The duration of each mean solar month is 30d. 10h. 31m. 248., and during this period in addition to one whole revolution, the mean moon increases her distance from mean sun, in measurement by 10,000ths of circle by, (or in other words the monthly increase of a=) 307-352623726.
N.B.-These values of a agreo generally with Professor Jacobi's values above (Vol. XI, p. 164). The apparent differences are due to two causes; (i) The present estimate of the sum of the greatest equations of moon and sun is about 0-4 greater than that of Professor Jacobi. (ii) The values here stated for the beginn.
of centuries 38 to 42 are for mean sunrise on Saturdays, while his aro for mean sunrise on the following Sundays.
