INTERESTING CASES.

there would be sufficient gradual dilatation of os to permit of 
easy extraction of the foetus, which was at the date of examina¬ 
tion still alive and vigorous in its movements. 
On the following day the patient could rise with less assis¬ 
tance and had shown some slight labor pains ; the os was 
moderately dilated, the foetus dead and emphysematous and 
required considerable force for its extraction, after which the 
cow seemed much exhausted. A stimulant was administered, 
and the patient placed in comfortable quarters. Although much 
of the amniotic fluid had escaped through the os, a great deal 
remained, the long continued over distension having apparently 
produced uterine paralysis. 
Three hours after removal of the foetus the cow died from 
exhaustion.

The autopsy showed a very thin chorion and uterus, the 
body of which was practically obliterated, the hydrops having 
been confined to the two cornua. 
This change in relation between uterus and cornua consti¬ 
tuted an interesting feature in the case. When dilating the os 
at the time of the first examination, directl}^ in front of the os, 
centrally located and perpendicular, was a thin band, the nature 
of which we failed to determine. The autopsy showed this to be 
the point of juncture between the two cornua which instead of 
being located several inches in front of the os intern, as in the non 
gravid or normal gravid uterus, was in direct contact with the os. 
The uterus was intact in every part except slight lacerations 
at the cornual juncture, which, however, were of no significance. 
There were no notable deviations from the normal observed 
in any organs, except the large flaccid uterus. 
In a herd of lo dairy cows the owner had lost one previous 
to the case here recorded, undoubtedly of the same affection and 
but two days prior to our visit. 
The results in this case indicate that the proper method to 
pursue, is to complete at once the dilatation of the os and evac¬ 
uation of the uterine contents by physical* force, and not leave 
this to be accomplished by labor pains after rupturing the mem-
