 less lameness.

Founder, or inflammation of the feet, called by veterinarians laminitis, 

 consists in fever, inflammation of the sensitive parts of the foot, including 

 the laminee, and of the foot bone, but is most severe in the forward por- 

 tion, where greatest strain occurs when standing. Acute inflammation of 

 the foot, or founder, differs but little in its physical manifestations from 

 other inflammatory symptoms, except that it seems more complete and 

 permanent. Acute founder is generally produced by overwork or over- 

 heating and exhaustion and sudden cooling, while the sub-acute form 

 may be the result of diseases of the respiratory organs, suddenly leaving 

 those parts and manifesting itself in the extremities. 



Causes. — The disease may be brought about directly from hard work 

 on dry, solid roads, and consequent strain on the laminae (scale of the 

 bones), from over-feeding or drinking cold water when warm, especially 

 when the predisposing cause already exists. So it may be brought about 

 by other diseases, as inflammation of the lungs. Heavy, fat horses are 

 especially predisposed to founder, and so are those ^ith small and de- 

 formed or large, flat feet. 



ACUTE FEVER IJf THE FEET. 



How to know it. — There will be general fever and stiffness, and sore- 

 ness ; there may or may not be shivering. Soon extreme tenderness of 

 the feet follows, generally most severe in the forward part, but soon m 

 the heel ; the pulse is strong, full and rapid ; the breathing quickened.
