The third and last volume of his History of Modern Astro- 
nomy was almost, if not wholly, finished at the time of his death, 
as appears from the following extract of a letter addressed to 
Professor Moll : u I have almost finished the 3d volume, which 
will be entitled the Astronomy of the Eighteenth Century , and 
which will terminate with the labours of Maskelyne. It will 
embrace in a separate book the History of the Measurement of 
the Earth, from that of 1700 to the time when the volume shall 
appear. In these three volumes, I have told only what is true, 
and nothing which is not capable of being proved ; but I have 
at the same time told the whole truth. I anticipate that I shall 
be considered as sometimes severe ; but I have taken my reso- 
lution. In ordinary life, I listen to every thing, without dis- 
puting with any person ; but I have made up my mind, after a 
long and severe examination, and I wish to discharge a duty to my 
conscience. My work attacks no living author ; and if any one 
cavils with me, it must be in favour of some of the illustrious 
dead, whose errors he is anxious to cover, or whose merit he 
wishes to exaggerate, by attributing to him what he has not 
done, and what he has borrowed without acknowledgment from 
others.”
