The'Medical Officer of 'Health for the City of London, in

his 'Annual Report -for 1921, draws attention •to the methods which have been -employed to measure the amount of dirt in the atmosphere-of-the City. In June alone 54 tons of dirt of -various kinds-were deposited on an area of one square mile. In this mass of 'dirt about eighteen tons were soluble • chemicals and the insoluble remainder consisted of tar, soot and grit. How long are we going to allow this --constant rain of dirt to con- tinue ? It is a blight that -shuts out the pure rays of -the sun. All doctors are, in a way, sun-worshippers -to-day—some of them -are almost idolaters. Until we 'cleanse our -atmosphere by prohibiting the discharge of :smoke -from chimneys we -shall not be truly healthy or • -tialy prosperous.
