PEEFACE 



The numerous alterations I have made in this new 

 edition of the 'Tropical World,' both by the attentive 

 revision of its former contents, and the addition of new 

 chapters descriptive of the chief characteristics of the 

 various tropical races of man ; as well as the care I have 

 taken to condense as much information as possible within 

 narrow limits, will, I hope, justify my assertion that I 

 have done my best to please indulgent readers, and to 

 merit the favourable verdict of severer critics.
