this and form 452. Items (1) to (6) are obtained from values given in 
form 244. Item (7) is obtained from table 7, using items (2) and (3) as 
arguments, and item (8) is obtained from table 9, using item (3) as 
argument. Items (9) to (11) are obtained after the rest of the form 
has been filled out. 
314. The log F for each of the listed constituents, except L, and M, 
and those for which the logarithm is given as zero, may be obtained 
from table 12, using item (2) as the argument. For constituents 
L, and M, 
Log F(L,) =log F(M,)+item (7) (448) 
Log F(M,)=log F(O,) +item (8) (449) 
If the tidal series analyzed was observed between the years 1900 
and 2000, the log F(L2) and log F(M,) may be taken directly from
