EXTERNAL ANATOMY OF INSECTS. 473 
derful and infinite is the diversity which, as you see, in 
this respect they exhibit! Consider the number of the 
organs, the varying forms of each in the different tribes, 
adjusted for nice variations in their uses :—how gradual, 
too, the transition from one to another! how one set 
of instruments is adapted to prepare the food fur deglu- 
tition by mastication; another merely to lacerate it, so 
that its juices can be expressed; a third to lap a fluid 
aliment; -a fourth to imbibe it by suction—and you will 
see and acknowledge in all the hand of an almighty and 
all-bountiful Crearor, and glorify his wisdom, power, 
and goodness, so conspicuously manifested in the struc- 
ture of the meanest of his creatures. You will see also, 
that all things are created after a pre-conceived plan ; in 
which there is a regular and measured transition from 
one form to another, not only with respect to beings them- 
selves, but also to their organs—no new organ being pro- 
duced without a gradual approach to it; so that scarcely 
any change takes place that is violent and unexpected, 
and for which the way is not prepared by intermediate 
gradations. And when you further consider, that every 
being, with its every organ, is exactly fitted for its func- 
tions; and that every being has an office assigned, upon 
the due execution of which the welfare, in certain re- 
spects, of this whole system depends, you will clearly 
perceive that this whole plan, intire in all its parts, must 
have been coeval with the Creation; and that all the 
species,—subject to those variations only that climate 
and different food produce,—have remained essentially 
the same, or they would not have answered the end for 
which they were made, from that time to this.
