The pulse register Of DR.. Gartner, OF
Vienna, has proven berry successful In
lessening the surgeons work In watch
ing the circulation Of patients under
anaesthetics. 1t consists of a watch
like box, which is attached to the pa
tents forearm, and with hands that
are moved over the dial by sensitive
spring, very accurately showing the
pulse and blood-pressure vibrations. 1t
even reveals pulse action so feeble that
the finger cannot feel 1t.
The much-ridiculed name Of Liquid
crystals" is still retained 10y DIR. Otto
Lehman, who has published an en-
larged list of the organic compounds
having the peculiar properties. These
substances, as was first made clear
fifteen years ago, have two melting
points and at intermediate tempere-
lures move freely like liquids, but
polarize light like crystals and show
the dichroism of crystals. Whether
they are really like solid crystals is
still disputed.
In the survey of the Scottish lakes
which is now nearly completed, q
depth of 1,017 feet has been reached
in Loeb Moran. This proves to be the
deepest lake in the United Kingdom,
above sea level nearly the entire bed
of the lake is below the surface line
Of the ocean. Only seven deeper lakes
are known In Europe, four being in
Norway and three In Italy. At depth
of one thousand feet the temperature
of Loeb Moran is fairly constant
throughout the year at about AZ de-
grees.
Beginning with schools to teach
spinning by hand in the eighteenth
century, Germany has continued to
improve the instruction In textile in
dustry offered to its people with every
advance of practical science as applied
to weaving and spinning. Textile
schools, where the manipulation of the
most intricate machinery is taught, are
now found all over the empire, and Il
is held by some persons that they con
stitute the main pillar by virtue Of
which the German textile industry
maintains its competitive power II
foreign markets. The courses of In
, struction are frequently revised, ant
everything is kept up on scientific
basis.

ing-point is a fact of much praC
teal Importance because 1t serve
as a constant, or basis of comparison
in the measurement of high temperi

certaininging this point with exact

Messrs. Jacquerod and Perrot, usin
special type of electrical resistanc
furnace, and a nitrogen thernomete
of fused quartz. The melting poin
was found to be 1862 degrees cent
grade, or in round numbers about 105
degrees Fahrenheit. This is about
degrees Fahrenheit higher than som
former determinations, but somewht

Moved by the apparent loss Of tim

traditional use of Roman numerals

a ward has submitted the matter to

:. well-educated persons, he determine
= for each the time required for writir
and for reading the Roman and II
Arabic numerals from 1 to 100, al
also the relative number Of errors col

error is eight times as great An
