presented; in others, it is not. Here, as in the last 
presentation, it must be decided at once, the position 
of the head and neck, and, as it is rather common to 
have a fore and a hind foot presented, it is necessary 
to be particular in distinguishing the one from the other. 
Cord all the limbs presented, using cords of different 
colors for fore and hind limbs, and if the head is in the 
passage, cord it also; then, when this is done, with a 
repeller, push into the uterus the extremities not 
wanted, and apply gentle traction to the limbs to be 
deliverd first. In this, as in the previous case, the 
lumbo-sacral presentation should be adopted, if both 
extremities can be reached. If, however, all the limbs 
are firmly wedged in the passage, then a portion of both 
fore and hind limbs must be removed, at the knee, 
or further up. Sometimes it is then impossible to 
push back the foetus; cut into the abdomen and remove 
the organs, when it will be possible to return either 
extremity into the uterus, and complete delivery. 
DORSO-LU MBAR. 
In this, it is found that labor has been present for a 
time, and still no foetus presented. On examination 
per vagina, instead of the feet of the fcetus, we find 
some portion of the vertebral column presented, and 
the head of the fcetus is found in the right or left 
flank, all four feet pointing in an anterior direction. 
Before delivery is attempted, it must be ascertained 
definitely the position of the head and neck, and of all 
the limbs; then decide whether the fcetus has to be 
delivered in the anterior or posterior presentation.
