z. I have at last dilcover’d towards the Middle of the Body of Vetius a t-L"rpart clearer than the rest, by which one may Judge of the Motion, or the VenusT^" M.Rest, of this Planet. CaJIini. ». 32.

Thefxrst time l (inv it, was OBob. 14. 1666. 45'. p.m. and then this^s'*.’ 35 '

Bright part was very near the Center, on the North-side. And at the simetime I observ’d Welhvard two ob, cure Spots, somewhat oblong; but I couldnot then see that Resplendent part long enough to conclude any thing fromthencc, nor was 1 able to see any thing well ot thole parts till April 28. 1667.on which Day a quarrer of an Hour before Sun-rising, I siw again a Brightpart, scituated near the Secti m, and distant from the Southern Horn a lirtlemore than i of its Diameter. And near the Lastern Ring I siw a Dark andsomewhat Oblong Spot, which was nearer to the Northern than the SouthernHorn. At the Rising of the Sun I perceived, that this Bright part was thenno more sb near the Southern Horn, but distant from it V of its Diameter.

This gave me great Satisfaction. But I was furprised at the sime time tofind, that the sime Motion, which was made from South to North in theInferiour part of the Disk was on the Contrary made Irom North to South inthe Superiour part; whence the Determination of the Motion may be bestertaken : For we have no Examplc of the like Motion, except it be in that ofthe Libration of the Moon.

The next Day, at the Rihng of the Sun, the siid Bright part was not farfrom the Section, and distant from the Southern Horn ‘ of the Diameter.

When the Sun was 4 Degrees high, the sime was scituated near the Section,remote from the Southern Horn } of the Diameter. The Sun being high6° io 7 , it seemed to have passed the Center, and that the Section of theDisk did cut the sime. The Sun being 7 0 high, it appeareJ yet moreadvan-ced Northward, together wiih two Obscure Spots feated between the Secti-jon and the Circumference, and equally distant from one another, and from'each Horn on both Sides. And theSky being very ciear, 1 observed the Mo-tion of the Bright part for 1 which then leemed to be exactly made fromSouth to North without any sensible Inciination Fast ward or Westward.
