Dr. J. Miner Fothergill predicts great
future for malt as a food. Among other
things, he commends lemonade made with
malt instead of cane sugar.
A gigantic crystal of spodumene found
in Dakota measures, according to Prof.
Blake, thirty-six feet in length and from
one to three feet in thickness.
Acting on scientific suggestion that
neutral tints are beneficial to the eyesight,
an enterprising German publisher has just
issued book printed in dark blue ink on
pale green paper.
In Paris remarkable success has attended
experiments in photographing the country
from captive balloon. The operators re-
main upon the ground, and open the valve
of panoramic object-c class by means OF
an electric current.
In the last volume issued by the Geologi-
cal Survey of India is an account of fiery
eruption from one of the mud volcanoes
on Cheduba Island. A body Of flame COO
feet in circumference is said to have at one
time reached an elevation of 24OO feet, Pc
troleum being the cause.
DIR. Phipson advocates, in German
scientific journal, the general use Of sugar
as regular article of diet. For forty years
he has eaten at least a quarter of a pound
daily, not counting sugar-forming sub
stances taken at the same time, and has
found it very healthfui. ] Mems gcondition
would be greatly improved if the use of
sugar should substitute that of alcohol.
Experiments reported to the Paris Acad-
envy of Sciences prove that the pressure
necessary to cause the rupture of blood
vessels is very much greater than that to
which they are normally subjected. The
carotid artery Of dog required from
thirty five to fifty-fve times the normal
pressure of the blood, and the jugular vein
from thirty-tvo to thirty-five times the
usual force. ~
A reputable scientific authority quotes
the statement that, by careful estimate,
spider ate four times its weight for break
fast, nearly nine times its weight for dinner,
thirteen times its weight for supper, finish
ing up an ounce, and at P. NJ, when he was
released, ran off in search of food. At
this rate, man of 1GO pounds would re-
quire the whole of fat steer for breakfast,
another with half dozen good sheep for
dinner, and two bullocks, eight sheep and
four hogs for supper, with about four bar
rels of fresh fish as lunch before going to
his club banquet.
The dental processes familiar to US are
not 50 new as may be supposed. In the
museum of Corneto, on the coast of Italy,
are two curious specimens of artificial
teeth found in Etruscan tombs probably
dating 400 or 500 years before our era. The
teeth were evidently taken from the mouth
of some animal, and had been carefully cut
and fastened to neighboring natural teeth
of two young girls by means of small gold
rings. The dentists art was also applied
to treating natural teeth in various ways,
but the fact has hitherto escaped notice on
| account of the rarity Of Etruscan skeletons.
Some time ago the discovery was made
| by Mons. Oh. Montigny, by means of a
beautiful instrument called the scintillom-
eter, that bluel largely predominates in a
twinkling of tile stars when there is much
water in the atmosphere, and that the pre-
ponderance of green or of violet is indica-
tive of great dryness. A late series of tables
by this Brussels savant indicates that he
has hit upon law by which wet or a dry
season may be predicted with great cer-
tainty., Perhaps the best test Of the sound
ness Of his views is found in the fact that
his scintillometric forecasts of the increas-
ing drought IN Belgium of the years 1883
and 1884 we're fulfilled to the letter.
One house recently uncovered at Pom
peii appeared to have been undergoing re-
pair at the time it was oyertaken by the
terrible volcano storm of Nov. %, A. D. 70
Painters pots and brushes and workmen' s
tools were scattered about, and spots of
whitewash starred wall and floor. Pots
and kettles had been bundled up in a cor
ner by themselves, but dinner had not been
\ forgotten. A solitary pot stood on the
stove. The oven was filled with loaves of
bread, and a sucking pig was awaiting on
a brown dish its turn to be baked. But the
pig never entered the oven. and the bread
remained in it more that eighteen CEN
turtles. Mons. Florelli's museum at Pom
| peii contains the loaves-twenty-one in
number-rather hard and black, but per-
fectly preserved.

emigrating from South Carolina and going
west in search Of more congenial homes,
Arkansas is receiving the bulk of tho exo-
