  The self-force of classical electrodynamics on a charged "rigid" body of
radius R is evaluated analytically for the body undergoing a slow (i.e., with a
speed v<<c), slight (i.e., small compared to R), and temporary displacement
from an initial position of rest. The results are relevant to the
Bohr-Rosenfeld analysis of the measurability of the electromagnetic field,
which has been the subject of a recent controversy.
