A new Improvement Of the micro
scope made at Java University con
slsts in so arranging the illumination
that no light can enter the objective
except that reflected by the object I'M

brings into view objects about half the
size OF those formerly proving the linn
it of minuteness.
The unicorn, so long regarded as a
tabled creature, was a horse-like beast
with n single horn sticking out straight
from it's head and it has been sup
posed that it was suggested by the
rhinoceros. Prof Wilhelm Boelsche
points out that bones of huge, horse
like beast that actually did carry such
single straight horn are now known.
1t is called easmotherium, and it was
contemporary of the mammoth in
the Rhine valley and in Siberia.
Prof. A. w Goodspeed of the Uni
versity of Pennsylvania has recently
made X-ray photographs by means of
secondary radiation from his hand ex-
posed to the action Of a Crookes tube,
which was so screened that its rays
could not directly reach the photo
Graphic plate Other things besides
the hand, such as pieces of wood zinc,
and brass, were found to possess
similar property of being excited to
the emission of invisible rays by the
action OF the tube. On two occasions
Professor Goodspeed has suffered from
! inflammation of the eyes and throat
when sleeping in a room where A-ray
experiments had been conducted, and
he thinks the cause may have been the
secondary radiation from the air or OBJ
jects in the room.
Experiments made some time ago
