and loins corresponding to the pubis of the mother, while the limbs are 

 toAvards the sacrum, against which they are more or less pressed. This 

 is sometimes termed the second posterior position. 



3. Left Lumho-ilial Position.— The foetus is lying on its left flank, its 

 croup and loins opposite the ascending branch of the left ilium of the 

 female, and the limbs towards the right flank, where they must be sought 

 for if they do not present* in the pelvis. 



4. Right Ltimho-ilial Position. — This is exactly the reverse of the pre- 

 ceding position. 



XIII. Dorso-Lumbar Presentation. 



Here the foetus is presented across or transverse, and it may lie on one 

 or other of its sides, its head towards one of the maternal flanks, and the 

 body curved like that of a dog asleep. In this we have two distinct po- 

 sitions, according as the foetus lies on one side or the other. But it may 

 also assume a third and almost vertical position— the croup on the floor 

 of the abdomen of the mother, and the creature in the attitude of a dog 

 sitting. 



The important consideration in these three positions is related to the 

 situation or direction of the head ; as, if this is known, we may easily infer 

 that of the other parts of its body, and thus appreciate the indications for 

 delivery to be followed in this pathological presentation. According to 

 the direction of the head, the three following positions are described: 



1. Right Cephalo-ilial Position. — The foetus is on its right side, which 

 rests more or less directly on the abdominal walls of the mother, the head 

 in the right flank, the croup towards the left flank, the body more or less 

 curved, and the dorso-lumbar region towards the pelvis, in which it 

 presents. 



2. Left Cephalo-ilial Position. — This is the reverse of the preceding. 



3. Cephola-sacral Position. — In this position the foetus is presented by 

 the back, and in an almost vertical attitude : the croup resting on the 

 floor of the mother's abdomen, the head more or less depressed, and 

 directed forward towards the sacro-lumbar region — the creature being 

 seated, as it were, on the udder of its parent. 



XIV. Sterno-Abdominal Presentation. 



In this presentation the foetus offers the abdomen to the inlet of the 

 pelvis, and on exploration the hand first meets this part, and tAvo or more 

 of the limbs, but always at least a hind and fore one. The head may be 

 found, or it may be out of reach. The sternum and other parts on the 

 lower surface of the body can also be felt.
