The book has an ink blot in the cover... no, wait, it's the faint remains of some words...

Uncle is wild with excitement now! This book was owned by Arne Saknussemm, the sixteenth century Icelandic alchemist! Maybe the code is a valuable secret? Or just some fake magic spell? Uncle won't let us eat or sleep until we know what it says! So, should we have another look at the paper? Or get out some helpful books? Or do something else?
