THE greatest part of the chapter on " Sight in 

 Savages " appeared originally in Longman's Maga- 

 zine ; the chapter entitled " The Plains of 

 Patagonia " is reprinted, with but little alteration, 

 from The Universal Review. Of the other twelve 

 chapters contained in this work, six are based on 

 papers which have appeared in various periodicals.
