INFLAMMATION OF THE LUNGS. ‘389 
fatal. When acute it is a very dangerous disease, and is charac- 
terised by quick and laborious breathing, accompanied by a snoring 
kind of noise. There is also a hoarse and evidently painful cough. 
Pulse quick and sharp, and some degree of fever. he treatment 
must be active, or it will be of no use. Large bleedings, followed 
by a calomel purge (12) and the fever powder (50), will be-neces- 
sary; but no time should be lost in calling in skilful aid, if the 
life of the dog is of any consequence. 
Chronic laryngitis attacks the same part, but comes on insidi- 
ously, and is shown chiefly in a hoarse cough ‘and stridulous bark. 
It is best treated by a seton in the throat, together with low diet 
and the alterative pill (1). 
Bronchocele is known by an enlargement (often to the size of 
the fist) of the thyroid body placed just on each side of the wind- 
pipe. If this does not press upon the air-passage there is no 
inconvenience ; but in course of time it has that ill effect, and the 
dog becomes wheezy and short-winded. It is chiefly seen in house- 
pets, and. may be relieved by the internal use of iodine (3), given 
for weeks together. 
INFLAMMATION OF THE LUNGS. 
The organs of respiration consist of an external serous and an 
internal mucous membrane, united together by a cellular tissue, 
and each of these is the seat of a peculiar inflammation (pleurisy, 
pneumonia, and bronchitis), attended by different symptoms and 
requiring a variation in the treatment. There is also, as in all 
other inflammations, an acute and a chronic kind, so that here we 
have six different inflammatory disorders of the contents of the 
chest, besides heart disease and phthisis or consumption, which 
last requires a separate notice. All the acute forms are attended 
with severe sympathetic fever, and with a quick pulse; but the 
character of the latter varies a good deal. The chronic forms 
have also some slight febrile symptoms, but generally in propor- 
tion to the acuteness is the amount of this attendant on sympathetic 
fever. As these three forms are liable to be easily mistaken for 
each other, I shall place the symptoms of each in juxtaposition in 
the following Table :—
