The stomach was merely full, but not at all distended. 
Observations .—1 am sure that this rupture was quite a recent 
affair, from the appearance of the ruptured edges of the perito¬ 
neum, and the spleen did not exhibit any chronic or other 
disease. It was, perhaps, fully as large as that viscus is generally 
found to be; but the size varies considerably while the animal 
remains sound. He had never been known to be unwell, and 
during the last three days all the quick exercise he had had was 
merely a short trot or slight gallop in a charge or two each day. 
His feed had been hay, and nine or ten pounds of corn a day. He 
was in fair condition, and by no means fat. His work had been 
generally in the team. I think it not at all improbable, that had 
this horse been ridden in the ranks on the day he died, he most 
probably would have fallen in some of the charges. 
I am aware of only one other case like it on record in any of 
our English works, and that is to be found in the second volume 
of Mr. Percivalfs Lectures.

RUPTURE OF THE TRACHEA IN A SAMBUR DEER. 
1838, May 14M, 10 p. m. —I was sent for in great haste To 
see this animal, whose breathing had suddenly become most dis¬ 
tressingly laborious, and almost threatening immediate suffocation. 
I found her in the deer-house, but I could hear her breathing at 
least ten yards from the door. Her head was protruded, and her 
flanks heaving, and her countenance expressing the greatest dis¬ 
tress. She was always a wild and untractable animal, and 
could not have been caught when in health without extreme 
danger to herself and to the keepers. In her journey to us from 
Kingston farm, three years ago, she had bruised herself in every 
part. To have endeavoured to catch her in her present state of 
distressed respiration would have been certain destruction to her. 
I ordered two drachms of emetic tartar to be dissolved in her 
water, and a drachm of calomel to be concealed in bits of marifjel 
wurzel, of which she was particularly fond. 
15M.—I saw her again very early in the morning. She had 
eaten the mangel wurzel, but she had not touched the water. 
Her breathing was no longer to be heard until we came close to 
her, but there was more than usual heaving at the flanks. She
