Sydenham says that a continued fever, the symptoms of which so far as he gives them suggest typhus, was mixed with the masked intermittent, (or the convulsive fever of children, as in Willis’s account), in every one of the years 1661-4; and that statement raises a question which may be dealt with here once for all. Fever in the London bills is a steady item from year to year, seldom falling below a thousand deaths and in the year 1741, during a general epidemic of typhus, rising to 7500. The fevers were a composite group, as we have seen, and shall see more clearly. But the bulk of them perennially appears to have been typhus fever. Where the name of “spotted fever” is given there can be little doubt. Every year the bills have a small number of deaths from “spotted fever,” and the number of them always rises in the weekly bills in proportion to the increase of “fever” in general, sometimes reaching twenty in the week when the other fevers reach a hundred. It would be a mistake to suppose that only the fevers called spotted were typhus, the other and larger part being something else. The more reasonable supposition is that the name of spotted was given by the searchers in cases where the spots, or vibices or petechiae of typhus were especially notable. If a score, or a dozen or half-a-dozen deaths in a week are set down to spotted fever, it probably means that a large part of the remaining hundred, or seventy, or fifty cases of “fever” not called spotted were really of the same kind, namely typhus. In the plague itself, the “tokens,” which were of the same haemorrhagic nature as the larger or more defined spots of typhus, were exceedingly variable[19]. One of the synonyms of typhus (the common name in Germany) is spotted typhus; but the spots were of at least two kinds, a dusky mottling of the skin and more definite spots, sometimes large, sometimes like fleabites.
