    That is to say, the difference between the actual incidence on ages in the aggregate Causation of of years of greater or less prevalence was— by ' In those under 1 year, as 100 to 82 = difference 18. Dr. Ballard. „ 1 year and under 5, „ 62 = ,, 38. ,, under 5 years, „ 64 = „ 36. „ over 5 years, „ 50 = 50. Looking, then, at the actual incidence on age, it is obvious that, on the whole, in Islington greater or less general prevalence affected most those over five years, next those between one and five years, and least of all those under one year. In confirmation of this estimate of incidence of those under one year I have in the above table added columns to show that when these diarrhoea deaths are calculated upon the births similar results are obtained. Comparing the Eedditch series with the Islington series we find, as respects the Redditch years of greater or less general prevalence, the actual incidence of age to be as observations, follows :— Per 1,000 Estimated Population. Years. Under 1 Year. 1 Year and under 5. Under 5 Years. 5 Years and upwards.

We see, therefore, that in Redditch the difference of actual incidence in years of greater or less prevalence was observed most in the infants under one year, and nearly to the same extent, in those over five years, and least of all in those between one and five years. But both in Islington and in Redditch, in the aggregate, the difference in actual incidence in high or low years of general prevalence respectively was much greater in the case of those over five years of age than in the case of those under five years. (e.) Seasonal Variation within the same Year in the Amount of Diarrhoeal Sickness. Seasonal variation. The malady is not only present among the population every year, but in all seasons and at all times of every year ; hut not in all seasons and times alike. Oases of so-called diarrhoea * are never absent from medical practice throughout Annual the year. It is further notorious that they vary in number at different periods of fncj^aTe^^nd the same year. Taking all ages together and all years together, there is found to he a decline. gradual increase of prevalence from about the beginning of the year to somewhere beyond the middle of the year, and then a gradual diminution oj prevalence up to the end of the year. Table II. (pp. 48 and 49) shows these fact's and precisely what the character of the variation was in Islington. In Table II., I omit the figures of the extraordinary (cholera) year 1866 from calculation, and add, in place of them, those of the ordinary year 1869. See foot note on page 10. D 4
