The information contained in the following pages is no collection of inferences deduced from study. I am bringing to my readers knowledge which I have obtained by favour rather than by effort. It will not be found the less valuable on that account; I venture, on the contrary, to declare that it will be found of incalculably greater value, easily as I have obtained it, than any results in a similar direction which I could possibly have procured by ordinary methods of research, even had I possessed, in the highest degree, that which I make no claim to possess at all - Oriental scholarship.
