The ratio obtained from the hospital books, and those derived from the mortuary registers, agree in displaying the greater liability to attacks of consumption of persons employed within-doors. On comparing Table V. of the former essay, with Table II. of the present, it will be seen that the ratios are, for in-door occupations, 1 to 3-81 and 1 to 1 * 98 respectively ; and for out-door occupations, 1 to 4*13 and 1 to 2*56 respectively. In Table IV. of the first essay, which contrasts in-door and out-door em¬ ployments previous to the elimination of certain exceptional occupations, the ratios were the same for the two classes of employment, while in Table I. of the present essay the ratios are 1 to 2*08 and I to 2*56. The deaths, then, present a stronger contrast between in-door and out¬ door employments than the facts extracted from the hospital books; but the two classes of facts strongly confirm each other. There is also an entire agreement between Tables XIII. and XV. of the former essay and Tables I. and II. of the present, in respect of the distribution of the cases and deaths from consumption according to age. The cases of consumption registered in the hospital books, as occurring under 40 years of age, in men following in-door and out-door employments respectively, were in round numbers 81 and 63 (Table XIII.), or 83 and 62 (Table XV.) ; and in the present essay the numbers are 60 and 54 (Table I.), or 61 and 53 (Table II.). So that here also the two classes of employment occupy the same relative place, and indicate the same com¬ parative liability to consumption, whether the hospital books or the mor¬ tuary registers are used as the mean of comparison. Both agree in repre¬ senting pulmonary consumption to be both more frequent, and of earlier occurrence, in men following in-door emj)loyments, than in those working in the open air. The next inquiry entered into in the first essay, was the influence of different degrees of exertion in ])romoting pulmonary consumption, and
