The natural colour of the nasal mucous membrane 

 is a delicate pink. 



Sometimes morbid growths appear within the 

 nasal passages, and these are occasional causes 

 of defective breathing, such as roaring. 



The Glands below the ear and beneath the branches 

 of the lower jaw ought to be manipulated, in order 

 to ascertain whether there is any enlargement of 

 them. 



The Withers. — Bruises and fistula are the only 

 injuries hkely to be encountered in this region. 



The Shoulders should be inspected for wasting 

 of the muscles (shoulder-slip), and for injuries to 

 the skin, the result of bruising by the collar. 



The Elbow ought to be examined for capped- 

 elbow, and for a scar on the inner side as evidence 

 — ^by no means positive, but suggestive — of the 

 animal having been unnerved. 



Inspect the Knees for blemishes, for stiffness, 

 and for bursal enlargements, thickening of the 

 skin, etc.
