“…Many opinions could be quoted both in favour of and against this method of inducing labour. A good sample in British and American literature is contained in the writings of Drew Smythe (1931), Drew Smythe andThompson (1937), FitzGibbon (1931), Tennent (1938), Guttmacher and Douglas (I 931), Jackson (1934), Wilson (1934), andGoodwin (1937). Drew Smythe (1931) recommends induction of premature labour by artificial rupture of the membranes for all cases in which the foetus presents by the vertex.…”
