In Table II. the statistics for Scotland and for England and Wales are 
more fully compared. The rates for Scotland are corrected to sex and age 
constitution of census 1901. In the first three decades the rates for England 
and Wales are corrected to the sex and age constitution of that country in 
1891-1900. The ratio of the corrected rates to that occurring in decade 
1861-70 in Scotland and in England and Wales respectively are also 
given. It shows that in decade 1861-70 the mortality from pulmonary tuber- 
culosis in Scotland was higher than that in England and Wales, and that 
since that period the decrease in the mortality among both sexes in 
Scotland has been only 49 per cent., while it has been 55 per cent, in 
England and Wales. The decrease according to sex has been very 
different in the two countries. While in both the decrease among males 
has been practically the same, indeed has been rather greater in Scotland, 
the decrease in mortality among females has been only 50 per cent, in 
Scotland compared to 63 per cent, in England and Wales. At the present 
time the greater mortality from tuberculosis of the lungs among the entire 
population of Scotland as compared with that of England and Wales is 
due to the greater mortality among females, and this latter is due to the 
fact that the decrease in the rate of mortality among females has been much 
less than in England and Wales.
