Wherever capillaries occur, whether in the common vascular organs or in new tissues, there tubercles may present themselves. Certain vascular textures however, the muscles very particularly, arc more exempt than others. The bones even arc not free, although their liability had been long overlooked. The small blood-vessels are also liable to diflfused tuber- cular or as Dr. Hall terms it, fatty degeneration. To this degeneration, indeed, he ascribes the frequent early occun-ence of haimoptysis, literally from a broken ves- sel in tuberculous lungs, British and Foreign Medico- Chirurgical Review, April, 1855, p. 493. The lungs however, are the more particular place of tuberculous election, so much so that when tubercles occurred any- where, Laennec affirmed that pulmonary tubercles would also present themselves. But to this I have witnessed several exceptions, so that Laennec's law, if we may so term it, can be only looked upon as approxi- mativcly true. 8.
