PAT-HOLOGICAL CONDITIONS OF FEET.

and other contents of the abdomen had shot through, in the for- 

 ward ftill, and these filled up the chest and were immovable. Rup- 

 tures of the diaphragm of the horse have come under my notice on 

 several occasions, from 

 well-understood causes of 

 spasmodic kind, but the 

 above is the only case I 

 ever knew of a similar oc- 

 currence. 



The rest of the history 

 of the subject was soon 

 made out. The horse was 

 the property of a grocer, 

 who used to run him in a 

 light cart, and w^ho stated 

 that he had owned the 

 animal for about two years, 

 and that he had been a 

 reputed goc>d hunter, and 

 came to the last owner at 

 a loAV price through being 

 lame, in which state the 

 animal had continued, and 

 had worked till the ter- 

 mination now detailed; 

 thereafter I obtained both 

 fore limbs of the horse for 

 dissection, with the results 

 shown above. 



Figs. 710 and 711 repre- 

 sent component structures of the foot of a horse whose case was 



intimately and long known 

 to me. 



Fig. 710 shows the hoof 

 placed on a plane surface; 

 it is seen to be depressed 

 across the front of the wall, 

 and a light-colored streak, 

 marking an inveterate sand- 

 crack, extends from top to 

 bottom at the quarter. Cor- 

 responding to the hollow 

 depression of the foot above 

 referred to, there was nec- 

 essaril}' a bulging of the sole 

 downAvard, that is, a flat- 

 tening, and more or less 

 convexity at parts of the sole. Altogether a total abnormal state 

 is observable. The horn fibres are seen in the illustration of the 



Fig. 708.
