cartilage of tire extremity of the scapula and humerus removed 
by ulceration (which in several spots extended through the epy- 
physis of the humerus) and attrition. The whole of the bones of 
the fore extremities were of great specific gravity, had a dark 
appearance externally, and were easily cut with the knife. The 
weight of the humerus after maceration for some weeks (without 
the superior epiphysis and apophysis) was 19 oz., the fat contained 
in the medullary canal of a longitudinal half weighed 3 oz., the 
shell 61 oz. 
I am not aware of Mr. Rutherford's reason for arriving at the 
conclusion that the animal had suffered from an attack of quarter- 
ill. I am of opinion that the appearances presented had arisen 
either as the result of an exudative blood disease—the medullary 
canal and cancelli becoming filled with the exudation, which ulti¬ 
mately underwent fatty degeneration—or as the consequence of 
mal-nutrition of the blood. 
Professor Walley exhibited morbid specimens from both sub¬ 
jects—viz., the diseased valves and a portion of the heart of the 
colt, with the te fibrinous deposit" found in the hock-joint, also 
a section of the humerus of the stott, in which the excessive 
accumulation of fat in the medullary canal, and the pecu¬ 
liar state of the bone itself, were very distinctly shown. He 
also showed the diseased humerus of a cow, which he stated 
had been forwarded to him by Mr. Dewar, Y.S., Midmar, the 
case having been one of medullary abscess, which had become 
evacuated through several oval apertures in the external surface 
of the bone, leaving a considerable cavity, with dilatation of the 
compact structure, and numerous external exostotic deposits—a 
very beautiful specimen indeed of this comparatively rare disease. 
Mr. Cumming gave details of a somewhat peculiar aphthous 
affection in a horse, in which the appearances presented on the 
mucous membrane of the mouth were almost exactly similar to 
those seen in the foot-and-mouth disease of cattle. No apparent 
cause could be assigned—no drenching with turpentine or am¬ 
monia or such like, nor any injury by halter or otherwise. A 
few days on sloppy diet, with mild astringent lotion to the raw 
surfaces, and the horse recovered. 
Before the discussion of his essay on parturient apoplexy, read 
at last meeting, was proceeded with, 
Professor Walley asked permission to say a few words relative 
to the subject, and read a communication from Mr. Aitken, 
Y.S., of Dalkeith, which that gentleman had forwarded to him 
along with the head of a heifer which had succumbed to partu¬ 
rient apoplexy. (t The animal was seven years old, and had 
suffered from an attack four years previously (having had three 
calves in the interval). She was attacked very suddenly on the
