232 SYNOPSIS OF CONTINENTAL VETERINARY JOURNALS. 
professionals of mine, with whom I have discussed the 
matter, are equally sure of having had such cases. Veteri¬ 
narians who are called to give their attention to working 
oxen ought frequently to meet with this disease. Let us 
hope that all our readers who have had experience in this 
matter will publish their experiences. I publish the his¬ 
tories of two cases, which I have had an opportunity of 
examining post-mortem. The lesions which I have met 
with differ so much from those of epizootic pleuro-pneumonia 
that, I doubt not, unprejudiced minds will allow that I had 
not to do with cases of that disease. Further, these tw T o 
cases seem to point out, by the difference of their lesions, 
that the lungs of the ox may present a pneumonia similar 
to that of the horse, and besides another form, unknown in 
the horse, due to the special structure of the lungs of the 
ox, of lobules separated from each other and almost 
independent. 
Case I. Pulmonary congestion, with interlobular hsemor- 
rhage in a cow.—The lesions presented in the lobules are 
those assigned to the congestive stage of pneumonia, but, 
in addition, interlobular hsemorrhage, by the compression 
which it exerted on the lobule brought about closure of the 
bronchial tubes and air cells, just as a pleuritic effusion does 
and very seriously aggravated the pulmonary congestion. 
Does this interlobular haemorrhage, which has not yet been 
described, as far as I know, occur in all cases of sporadic 
pneumonia in the ox; and, if so, is it a direct result of the 
special structure of the lungs of the ox, and will it replace the 
yellow infiltration of pleuro-pneumonia ? This is not so, for 
the lung of the ox may be congested without such complica¬ 
tion as Case II shows, for it is one of simple pulmonary con¬ 
gestion in a cow.—These two animals, of which I have just 
been speaking, lived with other animals of the same species, 
no sanitary precautions having been taken, and not the 
slightest sign of transmission of their disease, such as would 
have occurred had they been contagious pleuro-pneumonia, 
was observed. Pending new observations, which will 
definitely teach us if the ox from the special structure of 
his lungs may suffer from several kinds of pleuro-pneumonia 
sporadica, I believe I am right in stating that the lungs of 
this animal may present congestive lesions quite different 
from those of exudative and epizootic pleuro-pneumonia; 
in other words, may be affected with a simple pneumonia 
truly inflammatory and apparently completely devoid of con¬ 
tagious properties. But are the sporadic and contagious 
diseases readily distinguishable in the living animal ? lam
