Abstract
AFTER a considerable amount of experimenting the Discovery expedition evolved a satisfactory device for marking whales, in the form of a stainless steel tube 10 in. long that can be fired from a 12-bore gun. In the four seasons 1934–38 a total of 5,219 whales of six species was considered to be satisfactorily marked. G. W. Raynor (Discovery Reports, 19; 1940) describes the methods of marking, the data provided by the marks so far returned and discusses their significance. Of the three main species to be marked, the Blue, the Fin and the Humpback, there have been 187 returns out of 1,513 marked.
