4. The gradual decrease in the function of the limbs as they | 
become implanted more and more remote from the normal limb 
region seems to be directly correlated with the segmental nerve 
supply, the function of the limbs bemg more perfect when 
innervated from the limb level of the cord. 
5. Transplanted limbs receiving less and less innervation from 
the normal limb level of the cord show a corresponding decrease 
in their ability to exhibit movements codrdinated with those of 
the intact limb of the opposite side. 
6. The gradual loss of function of limbs, as they become trans- 
planted farther and farther away from the normal situation, is 
attributed to increased defective connections within the central 
nervous system rather than to a corresponding decrease in 
effective peripheral innervation and structural deficiencies of the 
limb and the shoulder-girdle. 
7. In general, as the distance between the normal position and 
the transplanted limb is increased, a corresponding increase oc- 
curs in the time required for initial limb reflexes to appear. 
Limbs in which the appearance of initial reflexes is considerably 
delayed are less apt to attain perfect function. 
8. The number of segments occupied by the transplanted 
limb rudiment does not determine the number of segmental 
nerves contributing innervation to the limb. 
9. The results of the experiments suggest that the transplanted 
limb rudiment exerts a guiding influence on the segmental nerve 
contribution and determines the path taken by the nerves 
effecting innervation of the limb. The positive reaction toward 
this influence appears to be greater in the nerves coming from 
the normal limb level of the cord. 
10. Regardless of the segmental nerve contribution, the archi- 
tecture of the nerve distribution within the transplanted limb is 
exactly the same as that in the normal limb. These results 
corroborate those of Braus (’04, ’05) and Harrison (’07). 
11. Gradually increasing the distance between the normal 
position and the transplanted limb brings about a gradual 
increase in the number of reduplicated appendages.
