These communications begin with a long letter from the above named Society, consisting of extracts from my Report on Slaughter-houses, dated 1st June, 1875, with observations upon the same, given point by point in parallel columns. These remarks are really little more than a “_réchauffé_” of those already set forth in the voluminous epistle of the Society, dated 10th April, 1876, addressed to the Local Government Board, and I fail to recognise any more important differences than the following, viz., some very ungracious and totally irrelevant reflections upon the conduct of the District Sanitary Inspectors, for the forbearance shown by those officers in allowing the greatest latitude as to the defects and nuisances observed in the butchers’ premises to continue with as little interference as possible until the new _régime_ could be established; also a statement that your Engineer is at variance with myself in the recommendations given to your Committee, the truth being that they were prepared by that officer in conjunction with your Solicitor and myself. Further, the Society inform the Local Government Board, that disease germs have never been known to rise to a height of six feet, and that therefore the side walls separating adjoining Slaughter-houses need not be built as high as the Bye-laws require! This is a fair sample of the recklessness with which the “Butchers’ Trade Society’s” last production has been framed, and pays a poor compliment to the discrimination of the Local Government Board, who may, if they think fit, educate the Society to the fact that disease germs have been known to travel many thousands of miles, carrying with them cholera and kindred diseases from the far East to the distant West;--a corresponding degree of ignorance characterises the dicta of the butchers upon the physical laws which govern the movements of currents of air, and which for convenience is called ventilation. Again, the Society claim an exceptional state of salubrity and freedom from disease for butchers as a class--a proposition which I have already shown you is untenable. Further information may be obtained upon this subject from a Report written by Dr. Buchanan, one of the Medical Inspectors of the Local Government Board, upon the connection between scarlet fever and cow sheds, in a district under his charge. Lastly, the Society ask, whether in my judgment the butchers would be less unhealthy in the Slaughter-houses as arranged according to my plan, and I answer broadly and unhesitatingly, Yes.
