among students everywhere. Newspa-
pers and scientific journals were filled
with reports of the labors and new discov-
cries made. There is not an institution
of learning or laboratory worthy the
name in America where the Roentgen
method of photography has not been put
to practical test. One remarkable dis
covery was made incidental to some ex-
per;ments in New York. Prof. Max Os-
tenberg, Of Columbia College, desiring to
photograph the framework of a mouse,
drowned the creature in bucket of water.
The animal remained under water fifteen
minutes after ii had ceased to struggle.
1t had been effectually dead more than an
hour when the apparatvs was finally ar
ranged. 1t was laid upon the plate and
subjected to the powerful rays from the
Crookes' tubes, and after an hour of ex-
posture revived sufficiently to struggle to
its feet and crawl about the plate. Nat
urally this phenomenon excited much in
terest, as a new quality of the Roentgen
rays was disclosed. The possibilities of
benefit to humanity in case the rays are
found upon further examination to pos
sess the revivifying power are vast.
Edison, the wizard, has plunged enthu-
siastically into the new study, and has
largely invented his own apparatus. The
CroOkes' tubes, he thought, disspated
too much of the new energy and he made
some for himself. They are thinner and
give better results. Prof. A. w. Wright,
of Yale, is one of the most Woodworking
scientists who has entered into the new de-
partment of research, and has strikingly
confirmed all of Roentgen's experiments.
Prof. Wright's experiments were made
i, e. -
was found that strong impressions were
obtained upon Photographic plate, even
when it was inclosed in an opaque wrap
ping of black paper and covered with Il
pine board half an inch thick.
Prof. Henry A. Bunstead, of the Shelf
field School at Yale, has also ardently
pursued the investigation of X rays along
with Prof. Wright. Mr., Bunstead has ex-
perimented on several animals He first
took mouse, and the photograph shows
the skull quite clearly. but the bones are
not at all well brought out. With fish
and a frog Mr.. Bunstead also obtained
good results. The backbone of the fish
is easily distinguishable, as is also the
bladder. In the frog the leg bones are
clearly visible. Mr.. Bunstead obtained
good photographs of coins in a heavy
leather case The coins were mixed in
with lot of visiting cards and the case
was placed beneath pine board an inch
thick. He also obtained good photo
graph of pair of eyeglasses placed be-
meath board, and of the kernels of Eng
lish walnuts. All these experiments were
made in broad daylight, and the exposure
of the negative lasted about an hour in
each instance.
Prof. Rike and DIR. Miller, of Toronto,
together with others, have made careful
experiments. They have photographs
clearly defining the bony structure of the
frog and another showing the ease with
which Y rays penetrate wood. A coin,
a bradawl and chisel were exposed. The
tang Of the awl where it enters the wood
can be traced easily. The wood is in half
shadow. Prof. Eugene Haanel. of the
Syracuse University, had marked success
in photographing the interior of frog.
Prof. Haanel and other scientists of de-
gree predict that Edison's attempt to
