Note 10 — Chapter XXVII

This subject is discussed and some account of the chemical nature of protoplasm given in my book, "Science from an Easy Chair" (Methuen, 1910), which consists of a first series of papers similar to those which are collected in the present volume as a "Second Series." The chapters in the earlier volume to which I wish to direct the reader's attention are those entitled "The Universal Structure of Living Things," "Protoplasm, Life and Death," "Chemistry and Protoplasm," "The Simplest Living Things."
