RHEUMATISM. 51I 



three pure-bred animals affected with chorea, a disease whose nature is 

 still undetermined, but which certainly shows all the characters of 

 chronic myelitis of toxi-infectious origin. It did not produce any 

 appreciable result. At the present time we have in hospital a two-year- 

 old thoroughbred dog affected with this disease, which we have unsuc- 

 cessfully treated for the past three months with subcutaneous injections 

 of cerebral substance and intra- venous injections of iodine. 



RHEUMATISM. 



igg. A ten-year-old Danish dog, brought for examination September 

 30th, 1894. 



For several years this dog had shown repeated symptoms of 

 muscular rheumatism — difficulty in moving, stiffness of the neck, back, 

 and lim.bs. At certain times it suffered such pain as to howl loudly, 

 especially at night, or when it rose after having remained long in one 

 position. It was in the habit of bathing in a running stream near its 

 owner's house, and the attacks frequently followed these baths. 



Except for these rheumatic attacks the dog had enjoyed fairly good 

 health. Five or six days before, more serious troubles, however, had 

 been noted. The animal refused food, remained continually lying down, 

 and had frequent attacks of dry cough. If forced to walk, it rolled 

 from side to side, and ended by falling. These troubles continued, 

 though in less degree than at first. 



When the animal was brought here it showed stiffness in movement, 

 especially of the head and neck ; the neck was tense and rigid, and 

 seemed painful even on slight pressure. The heart revealed a double 

 systolic and diastolic murmur. 



We prescribed general h3'gienic treatment, together with internal 

 administration of i^ drachms of sodium bicarbonate and 15 grains of 

 sodium salicylate. During the night and next day the condition 

 remained stationary. 



On the 2nd October the patient was found dead in its kennel. 

 The owner sent the body to the school ior post-tnorteni examination. 



Autopsy. — No liquid in the abdominal cavity ; intestines of normal 

 aspect ; gastro-intestinal mucous membrane slightly hyperaemic at 

 points ; liver enormous and blackish, with the appearances of " cardiac " 

 liver ; the spleen exhibited several blackish swellings, the largest the 

 size of a nut ; both kidneys were reddish, and their surface was 

 marbled ; sections showed lesions of chronic nephritis. 



The right testicle was the size of a hen's egg, and contained a 

 tumour ; the spermatic cord and the sublumbar lymphatic glands were 

 invaded. 



The lungs contained numerous little whitish cancerous patches. 

 The pericardium was normal. The heart was very large, marbled with 

 greyish irregular patches, indicating areas of indurative myocarditis. 

 The left heart showed lesions of chronic endocarditis ; the mitral valves 

 were thickened, contracted, fibrous at their base, reddish and vege- 

 tating towards their free margins ; the aortic valves were thickened and 

 contracted. The right heart was less changed, though the ventricle
