Vorwald It thus seems relatively easy as early as the beginning of the evolution of this phenomena of asbestosis what will keep the worker in good health By By contrast silicosis is not at all of the same nature It is caused by inhaling particles of free silica from one to five microns It produces a specific pathological lesion which is a " nodule My quotation marks The reaction caused by silicosis is not mechanical but chemical Silica established favorable ground for the evolution and development of tuberculosis Silicosis by its own nature is a progressive disease and its evolution generally leads to death It is proved that there isn't any free silica silica silica in the asbestos mines and that silicosis could not occur in the workers employed at mining for asbestos minerals The radiographic picture of asbestosis and of silicosis do not resemble each other at all and a slightly practised eye can ascertain right away this difference There cannot be any on this subject As for tuberculosis this is a known disease that is produced by inhaling tuberculosis bacillis called Koch's bacillis According to the testimony of Dr.
