An Obfervation

THe Obfervcrs, imploying a Telefcope of 21 Foot, faw the 
Vhi\ttSaturny2iS 'tis reprefented by Fig.U. the Globe in 
the midle mamfcftly appearing both above and below beyond 
the Ovale ofhisAnfes; which was hardly difcernable the laft 
year. 
They meafur d divers ways the Inclination of the Great Dia- 
miter of the Ovale to the E^«4/^r,which (Inclination) was tound 
c p dcgrees^alchough at that time it (hould not be but 
c ! degrees, according to what M. Hugens hath affii m'd in 
I erne of Satftrn,viz. that the Plan of the Ring, which en- 
\ :he Globe of this Planet, is inclin'd to the Plan of the 
EcUfftqtte but 2 3 deg, 30. m. But this laft Obfervation and other 
like ones of this and the precedent Year being more exadi, and 
made at a time more proper for meafuring that obliquity^ than 
were thofe, which had formerly ferved for a foundation to deter- 
mine it', M.Hagem finds, that, inftcadof 23. deg, 30. the 
Angle of the plans of the Ring and of the Ecliptique muft be of 
31. deg, or thereabouts and that being fo;, that not oncly the 
Shape, which Saturn hath at prefcnt, but alfo all thofe^that have 
been noted fince the true ones were obferved, do perfedlly agree 
with the Hypothefts of the King and particularly that of 16^4.

As to the round Phafts of Saturny that Change of the4nclina- 
tioojwhich was juft now fpoken of, cannot alter the time of it but 
very little or nothing-, fo that MMugens ftill exfpeds this Ap- 
parancein 1671, when in the Summer ®f that Year SaturismW 
begin to loofe his there being then to remain onely the 
Globe in the Midle-, and will not recover them but about a 
year
