Analysis of Envoi

Now don't go and say you'd a dim
Idea of these stories before,
For I've frankly confessed them from Grimm,
The monarch of magical lore:

And if, by repeating, I took
Your time, I will candidly vow
This moral (the last in the book)
Has never been published till now!

The Moral: The skeleton's Grimm,
But I have supplied the apparel,
So it's fifty per cent, of it Him,
And it's fifty per cent. of it Carryl.
But still (from the personal severing,
For it isn't my nature to grump,)
I acknowledge a measure of Levering
Levering-ed the whole of the lump!
