inent of the book, or to remove the Whales and other 
Cetacea from the Fishes. I have therefore placed the 
Monkeys and their allies at the end of the terrestrial 
Mammalia, instead of at the beginning ; and commenced 
the book of Fishes with the Cetacea. 
I have corrected the whole of the descriptions of the 
animals, adding to or taking from as appeared necessary 
to bring the whole down to the present state of Zoological 
knowledge; and in the Introduction I have added a 
Sketch of Cuvier's Systematic Arrangement of the Animal 
Kingdom to that of Linnaeus, which was given in the 
previous editions.
