such morbid growths as tumors and cancers into the photographic field,
to say nothing of vital organs which may be abnormally developed or
degenerate. How much this means to medical and surgical practice it
requires little imagination to conceive. Diagnosis, long a painfully
uncertain science, has received an unexpected and wonderful assistant;
and how greatly the world will benefit thereby, how much pain will
be saved, and how many lives saved, the future can only determine. In
science a new door has been opened where none was known to exist, and
a side-light on phenomena has appeared, of which the results may prove
as penetrating and astonishing as the Röntgen rays themselves. The
most agreeable feature of the discovery is the opportunity it gives
for other hands to help; and the work of these hands will add many
new words to the dictionaries, many new facts to science, and, in
the years long ahead of us, fill many more volumes than there are
paragraphs in this brief and imperfect account.




THE RÖNTGEN RAYS IN AMERICA.

BY CLEVELAND MOFFETT.


At the top of the great Sloane laboratory of Yale University, in an
experimenting room lined with curious apparatus, I found Professor
Arthur W. Wright experimenting with the wonderful Röntgen rays.
Professor Wright, a small, low-voiced man, of modest manner,
has achieved, in his experiments in photographing through solid
substances, some of the most interesting and remarkable results thus
