BRONCHITIS. 37 
The neck may also wisely be bandaged with a flannel wet with kerosene oil, 
over which there should be placed another, but dry, flannel. Or if the respira- 
tion is much impeded, it will be advisable to attempt to relieve the congestion or 
spasm within by the means of a large sponge wrung out in hot water. This 
should be applied to the front of the neck, lightly bound with a napkin, and 
changed every few minutes. 
Internal medication is not easy, owing to the resistance offered, and should 
therefore be attempted only where it seems urgently demanded. Of the various 
agents which act well in this affection, the oil of copaiba is one of the very best; 
and it can be given in doses of fifteen drops as often as every third hour if the 
attack is severe. It should be emulsified as follows: Add a teaspoonful of it 
to a raw egg, beat well with a fork, and give one-fourth of the entire quantity at 
each dose. 
Where suffocation is threatened, inhalations of steam may relax the affected 
parts and so open the larynx a little ; and in order to apply them, the dog should 
be put into a small room in which there is a common washing-tub holding water 
to the depth of one or two inches. In this a hot flatiron or brick should be 
dropped every few minutes. 
When suffocation is imminent and all other means have proved futile, the 
operation known as tracheotomy is the only chance remaining. In this the 
operator cuts through the neck into the windpipe and below the swollen larynx. 
But it is truly a forlorn hope; moreover, there are but few men outside of the 
surgical profession who can rightly undertake it; and should it become neces- 
sary, the best surgeon within reach should be obtained. The owner will do well 
to tell him, if he has never performed the operation on a dog, that he must 
make his way very carefully; and at best he is likely to have troublesome 
hemorrhage. 
It is important to remember that a symptom which is considered highly 
characteristic of rabies, and one that usually appears early in the disease, is the 
peculiar alteration in the tone of the voice. The bark is described as a sound 
between a bark and a howl, uttered in a rough, hoarse tone, which might be 
called croupy, and is attributed by some to a swollen condition of the pharynx 
and larynx. 
Chronic laryngitis scarcely requires other than hygienic treatment. 
BRONCHITIS. 
An inflammation of the lining membrane of the bronchial tubes constitutes 
bronchitis. It may be acute or chronic. Both forms can properly be considered 
together, for reasons that will appear anon. ‘The acute is rightly designated a
