The New River Company has a storage capacity of 4•4 days'
supply. The average rate of filtration per square foot per
hour is 2•29 gallons, and the percentage of organisms left in the
water after filtration is only 2•2; West Middlesex coming next
with 2•5; while East London follows with 3•1; Chelsea 6•0,
and Grand Junction 8•9 per cent. While freely admitting the
superiority of the water of the New River Company over that of
all other Companies drawing water from the Thames or the Lee,
it is doubtful if any water which has been specifically polluted
can furnish, within a limited period of time, a perfectly satisfactory
domestic supply. There is no guarantee that filtration
will always be efficient; indeed careful scrutiny of the weekly
analyses show that it is not always efficient; filters are liable to
various accidents, and common sense would suggest the avoidance
of all risks, and give the preference to a water supply which
has never received the germs of infectious disease rather than
one which, having received them, must rely upon processes of
purification for their removal.
Mortuary.-During the year 253 bodies were brought to
the mortuary; 59 of these were Holborn Guardian cases, and
194 were brought from the dwellings of parishioners, including
16 cases of infectious disease; 121 were inquest cases upon
which 86 post-mortems were made
