Art. Y.-^Some Account of those Manuscripts in Great Britain^ 
which contam the GreeJc Text (f the Mathematical Collections 
of Pappus. By S. P. Rigaud, Esq. M. A. F. R. S. Savili- 
an Professor of Geometry, and Professor of Experimental 
Philosophy in the University of Oxford, &c. &c. Communi- 
ed by the Author, (Concluded from p. 64.) 
There is a manuscript at Edinburgh, for a description of 
which I must be indebted to Dr Trail, who gives a full detail 
of all the particulars of it in his life of Dr Robert Simson. He 
says that it contains five books of Pappus, viz. the 3d, 4th, 
5th, 6th and 8th ; but unfortunately the 7th, the most valuable 
portion of the work, is wanting.” 
This MS. was purchased at Paris in 1748, by Dr James 
Moor, then Greek Professor at Glasgow, from Mr De Mairan, 
of the Academy of Sciences ; and on the first page of it is writ- 
ten D’Ortons de Mairan, probably by his own hand. De Mai- 
ran had informed Dr Moor that it had belonged to Bullialdus ; 
and on that account Dr Simson, who had it for some time in his 
possession, and took many notes from it, calls it Codex Bullial- 
di. like the other MSS. of Pappus, it abounds with errors ; 
but Dr Simson obtained from it several improved readings and 
corrections, which he has remarked in his copy of Commandine’s 
Translation. Some of them are curious and important, and all of 
them merit the attention of any future editor of that work. 
‘‘ Some peculiarities in this MSS. may be mentioned, for the 
satisfaction of those who may be inclined to consult it. 
At the end of the Sd book are five pages of MS., not in 
Commandine’s edition, which contain some variations of the solu- 
tion of the Deliacal problem, in addition to those contained in 
the beginning of that book 
“ * It may be observed, that the Savil MS. No. 3., has a similar addition at the 
, end of the 3d book.” This same additional passage is found also in No, 9, Kol- 
larius likewise describes it in his account of the two Vienna Manuscripts of Pap- 
pus ; and, consequently, it must be in No. 2440. of the French King’s Library, 
from which one of them is copied. It may not be wholly irrelevant to point out 
here a singular oversight of Kollarius, in his description of lxvii, the latter part of
