and compendious compilation. Beyond this it makes no pre- 

 tensions. 



It will probably be followed by a Manual of Ornithology by 

 the same authour, uniform, like the present, with an extensive 

 series of Manuals on all subjects of Art and Science, which is now 

 in course of publication at Paris. It is to be hoped that in this 

 and all future productions, M. Lesson will avoid the arbitrary 

 changes of names, and the useless multiplication of species, which 

 disfigure the present.

 introduced a species which he has not personally observed, and 

 he has very properly placed it within the power of every one to 

 verify his accuracy, by referring throughout, except in the case of
