Monfieur Hugens having examined thefe Appearance^ and 
the Caufe of the differecce from what, he predifred of them^ 
finds not that they are contrary to his Hypoihefis of the Flat 
Ringabout Saturn, by the means of which he exphcatech all 
the Changes of his figure 5 butheefteems, that they will (erre 
to determine^more precifely than could be done hitherto,;he 
feveral Appe^ra ces of this J{pund figure 5 and becaufe he fore- 
feeihj that it will fo appear again within a little time, and at 
the furfheft in December next^ and that the fame will fo con- 
tinue the remaining time of its Appearance, he confiders the 
Return of the ArmSj which do at prefent appear, as a little 
jnterr uptioD of this Round figure ; which would not fo much 
as have been perceived with raidle-fized GlafTc s of 6 or 7 feet, 
like thofe that were ufed by Gahki and Gaj]efidii which Ex- 
perience may verifie, if inftead of Telefcopes of 15 or 20 feet 
long^you employ only foine of thefe fmaller ones, with which 
you are not ^ble to difcern thefe Arms becaufe of their tenuityj, 
and that they are but faintly illuminated by the Sun beams , 
which do more obliquely fall upon the fiat furface of tte 
Ring.

next Summer, after his Conjundtion with the Sun, with Arms 
hke thofe he hath now 5 in which he amends his Predidion 
o( A, 1659 5 having feen by thefe laft Obfervations (as he was 
already aware of it in his Syjieme^) that this Round appear» 
ance is to be defined to a lefs num.ber of degrees than he had 
done,in refped: of great Tekfcopes.
