PLATE XCIII. 



FIG. 24o".-Sketch to illustrate the relations of the 

 ganglionic cord in the visceral cavity of the frog. 

 The teptum ciitcrrxe magnae having been divided on 

 the right side, the right kidney is turned over towards 

 the left, so as to expose the parts concealed by it, viz., 

 the aorta and the gangliouic cord of the same side. 

 The stomach and the first coil of intestine are also 

 turned over, so that the posterior surface of the 

 former organ is presented. In this way the origin of 

 the mesenteric artery from the junction of the right 

 and left aorts? is brought into view. On its surface 

 nervous filaments, which spring from 'the ganglionic 

 cord, may be traced. These (nervi mesenterici) com- 

 bine to form a plexus with similar filaments from 

 the corresponding ganglion of the Other side. (See fig. 

 295.) I, Liver; rl, right lung; *, stomach; k, kidney.

 with the nerves in relation with them. (After Ludwig,
