Bacterium, pyogenes associated with, a case of multiple arthritis in a hog, 

 A. R. Wabd ^Abs. in Jour. Bad., 1 (1916), No. 1, p. 114). — It is pointed out that 

 polyarthritis of swine is frequently encountered in post-mortem inspection of 

 meat. B. pyogenes was isolated in pure culture from a case showing various 

 stages of articular involvement from the early stages of synovitis to later stages 

 showing erosion of articular cartilage, exostosis, and anchylosis of the joints. 



Swine erysipelas and hog cholera, A. A. Feekeiba {Doengas Ruhras dos 

 Suinos e a Peste Suina. Lisbon: Assoc. Cent. Agr. Portuguesa, 1915, pp. 32, 

 figs. 6). — This pamphlet briefly enumerates common and rare contagious dis- 

 eases of swine in Portugal and briefly discusses swine erysipelas. Hog cholera 

 in regard to its prevalence, morbidity, diagnosis, infectivity, and immunization 

 (simple or simultaneous vaccination) is also discussed. 



Agglutinins in hog-cholera immune serum for Bacillus suipestifer, H. 

 Wehrbein (Jour. Infect. Diseases, 19 {1916), No. 3, pp. 446-451). — ^Tabular 

 data of the agglutinins for B. suipestifer in 100 hog-cholera immune sera, in the 

 sera of 8 normal pigs, and in 8 sera of virus pigs are submitted. An experi- 

 ment to ascertain the connection between the agglutinin titer for B. suipestifer 

 and the antibodies in a hyperimmune serum is also reported. 



Further studies on the virulent salt solution used in the production of 

 hog-cholera serum, W. S. Robbins {Jour. Infect. Diseases, 19 {1916), No. 5, 

 pp. 708-711). — Experimental data reported indicate that "virulent salt solu- 

 tion is not nearly so virulent as virulent blood, and that while it is efficient in 

 hyperimmunizing by the subcutaneous method it would no doubt be imprac- 

 tical in the intravenous method because of the difficulty of injecting enough 

 of it intravenously to produce very potent serum. Even if it is used in mix- 

 ture with virulent blood the amount of the mixture required to produce good 

 serum would be unusually high."

Lameness of the horse, J. V. Lacroix {Chicago: Amer. Jour. Vet. Med., 1916, 

 pp. 271, figs. 62). — The first section (pp. 15-35) of this work deals with the eti- 

 ology and occurrence of lameness ; the second section (pp. 87-58) with diagnostic 

 principles; the third section (pp. 55-188) with lameness in the fore leg; and 

 section four (pp. 185-261) with lameness in the hind leg. 



The effect on horses of feed heavily inoculated with Bacillus coli isolated 

 from oat hay, R. Graham and L. R. Himmelberger {Abs. in Jour. Bad., 1 

 {1916), No. 1, pp. 115, 116). — Studies reported by Rogers, Clark, and Evans 

 (E. S. R., 88, p. 631) on the occurrence of the colon bacteria on grains led the 

 authors to conduct investigations with a view to discovering a type pathogenic 

 or virulent for live stock (see E. S. R., 84, p. 681). 



" In no case were we able to produce death by feeding, but the condition 

 in the experimental horses was such as to suggest that feeds contaminated 

 extensively with colon bacilli lower animal vitality and render the animal 

 more susceptible to other injury. ... It is evident from these observations 

 that the occurrence of B. coli as isolated from grain which was the causative 

 factor of so-called ' forage poisoning ' bears no primary relation to the disease 

 resulting from the feeding of the oats, but from a sanitary standpoint it seems 

 advisable to protect animal feeds from B. coli contamination in so far as 

 possible." 



Sclerostome parasites of the horse in England, I, C L. Boulenger {Parasi- 

 tology, 8 {1916), No. 4, pp. 420-439, pi. 1, figs. 7).— This first part deals with 

 three species of the genus Triodontophorus. of which two are described as new 

 to science, and one species of the genus Oesophagodontus. A bibliography of 

 19 titles is included.
