 sive agents applied to the part. The neck may be held rigidly in 

 one position, to one side or elevated so that there is great difficulty 

 in getting the nose to the ground. 



The costal muscles are less frequently attacked (pleurodynia), 

 but the same general principles guide in diagnosis. 



Seidamgrotzky alleges the constant existence of acidity of the 

 urine in muscular rheumatism. This may be attributed to the 

 active trophic changes going on in the muscles. 



SYMPTOMS OF ACUTE ARTICUI^AR RHEUMATISM 

 IN CATTlvE. 



Sudden onset, hyperthermia, chill, fever, acid saliva, decubitus, does not 

 stretch on rising, lameness, joints involved, metastasis, variability, morning 

 and noon, suppuration, walking on toe, secondary articular rheumatism. 

 Course : muscular symptoms, cardiac, pleuritic, digestive. Chronic. Mus-

 staring coat, cold horns and ears, dry muzzle, impaired appetite
