and, if we admit it to be an interpolation, there will remain no 
reason for supposing that Pappus meant to refer to his own 
work. Tec is the well known expression for the Elements

uniformly given to each of his own books is o'Woi'YeJYifi^ and at the

Of these eight books, it is very probable that no entire copy 
is at present in existence : certainly there is none in our own 
country. In the Catalogus Librorum MSS., Angliae et Hiber- 
nioe, published at Oxford in 1698, there is mention made of two 
manuscripts in the Saviiian Library in that University. They are 
marked 6550 : 3, and 6556 : 9, the larger numbers referring to the 
general enumeration, and the smaller (3. and 9.) to that of the 
Saviiian Manuscripts. These have been about 200 years in Ox- 
ford ; for they appear in the original ‘‘ Catalogue indented be- 
tweene the Universitye and Sir Henrie Savile, contayning the 
names of such bookes as the said Sir Henrye Savile hath be- 
queathed to the University, for the use chiefly of the msithema- 
tical readers.” This catalogue is signed by Sir H. Savile him- 
self, and there can therefore be no doubt of the manuscripts 
being older at least than 1620. This is indeed a late date, but 
neither of the books bears any marks of high antiquity. 
No. 3. is very well written on paper, and the ink is cleat* 
throughout ; the volume is in excellent preservation, and in the 
original binding. It contains the Greek text of the 3d, 4th, 5th, 
6th, 7th and 8th Books of the Mathematical Collections, with 
the diagrams for these books, very neatly drawn, after which 
are inserted some works of Theodosius and Autolycus. The 
whole is written undoubtedly by the same hand : each line is re- 
gular, each page is bounded by an ample margin, and the extre- 
mities of the writing are as even as if they had been set olF with 
a ruler. The titles of the several books, those of the leading 
divisions of the work, many of the initial letters, and the num- 
bers of the propositions in the margin, are written with red ink.
