Curiosities and Discoveries in the World c
Progress.
M. Outer has proved experimental.
that the magnetism of Hat steel mag
nets whose surfaces are their poles doe
not disappear when they are removed
from the magnetic field.
Perscite, a saccharine substance 81
closely analogous to mannire that un
til recently it has been COMPOUNDED
with it, occurs, says NM. A. Munts
and V. Marcano, in the fruit of Lauru:
persea.
| Canarinc, a new tinctorial substance
discovered by Muller and Markovni'
koff, is not soluble in water, ether,
spirit or benzine, but only in bases ac-
cording to the strength of which ii
gives different colors from pale yellow
to red.
About 400 steel guns, of the six-inch
class and OF an eclectic type, have
been finished for the rearmament of
the smaller vessels of the British Navy.
Large guns, constructed on the same
general principle, are now in course of
completion for the larger ironclads.
Discussing the occurrence of alkalies
in beryl Mr.. Samuel L. Penfeld main
tains, in the american Journal Of
Science, that the results of numerous
investigations show that alkalies are
always present, undoubtedly replacing
the beryllium, and that water is also
present and can not be disintegrated
in the formula.
A new electric battery has been
made by Tomassi and Radiguet. Both
of the electrodes consist of plates of
coke, the one surrounded by paste of
lead peroxide, and the other covered
on its horizontal upper surface with
fragments of platinized coke. The
two are separated by means of parch-
ment paper. The exciting fluid is a
saturated solution of sodium chloride.
In the preparation of farm yard ma
nure M. p. P. Deherain states that
straw is oxidized in contact with the |
air only under the influence of "fgur |
ed" ferment. There may be distin-
guished in dung q neutral fermenta-
ton producing carbonite acid and for
meme, and an acid fermentation in
which are produced butyric acid, ny
drogen and formene.
When purified wood charcoal is
saturated with gascuous
chlorine, and then treated with n.y.
drogen gas, hydrochloric acid is form
ed with fall of temperature. Berthe
lot and Guntz explain this anomaly by
jhe consideration that the absorption
If heat results not from the chemical
lcti N, properly speaking, but from
he multaneous evaporation of the
chlorine condensed upon the char
,oal.
Prof, G. F. Wright, treating on the
Niagara river and the Glacial Period,
nfers that the river itself has worn
he whole of the gorge from Queens
on to the Fall, with perhaps some
title assistance from preglacial ero-
ion above the whirlpool. The rate of
rosion, calculated at about three feet
year. would make the time requisite
or the work so performed not over
0, 1000 or II, 900 years.
G.. Schmitt and A. Coblenzi, the
-merican Chemical Journal says,
ave made a careful investigation of ,
ne unfermentble substances found in ,
commercial starch sugars, and have j
lcceeded in isolating a definite COM ,
Ound, to which they give the name of ,
gallisin." Physiological experiments
q the lower animals and on human !
,ings demonstrate clearly thatgallisin I
is, neither directly nor indirectly,
~ bad effect on the health.
To prevent the cracking of the glass T
hes that are connected with steam r
pliers to show the height of the water t
thin it is recommended that two h
ass tubes be used, one within the d
her. The air that is confined be- II
Teen the two serves as a protection
the inner tube against outside cold o
ID the outer one against the high n
mperature of the inner one. Both n
bes are packed in the same brass o
uplings. But the device is hardly 7,

Among the conclusions advanced by ii
Baland in the second memior on je
ur are the following: The proper d
n of moisture contained in the vari- es
S products of grinding is sensibly NJ
, same. There is Il constant rela- OF
n between the hygrometric state of dt
, air and the degree of moisture of n
flour. Flours generally contain fir
IN to 3 per cent. more moisture in
nter than in summer. The mean of ii,
'isture in the hcurs of commerce is eS
per cent. ST
4. Anne Girard regards the grain to
wheat as consisting of three parts, an
shell (Which forms 14.36 per cent?, tn
germ GAS per cent?, and the w
inaceous layer y per cent?. In ch
ecent paper on the chemical COM sill
'ition and the ailmentary value of co
various parts of such a grain he wi
lsiders that the introduction of the pc
II and the germ into the flour is pl
y of an insignificant utility, and is ca
ended with serious Inconvenience. Gel
