George Orwell, in his essay Some Thoughts on the Common Toad
, wrote, "The toad, unlike the skylark and the primrose, has never had much of a boost from poets." One exception is Ralph Hodgson, Lines
No pitted toad behind a stone
But hoards some secret grace;
The meanest slug with midnight gone
Has left a silver trace.
No dullest eyes to beauty blind,
Uplifted to the beast,
But prove some kin with angel kind,
Though lowliest and least.
In the penultimate line, "kind" is a noun (with "angel kind" cf. "mankind"), not an adjective.
