The Ailments of Horses, 39 



The organ is pale in colour, soft, and 

 flabby, with a greasy feel. 



Here and there a fatty patch will be 

 seen ; less frequently one side of the 

 organ is affected. A fatty patch on the 

 right side predisposes to sudden death 

 through rupture of the organ, fatty tissue 

 being incapable of fulfilling the duties 

 assigned to the muscular tissue composing 

 the heart, which has been " replaced " 

 by the fatty material. The liver may 

 suffer the same change. 



Heart, fatty infiltration of. — The 

 heart may be entirely embedded in fat, 

 and yet quite healthy so far as its intimate 

 structure is concerned. 



Very fat animals have often their heart 

 in this condition. 



So long as the deposit of- fat does not 

 interfere with the movements of the 

 organ, there need be no fear of harm. 



The oily material is simply poured in 

 between the fibres (does not replace 

 them). 



Heart, dropsy of. See Dropsy 



Hock, capped. — In ordinary parlance, 

 this means any swelling situated upon the 

 point of the hock, forming, as it w^ere, 

 a cap over this. 



Playing over the point of the hock 

 there is a flexor tendon {flexor jjedis 

 perforatus), the expansion of which forms 

 a cap. 



Now, between the tendon and the bone 

 there is a lubricating membrane, while 

 between the former and the skin there is 

 a similar apparatus.
