In preparing the following pages I have been chiefly indebted for the materials of the earlier chapters to some MS. notes by my late uncle, Mr. William Cairns. These were originally written for Professor MacEwen when he was preparing his admirable Life and Letters of John Cairns, D.D. LL.D. They are very full and very interesting, and I have made free use of them.

To Dr. MacEwen's book I cannot sufficiently express my obligations. He has put so much relating to Principal Cairns into an absolutely final form, that he seems to have left no alternative to those who come after him between passing over in silence what he has so well said and reproducing it almost in his words. It is probable, therefore, that students of the Life and Letters—and there are many who, like Mr. Andrew Lang with Lockhart's Life of Scott, "make it their breviary "—will detect some echoes of its sentences in this little book. Still, I have tried to look at the subject from my own point of view, and to work it out in my own way; while, if I have borrowed anything directly, I trust that I have made due acknowledgment in the proper place.

Among those whom I have to thank for kind assistance, I desire specially to mention my father, the Rev. David Cairns, the last surviving member of the household at Dunglass, who has taken a constant interest in the progress of the book, and has supplied me with many reminiscences and suggestions. To my brother the Rev. D.S. Cairns, Ayton, I am indebted for most valuable help in regard to many points, especially that dealt with at the close of Chapter VI.; and I also owe much to the suggestions of my friends the Rev. P. Wilson and the Rev. R. Glaister. For help in revising the proofs I have to thank the Rev. J.M. Connor and my brother the Rev. W.T. Cairns.
