XXVIl] SKIN. SENSORY NERVE ENDINGS 215 



Sensory nerve endings. 



The endings in mucous membranes, and in tactile corpuscles 

 are best seen in preparations made by the methylene blue 

 injection method. Cp. p. 321. 



For other gold chloride methods cp. p. 318. The lateral line 

 of a fish may be taken for nerve eminences. 



In birds, Grandr/s corpuscles and other forms of sensory 

 nerve endings are numerous in the waxy skin at the edge of the 

 beak, in the palate and in the tongue (best perhaps in the back 

 of the tongue). In the duckling, a transverse section of the 

 posterior part of the beak including the palate may be made.
