I was furprifed at the fame time to find, that the fame Mo- 
tion 3 which was made from South to North in the inferior 
part of the Diske , was on the contrary made from North to 
South in the fuperior part 5 whence the determination of the 
Motion may be better taken. For we have no example of 
the like motion , except it be in that of the Lihration of the 
Moon. 
The next day , at the rifing of the Sun , the faid bright 
part was not far from the Se5iion^ and diftant from the Southern 
Horn ;of the Diameter. When the Sun was 4, deg. high, 
the fame was fcituated near the Section^ and remote from the 
Southern Horn ] of the Diameter. The Sun being high 5.d. 
lo^ it feem'd to have beenpaffed the Center , and that the 
SecSion of the Disk did cut the fame. The Sun being 7. deg. 
high, it appeared yet more advanced North- ward, together 
with two obfcure Spots, feated between the Section and the 
Circumference^ and equally diftant from one another, and from 
each Horn on both fides. And the Sky being very clear, I 
obferv'd the motion of the bright part for ig houre^ which 
then feem'd to beexadily made from South 10 North, without 
any fenfible Inclination Bafi-ov Wefl-rvard. Mean- time I per- 
ceived in the motion of the dark Spots fo great a Variation, 
that it cannot be adfcribed to any reafon in opticks. 
May 10. and ij. before Sun- rifing, I faw ftill the bright 
part near the Center North-ward. 
Laftly, ^unc 5. and 6, before the rifing of the Sun, I faw 
the fame between the Northern-Horn and the Center of this 
Planet ^ and 1 noted the fame irregular Variation in th^ obfcure 
Spots. But when Fen^ began to be further removed from the 
Earthy it was more difficult toobferve thefe Phcenomena, 
I fliall not prcfume to declare my fentiment touching thefe 
Apparances fo boldly, as / did concerning the Spots former- 
ly difcover'd in Jupiter and Mars. For thofe fpots / could 
very well obferve for a whole night together, during the op* 
pofition of thofe Planets to the Sun : / could confider their 
Motion for the fpace of feverall hours 5 and at laft , feeing 
them return regularly to the fame place, / could judge, whe- 
ther they were the fame fpots^r not , and in how much time
