    in hastening the period of its attack* - This point was illustrated by Tables VL and XVII. of that essay. The following table shows, for occupations requiring different degrees of exertion, the per centage proportion dying of pulmonary consumption at each period of life, and under 30 and 40 years of age, the ratio of deaths from that disease, and the number of facts upon which the table is founded:— Table III.

The ratios obtained from the hospital books were, for the first three classes of employment, 1 to 3*08, 1 to 4*44, and 1 to 5 *06; those deduced from the mortuary registers are, 1 to 1*76, 1 to 2*20, and 1 to 2*10. In both cases the sedentary class of occupations holds the same place, and presents the highest ratio ; but employments requiring great exertion hold the second instead of the third place in the mortuary registers. The difference, however, which causes this change of place is so slight as scarcely to deserve attention, and may probably be explained by the small number of deaths entered under this head. The age at which pulmonary consumption proves fatal in the three classes of in-door employment corresponds wuth the age of attack, as obtained from the hospital books. The numbers under 30 and 40 years of age respectively follow the same order as in Table XVII. of the first essay. In the class of employments with varied exercise, the proportion of deaths from consumption under 40 years of age does not bear the same relation to the other classes as does the proportion of attacks of con¬ sumption. The proportion of deaths under 40 ranks next to that ob¬ tained for the sedentary class of occupations, while the proportion of attacks under 40 is higher than that which prevails among persons following sedentary occupations. Though the position of these two classes is different, the two together occupy the same place, in respect of the other two classes of in-door occupation. It will be observed, that the proportion of deaths under 30 dops not preserve the same relative position as the proportion under 40 years of age.
