prof. Rigaud on those MSS. in G, Britain^ which contain 
they appeared to be the same ; and, from having recently colla- 
ted the whole of No. 3., I was very familiar with the characters 
in which it is written. The final letters are frequently extended 
in the same forms in both manuscripts, and there is a particular 
mark at the end of the paragraphs, which is made in the same 
manner in both of them ; the letters are of the same size ; there 
is the same number of lines (30) in each page ; and the length 
of the lines, as well as the intervals between them, is the same 
in both. Pages 49, 253, containing books iii, iv, v, vi, and the 
beginning of vii, are by a second hand. A small part then fol- 
lows, in a third hand, at the bottom of page 253, and top of 
page 254 ; but this is loosely written, and evidently is an inser- 
tion of what was wanted between the second and last parts, for 
it does not extend to the bottom of page 254 ; and page 255, 
to page 481 , contain the latter part of book vii, and the whole 
of book viii. These are written in a fourth hand, apparently 
older than the rest ; and from page 487, to page 514, is a collec- 
tion of diagrams, hut they extend no farther than the 45th pro- 
position of the 4th book. 
The whole is on paper in folio, and in good preservation, al- 
though the red ink, in some places, is faded. There is a curious 
memorandum at the end of the 8th book :

This is written in a different hand from any in the text of the 
work, so that it does not appear that any part of the copy was 
made by Baroci himself ; and how old it was when he employed 
himself in examining and correcting it, is hardly now to be as- 
certained. It is remarkable that he talks of hosce octo libros,”
