because he bad some tolerable linear, but no angular , apparatus : 
— and I freely left him with the linear duty, which I foresaw could 
only be approximate, and, in so far, could be as well done by him 
as by me — while I undertook the angular work ; and which, if I had 
not undertaken, then and there, would not have been attended to at 
all, on that occasion of the sockets being opened up. Moreover, my 
time had become so limited that I could not have undertaken both 
species of measurement ; nay, even with the angular measures alone, 
I was not only occupied with them from the time of the sockets 
being discovered, to the moment of my being removed from the 
Pyramid by the Egyptian government, — and then had to leave 
some of those angular quantities very imperfectly observed and 
some not at all, — but Mr Inglis kindly assisted me in what I was 
enabled to accomplish ; as fully described and gratefully acknow- 
ledged in “ Life and Work,” vol. i. And it was not until after 
I had left the Pyramid altogether, that Mr Inglis found time 
to complete his promised linear part of the measure, or the lengths, 
and levellings, from socket to socket. He laboured at them, as 
I believe, very conscientiously, and sent me the results by a special 
messenger when I was leaving Egypt for Scotland : and by me, 
after having obtained Mr Aiton’s consent and approval, they have 
been published to the world in the name of that gentleman and 
his assistant. 
What credit there is, therefore, in those linear measures — the 
first that had ever been taken from socket to socket round all four 
of the sides of the Pyramid — belongs, worthily to Messrs Aiton 
and Inglis, and no one can take it from them. But what discredit 
is now sought to be attached to them by a certain party, because 
their measures are not of the exalted accuracy of a well-measured 
trigonometrical survey base-line, is not theirs (Messrs Aiton and 
Inglis) — much less is it mine, as the Proceedings' author tries to 
insinuate — but it is the necessary consequence, which I expected 
from the first, of the measurement being attempted on the strength 
of No. 1 only having been performed, and no attention paid to 
Nos. 2 and 3 both of my p. 340, and of my representation, from 
the first moment of arriving in Egypt, to His Highness the Vice- 
roy.
