In tuberculosis the con-glomerate tubercles cast round shadows on the usually clearareas of the lung, while the congested arteries and veins, infil-trated lymphatics and bronchioles leading to the areas involvedcast a distinctly linear detail in the areas between the con-glomerate tubercles and the lung hila. Furthermore the site ofprimary invasion in the lung is not at the apices, as so longtaught in text-books, but is in the lymphatic glands at the hilaof the lungs, and thence one can trace the spread of the diseasein radiating lines of infiltration to the apices or whatever partof the parenchyma may be involved.
