This was a surprise, finding M. Bollee's article (Sur une nouvelle machine a calculer) in this 1889 Comptes Rendus, pecking around in that big 10-pound volume looking for something else. It was very easy to miss if you weren't looking for it, just a few pages long in a 1000-page book. But there it was, nestled comfortably in pp 737-739. It these few pages Bollee describes his machine and with particular reference to his innovative approach to direct multipilication--a fine addition (ha!) to the long line of contributions by Babbage and Clement, Scheutz, Wiberg and Grant and Hamann.
