So far as his clinical cases are concerned, the late appearance of miliary vesicles, lasting a few days, is sufficiently explained by the powerful drenches administered; and it can hardly be doubted that much of what was called miliary fever was of that factitious kind. But even in Hamilton’s essay we find indications of a real miliary type of fever; thus he mentions a class of cases which look to be the same as those described by Johnstone, Rutty, Sims and others forty years after—cases with wakefulness, depression, tremblings of the tongue and hands, convulsive movements and delirium. He mentions also a complication of this with sore-throat in 1704, which destroyed many.
As to the association of miliary eruption with the low putrid fever so characteristic of the sixth decade of the 18th century, it is asserted by too many and in too various circumstances for any doubt as to its reality. There is nothing to show that the alexipharmac treatment was the one always used; and it is not certain that some in Ireland and elsewhere who had miliary eruption received any medical treatment at all. Again, miliary vesicles, not always with perspiration, were commonly found in the relapsing fever of Irish emigrants in London during the great famine of Ireland in 1846-47, by which time the powerful drenches of the alexipharmac treatment had been long disused[226]. The controversy as to the reality of miliary fever was one of the kind usual in medicine: certain physicians, of whom Hamilton in 1710 was an obvious instance, took up an untenable position; they were answered according to the weakness of their argument; and that has been held in later times to be an answer to all who alleged the existence of a type of fever marked by miliary eruptions. There can be no question as to a low, “putrid” kind of fever in which miliary eruptions were usual; but offensive sweats were perhaps more usual, whence the name of putrid in a literal sense, different from the theoretical sense of Willis; more constant also were the starting of tendons, the tremors and shakings, together with very varied hysteric symptoms, from which the fevers received the name of nervous. Dr John Fordyce in his ‘History of a Miliary Fever’ (1758) really describes under that name the symptoms of the low, nervous, putrid fever, often attended with miliary vesicles, which had been the common type in England in the years immediately preceding, and was a common type for some time after, although less is heard of the miliary eruptions in the later history[227].
About the last quarter of the 18th century medical writers were inclined to drop the names of nervous and putrid as distinctive of certain fevers. Pringle, in his edition of 1775, says he had been careful to avoid the terms nervous, bilious, putrid and malignant, which conveyed either no clear idea or a false one. Armstrong, another army physician, writing in 1773, says: “Nervous, putrid, bilious, petechial or miliary, they are all of the malignant family; and in this great town [London] these are almost the only fevers that have for many years prevailed, and do so still, to the great destruction of mankind. For inflammatory fevers ... have for many years been remarkably rare[228].” Dr John Moore becomes sarcastic over the variety of names given to continued fever, some such generic name as Cullen’s “typhus,” then newly introduced, being what he desired[229].
Haygarth, writing of the Chester fevers in 1772, said that the miliary fever had been “supposed” endemic there for more than thirty years past, but he thought it probable that the eruption had generally, or always, been fabricated “by close, warm rooms, too many bed-cloaths, hot medicines and diet.” He had seen only one case in the epidemic that year, and he believed its rarity at that time was due to the treatment by fresh air and by “such regimen and medicines as are cooling and check putrefaction[230].” We shall see later that Percival, for Manchester, contents himself with saying that miliary fevers, which were formerly very frequent in that town and neighbourhood, now [1772] rarely occur[231]. In Scotland as late as 1782 the type was still nervous or low, and hardly ever inflammatory[232].

It is singular to observe that in the five successive years in this period with lowest fever-deaths and deaths from all causes, the years 1757-61 England was at war on the Continent. A similar low fever-mortality corresponded with the wars under Marlborough and Wellington.
The era of agricultural prosperity in England, which had its only considerable interruptions in the years 1727-29 and 1740-42, may be said to have met with a more serious check from the bad harvest of 1756. There was a recurrence of agrarian troubles in 1764-67, partly through actual scarcity caused by the extreme drought of 1764, partly through the pulling down of cottages and the discouragement of country villages, which Goldsmith has pathetically described in his poem of the time. Short says that the country in 1765 was in general very healthy but for children’s diseases. “In some parts the putrid fever roamed about from place to place in the highest degree of putrefaction, so as several dead bodies were obliged to be buried the same day as they died.” The price of provisions was excessive, meal riots broke out, and the export of corn was stopped, Parliament having been summoned for the occasion in November, 1766[233]. In 1769, at the time of the formation of Chatham’s ministry, the same train of incidents recurred,—bread-riots, flour-mills wrecked, corn and bread seized by the populace and sold at low prices, collisions with the military, the gaols full of prisoners[234]. The long period of cheapness, having lasted half a century, was coming to an end. Moralists and economists had much to say as to the meaning of the national distress which began to be felt in the sixties. Want of industry, want of frugality, want of sobriety, want of principle, said one, had brought trouble on the working class. “The tumults that have lately arisen in many counties of England are no other than the murmurs of the people, which have been heard for some years, bursting forth at last into riot and confusion.” The English, it seems, had returned to their old medieval taste for the best food they could get; they would not give up the finest bread, although the Irish lived on potatoes, and the French on turnips and cabbage: “The ploughman, the shepherd, the hedger and ditcher, all eat as white bread as is commonly made in London, which occasions a greater consumption of wheat.” Women must have tea and snuff, though children go naked and starved. Another writes: “The poorest people will have the finest or none.” The enclosures had made a want of tillage. “What must become of our poor, destitute of work for want of tillage?” The country had for the most part been sickly, labourers scarce, and the farmers not able to get their usual quantity threshed out. The profligacy of the poor, profane swearing, etc., are remarked upon[235].
In the last thirty years of the 18th century the accounts of fever in England became more detailed as to its circumstances, and more numerically precise. I shall accordingly bring together all that I can find relevant to fever in London, Liverpool, Newcastle and Chester, and thereafter in those towns, such as Manchester, Leeds, and others in the North, which were specially touched in their public health by the movement known as the Industrial Revolution.
