Life and Works

In 1818 (December 16), Herschel went to London to have his portrait painted by Artaud. While he was in London his will was made.[1]

In 1819 there is a glimmer of the old-time light. In a note Herschel says:

"Lina:—There is a great comet. I want you to assist me. Come to dine and spend the day here. If you can come soon after one o'clock, we shall have time to pre-

The copyhold and other lands and tenements at Upton-cum-Chalvey, in the County of Bucks, and at Slough, he decrees to his son, with £25,000 in the 3 per cent. Reduced Annuities. £2,000 are given to his brother Johann Dietrich, and annuities of £100 each to his brother Johann Alexander and to his sister Carolina; £20 each to his nephews and nieces, and the residue (with the exception of astronomical instruments, telescopes, observations, etc., which he declares to have given, on account of his advanced age, to his son for the purpose of continuing his studies) is left solely to Lady Herschel."—Gentleman's, Magazine, vol. xcii., 1822, p. 650.It is not necessary to say here how nobly Sir John Herschel redeemed the trust confided in him. All the world knows of his Survey of the Southern Heavens, in which he completed the review of the sky which had been begun and completed for the northern heavens by the same instruments in his father's hands. A glance at the Bibliography at the end of this book will show the titles of several papers by Sir John, written with the sole object of rendering his father's labors more complete.
