point indicated deal the patients spine
a violent thrust with his foot, not I'M
frequently evoking EXPLANATIONS of
great pain from the patient. This op-
GRAFTON while unpleasant to the pa
| tient, was almost invariably success
full in removing the ailment.
1.-THE practice obtained in one form
| or another among all the nations de-
scended from the original Settle stock.
Some Of them had devised mechanical
contrivances for administering the
| foot thrust. What their theory of
! philosophy was, If they had any, I
know not, but 1 have met cid Scotch
people who were often eye witnesses
to the operation in remote sections Of
the Highlands Of Scotland, and I met
| one or two who saw the operation
performed In Highland Scotch settle
ments in Canada. Am I not there
fore justified in protecting the good
name and fame of my forefathers
against Bohemian pretens1ons, even
though they be fortified by the spon-
sorsh1p Of our learned associates from
Iowa.
Utility Of tho Thrust.
'The utility Of the thrust in effectu-
ally adjusting luxations, was demon
strated to me in multitude Of cases
long before it gained any clear con-
ception Of it's scientific basis; and I
had repeatedly asked myself the
question:: why is it that an act of
slow movement, say pushing or PRESS
ing-of sufficient power tc put the
luxated bone or vertebrate in place Is
not attended with permanent or abid-
Ing results? I found after repeated
experiments the moment the power OF
push or pressure was withdrawn the
luxated vertebrae would Immediately
assume the same abnormal position as
before, whereas upon the first appli-
cation Of the thrust, the adjusted
vertebrae seemed to manifest an &C.
quiescence in the movement and re-
main in place.
Here comes in the distinction be-
tween the philosophy of our school
and the contentious of another school
very closely allied to our own on the
subject Of causes; but In the matter
far apart in methods as the east Is
from the west
present indications however, point
to the early adoption by the school
referred to, Of the chiropractic thrust.
and l am quite sure every good chiro-
practor who lives his profession, and
ives the good Of his fellow man pre-
cedence over personal or other consid-
erations, will not begrudge to our
contemporaries the adoption of any of
our methods. Indeed they can come
over to us bodily II they want to, and
we shall receive them with open arms,
attaching but one condition to the
heartiness of the reception. VIZ, rnat
they shall leave all their foolishnesses
behind.
Scientific Basis.
But adverting to the scientific
basis Of the thrust, must take YOU
Tor moment into the domain of phy-
sizes, or that branch Of natural science
which treats of matter and energy.
AS Is well known, the property mani
tested by matter in its persistence in
whatever state of rest or Of motion it
may happen to be is called inertia,
and Its resistance to any attempt to
change that state Is similarly desig-
mated.
Nov that which tends to produce
motion In body at rest, or accelerate
one already In motion is called force,
There are. only two ways by which
force can be applied and motion pro-
duced. These are first. by pushing,
second, by. pulling.
These two methods have many
scientific classifcations that need
not dwell upon at this time. For my
present purpose it is sufficient to say
that a force the duration Of, whose
action is exceedingly brief or momen-
tary, comes under the classification
known as impulsive force. Other
forces may be slow continuous, vari-
able, etc., striking nail with ham,
mer and driving It through board;
shooting bullet through window
and making a clean cut hole in the:
glass without cracking. any other por-z
tton, are examples OF the application.
Of tmIulsive force, The sudden jirk
OF the dentist In extracting tooth Is
also an example. The suddenness
with which the force is applied is the
