For comparison, I shall place here the aggregates for the last six years to Ratio of liability of meu af the ^he great tendency of the young men to different ages to ^the same diseases in succumb to fevcr and of the old men to die by heat the army of I860 /o. apoplexy, dysentery, and hepatitis.

The death-rates for the young men are also very favourable in both years, although the deaths of young men in the three new regiments which came to India in 1864 contributed consi- derably to the ratio in thc latter year.
