Another gain for the Leblanc maker would be that he will escape the
cost of removal and disposal of a portion of his refuse or waste.

The plant now erected was calculated for a yield of one hundred tons
carbonate of sodium and about thirty-five tons of sulphur per week,
but it now appears likely that this will be exceeded; while the
carbonic acid plant was supposed to be equal to a yield of 6 tons of
pure gas per day, and is now found capable of doing twice as much.

A few weeks will now bring this new combination process into the
active and crucial test of the markets. Chemists and chemical
engineers have all along taken a keen interest in the ingenious ideas
of Parnell & Simpson. Commercial men are no less interested in the
financial result of the experiment about to be tried at the expense of
a few gentlemen of Liverpool and district. So far as we can learn,
opinions are to some extent divided, though many good judges are very
hopefully inclined. For our own part, speaking with diffidence, as
being a little off our regular track of work, we will only say that we
were favorably impressed with what we saw and heard; and we certainly
wish the venture that full success which its cleverness and its pluck,
as well as its great importance at this crisis, deserve for
it.--_Engineering_.
