tudy. The relation of the new rays
to thought rays is being eagerly discussed in what may be called
the non-exact circles and journals; and all that numerous group
of inquirers into the occult, the believers in clairvoyance,
spiritualism, telepathy, and kindred orders of alleged phenomena, are
confident of finding in the new force long-sought facts in proof of
their claims. Professor Neusser in Vienna has photographed gall-stones
in the liver of one patient (the stone showing snow-white in the
negative), and a stone in the bladder of another patient. His results
so far induce him to announce that all the organs of the human body
can, and will, shortly, be photographed. Lannelougue of Paris has
exhibited to the Academy of Science photographs of bones showing
inherited tuberculosis which had not otherwise revealed itself. Berlin
has already formed a society of forty for the immediate prosecution
of researches into both the character of the new force and its
physiological possibilities. In the next few weeks these strange
announcements will be trebled or quadrupled, giving the best evidence
from all quarters of the great future that awaits the Roentgen rays,
and the startling impetus to the universal search for knowledge that
has come at the close of the nineteenth century from the modest little
laboratory in the Pleicher Ring at Wuerzburg.

On instruction by cable from the editor of this magazine, on the
first announcement of the discovery, I set out for Wuerzburg to see the
discoverer and his laboratory. I found a neat and thriving Bavarian
city of forty-five thousand inhabitants, which, for some ten
centuries, has made no salient claim upon the admiration of the world,
except for the elaborateness of its mediaeval castle and the excellence
of its local beer. Its streets were adorned with large numbers of
students, all wearing either scarlet, green, or blue caps, and an
extremely serious expression, suggesting much intensity either in the
contemplation of Roe
