PLATE XXL 



Fig. I. A projection of the trigemino-facial ganglionic complex of Gadus 

 morrhua upon the sagittal plane, as seen from the left side, x 28. To simplify 

 the diagram the motor component is omitted and also the sympathetic ganglia 

 and nerves. The general cutaneous fibers in the r. oticus and in the outer buc- 

 calibranch are omitted. The relations of the geniculate ganglion cephalad to 

 the supra- and infra-orbital trunks are indicated diagrammatically. Compare 

 the transections on Plate XXII. The peripheral relations of the lateralis fibers 

 in the r. lateralis accessorius are doubtful. In all other cases the diagram 

 expresses observed relations only. 



The heavy black outline indicates the position of the brain. 

 Acustico-lateral system, brown.
