An electric screw balloon, made by
Messrs. "A. and G.. Tissandier, has
made trial trip at Paris. The ex-
pertinent is stated to have been par
italy successful. although the arpar-
atus was powerless to prevent the spin
ming motion of the bailnOn when head
ing against the wind. Certain ini-
prnvemenis are 10 be made in the
elcctrOmotor Of the balloon, wien an

A new fuel, called "turi,ato,n is
now being made in Mexico. II con
sists principally Of beg peat, ullic!l j.
mixed with proper proportion OF
hitunlcn. The fuel is said to burn
freely and with little smoke, giving
more heat than wood and nearly rs
much rs the best bitumiilaus coal. II
can he sold in Mexico at lower price
than wood orcoal, as the ingredients
necessary for manufacture exists in

The danger Of iead-poiSoning to
which The use OF glazed eartiieFnWafe
may expose people has been pointed
ont in a communication 10 the French
Academy of Sciences. The glaze con
tains much lead, which is readily eN-
tracted by any substance thai IS al
lowed to ferment in the dishes. Free
dom from risk may be secured by
vanishing the glazed surface with
borosilicate Of lime.
Many cows in France are fed upon
beet-pulD. An Investigation into the
physiological effects of this food
shows that it causes the milk to in
crease in quality but deteriorate IN
