Last year it was my painful duty to record the ravages of pestilence, then indeed hardly terminated, under the pressure of which our general death-rate had arisen to the alarming height of thirty in the thousand. On this present occasion, I have the happier task of laying before you the evidences of a mortality lessened considerably below its habitual average; and I rejoice in congratulating your Hon. Court on the testimony thus borne to the success of your sanitary exertions. For although, without question, some large share of this striking improvement may have depended on circumstances beyond our cognizance or control; although it may in part be but an instance of that tendency to periodical alternations of activity and repose which we recognise in disease, as in other operations of nature; although I should be over-sanguine if I believed, and premature if I stated, that your sanitary measures during the past twelve months had wrought such a change in the City as to ensure a continuance of this year’s comparative healthfulness; yet I may venture without hesitation to assure you, that the labours of the Commission have been fruitful of real and demonstrable advantage to the health of the people; that a sensible diminution has occurred in the physical causes of disease; and that, from various and disinterested sources, I hear grateful mention of improvements which you have effected. In confirmation of this assurance, I may inform your Hon. Court that, in collecting my materials for the present statement, I solicited from the Union-Surgeons of the whole City of London certain particulars of information which they were peculiarly able to furnish; I inquired of them, namely, whether, during the past year, there had prevailed among the poorer classes in their several districts more or less than the ordinary pressure of epidemic, endemic, and infectious disease; and whether, in case of such difference having been observed, they could refer it, either for better or worse, to any changes recently wrought in the physical conditions of their respective neighbourhoods. They have had the kindness to furnish me with the information requested of them; and their replies testify with remarkable uniformity, both to the abatement of disease within their several provinces of practice, and to the considerable dependence of that improved condition of health on sanitary works effected under your auspices. * * * * *
