vi PREFACE 



movement, the history of which has never yet been con- 

 secutively written down in full, or subjected as a whole 

 to searching criticism, there must probably be many 

 errors of detail, which can hardly be avoided under such 

 circumstances. I have endeavoured to minimise them 

 as far as possible. For those which may have escaped 

 my own scrutiny I must trust both for correction and 

 for indulgence to the kindness of my readers.
