CHAPTER VI. 



DISEASES OF THE LYMPHATIC SYSTEM. 



Diseases of the lymphatics are numerous, highly important, and 

 still imperfectly understood. They follow various accidents, local 

 inflammations, certain specific diseases, such as tuherculosis, and may 

 occur in an isolated form without involving any other part of the body.

Inflammation, usually of infectious origin, may attack lymphatic 

 vessels (lymphangitis) or lymphatic glands (adenitis), giving rise either 

 to simple lymphangitis, suppurative lymphangitis, or again to simple 

 or suppurative adenitis. 



It is unnecessary to emphasise this point in general surgical pathology, 

 for it is identical with that which is observed in other domestic animals, 

 but in order properly to detect the glandular symptoms in certain
