This is the south following of the two double stars e and 
5 Lyrae. The change surmised by Sir William Herschel 
in 1804 seems to be well borne out by subsequent obser- 
vations, the total alteration in the angle being no less than 
i3°5i, averaging 0.325 per annum in the direction np sf, or 
retrograde.
