Many specimens in my cabinet, and in theWistar Museum, attest the accuracy of this In my own experiments upon the chicken, the bones uniformly re-sumed their original position as soon as the restraining force wasremoved, unless a fracture occurred, and this notwithstanding thebones were bent quite abruptly and to an angle of twenty-five de-grees. Certainly, if the bones of children may be bent during life andbe made to retain this position without a fracture, then the same thingmight be done upon the bones of children recently dead, and by suc-cessful experiments, this long agitated question might be easily andforever put
