296 THE STOCK owner's ADVISEE. 



VARICOSE VEINS 



Are seldom seen in the lower animals. I have seen the condition 

 in horses and cattle. The treatment is pressure to the parts. If 

 an abscess should form, it should be opened and a blister applied. 

 The cantharides blister is the best in this ease. 



VEIN STONES. 



Concretions have been seen in dilated veins of the neck and 

 other parts. 



ENTRANCE OF AIR INTO VEINS. 



Air rapidly injected into the veins causes immediate death. 

 The animal is suddenly seized with symptoms of faintness and 

 convulsive breathing; falls and perhaps immediately dies. If 

 only a small quantity enters the vein the animal may rally. 

 This subject has been carefully investigated, and it behooves the 

 operator to be careful when bleeding. 



INFLAMMATION OF THE ARTERIES. 



This is a rare aifection in the lower animals, but is occasionally 

 seen. Inflammation of the artery is caused by an injury. Exu- 

 dation from the walls of the inflamed vessels form a clot, com- 

 posed of lymph and coagulated blood, which plugs the artery. 

 The symptoms of plugging of the external iliacs are coldness of 

 the extremities, with muscular debility, which increases with 

 exercise. The diagnostic sign is absence of pulsation in the 

 artery, detectible by examination per rectum. The animal suf- 

 fers great pain, the limb is deathly cold, and perspiration breaks 

 out over the body. He may suddenly recover and appear all 

 right, but may be affected again at any time. If the circulation 

 is completely cut off, death will take place. 



Treatment. — Apply hot fomentations to the parts. Hot lini- 

 ment may be applied with smart friction. If the limb remains 

 cold after this treatment has been employed, it may be ascer-
