JULY, 1911 continued. 



July 8th, 1911 continued. 



10 p.m. Calm. Sky fairly clear but inclined to cloud over. Glaciers obscured. Halo of 

 22 degrees round the moon. Temperature falling steadily. Barometer steady. 



12 midnight. Overcast again, with light indefinite snow-cloud through which the moon 

 shines dimly. A few spicules of snow falling. Temperature fall arrested. 



July 9th, 1911. 



4 a.m. Southerly wind of force 1. Cloudy, clearing, but still hazy. Halo of 22 degrees round 

 the moon. Glaciers obscured. Temperature falling slowly but steadily. Barometer 

 steady to failing. 



10 a.m. Southerly breeze of force 2 to 3. Overcast. GUciers obscuied. Temperature 

 oscillating. Barometer steady. 



10 p.m. Slight southerly wind all day. Temperature steady. Overcast with indefinite cloud 

 haze through which the moon has been shining, sometimes surrounded with a pale white 

 halo of 22 degrees. Barometer falling slightly. 



12 midnight. Wind increasing from the S. Temperature rising. 



July \Mh, 1911. 



2 a.m. A very gusty wind still blowing from the S.. bringing a little flocculent snow consisting 

 of aggregations of verv tiny spikes and grains. 



OO O i/ </ J. 



4 a.m. Wind swung to W.S.W. Very gusty, force 3 to 7, with calm lulls ; sometimes these 

 latter are of 3 to 4 minutes' duration. Overcast. Temperature oscillating. Barometer 

 falling very slowly. 



10 a.m. S.E. wind of force 5 to 6. Overcast. Glaciers obscured. Temperature risen several 

 degrees. Barometer steady. 



4 p.m. The wind has varied continually to-day, swinging from S. to S.E., to S.W. to W.S.W., 

 and to S. again, and varying in force from 4 to 7 to 1 to 3, with calm lulls between. There 

 has been a corresponding oscillation in temperature through a range of a dozen or more 

 degrees. Luckily, the thermograph is working all right now and the record last week is a 

 sight for the gods. This morning the oscillations have been so frequent and abrupt that 

 the record is in places reduced to a broad blot. The sky has cleared near the zenith, but 

 it is still thick to the S. 



10 p.m. Calm to S.E. airs. Cloudy. Clear near the zenith, except for a few scud-clouds, 

 but thick to the S. Slight noise from behind Cape Adare might be pressure or wind. 

 Oscillations in temperature continue. 



Temperatures to-day are as follows: 4 a.m., 11-6F. ; 6 a.m., -- 4-8 ; 8 a.m. ; 

 10-5; 10a.m., 2-8; noon, 12-8; 4p.m., 1-9; 6p.m., 10-1; 8p.m., 2-2; 

 10 p.m.,'-- 12-0. 



These changes are most extraordinary. They correspond roughly with the estimations 

 of wind force. Strong wind and high temperature, and vice-versa, with the single 

 exception of the 6 a.m. observation. It is easy to understand the sudden rise of temperature 

 with the increase of southerly wind, what one cannot easily explain is a drop of 10 F. 

 when the wind decreases in force for such a short space of half an hour to one hour. I 

 suppose it is the influence of the cold rock, but that seems unusual. Barometer is steady. 



July \\th, 1911. 



4 a.m. Southerly airs. Cloudy but clearing. Slightly hazy. Broad indefinite white halo 

 round the moon, halo of 22. Glaciers clear. Temperature oscillating. Barometer steady 

 to falling. 



10 a.m. Calm. Clear. Glaciers clear. Barometer steady and temperature falling. Fine 

 prismatic sky to the N.
