[We find the following information communicated to the
_Literary Gazette_, apparently by the parties connected with
the improvement.]

Considerable interest has been excited in the market by the
introduction of an improved native raw sugar, which portends very
great advantages to all who are engaged in this so long unprofitable
branch of colonial and commercial intercourse. It is pure raw sugar,
obtained direct from the cane-juice, without any secondary process
of decoloration or solution, and by which all necessity for any
subsequent process of refining is entirely obviated. It is obtained
in perfectly pure, transparent, granular crystals, being entirely free
from any portion of uncrystallisable sugar or colouring matter, and
is prepared by the improved process of effecting the last stages of
concentration in vacuum, and at a temperature insufficient to produce
any changes in its chemical composition; the mode of operation
first proposed by the late Hon. Ed. Charles Howard, and subsequently
introduced, with the most important advantages and complete success,
into the principal sugar-refineries of Great Britain.

By this improved and scientific process of manufacture, the
application of which to the purpose of preparing raw sugar from the
cane-juice has now first been proposed, the most singular advantages
are secured to the planter, in an increased quantity of sugar, the
product of his operation, and in saving from the immense quantity of
deteriorated material, uncrystallisable sugar and molasses, which
were products of the former mode of operation, from the intense and
long-continued degree of heat employed in the processes. The time
and labour of the operation are also greatly decreased; the apparatus
