Thus, again, it differs from the reaction due to the free crystalline silica In the form of quartz. i i Furthermore, this asbestosls, this aluminum hy- droxide or aluminum, colloidal aluminum hydroxide did not prevent the development of the reaction to the asbestos fibers deposited in the lung. If anything, our experiment al evidence, and that is also supported by the evidence fra King in England and his co-workers, is that aluminum hydrox ide augments the fibrosis due to the asbestos fiber* I.
