Canonbury.
These lines are taken from the "Elegy on the Death of Addison," written by
Tickell. They are, if I remember rightly, inscribed on the gravestone
recently placed over his remains by the Earl of Ellesmere, in the north
aisle of Henry VII.'s Chapel. The last two lines which your correspondent
quotes should be as follows:
"Nor _e'er was to the bowers of bliss convey'd_
A _fairer_ spirit, or more welcome shade."
