In the infant pelvis the unfinished ilia are short,rounded, very patulous, and without any foss. The brim of thepelvis looks almost directly forward, in consequence of the pubislying so much below the sacrum, that a line passing horizontallybackwards from the symphysis pubis would pass through theextremity of the coccyx. The antero-posterior measurement ofthe brim is the longest, the transverse is the shortest, just as inthe lower animals. There is scarcely any pelvic cavity; theischia are closed in; and consequently the tubers approximate,and the arch of the pubis is contracted : hence the transversemeasurement of the outlet is very small, the antero-posteriorequally long, and, being almost parallel with that of the brim,it resembles in this respect also the pelvis of quadrupeds. Fromthis extreme, a gradual change goes forward, until the pelvis.
