Contagiousness of Malta fever {Jour. Amer. Med. Assoc, 55 {1910), No. 2.'i, 

 p. 2074). — The value is pointed out of using cultures killed with formaldehyde 

 vapors in laboratories where the agglutination test for Malta fever is carried 

 out. As this disease has increased in France, it is recommended that milk ob- 

 tained from goats be boiled and, further, that the importation of goats from 

 Malta be prohibited. 



"Muhinyo," a disease of natives in Uganda, D. Bkuce et al. {Proc. Roy. 

 Sac. [London}, Set: B, S2 {1910), No. B 558, pp. 485-.'i90, fig. i).— The authors 

 conclude that " muhinyo " is Malta fever and that it is conveyed from goat to 

 man by the drinking of goats' milk. 



Combating- tetanus in animals with specifi.c tetanus antitoxin, H. Holteb- 

 BACH {Beat. TierdrzU. Wcluischr., 18 {1910), Nos. 31, pp. 4.57-460; 32, pp. 

 469-.'i75; abs. in, Ztsclir. Immuiiitdtsf. u. Expt. Tlier., II, Ref., 3 {1910), No. 1, 

 p. 539). — The unfavorable results obtained from tetanus antitoxin by some 

 veterinarians are probably due to employing too small amounts of the serum. 

 The curative dose per kilogram of body weight is one antitoxin unit. This dose 

 may be repeated as often as necessary. Prophylactically, from 100 to 200 units 

 are necessary at one injection. 



Experiments to ascertain if cattle may act as a reservoir of the virus of 

 sleeping sickness (Trypanosoma gambiense), D. Bruce et al. {Proc. Roy. Soc. 

 [London], Ser. B, 82 {1910), No. B 558, pp. ^SMS-)).— " It has been proved by 

 experiment that cattle may act as a reservoir of the virus of sleeping sickness, 

 and that healthy animals may be infected from them by means of Glossina 

 palpalis. It has also beeu proved that cattle in the fly area do naturally harbor 

 T. gambiense. It is, therefore, possible that the cattle and antelope living in 

 the fly area may act as a reservoir and so keep up the infectivity of the G. pal- 

 palis for an indefinite period, but there is no proof up to the present that this 

 actually takes place in nature." 



Trypanosome diseases of domestic animals in Uganda, I— III, D. Bruce 

 ET AL. {Proc. Roy. Soc. [London], Ser. B, 82 {1910), No. B 558, pp. I,68-Ji79, 

 pis. 2; Ser, B, S3 {1910), No. B 561, pp. 1-27, i)ls. 5, figs. 2).— The first paper 

 deals with Trypanosoma pecorum, the second with T. brucei, and the third with 

 T. vivax. 



The conclusions drawn are that " T. pecorum is au important trypanosome 

 disease of domestic animals in Uganda. It is similar in morphology, action on 

 animals, and cultural characters, to the T. dimorphon described by Laveran and 

 Mesnil, and to Edington's trypanosome from Zanzibar [E. S. R., 21, p. 581] 

 except that T. pecorum is not pathogenic to guinea pigs. The carrier is 

 unknown, but is probably a Tabanus, and not Stomoxys." 



" The commission consider themselves .iustified in considering the trypanosome 

 recovered from the Uganda ox to be identical with T. brucei, the cause of 

 nagana in Zululand and other parts of South Africa. . . . T. vivax, an easily 

 recognizable species, gives rise to a fatal disease of cattle in Uganda. The car- 

 rier of T. vivax is probably Glossina palpalis, which is found naturally infected 

 on the lake shore. The reservoir of the virus is possibly the antelope which 

 frequent the G. palpalis area." 



Contribution to experimental tuberculosis in sea fishes with studies in 

 regard to the transmutation of tubercle bacillus of warm-blooded animals, 

 L. VON Betegh {Centbl. Bakt. [etc.], 1. AM., Grig., 54 {1910), No. 3, pp. 211-216; 

 abs. in Internat. Centbl. Gesam. Tuberkulose Forsch., 4 {1910), No. 12, p. 633). — 

 Some of the eels utilized in the experiments were inoculated intramuscularly, 

 and others intraperitoneally, with bacilli from man, cattle, birds, and fresh- water
