One observer, the late Wilson Fox, has ad- mitted that he did not take care to isolate the animals (guinea-pigs) experimented upon from those undoubtedly tubercular, and here of course would be a probable source of infection by the bacilli. If a small nodule of caseous matter be placed in the outer chamber of the eye of a rabbit, it at first dis- appears, and three weeks after an eruption of miliary tubercles takes place on the iris (Cchnheim). 4. Is it Due to a Specific Cause ? Tubercle Bacillus.—This has been already described, but some further facts are important. a. It can be cultivated in sterilised ox-serum at a temperature of 86° to I05'8° F. b. Such cultivations may be injected into animals, and when so injected will set up acute miliary tuberculosis. [The most recent experiments tend to show that only when tubercle is introduced is tubercle produced.—Eds.] c. There is probably some tissue proclivity or general predisposition necessary for their growth. Some such reason as this seems necessary to account for the exemption from contagion ; then again, when
