"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.
