82 EXPEEIMENT STATION RECORD. 



Schultz, or 5 per cent mallein can be employed. The complement fixation test 

 yielded more reliable results than the agglutination or precipitation metliods. 

 When practicable, it is deemed advisable to carry out the tliree tests on the same 

 blood sample, especially when questionable results are obtained by the comple- 

 ment-fixation test. If from 0.2 to 0.1 cc. of blood serum causes fixation, glanders 

 is present. Where partial fixation occurs the complement-fixation test should be 

 repeated, provided a negative reaction is obtained with the agglutination test. 



Out of 150 hor-ses destroyed on the basis of two positive thermal reactions 

 the three serodiagnostic tests showed glanders 132 times, in one case glanders 

 was suspected, and 17 ca.ses were negative. Among the 17 negative cases, how- 

 ever, there were found 9 animals with caseous and calcified nodules which could 

 not be positively recognized to be of a glanderous nature, and in 6 animals 

 acute glanders was found three to four weeks after the examination. Out of 

 25 hor.ses found glandered on autopsy 18 had given negative mallein tests, 20 

 were declared glandered by the serodiagnostic test, and one doubtful.

 (1914), ^^0. Jf8, pp. 777-779). — A comparatively complete description of tuber-

Im.inunizing tests on guinea pigs with tubercle bacilli dissolved by 

 lecithin, E. A. Lindemann {Coitbl. Bakt. [etc.], 1. Abt.. Orifi., 7Jf (liUlf), Xo. 

 7, pp. 62.'f-€34).— The favorable results reported by Deycke and Mucli (E. S. R.. 

 22, p. 184; 2.5, pp. 87, SSG) could not be confirmed in this investigation. In no 

 case was an immunity obtained.

Piroplasmosis in cattle in Hungary in 1913 and means of control. K. 

 WoliAk (Allatorvosi Lapoh; 37 (19 IJ,), Xo. 33, pp. 3S7-3S9; abs. in Intcnrnt. 

 Inst. Agr. [Rowc], Mo. Bui. Agr. Intel, and Plant Diseases, 5 (191^), Xo. 12, 

 pp. 1615, 1616). — It is stated that this disease of cattle is relatively rare in 

 Hungary and appears to be restricted to the wooded regions of the Northeast. 

 It has, however, appearetl of late years in the country on the left bank of the 

 Tisza, where it sometimes takes a virulent form. 



The daily administration of a mixture of 1 gm. of powdered arsenious acid. 

 10 gm. of powdered calamus root, and 10 gra. of sulphate of iron in a small 

 ration of bran is thought to have had a valuable curative action. 



The hog cholera question, with particular reference to shoat typhoid, R. 

 Standviss (Zlsclir. lufchtionshrank. ». Hug. Ifnuftticrc, 16 (191'>). Xo. 6, pp. 

 459-469, fig. 1). — The etiology and the clinical and patho-anatomical appear- 

 ances of hog cholera and " Ferkeltyphus " are considered. The author thinks 

 that for the present hog cholera should be referretl to without giving the sec- 

 ondary infection a separate name ; that shoat typhoid should be .separated 

 therefrom.

Facts about so-called hog cholera cures and specifics, C. H. Stance and 

 C. G. Cole (loica 8ta. Cire. 25 (1915), pp. 6). — This circular reports tests made 

 of seven different so-called hog cholera cures and specifics, none of which was 

 found to be of value. The products thus tested are Cholera Immune U. S.
