The refult of my experiments upon the 
mufcles, recalled, however, my attention 
to this objedt. 
Having proved by a great number of 
experiments, that the movements do not 
fail to take place when one touches the 
coating of the fpine, or the fpine itfelf, 
at the part where it is uncoated, or the 
origin of the nerves j I wifhed to know, 
if by laying bare the nerves along the
