- 11 -2 F., registered on the 5th, with ;i light breeze frc>m south by east, is 5-7 lower than the minimum 

 at the ship, noted with a light air from north. The mean wind direction and force is found to have been 

 south-west by south, 2 -6, while at the ship it was east by south, 2 '8. The weather experienced by the 

 travellers was similar to that recorded at the ship, except that at the latter fog was noted on 7 days and 

 mist on 3; but the travellers recorded neither fog nor mist. From the 1st to the 12th December mean 

 temperature on the sledge journey was 17 '6 F., 5'-0 lower than the mean in the same time at the ship. 

 The maximum, 30'2 F., recorded on the 9th, with a light breeze from north-east, is 3' -8 lower than the 

 maximum at the ship, recorded on the llth with the entry "calm." The minimum, 3 '4 F., also noted 

 on the 9th, but with a light breeze from south-west, is 4 '2 lower than the minimum at the ship entered 

 against the 6th, with a gentle breeze from east. The average wind direction and force comes out as 

 south-west, 1 - 7 ; at the ship it was east, 2. Again there was but little difference between the weather on 

 the journey in the last 12 days and that experienced at the ship, with the exception that on 3 days fog 

 was noted at the ship, but no entry of fog occurs in the Journal of the sledge journey for those days. 



At Snow Hill, during the months of September and October, 1903, mean pressure showed a slight Snow 

 increase on the mean of May-August, the result of the 8 a.m. observations giving 29 -16 inches. This is her, J!n:i. 

 0'07 inch higher than the mean 8 a.m. pressure for the corresponding months of the previous year. 

 The highest 8 a.m. reading, 29 '86 inches, was taken on the 7th September, when the wind was moderate 

 from south-south-west ; the lowest, 28 -43 inches, on the 23rd October, when there was a moderate breeze 

 from the opposite point, north-north-east. 



The mean of the 8 a.m. observations for temperature is 9 7 F., in the two months ; the maximum, 

 41 F., occurred on the 27th October, associated with a light air from north-east ; the minimum, - 23 F., 

 on the 1st September, with a light breeze from south-south-west : a range of 64 F. 



The wind's average direction was south-east by south, its average force 2 '5. Strong winds were 

 recorded at 8.m. on 6 occasions, gales on 3. The average cloud amount, 7, is the same as that which 

 obtained during the period May-August. 



At Laurie Island, in September and October, the mean of the observations taken by the Scottish Laurie Island, South 



Orkneys, feptern- 

 Expedition for pressure is 29-288 inches, which is 0-331 inch higher than the mean pressure, during ber-October, 1903. 



the same period, in McMurdo Sound. The highest reading, 30 113 inches, entered against the 3rd October. 

 appears also to have been the highest recorded by the Swedish Expedition during Dr. NORDENSKIOI.D'S 

 stay on Snow Hill Island; the lowest, 28-444 inches, is entered for the 24th of the same month. The 

 range of pressure in October, 1 -669 inches, is found to be the largest for any month at Snow Hill while 

 the Expedition was stationed there. 



The mean temperature, during September and October, was 20 2 F. ; a considerable rise of temperature 

 occurred in October, and the mean for that month was 27' F. The maximum for the two months, 42 F., 

 observed on the 28th October, and the minimum, -25 -8 F., on the 2nd September, show a range 

 of 67 -8 F. 



The mean amount of cloud is estimated as 7 '7. The prevailing winds were westerly; out of 1464 

 entries of wind direction, 366 pertained to winds from north-westward, 216 to winds from northward, 

 210 to winds from westward, and 177 to those from south-westward. But 197 entries were of winds from 

 southward, 110 from south-eastward, and 87 of calms. The average force of the wind is estimated to have 

 been 1'8 ; gales were recorded on 16 hours. Entries were made of snow on 334 hours, sleet on 31 hours, 

 rain on 25 hours, hail on 4, mist or fog on 31. The observations for wind, pressure, and temperature, 

 obtained at Laurie Island and Snow Hill Island, respectively, appear to show that eastward-moving areas 

 of low pressure, after passing Cape Horn, frequently take a path to the north of Joinville Island, and then 

 strike to the south-east, to the westward of the South Orkneys. 



For the summer months of November, December, January, 1903-4, and the first 15 days of February, "Discovery," Nov. 

 1904, the barometer observations taken at McMurdo Sound show a mean pressure of 29 '082 inches, which 1003-4. 

 is 0- 323 inch lower than the mean pressure results for the four months November to February of the 

 previous Summer. 



The highest reading, 29'598 inches, was noted on the 8th December, with a light breeze from north- 

 north-west ; the lowest, 28-508 inches, on the 26th November, with a light air from south. The range of
