I take conveniently from Murchison the following succinct account of the Scots relapsing fever of 1842-44[387]:

“The next epidemic of fever in 1843 differed from those that preceded it, inasmuch as it did not originate in or implicate Ireland, but was mainly confined to Scotland. There was no increase of fever in the Irish hospitals during this year, whereas the number of admissions into the Glasgow Infirmary rose from 1,194 to 3,467; in the Edinburgh Infirmary from 842 to 2,080; and in the Aberdeen Infirmary from 282 to 1,280. These numbers, too, are far from representing the true extent of the epidemic, for thousands of sick were sent from the hospital doors. The fever was almost exclusively relapsing fever; typhus was comparatively rare. The first cases were observed on the east coast of Fife, in 1841-2 (by H. Goodsir), and not in the crowded localities of large towns. In Dundee, where the proportion of typhus cases was comparatively great, the fever appeared early in the summer of 1842, and raged to a considerable extent during the whole of the autumn, before it showed itself elsewhere. In Glasgow the first cases occurred in September, 1842; but the fever was not generally prevalent until December, from which month the cases rapidly increased until October, 1843, when the epidemic began to decline. The number of cases in Glasgow was estimated at 33,000, or 11½ per cent. of the entire population. In Edinburgh relapsing fever was first observed in February, 1843. It rapidly spread until October, after which it gradually abated, until, by the following April, it had well nigh disappeared. In the month of October, 1843, the number of fever cases admitted into the Edinburgh Infirmary amounted to 638, and during several months, from thirty to fifty cases were daily refused admission. The total number of cases in Edinburgh was calculated by Alison at 9,000. In Aberdeen the epidemic commenced about the same time, and followed the same course as in Edinburgh. At Leith, curiously enough, it did not appear until September, 1843; it then spread rapidly for two months, after which it declined, and by the end of February, 1844, it had almost ceased; but during this brief period it attacked 1,800 persons, or one in every fourteen of the population. The disease was general over Scotland, and was not restricted to the large towns; it prevailed in Greenock, Paisley, Musselburgh, Tranent, Penicuick, Haddington, Dunbar, the Isle of Skye, etc. Although the epidemic was mostly confined to Scotland, the same fever was observed in some of the large towns of England. The number of admissions into the London Fever Hospital rose from 252 in the preceding year to 1,385 in 1843: and the annual report for 1843 makes it evident that a large proportion of these cases were relapsing fever. The rate of mortality of the epidemic was small, not exceeding from two-and-a-half to four per cent. Although this was the same fever as prevailed in 1817-19, even local bleeding was rarely resorted to, and many of the cases were thought to demand stimulants. All accounts agree in stating that the epidemic supervened upon a period of great distress among the Scottish poor, and that it was restricted throughout to the poorest and most wretched of the population.”

This epidemic, which was the subject of an altogether unusual amount of writing in Edinburgh[388], partly on the supposition that relapsing fever was a “new disease,” proved once for all that one had not to go to Ireland for the engendering or making of a famine-fever. The demonstration came just in time; for the epidemic was hardly over in Scotland, when the series of great potato-famines in Ireland began in 1845, soon to be followed by the disastrous epidemics of dysentery, relapsing fever and typhus from 1846 to 1848. Indeed, so near was the Scots epidemic to the Irish, that in the North of Ireland the first of the relapsing fever, in 1846, was called “the Scotch Fever,” on the supposition that it had reached them from its recent focus in the West of Scotland[389]. The Irish and original part of the great epidemic of 1846-48 has been fully described in another chapter; much of the mortality was due to dysentery, and the most prevalent fever was relapsing fever, with a very low rate of fatality among the poorer classes. But in Ireland itself there was also much typhus, very mortal to the richer classes who came in contact with the starving multitudes.

The “Irish Fever” of 1847 in England and Scotland.

The contagion that reached England and Scotland from the scene of famine in Ireland was more apt to produce typhus than relapsing fever. That the Irish contagion was the principal source of the great epidemics in England and Scotland in 1847-48, seems to be proved by every fact in their progress, direction and other circumstances. But it is not so clear that England and Scotland would not have had an unusual amount of typhus in the same years even if the Irish had been kept out by an ideally strict quarantine. What touched Ireland most, touched Scotland and England in a measure. The seasons were bad in all parts of the kingdom; many were out of work in the manufacturing towns; but as soon as the price of provisions fell in 1848, the epidemic in England came to a sudden end.

The epidemic of fever in England in 1847 was almost wholly typhus; in Scotland, it was to some extent relapsing fever, but there also it was mainly typhus. It was more severe, while it lasted, than the epidemic of 1837 and following years; but it was of shorter duration, ceasing almost abruptly in 1848. The rise of the epidemic of 1847 in London is shown by the following quarterly returns of the deaths from fever:

1st Quarter 2nd Quarter 3rd Quarter 4th Quarter
442 568 895 1279

In the last quarter of 1846, the deaths from fever in London had been 619. In all England, the last quarter of 1846 was also most unhealthy, its deaths from all causes being 53,055 (only 43,850 in the first quarter of the year). The summer of 1846 had been remarkable for heat and drought, and the end of the year was, according to precedent, an unwholesome time. It was just the season for enteric fever, as in the still more memorable circumstances of 1826. There is evidence from various parts of England and Scotland that much of the fever of the end of 1846 was enteric; and it was doubtless the unusual prevalence of that disease, and of other maladies that are favoured, like it, by extreme fluctuations of the ground-water, that explains the very high mortality of the last quarter of 1846[390]. But it is equally certain that it was typhus which raised the fever deaths in London in the last quarter of 1847 to 1,279, and the deaths from all causes in all England to the enormous total of 57,925. In the whole of the year 1847, typhus alone claimed 30,320 deaths in England and Wales, the total in 1848 falling to 21,406. Lancashire and Cheshire had the largest share of this epidemic, and Liverpool the largest share in Lancashire. In that Registration Division (the North-western) the deaths from typhus in 1847 were 9,076, and in 1848 they were 3,380. Next in order (excluding London and suburbs) came the West Midland Division, and next to that Yorkshire. At Liverpool, and in other places of the north-west of England, the fever was very clearly connected with the enormous Irish immigration, and was in great part among the Irish. There were floating lazarettos on the Mersey, filled with fever and dysentery, workhouses overflowing, and sheds hastily built to hold each 300 patients. The following returns from the several sub-divisions of Liverpool for the months of July, August and September, 1847, show the proportions of dysentery and fever, as well as the mortality from diarrhoea, which last was mostly an affair of the infants and young children[391]:
