✦ Synopsis

The methodology for evaluation of the a-effect is examined and it is shown that the two-point analysis method is generally of limited value.

This leads to a re-examination of the effect of solvent on the a-effect.

The a-effect, defined as the positive deviation of an a-nucleophilo (e.g., HOO-, NH*-NH2 etc.) from a Bronsted type (log k vs. pKa) plot, remains one of the most intriguing problems

## Abstract The kinematic α‐effect dynamo problem is investigated in the case of an exterior perfect conductor. It is shown that certain approximate symmetries discovered in the numerical analysis of ROBERTS (1972) are exact for this case. As an illustration, an exact solution is given in a cylindr
