PATHOLOGICAL ANATOMY, 
TUBERCULOSIS IN DOMESTICATED ANIMALS. 
From the observations of European investigators it ap¬ 
pears that spontaneous animal tuberculosis is not so laie 
amongst some of them as it has seemed to be. In the Revue 
des Sciences Medicates mention is made of a dog which had 
died from a natural attack of tuberculosis, in which the liver, 
kidneys and other abdominal organs were found Filed with 
softish tumors having a sarcomatous appearance. The bac¬ 
teriological examination and inoculation proved that the 
tumors were of a tuberculous nature, with numerous bacilli. 
This fact proves that it is an error to suppose that the organ¬ 
ism of the dog possesses a peculiar serum which gives him 
immunity against tuberculosis .—Revue des Sc. Medi. 
EXPERIMENTAL PATHOLOGY, 
THE REGENERATION OF THE SUBSTANCE OF THE KIDNEY. 
Experiments made by Kummell, of Germany, have proved 
that the removal of a portion of the kidneys, even to one-half 
of the organ, made in the longitudinal or transversal diameter, 
may be followed by the regeneration of the renal structure 
in about eight days. After the ablation of one-third of the 
organ three days only are necessary to restore it to its nor¬ 
mal size. Microscopic examination shows that the new for¬ 
mation is not limited to the connective tissue alone, but 
involves also the parenchyma of the organs and the glomer- 
ide.— Ibid. 
ANTHRAX IN FOWLS. 
In ordinary circumstances fowls are refractory to anthrax. 
Their immunity is due to the phagocytory activity of the 
leucocytes. The bacillus of anthrax can grow and retain its 
virulency in the bodies of fowls, but its inoculation is fol¬ 
lowed by febrile reaction. There are conditions, however, 
in which fowls may become affected with anthrax and sue-
