That which recently excited the Close
attention of the observers of the oomei
Pons-Brooks was the remarkable chang
es in the intensity of the brightness it
presented from time to time.
Whatever may be true of harmless
luxuries in the way of drink, the Lancet
maintains that health, happiness, and
work find stimulus enough in the IN
sophisticated we'll of nature-in pure
water.
Direct electric lighting of one of the
trains of the District Railway between
Kensington and Putney is stated to be
very successful. The light is not only
superior to that obtained from oil or gas,
but is reported to cost only two-thirds
that of the latter.
Good shellac varnish is made as fol-
lows: Take of very pale shellac )
pounds, mastic ounce, and alcohol or
pints, and dissolve in the cold to pre-
vent the evaporation of the alcohol, stir
ring the mixture meanwhile. This is a
good vaInish for furniture, and it Is much
employed in France by cabinet-makers.
A cinerary urn has been discovered on
the farm of Guilty hill, Longside, Aber-
deenshire, Scotland. The shape of the
urn is globular, Is inches in diameter
and IL riches in depth. 1t was formed
of a brownish sort Of clay. The bones
which filled the receptacle crumbled in
to dust on being touched.
If the express ed belief of some Cornish
miners regarding the probable develop
ment of the tin mine of CajalcO, in the
| Temiscal Range, California, turns out to
be verified later on, it will prove of vast
importance. They are of opinion that
| the vein struck will increase in richness
as it increases in depth. Lately the
mine assayed 1871 per cent. from the ore,
of purity of 0.98.
Herr c. Schneider, of Dresden, has in
vented dry galvanic battery. 1t con-
sists of two cylinders, the larger one of
copper and the inner or smaller one of
amalgamated zinc. Both cylinders are
open at each end, and the space between
| them is filled in with a mixture of plas-
ter of Paris and saturated solution OF
| chloride of zinc containing per cent.
of chloride of sodium.
Iron sulphate is good manure for
certain kinds of crops. A plot OF land to
which the sulphate had been applied by
Mr.. A. B. Griffiths of the Chemical Soci-
ETY., London yielded 56 bushels of beans.
A plot similar In other respects which
hau not been MANFRED gave only 80
bushels. The ash of the plants from
first plot contained more iron and phos-
phoric acid than those from the second
plot.
Several methods of treating vines af-
fected by phylloxera have been describ-
ed by NJ. F. Hennequy at late meeting
of the Academy of Sciences, Paris. The
process of NJ. Menden consists in satur-
ating the sap with solution of phoniC
acid, but it seems that the parasite con
tinued to flourish in spite of the doctor
ing of the sap. NJ. Aman-Vilie propes
es to inject into the earth a mixture o.
, vapors of sulphur and sulphuric acid
This has been tried, but on far too limit
ed scale to speak in any definite terms
of its efficacy. The vines co not seem tC
have been very perceptibly benefited by
the treatment of the earth, because the
vapors of sulphuric acid do not penetrate
to sufficient depth into the ground, and
besides, it is found that they evapOratt
too rapidly.
