Hence we have, if M" and S" represent, the Lunar and Solar Semidiurnal Coefficients, 
uncorrected for Declination and Parallax, 
2(M"+S")=48. 
2(M"-S")=20. 
M" = 17 inches. 
97 = 0-412 (18) 
Table IX. contains the Times and Lunitidal Intervals of Half-Flood and Half-Ebb, 
determined from Table I., from the moment at which the water-level passed the mean 
height of Tide-level, as noted at foot of column 4, for each day.
