The Influenza of 1788.

According to Barker, of Coleshill, who kept systematic notes of the epidemic maladies from year to year, there were several recurrences of the influenza of 1782[682]. But there is only one of these seasons, the summer of 1788, that other English writers have singled out as a time of influenza. It was undoubtedly of a very mild type, producing hardly any effect upon the bills of mortality; but it attracted the notice of several. Dr Simmons, the editor of the London Medical Journal, became the recorder of it, collecting reports from various parts, as others had done in 1782. He himself treated 160 cases at the Westminster General Dispensary, and 65 more elsewhere. It was most prevalent in London from the second to the fourth week of July, but the mortalities for those weeks show no abrupt rise. It was at Chatham, Dover, Plymouth and Bath about the same time, at Manchester in the beginning of August, in Cornwall in the middle of August, and at Montrose about the end of August, or perhaps most certainly in October. On 5 August, a physician at York wrote: “We have not had the slightest appearance of a catarrh in our city or neighbourhood during the year.” The epidemic was undoubtedly a partial one in Britain, and so slight as to have made little impression where it did occur. It is said to have been very general at Warsaw in April or May, at Vienna in April (20,000 cases before the 20th), at Munich in June, at Paris in the end of August and still continuing on the 24th October, at Geneva on the 10th October. Its most constant symptom in England was pain in the fore-part of the head, with vertigo; next most constant was a pain at the pit of the stomach and along the breast-bone; cough was wanting in perhaps a third of the cases and was always slight, diarrhoea was somewhat general, running from the eyes exceptional, sore-throat in perhaps one-sixth of the cases[683]. At Plymouth where it was seen earliest and clearest among the regiment of artillery and in the guardships, the symptoms were pain in the head and limbs, soreness of the throat, pain in the breast, a feeling of coldness all over the skin, and these followed by cough, a great discharge from the nose and eyes, and slight nausea. It was much less noticeable among the townspeople than among the troops and sailors[684]. It occurred chiefly among soldiers or sailors also at Dover and Chatham. At Bath it was marked by chills, headache, swelling of the throat, difficult swallowing, quick pulse, hot, dry skin (but not pungent as in malignant fever), ending in a sweat; no delirium, but broken sleep or vigil; the eyes scarcely affected, cough in some, but not vehement; in some, sublingual swellings which suppurated[685]. At Manchester it looked as if it had been brought in by travellers who had acquired it in London[686].

At Portsmouth a singular thing happened two or three months after the epidemic had passed. The frigate ‘Rose’ arrived on 4 November from Newfoundland; within a short time all the dogs on board were seized with cough and catarrh, and soon after the whole ship’s company were affected in the same way[687]. Simmons says of the epidemic of 1788 in general: “During the progress of the influenza, a complaint which was evidently an inflammatory affection of the mucous membrane of the fauces, etc. was frequently observed among horses and other cattle, and was generally as violent among them as it was mild among their rational neighbours”—many dying after four or six days.

The very slight and partial influenza of July and August, 1788, happened at a time when there was much fever of a more serious kind in the country. The history of the latter belongs to another chapter; but there was in Cornwall, in the same season as the influenza, an epidemic fever which might in former times have been described as a part, and the most fatal part, of the “new disease,” and may be taken in this context rather than in the chapter on typhus. The same physician, Dr William May, of Truro, gave an account of the influenza first[688] and of the other fever afterwards[689].

The latter began at Truro in the end of April, 1788, and was also at St Ives and other small towns in various parts of the county. A malignant fever had for near two years before been exceedingly rife among the poor (owing to distress from loss of pilchard fishing), and had carried off a great number of them; but this was something new. Yet it was “truly a fever of the typhus type,” one of its symptoms being constant wakefulness. It passed through whole families, affecting all ages and constitutions. It ended on the 17th day, whereas the influenza (says May in his other paper) ended with a sweat on the fourth or fifth day. In one small neighbourhood this epidemic fever affected chiefly the aged, who were blooded owing to dyspnoea: out of ten or eleven so affected, not one recovered, an experience that reminded May of what Willis said of the village elders being swept off by the “new fever” of 1658. Surgeons at St Austel, East Looe and Falmouth are cited as having seen much of the same fever. In like manner the Manchester chronicler of the influenza of 1788 says: “Fevers of different kinds, but chiefly of the type now distinguished by the appellation of typhus, were exceedingly prevalent after the epidemic catarrh had in great measure ceased to be general; but from which, by tracing the symptoms, the fever might usually be found to have originated[690].”

For a good many years after the period last dealt with, nothing is heard in Britain either of epidemic agues or of influenza[691]. Writing in 1800, Willan said that intermittents had not, to his knowledge, been epidemic in London at any time within twenty years. He explains this by “the practice of draining, and the improved modes of cultivating land in Essex, Kent, and some other adjoining counties, from which either agues were formerly imported, or the effluvia causing them were conveyed by particular winds”—the latter being the doctrine of Lancisi for the country round Rome. But he forgets that their appearance nearly twenty years before was a strange phenomenon to the practitioners of that generation, and that Sydenham, whom he cites to prove agues in London in former times, had also remarked their absence, except in occasional cases, for as long a period as thirteen years. Of such occasional agues acquired in London, Willan and Bateman had each one or two examples in the autumn of 1794, and the spring of 1805.

As in the case of epidemic agues, so also in the case of influenzas, there was immunity in Britain for a good many years after 1788; and, as the slight epidemic catarrh of 1788 was something less than universal, the clear interval may almost be reckoned from the summer of 1782, a space of over twenty years. Willan’s monthly reports of the weather and diseases in London from March, 1796, to December, 1800, twice mention epidemic catarrhs,—in February and March, 1797, and in February, 1800, the latter chiefly among children. But to neither of them will he concede the name of “influenza,” as the complaint was merely epidemical from a particular state of the atmosphere, and not propagated by contagion, nor quite general.

The symptoms, however, were headache, sometimes attended with vertigo, a thin acrid discharge from the nostrils, slight inflammation of the throat, a sense of constriction in the chest, with a frequent dry cough, pains in the limbs, a white tongue, a quick and small pulse, with a sensation of languor and general debility. These symptoms, fairly complete for influenza of the correct type, lasted about eight days and ended in a gentle sweat or in a diarrhoea. Coughs had been remarkably severe and obstinate; they were frequently attended with painful stitches and spitting of blood[692].
