The International Whaling Commission held its fourth meeting in London from June 3 to June 6, 1952. Represented were all of the seventeen member governments except Mexico, namely: Australia, Brazil, Canada, Denmark, France, Iceland, Japan, the Netherlands, New Zealand, Norway, Panama, Sweden, the Union of South Africa, the USSR, the United Kingdom and the United States. The Commission elected Dr. Remington Kellogg (United States) chairman, and Dr. J. G. Lienesh (the Netherlands) vice-chairman. Amendments to paragraph 6, paragraph 8 (c), and paragraph 8 (e) of the schedule of the International Whaling Convention were adopted at the meeting, and entered into force in September 1952. In closing, the Commission agreed that research in new methods of whale marking should be pursued, “but if funds should not allow this, marking by the existing methods should continue. The current catch limits … were extended to the 1952/53 season, retaining the same opening date now in force.”
