Report of a Localized Outbreak of Cholera Due Apparently to Contaminated Water and Milk

on board the ship Ardenclutha. is interesting as showing how localised outbreaks in widely scattered parts of a town may break out simultaneously, and, though seeming to have no connection, may have a common origin which is neither 4 ue to any climatic conditiou, nor to a peculiar epidemic state of the atmosphere, but to taking 111,? * system a something which has been polluted by cholera excreta. eating from Dr. Birch that several cases of cholera had been admitted into the General ospi a of Calcutta from one of the ships moored in the river, it occurred to me that a good opportunity presented itself of investigating the cause_of the outbreak. On communicating with Dr. Lynch, the Health Officer of the Port, asking his permission to visit the shipping and explaining my object, that gentleman readily granted my request, and in addition to offeying to place every facility in my way, was also good enough to give me his personal assistance in the enquiry. On visiting the ship we found that not only had there been five cases of cholera, but we were informed that a number of the crew had been suffering from diarrhoea, and the general impression was that the outbreak was due to entrance into the cholera zone and breathing a cholera air.
