Therefore the Mean Annual Precession of a Cephei during the 
period sought for, which we shall see was the last 2,788 years, 
was 24°°573. 
It also appears that the Annual Variation in Declination may 
be taken at 12”°57, which in 2,788 years amounts to 35045”— 
9° 44’ 5”. Deducting this from the present Declination of « 
Cephei, i ¢., 62° 8’ 57", it appears that anno B.c. 890 a Cephei 
had N. Declination 52° 24’ 52”. Wherefore, its distance from the 
N. Pole was 37° 35’ 8’. | And adding to this the distance of the 
pole of the heavens from the Zenith at Stonehenge, i.¢., 38° 49’, we 
obtain that the Zenith distance there of a Cephei was 76° 24’ 8”, 
and its altitude above the horizon was 13° 35’ 52”. 
It remains for us to ascertain the year when the star a Cephei 
‘to which this N. stone has directed us was observed at 
Stonehenge. 
The difference already mentioned between the ar’s of this 
star in this year A.D. 1897, and in the year we are seeking 
for (namely, 19° 1’ 48") amounts to 68,508", and if this quantity 
is divided by 24'-573, as suggested, the result will be seen to be 
2,788 years, exactly the same number that the other mound 
and the North stone gave us. 
SOUTH STONE AND a ANDROMEDZ. 
Lastly we come to the South stone. There are two stations 
within the Temple from which this can be observed. From the
