Bothkamp, Holstein 1890 August 7.
According to your wishes I send you herewith some copies of the negative I took of Jupiter 1889 August 7 after it had been occulted by the Moon.
As you may have seen out of the report A. N. 2928 the photograph has been made but some time after the reappearance, so that Jupiter's image is near the edge of the plate.
The details are naturally still more indistinctly to be seen on the copies than on the negative.
I likewise made some photographs for you from the drawing I took of the reappearence itself, which I take the liberty of offering you as well as some prints of the same manner as they were published by the Astronomische Nachrichten.
I have the honor, to be, Gentlemen
Your most humble
