(German), french slate contains 84$ combined silicates (drains, lias, magnesia, potash, etc.} and only 6-7$ free silicic add, Examination of 251 slate workers who bed been exposed to the dust under varying hygienic conditions revealed no signs of silicosis. The tendency to emphysema and chronic bronchitis is increased. Since the alete contains mush soridte, these findings do not indicate that sortcite Is tho chief oouso of silicosis. In spite of tho relative haxmlessness of tho dust, prophylactic measures are necessary. 432 SilicodB in the Steel foundry. L.X.Uerrltt.

Tripoli is the third sourco but in recent years, its use is on the docline. The best method of controlling dust from these materials is to prevent its formation or rcoovo it at Its sourco.
