buted to the improvement of which we have been speaking by 
exciting a noble emulation among veterinary surgeons, which has 
led fathers to bestow a better education on their sons than they 
themselves received, and have thus enabled the sons to profit 
more by the instructions communicated at our schools than their 
fathers were able to do, and more fully to investigate all the in- 
valuable secrets of our art. 
We shall now, gentlemen, lay before you the different com- 
munications of our correspondents, recording the pleasure and 
satisfaction which the perusal of them has given us. 
Contributions from the Correspondents of the Society. 
M. CroSy veterinary surgeon at Milan, has addressed to us five 
cases of practical veterinary medicine, followed by some reflec- 
tions on the carbonaceous disease designated Glossanthrax, and 
on Glanders. 
M. Jacoby chief veterinary surgeon to the eleventh regiment of 
Dragoons and Chevalier of the Legion of Honour, has sent a ma- 
nuscript entitled “ Observations on the Non-contagiousness of 
Chronic Glanders .” 
From the most remote period, glanders, that dreadful scourge 
and the prevalent cause of the loss of so many horses, has been 
considered as a peculiarly contagious disease. The most strict 
legislative measures have been taken, and the most minute and 
careful precautions adopted by government, in order to prevent 
the propagation of what has been considered as a plague or pes- 
tilence until towards the close of the last century, when some 
isolated facts occurred which puzzled the inquiring mind of a 
young veterinarian. Having, in due time, deservedly obtained 
a situation at the Veterinary School at Alfort, he succeeded in 
making some proselytes to his new belief among the professors 
of that establishment ; and from that time the doctrine of the 
non-contagiousness of glanders was professed by a portion of the 
teachers of the school ; and, as every thing that is novel, or which 
departs from old established opinions, is always attractive to the 
inexperienced youth, during the first twenty years of the present 
century the partisans of non-contagion increased so rapidly that 
their opponents soon found themselves in a decided minority. 
Some undeniable cases of the transmission of glanders often, how- 
ever, occurred, and shook the new doctrine to its very foundation. 
The leaders of the anti-contagion party cut the knot they could 
not unravel, by asserting that there were two kinds of glanders ; 
— the one chronic, very common, and not contagious ; the other 
acute, rarely met with, and contagious.
