progress, Mr. Wallace makes the following very remarkable 
deductions ; — “ That a Superior Intelligence has guided the 
development of man in a definite direction. . . . Even 
if my particular view be not the true one, the difficulties I 
have just put forward remain, and I think prove that some 
general and more fundamental law underlies that of natural 
selection. . . . It is probable that the true law lies too 
deep for us to discover it ; but there seems to me to he ample 
indication that such a law does exist, and is probably connected 
with the absolute origin of life and of organisation.” In a note 
to this paragraph he says that some of his critics have 
accused him of believing that “ our brains are made by God 
and our lungs by natural selection.” This would be a legi- 
timate objection if true, for if there be a law underlying that 
of natural selection it is universal; we have but to search 
for its workings, to trace its operations, and we shall find 
them throughout organic nature ; not only in the human 
cerebrum, but in every part of every living thing, both ani- 
mal and vegetal. This is, I think, also Mr. Wallace’s 
belief. 
Mr. St. George Mivart believes in an internal tendency to 
perfection. In his “ Genesis of Species ” the following 
remarks occur: — “Now it is here contended that the rela- 
tionships borne one to another by various component parts 
imply the existence of some innate internal condition, con- 
veniently spoken of as a power or tendency, which is quite 
as mysterious as is any innate condition, power, or tendency 
resulting in the orderly evolution of successive specific 
manifestations. These relationships, as also this develop- 
mental power, will doubtless in a certain sense be somewhat 
further explained as science advances.” 
Even Mr. Darwin, with characteristic candour, writes : — 
“ I now admit, after reading the essay by Nageli on plants, 
and the remarks by various authors with respeCt to animals, 
more especially those recently made by Professor Broca, 
that in the earlier editions of my “ Origin of Species ” I 
probably attributed too much to the aCtion of natural selec- 
tion, and the survival of the fittest. I have altered the fifth 
edition of the ‘ Origin ’ so as to confine my remarks to 
adaptive changes of structure .” 
Professor Owen, while acquiescing in the doCtrine of 
descent, does not accept the theory of natural selection in 
toto. 
Thus there seems to exist a tolerably general sense of in- 
sufficiency in the theory of selection, and the tendency is, in 
a great measure, to return to views approaching those of
