Yellow fever, which formerly swept not only Southern cities but even New York and Philadelphia, has now been almost entirely warded off.
Such epidemics as that in Memphis a few years since, and the immunity of the city from such visitations since its sanitary condition was changed by Mr.Waring, are a most striking object lesson to the whole country.
Cholera, which again and again swept the country, has ceased to be feared by the public at large.

Typhus fever, once so deadly, is now rarely heard of.

Curious is it to find that some of the diseases which in the olden time swept off myriads on myriads in every country, now cause fewer deaths than some diseases thought of little account, and for the cure of which people therefore rely, to their cost, on quackery instead of medical science.
This development of sanitary science and hygiene in the United States has also been coincident with a marked change in the attitude of the American pulpit as regards the theory of disease.

In this country, as in others, down to a period within living memory, deaths due to want of sanitary precautions were constantly dwelt upon in funeral sermons as "results of national sin," or as "inscrutable Providences." That view has mainly passed away among the clergy of the more enlightened parts of the country, and we now find them, as a rule, active in spreading useful ideas as to the prevention of disease.

The religious press has been especially faithful in this respect, carrying to every household more just ideas of sanitary precautions and hygienic living.
The attitude even of many among the most orthodox rulers in church and state has been changed by facts like these.
