iv PREFACE
below; but wherever even a hinfhas been borrowed, the
writer to whom Obligation has been thus incurred will
always be found referred to in the notes. There are many
such references, especially to the publications of H. Diels;
but the mainstay of the whole work has been the actual
text of Plato, Aristotle, and Theophrastus. A list of the
Greek passages explained or discussed has been added at
the end. In some—perhaps most—of these the points
raised are of no great interest to scholars, but there is at
least one exception; and it is hoped that what has been
Said on Arist. 45a'' 17-24 may be of some value.
The author wishes to thank the Delegates of the Claren­
don Press for undertaking the publication of this work.
His thanks are also due to the Press Reader and Staff for
their great care and accuracy. It remains for him, in con-
clusion, to express his deep gratitude to Mr. W. D. Ross,
Fellow and Tutor of Oriel College, Oxford, for kindly
reading the proofs, and making acute suggestions from
which much profit has been derived. He is indebted
to Mr. Ross for having drawn his attention to Diels'
palaeographical correction of Arist. 985'' 17, mentioned
on p. 37, n. %.
