lic stamped lettering on the cover of
the box, which was faintly perceptible.

"But Professor Neusser has already announced that the photographing of
the various organs is possible."

"We shall see what we shall see," he said. We have the start now; the
developments will follow in time."

"You know the apparatus for introducing the electric light into the
stomach?"

"Yes."

"Do you think that this electric light will become a vacuum tube for
photographing, from the stomach, any part of the abdomen or thorax?"

The idea of swallowing a Crookes tube, and sending a high frequency
current down into one's stomach, seemed to him exceedingly funny.
"When I have done it, I will tell you," he said, smiling, resolute in
abiding by results.

"There is much to do, and I am busy, very busy," he said in
conclusion. He extended his hand in farewell, his eyes already
wandering toward his work in the inside room. And his visitor promptly
left him; the words, "I am busy," said in all sincerity, seeming
to describe in a single phrase the essence of his character and the
watchword of a very unusual man.

Returning by way of Berlin, I called upon Herr Spies of the Urania,
whose photographs after the Roentgen method were the first made
public, and have been the best seen thus far. The Urania is a peculiar
institution, and one which it seems might be profitably duplicated in
other countries. It is a scientific theatre. By means of the
lantern and an admirable equipment of scientific appliances, all
new discoveries, as well as ordinary interesting and picturesque
phenomena, when new discoveries are lacking, are described and
illustrated daily to the public, who pay for seats as in an ordinary
theatre, and keep the Urania profitably filled all the year round.
Professor Spies is a young man of great mental alertness and
mechanical resource. It is the photograph of a hand, his wife's hand,
which illustrates, perhaps better than any other illustration in this
article, the clear delineation of the bones which can be obtained by
the Roentgen rays. In speaking of the discovery he said:

"I applied it, as soon as the penetration of flesh was apparent, to
the photograph of a man's hand. Something in it had pained him for
years, and the photograph at once exhibited a small foreign object, as
you can see;" and he exhibited a copy of the photograph in question.
"The speck there is a small piece of glass, which was immediately
extracted, and w
