WATER PURIFICATION

It is stated that since the New York Department qf Water Supply added a small amount of chlorine to the water not. a single case of typhoid fever has occurred which could be traced to the city water. A fur more remarkable achieyement in water purification, however, is presented by the equipment devised by British chemists for the use of the Army in France. It was so perfect, that an equipment on a barge could pump foul water from a canal and deliver it in Urge quantities purified tot drinking purposes. In view of the New York success, it is proposed that chlorinated water be used for sprinkling the streots to prevont the spread of infection. This proposal lias been anticipated to some extent by the Poplar Borough Council in the' East End of London, which for many years has provided, under the direction of the Medical Officer of jlealth, free supplies of such disinfectant produced l>y an electrical process. It is freely used for public baths and washhouses, for cleaning hospitals, and other public institutions,; for drains, end for other sani-' tary purposes. _ Electricity is passed through a solution of certain salts, con' verting the liouid into an effective noil* poisonous disinfectant, which can be' stored unimpaired for long periods.
