Abstract
IN a former paper read at the Congress of the Sanitary Institute held at Leeds in 1897 an account was given of the quantity of soot suspended in and deposited from the atmosphere of Leeds. It was then shown that, on the average working day, 20 tons of soot are sent into the air of Leeds, of which half a ton falls on an area of four square miles, and of the latter from 20 lb. to 25 lb. stick, that is, are not removable by rain. The present paper contains a record of the atmospheric impurities carried down by rain and the effect of this rain water on vegetation. It also contains an inquiry into the diminution of daylight caused by suspended particles of soot.
