The great mistake of her life was going back to Germany after Sir W. Herschel’s death in 1822. She was then seventy-two years of age, and the previous fifty years of her life, containing all her most precious memories and associations, had been spent in England. In this country, also, were all those who were dearest to her. Yet, no sooner was her brother dead, than she felt life in England to be an impossibility. She little thought that she had still twenty-six years to live; indeed she had long been under the impression that her end was near, but while her brother lived she kept this to herself, because she wished to be useful to him as long as she possibly could. She never really re-acclimatised herself to Germany. “Why did I leave happy England?” she often said. The one German institution she thoroughly enjoyed was the winter series of concerts and operas, which she constantly attended, and she mentions with pleasure, in her letters, that she was “always sure to be noticed by the Duke of Cambridge as his countrywoman, and that is what I want; I will be no Hanoverian.” She laments the death of William IV., chiefly because, by causing a separation of the crowns of England and Hanover, it seemed to break a link between herself and the country of her adoption. She never revisited England, but she kept up a constant communication with it by letters to her sister-in-law, her nephew, and later to her niece, Sir John Herschel’s wife. At that time the post between London and Hanover was an affair of fifteen days, and letters were carried by a monthly messenger, of whose services she seldom failed to avail herself. She took the keenest interest in her nephew’s distinguished career. His letters to her are full of astronomy. In 1832 he made a voyage to the Cape to observe the stars in the Southern Hemisphere. When Miss Herschel first heard of the intended voyage she refused to believe it. But when she was really convinced of it, the old impulse was as strong upon her as upon a war-horse who hears the trumpet. “Ja! if I was thirty or forty years younger and could go too!” she exclaimed. On 1st January 1840 the tube of the celebrated forty-foot telescope was closed with a sort of family celebration. A requiem, composed by Sir John Herschel for the occasion, was chanted, and he and Lady Herschel, with their seven children and some old servants, walked in procession round it, singing as they went. On hearing of this from Slough, Miss Herschel recalls that the famous telescope had also been inaugurated with music. “God save the King” had then been sung in it, the whole company from the dinner-table mounting into the tube, and taking any musical instruments they could get hold of, to form a band and orchestra.
