“The present fever, with a variation in some of its symptoms, has now subsisted twelve years [or since 1718] not in England only, but all over Europe [Manningham says it was peculiarly English]. Few or no physicians suspected the reigning and popular disease to be a fever. Vapours, a nervous disease, and such general appellations it had from sundry physicians. Others, who discovered the fever, knew it was the low or slow fever, first mentioned by Hippocrates.... The last were represented as ignorant for calling the distemper a fever, and affixing to it the name ‘low’ or ‘slow,’ a slow fever being, in their adversaries’ opinion, altogether unheard of among physicians and never recorded in their books. Nothing was more monstrous than calling this distemper a fever, or confining persons afflicted with it to their bed, and dieting them with broth, or other liquid food of good nourishment, and what is easily concocted.... ‘You are not hot, you are not dry; you are in good temper; and therefore you have no fever’ was the common language of the town.... They might have seen physicians practising for a destroying distemper, and yet, after seven years, they confess themselves ignorant of its very name.” At length, he continues, Blackmore admitted the ambiguity of diagnosis, while Mead, Freind and others, recognized that there was really such a thing as a slow, nervous fever, by no means free from danger to life. It is probably to this insidious fever that Strother refers: “Thus, having gone on for six or seven days in a train of indolence, they have been surprized on the seventh day, and have died on the eighth lethargick or delirious, whereas, if they had taken due care, the fever would have run its course in fifteen days or more.” It was the remissions, or intermissions, he explains, that often misled patients, by which he seems to mean the clear intervals between relapses. “Others, wearied out with relapses, have hoped their recovery would as certainly ensue as it had hitherto, and have deferred asking advice until it was too late.” These relapses, he thought, were brought on by venturing too soon into the air: “it is too well known that the fever has been cured, and patients have soon, after they have ventured into the air, relapsed and have again run the same circle of ill symptoms, if not worse than before.” Bark failed conspicuously in these “remittents:” “it is therefore incumbent on me to examine into the reason of this _new phenomenon_. I call it _new_,” he explains, because bark had hitherto succeeded. “Perhaps we may find reason to lay some blame on the air for the frequent relapses.... Periodical comas have of late been common; so soon as the fit was over, the drowsiness abated till the fit returned.”
