MISS HERSCHEL TO DIETRICH HERSCHEL.

Slough, August 4, 1786.

Dear Brother,—

We received yesterday William’s and Alexander’s letter, and find that they intend to leave Hanover on the 8th of August, therefore they will not see the contents of this. However, as you have an instrument, I think you are entitled to information of a telescopic comet which I happened to discover on the 1st of August, and which I found, by the observations of the 2nd, to have moved nearly three-quarters of a degree. Last night it was cloudy, but I hope the weather will be more favourable another night, that we may see a little more of it. I believe you have a pair of Harris’s maps; the place where I saw the comet is between 53 and 54 Ursæ Maj. and the 14, 15, and 16 Comæ Ber. of Flamsteed’s Catalogue. All stars of Flamst. are in Bode’s Cat. to be found, and if you cannot do without it, I dare say it is to be met with at Hanover....

I found it with a magnifier of about 30, with a field of about 1½ degree. Now, if you have a piece which is nearly like this, I would advise you to make use of that in sweeping all around this place, for it must be, by the time you receive this letter, at a considerable distance.

When I saw it, it appeared like a very bright, but round, small nebula.

The first letter I received from Hanover from William gave us the greatest satisfaction imaginable, for it contained an account of the good health of all our dear relations. I hope our dear mother does not grieve too much now they have left her. I dare say William will pay soon another visit, and then I will take that opportunity of coming to see her. Farewell, dear brother; give my best love, &c.

To this period of Miss Herschel’s life belongs a folio manuscript book, written with the utmost neatness, which she sent with one of her various consignments of papers to her nephew after her return to Hanover, and introduced as follows:—
