This is wonderfully ridiculous. I haven't read this since I was a kid, and Sir Isaac Newton the newt passed me by completely. And let's not forget his companion Mr. Alderman Ptolemy Tortoise, who rejoices in the most delightful name in the whole of Potter. A wee bit of a shame we didn't get to see more of those two - Sir Isaac in particular is one of the rare instances in which I've actually enjoyed a pun. And it has to be said, Potter's illustrations in this one are of an even higher standard than normal... they're just fantastic.
