 its croup and /<)/;/,s opposite the asceudinj^ branch of the right iHum of 

 the female, and the hmbs towards the left Hank of the mother, where 

 they must be sought for if they do not present in the pelvis. 



4. Left Lumbo-ilial Position. — This is exactly the reverse of the 

 preceding position. 



5. liiijht Lumho-ilio-sacral Position. — This is intermediate between 

 the lumbo-sacral and the right lumbo-ilial positions, the lumbar region 

 being towards the right ilio-sacral articulation. 



6. Left Liimbo-supra'Coti/loid Position. — This is also intermediate 

 between the lumbo-pubic and left lumbo-ilial position, being the reverse

 of these, and an- accordingly abnormal, while the luniho-ilial, like the 

 dorso-ilial, hold tln' middle place with regard to facilities and diOiculties

Positions in the Dokso-lumhau Pkesentation. — Here the fcctus 

 is presented across or trdn.srcrse, and it may lie on one or other of its 

 sides, its head towards one of the maternal flanks, and the body curved
