Because this book is based on sigma-ring instead of sigma-algebra although in many modern textbooks this is a default setting, I think this hypothesis should be mentioned.

Adios to Winter Bash Finite-dimensional vector spacesby P. There are, for instance, sound mmeasure reasons for using the terms "lattice" and "ring" for certain classes of sets-reasons which are more cogent than the similarities that caused Hausdorff to use "ring" and "field.
