sulphur trioxide per day.
These comparative figures may be summarized as follows:-
Total weight of deposit for year in tons per sq. mile | Daily average of sulphur over the year in milligrams of sulphur trioxide | |
---|---|---|
North Kensington | 207.82 | 2.56 |
South Kensington | 191.75 | 2.81 |

District | ||
Industrial area | 240.20 | 3.54 |
Readings from the two monthly stations in Kensington have now extended over three years, and it is possible to compare the results.
