Positionsof the feet. Fig. 25. 



— Most accoucheurs 

 enumerate four posi- 

 tions forfoot ling presen- 

 tations, viz. : 1st. Heels 

 behind the left acetabu- 

 lum, loins in front and 

 to the left. 2d. Heels 

 behind right acetabu- 

 lum, loins forward and 

 to the right. 3d. Heels 

 behind the pubis, loins 

 directly in front. 4th. 

 Heels to the promon- 

 tory of the sacrum. 

 There are others who 

 enumerate six, corre- 

 sponding with vertex 

 positions, and others 

 again as many as eight, 



corresponding with those of the sacrum mentioned in the beginning 

 of this article. 



Following the arrange- Fig. 26. 



ment adopted in relation 

 to breech presentations, 

 we enumerate but two, 

 viz. : a calcaneo- anterior, 

 and a calcaneo-posterior. 

 1st. When the heel is di- 

 rected forwards and the 

 toes backwards. 2d. 

 When the heel is back- 

 wards and the toes for- 

 wards. The former is the 

 more frequent, and both 

 correspond to the two 

 classes of breech presen- 

 tations. (Fig. 26.) 



The positions of the 

 knees, have also the same 

 varieties, the anterior 

 parts of the leg corres- 

 ponding to the sacrum 

 and the vertex ; and as 

 they are commonly con- 

 verted into footling cases, 

 they do not require a separate description. (Fig. 25.)
