DR.. Mond went on to say that he had
hesitated to extend the new method in
connection with the ammonia-soda pro-
cess as rapidly as he woulds0therwise
have done. because of the possibilities in

trolysis.
1.-THE electrolysis method for the manu-
facture of chloride OF potash. bleaching
powder, and caustic soda for the decom-
position of salt, instead of the employ
ment Of bi-sulphuric acid, has been in
use for some time in Germany and also
to a small extent In the United States. 1t
Is claimed, that by the application of
electricity. the chemicals can be produce
ed more cheaply than by the old method.
The electrolytical methods do certainly
produce more direct results, but local ex-
perts say that ii is yet too soon to def
niteiy decide whether they are more eco
nomical than the old method. as there
are 80 many considerations which time
alone can solve. such as the wear and
tear OF machinery and the cost of replace
ment, which are expected to be serious
items Of expenditure Where electricity
can be produced by water power. as in
Norway and at Niagara and other
places In the United States, the new pro-
cess will have a better chance Of sue
cess than in England, where 1t must be
produced at great cost in the consump-
ton of coal. The various electrolytical
processes in use in this ne:ghborhaad are:

prospectus was issued inviting the SUBJ
scription of capital This was not allowed
to go further. as the Castner-KeIlner
Company obtained an injunction restrain
ing the Rhondin Company on the ground
that their process was an infringement OF
the Castner-Kellner patents.
Speaking generally. there has been a
steady decline in prices at Liverpool, dat
ing from 1898. The following figures show
the downward movement: Sulphate of
ammonia-In 1893, sss.13 per ton: in 1897.
$4o.H. Caustic soda-In 1885, Si622 per ton:
in 1897. $a5.SS. Soda ash GebIanc)-In 1893,
s2z-50 per ton: in 1897. $2l.sS. Ch,orate of
potash-In 1898. 16 cents per pound: In 1897.
7.6 cents. Bleaching powder-In 1888, $i1.35
per ton; in 1897. $3o40 Muriate Of ammo
nia-In 1893 $LSs per cwt-: In 1897. $4.e5.
Carbonate of soda-Prices have slightly
fiuctuated: in 1895, the price was s19iG per
ton: in 1897. s2os7. Sal ammoniac-The price
has been very steady from 1893 to 1897, IL
being about ssd per cwt. for first quality
