fervers of the Sun, as were then perpetually peeping 
upon him with their Telefcopes in England, France , 
Germany, Italy, and all the World over, whatever might 
be before, from Scheiner s time. The reafon, I fay, of 
this long difippearance of the Spots, I take to be from 
the want of extraordinary Eruptions in that fiery Globe. 
The Sulphureous, or other Matter, or Pabulum of thofc 
Eruptions, is fpent or diflipated, and that Globe conti- 
nues in its natural ordinary burning State, till there 
happens to be a frefti Collection of Sraoaking, Difplo- 
five, and extraordinary Matter, that caufeth a new E* 
ruptiqn. Which Eruptions generally happen between 
what we may call the Suns Tropicks, or in his Torrid, 
Zone : For I never obferv’d any Spots to be near the 
Suns Poles. And if I mifremember not, the Spots in 
'Scheiner' s Cuts are all about the .middle Zone of the 
Dixk. The greatest Evagation 1 ever obferved of them 
was March 8 . 1704. On which Day, befides the dark 
Spots in the ufual Zone, I perceived fome faint Spots, 
fcarce vifible, much nearer the Southern Pole than I e- 
ver had feen them. But this was, no doubt, in fome 
meaftire owing to the Pofition of the Earth in refpeft 
of the Sun, as well as to the Southerly Place of the 
Spots on him : For, about the Equinoxes, the Spots 
feem to march pretty far towards the Poles of the Sun, 
as may be feen by the annexed Schemes. (Tab. II.) 
Having thus obferv’d what part of the Sun the Spots 
commonly poffefs, I fhali next take notice of their Stages 
and Path over the Sun. That the Sun moveth round 
his own Axis, is manifefl, beyond doubt, from the Mo- 
tion of the Spots. And that the Spots feem to trarerfe 
the Sun, fometimes in Strait Lines, fometimes-in Curve 
Lines, curved this way, and that way, is as manifeft 
alfo, and well known to the Curious, and is fet forth 
in the annexed two Figures :* Which Figures fhew the 
Stages of the Spots every Day that I obferv’d them,
