620 CONTRIBUTIONS TO COMPARATIVE PATHOLOGY. 
Aug. 1st . — The tumour has not increased, but it is as large as 
ever. It is of the size of a sparrow’s egg. 
3d . — It is evidently increasing. I will wait another day or 
two — it may point and break. 
4 th . — It is not larger than yesterday, but it is thoroughly and 
uniformly hard. Give three grains of the hydriodate of potash 
daily. 
(ith . — The tumour is rapidly abating. The storm is passing 
over for the present. Continue the iodine. 
8th . — The tumour has disappeared. Continue medicine. 
16^/i. — The medicine had been continued to the present day. 
The animal was as full of play as ever, and apparently in perfect 
health this morning. One of the council was there, and was ad- 
miring him. Another gentleman saw him two minutes afterwards. 
He was still at play. In less than two minutes more he was 
found dead. On first opening him, the contents of the abdomen 
seemed to exhibit every appearance of perfect health : but on 
examining more closely, a tumour, nearly the size of a bantam’s 
egg, was found to be attached to the anterior portion of the 
mesentery. On opening the stomach, six flattened tumours 
appeared ; two of them a full inch and a half across, and seem- 
ing to be situated in the submucous tissue. I considered them 
as being of a strumous character, and was connecting them in 
my mind with the tumour that a little while before had appeared 
under the jaw. I would not cut into them, but sent them to 
Mr. Owen, at the Royal College of Surgeons. He makes the 
following observations on them in the Proceedings of the Zoolo- 
gical Society of London, 1836, p. 123 : — “ I received, a few days 
ago, from the Medical Superintendent of the Society’s Mena- 
gerie, the stomach of a young tiger, exhibiting on the internal or 
mucous surface what he at first considered to be scrofulous 
tumours. They were five or six in number, of a round and 
oblong form, varying in size from half an inch to two inches in 
the largest diameter, and the largest of them projecting about 
half an inch from the plane of the inner surface. They made no 
projection externally. The mucous membrane covering the 
smaller tumours was puckered up into minute reticulate ruga ; 
the surface of the largest was smooth. On wiping away the 
tough thick mucous secretion from the tumours, and examining 
more closely their surface, two or three orifices presented them- 
selves in the larger, and a single orifice in each of the smaller 
tumours. These orifices conducted to irregular sinuses, which 
were the nidi of two kinds of Nematoid Entozoa , some measuring 
nearly an inch in length, and a line in thickness. The others 
were more minute, not exceeding five lines in length, and one-
