Pyemia. Arthritis. Abscesses of the Ductless Glands 611 



The outlook for recovery from pyemic arthritis is very 

 poor. Potassium iodide internally has given apparently 

 good results in some of my cases, but it must be used with 

 great caution because of the high susceptibility of cattle to 

 iodine. If pus forms and samples can be aspirated for cul- 

 tures, autogenous vaccines are worthy of trial. Locally 

 little can be accomplished. The inflamed articulation may 

 be fomented or blisters may be applied. Should the presence 

 of pus be positively diagnosed, it may be aspirated and the 

 cavity refilled with 20 per cent. Lugol's solution in water or 

 glycerine. If an abscess forms, it should be opened freely 

 and the cavity packed with gauze saturated with tincture 

 of iodine mixed with glycerine, or with some other suitable 

 disinfectant. Movement of the joint should be restrained in 

 any manner available. 



The uterine cavity, if still an active center of infection, 

 should receive proper attention. The general care 01 the 

 animal should be of the best. 



Abscesses of the liver and other glands are occasionally ob- 

 served during or subsequent to severe uterine infection. 

 The clinical symptoms of such abcesses are vague and gen- 

 erally fail to afford secure ground for diagnosis. The domi- 

 nant symptom generally is that of ill health with gradual 

 emaciation. Should the abscess rupture externally, as some- 

 times occurs when located in the liver or kidney, diagnosis 

 may be possible. The alert practitioner should always sus- 

 pect pyemic disturbances when ill health follows the termi- 

 nation of pregnancy, and should make the most careful 

 search possible for pyemic abscesses. In such cases labora- 

 tory examination of the blood is highly important and should 

 not be neglected. 



H. Cystic Degeneration of the Uterine Walls 



with Hydrometra. 



Hydrometra, or distension of the uterus with liquid, is not 



common and is dependent upon a variety of causes. It has 



already been noted that mucus and menstrual debris may be 



retained in and distend the uterus when the cervical canal
