Though not intended to GALL forth contro-

rcjoinder signed L. NJ. who takes issue
with the views therein held. II is TO DO
deplorcd that T.. NJ. has hitherto been
denied the opportunity of mastering the
principles Of chemistry.
"Ily introducing already madecrystals in

will admit, not SO however that it is poor

it is rendered uncrystalizable by n poor
sugar boiler, while with good one the

Beet and cane molasses are by no means

Neither have ever heard of lime in n

more nor less, than that saccharne liquids
are not affected by the different forms of
fermentation. The rational of these
changes is as yet imperfectly understood,
the results however being easily apparent :;
of these the actions or acidifying principle,
and the mucous or putrefactive change, in
the former instance requiring simply to
remain undisturbed to bring the same

instance is caused by the presence of gum.

changes shall enlarge upon.
In the DELEGATION of juices, lime answers
two purposes. one to arrest acetous fermen-
tation by combining with the vegetable
ncids present-thus rendering them HARM
less in the form of salts, the other being
to form network of coagulated albumeu
which subsequently rises to the surface, tho
whole process being expedited by neat; any
alkali and some metallic bases will bring
about the same result, but owing to its
cheapness, its slight melassigenic tendency
and indifference to granulation (within
reasonable limitsl lime has been given the
preference and will until the discovery of
cheaper or better agent. Had not the
albuminous principle in E. Ms juices been
coagulated with the assistance of lime, then

Does one grade boiling pay?" is asked
by one friend who also undertakes to
answer the question put, but his premises
are wrong; color does bring something on
sugars sold tho refinery at Manila basis.
