REPORTS OF CASES.

he had an attack of pleurisy and some pneumonia. I applied a 
good mustard paste to the chest, and relieved his condition. 
His general condition did not improve, gradually reducing 
in flesh, loss of appetite, legs swelling again, and also on 
breast. About a week ago I found an odor to the breath, and 
said suppurative pneumonia. Yesterday I had him killed; 
post-mortem this morning. There were probably two or three 
stable pailfulls of fluid in the chest. Both lungs more or less 
adherent to the costal pleura. The lower third of both lungs 
showed pneumonia, and there were small abscesses where 
suppuration had commenced, but not what one would call a bad 
case of suppurative pneumonia. On removing the lungs from 
the heart and its vessels, I found this mass which you have in 
the keg. It is something new to me, and I would like to have 
your opinion on it. It filled the space between the two lungs, 
extending nearly back to the diaphragm and way forward into 
the muscles of the thorax. This mass came out with the lungs, 
and so I did not save any more of it. The other part was 
beginning to break down, and was very fetid. 
This description is not as extended as you might wish, and 
if you want more I will write it. 
Weight of mass, 13 lbs. It was put in strong alcohol, so as 
to be fit for slides and to preserve the shape. 
What is it? What caused it? Is it tubercle? 
[Specimens Examined, —Two distinct tumor formations removed from mass 
surrounding aorta and oesophagus. 
In both cases they consist of lymphoid or adenoid tissue; i. e ., delicate retriculum 
and lymph cells, the one harder than the other, and larger base excess of fibrillated 
bands or net-work, and is the older formation. The softer tumor consists largely of 
cells with fine net-work. No degeneration is noticeable, and therefore they probably 
belong to the lymphomata, which originate usually from lymphatic glands. Clinically^ 
are innocent tumors, except as lymphadenoma.]
