A’ A”, with depressed ; B, with high standing promontory (A’ ventral view ; A” and B, 
median longitudinal sections). In A” the highest point of the iliac crest almost reaches 
the level of the upper edge of the penultimate lumbar vertebra (/.7v.)._ In B, on the 
contrary (which is the original condition, and that still found in children), the upper 
edge of the last lumbar vertebra (/.v.) is hardly reached. C’ C”, pelvis with double 
promontory, caused by assimilation of the last lumbar vertebra with the sacrum (OC, 
median longitudinal section; C”, ventral view). In the latter the appearances are as 
if the pelvis had shifted forward along the vertebral column. (After Froriep.)
