plants, and thence proceeding to the vernal and aestival, and concluding with 

 the autumnal. 



Ohservations, made hy Mr. Hooke, of some Spots in the Sun, which 

 returned after they had passed over the upper Hemisphere of the Sun 

 which is hid from us; according as tvas predicted. See iY" J 5, p. 631 

 of this Abridgement. N" 77, p- 2595. 



August 30, 1671, about noon, I saw a large spot in the centre of the sun's 

 face, but had not then time to make any more exact observation of it. 



Sept. 1 , at three o'clock, I saw the same spot moved about a quarter of the 

 diameter of the sun westward, and it appeared to consist of one greater and 

 two lesser black spots with a dusky cloud encompassing them : the diameter of 

 the whole phenomenon was about -^ of the diameter of the sun, and it was 

 distant from the next adjoining limb J-|, that is exactly one quarter of the 

 diameter of the sun. This I examined and measured several times, and found 

 very exact. 



Observations, made by the same, of the late Eclipse of the Moon, the 

 8th of September, IGJI, Old St. N' 77, p- 2296. 



September 8, 167 1, at 7 h. 27-l-m. I first observed the moon eclipsed, when 

 it began to be enlightened, the total darkness being already past. The shadow 

 passed through the middle of the spot called by Hevelius M. Porphyrins, half 

 of the said spot appearing without the shadow and the other half being darken- 

 ed thereby. — At 7 h. 49m. the shadow passed through the middle of M. Sinai, 

 through the middle of the eastermost of the three lakes called Mare Adriaticum, 

 and just touched the ridge of the Appennine mountains. — At7h. 54 m. it 

 passed the middle of the J. Besbicus in the Propontis. — At 8 h. 04- m. it passed 

 through the straits of the Pontus Euxinus at the promontories Acherusia and 

 Aristes. — At 8h. 64-m. it touched the Palus Maeotis, which Palus Maeotis was 

 then distant from the limb of the moon next adjacent one third part of its 

 shorter diameter or breadth. — At 8h. J 7 m. the shadow went off the body of 

 the moon upon the innermost limb line of Hevelius's large chart of the moon 

 at the 29th division, just without the J. Major of the Caspian Sea. The duskish 

 penumbra left not the limb of the moon quite without some kind of darkness, 

 till 8h. 29 m. at which time I found that side of the moon which the shadow 

 last left, was full as light and clear as the other. 



About four or five minutes after the shadow was gone off, I perceived a 

 faint representation of colours upon that part of the body of the moon which
