Assuming that the observance of the proposed Bye-laws will unavoidably compel a partial reconstruction of the Slaughter-houses in Aldgate, and substantial repairs in the adjacent structures, the washing with quicklime was ordered with a view of providing a suitable and inexpensive coating for the new wood-work of the roofs, &c., for, owing to the constant presence of Sulphuretted Hydrogen in Slaughter-houses, paint is inadmissible from the circumstance that it would speedily be turned black by the action of such gas upon any mineral pigment employed. The limewhiting if used _hot_ would act as a powerful disinfectant and deodoriser, as well as having the effect of greatly reflecting the light in the Slaughter-house, and giving the place a cool and clean appearance. The Metropolitan Board of Works in their 6th Bye-law require that “the occupier shall keep the inner walls of every Slaughter-house always _thoroughly clean_ and in _good order and repair_, and shall cause the internal surface of the _roof_ and _upper portions of the walls_ to be thoroughly washed with quicklime _at least_ once in _every three months_.” The Butchers have probably overlooked this Bye-law in quoting the action of the Metropolitan Board of Works. BYE-LAW XV. That no Slaughter-house or Pound be used for any purpose other than that for which it is licensed, and that no slaughtering be conducted within public view. OBJECTION. _The Butchers maintain that the Pound is not included in the Licence for the Slaughter-house._ REPLY. It is quite true that the word _Pound_ is not used in the Licence for a Slaughter-house, but the Act of Parliament, 1874, distinctly provides that the Bye-laws shall extend to the “_premises_” generally. BYE-LAW XVIII. That in case of any diseased or unsound cattle being brought to a Slaughter-house, Pound, or Lair, the occupier shall forthwith give information thereof to the Medical Officer of Health of the City of London. OBJECTION. _That the retention of the word unsound might involve the Butchers in a charge of Slaughtering Diseased Meat._ REPLY. I should not insist upon the retention of the word “_unsound_” if some guarantee could be exacted that the animal would be slaughtered within a specified time of the occurrence of any accident which might disable it; although it must be remembered that the flesh of a beast suffering pain, or deprived of the full use of all its functions, rapidly deteriorates in quality and nutrient properties. BYE-LAW XXI. That every person occupying a Slaughter-house shall cause the works needful for complying with these Bye-laws to be forthwith executed, and when completed shall not permit any alteration to be made in them without the sanction of the Commissioners of Sewers of the City of London, and that the whole of the works and regulations be carried out to the approval of the Medical Officer of Health. OBJECTION.
