The Influenza of 1712.
There were so many fevers from 1693 to the end of the century that it is not easy to distinguish epidemic agues or catarrhs among them. If we follow the continental writers, it is not until 1709 and 1712 that there is any concurrence of testimony for such widespread maladies. Evelyn, however, says that in the remarkably dry and fine months of February and March, 1705, “agues and smallpox prevail much in every place” (21st February). The very general coughs and catarrhs of 1709 seem to have been really caused by the severity of the memorable hard winter, the frost having begun in October, 1708 and lasted until March, 1709. The evidences of a truly epidemic infectious catarrh or influenza all over Europe in 1709 are scanty and ambiguous. It is probably to this “universal cold” that Molyneux refers under the year 1708[607]; but English writers have not otherwise mentioned an epidemic in 1709.
The next, in 1712, was a “new ague” of the kind without catarrhal symptoms, like that of 1688. One German writer called it the “Galanterie-Krankheit,” another the “Mode-Krankheit,” and it was about the same time that the French name “la grippe” came into use. These names all mean “the disease a la mode” or the reigning fashion[608]; they remind one of the earlier “trousse galante” and “coqueluche” (a kind of bonnet), and of the “grande gorre” of 1494. It appears to have made little or no impression on the mortality, and would hardly have been noticed but for its wide prevalence. In England it was the subject of a brief essay by Dr John Turner under the title of “Febris Britannica Anni 1712[609]”—a certain epidemic fever, of the milder kind, fatal to none, but prevalent far and wide and leaving very few families untouched. It was marked by aching and heaviness of the head, burning or lancinating pains in the back, pains in the joints like those of rheumatism, loss of appetite, vomiting, pains of the stomach and intestines. The venom though not sharp, acted quickly. Turner ascribed it to malign vapours from the interior of the earth (malignos terrae matris halitus). Its season in England, as in Germany, was probably the summer or autumn. Turner begins his discourse with a reference to the plague in the East of Europe, which, he says, had been kept out of England by quarantine, to the murrain which was then raging in Italy (and appeared in England in 1714), and to fevers of a bad type which had traversed all France during the past spring, invading noble houses and even the royal palace. Having begun his discourse thus, he ends it by remarking that the slight British fever did not, in his opinion, forebode a plague to follow. It may have been a recurrence of this epidemic next year that Mead speaks of under the name of the “Dunkirk rant” (supposed to have been brought over from Dunkirk by returning troops after the Peace of Utrecht) in September, 1713; it was, he says, a mild fever, which began with pains in the head and went off easily in large sweats after a day’s confinement[610]. The weekly bills of mortality in London are no help to us to fix the date of the one or more slight fevers or influenzas about 1712-13. The great fever-years of the period were 1710 and 1714; but the fever was typhus, probably mixed with relapsing fever, according to the evidence in another chapter. Even compared with the universal fever or influenza of 1688, that of 1712 must have been unimportant; for the former sent up the London mortality considerably, whereas there is no characteristic rise to be found in any month of 1712 or 1713.
Either to this period, or to the undoubted aguish years 1727-28, belongs a curious statement as to “burning agues, fevers never before heard of to be universal and mortal,” in Scotland, the same having been a “sad stroke and great distress upon many families and persons.” The authority is Patrick Walker, who traces these hitherto unheard of troubles to the Union of the Crowns (1707)[611].
On other and perhaps better authority, it does appear that Scotland before that period was reputed to be remarkably free from agues; and it is probable that the universal and mortal burning agues some time between 1707 and 1728, had come in one of those strange epidemic visitations, just as the agues of 1780-84 did. It would be erroneous to conclude from such references to ague that Scotland had ever been a malarious country. Robert Boyle refers in two places to the rarity of agues in Scotland in the time of Charles II.; the Duke of York, he says[612], on his return out of Scotland, 1680, mentioned that agues were very unfrequent in that country, “which yet that year were very rife over almost all England”—to wit, the epidemic of 1678-80. Again, agues, especially quartans, are rare in many parts of Scotland, “insomuch that a learned physician answered me that in divers years practice he met not with above three or four[613].” However, Sir Robert Sibbald, while he admits the rarity of quartans, does allege that quotidians, tertians and the anomalous forms occurred, that agues might be epidemic in the spring, with different symptoms from year to year, and that certain malignant fevers, not called agues, were wont to rage in the autumn[614].
