he thought, that he faw alfo the Light continued from without, 
although very (lender. But he acknowledges, that he could ne- 
ver yet precifely determine, by how much the largenefs of the 
Ring was bigger than the Diameter of Saturn’s Body. As for the 
proportion of the Length to the Breadth, he affirms, to have al- 
waies eftimated it to be two and a half, or very neer fo ; and to 
have found in his Obfervations , that in January Iaft, one time, the 
length of Saturn was i z Lines, and the breadth 5-. Another time, 
the length was 1 2. Lines, and the breadth 4. and this by a peculi- 
ar method of his own. But yet he acknowleges alfo, that fome^ 
times he hath eftimated it as 7, to 3. and at other times as 1 3. to 
5. and that if there do not happen ^change in the magnitude of 
the Ring (as it is not likely there does) that muft needs proceed 
from the Conftitutionof the air, or oftheGlafs’s having more or 
lefs Aperture, or from the difficulty of making an exatft eftimate 
of their proportions.. However it is not much wide (faith he) of 
two and an half, although Campani make the length of the 
Ring but double to its breadth. 
Monfieur Auzgut believes, that he was one of the firft that have 
well obferved this flladow of Saturn's Body upon its Rings 
which he affirms happened two years fince $ when, obferving in 
Jtdy fior the firft time, with a Tele (cope of 11. and then another of 
27. foot, he perceived, that the Angle of the obfeure (pace on the 
tight fide beneath, was bigger and wider, than the three other 
Angles , and that fome interruption appeared there , between the 
Ring, and the Body of Saturn s of which he faith to have given 
notice from that time to all his friends, and in particulars foon 
as conveniently he could, to Monfieur Hugens, 
He confefTeth,thathe hath not had the opportunity of obfer- 
ving Saturn in his Oriental Quadrat ; yet he doubts not, but that 
the Jhadovo appears ©nthe Left-fide , confidering, that the Exu 
fienee of theT^zwg’ can be no longer doubted of, after fo many Ob - 
fervations of the jhadovo caft by Saturn's Body upon it, according 
a,s it muft happen, following "that Hypothecs j there being no 
leafon, why itihould caft the fad Jhadow on one fide, and not 
on the other.
