SHIPS OF SCIENCE.
IT Is reported in Engineering that
LaurlstOn House, Bromley, England,
the residence Of Mr.. Swan, the inventor,
is lighted throughout with electricity in
most complete manner. Every room
and closet within the house, to the very
coal cellar, can be lighted at Will. If
person wishes to enter bedroom, for
instance, the movement of a switch il
Eliminates 1t before be opens the door,
and then when he comes out he can as
easily make the room dark again. The
httlngs, from those of the gate lamps TO
those of the drawing-room, are most
deliberately and artisticaliy designed.
IT is reported ia Van Nostrand's En-
glneerlng Magazine that firm N Paris
has patented an invention for the in
Simultaneous formation Of steam, so that
1t can be used at once in the cylinder of
the erglne. A pump sends the re-
CURED quantity Of water between two
plate surfaces, which are heated, and
between which there is only capillary
space. The liquid spreading into a thin
layer eVaporates instantly, without
going into the so called spheroidal
state, and the steam acts in the cylinder
as fresh formed steam. The speed of
the pump is regulated by the engine.
Ar a late meeting of the Anthropolog-
lcal Institute, London, DIR. John Rae
exhibition one Of the lamps in general
use among the Esqulmaux for warming
their dwellings and cooking their food.
1t was made of steatite. The shape was
that OF fat, semicircUlar dish Is inches
IN diameter and % inches deep, with
slightly sloping sides. Oil is burned in
this lamp, and for wick pieces Of sphag-
mum are arranged arouud the edge. DR..
Tylor remarks that the metal lamps
used at the present day IL some parts of
Scotland and the south Of Europe are
the same in principle and grew out Of
the Identical original idea.
A LITTLE more than a decade ago
new disease began TO despoil the potat
near Stavanger, Norway, and It has
been steadily increasing IN ylrulence
year after year. Fungoid growths infest
the stem, reducing its interior in the
first place to sort of pulp, and at last
so prey upon the plat tha the stems
are mere hollow reeds viii n readily fall
to the ground. The ripe germs Of the
fungus are about the size of a small
bean, and when they remain In the
earth all winter they are found when
the warm season commences sending out
minute spores, which attack the plant
before 1t shows itself on the surface.
The ravages of this pest are most mark
ed about the end of July and the begin
ming of August.
THE Cheyalier Frederic Franchetti,
engineer at Leghorn, says the Nature
| has referred NJ. de PIville to a curious
passage IN Galleo's - Dialogues, touch
ing a possible early origin Of the cleo
trIc telegraph. IN the dialogue Sagra-
do says that he calls to mind a man who
wanted to tell him a secret which would
give him the power by means OF Ger
tain sympathy Of magnetized wires to
speak to any one 1900 or 5000 miles
off. The bargain, however, fell through,
| as the inventor wouldnOt try any shorter
distance, and Sagrado declined to 60 to
Cairoor Muscovy to try the experiment
| The story is told IN the last number of
| the BeUue Scientifgue. The reference
given Is page 81 of the First Day
LeghOrn edition, 1874.
SPEAKING Of the American trotting
horse, Mr.. F. Z. Nipper says that it is
! very probable that the trotter Will final
ly surpass the running horse. Besides
mathematical evidence, he advances the
/ following: The trotter carries his body
more steadily-with less OF rise and fall
| than the runner, and it seems very
| reasonable that this should result to the
! advantage of the trOtter, when the pro-
| cess of developing and adjusting his
/ muscles and chest shall have been suf-
| ficientiy carried on, so that the contest
! between the two animals shall have been
| reduced to a matter of muscular capac
! lty. He concludes that it Is very cvl-
! dent now that our good ancestors who
| thought it wicked to run horses. builded
more wisely than they knew when they
began the evolution of the American
trotting horse.
SOME remarks We're made recently by
| NJ. q. Lagne6U on certain differences
between Roman Catholics, Professionals,
and Jews as to the relations among them
of deaths and births. These were sup
Elementary to previous observations.
Statistics show that Catholics viewed
broadly, with a gener lily higher b1th-.
rate, have a considerable death-rate. re-
sulting in a corresponding feeble in
crease of population, while among Prot
estants this increase is often much high
er, notwithstanding a somewhat smaller
natality, which, however, is corrected by
lower infantiIe mortality. To both Of
these statements some individual ma
tionalities present marked exceptions.
It is found that the jews increase much
more rapidly than either of the other
two religious bodies Although the ma
tahty of the Jews is less than either,
their mortality is remarkably low for all
ages-a condition of things due prob
ably to the religious, dietetic, and by
gienic regulations, the lpfrequent occu.
patton of their women out of their
homes, early marriages, and general so.
