    your interference. Accordingly, I submit a tabular statement of twelve determinations of water, taken from the pumps at Bartholomew Lane, Aldgate (at the junction of Leadenhall Street with Fenchurch Street), Crutched Friars, and Fann Street—these four being the only pumps to which the public have free access in the City of London. There are several others upon private ground, amongst them being two on the premises of the East and West India Dock Company's Warehouses in Jewry Street, one in Monkwell Street, one in Christ's Hospital, &c., &c. These are all that remain of the 35 pubhc pumps which were in use in the City in 1866, some of which were condemned by my predecessor and closed by the Local Authorities, whilst others have become dry by the construction of the deep sewers and subways since completed, which have utterly exhausted the sources of the supplies to the surface wells in connection with them. These surface wells vary from 25 to 30 feet in depth. To the table below I have prefixed the results derived from a chemical examination of three samples of good waters, by way of comparison.
