The essay of Strother also has a reference to “spotted fever” in its title, although the text throws very little light upon it[106]. But, for the rest, the “constitution” of 1727-29 is more than usually perplexing. There was an influenza at the end of 1729, which can be separated from the rest easily enough by the help of the London weekly bills of mortality; and it is probable, unless Arbuthnot, Huxham and Rutty have erred in their dates, that one or more epidemics of catarrhal fever had occurred before that, in the years 1727 and 1728. The greatest difficulty is with a certain “little fever,” or “hysteric fever,” or “febricula,” which gave rise to some writing and a good deal of talk. Strother does not specially treat of it, at least under that name, although he says that “many, especially women, have been subject to fits of vapours, cold sweats, apprehensions, and unaccountable fears of death; every small disappointment dejected them, tremblings and weakness attended them,” etc. (p. 116); and again, “never was a season when apoplexies, palsies and other obstructions of the nerves did prevail so much as they do at present, and have done for some time past” (p. 102); while he had frequently seen hysterical and hypochondriacal symptoms, dejection of spirits and the like remaining behind the fever (p. 109). For some years before this, much had been heard in London of the vapours, the “hypo,” the spleen, and the like, an essay by Dr Mandeville, better known by his ‘Fable of the Bees,’ having first made these maladies fashionable in the year 1711[107]. In due time it began to be noticed that symptoms which many physicians made light of as a “fit of vapours” were really the beginning of a fever. Dr Blackmore, in an essay on the Plague written in 1721, admitted the ambiguity: “For several days a malignant fever has so near a resemblance to one that is only hysterick, that many physicians and standers by, I am apt to believe, mistake the first for the last, and look upon a great and dangerous disease to be only the spleen, or a fit of the vapors, to the great hazard of the patient[108].” In 1730, Dr William Cockburn, in a polemic against the physicians whom he styles “the academical cabal” (because they objected to his secret electuary for dysentery), professes to give a history of the mistakes of the faculty in London over this “little fever,” or “hysteric fever,” which often became dangerous[109]:
