NATURAL HISTORY OF SOUTH AFRICA 



Whales have been found in the Pliocene deposits 

 on the east coast of England and in Belgium. 



The Right Whale (Bal&aida) is distinguished

 dorsal fin, and by the skin of the throat being smooth. 

 The dimensions of a Southern Right Whale caught

 from point to point i6J feet. 



The name " Right " Whale was given by sailors 

 because it was the right sort of whale, viz. the most 

 valuable to them.

 makers Kop near Port Elizabeth, and on two 

 occasions I witnessed a prolonged fight between 

 two males. The tail and pectoral fins are used as 

 weapons. The tough fin, which is 10 feet long, 

 was raised high into the air ; the Whale brought his 

 body alongside his foe and rolled partly over to

 he brought the fin down on his antagonist with a 

 resounding whack. He then swerved outwards and 

 delivered a terrific blow with his tail. To diminish
