The present volume is a reprint of that issued in 1912 with the title, "Science from an Easy Chair: Second Series." It consists, like its predecessors, of chapters originally published by me in the Daily Telegraph, which I have revised and illustrated by a large number of drawings. In order to render the issue of the present cheap edition possible, it has been found necessary to restrict its size a little by the omission of chapters dealing with Glaciers, Ferns and Fern-seed, and the history of the Sea-squirts or Ascidians, which are contained in the original larger book. My hope is that this collection of papers, "about a number of things," may meet with as kind a reception from my readers as that which they have accorded to its predecessors.
