From A Space Child's Mother Goose by Frederick Windsor, illustrated by Marian Perry. Simon and Schuster, 1958
(This is available in reprint, on Amazon. I highly recommend it to those that love technology, art, parodies, and vocabulary.)
The colloid and the crystalloid
Were fighting just in jest.
The colloid called the crystalloid
Some called them physical and some called them chemic,
And some thought the whole affair was slightly academic.
Moves awkwardly at best.
Its feet are long, uneven, and retractile.
Who hunts this beast in rhythm
Must take his meter withm,
And still may only bag a ptero-dactyl.
I'm a great fan of the illustrations in the book, done by an artist with a technical ink pen, I'm sure. (rapidiograph, etc)
It's all 1950's high tech stuff, and still topical today.
