Our first researches, following here, were made concerning the 
result of the stimulation of the nervefibre taken as such. 
In the work of A. D. Wauuer (Points relating to the WEBER- 
FrecHnerR Law. Brain 1895, pag. 200), we again find the necessary 
data in two Tables, completing each other and representing one 
stimulation-series of one definite nerve (L.c., page 209 and 214). 
From the second of these series we again calculate the most 
probable values for the constants A, B and C, obtaining the results 
communicated in our Table EL. — That we did not make use of all 
numbers of the first and second parts of the series together, may 
be explained by the fact that with the first numbers (magnitude of 
stimulus 1.52—2.32) the galvanometer had no shunt, whilst such 
was the case with the higher magnitudes of stimulus. For this reason 
the strength of the current had evidently risen a little, which beco- 
mes visible also in the curve, this latter showing a slight bent 
upward just at the spot where the shunt begins to act.
