1872
"From the Report to the Board of Visitors it appears that 'The Normal
Siderial Clock for giving sidereal time by galvanic communication to
the Astronomical Observatory was established in the Magnetic Basement
in 1871, June; that locality being adapted for it on account of the
uniformity of temperature, the daily changed of temperature rarely
exceeding 1 deg. Fahrenheit. Its escapement is one which I suggested many
years ago in the Cambridge Transactions; a detached escapement, very
closely analogous to the ordinary chronometer escapement, the pendulum
receiving an impulse only at alternate vibrations.... The steadiness
of rate is very far superior to any that we have previously
attained.'--The aspect of railway enterprise is at present favourable
to the Park and to the Observatory. The South-Eastern Railway Company
has made an arrangement with the Metropolitan Board of Works for
shifting the course of the great Southern Outfall Sewer. This enables
the Company to trace a new line for the railway, passing on the north
side of London Street, at such a distance from the Observatory as to
remove all cause of alarm. I understand that the Bill, which was
unopposed, has passed the Committee of the House of Commons.
