VOL. XL.] PHILOSOPHICAL TRANSACTIONS. 175 



The progress of the shadow was towards the south-east ; and "Sethus Calvisius 

 cites the Turkish annals for its being total in some part of their dominions. 



You will perceive by this account, that we have no observatory in this place; 

 but we are in hopes that some time or other we shall obtain one from the patrons 

 of the university. I doubt this last eclipse will not be distinguished by any par- 

 ticular appellation among the populace, as the former that were central in this 

 country. The remembrance of it however will be preserved by the curious, 

 who observed it with great pleasure, and agree that it was the most entertain- 

 ing spectacle of this kind they ever saw. 



4. The same observed at Edinburgh. By Sir John Clerk, Bart. F.R.S. p. IQ5. 



The eclipse began at 5"" 36^ after 2. The annular appearance began at 25™ 

 55' after 3 ; its continuation was 5™ 48^ The end of the eclipse was at 44"* 50* 

 after 4 ; all reckoned by apparent time. We had half a score good reflecting 

 telescopes to make these observations, and our calculations perfectly agreed, so 

 that you may depend upon them as most exact. 



This was not done by us as a matter of mere curiosity, but to assist in 

 ascertaining the motions of the moon, on Sir Isaac Newton's theory, on which 

 a good deal of the doctrine of the longitude will depend. Sir Isaac's calculation, 

 as to the beginning of this eclipse, was pretty right ; but not so well as to its 

 central appearance Two spots in the sun made a very distinct appearance to 

 us, as they entered under the moon's body ; one was a little above the central or 

 horizontal line of the sun ; the other was near the edge, on the east quarter. 

 The first, by comparison with the sun's diameter, was larger than the disk of 

 our earth ; it was dark in the middle, and certainly emitted no fire or light. 

 The edge of the moon appeared a little ragged or rough, but not mountainous, 

 because of the sun's light. There was no considerable darkness, but the ground 

 was covered with a kind of a dark greenish colour. Two stars appeared, the 

 planet Venus, and another farther eastward. This account is what you may 

 depend on.
