Article II. 



Cn the Number of Inhabitants in Hussia, and on the Progress of its 

 Population, according to the Statements made hy order of Go- 

 vernment. By C. T. Herrman.* 



The statement of the population of any country is of itself an 

 object of considerable interest, because it proves the degree of 

 comfort and happiness which the inhabitants enjoy, — makes ui^ 

 acquainted with the degree of power which the government is 

 capable of exerting ; but as far as Russia is concerned, this question 

 ]»as acquired an additional degree of interest, in consequence of the 

 very different statements that have been published respecting her 



Eupulation. Schlozer states t that during liis residence in Russia 

 e represented to his superiors how surprizing it was tliat the total 

 number of inhabitants was unknown, and that the discrepancies on 

 th'is subject appeared incredible : and B. F. I. Hermann aflirnis, J; 

 that there is no state in Kuropc in which the data for determining 

 the population are so different. The author of Essay on the Com- 

 merce of this Empire (Le Clerc) admits 14' millions of inhiibitants; 

 Voltaire, Marshal, and Williams, 18; I^veque, 19. Busching, 

 in the first edition of his Geography, makes the number 20 ; in his 

 last edition, 30 ; Albaum, 22; Coxe, 23 ; Sussmilch and Ebeling, 

 24; Crome, 25; PIcschtchecf, 2(;x; Hupel, 28; Bcausoble, 30;
