    tubercle is hereditary in a family, it often does not break out for many years. The above suggestions will explain this; probably it does no harm until the tissue be in some way injured. [We are justified in believing that the bacillus tuber- culosis is the cause of all tubercular processes. Its presence, at least in the early stages, rather than any especial anatomical structure, must be the essentia! characteristic of tubercle.—Eds.] [According to this theory, tuberculosis may be acquired by inoculation^ inhalation, or swallowing. a. Inoculation.—Comparatively rare, and usually causes a local lesion only. b. Inhalation.—By far the most common source of infection. The bacilli, or rather their spores, may be found in air-borne dust, especialty in rooms occupied by phthisical persons. The daily sputa of a single patient may contain twenty million bacilli, which will retain their virulence for months (Bollinger). c. Swallowing.—The following may be received into the alimentary canal :— (i.) Milk from a tuberculous cow. Tuberculosis of the udder, in the form of softening nodules, is not uncommon among milch cows; again, absence of complication of the udder does not ensure safety; there is experimental evidence to prove that bacilli may be present in the milk from tuberculous cows in which the udders are unaffected, and also that tuberculosis may be imparted to young animals by the use of such milk.
