PHILADELPHIA. April -.-tSpecial
Correspondence. Professor Arthur
". Goodspeed, of the University OF
Pennsylvania. has reduced the
period of exposure necessary for the
X-ray photograph to the lowest
limit yet reached. He has obtained
a clear picture of the bones of the
hand with au exposure of only four
and one-half seconds.
Professor Goodspeed has not the
advantage of any new or unusual
apparatus. His success is due to
. the fact that he has made an espec-
/ ial study of the arrangement OF the
usual apparatus, namely, the
4 Croohes tube, the Carbutt plate and
an induction coil capable of an eight
inch spark. SO far AS known, no
Aother experiment has been able to
