Mr. John Mair, at Air, lat. 55° 30' n. says, the eclipse began at 8*' 45™, but 

 that, by reason of clouds, he could make no other particular observation ; only 

 that, by a view he had of the sun some little time before the end, he thinks the 

 end of the eclipse might be about 1 1*^ 48"'.

He says, the best observations make the annulus a small matter narrower on 

 the upper than lower side; by which it appears the centre of the eclipse was to 

 the northward of Dundee. 



Mr. John Stewart, professor of mathematics at Aberdeen, writes, that by an 

 observation made at Montross, lat. 56° 4l'. 



The annular appearance began at 10'' 20*" 0' 



Annulus ended at 10 24 30 



End of the eclipse at 11 52 45 



And that, by an observation made at a place about 18 miles s. w. of Aberdeen, 



The eclipse began at 8^

End at 11 



And that at Aberdeen, lat. 57° ll' n. 



The eclipse began at 8^ 55™ 33^ 



Middle of the eclipse, and annular appearance, 



as near as he could judge, at 10 23 3 



End of the anrmlar appearance at 10 24 48 



He writes also, that he received an account from Mr. Reid, minister at New 

 Macchar, about 7 miles n. w. of Aberdeen, who observed 



The beginning of the annular appearance at. . lO'' 18"" 28' 



And the end of the eclipse at 11 49 3 



Mr. Stewart says, tliat, by comparing his observation at Aberdeen with this 

 of Mr. Reid's, he apprehends he is in a mistake as to his judging of the middle 

 of the eclipse, and annular appearance; and reckons, that the annular appear- 

 ance began at Aberdeen at lO*" IQ"', and ended as above. By which the total 

 duration of the annulus was 5™ 48'; and the end of the eclipse at Aberdeen was 

 at U** 49™ 33'. 



The Rev. Mr. Irwin, at Elgin, lat. 57° 34', says, the eastern limb of the 

 moon touched or entered on the western limb of the sun at S** 57"'; though he
