within the integuments, and occasion tumefaction of a toe : this 

 must be remedied by sawing away the indenting portion. See 

 Cutting of Claws in Operations. — A tumefied toe or toes we oc- 

 casionally meet with, where around the base of the claw the secre- 

 tory part or quick is swollen, inflamed, and excoriated. This is a 

 mangy afl^ection, and is described with the anomalies of Mange. 



HERNIAL TUMOURS. 



As the dog may be the subject of most of the varieties of hernia, 

 so these tumours may be various ; but that to which he is naturally 

 most prone is epiplocele, and which tumour is by no means un- 

 common in such as are very fat : the unclosed state of the abdo- 

 minal ring, and the very great dimensions of the omentum^ par- 

 ticularly when enlarged by an extraordinary quantity of adipose 

 matter, and pressed on by other accumulations, as may be supposed, 

 very naturally incline it to be gradually pressed through the ring, 

 and to occupy the scrotal bag, where I have seen the distention 

 enormous. I never saw a case of strangulation ; but if such were 

 to occur, without doubt, it would shew itself by the distention and 

 colicliy pains. The operation of the taxis must be first attempted; 

 and, should that fail, proceed to dilate the stricture by which it is 

 strangulated.

 ness, or otherwise the bloodvessels of the opaque cornea are seen
