Gray thus sums up the great variety of symptoms as related by his numerous correspondents:
Chilliness and shivering, sometimes succeeded by a hot fit, the alternation continuing for some hours; languor and lassitude, sneezing, discharge from the nose and eyes, pain in the head (particularly between or over the eyes), cough, sometimes dry, sometimes accompanied with expectoration, inflammation in one or both eyes, oppression and tightness about the praecordia, difficulty of breathing, pain in the breast or side, pain in the loins, neck, shoulders or limbs, sense of heat or soreness in the throat and trachea, hoarseness, bleeding from the nose, spitting of blood and loss of smell and taste, nausea, flatulence. Also watery blisters about the upper parts of the body, and swellings in the face and other parts, attended with considerable soreness, apparently erysipelatous. In some the catarrhal symptoms were very slight, or entirely wanting, the disorder in those cases being like a common fever.
The committee of the College of Physicians said that “the universal and almost pathognomonic symptom was a distressing pain and sense of constriction in the forehead, temples, and sometimes in the whole face, accompanied with a sense of soreness about the cheek-bones under the muscles,” reminding one of the fierro chuto or “iron cap” of the South American epidemic in 1719. Sometimes no catarrhous affection followed these strange head pains. The languor of body and depression of spirits were thought to be more protracted than in 1762, but the fatalities at the time were fewer than in the earlier epidemic, and there were fewer consumptions following. Sweating, also, was said by some to be less remarkable than in 1762; but Carmichael Smyth said: “The late influenza [1782] might very properly have been named the sweating sickness, as sweating was the natural and spontaneous solution of it[667].” One distinctive thing in the epidemic of 1762 was missed by most in 1782, namely, the peculiar constriction of the breast, with heat and soreness of the trachea, as if excoriated; but Hamilton describes that very thing for 1782 in Bedfordshire[668]. As in other epidemics of the kind, especially those which have been least catarrhal, there were hardly two cases quite the same.
The Epidemic Agues of 1780-85.
Let us now take up the strange history of epidemic agues for two or three years preceding and following the influenza of June, 1782. Sir George Baker begins his account of them thus[669]: “The predominance of certain diseases observable in some years, and the total or partial disappearance of the same in other years, constitute a subject worthy of our contemplation.”
These agues were first noticed in London in the spring and autumn of 1780, but they infested various parts of England a little earlier. In the more inland counties the agues were “often attended with peculiarities extraordinary and alarming. For the cold fit was accompanied by spasm and stiffness of the whole body, the jaws being fixed, the eyes staring and the pulse very small and weak.” When the hot fit came on the spasms abated, and ceased in the sweating stage; but sometimes the spasm was accompanied by delirium, both lasting to the very end of the paroxysm. Even in the intermissions a convulsive twitching of the extremities continued to such a degree that it was not possible to distinguish the motion of the artery at the wrist. “This fever had every kind of variety, and whether at its first accession it were a quotidian, a tertian or a quartan, it was very apt to change from one type to another. Sometimes it returned two days successively, and missed the third day; and sometimes it became continual. I am not informed that any died of this fever whilst it intermitted. It is, however, certain that many country people whose illness had at its beginning put on the appearance of intermission, becoming delirious, sank under it in four or five days.”
Reynolds, another London physician, in a letter to Sir George Baker confirms all that the latter says of these singular epidemic agues: “No two cases resembled each other except in very few circumstances[670]”—the remark commonly made about the influenza itself. If these descriptions of the epidemic ague had not been given by physicians living as late as 1782, and altogether modern in their methods, we might have supposed that they were confusing influenzas with agues, or using the latter term inexactly. “The ague with a hundred names” is the striking phrase of Abraham Holland, in his poem on the plague of 1625. Whitmore, describing the fatal epidemic ague (with an episode of influenza) in 1658-59, does not say that it had a hundred names, but that it assumed a hundred shapes, “which render it such a hocus-pocus to the amazed and perplexed people, they being held after most strange and diverse ways with it.... So prodigious in its alterations that it seems to outvie even Proteus himself[671].”
As farther showing the anomalous character of these epidemic agues, or their difference from the endemic, Baker adds:—
“It is a remarkable fact, and well attested, that in many places, whilst the inhabitants of the high grounds were harassed by this fever, in its worst form, those of the subjacent valleys were not affected by it. The people of Boston and of the neighbouring villages in the midst of the Fens were in general healthy at a time when fever was epidemic in the more elevated situations of Lincolnshire.” Women were nearly exempt, but few male labourers in the fields escaped it.
Baker heard from all parts that the same constitution continued through 1781 and 1782; and that since that time, though it seemingly abated, yet agues had been much more prevalent than usual, and had even been frequent in places where before that period they were uncommon. They were very noticeable in London from 1781 to 1785, not least so during the very severe cold of the winter and spring of 1783-84. We hear of great numbers attacked at Hampstead with common intermittents in February and the following months of 1781, during which time even the measles, in the greater number of cases, “ended in very troublesome intermittents[672]”—just as they were apt to end often in troublesome coughs.
