Comments on the Linearized Current-Potential Characteristic SIR: Two recent communications ( I , 2) have correctly emphasized the need to be vigilant while employing linearized forms of the rate equation:

Equation 3 is deduced from Equation 5 if ACR ((a - l ) ~ $ q ) ~Eo , a47 and (1 - cy)$r can be neglected.

Two linear versions of Equation 1 have been taken up for discussion ( 2 ) ; they are:

That is, if $7 is small enough, not only ( + v ) ~ , (47)3 etc. ACo are lower-order terms to be abandoned, even "a$r], CO ACR ACo (1 - a)+?, a( ~ ~ 4 etc. 7 ) ~are, in general, lower-order CR CO
