In performing this task, under the pressure of a virtual obligation to issue the first volume in the first month of the new year, the Editor has relied upon the kindly aid of an able friend, as typographical corrector of the Edinburgh sheets. It is only necessary to add, that he has bracketed all his own notes, so as to assume the responsibility for them ; but his introduc- tions are so separated from those of the translators, that, after the first instance, he has not thought it requisite to suffix his initials to these brief contributions. He regrets that the most important volume of the series is necessarily the experimental one, and comes out under disadvantages from which it may be expected that succeeding issues will be free. May the Lord God of our Fathers bless the undertaking to all my fellow-Christians, and make good to them the promise which was once felicitously chosen for the motto of a similar series of publications : " Yet shall not thy teachers be removed into a comer any more, but thine eyes shall see thy teachers."
