neither sickness nor death during the voyage. The other vessels, consisting of two from Limerick, one from Sligo, three from Dublin, two from Liverpool, and one from Greenock, with 2,386 passengers, had together 198 deaths and 286 sick on their passage.
But even ships which leave the same port simultaneously Difference in health of vessels leaving same port at same timeshow a very remarkable difference in the respective health of their passengers. This must be ascribed to the better condition of the same ship and of the passengers in the one case, and to the previous poverty and insufficient nourishment in the other. Thus, the ship Lucy Thompson, after a passage of twenty-nine days arrived The Lucy Thompsonat New York, from Liverpool, on the llth of September, 1853, with a loss of forty out of 835 passengers by cholera. The William Stetson The William Stetsonarrived on the same day, after a passage of thirty-one days, with 355 passengers, having lost none on the passage. The Great Western arrived on the day previous, September 10, The Great Westernafter a passage of thirty-one days, 832 passengers, no death having occurred on board. On the 19th of September, 1853, the Isaac Webb arrived The Isaac Webbat New York, from Liverpool, with 773 passengers, after a passage of twenty-nine days, seventy-seven having died of cholera. On the next day, the Roscius arrived The Rosciusfrom the same port, with 495 passengers, after a passage of thirty-five days, six days longer than that of the Isaac Webb, and yet with out a single death. On the l5th of October, 1853, the Montezunma arrived The Montezunmaat New York, from Liverpool, in forty-one days, with 404 passengers, and a loss of two; while the Marmion arrived The Marmionon the same day, after a passage of twenty-five days, with 295 passengers, and a loss of thirty-six by cholera, The Washington, arrived The Washingtonat New York on the 23d of October, 1853, after a passage of forty-one days, with 952 passengers, and a loss of eighty-one; while the Guy Mannering arrived The Guy Manneringon the 25th of the same month, after a passage of thirty-seven days, with 781 passengers, and without loss.
These examples might be multiplied almost at pleasure, showing that vessels which left the same port almost at the same time, and reached the same point of destination about the same time, and consequently would be supposed to have been in the same latitudes and subject to the same winds at the same time, suffered in very different degrees. The cases presented show conclusively
