It was quite otherwise in a cartridge factory at No. 38 Broad Street, where about two hundred work people were employed, two tubs of drinking water having been kept on the premises and always filled from the Broad Street pump. Among these employees eighteen died of cholera. Similar facts were elicited for other factories on the same street, all tending to show that in general those who drank the water from the Broad Street pump well suffered either from cholera or diarrhœa, while those who did not drink that water escaped. The whole chain of evidence was made absolutely conclusive by several remarkable and striking cases, like the following: "A gentleman in delicate health was sent for from Brighton to see his brother at No. 6 Poland Street, who was attacked by cholera and died in twelve hours, on the 1st of September. The gentleman arrived after his brother's death, and did not see the body. He only stayed about twenty minutes in the house, where he took a hasty and scanty luncheon of rump steak, taking with it a small tumbler of cold brandy and water, the water being from Broad Street pump. He went to Pentonville, was attacked with cholera on the evening of the following day, September 2d, and died the next evening. The death of Mrs. E. and her niece, who drank the water from Broad Street at the West End, Hampstead, deserves especially to be noticed. I was informed by Mrs. E.'s son that his mother had not been in the neighborhood of Broad Street for many months. A cart went from Broad Street to West End every day, and it was the custom to take out a large bottle of the water from the pump in Broad Street, as she preferred it. The water was taken out on Thursday, the 31st of August, and she drank of it in the evening and also on Friday. She was seized with cholera on the evening of the latter day, and died on Saturday. A niece who was on a visit to this lady also drank of the water. She returned to her residence, a high and healthy part of Islington, was attacked with cholera, and died also. There was no cholera at this time either at West End or in the neighborhood where the niece died. Besides these two persons only one servant partook of the water at West End, Hampstead, and she did not suffer, at least not severely. She had diarrhœa." Dr. Snow's inquiry into the cases of cholera which were nearer other pumps showed that in most the victims had preferred, or had access to, the water of the Broad Street well, and in only a few cases was it impossible to trace any connection with the pump. Finally, Dr. Snow made a statistical statement of great value which is here given in its original form: THE BROAD STREET, LONDON, WELL AND DEATHS FROM ASIATIC CHOLERA NEAR IT IN 1854
