During the summer a study of some of the most important industries at the Dusseldorf Exposition proved useful; but somewhat later other excursions had a more direct personal interest; for within a few hours of each other came two unexpected communications: one from the president of Yale University, commissioning me to represent my Alma Mater at the tercentenary of the Bodleian at Oxford; the other from the University of St. Andrews, inviting me to the installation of Mr. Andrew Carnegie as lord rector of that institution; and both these I accepted. The celebration at Oxford was in every way interesting to me; but I may say frankly that of all things which gave me pleasure, the foremost was the speech of presentation, in the Sheldonian Theatre, when the doctorate of civil law was conferred upon me. The first feature in this speech, assigning the reasons for conferring the degree, was a most kindly reference to my part in establishing the Arbitration Tribunal at the International Conference of The Hague; and this, of course, was gratifying. But the second half of the speech touched me more nearly; for it was a friendly appreciation of my book regarding the historical relations between science and theology in Christendom. This was a surprise indeed! Years before, when writing this book, I had said to myself, "This ends all prospect of friendly recognition of any work I may ever do, so far as the universities and academies of the world are concerned. But so be it; what I believe I will say." And now, suddenly, unexpectedly, came recognition and commendation in that great and ancient center of religious thought and sentiment, once so reactionary, where, within my memory, even a man like Edward Everett was harshly treated for his inability to accept the shibboleths of orthodoxy. This reviving of old and beginning of new friendships, with the hearty hospitality lavished upon us from all sides, left delightful remembrances. Several times, during the previous fifty years, I had visited Oxford and been cordially welcomed; but this greeting surpassed all others.
