Mortality in New York. - The unhealthiness of the city of New York is attracting the attention of the legislators at Albany. From the reports published, it appears that New York is one of the most unhealthy cities on the globe, or at least of any of the great capitals of Europe or America. The weekly mortality of Boston appears small in comparison, as some of the wards of New York show nearly as many deaths as this entire city. Week before last 445 deaths occurred in New York, and only 44 in Boston, or one-tenth as many. New York being about four and one-half times larger than Boston, it should have shown (were it equally healthy) only about 200 deaths. In our most sickly seasons, when the deaths in Boston have reached 100 per week, New York has shown 1000 and upwards. Boston had but 17 deaths of Americans one week this month, and its statistics show it to be one of the most healthy places in the world.
