UPON THE TRANSMISSION OF INFECTIOUS DISEASES BY 
MIASMATIC CONTAGION. 
By Messrs. Cadeao and Malet. 
Not finding in the expired air a cause of contagion by dissem¬ 
ination of the germ, the authors have endeavored to discover 
whether the contagia carried in the atmosphere by putrid emana¬ 
tions, or if infected waters, swept by the air, could distribute a 
portion of the micro-organisms they contain. 
To solve these questions, they exposed a series of animals, in 
a quiet and undisturbed media, to the inhalation from cadaveric 
detritus from animals which had died from various virulent dis¬ 
eases, as small-pox, anthrax, tuberculosis, glanders and septicemia. 
None of these diseases were transmitted by the cadaveric emana¬ 
tions, even when the normal evaporation was slightly increased by 
heat, or when the detritus were exposed to strong drafts of air. 
As supplementary evidence, they inoculated the water ob¬ 
tained in condensing the vapors of water contained in the products 
of these putrid emanations, but still obtained only negative re¬ 
sults. 
The experiments to determine whether the germs carried away 
by water could be made free in the atmosphere by the influence 
of the wind which swept over its surface, remained also negative. 
So long as the water was not entirely evaporated the germs re¬ 
mained in the fluid.— Journ. des Set. Med. 
ETIOLOGY OF GLANDERS. 
By Mr. Loeffler. 
He has found that several animals may easily be inoculated, 
the guinea-pig and the field-mouse especially. Three or four days 
after the sub-cutaneous inoculation, an infiltration of the tegu¬ 
ments, with irritation of the lymphatic and corresponding glands, 
takes place. The viscera are also rapidly involved, and multiple 
lesions are found in many of the organs, as the spleen, the liver 
and the lungs. 
The coloration of the bacillus is obtained with the solution of 
Loeffler (1 cc. of alcoholic solution of the blue of metliyline, and
