But the Eleventh of the fame^abouc fix a clock at night, being 
furniflit only with a three-fooc glaP, he remarlied in the Sun's 
difque I wo Spots very darkj diftant from his apparent Center 
about the third part of his Semi- diameter. And that he might 
the more exactly note their fcituation, in refped: of the fe vera! 
parts of the world,he made ufe of two very fine thredsj cutting 
one another at right angles in the common focus of the two 
glalles and in the Axis ofthe Telefcope ; And having dire«2:ed 
It toward the Sun , he fo turned it, that letting it afterwards 
reftjOne might fee the Center of theSun^ according to one of 
thele threds, advance Weftward^ this fame thred marking in 
the Sun a Circle parallel to the Equator:^ and the other thred 
marked the Circle of Declination 3 or the Horary Circle of the 
faidSun* See Tab, 11. Fig, I. 
Then he obferv^d^ that the Spots were in the Southern part 
of the Sun i that their elongation from this parallel^ palling 
through his Centerj could be no more than about ihc Sixtieth 
part of his Diameter; and that they were fciruate on the 
E3ftern fide in refpeit ofthe Liid Center of the Suo. He alfo 
meafur'd feveral times^ from fix a clock at night to feven^ the 
timCj which iapfed between the palTage of the Sun's cenrer.and 
that of thefirft of thefe Spots throiigh ihe faid horary Ctrcle ^which 
fometimes he found to be twenty three, fometimes twenty two 
feconds, the feaii-diaaieter of the Sun then pafiing in fixty fix 
feconds. 
The firft of thefe Spots^beiog iook'd upon with a Telefcope 
ot leventeenfoot long, appeared of a iomewhat Oval figure • 
the other was oblong and a little curv'd, like the Hebrew letter 
Jod'^ and both together v^ere furrounded by a mV/<^ orcoro- 
necmade.op of Hale dark poinrsj which conformed it felf to 
the figure of the Spots, confidered ss they were joyned to- 
gether : which coronet was more exacStiy obferved the days 
foliowing. 
T\\t twelfth Augujlht obferv'd them from the ttmeofSun- 
rlfingj and perceived that no they were nearer his Center,.' 
The time between the paffage of the Suns center,and that of the 
interior edge of the Coronet which encompafs'd them both, 
was then of fixteen feconds. At (even a clock it was but of 
fifteen, and the Southern limb of the Coronet couched the 
paraliel paffiog through the Sun's center.
