INOCULATION OF GLANDERS IN NERVOUS CENTERS. 
By Tedesohi. 
Animals very susceptible to gdanders (as cats, guinea-pigs 
and rabbits) die more rapidly when the inoculation has been 
made in the nervous centers than when performed in any 
other region. Death is due to general infection. 
Animals having a complete immunity (rats) or a partial 
one (dogs) die also very rapidly by this mode of inoculation. 
The virulency of the microbes obtained in the nervous cen¬ 
ters of animals thus inoculated is greater, and especially if 
these bacilli are taken from animals refractory to glanders, 
but that have died of inoculation. This exaggeration of viru¬ 
lency, positive for the microbes taken directly from the exu¬ 
dates of the cadaver, persists in the cultures to such a point 
that they are capable of killing with subcutaneous injections 
animals that are naturally refractory to glanders. 
In all these cases generalized lesions are found in all the 
organs—congestions, necroses, disseminated miliary granula¬ 
tions of glanders.— Ibid.

PERIODIC OPHTHALMIA. 
This article respects cases in large stables, and relates to 
those which occurred in the tenth Ulanen regiment in Zullec- 
hau. At this place, after the return from practice maneuver, 
three horses became sick of a disease affecting the interior of 
the optic globe; in March, April and May of the next year 
many other individuals in the same military company were 
afflicted with the same disease, which also recurred in the 
three original cases. This left no doubt as to the nature of 
the malady, and an exhaustive investigation of the conditions 
surrounding the animals in this particular barracks was msti-
