1186 EXPERIMENT STATION RECORD. 



It was found that the glanders bacillus may be so modified in virulence as to 

 produce lesions widely different in tlieir histological features. The most viru- 

 lent cultures produce primary necrosis of the tissue followed by an invasion of 

 polymorphonuclear leucocytes. Glanders bacilli of moderate virulence give a 

 primary lesion of an acute inflammatory nature without necrosis. Attenuated 

 bacilli produce proliferation with the formation of giant cells. Numerous grada- 

 tions occur between the lesions of acute exudative and chronic proliferative 

 glanders. The glanderous lesion is always focal in character. 



A simplified method of diagnosing glanders by agglutination, W. E. King 

 and E. M. Houghton (Aincr. Vet. Rcr., 31 {1007), No. 2, pi). 178-190, figs. 2).— 

 In the opinion of the authors, the chief advantages of the agglutination method 

 for diagnosing glanders are its reliability, convenience, and the possibility of 

 using it for confirming diagnosis after the death of the animal. The apparatus 

 necessary for carrying on the test is described and various details connected 

 with the laboratory work are discussed. If four agglutination tubes are used 

 and negative results are olttained in all these tubes, this may be considered as 

 positive proof that the animal is not affected with glanders. Similarly if a I'e- 

 action is obtained only in a tube in which the serum is diluted 200 times, the 

 diagnosis of glanders is not indicated. If agglutination takes place at dilutions 

 of 200 and 500 but not at 800 and 1,200, the case may be considered doubtful. 



Skin and eye reaction to mallein, A. Putzeys and T. Stiennon (Ann. MM. 

 Vet., 56 {1907), No. 11, pp. 616-619).— A test was made of these methods of 

 obtaining a reaction in glandered horses. For this purpose the authors experi- 

 mented with 2 horses and came to the conclusion that the skin and eye reaction 

 to mallein is of no ]iractical importan('(> for the reason that it is too inconstant. 



Interpretation of the reaction to mallein, II. Racca {VI in. Vet. [Milan], Sez. 

 Prat., 30 {1907), Nos. 32, pp. 517-526; 33, pp. 5',0-5Ji2; 3-'i, pp. 55.',-558; 35, pp. 

 570-573; 36, pp. 585-590; 37, pp. 598-603).— A critical review is presented of the 

 literature relating to the use of mallein with particular reference to the inter- 

 pretation of the reaction of glandered horses. 



The horse: Its treatment in health and disease, edited by J. W. Axe {Lon- 

 don [1907], Vol. 8, pp. XII+189-J,12, j)ls. /,}, flr/.s. .9//).— In this, the eighth vol- 

 ume of the general treatise on the horse, prepared under the author's direction, 

 breeding, training, stables, examination of horses as to soundness, and related 

 topics are taken up. 



The pathological changes in the eggs and oviducts of birds, S. P. von 

 DuRSKi {InaiKj. Diss. I'nir. Bern, 1907, pp. 35, pis. 3). — Descriptions are given 

 of the anatomical characters of various sorts of abnormal eggs. The patholog- 

 ical anatomy and physiology of the oviducts are also discussed with particular 

 reference to the connection between these pathological conditions and the pro- 

 duction of abnormal eggs. 



The histology of fowl plague, J. Schiffmann {Vcnthl. Bakt. [etc.], 1. Aht., 

 Orig., 1/5 {1907), No. 5, pp. 393-'i03, pi. 1). — A number of inoculation experi- 

 ments with the virus of fowl nlague were made, particularly in geese. In the 

 cerebrum of artificially inoculated geese certain corpuscles were found which in 

 some respects resembled Negri bodies, but could be distinguished from them 

 by the fact that the Negri bodies may occur in large numbers in a single cell, 

 while the corpuscles of fowl plague occur singly in each cell. These specific 

 bodies were found only in inoculated birds and never in healthy geese. Ne- 

 crotic ai'eas were also noted as the characteristic lesions of the disease. 



Epithelioma contagiosum, A. T. Kinsley {Ainer. Vet. Rev., 30 {1907), No. 

 12, pp. 11/38-1 f/liS, figs. Jf). — Notes are given on the occurrence of this disease 

 and on the pathological histology observed in the characteristic lesions. It is 

 difficult to differentiate between this disease and roup and the two may be
