There is no spot in this country in which the cholera was more fatal during the epidemic of 1832 than the village of Newburn, near Newcastle-upon-Tyne. We are informed, in an excellent paper on the subject by Dr. David Craigie,[8] that exactly one-tenth of the population died. The number of the inhabitants was five hundred and fifty; of these, three hundred and twenty suffered from the epidemic, either in the form of diarrhœa or the more confirmed disease, and the deaths amounted to fifty-five. Being aware of this mortality, I wrote, about the beginning of the year 1849, to a friend in Newcastle—Dr. Embleton—to make inquiries respecting the water used at Newburn, and he kindly procured me some information from the Rev. John Reed, of Newburn Vicarage, which I received in February, as well as an answer from Mr. Davison, surgeon, of Newburn, to whom I had written in the meantime. I learnt from these communications that the people were supplied with water in 1832, as they still were, from three wells, two of which were very little used, and that the water in the third well was derived from the workings of an old coal-mine near the village. The water of this well, as I was informed, although generally good when first drawn, became putrid after being kept two days. It was considered that the evacuations of the people could not get into any of the wells; but the vicar thought that the water of a little brook which runs past the village, and falls into the Tyne immediately afterwards, might find its way into that well which is chiefly resorted to. Putrefaction, on being kept a day or two, is so much the character of water containing animal matter, that, after receiving confirmation of my views respecting the communication of cholera by water from many other places, I wrote to Mr. Davison again on the subject, and he kindly took a great deal of trouble to investigate the matter further. He informed me that the brook was principally formed by water which was constantly pumped from coal-pits in the neighbourhood. About half a mile before reaching Newburn it received the refuse of a small village, and between that village and Newburn it ran through a privy used by the workmen of a steel factory. In Newburn this brook received the contents of the open drains or gutters from the houses. The drain which conveyed water from a coal mine or drift not worked for a great number of years, to the well mentioned above, passed underneath the brook at one part of its course, and from that point ran alongside of the brook to the well,—a distance of about three hundred yards. Mr. Davison said that it was disputed whether there was any communication between the drain and the brook, but that it was highly probable that there might be; and that an occurrence which took place a few months previously seemed to prove that there was. Some gas-water from the steel manufactory mentioned above got by accident into the brook, and some of the people affirmed that the water in the
