to determine the effect of cold upon the virus of this 
epizootic. 
They record that a “ P.P.” lung which had been frozen, re¬ 
tained its virulence over one year. The lymph obtained from 
this lung possessed the same activity as that derived from a 
recently slaughtered animal suffering with the disease. The 
contents of the bronchias of the frozen lung, when inoculated 
in healthy animals, produced positive results after the lapse 
of several months. 
Upon this ground the observers warmly recommend this 
method of freezing as an acceptable way of conserving pure 
and diluted virus of contagious diseases, and also as a means 
of preserving fresh anatomical preprarations intended for 
demonstration .—Reportoire de pol., 1891. 
CROUPOUS VAGINITIS AND METRITIS. 
In a stable kept scrupulously clean, one or more cows at 
various times became sick with septic metritis. This always 
ended unfortunately in spite of immediate veterinary assist¬ 
ance. At the end of the present year we were again called in 
to inspect a cow in severe labor, and which at every pain 
threatened to prolapse the uterus. Examination of the 
uterus, which in the last parturition had protruded half its 
length, revealed it to be in a normal position. With the ex¬ 
ception of a few small wounds, which might have been caused 
by obstetrical instruments, no injury was detectible. Chloral, 
ice, etc., operated in no degree to diminish the straining. The 
uterus was irrigated with a 1.5 per cent, solution of' creoline 
in quantities of ten liters three times daily. The expulsive 
efforts and temperature of 104° F continued. On the eleventh 
day we removed a complete counterpart of the uterine cavity, 
composed of a tough, schirroid deposit; shortly after the 
morbid symptoms disappeared.— Woch.f. Th . u . Vh. 33. 
AZOTURIA. 
As early as 1874 Thomas communicated that azoturia 
was more prevalent in years yielding a good wine crop, as in
