Grocott & Ward, comps. Grocott’s Familiar Quotations, 6th ed. 189-?.
Trimmers
Damn’d neuters, in their middle way of steering,
Are neither fish, nor flesh, nor good red-herring:
Nor whigs, nor tories they; nor this, nor that;
Nor birds, nor beasts; but just a kind of bat:
A twilight animal; true to neither cause,
With tory wings, but whiggish teeth and claws.
Dryden.—Epilogue to the Duke of Guise.
