AZOTUEIA 105 



Another atypical form of azoturia common in 

 country practice is that form affecting only one hind 

 limb. 



In these there is apparently acute pain ; the animal is 

 very uneasy, may lie down, and again rises to its feet 

 with considerable difficulty. There is marked fullness in 

 the gluteal region of the affected limb and trembling of 

 the muscles in the crural region. The limb does not seem 

 able to support its share of the bodily weight, and the 

 animal works itself into a state of extreme exhaustion in 

 its efforts to stand normally. While a goodly number of 

 these cases go down eventually, few of them succumb. A 

 few days of judicious handling restores the animal to 

 usefulness. 



A form of azoturia is often seen in country horses 

 affecting chiefly the front limbs. There is in these cases 

 immense tumefaction of the shoulder region, and the 

 brachial muscles. This swelling in many instances per- 

 sists for several days, although all other evidence of the 

 disease may disappear within a few hours after its 

 initiation. 



Of all the atypical forms of azoturia, the one which 

 causes the practitioner the most anxiety is that form in 

 which the predominating symptoms are of a nervous char- 

 acter. Although the animal is standing up and the usual i 

 azoturia symptoms are mild the horse appears to be suf- / 

 f ering from extremely heightened nervous tension. Con- 

 stant shifting about from one leg to the other is gone 

 through; the animal repeatedly backs up or attempts to 

 move forward ; the head is kept going from side to side, 

 or is jerked nervously upward and downward. In this 

 form there is frequently a degree of trismus, making it 

 almost impossible to administer medicaments orally. This 

 form of the disease frequently assumes a very serious 

 course. The constant moving about tends to aggravate
