THE BACTERIA IN CONTAGIOUS MALADIES. 17] 
and diphtheria is not, then, yet established by these 
last experiments. 
Typhoid Fever.— Tigri first found bacteria in 
the blood of a man dead with typhoid fever. 
These organisms were also found by Signol (1865) 
and Méenin (1866) in the blood of horses at- 
tacked by a disease called by the veterinarians 
typhoid fever. This blood, by imoculation, pro- 
duced the death of some rabbits, with the same 
alterations in the blood. 
Coze and Feltz (1866), having inoculated some 
rabbits with the blood of typhoid fever, have 
produced results which they consider analogous 
and as accompanied by the same pathological lo- 
calizations in the glands of Peyer. The blood of 
an injected rabbit may be used upon a second 
rabbit, with positive results, as in variola and scar- 
latina. 
The species of Bacterium which is found in this 
case recalls the Bacterium catenula, but its dimen- 
sions are less. 
Glanders and Farcy.— The universal recogni- 
tion of the contagious power of a liquid coming 
from an animal with glanders had, a priori, led 
to the supposition of an element of special con- 
tagion. The first indication was given by Chris- 
tot and Kiener (1868). These experimenters 
discovered in the secretions and vascular glands 
of animals attacked with glanders, bacteria of two 
sorts: 1. Rods, sometimes having a vibratory mo- 
tion without changing place, sometimes having
