That eggs decrease in weight during
incubation has been proved by careful
weighings by II. S. Gladstone. The
average loss of a pheasant's egg from
the first to the twenty day was
found to be two drains twelve grains,
and one egg which weighed seventeen
drains nineteen grains when laid had I
become reduced to thirteen drains ten
grains on the twenty-third day.
A striking instance of the change
which the cultivation of natural
science is capable of causing in the
face of the earth is afforded by a re-
mark of Andrew Murray concerning
the result achieved by horticulture il
England. They have, he said, affected
the appearance of all England. NO
where can a days ride now be taken
where the landscape is not beauti-
fed by some of the introductions of
the Royal Horticultural Society,"
There are bacteria and bacteria.
DR.. Charrin, a French Psychologist,
has been experimenting upon rabbits
with various vegetables sterilized by
the most approved processes, and he
udS SHOWN lldl IL Is eTIOUeOuS W ue-
clare that the less bacteria there are
in our daily food the better. What is
required is to weed out the harmful
organisms from the beneficent kinds.
The rabbits fed on sterilized food soon
died from maladies set up by non
assimilation of the vegetables, but 9th
er rabbits fourished on similar ster
ilized vegeta bles that had been after
ward treated with suitable bacteria.
Much interest has been awakened
by the experiments at Lyons in feed
ing silkworms with leaves stained
with various dyes in order to cause
them to spin silk of corresponding
hues. When fed on red food the
worms spin red cocoons, and the silk
| seems to retain the color The eXpe-
riments with leaves stained blue have
been less successful. Although the
expectation has been raised that this
process may prove of commercial i'm
portance, the experiments say that
they do not expect to make any dis
coveries which will affect the indus
try of dyeing.
