Thus far the value of
the products obtained by absorption of sulphurous acid has not been
equal to the cost of producing them. Herr C. Landsberg, who is general
manager of the Stolberg Company, has had similar experience, though his
experiments were made to test methods suggested at various times by Dr.
E. Jacob and Dr. Aarland. Both are very ingenious, and were successful
on a small scale, but failed when tried in actual working.--_Engineering

s. d.
Wages--2 men, at 5s. 6d 11 0
Wages--2 boys, at 3s. 6d 7 0
-----
L 0 18 0
Oil, 1 gallon 0 3 6
Waste, 5 lb 0 1 0
--------
Total L 1 2 6
