FOREWORD ix 



these may be of interest or service, I have included 

 papers upon them. 



In conclusion I should like to express my 

 gratitude to the proprietors of the Field, for 

 permission to reprint a number of papers con- 

 tributed by me to that journal over the signature 

 " Seaforth and Soforth," which come within the 

 scope of the work ; and to Mr. H. T. Sheringham, 

 for his invaluable advice and assistance in the 

 arrangement of these papers. 



G. E. M. SKUES.
