review text: The considerations of the problem, how to generalize or to find another proof of the theorem that the only continuous function for which the Schwarz derivative vanishes everywhere is a linear function, had led the author to some facts concerning summability of trigonometric series and the theorem that \(A^+\) and Abel summability are not comparable.
