THE VISCERAL EFFERENT DIVISION. 205 



DEMONSTRATION OR LABORATORY WORK. 



1. Review the dissections already made, with especial reference to 

 the viscero-motor rami of the cranial nerves. 



2. Study the spinal accessory nerve in a mammal, either by dissec- 

 tion or in embryos such as the pig. Compare the arrangement of the 

 X and XI roots in a 12 mm. pig embryo with that in a selachian or 

 the frog. 



3. In Golgi or Weigert sections offish or frog brain study the origin 

 of the viscero-motor roots of the cranial nerves.
