What did Ulrich give Clarisse before her marriage in the novel, The Man Without Qualities II: The Like of It Now Happens?

Clarisse received copies of Friedrich Nietzsche's writings from Ulrich before her marriage to Walter. For readers who do not know, Nietzsche was a rather radical 19th century German philosopher. He was a humanist in that he believed that humans could spiritually evolve and progress without God, particularly in the European Christian sense.
