wrapped in tissue paper so that no air

paper will soon be on fire.
Paper ties are said to have numerous
advantages over the ordinary ones. be-
ing lighter, harder, and a.so impervious
TO damp. Furthermore. they are nom
conductors of heat and sound. and look
better than the old kind.
Glass library shelves have recently
been introduced in France The edges
,re rounded. The glass is nearly in
flexible, which gives 1t great advant-
fge over wood. Its strength has been
proved. 1t is more easily kept c.ean
than other shelving. The appearance
Of the library is greatly enhanced. The
book people who have used it are en-
thusiastic.
Sudden and great fluctuations In the
level Of water In wells in stormy wealth
er. closely corresponding to the iuctua-
tons In wind velocity recorded by Prof..
Langley, have been observed by Dr..
Eomei Martini. This explains the pop
rIar tradition that bad weather may be
predicted from the sudden rise and fall
OF wells. Curiously. however. small
and rapid changes OF barometers are
more certain to affect wells than largo
changes.
Recent observations on the diner-
ences of color in different races Of men
sre described in a French journal OF
j anthropology by Monsieur Breul. 1t
appears that the color of the skin de-
pends upon a pigment contained In the
deeper layers Of the epidermis. This
pigment, In the form of minute grains.
is distributed in the same manner In all
races, 3 only difference being in the
color of the grains, which varies from
back. through many lighter shades. up
TO light yellow.
In Spain, wnere the telephone is .arge-
1y used in place of the telegraph, says
Monsieur Plerard, as reported In the
Electrical World, 6n ingenious app.i-
cation Of the phonogrs oh to record the
telephone messages ha.s been made.
The receiving operator repeats the mes
sage into a phonograph, from which 1t
can afterward be transcribed at leis-
ure. This saves the delay caused by
writing the message during its recep-
ton, and insures greater accuracy be-
cause the repetition OF the message for
the phonograph Is heard, simultaneous
ly, by the original sender At the other
end Of the line.
Many Of tho violent changes which
,ccur under the surface of the sea, as
Prof. John Milne has recently shown.
produce effects that are distinctly and
sometimes disastrous,y felt on the land.
Wherever a profound cavity exists in
the bed of the ocean near tue land. and
wherever the border Of a continent
slopes off into a deep sea, great slides
are apt to occur, and these often cause
earthquakes. In Japan, Mr.. Milne says,
a large number of earthquakes came
from the deep sea OF the mouth Of the
Tonegawa, the largest Of the japanese
! rivers The river brings down alluvial
detritus which Is deposited on the brink
Of a deep hollow in the ocean. and from
time to time the accumulated deposit
sides into the depths, shaking not only
.he sea-bottom, but the adjacent land.
According to Nikola Tesla, ~ report
ed In Industries and Iron, "of all con-
ceivable methods Of generating electri-
cal energy, notA in the present nor
In the future Is likely to compare in
facility and economy with the water
fall" OF all methods of generating
power, the utilization Of waterfall, he
says, Is the simplest and least waste
ful. According to him, even II it were
possible, by combining carbon in a bat
terry, to convert the work Of the chem
ical combination into electrical energy
with very high economy, such mode of
obtaining power, he thinks, would be
no more than q mere makesmift, bound
to be replaced sooner or later by a more
perfect method which requires no con-
sumption Of any material whatever.

ed after three months experience. He
uses fine thread gloves, which are made
aseptic in steam in the same way as
surgical bandages. OF course the hands
are washed and disinfected in the usu
al manner before the gloves are put on
-Ehe gloves have to be changed severa
times during long operations; they are
worn by the assistants as well. Prof
Mikulicz declares that none Of the man
ipulations are rendered awkward ol
difficult by the gloves, and that. on th'
contrary, 1t is easier to take and keeI
hold Of tissues in gloves than with tn,
bare hand. He further recommend

: lin, in order to avoid danger from
