The first and second samples were taken from two wells in the rear of a block having about twenty occupants. An inspection of the back yard and alley showed an immense amount of filth. There was no sewer to carry away slop or excrementitious matters. A large privy vault was in the rear of the block. There was one well north and another south of the vault, and about twenty feet from it. These wells supplied the water to the occupants of the block. Six cases of scarlet fever were there developed and three of them died. The other persons in the block were constantly ailing. One of the leading physicians of the city attributed the outbreak of the fever to the bad surroundings and the impure water. The third sample was taken from a well on East Walnut street. The family using the water were more or less sick all the time. Languor, loss of appetite and spirits, sleeplessness, or nightmare, morning diarrhœa, headache and nausea, one or all, continually annoyed those drinking the water. The privy vault, twelve feet deep was forty feet northeast of the well. The fourth sample was obtained from a well on North Tennessee street. Throat affections, fevers, diarrhœas, headaches with malaise, etc., made up the list of the complaints of the family using the water. The fifth sample came from a well on North Alabama street. During the last three months, among those who drank the water there were three who had scarlet fever—one of whom died. And so on similar reports can be made of the other samples, except those marked “good” or “excellent.” SANITARY ANALYSIS OF WELL WATERS.
