of Feagh Main near Valencia in Ireland.  The longitude of Feagh Main, found by different methods is as follows:  By chronometers in 1844, 41m 23.23s; by galvanic communication with Knight’s Town in 1862, 41m 23.37s; by galvanic communication with Foilhommerum in 1866, 41m 23.19s.  The collected results for longitude of Cambridge U.S. from different sources are:  By moon-culminators (Walker in 1851, and Newcomb in 1862-3), 4h 44m 28.42s and 4h 44m 29.56s respectively; by Eclipses (Walker in 1851), 4h 44m 29.64s; by occultations of Pleiades (Peirce 1838-1842, and 1856-1861), 4h 44m 29.91s and 4h 44m 30.90s respectively; by chronometers (W.  C. Bond in 1851, and G. P. Bond in 1855), 4h 44m 30.66s and 4h 44m 31.89s respectively; by Atlantic Cable 1866, 4h 44m 30.99s.—­After noticing that many meteorological observatories had suddenly sprung up and had commenced printing their observations in detail, the Report continues thus:  ’Whether the effect of this movement will be that millions of useless observations will be added to the millions that already exist, or whether something may be expected to result which will lead to a meteorological theory, I cannot hazard a conjecture.  This only I believe, that it will be useless, at present, to attempt a process of mechanical theory; and that all that can be done must be, to connect phenomena by laws of induction.  But the induction must be carried out by numerous and troublesome trials in different directions, the greater part of which would probably be failures.’—­There was this year an annular eclipse; I made large preparations at the limits of the annularity; failed entirely from very bad weather.”—­In this year Airy contributed a Paper to the Institution of Civil Engineers ’On the use of the Suspension Bridge with stiffened roadway for Railway and other Bridges of Great Span,’ for which a Telford Medal was awarded to him by the Council of the Institution.  And he communicated several Papers to the Royal Society and the Royal Astronomical Society.

Of private history:  There was the usual visit to Playford in January.—­In April there was a short run to Alnwick and the neighbourhood, in company with Mr and Mrs Routh.—­From June 27th to July 4th he was in Wales with his two eldest sons, visiting Uriconium, &c. on his return.—­From August 8th to Sept. 7th he spent a holiday in Scotland and the Lake District of Cumberland with his daughter Christabel, visiting the Langtons at Barrow House, near Keswick, and Isaac Fletcher at Tarn Bank.

In June of this year (1867) Airy was elected an Honorary Fellow of his old College of Trinity in company with Connop Thirlwall, the Bishop of St David’s.  They were the first Honorary Fellows elected by the College.  The announcement was made in a letter from the Master of Trinity (W.H.  Thompson), and Airy’s reply was as follows: 

ROYAL OBSERVATORY, GREENWICH,
LONDON, S.E.
1867, June 12th.

MY DEAR MASTER,

I am very much gratified by your kind note received this morning, conveying to me the notice that the Master and Sixteen Senior Fellows had elected me, under their new powers, as Honorary Fellow of the College.
