As epidemics of enteric fever are commonly traceable to infected
water, and as Croydon has two distinct sources of water supply, I
have once more compared the incidences of the disease in the parts
of the Borough supplied by Croydon and by Lambeth (Metropolitan
Water Board) water.
As the numbers for one year are small, the particulars have been
taken out for the ten years, 1900-1909 inclusive.
