ture of the surrounding parts—which may consume half an 
hour. This being accomplished, the lips of the vulva are 
brought in juxtaposition by carbolized silk sutures, an aper¬ 
ture being allowed to remain open for the escape of urine. 
The animal is placed in a position favorable to the retention, 
to wit, the posterior portion of the body is elevated for two 
daj^s. In case the expulsive efforts subsequently recommence, 
doses of alcohol and coffee should be administered. After 
ten to fourteen days the stitches are removed, and the animal 
discharged as sound.— Berl. Thier . Woch. 
IMMUNITY AGAINST THE VIRUS OF PUS. 
R-has experimentally confirmed the assertion that ani¬ 
mals having successfully withstood peritonitis possessed, to a 
certain extent, immunity from infection of the abdominal cavi¬ 
ty. He proved that dogs were able to stand large quantities 
of staphylococcus pyogenes aureus when the injections were 
consequently increased from a minute quantity. These ani¬ 
mals were also accustomed to large doses of pus by first re¬ 
ceiving large doses of the ptomain. This confirms the view 
of Briegers that the toxic quality of pus is referable to the 
ptomain. This discovery has the practical worth of demon¬ 
strating that in researches upon pus, the same animal must 
not be used for a number of experiments.— Wochenschrift .
