An excellent instru-ment for this class of casesas well as the high ones is thelast model of the Tarnieraxis-traction forceps. Theforceps is applied reversed(inversion of the forceps);namely, with the concavityof the pelvic curve toward the posterior part of the pelvis, and, of course, toward the occiput. Leaving thehandles to take care of themselves,\ traction is made upon the traction rods only, and the swivel connect- ^ ,. \ ing these with the blades will allow of ,. ^ \ spontaneous rotation on the part of ; the head durin^ its descent.
