natural selection” (p. 49). 
I do not quite see, myself, how, if the action of 
natural selection is certain, the occurrence of evolu- 
tion is only probable; inasmuch as the development 
of a new species by natural selection is, so far as 
it goes, evolution. However, it is not worth while 
to quarrel with the precise terms of a sentence 
which shows that the high water mark of intelli- 
gence among those most respectable of Britons, the 
readers of the Quarterly Review, has now reached 
such a level that the next tide may lift them 
easily and pleasantly on the once-dreaded shore of 
evolution. Nor, having got there, do they seem 
likely to stop, until they have reached the inmost 
heart of that great region, and accepted the ape 
ancestry of, at any rate, the body of man. For 
the Reviewer admits that Mr. Darwin can be said 
to have established : 
“That if the various kinds of lower animals have been 
evolved one from the other by a process of natural generation 
or evolution, then it becomes highly probable, @ priori, that 
man’s body has been similarly evolved; but this, in such a 
case, becomes equally probable from the admitted fact that he is 
an animal at all”’ (p. 65). 
From the principles laid down in the last sen- 
tence it would follow that if man were constructed 
upon a plan as different from that of any other 
animal as that of a sea-urchin is from that of a 
whale, it would be “equally probable” that he
