198 ON THE EFFECTING OF 



be made of a short delay in Hickson's Bay, which we 

 approached on the 5th of July, a very valuable acquisition 

 might be obtained of eider down ; the ducks of that species 

 frequenting the low islands on the north side in countless 



masters, in going so far in that direction, was to intercept the whale 

 in his progress east and west : and in this respect not one of them had 

 success, the ships which remained the .most to eastward having killed 

 a good many. 



Latitude observed at noon 75° 8' N. : lams eburneus, and co- 

 lymbus glocitans, few throughout this day : procellaria glacialis also 

 few in number : it would seem as if these birds had proceeded to the 

 southward warned by the indications of the season, which, to human 

 observation are not so discernible as to those migratory animals. From 

 the great number of the monodon monoceros seen and killed in view 

 of the Linnsean Isles, I have marked the place upon the chart 

 " Unicom Bay." At eight p. m. some very light cutus appeared in the 

 zenith, and towards S.E. : larus maximus and colymbus giyUe came into 

 view frequently in the course of the evening : the water in Unicorn 

 Bay is of the colour of the bay -leaf, and crowded with moUusca : the 

 tide setting strongly, as heretofore, observed north and south by 

 compass : at a later hour the cirrus changed into cirrocumulus, evi- 

 dently communicating with loose patches of ciirostratus lower down : 

 ship laid to by the flaw, as on the 17th current. 



July 21 : ther. 34°, 48°, 42° : wind, a perfect calm : at three a. m. this 

 morning a most magnificent display of radiation occurred, of whicli a 

 sketch has been attempted. (See Plate XVI.) The ciirus radiation
