The report on the local epidemics concludes by earnestly recommending to the government—“That sanitary measures be adopted by means of which the constitution of the people may be renewed, and their longevity increased. If this recommendation be fulfilled, we may then hope to see the condition of some of the departments ameliorated, in which now the population is so degenerated that the men seem to diminish in size each time they are measured for the conscriptions.” Evidence on the mismanagement of expenditure in respect to supplies of food, on mismanagement also in respect to clothing and fuel by the labouring classes, might be added to complete the view of the principal causes of disease prevalent amongst them, but these do not come within the immediate scope of the present inquiry, which has been directed chiefly to the investigation of the evils affecting their sanitary condition, that come within the recognized provinces of legislation or local administration. The information on the means for the prevention of epidemic disease arising in the common lodging-houses maintained for the accommodation of trampers and vagrants, might also have been considered in connexion with the subject of the effects of overcrowding and filth which they strongly exemplify; but it appeared most convenient to consider them apart, from the exposition of what may be termed the indigenous evils that afflict the settled inhabitants of the labouring class. I would now submit for consideration, 1st, the total expense of the present state of things, so far as a proximate view of it can be obtained, on the health, strength, and life of the lower classes of the population. 2d, a proximate view of the pecuniary expense of such partial remedies as are at present applied or applicable to alleviate the consequences of these preventable diseases.
