cannot be a satisfactory inspection of butcher's meat. If private
slaughter-houses are allowed, the opportunities for deception are so
great, that no amount of inspection can prevent the sale of meat
from unsound animals."
It is on these grounds amongst others, which I humbly submit
to you that I am unable to agree with the opinion at which a
majority of the Vestry arrived, although my remarks must not
for a moment be taken as in any way calling in question the perfect
and undoubted right which the Vestry exercised in coming to the
decision which they did, and which decision has received an
authoritative sanction in the similarity of the view which has been
adopted by the Select Committee of the House of Commons.
Every month I place before you in my reports analyses both of
the water of the New River Company as taken from the works, as
well as of samples taken by myself from other parts of the main,
and also the quantity per head daily supplied by the company. It
may be interesting to know that, taking the whole of London, the
supply to each house during the year 1872 averages rather more
than 218 gallons per day, whilst per head of the population it ranges
from 30.5 gallons to 36.2. For this purpose about 60 million gallons
of each day's supply were derived from the River Thames, 4.5
million gallons from the New River and the River Lea, and the remainder
from the deep chalk wells of the Kent company.
The average chemical composition of the water, of the New
River company during the year 1872 is as follows:—
