    I may premise that I have for many years past regularly examined the quality of the water sup- plied by all the Water Companies to the metropolis, and the results have been published monthly by the Metropolitan Association of Medical Officers of Health. The average of these results for the eleven months of the present year are shown in the Table Xo. I.; and they indicate a very satisfactory condition of the water supply, both as regards the quantity and chemical quality of the water. At the present time, the average daily supply of water to the metropolis, is nearly 93 millions of gallons. This is at the rate of rather more than 200 gallons per house, or over 30 gallons per head. In the year 1851, when there was a Government Commission appointed to inquire into the condition of the Metropolitan Water Supply, it was found that the average daily supply to the whole of London, was onlv a little more than 45 millions of gallons. This was at the rate of about 19 gallons per head. In the course of sixteen years, there- fore, the amount of water daily supplied to the metropolis, has been more than doubled; and the proportion per head has risen from 19 gallons to 30.
