is no more applicable to the disease than to pneumonia, in which it 
does sometimes terminate. 
This form of bronchitis, which I have just described, seems to 
consist of a less acute inflammation of the mucous membrane, not 
affecting materially the submucous tissue ; and, if not commencing 
in the membrane of the trachea and bronchi, to have extended 
to those parts from above downward, and limited in this situation 
to the mucous surface; but should the inflammation be more active 
and acute, and involve the submucous tissue in its action, at the 
same time extending more generally through the bronchi, the dis¬ 
ease has then assumed the true or sthenic form of bronchitis.

Since I had the pleasure of forwarding a communication rela¬ 
tive to this destructive malady in young cattle, I have had still 
further opportunity of testing the value of lime-water, alternated 
with a solution of salt in water, in curing it. It is, as I have said 
before, an affection dependent upon the development of an innu¬ 
merable quantity of worms, of the filaria species, in the cells and 
bronchial tubes of the lungs, which create only a certain ^quantum 
of irritation in that viscus and the mucous membranes of the 
bronchi as to keep up that extent of secreted fluids just adequate 
to their demand for their support; but which brings on a constant 
cough, quickness of breathing, rapid loss of condition, and, ulti¬ 
mately, either wears the animal out, or else suffocates it by their 
extraordinary accumulation, accompanied with a correspondent in¬ 
crease of secreted fluids. It is an affection not confined to cattle, 
for we find it in other animals, as sheep, deer, &c., and not ex¬ 
empting even man himself. I have often considered hooping-cough 
as bearing a very strong analogy to it; and it would be well to try 
how far the same remedial measures would avail in this disease; 
and also, when opportunity serves, to make post-mortem examina¬ 
tions to ascertain whether it has not a similar origin. In that very 
valuable work, “ The Naturalist’s Library,” conducted by Sir 
Wm. Jardine, Bart., F.R.S., F.L.S., &c. &c. (a work which ought 
to form a portion of every agriculturist and every veterinary sur¬ 
geon’s library, whether as regards its extreme cheapness, the va¬ 
luable matter it contains, the beauty and fidelity of its plates, which
