( 433 ) p. 351. Tacitus, in his speculations on the population of Britain, 

 (Agricola, cap. ii.) distinguishes finely between that which is due to the influ- 

 ence of climate, and that which in the immigrating tribes is hereditary in 

 race, and not susceptible of change. " Britanniam qui mortales initio colue- 

 runt, iudigenae an advecti, ut inter barbaros, parum compertum. Habitus 

 corporis varii, atque ex eo argumenta ; namque rutilae Caledoniam habitantium 

 comae, magni artus Germanicam originem adseverant. Silurum colorati 

 vultus et torti plerumque crines, et posita contra Hispauia, Iberos veteres 

 trajecisse, casque sedes occupasse fidem faciunt : proximi Gallis, et similes 

 sunt : seu durante originis vi ; seu, procurrentibus in diversa terris, positio cceli 

 corporibus habitum dedit." Respecting the persistency of types and configu- 

 ration in the warm and cold regions of the earth, and in the mountainous 

 districts of the New Continent, see my Relation historique, T. i. p. 498 

 503 ; T. ii. p. 572574.
