I. Blood Spavin. 



This may be defined as a distension, or enlargement (dilatation) of the 

 veins of the hock joint, and overlying the seat of bone and bog spavin ; 

 a local venous congestion, caused generally by swelling, impeding the 

 flow of the blood, and often connected with bog or bone spavin. It is 

 harmless ; in fact it may be considered as accompanying, or the result of 

 other disease of the joint. 



What to do. — In the early stage cold water perseveringly applied, fol- 

 lowed by cooling lotions, equal parts of alcohol and rain water, or one 

 pint of brandy to one-half pint of water, applied as a lotion. If this 

 does not relieve the diflSculty, use a strong infusion of bayberry bark, 

 using considerable friction by hand rubbing with either of the remedies 

 named. 



n. Bog Spavin. 



Common bog spavin is technically (as is windgall) an enlargement of 

 the Bursa Mucosa, just as a distension of the sub-cutaneous (beneath the 

 skin) veins in the region of the hock is called blood spavin. These cause 

 an undue secretion of joint oil and a dropsical effusion into the joint, 

 producing swelling'having all the character of inflammation of the true 

 hock joint. This inflammation of the upper or principal hock joint is 

 true bog spavin.
