[Philadelphia: 1913]. 8" x 105". Two horizontal folds, else Very Good. Rudolph Blankenburg, the Mayor of Philadelphia, wrote an article for the Scientific American entitled, "The Municipal Need of Technically Trained Men" which was published in Vol. 108, April 12, 1913, pp. 341-343. This letter evidently pertains to that article. The recipient of Blankenburg's letter, John Ritchie, Jr., was one of the organizers of the Boston Scientific Society. He and Seth Carlo Chandler, Jr., devised a telegraphic code that substantially improved the transmission of numerical scientific data. We do not warrant the genuineness of the signature. Item #23324
