sci TO have three kinds of motion; a
rising and falling motion of the entire
vessel; an oscillating motion longitude
nally about its centre of gravity; and
transverse rolling motion. He sup
poses the longitudinal motion to have
tendency 10 drive matter centrifu-
gally toward the head and stern, and
the rolling motions similar tendency
to drive matter outward from the cen
tire of such motions The entrance to
the stomach is on the left side of the
body, the esopbagus end, and the exit
is on the right side, the pylOric orifice;
and his experiment consisted in util-
izing the longitudinal motions so as to
keep the food in the stomach, and the
rolling motions so as to assist the nat
ural operations of the esophagus in
propelling the food toward the pyloric
orifice. This is effected by lying upon
the left side, with his head toward the
engine room, on a couch arranged on
line with the keel. With suitable
berth, the ex pertinent has been invar-
ried out with berths arranged athwart-
ship.
1t is now known that no place is
free from earth movements of various
kinds which may be recorded if not
felt. Professor John Milne and other
seismologists propose an earthquake
survey of the world, which would
show interesting facts concerning To-
cal movements, but which would have
for its chief object the measuring of
propagation of earthquake motion
through the crust of the earth, or pos
sibly through its interior. This would
be effected by study of the time rec
Ords of disturbances originating some
thousands of miles away, or even-as
in one known instance at least-on the
opposite side of the globe 1t is sug-
gested, that fifteen observatorIes he es-
tablished, and these, if suitably located
for recording the waves from three dis
tricts of frequent earthquakes, would
nearly all be in the United States or
the British colonies, and about 1000
miles or nIultiples of 1000 miles dis
tant. The three earthquake districts
are the South American coast, Japan
and the Philippines, and Himalaya
and Central Asia.
Right-handedness, which is found
to have eNisted in the majority of man
kind from the earliest times, is traced
by DIR. ID. g. Brinton to the erect pos
ture. The apes most resembling man
are amDidextrOus, displaying no pref
erence for either hand, but the erect
posture opposes the powerful retarda-
ton of gravity to the distribution of the
arterial blood above the level of the
heart and thus introduces new dis
tribution of force in the economy.
The great arteries arising from the
aOrta carry the blood in an appreciably
shorter course, and in less time, to the
left brain than to the right. Its nutri-
ton being therefore the more abun-
dant and its vitality the more active,
the right side of the body, which it con.
trolls, is more ready to respond to any
nerve stimulus
A mysterious disease of fowls, which
appeared III Rome some months ago
and has had mortality of 90 per cent,
has been investigated by DR.. Salverio
Santori. The result has been the iso-
lation of new micro organism, which
belongs to the class of pigment-pro-
ducing bacteria, a class rarely associat-
ed with disease. The splendid red
color is elaborated only i'm the air and
at temperatures below 100 degrees F.,
although the organism grows album
dainty under other conditions. The
microbe is very virulent when subcu-
taneously injected, but quickly loses
its power in artificial cultures, ali hough
its virulence may be preserved ON silk
threads that have been soaked in the
cultures and dried. Gradually increas-
ing doses of the toxine gave no immu-
nifty.
A colossal statue of st. Fedele, Just
erected on a tower in Palazzolo, Italy,
is 33 feet high, but weighs only 1860
pounds. Had it been cast in bronze,
its weight would have been at least so
tons. The work was modelled in clay,
mould was prepared in plaster in sew
enteen principal parts, aud thin shell
Ofcopper was deposited on these by the
electrOlite process, the various pieces
being afterward joined by soldering
into five main sections for shipment,
and these sections being finally placed
upon a timber framework and fastened
together with screws. The electro
metallurgical work was done in Milan,
sufficient current being supplied by a
dynamo aud a five-hOrse power gas
engin.
The chemists test for acids and al
kalies is now supplied in the form of a
pencil, which is simply the ordinary
wooden rod with a core of chemically
pure red and blue litmus instead of the
usual grophite core. The litmus pencil
is said to be SO sensitive that it will de-
tect one part in 100000, whereas litmus
paper can only detect one part in 400.
The air of badly ventilated rubber
factories becomes so charged with car
bon birulphide-an exceedingly vola-
tile sOlvent-as to give rise to peculiar
symptoms of poisoning. In three pa
tents lately shown in Germany by DIR.
Stadelman, giddiness. headache, trem-
Ors, drowsiness, loss of energy, and
gradual impairment of vision appeared
after work for few weeks in this at
mosphere. One patient became affect
ed with yellow sight and cloudiness of
vision, and also with painful contrac-
ton of the muscles and difficulty
in standing and walking. Another
