Note 1 — PREFACE TO THE SECOND EDITION

This second edition would have been completed several years ago but for the illiberal policy which closes the Reading Room of the British Museum at 7 o’clock and has thus made it practically inaccessible to me except on Saturdays.1 I therefore desire to express my grateful thanks to those friends who have facilitated my labours by the loan of books from the Libraries of the University of Leiden and the University of Utrecht (through the kind offices of Professor Wensinck), and the École des Langues Orientales Vivantes, Paris;—to Mr. J. A. Oldham, editor of The International Review of Missions, I am indebted for the loan of volumes of the Allgemeine Missions-Zeitschrift, a set of which I have been unable to find in London; my thanks are specially due to Dr. F. W. Thomas, who has allowed me to study for lengthy periods (along with other books from the India Office Library) the monumental Annali dell’ Islam by Leone Caetani, Principe di Teano,—a work of inestimable value for the early history of Islam, but unfortunately placed out of the reach of the average scholar by reason of its great cost.
