Consequently the question ofrickety pelvic bones is sometimes insep-arable from that of the most severe obstetrical or gynaecological operations. 4. In the upper extremity is noted most often thickening of the epiphyses,which appears usually first at the lower end of the ulna and radius, but whichmay involve both ends of all three of the main arm bones. 5. The lower extremities furnish more pronounced illustrations because uponthem rests the weight of the body so soon as rickety children begin to walk,and because this weight will naturally tend to produce curvatures or other de-.

Sometimes these rachitic bones fracture very easily, in which case one mayassume an early and more complete form of decalcification of the bones.
