Note. — In fig. 14 the directing line from ‘Hnt.f\ myloliy. n.” should 
pass directly upwards to the group of fibres on the periphery of the 
nerve, cf. fig. 15.

Fig. 1. — Right masseter nerve : roots of left fifth cranial nerve 
divided thirty days previously. 
Fig. 2. — Left masseter nerve : roots of left fifth cranial neiwe divided 
thirty days previously. 
Fig. 3. — Left anterior digastric nerve, close to muscle : roots of fifth 
cranial nerve divided thirty days previously.
