The opinion that most of the Blue whales taken on the South Georgian grounds during the seasons studied, were on passage to and from other feeding grounds also gathers strength from these figures. It will be seen from the small number of observations obtained at the South Shetlands at mid-season (p. 271) that the percentage of Fin whales with thick film was exceptionally high, while the percentage infection was quite normal. It follows that at the time the
