484. Timekeeper, which was twice carried out by Captain 

 Cook. The Royal United Service Institution. 



This timekeeper is thus spoken of in Cook's Voyage to the Pacific, 1776, 

 Vol. I., p. 4 : "I had likewise in my possession the same watch or time- 

 " keeper which I had in iny last voyage, and which had performed its part 

 " so well. It was a copy of Mr. Harrison's, constructed by Mr. Kendall." 



This watch was taken out again by Captain Bligh, 1787, and when the 

 crew of the " Bounty " mutinied it was carried by the mutineers to Pitcairn's 

 Island. In 1808 it was sold by Adams to an American, Mr. Mayo Fletcher, 

 who sold it in Chili, and in 1840 it was purchased for fifty guineas by Sir 

 Thomas Herbert. It was repaired and rated at Valparaiso, and taken by Sir 

 Thomas to China, and brought home in the " Blenheim" in 1843, having kept 

 a fair rate with the other chronometers for the space of three years.

H. M. Commissioners of Patents. 



This clock is of Swiss manufacture, and supposed to have been made in the 

 year 1348. It was obtained from Dover Castle, and had never been removed 

 from there till the year 1872. It is interesting from the fact of its having the 

 verge escapement, which was used many years before the pendulum. 



444. Clock Dial. The hours, six only, are indicated by 

 perforated Roman letters. The hand or pointer is formed of a 

 revolving disc, painted in oil, with the subject of Aurora and 

 the Hours ; it must have gone round four times in 24 hours. 

 The dial is fitted in the original carved door of the clock.
