However, there will usually be a long history ofoccupational exposure to dust and there is little or no clinical evi-dence of a process as extensive as the roentgenogram would indicate,the mottling is more dense and the areas are smaller, more .sharplydefined, and more uniform in size than of tuberculosis. Another form of this disease is seen frequently in gold mine andpottery workers, and appears as a diffuse process involving bothjungs,particularly the upper lobes, and from the plates alone cannot bedistinguished from fibroid phthisis. 150 THE CHEST BIBLIOGRAPHY.
