In conclusion, I gratefully acknowledge the valuable assist- 
ance which I have constantly received from the late Mr. W. 
Wilson, whose friendship it was my privilege to enjoy for many 
years, and who, at all times, was most willing to give me his opinion 
in any cases of difficulty. I have also been under similar obligations 
to the late Mr. G. E. Hunt, of Manchester. My friend and colleague 
in the Cybele Hibernica," Mr. A. G. More, has kindly aided me in 
revising the proof-sheets for the press.
