--In February, Campbell's instrument for the registration of
sunshine was introduced: it was mounted in July."
Of private history: "I was at Playford until Jan. 19th, in close
correspondence as usual with Mr Christie at the Observatory, and
attending to my Numerical Lunar Theory.--From Mar. 29th to Apr. 2nd I
went on a short trip to Hereford, Worcester, &c.--From June 8th to
20th I was at Playford.--From Aug. 13th to Sept. 8th Airy was on an
expedition in Ireland, chiefly in the North and West, with his
daughters. When at Dublin he visited Grubb's instrument factory. On
the return journey he stayed for some time in the Lake District of
Cumberland, and took soundings in the neighbourhood of the place of
the 'floating island' in Derwentwater."
Airy took the greatest interest in antiquarian matters, whether
military or ecclesiastical, and his feelings on such matters is well
illustrated by the following letter:
ROYAL OBSERVATORY, GREENWICH, S.E.
_1877, February 27_.
DEAR SIR,
I venture to ask if you can assist me in the following matter.
In the Parish Church of Playford, near Ipswich, Suffolk, was a
splendid brass tombstone to Sir Thomas Felbrigg.
