MOST important advances have been made in dental and gastro-
intestinal radiography and in the standardization of apparatus and
technic. The latter has made possible tables showing the correct
exposure for radiographs of every portion of both sexes and of every
weight and measurement. The saving in time and the certainty of
good results have been obtained by many hundred hours' work in
studying the methods and results in thousands of radiographs. The
rehabilitation of those suffering from the results of war injuries is
.mother important subject.

Then 1 are described in this book inventions, patented and unpat-
ented, and it is not to be assumed because patents are not specifically
mentioned in connection with the various descriptions that there are
no patents or that the rights are not protected.


\F.\S YOKK CITY, .1 /</'</, 1921.



Now that the work approaches completion the author realizes that
it is impossible for any book on electricity to be up to date. A weeklv
magazine would be more apt to justify this title in the case of a science
which is developing so rapidly and along such important lines. A
systematic attempt to present what has been done and of how to do it
may. however, prove useful. Where a statement is ascribed to some
particular observer, this is done either because the statement has not yet
been verified by universal experience or in order to give; due credit to
the discoverer of an established fact. The radiographs in this book
were made by the author except where otherwise stated, and the tech-
nic employed is one available for the average practitioner who desires
uniformly successful results. Lightning speed is attainable by the dis-
tinguished expert, but sometimes at a ruinous expense for j-ray tubes.
The author's frequent use of the name " .r-ray " is perhaps excusable on
the ground that it is the name Rontgen gave to the form of radiation
which he discovered. The author acknowledges, with thanks, his in-
debtedness to Dr. Smith Mly Jelliffe and Dr. Harry F. Waite for their
assistance; and to his assistants at St. Bartholomew's Clinic and to
other gentlemen to whom due credit is given for radiographs made by
them. The authors consulted are mentioned at the respective parts of
the book, but special mention should be made here of the works of
Houston, ,J.J. Thomson, Curie, Albert-Weil, and Bordier, The author's
greatest obligation is, of course, to the professional friends who have
n-fenvd patients to him.

MKDIOAL electricity, or electro-therapeutics, treats of the applica-
tion of electricity to the diagnosis and treatment of disease.

Electricity is known to us through the effects produced when an
electric charge, electromotive force, or potential is developed, just
as the attraction of gravitation is known to us through the effects pro-
duced when a body is raised from the ground. Hodies in which an
electromotive force or potential or electric charge has been produced
are no longer in a state of repose, but tend to produce a variety of
effects, one of the simplest and most direct of which is losing their
electricity to some other body or to the earth, or. in other words,
becoming discharged. Many other effects are produced by the electro-
motive force in seeking a state of equilibrium heat, light, the .''-ray,
mechanic motion, chemic changes, physiologic effects. Practically,
every one of the effects produced by electric discharges is used in
electro therapeutics; and some recapitulation of our knowledge of
electric science is necessary to the proper presentation of the special
methods of producing and applying electricity in medicine.


Electricity is sometimes regarded as a substance consisting of ex-
ceedingly minute negatively charged particles, called electrons, which
are a very great deal smaller than atoms in which they normally are
in a state of equilibrium, with a positive charge which is inseparable from
the atom. And when by the application of various chemical and
physical forces the state of equilibrium of the electrons is disturbed
there are various manifestations of [lower, such a> attraction, repulsion,
heal, light, electromagnetic induction, and chemical dissociation or
elect rolysis.

The electron- are the same regardless of the nature of tin 1 atom-
in which they are found. The underlying fact in the case of a cur-
rent of electricity i> a flow of electron - from the negative pole of the
battery or oilier generator through the external circuit to the positive
pole. If thi< tact had been known ui the I >eginning this would have
been called the direction of the cuiretit instead of the reverse. h H
an untoriunale misnomer, but doe- not make much practical
exc< |)t in considering the pa age of electricity through a vactmii


like ill- 1 ("onlid^e .r-r:iy tube. There the electrons travel from the
negative terminal, and by their impact upon a target u'ive rise to vibra-
tion railed the .r-ruy. and also heat up the target, frequently to in-
camle-cence. And it seems ridiculous to call the contrary- "the direc-
tion < if tin- curn-nt ."

Th>- various familiar means of "generating electricity" are means
of freeing the electron- and applying force to them, which they, in turn,
exert in 1 heir peculiar manner.

Accepting the time honored classification of positive and negative,
the electron- are negative particles of electricity: a neirat ively charged
body contain- an excess of fi-ee electrons and a positively charged
body contains le-s than its normal quota.

"There are t\vo kind- of electricity, positive and negative. Each
ordinary atom contains a number of electrons which are always negative,
and enough ]>o-it ive electricity to exactly balance the negative electricity
of the electron-. At present it appears that the positive electricity
never leaves the atom, while the electrons allow themselves to be taken
away or added to with relative case 1 ." !

An electron i- about rrriMVi the volume of an atom, but it is so

much denser than an atom that its weight is ._,, ,',,,, that of a hydrogen
atom. I' i- sup]>osed to be -pheric in shape.

A charge of electricity is either a surplus of elect n ms. which is a nega-
tive charge, or a ileticit of electrons, which results in a positive charge.

A current <>i electricity is a movement, transfer, or passage of elec-
tron- from one place to another, either free or in negatively or positively
chartrei 1 at< 'in- < >r i< ins.

Electricity manifests itself in three principal forms, covered by the
name- of .-!. '''<, and fnr/nlic electricity. Static electricity is
;. at re-t , : n tending to a sudden discharge and resumption
of eiertric equilibrium. Voltaic electricity is electricity flowinir or
_ Ho\\ in a current. Earadic electrii'ity is a deri\"ed form of
ci;rreni electricity ;n \\hich there are rapid alternations of direction
a- applied in medicine, almo-t always relatively hiii'h ten-ion.
There are -everal tiioi lificat ions of the-e which may be produced by
-ui?:ii in-es, and ainoiiu- them are I.eyden jar di-charnc- and

-fi'eijuency current. Then, again, the secondary

physician to Queen Kh/.abeth, in 1 (>()(). His investigations showed
that many substances possessed this properly, and tho-e in which it
could readily be produced he termed "electrics," from the ('.reek
electron, amber. Among "electrics" art; amber, sealing-wax, glass,
the diamond, hard rubber, sulphur, resin. Any of these, when rubbed
with silk or fur, become- electrified, and exhibits at once; t IK; pro pert ie>
of attracting light bodies which are not charged with electricity, or
which are charged with electricity of the opposite sign, + or (posi-
tive or negative), as the case; may be; of repelling bodies charged with
electricity of the same sign; of inducing an ele:ctric e-harge; in neighbor-
ing bodies by a pn>cess which may be like-tied to an attraction of the;
opposite electricity in the other body, and a repulsion of the; electricity
of the same sign; and of giving sparks or discharging the whole; or a
part of its electric charge to other bodies brought near enough to it.
These 1 sparks are accompanied by sound and a smell of o/one, and
sensation and perhaps reflex muscular contraction if applied to the
human body. A fine examples of the- production of electricity by
friction is obtained when one walks over a woolen carpet, shuffling
his feet, and producing a spark sufficient to light the gas or to give
quite a smart sensation if applied to a person.

" Anelectl'ics " is the name give-n by ( iilbert to t he; metals and < it her
substances in which he- was unable; to excite an electric charge by
friction. We know now t hat the reason was t hat these bodies are- good
conductors of electricity, and that the charge was carried away as
soon as it was produced. A me-tal or any other good conductor may
be charged with electricity by friction, provided it is insulated.

But all substances are 1 not equally charged, and they are' not all
charged with electricity of the same sign or polarity. Those which
would be covered by Gilbert's name', "electrics."' dove-lop the greatest
amount of electricity when rubbe-d. and among them the modern
hard rubber is perhaps the most active.

From the start, it. was ne>ted that glass rubbed with silk, and resin
rubbed with cat's fur, became- differently charged and attracted each
other, while two electrified pieces of gla - repelled each other, as did
two electrified pieces of resin. To these two different form- ot elec-
tricity the 1 te-rms vitreous and rcxinoitx were! applied. l.ate-r. when
it was found that they we're- complementary, and that two equal
e-harge-s neutralized each other, the- vitreous ele-ctricity was called
positive, and given the sign plus, while the- resinous electricity was
called negative, and given the sign minus There i< no special reason
why either one should be called positive. The mimes might jusl as
well have- been reversed. \\hen two dissimilar bodies are rubbed
together, one- becomes charged with positive and the oilier with nega-
tive- elect rich v On the two-fluid theory, friction separated the posi-
tive and negative fluids, and an excess of one fluid remained in one
body, while an excess of the 1 other was formed in the other body. { hi

The attraction of an elect rifled body for other bodies is illustrated
by tin- motion of a pith-ball suspended near an electrified body, such
as ' lu> prime conductor of a static machine. The pit h -ball immediately
swings over in contact with the prime conductor, and as soon as it
touches it i> auiain repelled. According to our diagram (Fig. I), the
positive electricity in the prime conductor attracts the negative elec-
tricity in the pith-ball and repel- its positive electricity. \Yhen The
piti.-ba'.l come- in contact with the prime conductor, it- negative
charge enter- into the prime conductor and neutralizes a portion of
1 he positive charge therein. The pith-ball, being then entirely charged
