x PREFACE TO THE FIRST FRENCH EDITION 



I wish to take this opportunity of expressing my thanks to those of my 

 Teachers to whom I am indebted for my instruction in the subject ; I 

 have drawn largely upon them and should this book be received with some 

 favour I shall be not unmindful of those to whom the credit is due.
