In these older embryos the limbs appeared in cross section as a small group of mesenchyme - like cells lying within the somatic mesoblast. The extirpation was made by burning out the limb-region, on the right side of the body with a hot needle, so that the cells of the somatopleure, from which the limb would naturally be derived, were removed leaving the yolk exposed beneath. In order to leave no room for doubt that the injury had included the limb-rudiment, the.
