August, 1902, which was the lowest reading recorded during the "Discovery's"' stay in tin- Antan-tir 

 regions. 



As regards temperature, the Winter of 1903 was rather more severe than the Winter of the previous 

 year. The mean temperature, for the four months under notice, is found to have been as low as 

 - 16"9 ., whereas the mean temperature of the winter months, May to August, 1902, was - 13'3 F. 



Cape Armitage. The mean temperature at Cape Armitage during the months under notice, obtained from 203 observations, 



generally taken twice a day, i.e., at about noon and 4 p.m., comes out as -28- 5 F. The range of 

 temperature during these months was 71 -2 F. at Winter Quarters and 76' 2 F. at Cape Armitage. The 

 maximum temperature of 17 F. at Winter Quarters was registered on the llth June, when there was a 

 light breeze from east, and this is 2 F. lower than the maximum reading of the corresponding period of the 

 previous year. The maximum temperature observed at Cape Armitage was not higher than 8 '5 F. 



The minimum for the period, -54 -2 F., registered on the 30th July at Winter Quarters, in a calm, is 

 3 '7 F. lower than that of the previous year. At Cape Armitage the minimum temperature of the four 

 months, - 67 -7 F., registered on the 16th May, is as much as 5 -7 F. lower than the lowest registered in 

 the two months July, August, 1902, which are the only months for which observations are available for 

 comparison in that year at Cape Armitage. 



As regards the weather experienced at Winter Quarters in the four 'winter months of 1903, 52 days 

 were cloudy, 19 overcast; but blue sky was recorded on 52 days. Snow fell on 40 days; the weather WHS 

 misty on 54, foggy on 21. Strong winds blew on 40 days, and attained force 8, and upward, on 24 days. 

 Aurora was observed on 76 days. 



Out of 1476 observations of wind direction, 29 2 per cent, were of winds from an easterly direction, 

 17 - 8 per cent, of winds from a north-easterly direction, 27 '5 per cent, were of calms, and 4 '2 per cent, of 

 variables. 



Snow Hill Island, At Snow Hill Island, during the four months May to August, 1903, the mean pressure at 8 a.m. 



19 ^ '' increased to 29-13 inches from 29-05 inches, the mean for the two previous months. The maximum 



8 a.m. pressure, 30-01 inches, occurred on the 12th May, during a calm; the minimum 8 a.m. pressure, 



28-25 inches, on the 3rd June, when a strong south-west wind was blowing; thus a range of 1'76 inches 



is shown for the period. 



A mean temperature of - 1 2 F. is found from the 8 a.m. observations. A maximum of 40 F. relating 

 to the 31st May, and a minimum of - 32 F. to the 20th June, both associated with a calm, give 72 F. as 

 the range of temperature at 8 a.m. a large range. 



The average direction and force of the wind, estimated at 8 a.m. during the four months, is found to 

 have been south, 2-7; the average amount of cloud 7. 



On 18 occasions, at 8 a.m., the wind was estimated at force 6-7, and on 5 occasions as force 8-10. 



Laurie Island, South The results of observations made at Laurie Island during the four months May to August, 1903, exhibit 

 August, 1903. a mean pressure of 29-250 inches, being 0-027 inch higher than the mean pressure at McMurdo Sound 

 for the same months. The highest pressure during the period, 30-013 inches, observed on the 13th May, 

 is 0'048 inch lower than the "Discovery's" lowest, covering the same months; the lowest pressure, 

 28-231 inches, observed on the 3rd July, is 0'069 inch lower than the "Discovery's" for the same months. 

 The range of pressure during the period, 1 -782 inches, is 0-021 inch larger than the range at McMurdo 

 Sound during the same period. 



The mean temperature in these months is found to have been 15 4 6F. ; a maximum of 46 F., 

 registered on 31st May, and a minimum of - 26 F. on the 19th June, show a range of 72. 



Cloudy weather appears to have prevailed during the four months, the mean amount of cloud being 

 estimated at 7 -5. Snow fell on 765 hours, sleet on 29 hours, rain on 152, and hail on 21. 



Fog, or mist, is entered on 144 hours. The mean force of the wind, as estimated, is 2 1 ; no gales were 

 experienced in May or June, but in July and August winds of force 8, and above, are noted on 71 hours. 



Out of 2952 observations of wind direction made during the period, 392 were of northerly winds, 732 

 of north-westerly, 463 of westerly, 308 of south-westerly, and 405 of southerly. There were 172 obser- 

 vations <if calms, and 25 of variables; so that only 455 observations were of winds from the north-east, 

 east, and south-east directions, and of these not more than 109 were of winds from eastward.
