6 ORIGIN OF SPECIES. 
Thus we find the author of “Vestiges of Creation” 
saying: ‘Is it conceivable, as a fitting mode of ex- 
ercise for creative intelligence, that it should be con- 
stantly moving from one sphere to another, to form 
and plant the various species which may be required 
in each situation at particular times ?—Yet such is 
the notion which we must form, if we adhere to the 
doctrine of special exercise.” (p. 120): 
Well let us see. The heat and leht of the sun is 
absolutely necessary, for the growth of wheat ; and 
the farmers of an entire continent have prepared the 
ground, and sown the grain in especial ‘reference to 
the operation of these elements. Does the sun find 
it necessary to give its attention first to one farm 
and then to another, in order to perfect each crop ? 
And can it be supposed that the sun’s Creator has 
any less range and potency of creative action ? 
I have already said, that so far as all animal forms 
within the historic period are concerned, a receptacle 
or matrix has been used, and therefore found neces- 
sary in their creation. It may be added, that there 
is no fact known to science, or any reason by analogy — 
by which the inference is warranted, that any differ- 
ent mode has been adopted in the production of the 
ancestral types of the several species which have ex- 
isted, and still exist. This theory of creation, by 
Influx and incipient ova or matrices, receives re-_ 
markable confirmation in those facts in the history 
of creation, which are conceded to be true, and to
