terested in an electrical method of re-
ducing the wood in the manufacture of

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
90, 900 to 40, 900 microbes arc found.
This number increases with time. Thus,
a acheese II days old contains 500, 900 bac-
terra per gramme. The population of
a soft cheese % days old and much
denser than the preceding is 1,20O, 600,
and that of cheese 45 days old is
1000, 900 microbes per gramme. - La

1t is we'll known that moths and
butterflies give off odors either from the
wings or tho hinder esd Of the body
Certain moths, as tho parent of the
red and black "bear" cater
pillar, and of the salt marsh cater
pillar, have a retractile organ which,
when thrust out, throws out a strong
odor, somewhat like laudanum. The
other evening we caught white female
miller (SpiIosoma otfyinica), 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 APP
pendages found in the other arctians.
