| B,R-IRoN FROM PHosPHURETTED CAST IEoN.-The
following are the essential features of the process
| for eliminating phosphorus from cast-ron, devised
| by Prof Scheerer! of Freiberg; and which, 1t Is
claimed yields superior bariron from phosphuretted
| cast-ron, at practically, no increase oil cost.
! Chloride of calcium and common salt fused
together in about equal proportions, are intimately
mixed with the molten iron in the pudding furnace,
| either by adding gradually in two pound water
tight paper packages or placing the whole quantity
| required upon the bed Of the pudding furnace at
first and in either case very thoroughly working 1t
with the iron. The pudding process rs generally so
much shortened that the consequent dmnuton OF
the waste of iron almost offsets the cost OF the mate
rial added The quantity of the mixed chloTides re-
quired il about three times that of the phosphorus
present in the cast-iron. The presence of other
chlOrides rs of manganese, iron and magnesium,
intereFes with the process, and renders large eX
cess of chloride Of calcium necessary.
VALUE OF THE STEAM JACKET FOR ENGINEs.-An
animated discussion has lately taken place. before
the Scientific and Mechanical Society of Manchester
to the value of the steam jacket around the oyn
der of steam engine in aiding in the working OF the
engine by preventngthe too rapid loss OF heat. Mr..
Hildebrand mentions, among its advantages, that
il slightly increases the power of the engine. and in
sures greater immunity from break downs caused
| by an accumulation of water in the cylinder; but
that on the other hand, it entails positive waste
of fuel greater labor in attendance and an increased
outlay of capital TO the amount OF % per cent For
these reasons he concludes that the question az to
case of hOtair jackets will form an exception, pro-
vided the hot or other hot gas would otherwise
be wasted But here come in the objections-that
the extent of experimenting is not under as good con-
troll as with steam, and carried too far lmpalIs the
durability of the cylinder, by depnying IT OF the
piston.
INFLUENCE OF CLIMATE AND MANUREs UPON
PIANTs-In the Journal of the horticultural So
ciety of London is given a second report by NJ. L.
Masters upon extended experiments made at their
Gardens to determine the effects of various fer
tilizers mineral manures, ammonia salts, and nj
trates upon different species of plants. Aside from
the results possessing an economic value, certain
conclusions are drawn Of scientific nature, in
relation to the inducement of specific changes. No
absolute change in habit was in any instance OBJ
servable, the effect of the manures being simply to
enhance the vgOr of growth, or the reverse and
more decidedly in the leaves, STEM &C. than IN the
flowers fruit Nothing favored the inference that,
by the agency of any manure or yiclssitude OF cl-
mate any change that would be deemed of specific
value could be artfciay induced. On the contrary,
it would appear. as all other evidence yet obtained
shows, that specific" character ~ not Influenced by
external conditions hut is an innate quality trans
mitted by hereditary descent
PATENT WAGON-LUBRICANTs.-A resin-lme soap,
prepared by stirring 80 pounds of dry-slaked lime
into 100 pounds of rosn oil, and heating, with con-
tnued stirring until pasty mass, free from Jumps,
is formed, which finally from the stirTer like
sirup is principal ingredient of different forms of
patent axle grease. Some of these are prepared as
follows Blue by boiling 500 pounds of crude IOsin
oil one hour with two pounds of dry -slaked lime,
allowing it to COOL drawing off the oil from the sed
ment and stirring into it, while still warm 10 to 10
pounds of the above soap, until blue mass of the
consistency of butter is obtained. Yellow, by
adding to this six per cent of an extract of tur-
meric prepared by boiling one part of tur-

pounds of lampblack, rubbed up with rosin oil, to
100 pounds Of the blue mass. Patent palm-Ol lubri
