BIOLOGICAL TRAINING AND STUDIES. 865 



sliows himself a little cold to matters of moral and social interest 

 whilst absorbed in the enthusiasm of speciality. The combination 

 of minds varying- in bent is found efficacious in correcting these 

 aberrations; and by this combination we obtain that white and 

 dry light which is so comforting to the eye of the truth-loving 

 student, to say nothing as to its being so much stronger than 

 the coloured rays which the work of one isolated student may 

 sometimes have cast upon it from the work of another. It would 

 be invidious to speculate, and I have forborne from suggesting, 

 whether the literary contingent in the conquering though composite 

 army has learnt more from observation of the methods and evolu- 

 tions of the scientific contingent, or the scientific more from the 

 observation of the literary; it is, however, neither invidious nor 

 superfluous to congratulate the general public upon the necessity 

 which these, like other allies, have been reduced to, of adopting one 

 common code of signals, and discarding the exclusive use of their 

 several and distinctive technicalities. Subjects of a universal 

 interest have thus come to be treated, and that by persons now 

 amongst us, in a language universally ' understanded of the people.' 

 I have been careful to include the palaeontologist amongst the 

 scientific specialists whose peculiar researches have cast a helpful 

 and indeed an indispensable light upon the history of the fates and 

 fortunes of our species. But it is not organic science only which 

 anthropology impresses into its service; and it would be the 

 sheerest ingratitude to forget the help which the mineralogist 

 gives us in assigning the source whence the jade celt has come or 

 could come, or to omit an acknowledgment of the toil of the 

 analytical chemist, who has given the percentage of the tm in the 

 bronze celt, or in the so-called 'leaden' and therefore Roman 



''''l am very well aware that many persons who have honoured me 

 by listening to the last few sentences have been thinking that it 

 is at least premature to attempt to harmonise the two classes of 

 evidence in question; and that the best advice that can be given 

 to the two sets of workers severally is, that they should work 

 independently of each other. Craniography is said ^^^ ^^ "';^-
