To Mohammedans the author owes more than a word of apology. A stranger and a sojourner among them, he has ventured on an exposition of their domestic griefs, and has occasionally touched the ark of their religion with what will seem to them a profane hand; but his motive has been throughout a pure one, and he trusts that they will pardon him in virtue of the sympathy with them which must be apparent in every line that he has written.
