246. In table IX the values of P/S= ig/a)-\lsin (/> tan with their 

 corresponding logarithms, are tabulated for each degree of from 

 to 89°, when a is the speed, nio, of the principal lunar semidiurnal 

 component, in radians per second. From table II, paragraph 75, 

 the value of mo, in degrees per hour, is 28° .9841. Its value in radians 

 per second is then (28.9841/3600) (7r/180) = 0.000,140,52. This
