EXPERIMENTS AT SPITZBERGEN.

of the weather, no means occurred of effecting 

 the object in view, but by comparing the clock 

 with nine chronometers, some of which went 

 very indifferently. These comparisons were, for- 

 tunately, rendered unnecessary, as observations 

 were afterwards obtained at Dane's Island in 

 latitude 79° 40' 20" N., and longitude 11° 6' 

 E. ; at which place the clock was landed, and 

 fixed upon a solid mass of granite rock, at the 

 height of forty-five feet above the level of the 

 sea, and the sun's passage over the meridian 

 observed for several days. A detail, therefore, 

 of the comparisons will be needless, with the 

 exception of merely stating, that the mean results 

 at each place indicated a very near agreement.
