    SO cliaracteristic that, for practical purposes, a correct diagnosis could be made in a majority of cases witliout a knowledge of their microbic nature and the improved methods for making a positive diagnosis derived therefrom. Koch called special atten- tion to this fact, that the bacillus can be constantly found in tlie giant-cells and between the epithelioid cells in young tubercles, while it is more difficult to find it in cheesy products, unless caseation has taken place quite rapidly. Schuchardt and Krause Ueber das Vorkomraen der Tuberkelbacillen bei fungosen und scrofulosen Entziindungen. Fortschritte der Medi- cin, B. i, S. 277) examined forty cases of tuberculosis of bones, joints, tendon-sheaths, and the skin, in Volkmann's clinic, and never failed in finding bacilli, although in some specimens care- ful and prolonged search had to be made. W. Mueller and Watson Cheyne have demonstrated experimentally that typical tuberculosis of bones and joints can be made artificially in animals by injecting tubercular material or a pure culture of tu- bercle bacilli directly into the tissues or indirectly by the way of the arterial circulation. It must now be considered as an established fact, based on clinical observation and experimental research, that all lesions, including affections of bones and joints, in which the microscopical and bacteriological (;haracteristics can be found, must be regarded as tubercular in their origin and tendencies, thus establishing the microbic origin of tuberculosis upon a strictly scientific basis.
