In London from the beginning of registration (1837) until 1846, the deaths set down to dysentery averaged fully a hundred in the year—a statistical fact to which there is nothing corresponding in contemporary writings: Watson said it was hardly ever seen in practice except in the chronic form among sailors and soldiers who had contracted it abroad. During the prevalence of the “Irish fever” of 1846-48, the disease was truly epidemic and a cause of many deaths along with typhus itself, especially in Liverpool and mostly among destitute Irish. In 1846 it was in Milbank Penitentiary[1470]. A most instructive instance of its connexion with the Irish emigration occurred at Penzance in the summer and autumn of 1848.
The brig ‘Sandwich’ sailed from Cork for Boston, U. S., in the end of May, carrying a number of Irish farmers and their families. Having met with rough weather and head winds she put in leaky to Penzance on 7 June, sixteen days out from Cork. The provisions had been bad and there was sickness in the ship, with a very filthy state of things. Three of the women passengers died on shore of dysentery. The ship sailed again on 10 July, two more of the emigrants dying of dysentery before she reached Boston, while two of the crew survived the attack. On 16 July, two cases of the same disease occurred among the lower class in Penzance, and thereafter the epidemic spread widely through most parts of the town and the three adjoining parishes of Madron, Galval and Paul, causing a great mortality, as in the following table:

As many as five hundred cases were under medical treatment in the town. No death occurred there or in the three parishes within the registration district after 10 November, “but very many in the country beyond its limits.” Of the 105 deaths in the table, 46 were of young children, 35 of aged persons, and 24 between the ages of five and sixty years[1471]. There was no resisting the evidence that an infection had been introduced by the weather-bound Irish emigrants; instances were also known of new foci in the country districts having been created by domestics or others suffering from dysentery who had been sent from Penzance to their homes. At the same time the summer had been exceptionally wet, the rainfall having been as follows:
| Inches of rain | ||
| May | 0·777 | |
| June | 3·287 | |
| July | 3·277 | |

A singular epidemic of dysentery occurred between the 14th and 26th September, 1853, among the thirty-six inmates of a row of nine cottages near the village of Hermiston, five miles west of Edinburgh. Seven children were attacked, of whom six died, and six adults, who all recovered. Besides these there were three cases among the four inmates of a cottage about a hundred yards away, and one case in each of two houses in the adjacent village of Hermiston. Christison found that a drain which received the sewage or slops of the hamlet was in a most offensive state, having been choked probably for years, and that the water of a well near it was foetid. These are the conditions that have often caused village epidemics of enteric fever in recent times; but there was no doubt that the disease in this case was dysentery[1472]. Another asylum outbreak of dysentery occurred in 1865 in the Cumberland and Westmoreland Asylum[1473].
Perhaps the last general prevalence of dysentery was during the Asiatic cholera of 1849, when the house-to-house visitations in Leeds and some other towns brought to light a somewhat surprising number of cases mixed with the more ordinary bowel-complaints of the season.
