Downing Street, August 1, 1823.

Dear Aunt,—

I have been long threatening to send you a long letter, but have always been prevented by circumstances and want of leisure from executing my intention. The truth is, I have been so much occupied with astronomy of late, that I have had little time for anything else—the reduction of these double stars, and the necessity it has put me under of looking over the journals, reviews, &c., for information on what has already been done, and in many cases of re-casting up my father’s measures, swallows up a great deal of time and labour. But I have the satisfaction of being able to state that our results in most instances confirm and establish my father’s views in a remarkable manner. These inquiries have taken me off the republication of his printed papers for the present.

I think I shall be adding more to his fame by pursuing and verifying his observations than by reprinting them. But I have by no means abandoned the idea. Meanwhile I am not sorry to hear they are about to be translated into German. There is a Mr. Pfaff, a respectable mathematician, and I hope it is he who undertakes the work. If you can learn more particulars, pray send them to me. I hope this season to commence a series of observations with the twenty-foot reflector, which is now in fine order. The forty-foot is no longer capable of being used, but I shall suffer it to stand as a monument.

I am much obliged to you for the book on temperaments you were so kind as to send me, which seems interesting, but I have not had time to read it through....

P.S.—Your books on animal magnetism, and that for Babbage, arrived safe.... I wish you would procure and send me Pfaff’s translation of my father’s papers as soon as published. Write as often as you can. Your letters are very interesting. I wish I were a better correspondent, but my time is so occupied, I know not where to turn.

P.P.S.—Babbage has had £1,500 granted him by Government to enable him to execute his engine, which is very curious. A report is strongly current of Captain Parry’s successful arrival at Valparaiso; it comes in a very probable form.

1823. Astronomical.
