The "Scotia" was cruising in the Weddell Sea during March, 1 ( JO-1, between I he parallels of (JO ''>!' S., ''Scotia," Mnrcli, 

 and 71 J 1' S., and the meridians of 10 li 1 ' W. anil 23 5,')' W. Slie was in her most southerly position, in 

 latitude 74" 1' S., longitude 22 0' W., near the ice hairier of the land discovered by Mr. l!i;n K and 

 named by him Coat's Land, on the 7th of the month and remained in the locality until the 12th. 



From the 7th to the 9th a hard easterly gale is said to have been experienced, accompanied by thick 

 driving snow, and associated with a low temperature. 



The hourly observations obtained during the month of March, 1904, on board the "Scotia" show a 

 mean pressure of 29'007 inches, and at Laurie Island the mean pressure is found lo have been 

 29' 106 inches during the same time. The highest barometer reading recorded on board the "Scotia" 

 during the month, 29 '708 inches, was taken on the 12th in latitude 74" 1' S., longitude 22 0' \V., when 

 near the ice barrier, a light air from south-south-west stirring at the time. The highest reading at Laurie 

 Island during the month, 29 '71 3 inches, was taken on the llth. 



The lowest reading noted on the "Scotia" during the month, 28 '142 inches, was taken on the 27tli, in 

 latitude 6(V 57' S., longitude 13" 13' W., with a moderate breeze from north ; the lowest at Laurie Island, 

 28'280 inches, noted on the 8th, was associated with a light breeze from south-east. The "Scotia's" 

 range of pressure, 1'56G inches, is therefore 0'133 inch larger than the range of pressure at Laurie 

 Island in March, 1904. 



It is worth noting that although the "Scotia's" highest barometer reading was observed when the vessel 

 had reached her position farthest south, yet mean pressure in the Weddell Sea, between the 60th and 74th 

 parallels of south latitude and the 10th and 28th meridians of west longitude during March, 1904, was 

 nearly a tenth lower than the mean pressure at Laurie Island in that month. Moreover, from the 1st to 

 the 10th of the month, when the "Scotia's" mean latitude was 72 39' S., she recorded barometer readings 

 which show a mean pressure of 28 '789 inches, while pressure at Laurie Island was 29 '075 inches, or 

 0-286 inch higher. Again, from the llth to the 20th, the "Scotia," in an average latitude of 72 22' S., 

 recorded observations for pressure giving a mean of 29 '200 indies against 29-181 inches, the mean of the 

 barometer observations recorded at Laurie Island, which is only 0' 019 inch lower than the "Scotia's" 

 mean pressure for the period. There seems, therefore, no evidence to show that pressure decreased in the 

 higher latitudes visited by the Scottish Expedition in the Weddell Sea; the reverse appears to have 

 obtained. 



Observations for temperature made on board the "Scotia" during the month of March, 1904, yield a 

 mean of 24 - 9 F. The maximum temperature, 32 F., was registered on the 31st, on which date at noon, 

 G.M.T., she was in latitude 60 37' S., longitude 12 3 16' W., when the wind was blowing with fresh to 

 strong gale force from north; the minimum, -0 - 3 F., on the 12th, on which date at noon, G.M.T., she 

 was in latitude 74 1' S., longitude 22 0' W., when there was no wind. 



At Laurie Island the mean temperature is found to have been 32" '4 F. during the time; the maximum 

 temperature recorded, 39''9 F., relates to the 4th; the minimum, 20"'8 F., to the .'{.1st. 



The range of temperature exhibited by the observations of the "Scotia" in the Weddell Sea, 32' '3 F., is 

 therefore, 13 2 F. larger than the range shown by the observations taken at Laurie Island. 



The "Scotia" had cloudy weather in the Weddell Sea; the average amount of cloud, as estimated, is 

 found to have been 8 '7. 



The prevailing winds were from westward and north-westward. Out of 743 observations of wind. 142 

 were of those from north-westward and 136 of winds from westward. But 121 of the observations related 

 to winds from northward, 96 to those from north-eastward, 92 from eastward, and 43 were of calms and 

 variables. The mean force of the wind, as estimated, is found to have been 2'8.
