Opal (anorptous silicic add) was also injected and the results were large deposits of dust with many giant cells, but no fibrous tissue. Opal is acre soluble than quartz; therefore, the conclusion is made that the dissolved dd2.de acid is not the fibreus-producing substance alone. Quartz is the onlj^roft^nce producing silicosis.
