"In the South-East Dome, the alteration proposed last year for
rendering the building fire-proof had been completely carried out. The
middle room, which was to be appropriated to Chronometers, was being
fitted up accordingly.--From the Report it appears that 'our
subterranean telegraph wires were all broken by one blow, from an
accident in the Metropolitan Drainage Works on Groom's Hill, but were
speedily repaired.'--In my office as Chairman of successive
Commissions on Standards, I had collected a number of Standards, some
of great historical value (as Ramsden's and Roy's Standards of Length,
Kater's Scale-beam for weighing great weights, and others), &c. These
have been transferred to the newly-created Standards Department of the
Board of Trade."--In the Report is given a detailed account of the
system of preserving and arranging the manuscripts and correspondence
of the Observatory, which was always regarded by Airy as a matter of
the first importance.--From a careful discussion of the results of
observation Mr Stone had concluded that the refractions ought to be
diminished.
