Mr.. Fryer explained the principle up
on which the apparatus was constructed.
He showed that repeated experiments
had demonstrated the fact that cane Juice
subjected to a rapid cbuIlitIon does not
seusibIy lose its colour or crystalising
power, provided the process is only con-
linued for a very short time, and It's dem
sity not increased beyond 320 Baumc.
When the juice attains this density the
temperature must be kept down to a
poiut below its normal boiling point,
and the duration Of the heat must not be
protractcd. The concretor is an appIi-
cation Of those principles, The juice
having been clarified in the usual way,
Out WIllOuI INC dQuILlOu OI IlIIlts 10 dliON-
ed to flow in a careful, regular stream
over that part of the concretor which is
called the trays. These trays are shall
low, rectangular c%ast-Iron vessels, each
about one and a half yard by two yards,
and are divided on the inner surface by
ribs alternately extending from one side
nearly to the other These trays are
seven in number, and each is connected
with its neighbour in such a manner as
to allow for expansion or contraction.
The whole series are placed in an inclin-
ed position, and subjected to an intense
fire of megass or other fuel, the fame
from which passes underneath their
whole length. The cane juice enters
upon the trays at the upper or furnace
end, and flows backwards and forwards
throughout its entire length, until it
passes to the lowest point, rapidly boil
ing all the time; so that its density on
leaving the trays is raised from about 100
to 2SV. The depth Of the stream does
not exceed half an inch, and the process
of concentration is completed in a very
short time. The products of combustion,
having traversed underneath the trays,
