Acetylene appears to be making
ronid nrogress as a mine lamp, one
German firm having recently placed
lamps in 17e different mines. lneeo
lamps are portable and designed u

NJ Phisalix announced in April l9ol
that young dogs, inoculated win at
tenuated cultures of cocco-oacillus
which he has named Pasteurella CAMS,
resisted the injection of the virus Oh
distemper and the direct contaglon OIL
diseased animals. He has continued
his experiments for year, and has IN
oculated more than 1900 young dogs
md his results show that distemper
can be prevented practically in every
case. NM. Joseph and Marcel LiS-
pieres have experimental along similar
lines and have arrived at similar con-
clusions.
An ingenious use is made of the COM
pressed air supplied to the workmen
in an East River caisson at New YORK
City. The caisson is being forced
down to the bedrock through a thick
stratum of sand. and it has been found
that the compressed air sent down 10
the men may readily be utilized to
hrive the sand up through pipes, in
stead of removing it by the tedious
use of shovels. The sand is pure and
loose, and jets of water are directed
against it at the bottom of the pipes
When thus dslodged it passes up
through the pipes with the strong air
currents produced by the compression
In the caisson.
In the Revue de Medecin Charles
Fere has an interesting article on hui
mar odors. He calls attention TO the
fact that the skin possesses certain
odor which varies much in individuals,
as well as in races. Dogs unquestion7
ably recognize persons largely by their
odors. Regarding the nervous origin
of these odors. Hammond cites the
case of woman who always gave out
an odor of pineapple when she was in
a temper. and another who smelled OF
violets when suffering from an hysteri-
cal attack. DR.. Fere cites a number of
cases of emotions produced by odors
reminiscent of certain events, and
finally states his belief that certain
odors are inherited or may even extend
to side branches of the same family.
A new process for making brick out
of sand and cement has been put in
operation in Missouri. No ovens or
burning processes are necessary, the
hardening of the brick beginning as
soon as it is taken from the mould and
in fifteen days it is ready for delivery.
During the process of moulding, a sim
gle brick undergoes a pressure of 65,-
900 pounds. In thirty days from the
time the hardening process begins, the
brick will stand pressure of ten tons;
in sixty days a pressure of twenty
tons. One special test on ninety-da
brick yielded a pressure of sixty-tlve
tons. The ordinary pressure required
for building purposes is about eight
tons. In addition, any desired color
may be produced by the introduction
of coloring matter into the sand and
cement mixture. When taken from
the mould the soft mixture must be
handled with eXareme care. The bricks
are then placed upon large racks built
for that purpose, where they are
sprayed with water from an automatic
sprinkler every four hours. This is
done to assist the action of the cement
in settling properly. The hardening
process naturally begin at the outer
surface of the brick and continues in
ward.
