PAROTITIS. 599 



abscess in the gland-structure ; at other times slow in its pro- 

 gress, affecting only limited portions of structure, and, after 

 a tedious course, issuing in the production of several distinct 

 and circumscribed collections of pus. 



Sjrmptoins. — Those which specially indicate the onset of the 

 inflammatory action are rather insidious, not diagnostic, and 

 of slow development. The horse exhibits a disposition to pro- 

 trude his nose, with a disinclination to move, or difficulty in 

 turning the head independent of the body. There is pain on 

 manipulation of the throat, with a steady swelling of the 

 parotid structure. 



This, whenever estabHshed, does not necessarily proceed to 

 suppuration, cases often being observed where congestion and 

 tumefaction proceed to a considerable length, and after some 

 days suffer subsidence. When terminating in pus-formation, 

 the skin over one or more points becomes tense, thin, disposed 

 to part with its hair, and inclined to exude a little serous fluid. 

 When not evacuated, or discharging itself externally, the 

 matter may find escape into the pharyngeal pouch, showing 

 itself at the nasal openings. 



Treatment. — This consists at first m steady fomentation, 

 with poulticing; while, should the process seem lagging, 

 good will often follow the employment of a smart cantharides 

 liniment, or daily application of common iodine ointment. 

 When the abscess seems matured, a careful incision ought to 

 be made, so as to allow a free escape of the matter. Following- 

 its discharge, nothing is needed save attention to cleanliness. 

 If weakness is a marked feature, the horse will require, with 

 good food, some tonic, such as sulphate of iron, either alone or 

 in combination with a vegetable bitter. Should any indura- 

 tion remain after recovery, the use, both locally and internally, 

 of some preparation of iodine is indicated. 



V. Salivation, or Ptyalism. 



The condition of the presence in the mouth, and of the dis- 

 charge from it, of an extra amount of sahva i&not unfrequently 

 observed in the horse, and although not a serious may be a 

 troublesome affection. 



This annoying symptom of several very different conditions 

 may occur either from an extra secretion of saliva or from an
