130 REPORTS ON THE STATE OF SCIENCE.—1914. 
It may be useful to compare these results with those of Burfield, 
who gives similar statistics for the year 1911:—

As all the figures for 1913 are epic smaller than the corre- 
sponding figures of Burfield for 1911, it suggests the probability that 
the larger whales are being killed off, although it would be useful 
to have the figures for other years in ‘order to. verify the diminution 
in size which appears to be taking place. 
Blue Whales (B. sibbaldiit, Gray). 
All the Blue Whales taken in the 1913 season were brought in 
during our stay :—

Comparing these also with Burfield’s figures * for the same species 
we have:—

True gives 72 ft. as the minimum for mature females, but our 
second specimen (70 ft. 7 in.) had a feetus 8 ft. long, and was 
therefore an adult animal. (True’s figure was based upon two speci- 
mens only.) 
Sperm Whales (Physeter macrocephalus, L.). 
Ten Sperm Whales were taken in 1913; of these six were taken 
after our arrival, and all the specimens were males.
