From the length of the largest foetus recorded in Table 21 and the smallest neonate in Table 22, the length of the new-born sperm whale (at least in the North Atlantic) is seen to range from 371 m. (12 ft. 2 in.) to 4-10 m. (13 ft. 4 in.), and the average length for the five measurements is 3-92 m. (12 ft. 10 in.). Included within this range is the length of a neonate which Wheeler (1933) examined Date Ft. in. M. Sex 11 Aug. J3 3 4-04 6* 12 Aug. 12 8 3-86 0* 12 Aug. 12 9 3-89 6" 14 Aug. 12 2 371 6
