Airy, George Biddell, 1801-1892

"Autobiography of Sir George Biddell Airy"

--I had
always something on hand about Tides. A special subject now was, the
cry about intercepting the tidal waters of the Tyne by the formation
of the Jarrow Docks, in Jarrow Slake; which fear I considered to be
ridiculous."
Of private history: "From Jan. 15th to 24th I was at Playford.--On
Mar. 4th I went to Dover to try time-signals.--From June 24th to
Aug. 6th I was at Little Braithwaite near Keswick, where I had hired a
house, and made expeditions with members of my family in all
directions. On July 28th I went, with my son Wilfrid, by Workington
and Maryport to Rose Castle, the residence of Bishop Percy (the Bishop
of Carlisle), and on to Carlisle and Newcastle, looking at various
works, mines, &c.--On Dec. 24th I went to Playford."

1854
The chronograph Barrel-Apparatus for the American method of transits
had been practically brought into use: "I have only to add that this
apparatus is now generally efficient. It is troublesome in use;
consuming much time in the galvanic preparations, the preparation of
the paper, and the translation of the puncture-indications into
figures. But among the observers who use it there is but one opinion
on its astronomical merits--that, in freedom from personal equation
and in general accuracy, it is very far superior to the observations
by eye and ear.
