The Influenza of 1675.

The first that we hear of the universal cold of 1675 is an entry which Evelyn makes in his diary under 15 October: “I got an extreme cold, such as was afterwards so epidemical as not only to afflict us in this island, but was rife over all Europe, like a plague. It was after an exceeding dry summer and autumn.” It was not until November that the epidemic cold made an impression upon the death-rate in London; the deaths mounted up from 275 in the week ending 2 November, to 420 and 625 in the two weeks following, and thereafter gradually declined to an ordinary level. Part of the excess, but by no means the greater part of it, was set down under fevers, as the following section from the weekly bills of the year will show:

1675

Week Ending		Fever	Smallpox	Griping in the Guts	All causes
Nov.	2	42	9	29	275
	9	60	12	42	420
	16	130	13	43	625
	23	99	2	28	413
	30	61	6	29	349
Dec.	7	54	7	25	308
	14	43	5	12	266

This shows the characteristic rise and fall of an epidemic catarrh both in the article of fever deaths and in the column of deaths from all causes. The other excessive articles besides fever in the two worst weeks are also characteristic of influenza mortality:

	Week ending 9 Nov.	Week ending 16 Nov.
Consumption	68	99
Aged	40	67
Tissick	10	35

Sydenham’s account bears out the figures[586]. At the end of October, he says, the mild, warm weather turned to cold, while catarrhs and coughs became more frequent than at any time within his memory. They lasted until the end of November, when they ceased suddenly. Afterwards he gives a special chapter to the “Epidemic Coughs of the year 1675, with Pleurisies and Pneumonias supervening.” The epidemic spared, he says, hardly anyone of whatever age or temperament; it went through whole families at once. A fever which he calls febris comatosa had been raging far and wide since the beginning of July, with which in the autumn dysenteric and diarrhoeal disorders were mingled (it was an exceedingly dry season). This constitution held the mastery all the autumn, affecting now the head, now the bowels, until the end of October, when catarrhs and coughs became universal and continued for a month. Sydenham’s view of the sequence of events was his usual one, namely, that one constitution, by change of season, passed by transition into another. Whatever the constitution of “comatose” fevers may have been, which prevailed “far and near,” it has left no trace upon the bills of mortality in London, which are remarkably low until the beginning of November. But as soon as the epidemic of coughs begins, the weekly deaths mount up in an unmistakeable manner, so that for two or three weeks in November, the mortality is nearly double that of the weeks preceding or following.

The “severe cold and violent cough,” of 1675, says Thoresby of Leeds[587], who was then a boy, “too young or unobservant to make such remarks as might be of use,” was known in the north of England “profanely” by the name of the “jolly rant.” Thoresby well remembered that it affected all manner of persons, and that so universally that it was impossible, owing to the coughing, to hear distinctly an entire sentence of a sermon. He gives December as the month of it in Leeds, and says that it affected York, Hull, and Halifax, as well as the counties of Westmoreland, Durham, and Northumberland. In Scotland also we find a trace of a strange epidemic sickness. It was the time of the persecution of the Covenanters, whose preachers moved hither and thither among the farm-houses. One of them, John Blackadder, was at the Cow-hill in the parish of Livingstown in August, 1675. He came in one evening from the fields very melancholy, and in reply to questions, he said he was afraid of a very dangerous infectious mist to go through the land that night. He desired the family to close doors and windows, and keep them closed as long as they might, and to take notice where the mist stood thickest and longest, for there they would see the effects saddest. “And it remained longest upon that town called the Craigs, being within their sight, and only a few families; and within four months thereafter, thirty corpses went out of that place[588].” The prophecy was fulfilled within four months, which would bring us to the date of the influenza, although the mortality for a small place is somewhat excessive.
