Notes to the preceding paper; length-to-length transmission as the basis of conduction.

After the publication of the preceding paper (1), I found a mistake in eq. (2) and another in deriving eq. (3) from (2), to my great sorrow. The eq. (2) as an approximate expression of Px should have been (1) The basic idea was dPx=-x/k' adx, in other words, that the potential contributed to the point X (the point y=0, fig.1 of the preceding paper) by a small active region dx at x, is proportional to dx. ƒ¿ is the proportionality factor which was dropped in the original treatment, by mistake. For x= • ‡; Px=Vƒ¿k'. In actuality, the transverse current at X will increase gradually with x to attain a certain definite value in the end, as long as the active membrane resistance is not zero. In proportion to this, Px will increase and attain almost V itself at x= • ‡ in case the active membrane resistance is very small as compared to the resting. Hence,
