DRINKING WATERS OF LONDON AND PARIS.
Believing that it would be a matter of interest to
compare the water supply of the two greatest capitals in
Europe, wc procured, by the agency of a Parisian chemist,
a supply of the Seine water, just as was delivered to
a house in the Rue St. Honore, on September 21, 1863.
It was bright, but contained threads of conferva, and
a few vegetable debris, which were separated by filtration
before analysis, which was effected by a professional
chemist.
The water supplied by the Grand Junction Company,
September 30, yielded—
Organic impurity
Inorganic
Total
1.70
