Nature Cryptograms Set 64

5 cryptograms to solve with a pencil. Each letter of the quote has been swapped for another letter, and the same swap holds all the way through.

20 pt ciphertext — the size a newspaper puzzle page never gives you. 26 pt ciphertext with wide letter spacing and room to write. Both sizes print on US Letter with the answer key on its own page.
