The Russian Technical Society invite
foreign exhibits, especially of such in
ventiOns as have not yet been introduced
into Russia, for the exhibition Of new
machinery, apparatus, and tools of all
classes except agricultural implements,
to be open at St. Petersburg during the
winter, and until the 18th of next
May.
Clouet and Ritter, working separately,
have each discovered that all CONNER
cial grape sugar contains arsenic in
small quantities. Ritter finds that the
amount varies from 0.0025 to 0.1094
grammes per kilogramme. 1t is probable
that the source of the arsenic is the sui
phuric acid employed in the manufac-
ture.
Two remedies have been proposed for
house fungus. Falsky recommends an
alcoholic solution of five grammes sali-
cylic acid per litre. A wash Of this 80
luton will destroy existing fungus and
prevent it's recurrence. Zerener's' pre-
ventive is an application Of waterglass
or infusorial earth, to which per cent.
of salt and 8 per cent Of boric acid have
been added.
Shoe-makers wax has been used with
success in Glasgow to illustrate to the
students of natural philosophy, in a
model, the flow Of glaciers. 1t Is WON
derful how closely the flow of this wax
resembles that of ice. Sir w. Thomson
has also employed this sort of wax to
show the motion Of lighter bodies like
cork, and heavier bodies like bullets,
through viscous substance.
J. E. Reynolds has published sugar
test for determining the purity of water.
Half ltre of water is put into flask,
and then piece of white sugar about
the size of a pea is introduced. The
mouth of the flask is covered with piece
of paper. After the flask is exposed
eight or ten days to the sunlight, its con-
tents will become muddy if the water
held much organic matter.
The Municipality of Paris have made
no arrangements for the lighting of any
portion Of the city with electricity dur.
ing next year, but have agreed to i'm
prove and extend the gas-lighting system,
at an expenditure of about $120,00O. In
all the gas consumed annually in Paris
amounts to $500, 900, 900 cubic feet, and
costs $4,000, 900, or nearly s. year fol
each inhabitant.
Lamarre has stated in communica
ton to the French Academy of Sciences
that at the beginning of violent snow
storm he saw small tufts of light at the
ends of the steel ribs of mis- umbrella
and heard at the same time sort oi
humming sound. When he brought hi
hand near one of the luminous points he
received slight shock, and the lights
then disappeared. This electrical dis
play is rather exceptional.
Poligot has been making some expert
m ents with glucoses, the results of which
he has communicated to the French
Academy of Sciences. When glucose i
subjected to the action of alkalies crys
talllne substance is produced, to which
the name "saccharose" is given. Thi
product has the same composition a!
cane-sugar, but is really distinguished
from it. Saccharose when tasted leave
perceptibly bitter taste in the mouth
and it does not ferment in the presen CT
of yeast. He has found, also, that sa
) ponifcation occurs when glucose is actee
upon by lime.
Speaking of the formation of noun
tains, Professor Favre, of Geneva, ha
said that the three systems which &C
count for the origin of mountains do no
differ greatly from each other. Thos
who admit the system of elevations a
the principal cause would probably admi
the formation Of depressions as sec
ondary cause; while those who give de
preston the first place, would also admi
elevation as secondary factor. Lastly
in the system of lateral crushing there il
general depression of the earth, sinc'
there is diminution in the length O.
the radius of the globe, and yet Their
result elevations OF the ground in tn,
midst of this general depression.
i The British Medical Journal reports
that, at a meeting of the Academic d.
Medicine in Paris, M. Tasteur stated thai
sheep which died of anthrax in a fele
/. in the Department of Eure ct Loire wal
buried in hole dug by the shepherd, al
the district was at considerable dis
tance from a knacker's establishment
From the body of the anthracoid sheer
! germs were produced in such abundance
that the ground teemed with millions O
them in the following year. In coun
ter-experiment, M. Pasteur himself al
lowed some anthracoid blood to fall OF
the ground, and the blood also changet
into germs which could be taken out O.
the earth year afterward.
