I think the lectures too valuable, too full of prolonged historic research and thought to live only one day in the columns of a daily newspaper. Even if they were designed "to adorn a tale or point a moral" of the great race to which you belong, whose history commenced with Abraham and will end with that of the human race, still the history of that race was (and is) so intimately interlaced with the history of the other races for the intervening centuries, that the lectures are in part, so much the history of the other races, that they can be read and studied by all men without prejudice or animosity. One thing is certain, you have in the lectures divested history of much of its dry and useless details, and make it a thrilling romance of facts, presented in the simplest and purest Anglo-Saxon language. I know not how others view the lectures, only speak this for myself--no library is complete without the History of the Jewish race, and no history of that race for the period covered, is more comprehensive, truthful and impartial than that presented in these lectures. I think the book would find a ready sale in all thinking, reading communities. Very Truly Yours, THOS. T. CRITTENDEN. LETTER FROM ARNOLD KREKEL, Judge of the U. S. Court, Western District of Missouri. KANSAS CITY, MO, APRIL 2, 1886. RABBI JOSEPH KRAUSKOPF. MY DEAR SIR:--Having attended a number of your lectures on "THE HISTORY OF THE JEWS AND MOORS IN SPAIN," and read such as I did not hear, allow me to give expression to my views regarding the same. Aside from the interest the student of history must always feel in that part of history of which your lectures treat, the manner of treatment specially interested me. Relating historical facts, too often becomes dry and irksome, and it requires more than ordinary skill of presentation to make the subject interesting and attractive. In this you have fully succeeded by interweaving with the facts those matters which enliven the picture. A knowledge of the social condition of a people, and the relation to which they stand to their age, enables us to judge of their worth and the influence they exercised. Your lectures, as a whole, presented a life-breathing social picture of the times and people, and as the civilization of Europe was largely effected by the Jews and Moors, their history embraces to a large extent the history of civilization, and thereby acquires an interest not limited to the people and countries of which your lectures give so interesting an account. A publication in permanent form of your lectures would advance our knowledge of that part of history to which we have always looked for instruction and guidance, and I hope you may find a way of accomplishing this object. Very Respectfully,
