and I am of opinion that if we had a complete plan of the 

 nervous system, showing the whole of the efferent and 

 afferent nerve-fibres and all the intervening cells, with their 

 arborisations, so that the different circuits could be traced, 

 my contention as to condenser-action in the body would be 

 more than amply justified. 



The first of the diagrams to which I have referred is 

 given in the chapter upon the Medulla Oblongata, and is 

 intended to illustrate the origin and relations of the root- 

 fibres of the cranial nerves (Fig. 117). 



There is a further diagram of the efferent fibres only, 

 but no unipolar or storage cell appears. 



The second diagram to which I have alluded is given in 

 the chapter upon the Pons Varolii, and is a plan of the 

 origin of the fifth nerve : 



Fig. 118. 



G, Gasserion ganglion ; a, b, c, three divisions of the nerve ; m'nv, 

 superior motor nucleus ; mnv, principal motor nucleus ; psnv, principal 

 sensory nucleus ; asnv, dnsv, descending sensory nucleus ; dsv, descending 

 root ; cv, c'v, central sensory tracts composed of fibres emanating from 

 the sensory nuclei ; r, plane of the raphe. (After Schafer.)
