Assuming that the cases specially called “spotted” in the London Bills were only a part of all that might have been called by the same name in the wider acceptation of the term (as in Germany), it is a significant fact that there are few of the weekly bills for a long series of years in the 17th and 18th centuries without some of the former. Such a case as that of Mr Samuel Crewe, brother of Lord Crewe, who died of the “spotted fever” on 2 July, 1661, probably means that there were more cases of the same kind in the poorer parts of the town, from which no account of the reigning sicknesses ever came unless it were the number of deaths in the bills. The conditions of endemic typhus were there long before we have authentic accounts, towards the end of the 18th century, of that disease being ever present in the homes of the lower classes. In the time of Sydenham, and even in the time of Huxham two generations after, there was no thought of the unwholesome domestic life graphically described by Willan and others, as a cause of typhus--the overcrowding, the want of ventilation, the foul bedding and the excremental effluvia. If there had been any reason to suppose that the London of the Restoration, or of the time of Queen Anne, or of the first Georges had enjoyed better public health in its crowded liberties and out-parishes than we know it to have done from the time when the authentic accounts of Lettsom and other dispensary physicians begin, then one might err in assuming the perennial existence of typhus fever and in assigning to that cause the bulk of the deaths under the heading of “fevers” in the Parish Clerks’ bills. But the public health was undoubtedly worse in the earlier period. A writer as late as the year 1819, who is calling for that reform of the dwellings of the working classes in London which was soon after carried out, namely the construction of regular streets instead of mazes of courts and alleys, speaks of the “silent mortality” that went on in the latter[20]. It was still more silent in earlier times, when the west end of London knew nothing of what was passing in the east end[21]. In all matters of public health, after the somewhat romantic interest in plague had ceased, the poorer parts of London were for long an unexplored territory. Dr John Hunter, who had been an army physician and was afterwards in practice in Mayfair, began about the year 1780 to visit the homes of the poor in St Giles’s or other parishes near him, and was surprised to find in them a fever not unlike the hospital typhus of his military experience. I quote at this stage only a sentence or two[22].
