My colleague, Bailly, has brought forward the following objections
against the use of mechanical tractors in labor:
1. These tractors substitute blind force for that of the sentient guiding
hand.
2. They act in only one direction, and do not allow us to change the
traction line according to the change in the pelvic axis; consequently ob-
lique force is applied to the pelvic walls, which, from mechanical princi-
ples, results in loss of direct force.
3. Mechanical tractors interfere with lateral movements of the forceps.
4. They may slip from the head before the accoucheur knows it; and,
if a force of 17 to 18 pounds is being exerted, what may not happen to
the maternal parts ?
5. If manual traction be sufficient to bring down the head through a
contracted pelvis, whenever this is at all possible, what scope or necessity
is there for mechanical tractions?

6. The time requisite for the introduction of these instruments must
add to the maternal suffering.
7. Facts have proved that not only are mechanical tractions dangerous
for the mother, but that further the very foetal lesions which they aim to
prevent are more frequent than after the use of the ordinary forceps.
Although the modifications of Pros and of Poullet have negatived cer-
tain of the above objections, the others are still valid, and we are in per-
