determining that there was no response in the external popliteal the two 
popliteals (sciatic) crushed with haemostat and tied together with three 
eat-gut ligatures one-quarter inch apart. On August 19 (114 days 
after fusion), same nerves exposed, and firm neuroma found at place of 
fusion. Faradic stimulation of external popliteal showed flexion of 
toes, but no extension. Internal popliteal responded normally. On 
November 6 (193 days after fusion) similar responses and animal sac- 
rificed. No clinical improvement noted.
