INAUGURAL ADDRESS BEFORE THE BRIT- 

 ISH ASSOCIATION FOR THE AD- 

 VANCEMENT OF SCIENCE."- 



Under the title 'Darwinism' it is con- 

 venient to designate the various work of 

 biologists tending to establish, develop or 

 modify Mr. Darwin's great theory of the 

 origin of species. In looking back over 

 twenty-five years it seems to me that we 

 must say that the conclusions of Darwin 

 as to the origin of species by the survival 

 of selected races in the struggle for exist- 

 ence are more firmly established than ever. 

 And this because there have been many 

 attempts to gravely tamper with essential 

 parts of the fabric as he left it, and even 

 to substitute conceptions for those which 

 he endeavored to establish, at variance with 

 his conclusions. These attempts must, I 

 think, be considered as having failed. A 

 great deal of valuable work has been done 

 in consequence; for honest criticism, based 

 on observation and experiment, leads to 

 further investigation, and is the legitimate 

 and natural mode of increase of scientific 

 knowledge. Amongst the attempts to seri- 

 ously modify Darwin's doctrine may be 

 cited that to assign a great and leading 

 importance to Lamarck's theory as to the 

 transmission by inheritance of newly 'ac- 

 quired' characters, due chiefly to American 

 paleontologists and to the venerated de- 

 fender of such views, who has now closed 

 his long life of great work, Mr. Herbert 

 Spencer; that to attribute leading impor- 

 tance to the action of physiological con-
