a Pajfage in ebn younes. 239 , 
With regard to the time of the oppofition, and the 
Moon’s riling at Cairo, there is very little difficulty; for 
flie role there at 6 h 48' to", and the time of oppofition 
was at 6 51 24' 36". 
The end of this eclipfe there was at y h 54' 26", and 
the time of Sun-fet was at 6 h 47' 5 2". The difference is 
r h 6 / 1 6",. and agrees very well with the maruilcript. 
The paffage, as we have it here in curtius from 
schickard, is very obfcure. For it feems either to mean 
that when the digits eclipfed were the Moon was 26° 
high, or that fhe was 2 6° high when the eclipfe ended. 
But I take the laft to be intended; for the Moon was 
26° high at 7 11 36', and the eclipfe ended, as we faw, at 
7 h 54' 26". 
But when schickard or curtius fay this defectus ad 
Si digitos accrevit , the meaning mull be that they 
amounted only to 5^. But this is not true; for according 
to the manufcript, they were between 8 and 9, and I 
make them about 8|. 
I am apt to fufpect, therefore, that the tranfcriber, 
whoever he was, call his eyes on the Solar eclipfe above, 
where the digits eclipfed are really 5^, and carelefsly fet 
them down to this Lunar eclipfe where they do not be- 
long. And to confirm this conjedture it muff be ob- 
ferved, that after the word Dioclefian under this Lunar 
eclipfe,, in the Arabic follow fix lines, which are a repe- 
tition
