HYPERTROPHY. 
upon being reminded thereof, I recognised the case, and 
referred to my minute of the preceding year. 
“March 5th, 1855. Chesnut horse lame of both fore legs, 
most so of the off, from enlargement and disease of the fetlock 
joints. 55 
Cold applications were again advised, but no other treat- 
ment was adopted, as I considered “ blistering 55 would do little 
or no good : I was also unwilling to hold out too sanguine hope 
of success from “ firing ” The horse in the course of time 
again returned to the country establishment of his owner; 
and the next I heard of the case was during the past month, 
December, when the gentleman called to tell me that he 
had had the horse destroyed, and wished me to examine 
the legs, to ascertain whether the lameness would have 
admitted of cure. He stated that he became worse when 
allowed to rest, and far too lame to be continued at his 
work. 
I wish to remark, that the enlargement of the fetlocks, 
alluded to in the reports of my examinations, was lateral 
and involved both the inner and outer side of each joint, 
being most marked on the outside of the off leg, and that there 
was also interstitial thickening extending about a couple of 
inches upwards between the suspensory ligament and can- 
non-bone. 
On dissection, a general enlargement of the lateral liga- 
ments was observed, with disease of each outer sesamoid bone, 
the only difference in the corresponding joints being that the 
offleg was more extensively affected, and accordingly I selected 
it for presentation to the College. Exostosis existed on the 
outer surface, and absorption of nearly the whole of the arti- 
cular cartilage. The denuded bone was discoloured, and 
shewed the effects of attrition in furrowed indentations. The 
corresponding portion of the condyle of the metacarpal bone 
was in precisely the same condition.

On the evening of the 16th of September, 1855, my 
attention was directed to a white horse belonging to the
