It is not yet finally
adjusted.--Some magnetic observations in the Britannia and Conway
tubular bridges were made last autumn. For this purpose I detached an
Assistant (Mr Carpenter), who was aided by Capt. Tupman, R.M.A.; in
other respects the enterprise was private and at private expense.--The
rates of the first six chronometers (in the annual trials) are
published, in a form which appears most likely to lead to examination
of the causes that influence their merits or demerits. This report is
extensively distributed to British and Foreign horologists and
instrument-makers. All these artists appear to entertain the
conviction that the careful comparisons made at this Observatory, and
the orderly form of their publication, have contributed powerfully to
the improvement of chronometers.--Very lately, application has been
made to me, through the Board of Trade, for plans and other
information regarding time-signal-balls, to assist in guiding the
authorities of the German Empire in the establishment of time signals
at various ports of that State. In other foreign countries the system
is extending, and is referred to Greenwich as its origin.--The
arrangements and preparations for the observation of the Transit of
Venus occupied much attention.
