 highly important philosophic treatise upon the general subject, which is discussed at length 

 with force and logical consistency; the author's broad views upon this subject had at once a 

 marked influence upon ornithological thought. Variation in general size and proportion of 

 parts, both individual and climatic, are illustrated with numerous tables of measurements. 

 An essay on species and varieties follows. Part IV, List of the Winter Birds of East Florida,
