There was another serious defect in the management of the prison, and that was, the neglect to provide the means for entire ablution, which, in warm climes, becomes an imperative necessity. “Animals perspire, that they may live;” and this function is as necessary to a healthy life as either breathing or digestion: the skin, like the lungs, gives off carbonic acid and absorbs oxygen. But it differs from the lungs in giving off a much larger bulk of the former gas than it absorbs of the latter. The quantity of carbonic acid which escapes varies with circumstances. It is sometimes equal to one thirtieth, and sometimes amounts to only a ninetieth part of that which is thrown off from the lungs, but generally it amounts to 100 grains daily. But exercise and hard labor increase the evolution of carbon from the skin, as it does from the lungs. A large quantity of nitrogen also escapes by the skin.
Hence we may infer the effect upon the prisoners, from the want of ablution, and the means of removing the accumulating filth of their bodies. The functions of the skin, and their influence in the practical feeding of animals, have been carefully studied by the experimentalists, and they have observed that the difference in washed and unwashed animals, during the process of fattening, amounts to one fifth.
Pure air and the enforcement of daily ablutions having been introduced into some of the English schools, the sick rate was reduced two thirds. A general of a beleaguered city in Spain was obliged to put his soldiers on short allowance, and compelled them to bathe daily in order to amuse them, when he found, to his surprise, that they became in better condition than when on full rations.
Chadwick states, in his papers on Economy, that “amongst soldiers of the line who have only hands and face washing provided for, the death-rate is upwards of 17 per 1000.”
When sent into prisons where there is a far lower diet, sometimes exclusively vegetable, and without beer or spirits, but where regular head to foot ablutions and cleanliness of clothes, as well as of persons, are enforced, their health is vastly increased, and the death-rate is reduced to 2½ per 1000.

It appears from the mortuary records of the prison that 13,000 men were registered and buried during the year of its occupation. It also appears from the same hospital lists that 17,873 men received medical treatment, or were known to be sick, and their names entered in the books. Of these, 825 men were exchanged, leaving 17,048 to be accounted for; thus giving a mortality of more than 76 per cent., or 760 men out of every thousand.
It is said, and stated with confidence, that the names of the 4000 soldiers who died in their mud-holes within the pen, and who did not generally receive any medical treatment whatever, were placed upon the hospital register, and their diseases diagnosed after death and removal from the stockade. But of this the writer is not positive, although he has seen tables of statistics of certain periods of the prison, where it is shown that every patient who was treated for disease perished.
