 <[ui en modifient vraiment les points essentials, en 1844 (The nervous system of the human 

 body as explained in series of papers read before the Royal Society of London, 1844, 

 i'edit.). 



II resulte de la que, beaucoup mieux que GALIEN, LAMARCK et AL. WALKER, CH. BELL a 

 pressenti, et partiellement demontre, pour les nerfs de la face tout au moins, qu'il y a 

 des fonctions differentes pour les racines anterieures et les racines posterieures, niais 

 que la generalisation et la demonstration formelle de cette loi reviennent entierement 

 a MAGErnuE (1822).
