6. " F." — A small number of heights upon the coast of Kent and Sussex ascertained by myself, 

 from observations with excellent barometers and thermometers by the late Mr. Carey. The 

 lower station in these observations was either the shore itself, (the height of the barometer, below 

 or above the spring-tide high or low water marks, being estimated), — or the drawing-room floors 

 of the houses at Sandgate and Hastings, in which I resided, the height of which above the sea 

 was ascertained by a mean of several observations, sometimes checked by comparison with more 

 elevated stations measured directly from the shore, and again from the houses. The variation of 

 the tides at Sandgate was assumed to be the same as at Dover, = 18'30 feet, and at Hastings, 

 = 21*50 feet; which Capt. Beaufort, by whom I have been favoured with these numbers, states to 

 be respectively the mean derived from a series of observations at those places, in 1834 and 

 1835.

• It will be found that some of the heights mentioned in the text of the preceding paper, differ from those 

 of the lists here subjoined, having been calculated froman estimated mean level of the sea, instead of the level 

 at low water. The difference is one half the mean variation of the spring-tides at the respective places men- 

 tioned.
