To Professor Frankland's valuable report, the main features of
which I have thus summarised, are appended numerous tables
setting forth, in detail, the various information condensed in the
text. I subjoin, as of greatest general interest, Table M, which
exhibits the

But it is not to Professor Frankland alone that we are now indebted
for information respecting the water we drink, many very
interesting facts being supplied by Major Bolton, R.E., the water
examiner appointed by the Board of Trade, under the provisions of
the Metropolis Water Act, 1871. Major Bolton's reports, which, by
his courtesy, I receive every month, afford information on all points
relative to the machinery for water supply, and to the provisions
already made, or in progress, for giving a constant supply, the
main object of the Act; and which, I suppose, we may, at some
remote future, hope to obtain. As the information in question is
not generally accessible, I make no apology for presenting a
resume of it on this occasion. And, first, with respect to the constant
service, we learn that the West Middlesex Company are
giving constant supply to a number of houses, on the application
of the owners, and are fully prepared to extend the supply when
called upon. Extensive works and additional engine power of 120
horse power are in course of construction at Hampton.
The Grand Junction Company have formed a high service reservoir
near Kilburn, to contain 6,000,000 gallons, for constant service,
and are completing the line of main pipes to connect up this
reservoir with the works at Campden-hill; they are likewise erecting
boilers and works at Hampton, for which place an additional
70-inch engine of 125 horse power is being constructed, and an
extra 30-inch main from Hampton to Kew has been ordered to be
laid down. The Chelsea Company does not appear to have taken,
as yet, any steps in this matter, having, as we shall see, other and
