the preparation for 24 hours with acetoue at a temperature of 50° C. and then 

 filtering the extract through paper gave good results. The extract obtained 

 was diluted with water, and the technique followed was that described by 

 Ascoli. 



The results of some tests with the sera of normal subjects and subjects 

 affected with tumors and other diseases are given. 



Auto serotherapy in pleuritis, P. Haan (Rev. Gen. MM. Vet., 21 (1913), No. 

 251, pp. G21-625; ahs. in Berlin. Tierarztl. Wchnschr., 29 {1913), No. 35, p. 

 628). — Although the application of the autoserotherapeutic method for sero- 

 fibrinous pleuritis is not new, it seems to be very little used by the practicing 

 veterinarian. In addition to the classical methods which use caffein, digitalis, 

 and other diuretics, and vesicants, the author used autoserotherapy directly 

 after the fluid was drawn from the thoracic cavity as suggested by Teppay (E. S. 

 R.. 2G, p. 6S4). The day following the administration of the thoracic fluid, 

 improvement usually set in, which manifested itself by a restoration of the 

 appetite. 



A considerable amount of fluid must be withdrawn from the thoracic cavity 

 because 40 cc. must be injected in the subcutaneous tissues of the same animal. 

 The dose may be repeated if a reaccumulation of the fluid in the cavity takes 

 place. If the method is used early, almost two-thirds of the horses affected may 

 be saved. 



A dry placenta powder and its use in Abderhalden's dialysis method for 

 cLiag'nosing pregnancy, V. L. King {MUnchcn. Med. Wehnschr., 60 (1913), No. 

 22, pp. 1198; ahs. in Berlin. Klin. Wchmchr., 50 (1913), No. 26, p. 1227).— A 

 preparation designed for use in the dialysis method (E. S. R., 28, p. 777) instead 

 of the wet placenta protein. 



The biolog'ical diag'nosis of pregnancy, E. Engelhoen (MUnchen. Med. 

 Wchnschr., 60 (1913), No. 11, pp. 587, 588; abs. in Berlin. Tierarztl. Wchnschr., 

 29 (1913), No. 26, p. 4^2). — The dialysis method was studied with human sera. 

 The conclusion drawn is that a reaction does not warrant the diagnosis that the 

 subject is pregnant. 



The serum diagnosis of pregnancy, C. C. W. Judd (Jour. Amer. Med. Assoc, 

 60 (1913), ^0. 25, pp. 1947, 19.^8). — A very general description of the test pre- 

 viously discussed (E. S. R.. 27, p. 577), with a statement in regard to the 

 satisfactory results obtained by its use. 



The serodiagnosis of pregnancy, K. Jawoeski and Z. Szymanowski ( Wiener 

 Klin. Wchnschr.. 26 (1913), No. 23, pp. 922-924; abs. in Berlin. Klin. Wchnschr., 

 50 (1913), No. 26, p. 1227).— The Abderhalden method, when conducted strictly 

 in accordance with the rules set down by the originator, gave satisfactory re- 

 sults in every instance. It was positive in the early days of pregnancy and it 

 was still present 14 days after parturition. In extra-uterine pregnancy the 

 reaction was positive when the ectodermal plates were still in contact with the 

 reproductive system. In hyperemesis or eclampsia (women) the reaction was 

 generally very faint. Sera from subjects suffering with carcinoma did not 

 cleave placenta protein. 



The diagnosis of pregnancy with, the optical method and the dialysis 

 procedure, R. Freund and C. Brahm (Miinchen. Med. Wch^ischr., 60 (1913), 

 No. 13, pp. 685-690) .—This is a study of the value of both the optical and the 

 dialysis method. In all there were 135 cases examined, and 6 of these were 

 eclampsia cases and examined twice. The optical method was tried 134 times 

 and the dialysis method 99 times. The subjects were normal pregnancies, extra- 

 uterine pregnancies, adnex tumors, and other nongravid cases. 



The clinical findings were parallel with the optical method in 97 out of 134 

 cases (72.4 per cent), and with the dialysis method in 66 out of 99 cases (66.7
