Diseases of the Respiratory Organs. 35 
destroying, over an important area, the ciliary action so 
useful for this purpose. The same difference is met with 
‘in human practice. Ordinary acute bronchitis in the adult 
_ is not at all a dangerous affection, while in young children 
it is the reverse ; and for the very reason that in them the 
bronchial mucous membrane swells easily, and there is not 
the same expulsive power to enable them to get rid of 
themucus which, inconsequence, accumulates, and may cause 
collapse or inflammation of the lung tissue. In the ‘lamb 
disease’ death occurs from asphyxia, caused by the collec- 
tion cf mucusin the tubes. I have no records at hand ot 
the state of the lung tissue in these cases, whether it is in 
a condition of collapse or of inflammation ; probably the 
latter, for I see the expression ‘ verminous pneumonia’ used 
by some authors. 
“ With reference to the pneumonic condition of the lungs 
of the dogs in this epidemic, it will be remembered that in 
three of the fost-mortem examinations the inflammation of 
the lungs was found without the occurrence of parasites in 
the bronchial tubes ; the pneumonia being quite as exten- 
sive as in the cases accompanied with strongyles. I must 
confessthat this circumstance has puzzled me not a little, and 
I see no very satisfactory explanation of .the fact. It 
appears natural to refer the diseased condition of the lung- 
substance in the parasite cases to the accumulation of the 
mucus in the smaller tubes producing collapse of the air-cells 
in certain areas, which subsequently became inflamed—a 
sequence of events sometimes observed in children. The 
appearance of the lungs in several of the cases corresponds 
with this view; for the pneumonia was lobular, affecting 
small and isolated portions of the lung-tissue. 
Mr. James Moore, in his work on the homceopathic treat- 
ment of the dog, in his section on “Internal Parasites in 
the Air-Passages,” gives. the following :—

part of the respiratory tube which lies anterior to the larynx,
