Plate XLI.

Masculine Pelvis.



PLATE XLII.

Represents the peculiar deformity most frequently produced by Mollites Ossium. The different parts are stretched out as it were, and crushed inwards toward each other. The size of each strait is diminished in nearly every diameter, and the whole form is very unfavorable to delivery. This is sometimes called a cordiform pelvis. Observe the difference between it and the standard one.
