550 SCROFULOUS DIATHESIS IN A BULLOCK. 
and developed in various parts of its surface. Otherwise, the 
appearance of the gland was healthy. 
I next examined one of the kidnies, which was considerably 
enlarged. Upon passing a scalpel through a portion which seemed 
lighter in colour and more prominent than the rest, there was a 
grating sound, as if it had come in contact with small gravel, 
followed by an escape of a fluid, resembling pus, contain- 
ing flocculi of a curd-like matter in suspension. On passing 
the finger into the orifice made by the scalpel, it had a peculiar 
gritty feel, and contained something of a seemingly calcareous 
nature embedded in the glandular substance. 
My attention was next directed to the mesenteric glands, 
which were of an unusually large size, and when put into the 
scales they weighed lbs. They seemed to be composed of 
a mass of tuberculous matter, in various stages of development. 
On opening some of them, they presented a dark yellow appear- 
ance, of dense consistency, and the gritty feel before mentioned. 
Others were of a lighter colour internally, and looked as if the 
matter was in a state of disorganization. Others, again, presented 
large internal cavities, and as soon as pricked by the scalpel sent 
forth a fluid resembling whey, which emitted a peculiarly faint 
odour. 
The heart next came under my observation, as presenting a 
very peculiar appearance. In the first place, it was of very large 
size ; the total weight of matter contained in the pericardium 
being 28 lbs. ! On passing a scalpel through the fibro-serous 
membrane and its contents, on a line, as near as possible, with 
the septum ventriculorum, I was very much surprised to observe 
the heart itself totally enveloped, from its base to its apex, in a 
dense mass of tuberculous matter, varying from two and a half 
to four and a half inches in thickness. Unlike the other morbid 
products which I have described, this seemed to present one uni- 
form state of development. There was no softening either in 
the centre or the circumference, but a similitude of structure 
throughout. 
The substance of the heart itself appeared to be in a state of 
atrophy; the muscular fibres being pale in colour, and loose in 
texture. I carefully examined the tricuspid, mitral, and semi- 
lunar valves, without being able to discover any tubercular 
deposits ; indeed, the interior of the organ was perfectly normal, 
with the exception of an osseous deposit in the septum auricu- 
lorum. 
By careful dissection, I could separate the pericardium from 
the tuberculous matter, to which it seemed to be attached by a 
layer of areolar tissue. Probably my dissection might be faulty ; 
but when I attempted to separate the morbid deposits from the
