Cattle Market, in premises leased to them by the Corporation of
London, a factory for the purpose of making oleo from fat of oxen
and sheep there slaughtered. A considerable amount of capital
had been invested in the plant of that business. About 90 per cent.
of the fat which enters the factory is treated after a further cleansing
and refrigerating process, and is passed through a mascerating
machine, in which it is chopped up, and then passed on to steam
jacketting kettles, where it is subjected to a heat of 150 degrees.
The fat so rendered, which is termed premier jus, is then passed
into cloths and subjected to pressure, and the more liquid oils pass
away, leaving behind a large residue called stearine. The oil thus
extracted is termed oleo, which forms one of the main constituents
of margarine made by the defendant company. About ten
per cent. of the fat that enters the factory, although pure, is not
used for making oleo, but is dealt with in a different manner. It
is passed into two large digestors into which steam is driven at
high pressure, melting the fat and separating it from the fibrous
tissue. The fat so rendered is mainly sold for culinary purposes.
This process forms a minor or subordinate branch of the defendant
company's business, which is primarily or mainly with oleo
manufacture. The material used in both cases is pure, no
objectional fumes are generated by either melting process, and
the business of the company is carried on without creating a
nuisance. It is therefore not within the mischief aimed at by the
statute, which is directed against a nuisance. But the Section
under which this information is laid, absolutely prohibits the
establishment of certain manufactured materials, which the legislature
views as either necessarily offensive, or likely to be so, and
therefore it is undesirable that they should be established there.
If, therefore, the business of the defendant company comes within
