In conclusion, I have to thank the illustrious author and the publisher for permission to use Das arabische Reich und sein Sturz as has been done. The proof-sheets have been most carefully read by my friend Mr James Robson, M.A., Moncrieff Manse, Alloa, who has also verified the dates and other figures, and to whom any freedom from errors of detail which the work possesses is due. The sheets have also been read through and the Index checked and corrected by M. G. W. Lastly, I have to express my indebtedness to the printers for the extreme care with which a difficult type has been set up. The plan of Bagdad is reproduced by the kind permission of the Delegates of the Clarendon Press, from Le Strange's Baghdad.
