Much dependedAzpon the details of tech-
nique. For instance Thompson's tube
was better adapted to deeply seated or
gans in the adult. while Collardeau's
gave remarkable results NJ fineness of
details for the adult extremities and
bodies of infants. The time required had
been 40 reduced that the method was ap-
plicable even to infants and others who
could not remain long immobile. The
first photographs showed only the bony
skeleton, while later ones showed also
muscle bundles, their tendinous insert
ion, and the nails with the bones back of
them.
"Dr. vedel showed an x ray photo
graph which enabled him to dffferentiate
between pseudo -osteo- arthropathy and
true osteo-arthropathy. the case Illus
trating the former condition"
WHAT THE x RAY CAN DO.
1t discovers flaws and weddings in
metals, and the amount Of metals in Diff
ferent ores.
It distinguishes between the true dia-
mond and its paste imitation.
A powerful ray may painfully affect
the eyes continuously viewing It through
a Horoscope. Experimenters consider
ably exposed to 1t have, in several in
stances, reported Inflammation of the
eyelids and upper lips, and of the face
generally, as in sunburn.
1t will prove Of great value in court
records in damage cases for bodily in
jury. Comparison of the x ray internal
view Of the injured part with the normal
uninjured part corresponding to 1t will
have great effect upon the jury.
Handwriting in sealed envelopes can
be photographed by it. In one instance
It Is claimed that this has been done
with an X ray after it has passed
through human skull.
In diagnosing diseases the soft tis-

except the bones, 1t not only determines
whether they are diseased, but locates
the area over which the disease extends.
The rise and fall of the ribs in respi-
ration, the beating of the heart,
the outlines Of organs like the liver, the
vertebrae and the greater bones may
all be seen In the body of a person
placed between the Crookes tube and
the Horoscope, but all with more or
less indistinctness. Only a surgeon
knows the difficulty of finding such an
object as bullet or a needle concealed
in the flesh, and the Importance often
times of its localization. II the bullet
fired into the body of General Garfield
could have been located his life might
have been saved.
In case of war an x ray outfit would
prove of incalculable value in locating
bullets in the body. The English war
Office Is said to have already sent two X
ray outfits with>the military expedition
up the Nile.
The United States navy is contem-
plating equipping each Of its vessels
with x ray outfits.
Bones are partially penetrable to
strong rays. This was shown in the
| test in Dr. Yoakum's office, where DR..
| Bicknell detected the $5 gold piece be-
hind the hand and wrist bones of Judge
| Widney.
Substances being Opaque in the ray
| in the ratio of their density, abnormal
| concretions Of calculi, or bone-like ma
| terials, which OCCUR in the organs OF
| the body can be detected.
The density of the teeth is greater
| than that of the jaw bone and pictures
| ing every fang and root, however deeply
| imbedded it may be in its socket.
| Tooth filings and their extent and
| area are easily located, whether visible
| externally or not.
Children's teeth may be seen before
| cavity Of the tooth can be outlined and
diseases within the teeth detected. Dis
eases Of the bone and gum may also be
seen. A dentists lost drill can easily
be found.
| A stiff joint brought on by fracture
or disease may be caused by growth
| of bone, or Of soft tissue equally OBJ
| more difficult to relieve than the other
| and the methods of treatment are
| widely different. In the x ray one is
opaque, the other transparent, and a
positive diagnosis, therefore easily Sc
cured by It.
By means Of the x ray 1t is possible to
readily detect and diagnosticate frac-
lures and dislocations Of bones, and tC
| determine whether the injury Is only Q
| fracture or a fracture and dislocatior
| together which often occurs.
Irregularities and deformities of the
bones are clearly indicated and, in con
| sequence, such diseases as tuberculosis
and cancer which, destroying the bone
| structure, affect it's density, may be de.
tected. In some instances the marrow
cavity has been exhibited by the x ray
The condition of a bone setting may be
| determined and corrected If found
| wrong, and the progress of its union bs
| inspected without removal of splints
| Arteries and veins of dead bodies may
| be injected with substance OPAQUE tt
the x ray, and their locations more ac
curately followed than by dissection. A
like method would apply equally Wel
to the study of other structures and or.
gans of the body. x ray photography
may replace, in measure, both viv {
section and dissection. For example, 6
living subject could drink a harmless
fluid more or less opaque to the x ray
or an effervescing compound to distenC
the stomach, and its outline then coult
be clearly determined from differen,
points of view.
