eration or tissue metamorphosis begins, fitting it for being 
cast off-at time of parturition, it must necessarily be that the 
blood at this time contains a very great amount of fibrine 
and effete material, thus predisposing to congestions, throm¬ 
bi, etc. 
Two or three cases, to which I will call your attention, 
certainly died from the effects of blood clots in the vessels. 
A full blood Shorthorn had delivered her sixth calf some 
eighteen hours before the attack. On arrival I found the 
cow down, unable to get up ; in high condition and a strong 
milker; had given a good flow of milk the evening before. 
After twenty-four to thirty hours the bowels responded to 
the action of a cathartic which we had given ; the urine was 
voided naturally and all seemed to be progressing favorably. 
On the third day the cow got on to her feet, walked about 
the stable lot after her calf and I discontinued my visits. 
On the fourth day she was turned into the house lot, picked 
a little grass, and as the owner afterward informed me, seemed 
to be all right. He left her then for about an hour and on 
returning found her dead. He said he had made an exam¬ 
ination of the internal organs as best he could and found 
nothing that seemed to him abnormal except the liver, which 
was enlarged and contained a great quantity of clotted blood, 
and seemed to be almost in a state of decomposition. 
Another case, very similiar, only that she lay in a perfectly 
comatose condition for about thirty-six hours, then got on to 
her feet, bowels moved quite naturally, and apparently im¬ 
proved rapidly from twelve to fourteen hours, when an un¬ 
favorable change was noticed, and death occurred in less 
than thirty minutes. No autopsy was made. 
The next case was a ver}^ large, fat cow that had been 
highly fed on a nutritious diet with the view of having her 
in good condition for calving and milking. Gave birth to her 
fifth or sixth calf in the morning, and symptoms of the dis¬ 
ease were noticed at noon. I arrived shortly after and found 
her unable to get upon her feet; prescribed salts and gam¬ 
boge, and kept down accompanying tympanitis with spr. 
amnion, and ether. By the next morning this case got up
