LONDON’S GREAT DEPOSIT.

OVER FIFTY TONS IN MONTH. Dr. Howarth, the medical officer of health for the City of London, alludes io his annual report to instances of smoke nuisance or annoyance from chimneys. These cannot be satisfactorily' dealt Avith until the enactments at present in force are strengthened or amended. Much dirt and discomfort from smoke continues, although to a distinctly less extent'than in former years. In February the quantity of deposit registered as falling in the city amounted to no less than about 57 tons avoirdupois. Of that mass of dirt 116.3 tons were soluble and 30.7 ton.-? were insoluble and consisted of tar, carbon and grit. These results are ascertained from the collection monthly of rain Avater from a known area of surface. This rain Avater, containing the soot, grit and dust washed from the air, is submitted 'or examination to the public analyst, and the results ' tabulated. Similar observations are made in the Archbishop’s Park at Lambeth by the London County Council.
