There are still under the present head, some points to which I am anxious to advert. During the two years that your Act has been in operation, various complaints have been made with respect to nuisances arising in particular trades; and with many of the causes of complaint you have been unable effectually to contend. Soap-makers, tallow-melters, gut-spinners, naphtha-distillers, preparers of patent manure, dealers in soot, exposers of stinking hides, wire-makers, dealers in kitchen-stuff, fish-curers, tripe-boilers, type-founders, gold-refiners, slaughterers, varnish-makers, roasters of coffee and chicory, whalebone-boilers, iron and brass-founders, keepers of cattle-sheds, makers of printing-ink, dealers in camphine, cookers of cats’-meat, and manufacturing chemists, have all, at different times and in various degrees, been complained of. In respect of those of the enumerated trades which deal in the manufacture or sale of organic materials in a putrid or putrescent state, I have already submitted to you my opinion that the City of London, the home of a large and crowded population, is no place for them. With regard to the many other occupations, it would obviously be absurd, in the present state of society, to think of banishing them from the City which their industry has contributed to enrich, and where immemorial custom has given sanction to their continuance, unless you could with certainty affirm of them, that they cause direct and inevitable detriment to their neighbourhood. Every useful purpose, as regards the health of the City, might be fulfilled by the enactment of some moderate restriction. Manifestly, it is opposed to the spirit of your Act of Parliament, that any trader or manufacturer should possess the right of diffusing in the vicinity of his house, to the detriment and disgust of his neighbours, any product (whether in the form of running fluid, or volatile dust, or vapour, or smoke, or odour) which is either disagreeable to the senses or may be hurtful to the health. Many of the instances which I have enumerated fall within this description, and yet remain unaffected by the restrictive sections of your Act.
