HORSES: THEIR POINTS AND MANAGEMeNT 



Ircidment. — In ai-utc iiillaiiiiiiatioii, apply a cooling lotion, 

 such as tincture of arnica, and tincture of opium, of each two 

 ounces, added to a pint of water (cold). If the ca])sular lij^a- 

 ment of the joint has been punctured, treat as in open joint 

 (which see\ Give a mild dose of physic, but do not purge the 

 horse. If the animal has rheumatism, treat as in this disease 

 (see this.) Permanent enlargement of the hock is practically 

 incurable (see spavin, rheumatism, open joint, strangles, 

 etc.). 



THORO-PIN OF HOCK. 



This means a swelling, or more correctly, a distension, 

 at the upper and back part of the hock. The contents of sw^ell- 

 ing consists of a liquid, so that by pressing the tips of the 

 fingers against the former, the liquid is forced through (either 

 to the outer or inner side), accordingly causing the swelling to 

 bulge on the opposite side, hence the name, thorough pin ; 

 derived from through pin. 



It is the capsular ligament of the so-called true hock 

 joint which becomes distended in this disease, and voung horses 

 with upright hocks are said to be most subject to it, though it 

 dees occur in older animals. 



Symptoms. — Absence of inflammation and lameness, but a 

 fluctuating swelling, or distension, at the upper and back part 

 of the hock, capable of being distended from either side on 

 pressure with the Angers. It is only in rare instances that 

 lameness is present, and not until the animal has undergone 

 severe exertion. Blistering will reduce the swelling a little, 

 though it is hardly likely to remoxe it. If preferred apply 

 cold water spray for about ten minutes every night, and paint
