NOTES ON THE TABLES 377 



NOTES ON THE TABLES 



Table i (p. 361) shows the number of Fin whales killed in each group for each season's marking. 

 The few whales marked by the 'Discovery II' are omitted from this and all other tables but those 

 marked by certain German whaling expeditions which co-operated with the Discovery Committee 

 in 1938-39 are included. The total numbers of whales effectively marked during each season, shown 

 in the first column of figures, are calculated on the basis used by Rayner (1948). Only those actually 

 recorded as hits, together with 'misses' and 'possibles' later recovered have been counted. No 

 duplicate hits, no ' possible hits ', and no marks recorded as protruding, except when such a protruding 

 mark has been returned, are included in the total. In the other columns are given the numbers 

 of marked whales reported killed during the same season as they were marked and during sub- 

 sequent seasons. The single whale recovered in warm waters in the southern winter during the 

 period between the Antarctic whaling seasons appears in 2^-group. The whale marked in warm waters 

 in October 1937 and recovered in the Antarctic appears in n-group. The final column gives the 

 number of marked whales recovered up to the end of the 1951-52 Antarctic whaling season, for each 

 of the marking seasons. 



Table 3 (p. 370) gives the same data for Blue whales. No marks have been returned in 6-group 

 to 10-group inclusive. 



Table 5 (p. 374) gives the numbers of whales of each species effectively marked within the boundaries 

 of Areas I-IV in each marking-season. The totals are arrived at in the manner described for Table 1 

 above. The marking in the 1938-39 season was done by the German expeditions. 



Tables 6 and 7 (pp. 378, 380) present a complete list of returned marks for Blue and Fin whales. 

 The dates and positions of marking and of recovery are shown, and the length of the whale carrying 

 the mark, measured when captured, together with its sex, when these details have been given with 

 the returned mark. In a few cases no data' have been supplied with the returned marks, and in others 

 only approximate dates and positions of recovery are possible. 



The marks are arranged in groups corresponding with those in Tables 1 and 3. Within these 

 groups they are arranged in chronological order of the dates of firing, irrespective of the position of 

 marking. When two or more marks were fired on the same day, they are arranged in numerical order. 



The prefix ' G ' signifies a mark fired by the German expeditions in the 1938-39 season. In those 

 instances where two marks have been recovered from one whale, the two final digits of the number 

 of the second mark are given after a stroke, it being understood that the preceding digits are the same 

 as the corresponding digits of the accompanying mark. Two exceptions occur, one where the two 

 marks are numbered 656 and 1229, and one where three marks were recovered, numbers 1183, 1205 

 and 1210. This convention is also used in the text.
