SYMMETRY IN TRANSPLANTED LIMBS 121 
May 29. Limb points as before. Two well-marked digits which 
are slight^ irregular. Probably no reduplication. 
June 5. Limb sticks out to side almost horizontally; first two 
digits short, third distinct, fourth barely indicated. Reduplicating 
hand attached to radial border of the same limb and pointing vent rally 
has two digits. 
N. B. It is uncertain whether this member developed out of the 
bud noted on May 25. 
3. Heteropleural, dorsodorsal 
Experiment Tr. E. 227. May 19, 1916. Right limb bud to left side, 
dorsodorsal. 
May 20. Well healed. 
May 23. Transplanted bud points dorso-anteriorly and is more 
massive than normal. 
May 26. Grafted limb about same length as normal; points ante- 
riorly and laterallv, scarcely dorsally (figs. 20 and 21 drawn one day 
later). 
June 2. Grafted limb now reaches to the axilla of the normal limb; 
trace of third digit (fig. 22, made day before). 
June 5. Limb a normal right (is not reversed), pointing antero- 
laterally, crossing the normal limb on the medial surface (fig. 23). 
Experiment Tr. E. 107. April 9, 1913. Right fore limb to left 
side, dorsodorsal orientation. Diameter of transplanted bud 3 somites 
(3 to 5). 
April 10. Crescentic uncovered area of 3'olk ventral to bud, which 
otherwise is well healed in. 
April 14. Grafted bud shows indications of pointing headward. 
April 21. Limb growing, pointing anteriorly exactly in reversed 
position. No digitations yet. 
April 28. Limb is clearly a right; third digit now plain, with slight 
nodule to indicate fourth. 
May 5. Possibly slight motility of grafted limb. It is now seen to 
be a perfect right, sticking out sharply to side, upper arm is inclined 
dorso-anteriorly, fore arm slightly posteriorly; palmar surface of hand 
ventro-anterior (figs. 24 and 25). 
Experiment Tr. E. 127. May 12, 1914. Right limb bud to left 
side, dorsodorsal orientation; diameter of bud 3 somites. 
May 13. Healing perfect. 
May 16. Transplanted bud growing well with slight indication of 
pointing anteriorly. 
May 18. Limb points distinctly anteriorly. 
May 22. Two digits show; a reduplicating bud is growing out from 
base of graft. 
June 1. The primary limb now shows fourth digit and is a perfect 
right (fig. 26, PR) . The redupHcating member {D U) is a left, though not 
quite so far along in its development. The primary limb now points 
laterally and posteriorly Avith its ulnar border headward.
