Preface 



generous courtesy with which they have lent 

 me books and supplied latest information, with- 

 out which this little book could never have 

 been written ; also to express my warm gratitude 

 for the invaluable help afforded by the criticisms 

 and suggestions of the kind and able friends who 

 have read my MS. and proofs.
