If a speech of some length has to be committed
to memory, it will be well to learn it piecemeal,
since there is nothing so bad for the memory as being
overburdened. But the sections into which we divide
it for this purpose should not be very short: otherwise
they will be too many in number, and will break up
and distract the memory. I am not, however, prepared to recommend any definite length; it will depend on the natural limits of the passage concerned,
unless, indeed, it be so long as itself to require subdivision.
