present with us at Edinburgh during our observation. The whole duration of 

 the eclipse was 5Cf less by his, than by our observation. Nor was the eclipse 

 annular at Morpeth, whence Mr. John Willson writes, that the body of the 

 moon appeared almost entirely on that of the sun; an4 that, to the naked eye, 

 the disk, of the sun seemed to be almost round. 



But of all the observations that have been communicated, that of Mr. Long 

 at Longframlington, 7 computed miles north of Morpeth, determines the 

 southern limit with the greatest exactness. The annulus, he says, was very 

 small there on the upper part, and the duration 40 or 41 half seconds, mea- 

 sured by a pendulum 9.8 1 inches long; from which we may conclude, that the 

 limit was very near this place. This curious observation, with several others, 

 was communicated by Mr. Mark at Dunbar. At Alnwick, in Northumberland, 

 the eclipse was annular, but the time of its continuance was not measured. 



At Berwick, the annular appearance continued between 4 and 5 minutes: 

 the end of the eclipse at Dunbar, by Mr. Mark's observation, was at 4*^ 48™ 

 16^; but some mistake was committed in reckoning the vibrations of the pen- 

 dulum, in measuring the continuance of the annulus. 



At St. Andrew's, this appearance was observed to continue precisely 6™, by 

 a pendulum clock, by Mr. Charles Gregory and Mr. David Young, professors 

 in the university. By a figure of the annulus taken from its image, projected 

 through a telescope on a paper screen, the breadth towards the south-east part 

 of the sun's disk, was rather more than double of its breadth towards the 

 opposite part. 



The observation at Montrose has been already mentioned. At Aberdeen the 

 annulus was observed by Mr. John Stewart, math. prof, for 3"^ 2^ It was 

 almost central, when the clouds deprived him of any further view of it; he 

 thinks it probable, that it continued there about 6". Several gentlemen, resid- 

 ing on the coast northwards from Aberdeen, were desired to observe the coutir 

 nuance of the annulus; but I do not find that any of them saw this pheno- 

 menon from the beginning to its end. 



At Elgin, the eclipse was observed annular at 3^ 29"", the larger part of the 

 ring being uppermost, by the Rev. Mr. Irvin, who had a view of it for about 

 3(y; but by reason of intervening clouds could not determine the beginning or 

 end of this appearance. At Castle Gordon, Mr. Gregory had one view of the 

 eclipse while it was annular, but could make no further observation for the same 

 reason. 



At Inverness, the eclipse was annular for some minutes, as observed by several 

 gentlemen; but they did not measure the precise time how long it continued. 

 By the accounts from Fort Augustus and Fort William, it is doubtful whether
