Doctor Carleton Smith. Of New YorS. Has
Photographed His Own Brain.


New York. Feb. i2-The human brain
has been photographed. DR.. Carleton
Simon, Of ia East 56th street, exhibits
a picture OF his own brain. obtained from
a process In which the cathode rays are
not a factor. He has been nearly three
years in completing his experiments. He
tells the story OF his efforts as follows:
Il first sought to accomplish my pur-
pose by passing a continuous curren; OF
electricity through the brain, illuniinat-
ing It by n sl.ark: ani then | tried an in
terrupted current. but this produced par

results. There were many students of th'
college present while the professoc mad'
his experiments and explained the various
phenomena as fast as they developed, ans
all were most deeply interested in them.
The first photograph taken by the pro
fessor was OF the hand of one Of th'
attendants Of the college. The pictur
was excellent and showed the bones an'

Next, the professor put some nails II

In speaking later OF his experiment

l Pupin said that the whole thing was yer
simple. and that the only difficulty Ia
in getting the correct apparatus and
making the pictures under favorable cor
ditions. Crookes tubes are very exper
slve, and for that matter they are yer
f, scarce also, so scarce, in fact, since sc
entlsts began photographing the invisibl
with them, that dealers in the tubes hay
been forced TO cable to Europe for fu
supply of them.
