Mr. Halley soith, That he sow the Spot again on the sifth day, at 8 h . 30'.Ma>;e, very near the Limb of the Sun, so that it appeared only as a rineLine ■ but by reason of its finencts and the too great Height of the Sun, hecould not take any mealüres to determine its Place and Labnide by j and thatAvhile the Spot continued one, as it was July 2.5. he mcafüred to the middle ofit; as also when the pieces were divided, but not far disjoined : Afterwards,when they were separated considerably, he oblerved the middle of the oiggerSpot, which was to the South, apparently, I fuppose ; but really, North :sor so only bis Observations will agree with those of Mr. Flamstced exactly.

Hence it feems very Evident, (säith Mr. Flamsiccd) that the Spots way wasnot Inclincd to the Ecliptici t fix or feven Degrees, as Scheinet and some othersmake it, but much lcß, by the joynt Content of the Obiervations of both•our Oblervers. Mr. 1 -Iallcy adds, That coniidering the Motion of the Spotcroß the Sutis Difque, as both their Oblervations givc it, it appears that theLatitude was not so great at itsEntrance into the Sun as in the middle ,of him.'And by Mr. Flamßced's Obsorvation it was greatest on the first of AugujLand thcn again Inclining towards the Ecliptick. If you grant this, it wsllfollow, (inters Mr. Flamstced) that the Sutis Axis was Inclined to the Plain ofthe Orbis Magnus ; but the quanti ty of this Inclination must not be very

great.
