The thermometer iu 0 at uoon this day, stood as high as 61° on board, but wlien suspended from a pole perfectly detached, at + 60°. The day calm and cloudless; objects upon the horizon were much distorted by refraction, causing the ice to assume a great variety of shapes, but generally of innumerable perpendicular columns, su that the ships appeareti surrounded by a distant wall of ice, making the distant hurizon to appear at an clevuiion instead nf a de- pression, as the observations shew. From the mast-head the appearance of the ice was very singular, for besides the distant horizon having so great an elevation, yet the ice at about a mile distance from the ships, appeared considornhly depressed, causing the surface of the ice to be concave, gradually sloping down from the ships, and becoming elevated as it approached the horizon. The ships were closely beset with ice, and no water in sight. By a mean between the obsenations of Captain Parry and Mr. Bushnan, on the ice with false horizon, the apparent altitude of the 0's was 48° 46' 47'close by the ship's side; at the same time the same limb of the sun was observed by myself from the ship's gangway to be 48° 43' 58" above the visible horizon, (which was a closp and weU-dofined line of ice.) The thermometer freely suspended in the O + 74°
