Remarks on a Passage in the 
dans le Grec <p%,$ an lien de <p%.&P If the original had been 
a work printed with Arabic numerals, I can easily conceive 
how an inversion of the type might have introduced a 6 for 
a 9 ; but I own that I can see no strong resemblance of the * 
and the 9 , which could have been likely to occasion the mistake 
in the transcriber of the Greek; neither do I see any other 
cause which could probably lead to it. Nevertheless such an 
error, if it did exist, might certainly remove some difficulty, 
and is therefore deserving of a more particular examination. 
We are now come to a part of the inquiry, which does not 
admit of solution, without a reference to the original Greek, and 
this, as is well known, has never been printed : a few detached 
passages are inserted in various works ; but the great body of 
what remains of the 2w*f*feu is only accessible to the 
generality of the readers in the Latin translation of Comman- 
dine. We have, however, some manuscripts in Great Britain, 
and I have been able to trace out four, which contain the pas- 
sage under consideration : two of them are in the Savilian Li- 
brary at Oxford ; one is in the British Museum, and the fourth is 
in the Advocate's Library at Edinburgh. The three first I 
have myself carefully examined, and as Dr Brewster has taken 
the trouble of collating the fourth for me, I feel persuaded that 
the genuine text of the original is as follows :

I now subjoin the translation, and as reference has been made 
to the commentary, I have annexed the only two remarks which 
Commandine has made upon the passage. 
“ quoniam sphserge diameter ad djametrum aestivi tro- 
pici potestate eandem habet proportionem, quam 629 ad 529, 
etenim recta linea a centro sphaerae ad centrum tropici ducta, 
iongitucline earn proportionem habet ad semidiametrum tropici, 
quam 10 ad 23 f 1 ), erit sphserge diameter minor quam dupla ( 2 ) 
diametri tropici.”
