PATITOGNOarONIC SYMPTOM 93 



A PATHOGNOMONIC SYMPTOM OF FETAL 

 DEATH 



It is a common occurrence for the practitioner to be 

 called in attendance on cows heavy in calf and pre- 

 senting symptoms of a somewhat doubtful character. 

 These cases, in cows nearly due to calve, are always 

 important from the standpoint of their effect on the 

 reputation of the attending surgeon. An error in

 cow. 



A variety of pathological conditions within the uter-

 changes. This twitching of tl^e vulva is also seen in 

 other diseases, but, in cows nearing the end of the 

 period of gestation it is a sure diagnostic sign of fetal 

 death when accompanied by fever, anorexia and other 

 usual symptoms. 



For many years I have not hesitated to base my 

 diagnosis of fetal death on this sign and I have never

 is reliable when the fetus is dead and undergoing de- 

 generative changes. 



I have not been able to test its reliability in other 

 animals than cows, in fact, -am not sure whether it is 

 a symptom in other animals. However, in the cow I 

 have so much confidence in this sign that I never hesi-
