   note: "it so chanced that, not long after the accession of
         the house of hanover, some of the brown, that is the
         german or norway, rats, were first brought over to this
         country in some timber as is said; and being much
         stronger than the black, or, till then, the common,
         rats, they in many places quite extirpated the latter.
         the word both the noun and the verb to rat was first,
         as we have seen, leveled at the converts to the
         government of george the first, but has by degrees
         obtained a wider meaning, and come to be applied to any
         sudden and mercenary change in politics." --lord mahon.
