22. Of the progressive scale of animals, rising 

 through many gradations from those most imper- 

 fectly organized to man. 



The second volume was published by his son, 

 the present Mr Alexander Smellie, in 1799, four 

 years after his father's death. It comprises nine 

 chapters, and had been entirely completed, ready 

 for the press. 



CHAP. 1. Gives a concise view of the utility 

 of method or arrangement in every department 

 of science, and points out methodical arrange- 

 ment into tribes and families, or what are usually 

 called orders and genera, as being evidently 

 founded in nature, both in the animal and veget- 

 able kingdoms. To this he has appended a 

 concise, historical, and characteristic account of 

 the writings and arrangements of the principal 

 ancient and modern naturalists, beginning with 

 Aristotle and ending with Pennant. 



2. On the multiplication and construction of 

 the species ; and the theories of various authors, 

 ancient and modern, are explained and com- 

 mented on. 



3. Of mules, or the anomalous productions of 

 nature. 



4. Of the varieties of man in different regions 

 of the globe ; and of the varieties in manners and 

 customs, religion, war, agriculture, marriages, 

 burials, government, arts, manufactures, &c. of 

 the different nations of the world.
