However, to confirm such a supposition I drew attention to the 

 fact that several skulls had been obtained in which the teeth were 

 not only much larger and heavier (according to Dr. Hector 817 and 

 836 grains against 62 to 202 grains, the weight of the female teeth), 

 but moreover were worn down into two lateral facets divided by 

 an acute ridge, so that they had evidently been used. These skulls 

 naturally were considered to have belonged to males. 



On the I3th of June of this year, the news reached me that a 

 Whale had been stranded the day before near the mouth of the 

 Ashley, and though, when reaching the locality, the carcase had 

 already been partly cut into to obtain the blubber, there was a suffi-
