SCIENCE AND INDUSTRY,

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 molding the
product into bricks or blocks of a con-
venient size to use for fuel.
1t is asserted by NJ. 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 ca.
not be distinguished by the naked eye.
In drug store at Spencer, Mass, q
package of the former was emptied into
a drawer of the latter, and in conse-
| quence woman was poisoned to death.
1t has been proved by Mr.. Waite's
experiments that highly polished
bearing is more liable to friction than a
surface finely lined by filing. 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 a 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.
ia 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 ci-
der had been kept long enough to turn
into vinegar had been before receptacles
in which boiled linseed-oil had been
stored, and the "hardN 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 little ele-
mentary knowledge of chemistry and
physiology.
The British MchcM J0ur7anI reports
an alleged recovery from hydrophobia
at PeshaWur. The patient, boy fifteen
years old, had been bitten by mad
bulldog, and to alleviate his sufferings,
his physician, DR.. John Buxton, of the
Army Medical Department, admins
tered tincture of Indian hemp. To the
Doctors surprise the boy awoke perfect
ly we'll after ten hours sleep The
facts are apparently reported upon suf-
ticient authority to warrant careful in
vestigltion and experiment on the part
of medical men.
The French authorities have decid-
ed tila' the use Of salcylic acid for pre-
serving food and drink is prejudicial to
he Nth. and have forbidden the sale of
articles 50 preserved. The use of this
sub stance 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 preventative agent must be added in
succe 'sivc doses till finally the ac.,umu-
lated quantity becomes so large a5 to be
inju iou'. Good articles of food or
drink do not require it, and the inferior
articles which are preserved with its
aid are sold cheaplv to the poor, and
they, as usual when the necess lries of
life are in any way fraudulently 'nrnipu-
lated, are the chief sufferers by I'll. ope-
ration.
