Royal Society’s Mufeum, having been lately prefented them 
by that skilful Mathematician Mr. William Jones, F. R, S. 
That he had only one Manufcript of Commen- 
tary, out of the Bodley Library ; and two Greek Copies, from 
the Savilian Study, of Pappus’s Colledions, out of whofo 
7ch Book he took the Lemmata, which ferve as a Comment 
on the more difficult Places of his Author ,• and that he was 
forced to revife and correct the Miftakes and Improprieties 
of the Latin Tranflation of Commandine. 
As to the latter Books, which were only in Arahick, he 
informs us, that he made ufe of the Boddey Txanfcript of 
a Manufcript that is at Leyden, which it felf is a late Co- 
py of that ancient Arahick Book of the Conickt, heretofore 
Gclius's, but fince purchafed by that great Patron of Uni- 
verfal Learning, NarciJJus late Primate of Ireland, who was 
pleafed to favour him fo far as to fend over into England 
this Original Book, whereby he not only amended feveral 
Faults committed by the Copyifts in a double Tranfcrip- 
tion, but was alfo affured that this Arahick Book was a ver- 
bal Tranflation from the Greek; the fame Schemes markc 
with the fame Letters, and the whole Context being the 
fame in the firft four Books of it, as in the Greek Apollo- 
nius This valuable Manufcript, with about 800 others, 
Oriental and Greek, has fince, by the Donation of that moft 
venerable Prelate, made a noble Acceffion to the Bodley Li- 
brary, wherein it is now depofited. It appears by an Epi- 
grapbe at the end, to have been written in the Year of 
Chrift 150;. and to have been a Copy of a Tranflation of 
the Conicks, made fome Ages before by Thehit Ben Corah, 
but ther) newly revifed by that famous Perfian Mathemati- 
cian Nafir-eddin, who flourifh’d about the middle of our 
thirteenth Century. 
Behdes this , the Editor tells us, that on occafion he 
confulted another Arahick Manufcript ( heretofore Ravim’s ) 
of great Antiquity, being an Epitome of the fame Books by 
Ahdolntelec of Schiraz, every where agreeing in the Order 
and Argument with the former, but abridg’d. So that ha- 
ving had thefe Helps, he is in hopes that he has fo far re- 
trieved thofe Three Books of Apollonius, that the Lofs of the 
Greek Text may henceforth be lefs lamented.
