To make a satisfactory diagnostic test, the temperature of the animal should be taken every few hours for a day or two before the tuberculin is administered, in order that the normal diurnal and nocturnal variations of temperature shall be known. The tuber- culin is then administered by hypodermic injection into the shoulder or flank, and the terriperature subsequently taken every two hours for the next twenty-four hours. A reaction of two degrees beyond that normal to the individual animal is positive of tuberculosis. After one reaction of this kind the animal will not again react to an equal dose of tuberculin for a number of weeks. FOWL TUBERCULOSIS Bacillus Tuberculosis Avium The occasional spontaneous occurrence of tuberculosis in chickens, parrots, ducks, and other birds, observed as early as 1868 by_ Roloff*. Fig. 287.âBacillus tuberciilosis avium. and Paulicki,t was originally attributed to Bacillus tuberculosis hominis, but the work of Rivolta,| Mafucci,§ Cadio, Gilbert and Roger, II and others has shown that, while similar to it in many respects, the organism found in the avian diseases has distinct pe- culiarities which make it a-different variety, if not a separate species. Cadio, Gilbert, and Roger succeeded in infecting fowls by feeding * "Mag. f. d. ges Tierheilkunde," 1868. t "Beitr. zur vergl.
