Matthew Stewart , the prefent Profefl.br, having no 
proper Inftruments, had not as yet re-eftablifhed it ; 
which we hoped to do by an Inftrument, which we 
every Day expe&ed from London ; and Mr. Stewart 
having promifed to make the beft Obfervation he 
could, we refolved to fet out for Aberdour , a Seat 
of the Earl of Alortons, which he readily offered to 
us, and did us the Honour to accompany us thither 
himfelf, having the fame Deflre and Curiofity to do 
whatever lay in his Power to contribute to an exaft 
Obfervation. 
Aberdour is about 10 Miles almoft N. W. of Edin- 
burgh . W e chofe this Place, as being, by the Com- 
putations of this Eclipfe, at or very near the Southern 
Limit of the Annulus . 
In the Caftle of Aberdour , Lat. y6° 4! N. and 
2y // of Time Weft of the College of Edinburgh 
we fet up a Clock, July 9. and the Weather being 
cloudy, and our Equal Altitude Inftrument and 
Tranjit not being yet arrived, we on the 11 th made 
ufe of an Equatorial Telefcope of my Lord Morton s, 
to find correfponding Altitudes of the Sun, and at 
the fame time put up a Gnomon of 1 y Feet high. 
Being uneafy that our Inftruments were not come 
to Hand, and refolving to have a Communication 
with the College of Edinburgh , where they had a 
Tranjit Inftrument 5 my Lord Morton propofed that 
two Cannon fhould be fired from the Caftle of Edin- 
burgh , one precifely at 12 o’ Clock, and the other 
at y' after 12 on the Day of the Eclipfe ; and the 
different Obfervers in different Parts of the Country 
to be advertifed of this, and to mark down the 
precifc Time of feeing the Flafh, or hearing the 
Sound
