Figure 15. R. G. Harrison (1921) establishment of embryo symmetry

Illustrations from a paper by R. G. Harrison (1921) on the establishment of symmetry within the embryo. Limb primordia were transplanted in various orientations to the flank region or to the normal position of the limb. This series of illustrations shows an embryo in which a left limb bud was implanted into the same location after being rotated 180°. Figures 49 & 50 are dorsal and lateral views at 4 days, 51 & 52 at 7 days, 53 & 54 at 10 days, and 55 a dorsal view at 17 days after the operation. Duplication of distal limb parts occurred.
