AtFrepD RussELL Wa Lace, in the Contemporary Review of 
August, 1908, p. 140, in an article on ‘The Present Posi- 
tion of Darwinism,’ writes as follows: 
‘In conclusion, I would suggest to those of my readers 
who are interested in the great questions associated with the 
name of Darwin, but who have not had the means of study- 
ing the facts either in the field or the library, that in order 
to obtain some real comprehension of the issue involved in 
the controversy now going on they should read at least one 
book on each side. The first I would recommend is a 
volume by Mr. R. H. Lock on “ Variation, Heredity and 
Evolution” (1906) as the only recent book giving an account 
of the whole subject from the point of view of the Mendelians 
and Mutationists. When they have mastered this, I ask 
them to read my own book on “ Darwinism” (1901), which, 
though published before Mendelism became prominent, 
gives some idea in popular language of the vast range of 
subjects which Darwinism explains, and adduces a sufficient 
body of facts to show the inadequacy of the whole series of 
phenomena yet made public. 
‘Having read these two works and again considered the 
arguments adduced in this article, I leave them to form 
their conclusions as to whether Darwinism is or is not an 
“unsuccessful hypothesis.”’’ 
‘ALFRED R. WaLLace.’
