The measurements ofthese pelves are not always below the normal standard; they may con-tinue to grow, although they have not developed. The proportionatemeasurements of the various diameters will then be as in the infant, andthe antero-posterior diameter may be longer, or as long, as the transverse,the ischia comparatively near each other, and the pubic arch a form of pelvis will interfere with the mechanism of delivery,and unusual difficulty in labor will be experienced. Difficulties from a Fig. Adult Pelvis retaining its Infantile Type. similar cause may be expected in very young girls. Here, however,there is reason to hope that as age advances the pelvis will develop andsubsequent labors be more easy. Masculine or Funnel-shaped Pelvis.—The masculine or funnel-shapedpelvis owes its name to its approximation to the type of the male bones are thicker and stouter than usual, the conjugate diameter ofthe brim longer, and the whole cavity rendered deeper and narrower atits lower part by the nearness of the ischial tuberosities. It is generallymet with in strong, muscular women following laborious occupations,and Dr. Barnes, from his experience in the Royal Maternity Charity,says that it chiefly occurs in weavers in the neighborhood of BetlmalGreen, who spend most of their time in the sitting posture.
