In the present edition I have put this book into what must be (for some
time at least) its permanent form, making such additions and alterations as
seemed necessary.
If I had any opportunity of teaching the language, I should no doubt have
been able to introduce many other improvements; as it is, I have had to
rely mainly on the suggestions and corrections kindly sent to me by various
teachers and students who have used this book, among whom my especial
thanks are due to the Rev. W. F. Moulton, of Cambridge, and Mr. C. Stoffel,
of Amsterdam.
