 to one side of the crural arch (circus cruralis). This observa- 

 tion is arranged as follows : 



Saake mentions a case where fracture of the ischium 

 was complicated with torsion of the uterus, and where the 

 gravid uterus was felt in the left lower abdominal region on 

 auscultation of that part, faint fcetal heart sounds could be 

 detected. 



St. Cyr and Violet heard in two-thirds of all cases 

 examined by them fcetal heart-beats. They mention also to 

 have imagined hearing the foetal heart one day, not to have 

 detected it the following day, while some days later again 

 the sound became quite perceptive. Eighteen cows closely 

 examined by them showed a minimum of 96 and a maximum 

 of 154 heart sounds. In one foetus fluctuations from 116 to 

 140 were observed. 



Harms says, in reference to the examinations of Saake : 

 "I have practiced these examinations repeatedly, but never 

 with positive results." 



According to my experience, the heart-beats of the foetus 

 may be heard now and then in the right abdominal region 

 on auscultation ; nevertheless, in numerous cases with well 

 marked foetal movements on palpation, auscultation remained
