Note 148 — Chapter XIII
Reading edition
By some commentators, this hint, given with female subtilty, is explained to mean that their copy-hold, or lease, by which Banquo and his son hold their lives, is not eternal. The more probable meaning is that, if they are cut off, nature will produce no more copies of their race. But in either meaning the hint that she gave was the same, and it included both Banquo and his son.
