every clear evening, see the disc advancing, at its 

 setting, to the westward of the object ; and, from the 

 longest day, observe the sun retiring backwards 

 every evening at its setting, towards the object west- 

 ward, till, in a few nights, it would set quite behind 

 it, and so by degrees to the west of it : lor when the 

 sun comes near the summer solstice, the whole disc 

 of it would at first set behind the object; after a time 

 the northern limb would first appear, and so every 

 night gradually more, till at length the whole diame- 

 ter would set northward of it for about three nights ; 

 but on the middle night of the three, sensibly more 

 remote than the former or following. When reced- 

 ing from the summer tropic, it would continue more 

 and more to be hidden every night,, till at length 

 it would descend behind the object again ; and so 

 nightly more and more to the westward. 

 Selborne.
