290 DISEASES OF THE BONES AND ARTICULATIONS. 



tism in the masseters (a great difficulty in mastication). Only in 

 very severe cases is any fever noticed. 



The course of the disease is sometimes acute and occasionally 

 . chronic. In the former case the disease runs its course very 

 quickly, and may disappear without any special treatment, but 

 there is always a tendency to relapse. In the latter form the disease 

 may be prolonged for- months, varying in degrees of intensity, also 

 showing a tendency for the pain to move from one part of the body 

 to another. This peculiarity is noticeable in chronic rheumatic 

 conditions. 



Therapeutics. The agents recommended for the dog are sali- 

 cylic acid, antipyrine, tincture of colchici, morphia, friction, mas- 

 sage, and electricity. The first three drugs produce the most 

 favorable results: 



R. — Salicylic acid 5.0 



Aqua destillata 50.0 



S. — Oae tablespoonful three times daily. 



R. — Antipyrine 5.0 



Syrup, simplex . 25.0

 to the massage than to anything else. It is advisable to rub the

 may be greatly improved by putting the patient into a bath of 

 28°, rubbing it dry and wrapping it in hot blankets. (Fig. 63.) 

 The opinion concerning electricity is much divided. The author 

 has never been able to obtain any very marked results by using 

 this form of treatment. 



Muscular rheumatism in some cases may be confounded with 

 those of cysticercus cellulosus. In the latter case parasites should
