ERRATA.

The errata are put immediately before the body of the work, or at the end

of it. They should consist only of such corrections as are _indispensably

necessary_, without noticing any defects in the punctuation, unless where

the sense is perverted. It is strongly to be wished that works could

be produced perfectly free from errors; but this is almost a vain hope

while imperfection clings to humanity, and while every form is exposed to

accident and every additional proof may be productive of fresh error.
