ROULET, Paul. Remarks on Notation. [N.p., 1873]. 8 pp. + folding plate. Original printed wrappers, split along the spine. Author's ink note to front wrapper.

Roulet reconceived numerical notation as a recursively organized hierarchical information structure. His folding table presents a systematic field architecture for representing arbitrarily large numbers, employing powers-of-two growth, recursive subdivision, and fixed positional relationships. Although intended as a reform of numerical notation rather than a computational method, the work exhibits striking conceptual parallels with later hierarchical data structures, database schemas, and information organization used in modern computing. As a bonus thought experiment we applied Roulet's process to Elon Musk's estimated networth-- see image for results. (ChatGPT AI Assistant generously provided the summation & example.)

Separately-issued pamphlet of a paper by Paul Roulet, Principal of the Waverly Institute, on the subject of notation. The author's own note on the front wrapper supplies the origin: "Taken from the proceedings of the University Convocation held in Albany, N.Y. August 1, 2, 3, 1871, page 110. Paul Roulet, Lebanon, Mo.?" — establishing this as an offprint (or author's separate) drawn from the printed Proceedings of the University Convocation of the State of New York, where the paper was read at the August 1871 session and printed at p. 110. The convocation was the annual assembly of the officers of colleges and academies under the visitation of the Regents of the University of the State of New York; papers of pedagogical and scientific interest were read and issued in the annual Proceedings. Roulet's Waverly Institute was the academy at Waverly (Tioga Co.), N.Y., later absorbed into the village school system — an institution of exactly the type represented at Convocation.
