 giving rise to hsBmorrhagic discharges, petechise, and 

 ecchymoses. It is seldom so important as to necessitate 

 those measures suggested for internal haemorrhage. 



Section 4. — Op the Venous System. 



This set of blood-vessels in the ox is remarkable for

 capacity. 



Phlebitis. — Inflammation of a vein sometimes takes
