Indications for Version.—Version may be per-formed in any case of head presentation in which speedydelivery becomes necessary, in the interest of eithermother or child, before the head has passed the brim,*or in arrest of a head presentation at the brim of a nor-mal pelvis by inertia uteri or excessive size of the is the preferable operation when a brow or a posterior.

It is the only con-servative operation which is possible in transverse pres-entations. Contra-indications.—Version should never be per-formed in a justo-minor pelvis, upon the rirst of twins(unless transverse), or upon a dead child, unless undervery favorable circumstances. It is impossible if thehead is impacted. Choice between Version and Forceps.—The dis-cussion of the relative advantages of
