CHAPTER I. INTRODUCTION, INCLUDING THE AUTHORS METHOD AND THE PLAN 



OF THE RESEARCH. 



IN the Proceedings of the Royal Society, vol. 45, 188i), p. IS (Meeting of November 1, 

 1888), we published a preliminary account of some of the experiments of which the 

 results ;iro now given in full det til.
