These dusts contain oxide of aluminum, which is- imt easily dissolved in the tissues and which therefore m ust be coughed up. Constant exposure tp such dust causes re peated inflammations of the tissues of the lungs and a type of bronchitis which becomes chronic and serious. ..If is, of course, difficult to tell the difference between, bron chitis caused by dusts and th a t which results fro m -exnosure at hot furnaces and that due to the fumes th rt arise in various industries, or indeed th at due tp , severe climatic conditions. - , , . .. . ' Apparently the most harmful of all dusts is th a t de veloped in the industries using silica. Particularly tho& pa^ sociated with basalt and asbestos. The dust of asbestoe acts in connection with, the tissue of the lung to. cause a thickening or fibrous condition of the lungs which goes, on. , rapidly'to a serious if not fatal condition. . ,, , Coal dust does not apparently produce a n y unusoti ;/i mortality from respiratory disease.
