histological exauiinatioii of 35 cases of kiduey affections other than pyelone- 

 ;)hritis. 



The anthor divides the cases on the basis of his findings into acnte nonpuru- 

 lent and metastatic purulent nej)hritis. The first group is again subdivided 

 into glomerular nephritis, the acute with small celled infiltrations, ])arenchy- 

 uia'ous, and hemorrhagic. Further classifications which are given are those 

 with edema and chronic indurative nephritis. 



Contributions to our knowledge of immunization against swine plague, 

 11. E. E. Beoll {Bcitrdgc zur linmunisicning gcyvn Schwcincscuche. Inaug. 

 Diss. Univ. Bern, 1908, pp. 2Ii). — This work has to do with investigations of 

 various methods which have been proposed for immunizing against swine plague. 



From the results with young pigs it is noted that the preliminary intra- 

 abdominal injection of killed bacteria and the subsequent injection of living 

 bacteria (according to Beck and Koske's method) predisposes to swine plague 

 and does this before immunity can be attained. Intra-abdominal injections of 

 killed bird bacteria and the preliminary treatment with living bacteria did not 

 yield good results. A high degree of immunity was obtained against animals 

 artificially infected by vaccinating with bacteria which had been heated for 20 

 hours at from 52 to 55° C. Autolysates as used by Titze and according to Con- 

 radi's method are not regarded as practical on account of their great degree of 

 toxicity. The best results were obtained against artificially infected animals 

 with extracts which were not filtered and which were obtained by centrifuging 

 and subsequent sterilization with oil of mustard. 



Experiments in regard to immunizing against swine plague, R. Bassenge 

 (Ztsclir. E.rpt. Path. u. Thrr., 6 {1!>0!)), No. S, pp. 689-G9.'i; abs. in Biochem. 

 ZentU., 9 (1909), No. 7-8, pp. 362). — The author produces a glycerin paste from 

 substances obtained from bouillon cultures of the Bacillus suiseptictis by the aid 

 of agglutination, centrifuging, and shaking out, which is capable of producing 

 immune bodies. From the tests it appears that mice can be jirotected even 

 after 3 weeks against superseding infection with the bacilli. 



A contribution to the study of chronic bronchitis in the horse, F, GRiiXEB 

 (Sclitccis. Arch. TicrhciUc. .31 (1909). No. 6, pp. 351 -.395 ; ah.s. in Vet. Rec, 22 

 {1910), No. ll-'fO, pp. 139, 1-iO). — The author describes a sjieeial form of equine 

 chronic bronchitis, provisionallj- designated as dry bronchitis, which he has 

 repeatedly observed and studied, and the symptomology of which he especially 

 contrasts with that of broken wind. 



A bibliography of 69 titles is appended to the account. 



Investigations of the number of erythrocytes and of the amount of hemo- 

 globin in the blood of horses suffering from rheumatic hemoglobinemia in 

 comparison with healthy horses and those suffering from other internal 

 diseases, Konig {ilonatsh. I'raht. TicrhciUc, 21 (1909), No. 1-2, pp. l-o-i; ab.s. 

 in Rev. Gen. Med. V6t., 15 {1910), No. 112, pp. 211, 218).— The average number 

 of erythrocytes found in healthy horses was 8,323,000 per cubic millimeter; in 

 stallions 9,434,000 were found, in geldings 8,179,000, and in mares 7,357,000. 

 The amount of hemoglobin in the blood of healthy horses varied from 95 to 

 105 per cent of normal. In rheumatic hemoglobinemia as a rule the normal 

 number of ei'ythrocytes was found but in every case investigated the amount 

 of hemoglobin increased from the onset. Never in this affection was a diminu- 

 tion in the number of erythrocytes observed. This is considered proof that 

 the increase in the amount of hemoglobin is not due to the disintegration of 

 erythrocytes and a confirmation of Frohner's theory that it is due to the 

 passage into the blood of coloring matter from affected muscles. 



In some internal diseases of the horse, as in different kinds of colics (33 

 cases), gastroenteritis (7 cases), gangrenous pneumonia (6 cases), tetanus (5
