Pulp manufacturers are deeply in
terested in an electrical method of re-
dncing the wood in the manufacture of
pulp. BY this process it is claimed that
the fiber is manufactured so cheaply
that tho entire pulp business will be
rcvelationized, and the digesters now In
use be driven out Electrical Review.
The influence of the electric arc on
vegetation is said to have been striking
ay shown in Berlin in the spring OF this

branches under the electric light dis
played new leaves of considerable size

reasons for disseminating business were
lack of funds, differences OF opinion
among members, and dwindling away
of membership.
Mr.. Adametz has just made some
microscopic researches upon the micro
scopic organisms that inhabit cheese.
From an examination of Emmenthal, a
soft variety of Gruyere cheese, he has
obtained the following results: In each
gramme OF the cheese, when fresh, from
10000 to 10000 microbes are found.
This number increases with time. Thus,
achecse II days old contains 500, 900 bac-
terra per gramme. The population of
a soft cheese s5 days old and much
denser than the preceding is 1000, 600,
and that of cheese As days old is
1000, Qo5 microbes per gramme. - La

1t is we'll known that moths and
butterflies give off odors either from the
wings or the hinder end of the body
Certain moths, as the parent of the
common red and black "bear" cater
pillar, and of the salt marsh cater
pillar, have a retractile organ which,
when thrust out, throws out strong
odor, somewhat like laudanum. The
other evening we caught white female
miller tSpilosoma rirgiaica), which, after
rough handling, threw off very pecu-
liar strong odor, somewhat reminding us
of laudanum, and which remained on
the fingers for several hours. The moth
did not dart out the repugnatorial ap-
pendages found in the other arctians
