888 EXPERIMENT STATION RECOED. 



infection can be obtained, but not an absolute protection since carbolic acid itself 

 has some effect upon the antigen. 



The possibility of utilizing glycerol cultures as a vaccine against swine plague 

 was proved. Precaution, however, must be taken that the glycerol and culture 

 are present in the ratio of 1 : 1. An excess of glycerol must be avoided. 



Investigations in regard to the agglutination of paratyphoid and pestifer 

 strains, Teodorascu {Ztschr. Imnmnitdtsf. u. Expt. Ther., I, Orig., I4 {1912), 

 N-o. €, PI). 639-6Ji6; abs. in Centbl. Bakl. [etc.^, 1. AM., Ref., 54 (1912), Beiheft, 

 pp. 83, S4)- — ^A number of strains of the organisms belonging to the paraty- 

 phoid group were isolated from man and pig, and compared as regards their 

 agglutinating properties with paratyphoid, suipestifer, Voldagsen, and Glilsser 

 serums. The results agree well with those obtained previously by Haendel and 

 Gildemeister (E. S. R., 26, p. 785). 



The effect of wheat eating by horses, W. T. Kendall (Aust. Farm and 

 Home, 21 (1912), No. 8, pp. 3^6, 348). — The author, having conducted a series of 

 feeding experiments on horses, here gives a brief account of the symptoms. 

 causes of death, and treatment. 



A contribution to the study of infectious epididymo-vaginalitis of the 

 liorse, C. Medynski (BuI. /S'oc. Cent. Med. Vet., 89 (1912), No. 4, pp. 99-106).— 

 The author reports clinical and laboratory studies made of this disease, first 

 recognized and studied in Havre by Vallee, Lesueur, and Lavergue in 1905° and 

 by Guido Fiuzi in 1910 (E. S. R., 24, p. 485). He finds that the serum from 

 sick or convalescing animals agglutinates Vallee's bacillus in a dilution of 

 1 : 200 whereas at the onset of the disease agglutination took place only at a 

 dilution of 1 : 10. The injection of diseased animals daily for a period of 5 

 days with 100 cc. of serum obtained from a convalescing animal resulted in 

 rapid improvement. 



Certain concretions in a cyst of the mammary gland in a horse, A. 

 ScHEUNEKT aud W. Grimmer {Hoppc-SeyJer''s Ztschi: Physiol. Chem., 76 (1912), 

 No. 4, pp. 322-329; abs. in Jour. Chem. 8oc. [London], 102 (1912), No. 592, 11, 

 p. 186). — The concretions examined gave the following percentages: Water 

 69.0, protein 4.5, fat 13.7, cholesterol 10.0, lecithin 0.7, and ash 1.7. The fat 

 somewhat resembled colostral fat, being intermediate between milk fat and 

 the body fat of the horse. Casein was absent. 



Check li^t of helminths parasitic in equines, R. T. Leiper (Jour. London 

 School Trop. Med., 1 (1912), No. 1, pp. 22-26). — Systematic and alphabetical 

 lists are given. See also a previous note (E. S. R., 27, p. 583). 



Beport of the bacteriological institute of the agricultural chamber of 

 Hheinisch Prussia (Jahresber. Landw. Kammer Rheinprovinz, 1911, pp. 

 70-76). — This is a reix)rt in regard to the activities of this institution for the 

 year 1911. It deals with the results of combating tuberculosis in animals; 

 tests in regard to combating various infectious diseases, such as vaginal 

 catarrh; determination of the cause of death in animals; and destruction of 

 mice, rats, etc., with mouse typhoid cultures. 



RURAL ENGINEERING. 



Cooperation in water power and irrigation, J. H. Lewis (Pacific BuiMer 

 and Engin., 14 (1912), No. 12, pp. 246-248). — This is a paper presented before 

 the Development League Conference, at Lakeview, Oreg., in August, 1912. deal- 

 ing with the exercise of state credit in developing arid lands and water powers. 



It is claimed that most of the large commercial enteri)rises undertaken by
