survive it. The hoof may not separate entirely, and the coffin- 

 bone, only being partially supported, descends and rests on the 

 sole, producing what is called a pumiced foot. 



That variety of founder called chest-founder is characterized 

 by all the general symptoms of the disease as above described. 

 But the principal seat of the inflammation is the muscles of the 

 breast and chest, which will be found hot, tender, and swollen. 

 There will be great lameness, pain, and stiifness in moving. 

 After the inflammation has subsided, or becomes more of a 

 chronic form, a great wasting away of the muscles of the chest, 

 particularly of those about the breast, will occur, giving the 

 horse an unnatural, ugly hoUowness about the breast. 



Body-founder is much of the same character as chest-founder; 

 the chief difference being, that the tenderness and inflamma- 

 tion of the muscles, as well as the lameness, are more general. 



A peculiar characteristic is its migratory (moving) character, 

 or disposition to change from one place to another. It may 

 suddenly leave the body and locate in the feet, or go from the 

 feet to the lungs, or heart or pleura ; and when thus setting on 

 the heart, is quite certain to prove fatal. It is this migratory 

 character of the disease, the tissues or parts which it attacks, 

 the general train of its symptoms, and the causes which are 

 known to produce it, that establish its character as rheumatism. 



It requires some care to distinguish founder from some other 

 diseases. I will present a few of the distinguishing symptoms. 

 It is, perhaps, most likely to be confounded with lung fever. 



In lung fever the limbs are cold ; in founder, hot. In lung fe- 

 ver, can not drink ; in founder, no difficulty in drinking. In lung 

 fever, can not lie down, but stands still ; in founder, keeps con- 

 stantly moving when standing, and lies down or drops, and con- 

 tinues lying, early in the disease. In lung fever, certain peculiar 

 sounds in the lungs ; in founder, only the natural ones, slightly 

 increased by the general fever present. 



The quietness of the horse when lying down will distinguish 

 founder from colic or inflammation of the bowels, in which he
