turned into solid concrete by blowing
into it through a tube by air pressure,
insures thorough mixture, and the
concrete formed in this way is very
satisfactory, though taking several
weeks to harden and requiring months
te attain full strength. It is found
that the mixture of the sand and
cement occupies less space than the
sand alone before the operation! This
method has already been successful in

R. j. Crosse has just registered a
trademark in Germany for new ther-
mometer, in which toluol is substi-

place, toluol is a liquid of a deep black
color, which renders the column very
visible; in the second place, the freezing
point of this liquid is very remote from
its boiling point, and, finally, it costs
less than mercury, and the manipula-
tion of it is attended with no danger to
the health of the workmen. Die Natur.
