In the preparation of my book I have received much kindness, and I should especially like to thank Mr Philip Spencer Gregory, of Lincoln’s Inn, Barrister-at-Law, late Fellow of King’s College, Cambridge, for the help which he as a representative of the family was able to give me, and also for his very interesting ‘Records of the Family of Gregory.’ My thanks are also due to Professor Campbell Fraser for personal introduction to sources of information, to Mr Turner, Savilian Professor of Astronomy in the University of Oxford, and to Mr Henry Johnstone of the Edinburgh Academy and Mr R. S. Rait, Fellow of New College, Oxford, who have read my proofs. I must also record my debt of gratitude to the Editors for the great kindness and courtesy they have shown to me.
