There is a progressive decline under “convulsions” and a progressive increase under diarrhoea. The year 1846 was undoubtedly marked by an unusual amount of choleraic disease; but the high level of the diarrhoeal deaths was maintained from that year, so that it is probable that some radical change had been made in the mode of entry. The nearly equal proportion of deaths from diarrhoea and from convulsions in London has continued since that time to the present, the former falling mostly in the third quarter of the year, the latter not unequally on all the quarters.
In all England and Wales during the first five and a half years of registration the deaths from diarrhoea were few compared with the numbers relative to population in later periods:

There is a break in the annual tabulations of the returns for four years from 1843 to 1846; when they are resumed in 1847, the diarrhoeal death-rate per million living is found to have apparently risen to an enormous height, at which it remained somewhat steady for a whole generation.

From year to year the mortality has fluctuated enormously, as in the following list, the rise or fall depending for the most part on the kind of summer: e.g. that of 1893 was hot, and had an excessive mortality from infantile diarrhoea.
