5th.—That the Company have been using for too long a time the
Oxide of Iron supplied to them for the purification of the gas, and thus
the purifiers have not had the opportunity of acting as effectively as
they might have done, if they had been charged with fresher
Oxide of Iron.
6th.—That as regards the purification of the gas from Ammonia,
the processes in use at the works are very defective, for there was only
a partial washing of the gas with water, in such a manner as to fail in
the proper removal of this impurity.
In conclusion, I have the honor to state as to the result of these
inquiries, that I am of opinion the complaints in the memorial as to the
impurity of the gas supplied to the Parish of Saint Leonard, Shoreditch,
by the Independent Gas Light and Coke Company, are well founded,
and that the impurity is referrible to certain persistent defects in the
works and not to any unavoidable cause or accident.
I have, &c.,
