AUTHOR'S NOTE 



I AM indebted to the proprietors of the Field 

 for permission to insert extracts from articles 

 I wrote for that paper, and herewith acknow- 

 ledge gratefully the favour granted. 



Except in those few instances where I have 

 thought it best to make extracts as originally 

 printed, all the accounts of runs have been rewritten, 

 but confess that I had to refresh my memory by 

 a perusal of articles which were paid for by the 

 Field.
