Studies and observations of the osteogenesis in the chick embryos were required for the understanding of the human development. We modified the current methods and found an easy method for visualizig the skeletal system of the embryos in various developmental stages. The materials on which we stained the skeletal system were the embryos of stages 27 to 45 by Hamberger and Hamilton(1951). We could easily observe the osteogenesis in these embryos by our modified techique but could not observe the cartilaginous structures.
