viii PREFACE TO THE REVISED EDITION 



These fresh illustrations will, I think, help to 

 still further elucidate many of the most interest- 

 ing features of the subject. 



I am much indebted to Mr. H. N. Dixon, M.A., 

 for various most helpful suggestions, and for 

 kindly advice on sundry points of doubt and 

 difficulty.
