112 CHRONOMETERS. 



Those who have perused the above statement from Messrs. Parkinson and Frodsham, 

 and are at all interested in the improvement of navigation, cannot but be desirous 

 that a fair trial should be given to this important discovery ; and if it is found that 

 chronometers which are the production of respectable artisans, and which from causes 

 hitherto unknown deviate from their rates, so as to be comparatively useless, can be cor- 

 rected by the application of their principle, so as to become sufficiently perfect for the 

 purposes of navigation, by maintaining the uniform rate within the limits prescribed by 

 Government, no one will deny, that this important discovery should be made public, 

 and that such discovery is fully entitled to a liberal compensation ; and I cannot con- 

 clude this article without recommending it to the serious attention of those whose duty 

 it is to inquire into and reward merit. 



Mr. Murray, a very respectable chronometer-maker of London, being desirous to 

 establish the excellent going of his chronometers, sent No. 620 eight day, 634 two 

 day, and 558 one day, all box chronometers, which could not be a great acquisition 

 to us; and it is but justice to say that they were excellent instruments, for although 

 they all gained at first, they obtained a constant rate, from which they did not deviate 

 whilst in my possession. I regret much that it was not in my power to bring them 

 home, as I have no doubt they would have been found perfect, with the exception of 

 one which met with an accident. 



In addition to No. 571, box chronometer, and of 1081 for the pocket, of Parkinson 

 and Frodsham I purchased No. 418, pocket chronometer, of Barraud, which I knew 

 to be good, having it formerly in my possession ; but the main spring gave way soon 

 after we sailed, which reduced my number to five. These were under the charge of 

 Commander Ross, until July, 1831, after which they were all under my own care, and 

 the only two that were brought home were those by Parkinson and Frodsham.
