From the purely human point of view this table shows the disagreeableness of the climate 

 in McMurdo Sound. Out of twenty months there were only four in which there were less than 

 20 per cent, of hours with snow or drift. In twelve months the percentage of snow and drift 

 was more than 25 per cent, and in three it was over .50 per cent.
