All figures are taken from preparations of Mauthner's cell. 



The photomicrographs were not retouched at all. An achromatic Zeiss ocular 

 no. 4 and a Zeiss oil-immersion yo were used. In figures 1 and 8 the length of 

 bellows was 100 cm. and in all the others it was 60 cm. The figures 11, 12, 13, 14, 

 and 15 were drawn using the Abbe camera lucida with slight rotation of the mi- 

 crometer screw. (Apochromatic Zeiss ocular no. 4, oil-immersion yV, tube length 

 20 cm.) In those drawings except 12 and 13 the glia structure is presented in a 

 gray, and the nervous structure in a dark color. It is to be added here that figure 

 7 came from a fatigue preparation.
