MR. LUBBOCK ON THE TIDES.

moon's transit, as theory suggests, the equation of time for the middle of January 

 being + 10"*, then 1^ 39"* should be subtracted from 1^ 44™'8, the semimenstrual in- 

 equality corresponding to the moon's transit at 50™. This gives — 2*8 to be «« dded 

 to — 3. I therefore formed the following Table, which gives the quantity to be added 

 for a given equation of time, in order to reduce the Table B. to what it should be, 

 having the argument of the moon's transit in apparent time. 



Table C. 



By interpolation I then formed the following Table, taking the equation of time for 

 the middle of the month. 



Table D. 



Adding the figures in the preceding Table to those in Table B., neglecting fractions 

 of a minute, I obtained the following.
