Diseases of the Respiratory Organs, 45 
It is now pretty generally acknowledged that consolidated 
lung is capable of regeneration, and I have had myself 
practical experience of the fact. Dr. Chambers observes : 
“T have no doubt, in my own mind, that the way in which 
consolidated lung recovers is by the exudated fibrin breaking 
down into pus, and being expectorated, whilst the obstructed 
air vesicles regain their elasticity and capacity for performing 
their functions. This is a strong argument for an ample 
supply of, nutriment during the regenerative process.” 
CONSUMPTION. 
This decimating disease of mankind extends to the lower 
animals, and dogs are frequently subjects in which its fatal 
seeds are sown, 
Predisposing Causes.—Hereditary taint, close confine- 
ment, bad air, unwholesome food, and breeding in and in 
Exciting Causes.—Preceding diseases, as distemper, pneu- 
monia, catarrh, scrofula, asthma. Sudden changes of 
temperature ; damp habitation. 
Sympioms.—Occasional cough; short respiration, ac- 
celerated during exertion, with increased cough ; failing 
appetite ; loss of flesh. As the disease proceeds, profuse 
expectoration takes place, the breath becomes feetid, great 
prostration is manifest, the hair falls off, diarrhoea sets in, 
and the animal dies much in the same way as our own un- 
fortunate species do. 
Treatment.—This can only be adopted so far as the 
‘alleviation of suffering and the prolongation of life are 
concerned : cure is impossible. In the early stages a seton 
in the chest, cod-liver oil and iron, nutritious diet, and the 
avoidance of exposure to damp and cold, will often arrest 
the progress of the disease ; in fact, if thus checked early, 
it will assume a quiescent state, and remain so for a long 
time, or even the natural period of canine existence.
