should state that they are the mean results of two sets of measurements, 

 the first taken by myself in 1839, and the other by Sir Frederick 

 Abbott in 1846. I now give these measurements in detail for

The only way in which 1 can account for the great difference of 5 feet in 

 the height of the lower story between Blunt's measurements taken in 

 1794 and the actual height as it now stands, is by supposing that there 

 must have been an accumulation of rubbish at the foot of the tower 

 which would have diminished the actual height of the basement story. 

 His heights of the second and third stories agree very closely with my 

 measurements, but that of the fourth story is more than 2 feet short 

 of the true height. The height of the fifth story is not given. 



108. In recording Blunt's measurements Mr. Fergusson has I 

 think, made a mistake in excluding the cupola from the ascertained 

 height of 242 feet 6 inches. Blunt distinctly states that the height 

 of the third story was 180 feet, which, deducted from 242-J- will oi ve 

 no less than 62 J feet for the height of the two upper stories. But 

 this height, as we know from present measurements, is Only 25 feet 4 

 inches, plus 22 feet 4 inches, or altogether 47 feet 8 inches, which 

 deducted from 62i feet leaves 14 feet 10 inches unaccounted for. I 

 conclude, therefore, that this must have been the height of the cupola 

 as it stood in A. D. 1794. Accepting this view as correct, the true
