and urotropin. The results obtained, however, do not indicate that any of these 

 drugs possess any value whatever either as ti prophylactic or in the treatment 

 of spotted fever, but on the contra i-y their administration seems on the whole 

 rather to intensify the severity of the disease in the animals as compared with 

 the course of the disease in the controls." 



A bibliography of 76 titles is appended. 



Ag'glutination, precipitation, and complement fixation as an aid for diag- 

 nosing trypanosome diseases, especially dourine (Beschalseuche), Winkleb 

 and S. Wyschelessky (Berlin. Tierdrztl. Wehnschr., 27 (1911), No. 51, pp. 

 933-936). — The above mentioned reactions can be used for diagnosing these 

 conditions. 



[Transmission of Trypanosoma hippicum] (Rpt. Dept. Sanit. Isthmian 

 Canal Com., 1912, Feb., pp. 41-^3). — Exi^eriments here reported "indicate very 

 positively that T. hippicum can penetrate the mucosa of mules, which in the 

 mouth and vagina is much thicker in proportion to the length of ti'ypanosome 

 than that of guinea pigs and rats used in other exjjeriments, and it is assumed 

 from this that murrina may be transmitted during copulation." 



[Investigations of Tiypanosoma hippicum] (Rpt. Dept. Sanit. Isthmian 

 Canal Com., 1912, May, pp. J^l-IfS). — "A strain of T. hippicum that had survived 

 in a guinea pig the exceptionally long period of 336 days showed upon sub- 

 inoculation on the two hundred and seventy-ninth and three himdred and thirty- 

 sixth days very feeble pathogenic powers when compared with all otlier strains 

 and with the same strain at an earlier period of the infection in the guinea 

 pig." 



Diagnosis, prevention, and treatment of tuberculosis, S. J. Bonansea 

 (Diagnostico, Prevenci6n, y Curaci&n de la Tuherculosis. Mexico, 1911, pp. S^Jf, 

 figs. 23). — This is a general summary of the methods of diagnosing, preventing, 

 and treating tuberculosis in animals. Mexican conditions are considered in 

 particular. 



The relation between human and animal tuberculosis, H. Kossel (Deut. 

 Med. Wchn^schr., 38 (1912), No. 16, pp. 7.'/ 0-74-'/). —In an address before the 

 Seventh International Tubei-culosis Congress, held at Rome, the author main- 

 tains that the greatest source of infection for pulmonary tuberculosis in man 

 is man himself, particularly because the human tyi>e of bacillus is almost 

 always present. Very little tuberculosis has its origin from the consumption 

 of milk and meat obtained from tuberculous animals. Therefore, when com- 

 bating tuberculosis as a national disease it is necessary to direct efforts 

 principally to human infection. 



In regard to bovine and human tuberculosis, J. Orth (Sitzher. K. Preuss. 

 Akad. Wiss., 1912, VII, pp. 155-179). — A critical and historical discussion. 

 Great stress is laid upon the point that tuberculosis in the human race can 

 never be eliminated as long as the bovine type of the bacilli is conveyed from 

 animal to man. 



Differentiating the human type of tubercle bacillus from the bovine type 

 by cutaneous injection of the guinea pig, E. Tomarkin and S. Peschi6 (Deut. 

 Med. Wchnsclir., 38 (1912), No. 22, pp. 1032-1034) .—More skin infections were 

 obtained (through shaved but intact skin) with the bovine type of bacillus 

 (26 out of 26 animals) than with the human type (7 out of 52 animals). The 

 method can therefore be used for differential diagnosis. 



The presence of tubercle bacilli in the circulating blood. — The elimination 

 of tubercle bacilli in the milk of tuberculous women, T. Kurashige. R. 

 Mayeyama, and G. Yamada (Ztschr. Tuberkulose, 18 (1912), No. 5, pp. 1,33- 

 1,45). — The elimination of tubercle bacilli in the milk of 20 tuberculous women, 

 and in 2 cases which apparently were nontuberculous, was noted. The chief
