From the foregoing we may conclude that our law prevails also 
for the nerve as an excitable organ. 
Already in this place it is of importance however, to point out 
the fact that in nature generally only the first ascending part of 
the curve may be considered normal. This fact is made evident by 
the last of the tables published in my former essay, showing that 
with magnitudes of stimulus, sufficient to make the muscle contract 
and even to compel it to the maximum-contraction, the manner in 
which stimulus and effect were related for the nerve could be 
represented with absolute accuracy by a linear function of the 
first degree. 
We may admit therefore that practically the nerve is a purely 
transmissive organ, giving within the limits of practical use a faithful 
transmission of the stimulus as perceived by it. 
I only have to recall to mind the fact that the minimum per- 
ception of stimulus by the nerve in Table X of my former essay 
began with 1.40989 units. Only when the stimulus was increased
