[56] It may be brought as a farther proof of a warm climate being unfavourable to every sort of infection, that though the itch is very common in ships and hospitals in Europe, I do not remember ever to have met with it in the West Indies, except in ships newly arrived from England.
[57] This circumstance, in the character of the English, is only of modern date; for we learn from Erasmus, who was in England about two hundred and fifty years ago, that they were then extremely slovenly. The following passage is extracted from a letter he wrote to a physician in York, after his return to Holland:—“Conclavia solâ fere strata sunt argillâ, tum scirpis palustribus, qui subinde sic renovantur ut fundamentum maneat aliquoties annos viginti sub se fovens sputa, vomitus, mictum canum et hominum, projectam cerevisiam et piscium reliquias, aliasque sordes non nominandas.” He adds, that the windows were very ill calculated for ventilation, and imputes to the closeness and filthiness of the houses the frequent and long continued plagues with which England was infested, and particularly the sweating sickness, which, he says, seemed peculiar to this country. He mentions that his own country had been freed from the pestilence by certain changes that the State had made in the houses, in consequence of the advice of some learned man. Erasm. Lib. xxii. Epistol. 13.—It is probable that the greater number of those epidemics, called plagues, were only bad infectious fevers. What would contribute still more to the production of infection was the want of linen, which was hardly in use in those days. The disappearance, or at least the great diminution of such complaints in modern times, particularly in London, has been ascribed to the great increase in the proportion of vegetable food; but it is certainly more owing to the improvement in personal cleanliness, and to the greater spaciousness and neatness of houses. As a farther proof of this, it may be mentioned that in the charity, called the Charterhouse, in London, founded by Henry the Eighth, for the maintenance and education of poor boys, their sustenance is all animal food, as it was at the original institution, yet they are extremely healthy. The same observation applies to Winchester school, which was founded some ages before that.
There are some passages in ancient history in confirmation of the same opinion. Herodotus relates, that the ancient Egyptians were the most healthy of all the nations, except the Libyans, and he imputes this to the invariableness of their weather, and the serenity of their sky. But he mentions in another part of his works, that they were also the most cleanly of all people, not only in their household utensils, but in their persons, and that their clothing was chiefly of linen, which it was one of the principal studies of their life to wash and keep clean—ἑιματα δε λινεα φορεουσι ἀιει νεοπλυτα ὲπιτηδευοντες τουτο μαλισα. Herodot. Euterp. 37.—It is remarkable that he makes no mention of the plague, though he gives a very minute account of the country from his own observation, from whence it may be naturally inferred, that it did not then exist there, though Egypt is now so subject to it, that the plague is supposed by many to be an endemial disease in it. It would appear also from another passage in this historian, that he uses the word λοιμος, which we translate plague in a loose sense to signify any violent acute distemper; for he relates that a great part of the army of Xerxes, in their retreat from Greece, perished by the plague λοιμου and dysentery, in consequence of famine. Herod. Lib. viii. cap. 115.
[58] It is proper also to observe here, that those ships which are built of winter-felled timber are much drier than those built of what is summer felled; and this circumstance should have been mentioned with regard to the Montague, for the cause of her healthiness, notwithstanding her being a new ship, was probably from being built of winter-felled timber. It should, therefore, be strictly enjoined to fell the wood in winter; for those who are employed to do it have an interest in doing it in summer, on account of the value of the bark.
[59] A windsail is a long cylinder of canvass, open at both ends, kept extended with hoops, and long enough to reach from the lowermost parts of the ship through all the hatchways into the open air.
[60] It is not necessary that seamen should have chests, for bags or wallets answer their purpose equally well, and are much more convenient in respect of stowage.
[61] Since the first edition of this work, I have met with a fact in confirmation of this principle, with regard to the cutaneous complaint called the ring-worm. This had prevailed in a private school in the neighbourhood of London, which I visited, but it had to all appearance become extinct; yet it nevertheless affected those boys who were newly sent to the school.
[62] It is mentioned by Thucydides, that while the plague raged at Athens, the people were affected with no other disease; from which it would appear that those persons who would otherwise have been attacked with some particular indisposition, were seized with the plague in place of it. Vide note p. 247.

[64] It is related by the travellers into Turkey, that the Christians save themselves from it, merely by shutting themselves up in their houses, and the inhabitants, who sleep on the open roofs of the houses, do not catch it even from those of the adjacent buildings, though the wall that separates them is of no great heighth.
