              The paper discusses Problems 8 and 88 posed by Stanisław Mazur in the Scottish Book. 
It turns out that negative solutions to both problems are immediate consequences of the results of Peller
 [J. Operator Theory 7 (1982)]. We discuss here some quantitative aspects of Problems 8 and 88 and give answers
  to open problems discussed in a recent paper of Pełczyński and Sukochev in connection with Problem 88.
