    The following analysis of the different waters supplied to the Borough may be of some interest. University College, Liverpool. I have analysed the sample of water received from J. W. M. Eichardson on the 18th day of October, 1897, with the following results, expre.ssed in parts per 100,000. Mark and denomination of the sample. Spring Hill. Flavbrick Hill. Borough Road. Prentun.

J. CAMPBELL BEOWN, D.Sc. The sann)les are all good for domestic use. As far as bacteriology is concerned, the ISpring Hill AVell is most perfect and the Borough Hoad the next, liut none are bad. In my opinion Flaybrick Hill will he the first to become doubtful. 25th October, 1897. P.S.—There is much magnesian hardness in these waters. M'^hen that is the case, it is a donl)tful question how the hardness should be stated.
