SCIENTIFIC GLEANINGS.

Fort Keogh, Mon, has the widest range
of temperature of any place on earth. Last
summer the thermometer ranged from
100 to 40 degrees above, while it has
marked IS degrees below zero, total
range of 1875 degrees.
Frozen milk, it is asserted. may be kept
in a fresh state indefinitely, and many
steamers sailing on distant voyages are
now provided with steam refrigerators, IN
which milk and other goods may readily
be preserved for any length of time.
Paris doctors have condemned the sac
charine or artificial sugar produced from
| coal. because it seriously troubles dlges-
| ton. They recommend that it be prohlb-
| tied as an article of food, and a law to
effect it, we believe, has recently been
enacted.
La Nature describes and illustrates a
remarkable form of earth worm which Is
| found in Australia. They are one and
quarter inches in diameter, and SIX feet IN
| length, and exhale strong odor analogous
| to that of creosote.
A free application of soft soap to a fresh
| burn almost instantly removes the ire
from the flesh If the injury is very severe,
as soon as the pain ceases, apply llnseed
| oil. and then dust over with hne flour.
| When this covering dries hard. rel eat the
| oil and -four dressing until good cOatlng
| is obtained. When the latter dries allow
| it to stand until it cracks and falls off. as
| it will do in a day or two, and Il new skin
will be found to have formed where the
| skin was burned.
| In generating steam, experiments under
1 various boilers show 900 feet of gas to
| equal in heating power to from eighty to
1873 pounds of different kinds of coal. One
| pound of coal equals in value ~ feet of
| natural gas. and the latter explodes violent
| ly when mixed with nine to fourteen parts
| of air. When burned with pure oxygen,
| the flame temperature of the natural gas Is
estimated at ZOO degrees c.
An ingenious means of repairing a
| break in a steam pipe consists IN binding
| the break with wood strips laid close to-
| gether, and well served around with stout
| cord or rope, endwlse separation beng
| prevented by more rope crossing the break
| diagonally, and tied so as to draw the
| broken parts together; on the wood and
the cord getting wet with steam the joints
become even tighter than before, as the
wood swells and the cords tighten.
NJ. Ungerer, a French scientist, believes
the flowers and the perfumes distilled
from them have salutary influence on
the constitution. and indeed may be re-
| garded as therapeutic agency OF high
| value. He saws that residence IN a per-
fumed atmosphere forms protection from
| pulmonary affections and arrests the de-
| velopment of phthisis. He adds that IN
| the town of La Grasse, where the making
| of perfumes is largely carried ON. phthisis
is rare. thanks to the odOrous vapOrs eN-
hailed from the many distillerles.
An important experiment has been tried
| successfully at Ottawa, Ont. mill has
been established which makes paper pulp
| ont of sawdust 1t is now using all the
! product of one mill. The paper made
wholly from sawdust is said to form an add
mirable sheathing that is fit for building
after being tarred and dried. better
| quality is made by using one-fourth waste
| paper The plant costs $4,000 and con-
| sists of American machinery with the ex-
ception of the grinders. The mill has a
| capacity of converting about l2,OOO tons
of sawdust into paper annually.
| According to a correspondent of the EleC-
! trical Review. Mr.. Edison believes that the
| time will come when transportation
through the air will be the order of things
IN that line. The idea that the air ship
mus 90 up mile or more is erroneous. If
it we're no higher than an ordinary build
ing il would suffice. When the time
cones tcr it to be put in operation" he
sad, there will be one drawback to it,
and that is the ease which it will afford
/ criminals to make their escape from what
ever point their crime was committed.
There will be no danger of their being in
| terrupted by wire, as is the case now. 1t
may be that the same science which will
| give us this sort of navigation will provide
something else by which criminals who
make their escape through the air. will be
overtaken. But this will take time.
In my opinion, when we shall have
aerial navigation we shall see more
crime.
