Most people do not know q plant
has lungs, but it has, and its lungs are
in its leaves Examined through a high
power microscope every leaf will show
thousands upon thousands of openings,
infinitely small, of course, but each pro-
vided with lips which, in many species
are continually opening and closing.
insects generally breathe through
special pores in various parts of their
body, and if these pores are closed by
oil they are suffocated. Anyone may
test this by dropping sweet oil on the
thoraX or back of wasp; it very soon
dies. For this reason oil has been found
one of the best things to use for the de-
struction of insects.

milk Of cows which are more or less af-
teCted with tuberculosis everywhere.

/ Photographic mirage" Three years
ago NJ. Paul Roy photographed his

! veloping the picture found to his sur

Cats are not the only creatures thai
enjoy Il plurality of lives; many animal!
have remarkable power of existing
while apparently dead. Infusoria have
been dried, and restored to life by moist
ening after remaining inert dust fol
twenty-seven years, and the drying ant
| and resuscitation have been success
fully tried eleven times on one lot o
rotifers. Frogs and many fishes suffer
no injury from freezing solid while, il
= few cases, even warm-blooded ami
mails have been restored to life sftel
apparent death from freezing.
