has been led TO make this innovation
In the desire TO increase the efficiency
OF a vessel. without at the same time

stead Of designing the hull somewhat
after the form of a fish, has taken as
his model an aquatic bird. which. like
The ship, makes its way along the sur
face of the water In his design the
ships hull has the shape Of a tetra-
hedron or double wedge BY this
means IL is anticipated that the eff

30 percent. Another great advantage
Is that such vessels will have no wash
Several interesting experiments
have been carried out by the Austrian
army to obtain reliable data relative
to the possibility of disabling a bal.
loon wnen floating in the air By eth
er rifle or gun fire. For the purpose
Of the experiments a balloon was an
chored at the height Of about 1000
feet, and the gunners, kept in igno.
rance of the range, were then COM
manded to disable the balloon. The
difficulty of hitting the balloon when
in mid-air can be realized from the
fact that the gunners fired % shots be-
fore the approximate range was found,
and that it was not till the sixty-fourth
round that the balloon was hit, and
then only slightly The small tear in
the gas bag however, was sufficient
to cause the balloon to descend slew

Pneumonia Qung fever) having be-
come of late years the most deadly
disease at all ages, general intelli-
gence in regard to its cause and what
may be done to avoid it is desirable.
The disease depends upon a specific
vegetable organism, which, being at
all times present in thickly populated
districts, grows rapidly in the air pas
sages of the individual if his vitality
is suddenly depressed. In these par.
ticulars the bacillus Of pneumonia re-
sembles that Of consumption, but it's
multiplication is much more rapid and
the poisoning from it's excretions
much acute. The danger of pneu-
monia may be lessened by keeping the
air passages clear of mucous, by
avoiding chill and fatigue, by good
ventilation and absence from crowd
Cd and overheated rooms.
C. Delezenne finds that the venom,
both fresh and dried, of the cobra, the
adder and the puff adder, all contain
peculiar ferment, a kinase, which,
although itself without proteolytical
action on albumin, is able to impart
to pancreatic Juice very powerful d.
! gestive action on that substance. This
! ferment is entirely destroyed by heat
ing the venom to 100 degrees G. for Is
minutes. The poison of the puff ad.
der is the most active in this respect,
0.5 to l mgm. of the venom being
sufficient to enable c. c. Of pancreat-
ic juice to digest so Gym. Of albumin
in ten or twelve hours. Cobra poison
was found to be slightly less active in
this respect, while that of the viper
had a marked lower proteolytic action,
five or 10 times more being requisite
to produce the same effect. The kin.
