 times observe the medulla spinalis to swell 

 out in portions, so as to appear like a series 

 of connected ganglia, as is evident in the 

 preparation which Mr. Hunter has exhibited 

 of that part in the lion. The experiments 

 of M. Le Gallois, show that the nervous 

 influence of portions of the body, corre- 

 sponds with that part of the medulla spina- 

 lis to which their nerves are connected; 

 that it forms a kind of centre from which 

 nervous actions radiate, and to which they 

 tend. Yet according to the view I have 

 exhibited of the nervous functions in the 

 introductory lectures, it appears necessary 

 that such actions should be transmitted to 

 and from the brain in order to commu-

M. Le Gallois seems, h(>wever, to sup- 

 pose, that sensation continues in the me-

 I might be led on to suppose that a duck
