MR. LUBBOCK ON THE TIDES. 149 



The numbers in the last Table are extremely irregular, and leave the correction 

 due to the calendar months subject to much uncertainty. 



The following Tables are subjoined, forming a sequel to those ah-eady printed in 

 the Philosophical Transactions for 1831. 



Table XXII. shows the height of high water at the London Docks, corresponding 

 to the mean time of the moon's transit in each month of the year, from 6565 observa- 

 tions, made between the 1st of January 1808, and the 31st of December 1826 and 

 between opposition and conjunction. 



Table XXIII. is interpolated from Table XXII. 



Table XXIV. gives the mean of Table XXIII. and Table V. 



Table XXV. shows the time and height of high water at the London Docks, cor- 

 responding to the time of the moon's transit for every minute of horizontal parallax, 

 from 5413 observations, made between the 1st of January 1808 and the 31st of De- 

 cember 1826, between opposition and conjunction. 



Tables XXVI. and XXVII. are interpolated from Table XXV. 



Table XXVIII. shows the time and height of high water at the London Docks, 

 corresponding to the time of the moon's transit, and for every three degrees of her de- 

 clination, north and south, from 5424 observations, made between the 1st of January 

 1808 and the 31st of December 1826, between opposition and conjunction. 



Tables XXIX. and XXX. are interpolated from Table XXVIII. 



Table XXXI. shows the difference in the interval between the time of the moon's 

 transit and the time of high water, and the mean interval (Column A. Table III.) for 

 every minute of the moon's horizontal parallax between opposition and conjunction. 



Table XXXII. shows the difference in the height of high water, and the mean height 

 (Column B. Table XXII I.) for every minute of the moon's horizontal parallax, between 

 opposition and conjunction. 



Table XXXIII. shows the difference in the interval between the time of the moon's 

 transit and the time of high water, and the mean interval (Column A. Table III.) for 

 every three degrees of the moon's declination, between opposition and conjunction. 



Table XXXIV. shows the difference in the height of high water, and the mean 

 height (Column B. Table XXIII.) for every three degrees of the moon's declination, 

 between opposition and conjunction. 



Table XXXV. (mean of Tables VII. and XXVI.) shows the interval between the 

 moon's transit and the time of high water at the London Docks for every minute of 

 her horizontal parallax, from 10,812 observations, made between the 1st of January 

 1808 and the 31st of December 1826. 



Table XXXVI. shows the time and height of high water at the London Docks, 

 corresponding to the mean time of the moon's transit for every minute of her hori- 

 zontal parallax, from 10,812 observations, made between the 1st of January 1808 

 and 31st of December 1826. 



Table XXXVII. is interpolated from Table XXXVI.
