Abstract
THE annual report for 1932 of the Newfoundland Fishery Research Commission (vol. 2, No. 1, 1933) is now published. A large part is concerned with technical investigations, but in addition there are the results of the hydrographical and biological work, including important researches on fishes and plankton. Much has been done to advance the dried-cod industry and work on the artificial drying of cod and squid and on fish meal production has progressed. The cod liver oil investigations, however, are perhaps the most interesting and it is shown that the younger the fish the less colour there is in the oil, the liver from the young fishes giving an almost colourless oil, that from the old fishes being a deep red or yellow. The depth of colour seems to go with the abundance of vitamin A, so the richly pigmented dark oil is the strongest in vitamin content (see also NATURE of July 1, p. 26).
