Whales less than 19-0 m. long. The similarity of the results obtained for the males and resting females indicates the general conclusion that whales are fatter at the end of the season at South Georgia than they are at the beginning and that a decrease in blubber thickness takes place in South African waters. The increase in average blubber thickness of adult whales at South Georgia should be due to good feeding and fattening in that neighbourhood, where the food, as already explained, is available in abundance. The possibility might be suggested that the increase in fatness may be due to increasing numbers of fat whales arriving in South Georgian waters from other, apparently richer, feeding grounds as 15
