"A color test for railway employee
has been introduced in the shape of a
device consisting of revolving series
of colored glasses lighted from behind
by a flame and tinted like the lamps of
the signal boxes.
Cinnamon are making money in
California by going over stacks of straw
abandoned by farmers and clearing out
the mustard seed in it. One Chinaman
will save one hundred pounds or more a
day, and make better wages from what
the white man throws away than
farmers have made from their grain
crops.
The spread of cancer in a small.
commune of Normandy (St Sylvestre de
Courselles) attracted the attention Of
DIR. Arnaudet, as the disease had at
tanned to fifteen per cent. of the total
mortality The cases were principally
males, and as rule the cancer was To-
Gated in the stomach: hence DR.. Arnau-
Diet thinks that cancer is contagious, and
is prOpagated by water.
The fast fishes, according to Prof.
6. B. Goode, are of pointed build with
close-lying fins, and are frequently pre-
dacious. Food fishes, on the other hand,
are often slow, and easily caught, but
are CORRESPONDENCE prolific. The actual
speed of fishes is not as yet well known;
but as dolphins have been observed to
swim round and round steamer going
at full speed, their pace is estimated at
twenty miles an hour or more.
Quicksilver ore in layers was discov-
cred in the year 1879 at place called
Nikitowka, in Russia. 1t is a station
on the sk-Charkow-ASOw railway.
In 1885 company was formed for work
ing this ore, and work commenced in
the following year. Thus, since April,
1886, or Whereabouts, the production of
quicksilver has become new branch of
mining industry in that country, which
promises to give fairly satisfactory re-
suits.
Every one knows that daltonism
consists in color blindness in regard to
certain hues, says the Transatlantic.
According to the researches of DR.. AL
bertini, this daltonism is accompanied
by corresponding deafness toward GER
tain musical notes. Those persons who
have not the sensation of red can not
distinguish the note sol; those blind to
green can not recognize re; and to this
lack of perception in hearing is added
the incapacity to produce the notes men
toned by means of the vocal apparatus.
In Chemnitz, Germany, weavers of
ticking get 81. SO per week, fustian weav-
ers So, sewers $I.25, corsetmakers twenty
to twenty-five cents per day. At Bremen
male weavers earn from So to So. 70
week, women at $1.25 to SO. In Silecia
the average falls to twenty-nine cents
per day. Berlin engineers make from
seventy-five cents to 81 per day. Work
ers in glassware and porcelain make less
than seventy cents per day. These
figures are from a report of the Chem
nitz Chamber of Commerce.
Inquiries have been made as to the
nature of the natural concrete called
''teIeteta," which has been referred to
in our Mexican correspondence as being
used extensively for station and other
railway buildings on the Mexican lines.

by the action of water and paessure been
cemented into beds of wide area. 1t is
quite soft, being readily cut with saws
into any shape desired, thus making it
cheap building material. -Railway Re-

Prof. Won Bergman, of Berlin, is
reported to have performed remarka
BILE surgical operation. Two patients
were simultaneously brought to him for
operations, one requiring ampu tation of
the thigh at the hip joint, the other
needing a portion of the humerus re-
moved on account of the bone being ex-
tensively diseased. the first operation
was the amputation, and then the sur
geon proceeded to excise the diseased
portion of the humerus. This made
gap in the bone, but piece of the thigh
bone was taken from the limb which had
just been amputated and fixed in the
gap, by which the continuity of the hui
merus was completely restored. Perfect
union took place, and the patient re-
covered with useful arm.
