MR. LUBBOCK ON THE TIDES. 



Table XLII. 



Showing 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 her Horizontal Parallax. 



Table XLIII. 



Showing the Difference in the Height of High Water and the Mean Height (Co- 

 lumn B. Table XXIV.) for every minute of the Moon's Horizontal Parallax. 



The following Tables may be used in predicting the phenomena of the tides, with 

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



For the Time of High Water at the London Docks. 



Table III., column A., containing the semimenstrual inequality + a constant, 

 which is again inserted here for the convenience of reference. 



Table XLIV. containing the correction for the moon's parallax. 



Table XLV. containing the correction for the moon's declination. 



The last two Tables have been obtained from Tables XL. and XLIL, by removing 

 arbitrarily the irregularities which those Tables present. 



Table XLVI., formed by arbitrary alterations from Table G., p. 148, gives the cor- 

 rection for the calendar months. 



To the result obtained must be added the equation of time, in order to have the 

 time of high water sought in mean time.
