320 SCOTT'S LAST EXPEDITION 
between 5 and 9 miles per hour for 23 hours out of the hundred, 
and velocities between 10 and 14 miles in the hour are met with 
during 28-4 per cent. of the time. Higher velocities than these 
occur less frequently, and during every hundred hours the wind 
blows at a greater velocity than 45 miles only during three- 
quarters of an hour.

The figures in Table II. are plotted in Fig. 1, in which the 
thin line curve represents the data for Yarmouth. ‘The curve 
shows clearly how the wind at Yarmouth blows most frequently 
with a velocity of about 10 miles an hour and that the frequency 
of higher and lower velocities falls off very rapidly on either side 
of the maximum. This curve is typical of all stations in the 
British Isles. In every case investigated, calms are of infre- 
quent occurrence, while there is some velocity which occurs most 
frequently. The velocity which most frequently occurs varies 
from station to station, being least—about 5 miles an hour—at 
inland stations and greatest—about 10 to 15 miles an hour—at 
coast stations. 
A similar analysis has been made of the winds at Framheim 
—the winter quarters of Captain Amundsen’s expedition. The 
results are shown in the third column of Table I., and are plotted 
by a broken curve in Fig. 1. It will at once be seen that the
