    ¥ATER; ITS WORK OF PURIFICATION. BY ARTHUR RANSOME, M.A., M.D, rHE last two sessions I have lectured for the Manchester and Salford Sanitary Association on Air. The subject that has ?een assigned to me, in this year's series of Health Lectures, is Vater, and it would be hardly possible to choose a more important r nobler theme on which to discourse. It is indeed noble, in every sense that the word can be used. Vaier is one of the purest substances in nature, as Professor Vanklyn, the eminent chemist, has pointed out. Even the very oulest varieties of drinking water possess a high degree of purity, hen compared with other substances found in nature. It is rare )r a chemist to meet with chemical compounds that do not contain \e one-thousandth part of foreign matter, and even impure water ontains less than this. This is well shown in the following 'able:— ANALYSIS OF WATER. SOURCES, PARTS PER MILLION. FREE ALBUMINOIL- AMMONIA. AMMONIA. iChelsea .. Southwark Lambeth ..
