what happens in chapter 5?

Professor Liedenbrock is positive that the Icelandic manuscriptit is written in Runic, so he begins to work on breaking the code, but is unable to decipher what it says. Then he figures out there's a name in the first few pages that tranlates to an important Icelandic alchemist, who lived in the 16th Century. The name was Arne Saknussemm. Seeing that the manuscript must be written in Latin (Saknussemm was fluent in the language), the Professor figures out that it contains what might be a route to the center of the earth. Chapter Five ends with the Professor asking for his trunk to be packed for the journey.
