high agglutinating power, and came Erom dogs which had been inoculated with cul- 

 tures of tuherele bacilli obtained from birds. 



It is not considered necessary, however, to conclude thai there are differences of 

 nature or origin in tubercle bacilli from the observation of variations in agglutina- 

 bility. A culture of avian tubercle bacilli which is not agglutinable can not be used 

 for serum diagnosis. 



Pseudo-tuberculosis in sheep, .1. A. Gilruth (New Zealand Dept. Agr., Div. Vet. 

 Sci. J!"/. 1, pp. ■■'-/*■ — This disease affects sheep, goats, guinea pigs, and rabbits, but 

 cattle seem to be immune. The virus is greatly attenuated by passage through rab- 

 bits. The disease progresses from one lymph gland to another and ultimately 

 affects the lungs with a course somewhat similar to that of tuberculosis. 



The similarity in the pathogenic properties of the bacillus to those of the tubercle 

 bacillus is shown in the general appearance of the nodules, the progression of the 

 disease, and the invasion of the lungs. Brief notes are also given on the literature 

 relating to this disease. 



A systematic list of articles relating to tuberculosis, P. Bodchez (Rev. Tuber- 

 culose, 11 (1904), No. 4, j>]>. 310-328). — An elaborate list of books, memoirs, and 

 periodical articles published during 1904 on the various phases of tuberculosis of 

 animals and man. 



Cadaveric hyperthermia in Texas fever, J. B. P. Bey ( Com.pt. Rend. Soc. Hi"/. 

 [Paris'], 56 i 1904 \, No. IS, pp. 606-608). — During the tirstlew hours after death from 

 Texas fever it was observed that the temperature of the carcasses of Egyptian cattle 

 sometimes passed 44° C. Detailed notes are given on a number of such cases. It is 

 hoped that further studies will make it possible to find a satisfactory explanation of 

 this phenomenon, which is comparable with phenomena observed in cases of Asiatic 

 cholera in man. 



Cattle ticks and Texas fever, C. L. Willoughby ( <<>ni-<ji<i sin. Huh t;.}, pp. 

 143-182, figs. 9). — Texas fever is said to cause an annual loss- in Georgia of between 

 3 and 5 per cent of the total valuation of cattle in the State. Attention is called to 

 the susceptibility of tick-free native cattle and to the great losses which occur among 

 such animals. The Government quarantine line is described and notes are given 

 on the life history of the cattle tick, influences which affect ticks, methods of exter- 

 minating them, symptoms of Texas fever, treatment of the disease, immunity by 

 various methods, and a historical statement of inoculation work done in southern 

 States. 



The author believes that the South is the best place for inoculating infested cattle, 

 since they can be shipped south in winter and may thus become accustomed to the 

 climate before inoculation. According to the author, Mr. B. W. Hunt was among the 

 first investigators to work out a successful method for immunizing cattle against Texas 

 fever. In 1886 Mr. Hunt observed that one attack of the disease conferred immu- 

 nity and that on his own farm certain pastures were more dangerous to northern 

 cattle than others. He therefore used these places as immunizing calf pastures and 

 developed a method of immunizing young cattle without loss. 



The author carried on a number of experiments in inoculating northern cattle 

 during the years L903 and 1904. Nearly all of these cattle were young, most of them 

 from "i to 10 months of age. The calves were inoculated with 1.] to - rv. of the blood 

 of recovered animals. During these experiments it was found that such blood does 

 not always produce inoculation fever. No losses were suffered from inoculation 

 when performed under proper conditions and the animals subsequently subjected to 

 tick infestation successfully resisted the disease. From these experiments it is 

 concluded that southern stock breeders can control Texas fever if they will make an 

 intelligent use of the methods which have thus far been tested. 



It is believed to lie possible to disinfect pastures and keep them free from ticks; 

 or if another method is preferred home raised or imported cattle may be immunized
