A FEW GENERAL REMARKS ON EQUINE ENZOOTIC 
PLEURO-PNEUMONIA, 
By J. C. Meyer, Sr., Y.S. 
(Paper presented at the United States Veterinary Medical 
Association—Cincinnati Meeting.) 
The familiarity of practitioners with lung diseases in particu¬ 
lar permits me to treat my subject in a general manner, as it 
does not deviate materially from sporadic cases. 
The frequent appearance of this pulmonary complaint how¬ 
ever, characterized by a uniform course, and undoubtedly insti¬ 
gated by the same agencies, induces me to draw the attention of 
my colleagues to this form of enzootic, which is enrolled by the 
majority of contributors to veterinary literature in the category 
of influenza, “ erroneously so called,” Prof. Williams asserts, and 
Prof. Vogel coincides with him. My reason for considering it of 
an enzootic nature, is the incompatibility of the two diseases; 
for instance: when the epizootics of 1872 and 1881 (the genuine 
influenza) set in, the enzootic pulmonary complaint in question 
disappeared, and not another case turned up for half a year or 
more. Now, if they were of the same pathological nature, both 
might exist simultaneously. 
Spring, autumn and winter are the most favored seasons in
