chronic cases to be of a milky-white character, but in some instances 
they were reddish. 
Mr. Gerrard said his experience was that the secretions were more of a 
milky character. Cases of this disorder abounded more in the North of 
England than in the southern counties, as there women were frequently 
entrusted with the case of cows, and often dropped hair and other pins, 
&c., among the animals’ food. He had not previously heard of the 
symptom of the disease mentioned by Mr. Samson, viz. the extraordinary 
swelling of the jugular veins, and would like to know if that gentleman 
observed any regurgitation in this case. 
Mr. Samson stated that in both jugular veins the blood passed freely 
up and down. He stood and watched the cow for half an hour at a 
time. There was no regurgitation. The fluid he exhibited had a most 
offensive smell. Had opened many abscesses, but never came across 
one so foul. 
Mr. Broad exhibited a specimen of the atrophied wall of the right 
ventricle of a mare’s heart. It did not represent all the atrophied 
portion. Four years since he attended the animal for heart disease and 
indigestion. It was laid up for a month. An intermittent pulse, 
stopping after every third beat, existed. The mare went to work, but 
always had an intermittent pulse. Observed no other indications of 
disease. He was called to see the mare a few weeks since and found her 
very ill; while he went to get some medicine she dropped and died. 
He found the abdomen full of dark blood ; could only determine that 
the rupture proceeded from the mesenteric vessels, but from the careless 
way the viscera were removed could not ascertain the cause of the 
rupture. No blood could have escaped from any part but these vessels. 
Over the whole extent of the mucous membrane of the bowels there 
was a thick deposit of gelatinous consistence, as from dropsy. 
The disease appeared to have been present a long time. There 
were miliary and other tubercles both in the lungs and liver, which 
presented the exact appearance answering the description of the cal¬ 
careous tubercle, like a button embedded in the surface. The animal 
was probably twenty years old. The owner had had her some fourteen 
years. He had found some glands removed from the inferior portion of 
the diaphram, which appeared to be diseased. The tubercles were the 
same as found in glanders. There was no rupture in the heart; the 
spleen and kidneys were sound. 
Mr. Shaw drew attention to the remarkable thinness of the wall of the 
heart. 
Mr. Gerrard remarked an intermittent pulse was very common at 
times. He had a case very similar, a six-year old horse. The abdo¬ 
minal cavity was filled with blood. The heart was quite healthy. He 
could not detect anything wrong. It might have been caused by 
galloping, leaping a fence, or something of that sort. Could not find 
where the escape came from. 
Mr. Shaw was at a loss to understand how the mare could work in the 
state she was in, with the wall of the ventricle so thin ; she must have 
been greatly distressed at the least exertion. 
Mr. Broad said that was the case, and he believed the acute symptoms 
were brought on by her having been taken a longer drive than usual. 
When at the Crystal Palace she had a slight attack, and that brought on 
serious illness. She had been in regular work, and was a well-bred mare. 
The Chairman stated that his experience was that heart disease in the 
horse was of common occurrence, and it was the exception, rather than 
the rule, upon making post niortems to find animals with healthy hearts. In
