that we have feen the whole SatdUtiam of Saturn out- 
felves. 
'The Subftaiice of thefe Obfervations is as follows. 
Anno 1714 Matt 6. St N about Mid-nighc, Saturn 
being tlienStafionary in ’t? 4°; zy', the Fifth and ouccrmoft 
Satellite was in its fuperiour Conjunift on with the 
Planet, and at the fame time, the harth was nearly in 
the Plain of this Satcilic’s Orbit, lo that it appeared to 
pals very near the Center of Saturn : From hence and 
from fome other preceeding Obfervations. Mr CaJJini 
Concludes that the Nodes of this batellit s Orb are in 
4 degrees of ’f? and X, and that its Inclination to the 
Ecliptick is not much more than half that of the other 
Satellites. Fience it fliould follow that the Elliples ic 
defcribes by its apparent motion about Saturn, when in ' 
It and t are much flatter and nearer to his body, than 
thofe of the other four, which he allows to move* in 
the plain of the and to have their Node^ in it*” | 
of and X, with an Inclination to the Ecliptick of 
31 degrees To confirm this dificovery, he produces a- 
nother Obfervation of his Fathers, near Thirty Years 
before, viz. that. Anno i68y, Maii St. fT. about 
Noon, the fame Satellite was obferved in fuperiour con- 
junction with Saturn, with lefs than one Diameter of the 
Ring North Latitude, Saturn being then^in np 11° 48'. 
So that the Satellite wanted but 7°. ii' of compleating 
134 Revolutions, in the Interval of time between them. i, 
From thefe Data it was eafy to fettle the Theory • 
of this Satellite. i 
As to the Fourth or the Hugenian Satellite; in the • 
Memoirs for but juft now come to hand, we find 
a very curious Obfervation of it, and the firft of its kindi 
viz- i\\2iZ Mart. z$°.S. N. about F. M, this fourth Sa- 
tellite, then in Afogeo, did immerge behind the Body of 
Saturn
