1910-11.] Incidence of Mortality from Pulmonary Tuberculosis. 363 
showing the following percentage reduction at each of these age periods : —

Edinburgh . . 45 - 8 per cent. 47"6 per cent. 33 - 8 per cent. 33‘0 per cent.

The reduction in female mortality has been nearly the same in both cities, 
leaving the female mortality in Dundee much higher than that in Edinburgh. 
Though in the entire population the number of females exceeds that of 
males, individual towns differ in this respect. Among the principal towns 
there are four in each of which the males are in excess, viz. Govan, Coat- 
bridge, Motherwell, and Hamilton (Group 1), and four in each of which the 
females are in excess, viz. Paisley, Kilmarnock, Kirkcaldy, and Perth (Group 
2). The mean population in 1901-7 was 199,910 in Group 1 and 191,060 
in Group 2, so that they are comparable as regards size. The sex constitu- 
tion of the population at census 1901, and the corrected phthisis mortalities 
for 1901-7, were as follows : — 
Group 1. Group 2.

Both groups of towns are industrial, but in Group 1 there is much less 
employment for females (Table XII.). In Group 1 the mortality among 
females is greater than that among males, but is less than among females in 
Group 2, in Scotland as a whole (Table I.) or in its mainland rural districts 
(Table IV.). The mortality among males in Group 1 is less than that in 
Scotland as a whole, or any of its divisions. Plate VII. shows the sex and 
age incidence of the mortality. At the early age periods especially the 
male rate is markedly less than the female. The rates for age periods 15-35 
and 35-55 years are as follows : —

The conditions in the towns of Group 1, while most favourable to males, 
are more favourable to females than those obtaining in the towns of Group 
2 or of Scotland at the same time.
