Extract of a private letter from New York:

JUNE 1ST, 1847– “Ship fever is now very prevalent here. It is, properly speaking, a most malignant kind of yellow fever. In almost every vessel that arrives several persons are afflicted with it, in consequence of which all the hospitals are full. The Board of Health are fitting up temporary places for the reception of patients. From the numbers that have been attacked, it is feared, that the fever will spread through the City as soon as the warm weather sets in.

At present it is confined to the neighbourhood of emigrant boarding houses. Dr. Van Buren, who has been stationed at the quarantine ground, has died of it, and several of the doctors that have been attending the Marine hospitals are ill with it. 567 have died on the passages from Great Britain to New York, since the 1st of January.
