XXVII. Afin, 1684. Apr. if. About an hour before Noon I diseovereda large Spot entred within the Suti’ s Disk a little distant from his following Afr. Flamsteed.Limb. These Appearances how ever frequent in the days of Scheinet and “• 1 5/- ?- 53t> ;Galileo , have been so rare of late, that this is the only one I have seen in hisface since December 1676. By the observed Metidional Distances of it, andthe Suns Southern Limb from the Vertex at Noon, 1 tound it to have zsi 40".more North Declination than the Suns Center, and at 3h. zysi aster Noon,

I measored its Distance from his next Limb 40".

Next Morning, April 26. I fiw it more Remote from his Limb, and bythe Observations then made (at 8 h. manh,) determined its Longitudo fromthe Suns Axis 664 Deg. and its Declination from the Solar Equator qf Deg.

South. Whence lupposing the Revolution, of any point of the Sun to thefime fixed Star to be performed in 27 days 6 hours, the Angle of his Equa-tor and our Eclipticis 7 Deg. and the Longitude of his Northern Pole irp 16 Deg,

I designed the Line of. its Way or Trace over the Sun, and the Points in itwhere the Spot would appear every Morning aiter at the fime hour, till itsEgress on the 8th of May , which Pfound altogether consirmed by such Ob-fervations as I made till then ; 1 b thut I had no reason to doubt of theThcbry..
