renders it a little more friable ; for this reason I use alcohol for 
the first operation, and claying for the second. The alcoholised 
loaves retain the smell of it for some time, which, however, goes 
off by placing them for a short time in a stove, or even on sim- 
ple exposure to the open air. It is necessary to employ alcohol 
concentrated to 36 degrees; when it is weaker it dissolves a 
portion of sugar. It is not entirely lost, for by distillation it 
may be freed from the melasses, and employ ed again as before. 
Another method of refining has been proposed, which does not 
appear to me to possess the advantages of the new one just de- 
scribed, or even of the old one: it consists in dissolving 100 
parts of raw sugar, and treating it with ten per cent. of charcoal 
and ten whites of eggs. When the loaf is in the form, they 
cause one and a half per cent. of white syrup to run through. 
Account of the Expenses and Product of a Manufactory of 
Sugar from Beet. 
The process I have described appears to me to be the most 
eertain, ceconomical, and simple of any that have come within 
my knowledge: and if the price of the sugar produced from it 
is greater than the sugar of commerce brought from the new 
world, it is still a new fact in science, and an object of curiosity 
to society. We shall now give an exact statement of expenses 
and receipts, in order that every one may be able to judge of the 
importance of this new branch of industry. 
The expenses are comprised in the price of the beet, the ma- 
nual labour for the extraction of the sugar, the interest of the 
sums spent in forming the establishment, the maintenance of the 
machines, the purchase of fuel, animal charcoal, and other less 
considerable articles. Beet-root is usually sold at ten franes 
per thousand weight ; at this price the cultivator has hitherto 
-met with a reasonable profit, especially when it is raised in suit- 
able soil. By supposing it to be raised in land of a middling 
quality, but yet good enough to produce corn, we may calculate 
that an acre of ground will produce a crop of beet at the fol- 
lowing expense :
