AUXILIARIES IN THE STUDY OF 

 MECHANICAL OBSTETRICS. 



The young veterinarian in the beginning of his practice 

 meets with many difficulties. Nobody expects and demands 

 that he should be an experienced practitioner. He certainly 

 is not yet an expert in practical obstetrics, and here the adage 

 " practice makes perfect " holds true. Of course the basis for 

 it is laid at college, so he may not be embarrassed when called 

 to an obstetrical case. Instruction only cannot school him to 

 such an extent that he directs a case of dystokia with as much 

 dexterity and ease as a common surgical operation, for instance, 

 tracheotomy. Nevertheless, the college may assist him a great 

 deal in this respect, of decided value later ; as by the exercises 

 on the phantom. 



THE OBSTETRICAL PHANTOM. 



Pelviarium is an imitation of the uterus, pelvis and vagina. 

 It serves to recognize and adjust abnormal presentation as in 

 embryotomy. 



The phantom of repositions (fig. 69) consists of the skeleton 

 of a cow or mare in the standing posture. For the sake of 

 greater solidity, iron rods are passed through the vertebral 

 column and underneath the vertebrsB, resting anteriorly upon 

 two rods standing obliquely and posteriori}' upon an iron 

 tripod. Heavy band iron is placed along the linea innoni- 

 inata and symphysis, the same along the costal cartilages. 

 The abdominal wall is made of leather; the latter can be 

 removed. 



The uterus is made of calf's leather, tapered to fit the 

 vagina. On the side of the uterus is a flap through which the 

 calf is introduced. This flap can be closed.
