SYMMETRY IX TRANSPLANTED LIMBS 119 
APPENDIX 
HISTORIES OF SELECTED INDIVIDUAL CASES 
A. Heterotopic trans'plantations 
1. Homopleural, dorsodorsal 
Experiment Tr. E. I48. May 4, 1915. Right liml^ bud to right 
flank; orientation normal. 
May 5. Healed except for two small oval areas. 
May 8. Transplanted bud points caudallv like nomial limb. 
May 12. Sketch (fig. 5). 
May 15. Transplanted liml) slightly bidigitate — not so long or as 
far differentiated as normal. 
May 21. Transplanted liml) has grown considerably, normal pos- 
ture; two digits well marked, third appearing. 
Ma3" 2G. Third and fourth digits show more plainlj' than in sketch 
made on JNIay 24 (fig. 6). 
June 1. Limb a normal right (homopleural) limb in normal i^osture 
(fig. 7). 
Experiment Tr. E. 182. April 13, 1916. Right limb bud to right 
flank; orientation normal. 
April 14. Perfectly healed. 
April 16. Tranplanted bud as large as normal, points caudallv. 
April 25. Not so large as normal, points dorsocaudalh^ 
May 1. Much shorter than normal. Points caudally, arising from 
a ridge-like prominence on side of bod^^ 
May 7. Two distinct digits and trace of third. A new bud is 
growing from l)ase anterolaterall3\ 
May 15. Original limb (the posterior one in fig. 9) has three distinct 
digits and beginning of fourth, shows elbow bend. It is a, normal 
right (homopleural) in nearly normal posture, though it sticks out 
stiffly to side. The two limbs are entireh' separate from their origin. 
The anterior member, which is the reduplicating one, shows onh' a 
faint trace of the third digit on the anterior border. 
Experiment Tr. E. 210. May 10, 1916. Right limb bud to right 
flank; orientation normal. 
]May 11. Healed except for small area of uncovered yolk at caudal 
border of wound. 
^lay 15. Transplanted bud somewhat smaller than normal, points 
in same direction. 
]\Iay 18. Posture as of normal right limb. At base a rounded 
prominence which points head ward. 
I\Iay 22. The prominence has become a reduplicating limb, showing 
first trace of digits. 
May 28. Both limbs well developed. Original is longer and is a 
right (homopleural) with three digits and faint trace of fom'th. Redup- 
licating member branches from other at elbov>' and is a mirror image of 
latter, except that it is less advanced in development.
