Xll PREFACE. 



R. Henry Hew, Professor J. P. Sheldon, Mr. James Sinclair, 

 and Mr Sanders Spencer. Additional obligations are recorded 

 in the text. 



The proof-sheets of the entire work have been read by Mr. 

 F. R Armytage, M.A. (Balliol College, Oxford), Mr. A. E. 

 Brooke-Hunt, B. A. (Trinity College, Cambridge), Mr, Maiden, 

 Professor Sheldon, and Mr. David Young, to all of whom my 

 thanks are tendered. Other gentlemen have been good enough 

 to examine the proof-sheets of parts of the treatise bearing 

 upon subjects with which they possess special acquaintance. 



It may be added that, throughout the volume, no effort has 

 been lacking to make the text a faithful mirror of progress 



and a reliable record of modern practice.
