ment of the placenta over the os-uter?, and not accompanied 
by efficient contractions. 
Third. In puerperal convulsions, in which action is mor- 
bid, and misplaced, and speedy delivery becomes neces- 
sary. 
Fourth. In lingering labour, connected either with the 
death of the child, or owing to a cessation of contraction, 
the os-uteri being sufficiently dilated, and the other soft parts 
properly relaxed. ‘This is its most important use, as it is 
here capable, in all cases, of superseding the employment 
both of the forceps and vectis, instruments, which, previous 
to the discovery of the powers of the Clavus, were not un- 
frequently necessary, but could seldom be used without 
ra injury, either to the mother, or child, and usually to

Fifth. In retention of the placenta, from deficency of con- 
traction, it is in general, if not always, capable of superse- 
ding the introduction of the hand. 
Sixth. In subjects liable to hemorrhage after delivery, 
from laxity and deficiency of contraction, this effect may be 
entirely prevented by the exhibition of a suitable quantity 
of the Clavus fifteen or thirty minutes previous to the time, 
when the labour would otherwise have terminated sponta- 
neously. 
Seventh. It may even be employed with advantage after 
delivery, to restrain the hoemorrhage, and moderate the ex- 
he lochial discharge, which results from laxity, and de- 
ility. - 
In too early a stage of labour, before the os-uteri is suffi- 
ciently dilated, and when there is much rigidity of the other 
soft parts, or when there is any malconformation, or a pre- 
sentation that requires changing, the Clavus seldom pro- 
duces any benefit, but in general, greatly increases the suf- 
ferings of the mother, retards her ultimate recovery, and 
most commonly causes the death of the chi
