In the orthotopic group the lowest percentage of conformity 
(65,8) is found in the inverted homopleural buds (hom.dv), 
where the exceptions are due entirely to adjustment by rota- 
tion of the limb as a whole. In the superposed buds the sole 
exception is due probably to the same cause. The exceptional

1 Four cases of anomalous reduplication have been omitted from this tabula- 
tion, inasmuch as they cannot be classified either as conforming or as exceptional. 
cases arising after transplantation of half buds have already 
been discussed, and, as pointed out above, there are in this group 
of experiments obvious disturbing factors which might readily 
account for the exceptions. Taking the experiments as a whole, 
90.9 per cent conform and 9.1 per cent are exceptional, but if 
allowance is made for the difference in the number of experiments 
in each class, assuming that each is a fair sample of what would
