Observations in the Atlantic give
from fortyfour feet TO forty-eight feet
as tue highest measured waves. But
such heights arc rarely reached, and, in
deed, waves exceeding thirty feet are
very seldom encountered.
A writer in the St. Louis Glols- Demo
erIt is looking hopefully forward to the
time When the walls, ceilings and floors
of our dwellings will be Of malleable
glass as period when approximate
cleanliness will be possible
A Vienna engineer has Just taken out
patent for a new smoke-abating pro-
cess. BY means Of electricity he pro-
poses to condense the solid part of the
smoke as it arises from the coal, the
carbon thus formed falling back into the
furnace.
Professor I,eclerc maintains that odors
are due, not to the emanations, as such.
OF sO-called odoriferous bodies, but to
the vibratory movement among such
emanations, due to processes of oxida-
ton. Scent, on this theory, is analogous
to sound.
In drilling glass, stick piece of stiff
clay or putty on the part where YOU
wish TO make the hole. Make a hole in
the putty the size you want the hole,
reaching to the q ass, OF course Into
this hole pour a little molten lead, when,
unless it is very thick glass, the piece
will imme diately drop out.
Two French biologists have been max
ing experiments in typhoid fever vacci-
nation. In mice inoculated with cultures
of typhoid bacilli genuine typhoid fever
seemed to be produced, but in nice IN
oculated with broth in which the germs
had lived but no longer containing them.
subsequent inoculat on with the mostin-
tense typhoid virus was resisted.
Heavy machinery is now run by
srtesian we'll power in many parts of
France, and the experience of the French
shows that the DEEPER the well the great
er the pressure aud the higher the tenn
peratare. The famous Grenelle well,
sunk to the depth of 1900 feet, and flow
ing daily some 500, 600 gallons, has
pressure of 80 pounds to the square inch,
the water being also so hot that it is used
for heating the hospitals.
The remarkable substance known as
poteline is formed by mixture of CIV
cerine, tannin and gelatine, to which
may be added the sulphate OF baryta or
zinc-whi,e; the resulting mass may be
colored by the addition of vegetable
colors. While poteline Is hot 1t can be
nodded, and when cold it Is susceptible
OF every kind Of manipulation. such as
turning. filing, boring, etc, aud takes a
very fire polish.
Nearly twenty years ago DR.. WiIks
directed attention to the fact that
transverse furrow appeared ON the nails
Of the hand after a serious illness. Med
zeal literature has since then contained a
few references to the subject he again
brought the subject before the Patho-
logical Society at its meeting on March
20, and related a remarkable case. In
that case the furrow was caused by three
days sea-sickness.
OF the present very limited number OF
high stations for making meteorological
observations. there are only two in Eu-
rope which exceed 5000 metre- in height,
being about 10, 900 and n. 001 feet re-
spectiyely. Among those in this coun-
try Pixies Peak, which has an altitude
Of "A, 600 feet, exceeding thus, by more
than 5000 feet, any in Europe These
great heights are much more accessible
on this continent than in Europe, there
being five in America where J.. 900 feet
or more IS reached by railroads built for
mining work.
By means Of recent improvements made
in the manufacture of rifles. as many as
one hundred and twenty barrels can now
be rolled in an hour by one machine
They are Strengthened cold and bored
with corresponding speed. and even the
rifiing is done automatically so that one
man tending six machines can turn out
sixty or seventy barrels per day With
the old rifing machine twenty barrels
was about the limit OF days work; but
the improved machines attend to every
hing after being once started, and,
when the riliing is completed, ring a
bell to call the attention of the work
