ain and the relief is almost
instantaneous.

This very satisfactory condition of inside air must be a highly
important factor in the preservation of health.

I have to-day regularised the pony 'nicknames'; I must leave it to
Drake to pull out the relation to the 'proper' names according to
our school contracts! [24]

The nicknames are as follows:

James Pigg Keohane
Bones Crean
Michael Clissold
Snatcher Evans (P.O.)
Jehu
China
Christopher Hooper
Victor Bowers
Snippets (windsucker)
Nobby Lashly

_Friday, June_ 2.--The wind still high. The drift ceased at an early
hour yesterday; it is difficult to account for the fact. At night
the sky cleared; then and this morning we had a fair display of
aurora streamers to the N. and a faint arch east. Curiously enough
the temperature still remains high, about +7 deg..

The meteorological conditions are very puzzling.

_Saturday, June_ 3.--The wind dropped last night, but at 4
A.M. suddenly sprang up from a dead calm to 30 miles an hour. Almost
instantaneously, certainly within the space of one minute, there was
a temperature rise of nine degrees. It is the most extraordinary
and interesting example of a rise of temperature with a southerly
wind that I can remember. It is certainly difficult to account for
unless we imagine that during the calm the surface layer of cold air
is extremely thin and that there is a steep inverted gradient. When
the wind arose the sky overhead was clearer than I ever remember to
have seen it, the constellations brilliant, and the Milky Way like
a bright auroral streamer.

The wind has continued all day, making it unpleasant out of doors. I
went for a walk over the land; it was dark, the rock very black,
very little snow lying; old footprints in the soft, sandy soil were
filled with snow, showing quite white on a black ground. Have been
digging away at food statistics.

Simpson has just given us a discourse, in the ordinary lecture series,
on his instruments. Having already described these instruments, there
is little to comment upon; he is excellently lucid in his explanations.

As an analogy to the attempt to make a scientific observation when
the condition under consideration is affected by the means employed,
he rather quaintly cited the
