ic and toxicogenic bacteria in the upper air passages of domes¬ 
ticated animals,” attention is called to a lew attenuated bacteria 
that were found in the air passages of certain healthy animals, 
which resembled the swine-plague group in their biological 
characters. Although the evidence is not at hand to establish 
the fact, our knowledge of the variations that exist in the vir¬ 
ulence of the various members ot the group of bacteria to 
which the bacillus of rabbit septicaemia belongs, indicates the 
possibility of the existence of saprophytic bacteria which, 
when taken into the nasal cavities might, under as yet unknown 
conditions, become more parasitic in their nature, and eventu¬ 
ally produce the rhinitis and its sequela. In septicaemia, 
caused by wound infection, we find a somewhat analagous 
condition, for many of those cases have not been traced to an 
infection by specific bacteria that are capable of living as par¬ 
asitic organisms only. In fact some cases have occurred 
where an infection with germs that have not lived in a condi¬ 
tion that would destroy the known species of bacteria that 
produce septicaemia, seems impossible. Again the experi¬ 
ments of Koch and Gaffky with rabbit septicaemia would in¬ 
dicate the possibility of the existence of these bacteria under 
certain conditions in naiure outside of the animal body.

A.— Histogenesis of the Glanders Tubercle. 
Adult glanders tubercles appear in the lungs of horses 
under the form of rounded nodules, varying in size from that 
of a seed of millet to that of a pea, and irregularly dissemi¬ 
nated in every part of the two lobes. Upon exploration, the 
superficial centers upon slightly raising the pleura give the
