suggested that such nonacid-fast forms of bacteria Diight possibly be used for 

 immunizing purposes. They are also supposed to be less toxic than the other 

 strains. By injecting living branched forms it is possible to produce a marked 

 degree of immunity in guinea pigs. These facts are in accordance with the 

 results obtained in clinical work with a watery extract and the suspension of 

 degreased tubercle bacilli, which has been previously reported by another 

 author. 



A comparative study in regard to the resisting powers of the goat and 

 guinea pig against the tuberculosis bacillus, G. Sharaglini {Riv. Grit. Clin. 

 Med., 13 {1912), No. 3, pp. 37-41; ahs. in Ztschr. Immunitdtsf. u. Expt. Ther., 

 II, Ref., 6 (1913), No. 15, p. 1109).— The experiments were made with a very 

 susceptible guinea pig and a less susceptible goat and included the determination 

 of the opsonic index and agglutination. The leucocytes of the goat destroyed 

 the baceria very readily in vivo and in vitro. In the guinea pig the leucocytic 

 reaction was tardy and of a low order. The same dillerences were noted in the 

 agglutination. 



The blood findings in tuberculosis, Lydia Rabinowitsch (Berlin. Klin. 

 Wchnschr., 50 (1913), No 3, pp. 110-112; ahs. in Jour. Amer. Med. Assoc., 60 

 {1913), No. 9, p. 703). — "A report [of a] research which apparently confirms the 

 assumptions of Virchow and Orth, published 22 years ago, to the effect that 

 an injection of tuberculin is liable to rout out the tubercle bacilli from their 

 nests and drive them into the blood. In the numerous accounts that have been 

 published in the last few months of the findings of the bacilli in the blood it 

 is not stated whether the patients had been taking tuberculin or not. Bac- 

 meister has recently stated that inoculation of animals with the blood from 

 15 tuberculous patients gave constantly negative results, but after 4 of the 

 patients had been given a diagnostic injection of tuberculin with a distinct local 

 reaction, then the inoculation of animals all gave positive results. He added 

 that there can be no doubt that virulent bacilli had been driven out of the 

 diseased organ into the circulating blood by the injection of tuberculin, and 

 remarks that this is a pretty serious thing." 



La pataleta: Some observations on a disease of stock observed in the 

 southern territories of Argentina, J. M. Quevedo (Bol. Min. Agr. [Buenos 

 Aires'^, U (1912), No. 9, pp. 1030-1040, figs. 5).— This paper describes an affec- 

 tion of equines, bovines, and ovines which has been observed since 1907 in 

 Patagonia. The disease resembles the enzootic paraplegia of sheep, previously 

 described by the author (E. S. R., 28, p. 183), but differs In the species and age 

 of the animals attacked, the latter only occurring in adult sheep. 



Scrapie, an obscure disease of sheep, S. Stockman (Jour. Gompar. Path, 

 and Ther., 26 (1913), No. 4, pp. 317-327).— This article relates to a fatal disease 

 of sheep, which occurs on the borders of England and Scotland and is increas- 

 ing in prevalence, but about which but little has been known until recently. 

 It is characterized by intense itching, locomotor troubles, emaciation, and death 

 in from 3 to 4 months. As a rule the active symptoms are not met with except 

 in sheep over 18 months of age. When the disease is established on a farm the 

 losses from it often amount annually to 4 per cent of the sheep and may be as 

 high as 19 per cent. No remedy has been found up to the present time but 

 experiments with curative treatment are under way.

 Enslin and W. S. H. Clegiiorne (Agr. Jour. Union So. Africa, 7 (1914), No. 1, 

 pp. 25-29, figs. 10). — A description and plan are given of a circular dipping tank.
