AN INQUIRY 
INTO THE ETIOLOGY AND PATHOLOGY OF THE VENEREAL DIS¬ 
EASES OF MAN AND OF THE LOWER ANIMALS. 
By CnARLES F. Ring, M.D. 
(Continued from page 282 .) 
THE NEW VENEREAL DISEASE OF SOLIPEDS. 
This brings us to a consideration of the last division and 
closing argument of our study, without which our investigation 
would not be complete, viz.: To an inquiry into the nature of the 
new venereal disease of solipeds, and its relation to human 
syphilis, and hence to glanders. 
“For a long time before the communicability of glanders to 
man was recognized," writes Bollinger, “ the disease had acquired 
a certain interest, as regards its bearing upon human pathology, 
from the circumstance that Van Helmont (1682) sought to refer 
to it the origin of syphilis, a theory adopted at a later date by 
Ricord. The source of this erroneous idea has been traced by 
Virchow to the report—at one time accepted as true—that 
glanders first appeared, together with syphilis, at the siege of 
Naples, towaids the end of the fifteenth century. JVIore recent 
observations liave since demonstrated that the virus of syphilis, 
when introduced into horses, never produces glanders; and it is 
still more significant that syphilis, as such, is never known to 
occur in domestic animals.” {Ibid, article Glanders.) 
It is rather surprising that a veterinary professor and author 
should make an assertion like this, in the face of so much testi¬ 
mony of an opposite character. Tie certainly cannot be unac¬ 
quainted with the new venereal disease of solipeds, to which
