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 wide meaning, and come to be applied to any sudden
and mercenary change in politics." Lord Mahon. Bamboo rat (Zoöl.),
