Not less remarkable than the epidemic catarrhal fever in Minorca in 1748, or those in Barbados in 1752-3, 1755 and 1757, was the epidemic of 1758 in Scotland[639]. It was first noticed with east winds from the 16th to 20th September, several children having taken fever like a cold. In the last week of September thirty out of sixty boys at the Grammar School of Dalkeith were seized with it in two or three days. In October it became more general, among old and young, and increased till about the 24th, when it began to abate. In Edinburgh not one in six or seven escaped. It was in most parts of Scotland in October—Kirkaldy, St Andrews, Perthshire (where many died of it), Ayrshire, Glasgow, Aberdeenshire, Rossshire (end of October). A gentleman told Dr Whytt that in the Carse of Gowrie, in September, “before this disease was perceived, the horses were observed to be more than usually affected with a cold and a cough.”
The symptoms in Scotland were of the Protean kind of “influenza”: there might be fever with no cold; or a coryzal attack with little or no fever; or some had bleeding at the nose for several days, which might be profuse; or the soreness and pains in the bones might be in all parts of the body, or confined to the cheekbones, teeth and sides of the head. Others had a fever without any distinctive concomitant, but a cough when the fever subsided[640]. One of Whytt’s patients, a lady aged thirty, had been feverish for four days, when a scarlet rash appeared, but did not come fully out; the fall of the pulse and fever coincided with the beginning of a troublesome tickling cough, “so that the cough might be said to have been truly critical.” Those who exposed themselves too soon frequently relapsed. Few died of the disease, except some old people. “In some parts of the country, when the disease was not taken care of in the beginning, as being attended with no alarming symptoms, it assumed the form of a slow fever, which sometimes proved mortal.”
The year after the localised influenza of Scotland there was an epidemic of the same kind in Peru and Bolivia, that year, 1759, being one in which no universal fever or catarrh is reported from any other country. It extended from south to north, along the coast as well as over the high table-lands of Bolivia and the sierra region of Peru, invading, among others, the populous towns of Chuquisaca, Potosi, La Paz, Cuzco and Lima. In five or six days hardly one inhabitant of a place had escaped it, although some had it very slightly. As it was swift in its attack, so it was soon over, lasting about a month in each place. Its symptoms were great dizziness and heaviness of the head (vertigo and gravedo), feebleness of all the senses, deafness, strong pains over all the body, moderate fever, weariness, great prostration, complete loss of appetite, bleeding from the mouth and nostrils (this had been noted in Scotland the year before), and a long convalescence. Dogs shared the disorder, and might have been seen lying stretched out in the streets, unable to stand. It will be observed that the symptoms given do not include catarrh[641].
Before we come to the next general influenza in Britain, that of 1762, there are some facts to be mentioned as to agues and horse-colds in the interval since 1743. In Rutty’s Dublin chronology, agues are entered as prevalent in 1745. In 1750, about the middle or end of December, the most epidemic and universally spreading disease among horses that anyone living remembered made its appearance in Dublin, and in Ulster and Munster almost as soon. It had been in England in November, and was like that which preceded the universal catarrhs of mankind in 1737 and 1743. In 1751, irregular agues were frequent in March, as were also tumours of the face, jaws and throat. Agues also continued to be frequent in April, both in Dublin and in several parts of the country. In December, 1751, and January, 1752, there was another horse-cold, the same as a twelvemonth before. In 1754 the spring agues were frequent in Kilkenny and Carlow, though rare in Dublin. In 1757, “intermittent fevers, which had not appeared since April, 1746,” came in the end of February. In 1760, a great catarrh among horses became general in Dublin in April. Coughs and tumours about the fauces and throat, with a slight fever, often occurred in March; and regular intermittents, tertians or quotidians, were more frequent than for some years past. These, according to Sims, of Tyrone, abated after 1762, so that he had not seen an intermittent since 1764 until the date of his writing, 1773.
The horse-cold of 1760 was observed in London in January. The Annual Register says under date 27 Jan.: “A distemper which rages amongst horses makes great havock in and about town. Near a hundred died in one week.” In a letter a day later (28 Jan.) Horace Walpole writes: “All the horses in town are laid up with sore throats and colds, and are so hoarse you cannot hear them speak.... I have had a nervous fever these six or seven weeks every night, and have taken bark enough to have made a rind for Daphne[642].” This same horse-cold is reported from the Cleveland district of Yorkshire: “In February, [1760] horses were invaded by the most epidemic cold or catarrh that has ever happened in the remembrance of the oldest men living[643].” The same authority for Cleveland says that intermittents were frequent and obstinate in the spring of 1760.
Among these miscellanies of the history may be mentioned an outbreak of “violent pleuritic fever or peripneumene” in the spring of 1747, which was fatal to a comparatively large number in the parish of George Ham, North Devon. Thirteen died of it from the 20th to the 31st March, four in April, four in May, and one in June, “most of them in four or five days after the first seizure.” The same family names recur in the list[644].
The Influenza of 1762.
The universal slight fever or catarrhal fever of 1762 was, in London, much less mortal than those of 1733 and 1743.
