220 DISEASES OF THE HOESE. 



discover its origin, or secure to it a satisfactory resurreotioa 

 It applies, however, when used by horsemen, to a falling 

 away or shrinkage of the muscles of the shoulder, and 

 indicates not so much a lameness in the shoulder as it does 

 a disease elsewhere — in the foot or leg, as corns and disease 

 of the pastern joint. Atrophy should be substituted for 

 sweenie, as it is generally sympathetic, and, moreover, 

 means that the body or a part is diminishing in bulk. 



Treatment. Remove the cause of atrophy or sweenie, 

 and the effects will pass away. 



Sympathy. — That condition which is developed in one 

 part of the system or body of an animal, although not of 

 itself a disease, but is the result of disease or accident 

 happening to some other, or remote portion of the body. 

 This sympathy is communicated through and by the 

 nervous system. A nail in the foot, or a broken bone, is 

 immediately followed by sympathetic fever, and general 

 disturbance of the whole system. Herein lies the great 

 difference between animal and vegetable life. A branch of 

 a bush or a tree can be lopped off without any disturbance 

 to the life or health of the main trunk. No such immu- 

 nity exists in the animal creation. 



Synovia. — A clear, colorless and viscid fluid, secreted 

 by the lining membrane of the joints, for the purpose of 

 preventing friction, and allowing an easy motion of the 

 heads of the bones over one another. Synovia sometimes 

 changes in quality, becomes thinner, and gives rise to 

 swellings of the joints. (See Blood and Bog Spavin.) 



Synchronous. — This name is applied to the action or 

 beat of the heart, when it is in time with the beat or 

 pulsation of an artery.
