*Mém. Acad. Sci. Pétersb.***7**(1854), 539-568. Also to be found in*Oeuvres de P. L. Tchebychef, Volume 1*, 111-143, Chelsea, New York, 1961, from where this paper was scanned. The surprisingly many and varied linkages designed by Chebyshev can all be viewed, in action, at Mechanisms (pointing your cursor at the Russian flag at the upper right corner of that page gives you the opportunity to choose to see the page in English). Each of the many mechanisms shown can be activated by a click; there are plans to provide the detailed comments associated with the animation eventually in English.
