On July 14th the Admiralty referred to me a Memorial of Mr J.G. Ulrich, a chronometer maker, claiming a reward for improvements in chronometers.

Finally arrangements were made which put the chronometer business in proper subordination to the scientific charge of the Observatory.

The regular chronometer movement, because of its delicacy, is out of the question for rough land or water travel.

reference to the re-determination of the longitude of Valencia, it is stated that "The concluded longitude agrees almost exactly with that determined by the transmission of chronometers in 1844; and entitles us to believe that the longitudes of Kingstown and Liverpool, steps in the chronometer conveyance, were determined with equal accuracy.

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 reduction of the Ancient Lunar and Planetary Observations, the attention to chronometer constructions, the proposed management of the printing of papers relating to important operations at the Cape of Good Hope; these and similar operations have taken up much of my time.

Having received from the Admiralty the funds necessary for immediate operations, I have commenced with the photographic registers of the thermometers, dry-bulb and wet-bulb, from 1848 to 1868.Our chronometer-room contains at present 219 chronometers, including 37 chronometers which have been placed here by chronometer-makers as competing for the honorary reputation

For a fortnight, once, Captain Dan Cullen was without a meridian or a chronometer sight.
