 is certain that when the action of the liver is sympathetically in- 

 creased, so that it pours out more bile, the portion of peritoneum that 

 covers it does not throw out more serum, because it is not affected by 

 it. It is the same of the kidney, the pancreas, etc. 3d. For the same 

 reason the gastric organs upon which the peritoneum is spread do 

 not partake of the sympathetic influences that it experiences. I shall 

 say as much of the lungs in relation to the pleura, the brain in rela- 

 tion to the tunica arachnoides, the heart to the pericardium, etc. 4th. 

 It is undeniable that in all sympathetic convulsions, the fleshy texture 

 alone is affected, and that the tendinous is not so at all. 5th. What 

 has the fibrous membrane of the testicles in common with the sym- 

 pathies of its peculiar texture? 6th. No doubt a number of sym- 

 pathetic pains that we refer to the bones, are seated exclusively in 

 the marrow. 



I could cite many other examples to prove, that it is not this or 

 that organ that sympathizes as a whole, but only this or that texture 

 in the organs ; besides, this an immediate consequence of the nature 

 of sympathies. In fact the sympathies are but aberrations of the 

 vital properties ; now these properties vary according to each texture ; 

 the sympathies of these textures then would do the same.
