Note 37 — Chapter VI · LIFE IN HANOVER—continued.

The author of this hasty address feels no slight gratification in having been present on the 1st June, 1821, at the last observations with the twenty-foot reflector, in which Miss Herschel was engaged. He remembers also, not without regret, but with becoming gratitude, that the mirror used for his improvement, on the occasion was inserted, for the last time, in the tube, by the hands of Sir William Herschel.—Memoirs Astronomical Society, Vol. III., p. 409.
