62 Prof. Rigaud o/i those MSS. In G. Britain., which contain 
tion, I can venture to express, a decided conviction of their be- 
ing independent of each other. This conclusion is not drawn 
merely from the number of various readings, although it is so 
very great, as to be nearly irreconcileable with Wallis’s conjec- 
ture ; but there are other and stronger arguments. Though 
the, lacunae are in general the same, there are some in No. 3. 
which are filled up in No. 9., and vice versa, there are some in 
No. 9. which are filled up in No. 3. ; there are readings in 
No. 9. which are inserted in the margin of No. 3., with Krm an- 
nexed to them, which could not be if No. 3. was only written 
out on the authority of No. 9. There are only a few' of the dia- 
grams in No. 9. and it is by no means clear that these have not 
been inserted by some one subsequent to the original transcrip- 
tion ; whereas the diagrams are complete in No. 3., and it is 
most probable that the text and the figures were written and 
made at the same time. Again ^ the lines are very uneven and 
irregular in No. 9., and in collating, I have sometimes passed 
over one of them, and not fixed my eye on that which immedi- 
ately followed what I had been examining ; from the state of the 
writing this was unavoidable, and yet in no one instance was an 
omission from such a cause detected in No. 3., whilst, on the 
contrary, my oversight was always corrected by the occasion of 
its being found from the text of that manuscript. Many con- 
tractions, likewise, and words of which the writing is nearly un- 
intelligible in No. 9., are only to be made out by reference to 
the analogous passages in No. 3. 
Wallis says, Ex tribus quos Oxoniag habemus Pappi Alex- 
andrini Codd. MSS. (in Bibliotheca Bodleiana uno et duobus 
in Saviliana), &c. but after repeated and diligent search, no 
other traces can be found of any such manuscript in the Bod- 
leian library. None is mentioned in any of the catalogues, none 
appears to have been known to Dr Edward Bernard, who was 
from 1673 to 1691 Savilian Professor of Astronomy, and was 
equalled by very few men of his time, in an extensive knowledge 
of the Oxford manuscripts. There is in the catalogue of English 
and Irish MSS. a list of some of Bernard’s own, which were 
purchased for the Bodleian, among which is “ Pappi Florile- 
gium Mathematicum,” and Harles quotes this as a Greek MS.; 
but the list, in which it is inserted, is entitled “ Libri Graeci, cum
