![2. As regards the Duration, Extent, and Novelty of the Epidemic.—(a.) Of tlic eleven out- breaks here recorded, one commenced in August, two in September, four in October, and four in November. In point of duration, they varied greatly, from one to six months. In several of the districts thus infected the disease lias reappeared after some months had passed without any sign of its presence, hinting that the dijditheria poison may have still survived. The influence of season upon diphtheria prevalence deserves attention. The Registrar General’s quarterly returns show that for the whole of England and Wales diphtheria in its fatal results has a marked, and on the whole very uniform, variation of intensity within each year.

Total 7,501 — 6,047 — 5,613 — 7,829 — 7,508 Average - 750 — 145 605 — 44 561 + 222 783 — 32 751 Table I. shows that in the last 10 years 1870-9 the mortality from diphtheria in the first quarter, sometimes greater, sometimes less than that in the quarter preceding, has alwa3^s exceeded the mortality in the second quarter, and this again in most years (seven out of ten) has exceeded that in the third. The most striking feature in the Table is the great excess which the fourth quarter constantly shows over the third.* From this fact alone, it might be inferred with some probability tliat epidemic diphtheria would be found to originate most frequently in the early part of the fourth quarter. The point is worth investigating, for, if established, it would lend support to the theory that the morbific agent is an organism ivith seasonal development, attain- ing its chief reproductive power in the autumn, the very season when the air is known to be especially charged with fungoid germs. Accordingly, I have collected from the 2nd and later Rejiorts of the Medical Officer of the Privy Council, from Reports by the Board’s Medical Inspectors, and from other sources all the records I could find, in a brief search, of dates of origin of diphtheiia epidemics and have arranged them month by month in the following Table :— Table II.—Monthly Distribution of Diphtheria Outbreaks. 1 ! i ] Reports of Medical Officer of Priv^'Council.
