This work is tlie result of the labors of one of the members of the Southern 

 Baptist Missionary Society, who resided several years in the Yoruba country, and 

 enjoyed a very favorable opportunity of becoming intimately ace[uainted with the 

 manners, the customs, the mental character, and the language of the people. 



The manuscript was offered to the Smithsonian Institution for publication ; but 

 before it was accepted, it was referred by the Secretary to Professor W. W. 

 Turner of this city for critical examination, and was subsequently placed in. his 

 hands for general revision and scientific arrangement. It was next submitted to 

 the American Oriental Society for an opinion as to its character, and was finally 

 adopted for publication as one of the Smithsonian Contributions to Knowledge on 

 the receipt of the following report ; 



Boston and New Haven, May, 1858. 



The undersigned, having been appointed, by the American Oriental Society, at 

 its meeting held in Boston, May 19th, 1858, a Committee to examine and report 

 upon the Grammar and Dictionary of the Yoruba Language presented to the 

 Smithsonian Institution for publication, have made examination of these works, 

 and declare that they are, in their opinion, true contributions to knowledge, 

 interesting and valuable from the subject and the manner in which it is treated, 

 and that they will be welcomed both by philologists and by those who have at 

 heart the success of philanthropic and Christian effort in Africa.
