prostration, a hoarse, painful cough, a yellowish discharge from 

 nose and mouth, and great muscular weakness. The base of the 

 tongue, tonsils and soft palate are red and tumid with here and 

 there grayish or yellowish patches of false membranes. The 

 identification of swine plague may be made by the history of the 

 outbreak, the number of animals affected, the tendency to pul- 

 monary inflammation, the enlarged lymph glands, the presence of 

 the non-motile bacillus which does not generate gas in .saccharine 

 media, and which readily kills rabbits and Guinea-pigs with pure 

 cultures of the germ. 



Treatment will depend largely on the nature of the attack — 

 swine plague or- simple pseudomembranous infection. Isolation, 

 cleansing and disinfection will be demanded in both cases. In 

 swine plague all additional precautions to prevent its spread mu.st 

 be resorted to. In the simpler exudative inflammations the anti- 

 septic local treatment and general febrifuge measures will be 

 demanded. 



PSEUDOMEMBRANOUS PHARYNGITIS IN DOGS. 



Relation to diphtheria in man and horse. Symptoms ; fever, prostration ; 

 swollen throat ; cough ; vomiting ; false membranes on fauces and tonsils ; 

 cyanosis. Treatment : local antisepsis ; febrifuges. 



Rossi and Nicholski claim that dogs contract diphtheria by 

 sw^allowing the excrements of diphtheritic infants, but these 

 observations lack confirmation, and the infrequency of such an 

 occurrence argues again,st it. Robertson records cases of canine 

 angina with false membranes occurring at the same time as a 

 .similar affection in the hor.se. The victims were puppies and the 

 mortality was high. Exact observations are, however lacking. 



Tlie symptoms were dullness, prostration, anorexia, a hard, 

 cough, swollen throat, vomiting, diarrhoea, and the presence of 

 grayish or yellowish false membranes on the fauces and tonsils. 

 The breathing was difficult and painful and the mucosae cyanotic. 



Treatment has been es.sentially local, consisting of swabbing 

 with solution of boric acid (1:200), chlorate of potassa, perchlo- 

 ride of iron, or nitrate of silver.
