Mr. Hill states, that he has no doubt the results, which will be apparent from the examination of the several tables which are placed in juxta-position, would be corroborated by similar returns obtained from other well-regulated prisons in Scotland. The returns from the prisons in England up to the year 1834–5 (which do not, however, give the days of sickness, but only the number of prisoners attacked with sickness during the period for which the return was made) further corroborate these results. Even in the Milbank Penitentiary, the situation of which is insalubrious, the average annual amount of sickness to the prisoners who are confined two years and a half is only about eight days to each person, which, for the average ages, is little above the standard obtained from the experience of the East India Company’s labourers. The sickness amongst the metropolitan police is about 10½ days per annum for each of the force, 2¾ per cent. being constantly on the sick-list. The sickness in the army is on the average 14½ days each soldier. Mr. Finlaison informs me he can venture to state, that were any benefit society to use scales of premiums founded on the prison experience, they would inevitably be insolvent in less than three years. M. Villermé has shown the diminution of mortality that has taken place in the prisons of France, chiefly from stricter attention to cleanliness, ventilation, and diet, to be equally striking. At Lyons, from 1800 to 1806, the annual mortality in the prisons was 1 in 19; from 1806 to 1812, it was 1 in 31; from 1812 to 1819, it was 1 in 34; and from 1820 to 1826, 1 in 43: a similar amelioration has also been remarked in the prisons of Rouen, and some other large towns in that kingdom. The following is a summary return of the diseases of the duration of each, amongst the population of the wynds, examined by Mr. Tait:—
