CASE OF DIFFICULT PARTURITION IN A MARE. 327 
the post-mortem examination, I did not see the viscera until 
they had been removed from the body, and the lungs I did 
not see at all. Upon a very careful examination of the feet 
and legs, nothing whatever could be found to account for the 
lameness. The feet were perfectly healthy, and although 
the ossa coronce of both legs were somewhat larger than 
they ought to be, yet the periosteum was white and free 
from any abnormal appearance; the tendons also glided 
freely in their sheaths, and the sesamoid bones were like¬ 
wise in a perfectly normal condition. 
The heart was found to be extensively diseased, and I 
cannot but think that from this cause, not onlv the consti- 
tutional symptoms arose, but also the lameness. The right 
ventricle was much diminished in size, while its walls were 
greatly thickened. They presented in their substance a 
gritty and mortar-like deposit, which Assistant-Professor 
Varnell, who subsequently examined the specimen, pro¬ 
nounced to be tuberculous. The other viscera were healthy. 
Lameness from liver disease, as is well known, is not 
uncommon, owing probably to the nerves from the hepatic 
plexus uniting with those which supply the fore limbs. As 
nerves from the cardiac plexus are also mingled with the 
axillary, it is not unreasonable to suppose that lameness 
may occasionally be a consequence of heart disease as "well as 
of liver. 
CASE OF DIFFICULT PARTURITION IN A MARE 
FROM PRETERNATURAL PRESENTATION OF 
THE HEAD, WITH THE FOUR FEET; SUC¬ 
CESSFULLY TREATED. 
By James Brydon, V.S., Peebles. 
The profession is very much indebted to jmu for the 
liberal space given in your valuable Journal to the important 
subject of difficult parturition in mares, and its operative 
treatment. The papers of Mr. Galley and of Mr. Balfour 
have had the effect of calling forth useful practical contri¬ 
butions from other veterinary surgeons, and perhaps you will 
not consider my communication unworthy a place in your 
columns, as the case it details belongs to the same order of 
labours, and corroborates the rule of practice now sought to 
be established, viz., that the life of the mare ought not to be
