the relation of the surface tension of an immune serum to the surface tension 

 of an antigen. It is conducted with the aid of Traube's stalagometer (E. S. R., 

 23, p. 217), in which the serum of the patient, the antigen, and a normal serum 

 dihited with an 0.85 per cent solution of sodium chlorid are compared in regard 

 to the number of drops coming from the instrument under the same conditions 

 and in a given period of time. The observations are made as soon as the 

 apparatus is filled with the serum and again after 2 hours of incubation at 



37° C. 



Some results with typhoid serum are given. 



Meiostag'min reaction with m.alig'nant growths, M. Ascoli and G. Izab 

 (Miindien. Med. Wchnschr., 57 {1910), No. S, pp. .'(03-405, • abs. in Hyg. Rund- 

 schau, 21 {1911), No. 1, pp. 24, 25). — The results show that diluted serum from 

 rats affected with sarcoma when mixed with diluted sarcoma antigen has a 

 lower surface tension than diluted normal rat serum. Some results are also 

 given for cases of human sarcoma. The results with malignant growths were 

 regularly positive. 



Clinical experience with the meiostagmin reaction, G. Izae {Munchen. 

 Med. Wchnschr., 57 {1910), No. 16, pp. 842-81,4; ahs. in Hyg. Rundschau, 21 

 (1911), No. 1, p. 25). — The reaction gave positive results in 34 out of 35 posi- 

 tive cases of tuberculosis. Other cases which had a positive cutaneous reac- 

 tion, but a negative finding in regard to tubercle bacilli, were also positive. 

 Cases of typhoid, ankylostomiasis, and echinococcus (7 pigs and 3 cows) also 

 yielded positive results. On the other hand, sera from 2 subjects which had 

 anthrax 2 months previous to the test gave negative results. 



Alimentary anaphylaxis, C. Richet {Compt. Rend. 8oc. Biol. [Paris], 70 

 {1911), No. 2, pp. 44-46). — Dogs which took crepitin through the alimentary 

 tract were fovmd to be strongly anaphylactic against an injection of crepitin. 



Serodiagnosis of pregnancy, G. Lemaire and Laffont {Compt. Rend. Soc. 

 Biol. [Paris], 69 {1910), No. 31, pp. 337-339) .—The authors were not able to 

 diagnose pregnancy with either the precipitin or the complement binding 

 reaction, using amniotic fluid as the antigen. 



A contribution to the etiology of Aujeszky's disease, Schmiedhoffee 

 (Kozlem. Osszehasonl. Elet es Kortan Eorebol, 10 (1910), Nov. 5; abs. in Rev. 

 Gen. Med. V^t., 17 {1911), No. 196, p. 232).— Observations made of this disease 

 in bovines, cats, and dogs in Hungary are first reviewed. The authoi' finds 

 that the virus, which passes through very porous filters only, occurs in greatest 

 abundance at the point of inoculation, next in the blood and in the central 

 nervous system. The liver, spleen, and kidneys were at times found to be 

 infectious, as was the urine in 2 or 3 cases. The resistance of the virus is 

 very weak. Rabbits and guinea pigs are the most susceptible of the laboratory 

 animals. The carnivora and ruminants are also very susceptible, solipeds being 

 much less so, while the hog, pigeon, and fowl are refractory. The shortest 

 incubation period is found in the rabbit in which it is less than 20 hours, the 

 longest in the horse in which it is 10 days. 



Treatment through the subcutaneous injection of antiseptic solutions at the 

 point of inoculation, followed by the use of atoxyl and quinin, was ineffective.
