Several families, who shut up their front and back doors and windows, and avoided going out of their houses except to procure provisions, escaped the disease. I have taken some pains to ascertain, whether any class of tradesmen escaped the fever, or whether there was any species of labour which protected from it. The result of my inquiries is as follows: Three butchers only, out of nearly one hundred who remained in the city, died with the disease. Many of them attended the markets every day. Two painters, who worked at their business during the whole time of the prevalence of the fever, and in exposed situations, escaped it. Out of forty scavengers who were employed in collecting and carrying away the dirt of the streets, only one was affected by the fever and died. Very few grave-diggers, compared with the number who were employed in that business, were infected; and it is well known, that scarcely an instance was heard of persons taking the disease, who were constantly employed in digging cellars. The fact is not new that grave-diggers escape malignant fevers. It is taken notice of by Dr. Clark. It was said by some physicians in the public papers, that the neighbourhood of the grave-yards was more infected than other parts of the city. The reverse of this assertion was true in several cases, owing probably to the miasmata being diluted and weakened by its mixture with the air of the grave-yards: for this air was pure, compared with that which stagnated in the streets. It was said further, that the disease was propagated by the inhabitants assembling on Sundays for public worship; and, as a proof of this assertion, it was reported, that the deaths were more numerous on Sundays than on other days; occasioned by the infection received on one Sunday producing death on the succeeding first day of the week. The register of the deaths shows that this was not the case. I am disposed to believe that fewer people sickened on Sundays, than on any other day of the week; owing to the general rest from labour, which I have before said was one of the exciting causes of the disease. From some facts to be mentioned presently, it will appear probable, that places of public worship, in consequence of their size, as well as of their being shut up during the greatest part of the week, were the freest from miasmata of any houses in the city. It is agreeable to discover in this, as well as in all other cases of public and private duty, that the means of health and moral happiness are in no one instance opposed to each other. The disease, which was at first confined to Water-street, soon spread through the whole city. After the 15th of September, the atmosphere of every street in the city was charged with miasmata; and there were few citizens in apparent good health, who did not exhibit one or more of the following marks of their presence in their bodies. 1. A yellowness in the eyes, and a sallow colour upon their skin.
