In many marshy, fever plagued dis
triets Of Europe and Africa the expert
ment of planting in large numbers the
Eaoaiypt,s, or feyer-tree, has been tried
for some years, and late report shows
that the result is the almost total ham
isment Of feyeIs frum these regions.
During a series Of photometrie OBJ
ssryations, Prof. w. II. Pickering has
found that the total brilliancy Of the
sun isequal 10 about $50 900 full moons.
To better Illustrate this relation. it
may be stated that II the whole Of the
visible heavens were turned irto one
full moon 1t would give rather less than
~one-fouTth Of the light of the sun.

chimpanzee has been trained to feed

In Scotland considerable interest Is
taken In n new method Of tanning hides,
effected not by means Of tannin in any
form, but Of chrome. The q process
is said TO be cheaper and more expedi-
tious than the old. and TO produce leath-
er stronger. more durable and especially
less peryions To moisture. About three
hundred chrome-tanned hides have
lately been exhibited in Glasgow, come
Of them made into betting, harness,
boots, etc.
"Female torpedoes" are an attraction
at Belgian fairs. In the center OF a
booth is a pit which the spectators en-
circle, and in this pit a woman. attired
rs n gymnast, walks about on n plat
form. Now and then she touches n
spectator ON the hand or cheek, and the
latter receives n smart electric shock,
but the woman feels nothing. She is
evidently highly charged with electrici-
ty by means Of an induction coil, aud
the platform on which she stands Is one
pole Of the coil. The electrified nymph
is n great success, and her singing ca
~rcsscs elicit roars Of laughter from the
visitors.
Perhaps the most remarkable opera.
ton hitherto recorded In tho history Of
submarine t%clegraphy is that which has
just attended the work OF the Eastern
Telegraph company's steamship Chit
ern. In 1870 n cable was laid from the
coast Of Portugal, and recently perse-
vcring efforts have been made TO crap
pie and raise this old cable at n point
where II lay in 1900 fathoms of water.
The general idea Is that n cable must
be rotten after 30 long al immersion
and cannot be raised, but this cable has
been successfully brought tothe surface,
and was found to be ms good and rs
strong as when laid ten years ago. Ic

i An experiment made In the harbor oil
Kiel proves that heavy weights may be
readily lifted from the bottom of the
sea by means Of n balloon. The balloon
is made OF canvas and metal plates,
with an attached cistern containing
carbonic acid gas compressed TO n liz.
uid state. When made fast to a sunken
object, the communication between
the cistern and the balloon is opened;
imitation takes place. the sunken vessel
or whatever else IL may be. Is lifted,
and a be lowed away ut pleasure. In
the experiment Mt Kiel. nm apchor-ston
weighing fifteen tons was thus lifted
from n depth of thirty.two feet. The
lifting power of n balloon ten feet in
diameter Is said to be more than one
hundred tons
