502 DIFFUSED TUBERCULAR DEPOSITIONS. 
free from lymph. On July 3d, the reply to my note was — if 
the horse was not dead, to have him killed immediately. 
On July 5th he was destroyed, and on opening the abdo- 
men there were several enlargements found to exist on the 
peritoneum, and the liver was also quite studded wdth them. 
The diseased viscera of the chest, which I sent to you, 
weighed 43lb. I beg to add, that your remarks upon them 
will much oblige, 
Dear Sir, 
Your obedient servant. 
Professor Spooner. 
[We have been favoured with the following description of 
the diseased viscera : 
“The morbid parts sent to the College by Mr. Stanley 
had become partially decomposed before they were examined. 
Nevertheless, we were enabled to make out the changes that 
had taken place tolerably well. 
“ The pleura pulmonalis, as well as that portion of the 
membrane which covers the fibrous pericardial sac — which 
was very much thickened —was covered with fibrous tumours 
of various sizes ; occupying as much space in the thorax as 
the heart itself. These tumours, especially those around 
the base of the heart, were clustered together something 
like bunches of grapes ; many of them, however, were as 
large as small apples. Those connected with the pleura 
covering the lungs, were found not to involve the structure 
of the lungs, but to be simply adherent to the serous mem- 
brane and its subcellular tissue. 
“The bronchial lymphatic glands were much enlarged from 
external as well as interstitial deposit. 
“ On making a section of these tumours, their character, as 
viewed by the naked eye, was perceived to be fibro-cellular. 
The microscope developed large nucleated cells, of an irre- 
gular ovoid in form, with only a very few elongated nucleated 
cells. 
“ I am doubtful of the disease being cancerous in its nature. 
Still there are some features about it which make it rather 
suspicious ; such as the striated appearance of the cut sur- 
faces of the tumours ; the unhealthy state that the one on 
the tail assumed when it was interfered with by an opera- 
tion ; the character of the cells as seen microscopically ; and 
likewise, the disposftion of the tumours to form in so many 
parts of his body. There can, however, be no doubt of the 
disease having been constitutional in its nature.”]
