I have sent by Mr. G. a few copies of a work of mine on Light, for you to distribute. I shall by the next opportunity (_possibly by this_) send some copies of a third catalogue of double stars, completing the first 1,000. The nebulæ are advancing rapidly; I have got about 1,500 re-observed. Your affectionate nephew, J. F. W. HERSCHEL. MISS HERSCHEL TO J. F. W. HERSCHEL. _June 3, 1828._ MY DEAREST NEPHEW,— * * * * * And I must once more repeat my thanks to you (and perhaps to Mr. South) for thinking so well of me as to exert yourselves for having the great and undeserved and unexpected honour of a medal bestowed on me.... Here I was interrupted, and all along of the medal; for my friends are all coming to congratulate me, and leave me no time to think of what to say of myself; but I will soon write again, and for the present will only beg that you (or Miss Baldwin, for I dare say she knows,) will give me the history of the medal, such as whose head it is which is on the one side? (I know who it is like very well) and if the impression is to be permanent? Next, I wish to know if you, or the Royal Society, or the Observatory at Greenwich (the latter I think must be) are in communication with the Imperial astronomer Littrow? If you have seen any of the publications which are yearly printed at the expense of the Emperor, I could wish, if it is not too much trouble to you, to know what you think of the work; because Count Rupfstein, Chargé d’Affaires, sent me the copy (which was to go to Göttingen) to look at, and since then he wants my opinion about it. And I know no more about it than that it is a book printed on fine paper, large folio, of 195 pages, with seven plates of the New Observatory made out of the old one, built at the top of the seventh story of the University at Vienna, a description of the store of instruments, thirty-five articles including rules, two spirit-levels and a case of drawing instruments; tables of precession, aberration, and nutation of ninety-four of the principal stars for the beginning of the year 1835; but I forgot the rest; but so much I remember, that the whole book is filled with these ninety-four stars, of which I cannot comprehend the use, but I say nothing about it, and _hum_ and _ha_ when the good man begins to talk about it. Dear nephew, adieu! I am, your affectionate aunt, CAR. HERSCHEL. [Sidenote: 1828. _Thanks for Bracelets._]
