236 Mr. costard’s ‘Tranjlation of 
pinquo difiantise maximae a terra. Deus fcit an calculus 
hie bene lit politus. Tempus refpondet diei 8 Jun. 
an. Chrifti 978. 
Thus far Mr. schultens. And here I mull obferve 
that, according to him as well as curtius, the Sun’s al- 
titude at the beginning was about 56°, or in Arabic nota- 
tion y ; but by computation I make it only about 
47 ° 5 0 * Suppofe it were 47 (/-*}; then where the letters 
are fmall and ill made, y and may ealily be miftaken 
for each other. 
The Sun’s altitude at the end of this eclipfe, according 
to both curtius and schultens, was 26° (J) ; but'by 
calculation I make it a little more than 36° (p ). But 
thefe figures are fo nearly alike that they would eafily 
be miftaken by an ignorant tranferiber, and from a ma- 
nulcript that was ill wrote. 
How schickard, or curtius for him, came to make 
the digits eclipfed 7^ I know not: for in the manufeript, 
as tranllated by schultens for Mr. grischow above, 
we fee they were only 5^ and that fuper calcnlo accura - 
tiore t or as the Arabic Ihould have been tranllated', juxfa 
calculum accuratiorem. The meaning of which, I fup- 
pofe, is that ebn younes had found' by calculation that 
the digits eclipfed would be 5I, and that at the time his 
calculation agreed with his obfervation; as indeed itdid, 
for
