168 ON THE EFFECTING OF 



Objects, such as ships, leave an impression on the eye, in 

 the medium of this ice bhnk. so that whichever way the 

 spectator turns, he beholds the same objects still represented 



the higher region : the mist afterwards returned, general and dense, 

 and is likely to continue, the wind growing to a strong breeze, with 

 a heavy sea. 



This mist, or fog, was produced by the great heat of the preceding 

 day, when the ice continued to dissolve freely ; and the vapour thence 

 arising, became material for the fog which was condensed by the 

 wind at N.E. : this circumstance deserves attention, and shows the 

 importance to the mariner of his possessing himself of such indica- 

 tions as may enable him to anticipate such clianges. The loss of 

 many a ship every year may be ascribed principally to want of 

 attention, and proper information on this head. 



Procellaria glacialis numerous : colymbus troile in long trains : 

 sterna hirundo and larus eburneus also numerous. 



June 11 : ther. 27°, 34°, 30°: wind N.E., strong breeze : this day 

 continues very cold, the fog still remaining, at intervals clearing 

 partially, and returning thick again, depositing rounded tapering 

 crystals, of a large size, upon the ropes : these crystals are formed by 

 the successive deposition of minute icy particles from the fog : before 

 noon the cloud assumed a greater elevation, so as to leave the horizon 

 clear : the atmospliere cold and dark : P. glacialis and L eburneus. 



June 12 : ther. 32°, 47°, 33°: wind E.N.E., fresh breeze: fog 

 still continuing, strongly illuminated by the sun-light: about 4 p. m. 

 there was some appearance of clearing up, but the fog again resumed
