The "line of march" of tubercular lesions of the lungs is discussed in a most interesting way by Dr. J. K. Fowler, in the October number of the London Practitioner. The apical position of the primary lesion has been recognized almost as long as we have had exact information about diseases of the lungs. But the path and course of extension of the tubercular inflammation has been little studied. In 1882 Dr. William Ewarts' excellent Gulstonian Lectures on "Pulmonary Cavities" threw much light on the location and mode of growth of these lesions. He showed that cavities at the base of the lungs were very rare, that they occurred at the apex oftenest, in the dorso-axillary region a little less frequently, and in the mammary still less frequently, although in about one-half of all the cases.
Dr. Fowler aims especially to point out the order in which the tubercular lesions
