UPON THE HISTOLOGICAL ALTERATIONS OF THE LIVER IN 
TUBERCULOUS ANIMALS. 
By Messrs. Cadiot and Gilbert. 
The authors have submitted to a histological examina¬ 
tion the liver of various mammalia, monkeys, dogs, cats, 
guinea-pigs, horses, bovines, which had died with tuberculo¬ 
sis, or which, being thus affected, were destroyed. 
The lesions of the liver in tuberculous animals, like that 
of men, do not exclusively consist in the existence of circum¬ 
scribed tubercles or in tuberculous infiltration. The cirrho¬ 
sis may be met with, and the hepatic cell is not always free 
from disease. The cirrhosis is not common. They found it 
in the incipient stage in one guinea-pig, in one cat, two dogs, 
one horse and one steer. They saw it assume a well-com¬ 
pleted form in one horse of nine years, affected with general¬ 
ized pulmonary tuberculosis with cavities, and accompanied 
with adenopathy of the mediastinal glands. 
The alterations of the hepatic cells are less important in 
the animal than in human tuberculosis. 
The amyloid degeneration (of the vascular coats as well 
as of the hepatic cells) does not exist in animals; and it is the 
same with the pigmentary degeneration. The cellular necro¬ 
biosis is exceptional. The fatty degeneration is also very 
rare. The conditions which give rise to such differences in 
the condition of the hepatic cells in different species during 
the course of some microbian diseases are still unknown.—

THE FAUNA OF CADAVERS. 
By Mr. P. Megnin. 
It is a well known'fact that myriads of insects take posses¬ 
sion of cadavers whose spontaneous generation was accepted 
long ago. The author has observed that these insects (the 
workers of death) appear successively, and in the same regular 
order. He has counted eight different corps d'armee from the 
moment of death to the entire destruction of the cadavers.
