American dentistry has for many years led the

faculty. They have been Yankees OF the iahHces mos'
ingenious in improving the mechanical ART Oh 'e pro-
fesson and most practical in their application Oh inc
principles OF dental science. Not only have american
dental colleges and surgical schools cstaoeneu ep
taton OF being the best in the world but the suoeS
have gone out to the Of The earth to carry the
fame OF the superiority Of Yankee inventive genius ana
mechanical devices. In every European capral
American dentists are found in the enjoyment OF
lucrative practice and established reputation; and there

This learned and copiously illustrated volume the
first of series of three issued for the use OF prac-
tones and students reveals the secret OF the success
of the progressive school Of American dental surgery

reader of his volumes No other work on modern den
tistry contains much unerrng testimony TO the IN
ventive genius of the American school,
Remarkable as the achievements of modern surgery
have BEEN il is in dentistry that many OF the scieh-
tifc miracles have been wrought. There are haruIy
any Irregularities and mspacements BY when features

prevented which not susceptible Oh re-
moval and correction under skilful treatment the
human face can literally be Transformed rom MIS-
shapen and distorted uglness to harmony and beauty
by tie readjustment of forces. Teeth out OF line
and embedded I'm wrong positions can be set IN mo
ton and brought into the right places and reia
lions. This is LARGELY done through regulating ap
paratus; but it is the authors contention that IL Is
by taking advantage of the effects Of misplaced and
ill-dected force that irregularities can be corrected
and harmony produced. 1t is his aim to prove that
the character Of force governs the question OF PAIN
and that the tissue changes in the sockets requisite
for the movement of teeth not necessarily pathological
as has been supposed. AS the tissue changes
which have produced the struggling and drifting OF
teeth out Of their proper positions and relations OF an
tagonlsm have been carried on within the domain Of
physiological and normal conditions the reformatOy
processes must be conducted in harmony with these
principles. Tho old idea was to apply force as an
arbitrary remedy. The new theory Is that force Is to
be brought to bear to facilitate the readjusment
of physiological conditions; that intermittent Is often
more useful than continuous pressure in promoting re-
soratve processes that the tissues will always toler
ATE proper degree of intermittent force If not too
frequently repeated and that any mechanical ap
paratus which can be controlled at will so as
10 attain tilese ends is allowable when oper
aied with these physiological functions in view.
The principles OF this theory OF practice involve Tcog
milton OF fundamental laws OF growth rest and motion
The teeth are enabled TO work out their own redemp
flon from deformity and irregularlty. Physiological
processes are made factors in the operation; tne
tissues are allowed TO benefit from the intermittent
action of labor and and the apparatus is con-
structed and operated so as to be kept within the
limits OF normal conditions and under the patients
control.
This volume reveals the progress of dentistry and
the wonders which are accomplished by the best and
most advanced American school OF operators IL Will
convince odfashOned and indolent practitioners that
they have something to learn If they aim TO Keep
abreast with the deveopments OF their art The
subject is one Of too technical nature to
DO extensively considered outside the journals ana
magazines of the profession. work containing so
great mass of evidence in relation to the advance OF
IDEAS and to the mechanical ingenuity of the operators
can hardly fail TO the reputation Of American
dentistry. The profession is constantly exposed 10
ignorant and captious criticism as deficient in feeling
and as taking delight In causing pain. One OF the
most noteworthy features of this treatise is the stress
that is laid upon the element of pain in regulating the
iegree and character Of force applied In the eformatoy
operations and processes described This serves to
emphasize fact which every candid mind Is forced
70 admit that one of the chief benefits of the progress
p the modern art of dentistry is the mitigation of pain
1t is the authors theory that malformatons and r
Irregularities in mouth and Jaws have been produced
painessy under the operation of physiological laws
and that restoration of beauty Of feature and har
monious action must be effected to large degree
without physical suffering
