Thechanges in the skull are of the same nature as those in the long bones,viz., dystrophic. (b) The long bones in the most characteristic types are diaphysis is short and thick, so as to present little or no medul-lary canal; the epiphyses are mostly cartilaginous and enlarged, andthe whole bone is bent, the normal curve being exaggerated. Thepicture thus presented is that of a dwarf with short extremities(micromelia). There are forms of chondrodystrophia without anymarked shortening of the extremities, but rather of the lower partof the trunk (Klebs, Kaufmann). Morbid Anatomy.—There are no changes in any of the internal PLATE XI.
