What are the terms of the contract signing ?

Before the time comes to sign the contract, Faustus has misgivings, but he puts them aside. Mephostophilis returns, and Faustus signs away his soul, writing with his own blood. The words "Homo fuge" ("Fly, man) appear on his arm, and Faustus is seized by fear. Mephostophilis distracts him with a dance of devils. Faustus requests a wife, a demand Mephostophilis denies, but he does give Faustus books full of knowledge.
