To Professor W. Rhys Roberts, of Leeds University, I owe a debt of gratitude which I can never adequately repay; not only for the kindness with which he encouraged and advised me in the course of my preliminary studies of the Theognidean question (1901-4), but also for many helpful suggestions made during the preparation of this edition; and finally for his assistance in correcting the proofs when the book was passing through the press.<br><br>I am also indebted for valuable assistance to my colleague Mr. W. H. Porter and to Mr. J. MacInnes of Manchester University.
