ERNEST ESCLANGON: Clocks indicating simul taneously mean solar time and sidereal time. It is possible to have a master clock, showing mean solar time, connected by a train of wheels to another clock showing sidereal time. The choice of the number of teeth on the connecting wheel work is worked out and a number of examples given showing the gear train and the corresponding error in seconds after 100 years starting with 1938.
