Sio Mr. Bell on the nerves which associate the muscles 
Instead of the relations of the vital organs of circulation and 
respiration depending on some supposed influence of the 
sympathetic nerve, they are found to have an appropriate 
system. 
This system of nerves, extricated from the seeming con- 
fusion in which it lay hitherto encumbered, is found to be 
superadded to that of mere feeling and agency, attributes 
common to all animals : through it we see, engrafted as it 
were, and superadded to the original nature, higher powers 
of agency, corresponding to our condition of mental supe- 
riority : these are not the organs of breathing merely, but 
of natural and articulate language also, and adapted to the 
expression of sentiment, in the workings of the countenance 
and of the breast, that is by signs, as well as by words. So 
that the breast becomes the organ of the passions, and bears 
the same relation to the developement of sentiments, as the 
organs of the senses do to the ideas of sense.
