Impurities of water in relation to Typhoid Fever

At the request of the sanitary officer of the Launceston Corporation I have, at different times, examined 11 samples of water collected by him during his enquiries into outbreaks of typhoid fever ; to the results - obtained I shall refer later on, only stating now that they show painful neglect of the simplest necessary health precautions ; some of the figures are given in the table before you, also analyses of Hobart and other waters for comparison.
