piece of catgut tied tightly around the 

 base of the polypus. The nostrils are

Malignant tumours are such as have a 

 tendency to return after being excised. 

 Under these circumstances, the excision 

 of the tumour demands' giving it a wide

Abscesses must, when ripe, be opened. 

 If preferred, an abscess may be allowed to 

 rupture. It is better to open it. 



U 



Urine, incontinence of.— By this we 

 mean inability to retain the urine within 

 the bladder, either through paralysis of 

 the latter, disease of its walls, or irrita- 

 bility of its lining membrane. 



Foals commonly are found to be pass- 

 ing urine through their navel opening. 

 This is caused through a tube leading 

 from the bladder not having become 

 closed (which it ought to do before birth), 

 in this way allowing the escape of the urine. 



Treatment. — For the incontinence of 

 adult animals, we must try and get to 

 the root of the cause, then treat in 

 accordance with this. 



A ball composed of half a drachm 

 of powdered nux vomica and 4 drachms of 

 powdered gentian, with 2 drachms of 

 linseed meal and treacle, given twice 

 daily, will be found useful.
