terniinalis of tlio Vertebrates gaiiglioii-cells are scattered along (he 

 whole course of the nerve, then one is compelled to grant to the 

 terminal nerve (he character of a nerve of an invertebrated animal. 

 Nevertheless Ihis type of nerve is obvionsly another than that of 

 the olfactory nerve. 



In connection with the preceding remarks I shoidd like to point 

 to the fact that xAmphioxns, whose nervous system is generally 

 compared with that of vertebrated animals, possesses in its sensorj- 

 nerves the nerves of a true Invertebrate. All or most of them contain 

 processes of conducting sense-cells as these cells are scattered about 

 the whole body, and moreover tnost of the sensory nerves are 

 accompanied by dis|)ersed ganglion-cells. Therefore spinal ganglia 

 are lacking.
