The smallest vibration Of sound can
be distinguished better with one ear
than with both.
Only one person in FIFTEEN has per-

The primary cause of sour milk is
the growth OF certain bacteria that are
always very numerous in the air and
cannot be kept out Of the milk. These
are most abundant during damp, heavy
weather, which usually accompanies
thunder storms, as such weather is
particularly favorable to their Develop
ment Hence. the popular notion that
thunder storms make milk sour.
A testing apparatus for varnish,
! supplying a needed standard. has been
brought out in Scotland by Professor
Baily and DR.. Laurie. 1t includes d
blunt steel point pressed down by a
spiral spring, and this point is drawn
over dry coat of the varnish On glass,
the pressure being increased until
the varnish is scratched. The pressure
being known, a definite measure Of
the ioughness and hardness of the var
nish is made available.
Liquid air blasting cartridges, as de-
scribed by n. lacquer, are made by,
packing powdered charcoal in a case
of stout paper, and covering this with
an asbestos wad through which al
paper tube passes to the bottom Of
the cartridge. When ready to USE,
liquid air is poured into the tube, the
cartridge being fired by illuminate
cap in the usual way. The firing should
follow the filing within ten minutes,
as the liquid air gradually evaporates.l
Mr.. W. E. Scarritt. formerly presi-
dent of the Automobile Club of Amer
lea, says, in Casters Magazine, that
he expects in the near future to see,
very fair runabouts sold for $500, and
touring cars Of a similar grade for.
$500. He also predicts that in time
prices will be still lower, so low. in
deed, that the average city workman
will be able to own his own automobile,
as he now owns his bicycle, so that
he can keep bis family in the country,
and ride to and from his work.
Why the teeth of some people decay
early while those of others continue
sound throughout a long life is prob
lem that appears to have been only i'm
perfectly solved. a European investi-
gator, DR.. G. Risa, has lately Analysed
the saliva of 219 children. averaging
thirteen years of age, and has con-
frmed, the idea that there is rela-
ton between the alkalinity of the sal
iva and dental carries A highly aka
line saliva insures good teeth He has
made many experiments to determine
how an acid or slightly alkaline saliva
may be made decidedly alkaline, and
has proven that diet containing much
lime has marked influence. and does
much to keep the teeth in perfect con-
dition.
Cheap oxygen is the one important
product thus far obtained from liquid
air, for which such extravaganza prophe-
cies have been made. AS the nitrogen
and oxygen of the liquid air return to
the gaseous state at different temper
atures, it has proven to be possible to
separate them by fractional distilla-
ton, and as the evaporation of the
gases cools the air entering to be COM
pressed in the apparatus, the process
is very economical. An idea of this
efficiency has lately been given by M!
Georges Claude. Els plant produces
one thousand cubic metres of oxygen,
with a purity of ninety-six to ninety
eight per cent. in twenty-four hours
and the cost in France is only one
twentieth of that of oxygen from the
electrolytic decomposition Of water.
