bar-October, J902. 



From the 19th February to the 5th March, 1904, the "Discovery," homeward bound from McMurdo 

 Sound, recorded winds from between east-south-east and west-north-west, round by south, but principally 

 from between south-east and south-west to the 66th parallel. The " Morning," from the 1st to the 

 25th February of that year, while in McMurdo Sound and traversing the same route, had winds from 

 between east-north-east and west-south-west round by south, but principally from east-south-east. Thence 

 to the 50th parallel both vessels experienced westerly winds, chiefly from between west-south-west and 

 north-west. 



Cruising in the Weddell Sea, during February and March, 1903, between the parallels of 60 S. and 

 68 S., the Scottish National Antarctic Expedition in the " Scotia " recorded 427 observations of wind 

 from north to north-east and 255 from south to south-west out of a total of 1142 wind observations ; and 

 from the 21st February to the 20th April, 1904, between the parallels of 45 S. and 72 S., 767 south-west 

 to north-west winds were recorded and 309 north to north-east winds out of a total of 1440 wind 

 observations. 



At Snow Hill, the mean of the barometer observations recorded in September and October, 1902, at Snow Hill, Septem- 

 8 a.m., by the Swedish Expedition, is found to be 29 09 inches. The results for this period compared 

 with those of the period May-August show a diminution of mean monthly pressure at this station of 

 - 37 inch from June to October, but a recovery of pressure of 0'15 inch from August to September. 

 The highest 8 a.m. pressure, in September and October, was recorded on the 29th September and was 

 29 - 77 inches, a moderate breeze from south-south-west being noted at the time ; the lowest pressure in 

 the 2 months, 28 -38 inches, was recorded on the 14th September and was associated with a gentle breeze 

 from the same direction. These extremes show a range of pressure at 8 a.m. of 1 39 inches. 



The mean of the 8 a.m. observations for temperature during these 2 months is 7 1 F. ; the maximum 

 8 a.m. temperature, 38 F., was registered on the 16th September, when there was a light air from north ; 

 the minimum, - 27 F., on the 1st September, when there was no wind, and again on the 2nd September, 

 when there was a light air from north-east. The range of temperature at 8 a.m. therefore was 65. 



The prevailing wind during this period was from south by west, and this was the prevailing wind in 

 March and April and from May to August inclusive. The average force of the wind at 8 a.m. is found to 

 have been 3-4; the number of strong winds recorded at 8 a.m. was 10; the number of gales 7. The 

 mean amount of cloud was 8. Dr. NORDENSKIOLD mentions that a strong, warm wind from north-west 

 set in about the middle of September and lasted for a few days, and that it drove the ice from the land ; 

 but that gales and cold returned at the end of the month. 



At the "Discovery's" Winter Quarters during the summer months November, 1902, to February, 1903, 

 inclusive, a mean pressure of 29 '405 inches obtained. 



The highest barometer reading, 30 '112 inches, was taken on the 22nd November during a calm; the 

 lowest, 28-758 inches, on the 23rd February, also during a calm. A mean temperature of 18 -1 F. 

 obtained during the period, and the range of temperature was 48 -5. The maximum temperature was 

 39 F., and it was registered on two occasions : on the 26th December, in a calm, and on the 8th January, 

 with a light air from east-north-east. The minimum temperature, -9 - 5 F., is entered against the 

 24th February, with a light air from north. The winds were principally from between north and south- 

 east. Out of 1440 observations of wind recorded during the four months, when referred to 8 points of 

 the compass, 18 3 per cent, come under the head "north," 28- 3 per cent, under the head "east," 10 '2 per 

 cent, under " north-east," and 12' 7 per cent, under " south-east." But 19 3 per cent, of the observations were 

 under the head " calms'' and 3 - 5 per cent, under "variable." The remaining 7 - 7 per cent, of the obser- 

 vations were of winds principally from south and north-west. The mean force of the wind as estimated 

 was nearly 3, and no gales were recorded. Blue sky was noted on 25 days ; the weather was cloudy on 

 61 days, overcast on 34, misty on 14, foggy on 10. Snow fell on 37 days. 



At Cape Armitage only three observations for temperature were recorded during the four months Cape Armitage, De- 

 November-February, 1902-3. On the 17th December a reading of 28 F. was noted, and the maximum 

 temperature at Winter Quarters on that day was 27 - 2 F. ; on 5th November the minimum thermometer 

 registered - 14 F., and the minimum temperature in the screen at Winter Quarters registered on the 

 same day was 4 4 F.
