Sept. 7tli, 48 more were subjected to the operation. The 
weather on this day was colder, if anything, than on the previous 
day. 
Sept. 8th I operated on 48 head more, the day being clearer 
than the preceding two, but the temperature was about the 
same. 
Sept. 9th I operated on 18 head, making in all 138 cows for 
these four days. The weather was clear and slightly warmer 
than on any previous day. 
These cows were with few exceptions pregnant, most of them 
in the first or second month, one being in about the fourth month, 
and all, excepting two, had sucking calves running at their sides. 
The results of the series of operations were by no means as 
satisfactory as those of the former experiment. 
Of those operated on the first day twelve died, making half of 
the total number; eleven died of the 48 operated upon on the 
second day ; nine of the 48 of the third day, and three of the 18 
head upon which I operated on the fourth day. This made 35 
head in all, that died. 
Of these 21 died with gangrene of the peritoneum, with more 
or less serous effusion into the abdominal cavity. The inflamma¬ 
tion in most cases extended throughout the peritoneal membranes 
even affecting the visceral layer as well. 
The gangrene was generally found in the most dependent por¬ 
tions, and in these parts as a rule, the membrane was much thick¬ 
ened by the attachment of false membrane, and what appeared 
to be a coaguable reddish albuminous infiltration into its tissue, 
in many cases reaching the thickness of from 1^- to 2 inches. 
Where the inflammation was extensively diffused and extended to 
the vagina, the incision in the upper wall of that organ had not 
cicatrized. If it had not reached as far, the cicatrization was 
generally in progress, if not complete. In very few of these cases 
was the broad ligament, from whence the ovary was taken, gan¬ 
grenous, and in none of the cases could I see any indications of 
the inflammation in that part having been the cause of the fatal 
lesions. In these cases no blood-clots were found in the perito¬ 
neal cavity.
