CASE OF SPASM OF THE DIAPHRAGM.

Attachment. —Superiorly, to the postero-external part of the 
head of the tibia: inferiorly, it becomes inseparably united with 
the tendon of the flexor pedis, about one-third of the length of 
the cannon downwards. 
Relations .—Posteriorly, with the gastrocnemii; anteriorly, 
w ith the body of the til ia, and the posterior tibial artery and 
vein. Superiorly and internally, with the popliteus; inferiorly 
and externally, with the flexor pedis. 
Structure .—Superior attachment, fleshy and tendinous; after¬ 
wards entirely fleshy, and so it continues until it ends in a tendon 
which issues from its very centre. Its fleshy belly crosses ob¬ 
liquely over to the inner part of the leg, w here it terminates, mid¬ 
way between the stifle and hock, in its cordiform tendon, which 
passes through a theca at the inner side of the hock. Opposite to 
the head of the great metatarsal bone it runs in the same sheath 
with the tendon of the flexor pedis, with which it ultimately forms 
one common tendon. 
Action .—It operates as a coadjutor to the flexor pedis.

“ Press not the generous steed too far.*’ 
Nimrod, in one of his excellent papers “ On the Condition of 
Hunters,” which he published in the Sporting Magazine §ome 
years since, is the first, as far as I know, who has called the 
attention of horsemen to this point. I am not aw are of its being 
noticed by any writer, veterinary or other, before him. “When 
a horse,” he says, “ is much exhausted after a long run with 
hounds, a noise is sometimes heard to proceed from his inside, 
which is erroneously supposed to-be the beating of the heart; 
whereas it proceeds from the excessive motion of the abdominal 
muscles.” ( Sport . Mag . vol. xiv, N. S. page 329).
