Is in Berlin together with the astronomers J. F. Encke and F. W. Bessel. Relates their researches. The new Berlin Observatory is a magnificent affair. May have to travel home sooner than expected owing to the illness of his mother-in-law.
Hears that JH expressed to William Whewell great pleasure in parts of CL's book. Has been altered and improved since the 1st edition. When in Copenhagen last year [H. C.] Oersted was reading JH's paper on double stars. Murray has sold 1750 copies of CL's book.
Has interpolated the hourly tidal observations for Simon's Bay.
Will be obliged for the Tide Observations book of Table Bay. Intends to enter into an agreement with the Tide Master.
Sends the Tide observations made in Table Bay. These are now at a standstill due to the expense involved. Tomorrow he intends to engage the Tide Master. Do they wind up with a dinner?
Only made two copies of the Tide Observations, one for the Observatory and one to be forwarded to the Admiralty. Is engaged instrumentally with the transit instrument. Has engaged a new carpenter for the observatory.
Sends TM some tide observations, and some calculations done on them.
Glad the government has recognized Mrs. Somerville's work. Discusses the hostility toward natives at the Cape and criticizes actions of colonists. Astronomical observing conditions at Cape are very good.
Visits F. W. Bessel in Berlin to discuss pendulum experiments. [C. A.] Steinheil invented a photometer to measure relative light of different stars.
On JH's portrait, which RS is trying to send to JH at the Cape. Asks JH to forgive the 'liberty' he has taken with JH's 'physiognomy,' but RS wants to show off JH as an 'ornament' of Cambridge. Updates JH on Francis Baily's progress and the status of the St. Helena Observatory.
Busy interpolating the Simon's Bay tidal series; JH then intends to study Table Bay and to compare the results. Asked William Whewell to back an application to the British Admiralty for a tide clock to be erected at Simon's Bay as a permanent tide station.
