Dr. W.J. Holland, Director Emeritus Carnegie Museum Pittsburg, Pa. Dear Dr. Holland: During my stay at Pittsburg I had the pleasure to take your and Dr. Bolivar's pictures. I add two copies and would be glad to send you more if you will order so. When at Washington I had the opportunity to see our Mexican Ambassador Mr. Tellex and told him about the "Diplodocus" affair. He was very interested int he matter and told me that the fault lays with Prof. Alfonso Herrera who did not answer him, but promised me to write anew to the Mexican Authorities. It seems that he has done so, as the Mexican Newspapers brought emphatically notes about the big monster Mexico will get from Mrs. Carnegie. With kindest regards, Dr. Alfonso Dampf
