NOTES TO BOOK XVII. 



(T.) p. 451. MULLEB (Manual of Physiology, B. in. 

 Sect. 1. Chap, iii,) speaks of Dr. Wilson Philip's assertion 

 that the nerves of the stomach being cut, and a galvanic 

 current kept up in them, digestion is still accomplished. 

 He states that he and other physiologists have repeated 

 such experiments on an extensive scale, and have found no 

 effect of this kind. 



(u.) p. 468. I regret extremely that, in the first edi- 

 tion, I expressed myself in such a manner, with regard to 

 the discovery here spoken of, as to give rise to a complaint 

 on the part of Sir Charles Bell's friends, that I had done 

 injustice to that eminent physiologist. When I wrote the 

 passage, I was not aware of the relative position of the 

 parties, and of the discussion which the history of the dis- 

 covery had already occasioned in the physiological world. 

 Perhaps no one who had not watched, with professional 

 interest, the gradual progress of the doctrine in the minds 

 of contemporary physiologists, could exactly appreciate the 

 merits of the different parties concerned. As authority 

 for the expressions which I have now used in the text, 1 

 will mention Mullers Manual of Physiology, (4th edition, 

 1844.) In Book HI. Section 2. Chap, i., "On the Nerves 

 of Sensation and Motion," Miiller says, " Charles Bell was 

 the first who had the ingenious thought that the posterior 

 roots of the nerves of the spine those which are furnished 

 with a ganglion govern sensation only ; that the anterior 

 roots are appointed for motion, and that the primitive
