There is new project at Minneap-
oils to utilize the saw-dust thrown from
the saw.mills, by mixing it with peat,
grinding both, and then moldin9 the
product into bricks or blocks of con-
venient size to use for fuel.
1t is asserted by M. Hement that
deaf mutes who have been taught to
speak articulate with the accent of their
country, thus indicating organic confor-
nations of the mechanism of speech
similar to those of their parents.
--Oxalic acid and EPSON salts can
not be distinguished by the naked eye.
In drug store at Spencer, Mass, a
package of the former was emptied into
drawer of the latter, and in conse-
quence q woman was poisoned to death.
According to Prof. Young, the total
quantity of light emitted by the sun is
equal to $500, O00, O0O, 900, 600, 900, 0O0,.
O00, 900 candles. Such an array of fig
ures, however, seems meaningless, so
faint is human conception Of the num-
Der.
1t has been proved by Mr.. Waite's
experiments that highly polished
bearing is more liable to friction than a
surface finely lined by fling. The lines
left by the file serve as reservoirs for the
oil, while the high polish leaves no room
for the particles between the metal sur
faces.
Cotton adulteration continues to
receive considerable attention, and to
create not little excitement in Oldham,
England. 1t is asserted that limited
company, which has had considerable
consignment Of American cotton, deter
mined to test how far damp had been
employed, and it was found that on be-
ing dried the cotton lost seven per cent.
in weight.
Not few cases of lead poisoning
have taken place in Fairfax County,
Conn. They occurred in this way. A
good many of the barrels in which CT
der had been kept long enough to turn
into vinegar had been before receptacles
in which boiled Inseed-oil had been
stored, and the "hard" cider had dis
solved some of the litharge or oxide OF
lead which had been deposited on the
inside of the barrels. This was rather
an expensive way Of gaining a little ele-
mentary knowledge of chemistry and
physiology.
The British Medical Journal reports
an alleged recovery from hydrophobia
at Peshawur. The patient, a boy fifteen
years old, had been bitten by mad
bulldog, and to alleviate his sufferings,
his physician, DIR. John Buxton, Of the
Army Medical Department, admins
tered tincture of Indian hemp. To the
doctors surprise the boy awoke perfect
ly well after ten hours sleep. The
facts are apparently reported upon suf-
ficient authority to warrant careful in
vestigation and experiment on the part
of medical men.
The French authorities have decid-
ed that the use of salicylic acid for pre-
serving food and drink is prejudicial TO
health, and have forbidden the sale OF
articles so preserved. The use of this
substance has become quite extensive,
especially in wine, syrups, beer and
milk. The danger lies in the fact that
in order that the preservative effect
shall continue for any length of time,
the preservstive agent must be added In
successive doses till finally the accumu.
lated quantity becomes so large as to b
injurious. Good articles OF food OF
drink do not require it, and the inferior
articles which are preserved with its
aid are sold cheaply to the poor, and
they, as usual when the necessaries a
life are in any way fraudulcntiy manipu.
lated, are the chisf sufferers by the ope-
