and bronchitis in horses, the truth or fallacy of a doctrine which 
has been so extensively promulgated is surely a subject of the 
highest importance.

PNEUMONIA AND PHTHISIS. TWO TIGERS. 
THESE animals were apparently well on the 16th of January, 
1839. Beautiful creatures they were — the coat sleek — the eye 
bright — in high condition, without being over-fat, and not one cir- 
cumstance to engender suspicion. 
On the 17th, in the morning, the tigress had cough — the act of 
coughing was evidently painful — her coat stared — she heaved at 
the flanks — the countenance was depressed — the muzzle, although 
not hot, was dry, and considerable fever evidently accompanied the 
cough. Give her three grains each of calomel and antimonial powder, 
and put her on short commons. 
18^A. — The bowels have been opened — the faeces have a bilious 
character, and are very offensive. The expression of her counte- 
nance is worse, and she heaves quite as much as, or more than 
yesterday. Repeat the medicine. 
19 th. — The medicine has operated, and is still operating — the 
cough is not so violent, but the heaving at the flanks is fearfully 
increased. There is evidently acute inflammation of the lungs : 
and, painful experience in former years having convinced me that 
this too soon becomes connected with tuberculous disease or hastens 
the appearance of it, I was anxious to accomplish, if possible, a 
double object. I therefore determined to attack the pneumonia by 
constant purgation, and to check the progress of tuberculous deve- 
lopment by the iodine. She was now purging, and I prescribed 
three grains of the iodide of potassium morning and night. Bleeding 
was out of the question — even Van Amburgh could not effect it. 
This purging continued three days, and was then recalled by the 
calomel and antimony, until she began to refuse both this and the 
iodine, which was after about a fortnight. The purging was kept 
up a few days longer by olive oil in fat broth : when that failed, 
an ointment of calomel was rubbed on her paws ; but this she dis- 
covered at the expiration of two days. The mercurial ointment
