oy of Mr. Hugim and I^lr - Mariotte. The firft obfer vations of 
the diftances were made by ao Eftimaie of the Ey€,co£DpariDg 
the exterior Satellit to Saturn and to the other Satellits* The 
laft were made by the meafure of the Time between the paft 
iage of the Planetj andth^atof the Ceotcr of Saturn. 
ThisNew Planet did more and more remove frotn Saturo 
till the 9th of February^ when wc meaftir'd the difference be. 
tween his paflage and that of the Center of Saturn to be 50*' 
of an hour, which give at leaft 10 diameters of Saturn^ but on 
the sothj he was already too near the beams of the Suo, to 
meafure his diftance 5 which yet by eftimat was judged greater 
than it bad been the ipth.The divcrfefcituations af this Placer,

^ By the apparent fwiftnefs of his Motion during the firft days^ 
'tis eafie to (tt^ that this PJaiiet had been fecn in ConjunftioD 
with Saturn Fe^r.j > and by his motion on the Weft ic appears, 
that he was in the inferior part of his Circle : And becaule du. 
ring this time of 17 days he removed more and more fro© 
turn J ^tis certain that he remained in the fame quadrant of the 
inferior Occidental Circle above 17 days^ and that his whole 
Revolution is iwm than 68 days^ 
He was thefelaft days at a diftance almoft equal to that 
which he hadabout the end of 03 ok 1(^7 1 jfo that in 480 days 
or thereabout he made a certain number of Intirc revolutions, 
which can be no more than 75 fiocc each of them is without 
queftipo of more than 68 days. If you fliould count 7 of 
them, each would be 68j days j if you count 6, each would 
k- A ^ youcount but 53 each would be 0 days. But 
this laft fuppofition can by no means be made to agree with the 
two Oblervations of Denmb. 1S72, and the firft doth not 
agree fo well with them as the fecond.
