menced the discussion upon them in a subsequent part of the 
volume. In that portion of my work, it has recently been dis- 
covered that there is an unfortunate misprint of certain intervening 
computed quantities, between Sir Isaac’s original data, and my 
final deduction from them ; some erroneous slip of paper having 
apparently got introduced into the MS. finally sent to the printer. 
I acknowledge that there is such an error, thank those cordially 
who have discovered it ; and have already rescinded it from the 
volume by printing it as an error in a list of errata, of which list I 
place a bundle of examples on the table, so that any member who has 
a copy of “ Life and Work,” may supply himself with this addition. 
A very little attention in collating and comparing, would have 
indicated to the Proceedings author that these intermediate figures, 
as they are printed in the 2d vol. of my “ Life and Work,” p. 
458, are simply misprinted : for, they are neither correctly derivable 
from the original quantities, nor is the following mean derived 
from them. But he has chosen rather to suppress the fact of my 
having given, in the same volume, Sir Isaac Newton’s original 
numbers, and given them correctly and completely, to the extent 
of several pages ; omits Sir Isaac’s statement that he looked on his 
one chosen and adopted quantity as temporary, — parades in Pro- 
ceedings , p. 258, my misprinted intermediate figures, as if they were 
all important original ones ; and glories in pointing out that the 
mean put by me underneath them, is not the correct mean of those 
numbers. Of course it is not ; because it was derived from other 
numbers. And as both that final mean of mine is rightly printed, 
as intended, and the original quantities are also correctly printed, — 
what occasion was there for bringing up this accidental misprint of 
some intervening figures so very prominently, and alluding to it 
as something radically subversive of the whole theory of the G-reat

Pyramid ? 
To assist those who may try to ascertain, I subjoin, in a note, a 
description of the numerical particulars of the case, prepared origi- 
nally for the errata list in “ Life and Work ; ”* and now I pass on 
to the consideration of the next principal section. 
* Sir Isaac Newton's Numbers for the Length of the Sacred Cubit of the Hebrews. 
At p. 458, vol. ii. of Life and Work at the Great Pyramid , there is an unfor- 
tunate misprinting of the calculated numbers representing in British inches,
