260 Seeing through a grindstone
Roll up a piece of stiff paper with
one End just large Enough to fit round
the Eye, and the other End rather
smaller. Hold the tube betweent the
thumb and forefinger (do not grasp
it with the whole hand) put the
large End close against the right Eye
and with the left hand, hold a book
or any conveniant opaque body, against
the side of the tube. Be sure and
Keep both Eyes open, and there will
appear to be a hole through the body
and objects are seen as if through a
hole instead of through the tube.
The right Eye sees through the tube
and the left Eye sees the object and
the 2 appearances are so confounded
that they cannot be seperated.
