XU PREFACE. 



I also take this opportunity of conveying my best 

 thanks to my friend and colleague, Mr. Children, of 

 the British Museum, for his kind assistance, in re- 

 vising the sheets while the work was printing, and 

 for his many valuable suggestions during its progress 

 through the press. 



A catalogue of the wood engravings has been sub- 

 joined; and also a tabular view of the classification of 

 animals adopted by Cuvier in his ^^ Regne Animal,'' 

 with familiar examples of animals included under each 

 division; both of which I conceived might prove use- 

 ful for purposes of reference. The latter table is re- 

 printed from that which I have given in my " Intro- 

 ductory Lecture on Human and Comparative Physio- 

 logy/' published in 1826, with only such alterations 

 as were required to make it correspond with the se- 

 cond and improved edition of Cuvier's w^ork.
