure at any p
