and are a stepping-stone to those of the rest of the order, 

 which are all Vermiform and apods. 



Diptera. The majority of this order may be set down 

 as Vermiform, though it is not improbable that some of 

 them bear an analogy to animals that appear far removed 

 from the Annulosa. Thus, the larva of Stratyomis Cha- 

 meleon seems to exhibit no small resemblance to some of 

 the Polypi vaginati in the Acrita subkingdom of Mr. W. 

 MacLeay a . That of Culex and some others is con- 

 structed on a quite different type from the rest, and seems 

 to possess some analogy to the Branchiopod Crustacea. 



Though some of these analogies are more striking than 

 others, yet in almost all that I have stated there is that 

 kind of resemblance that could not be the result of what is 

 called mere chance; and Mr. MacLeay, by first pointing- 

 out this plan of the All-wise Creator, and by laying down 

 the doctrine of analogies in general, as distinguished from 

 affinities in the animal kingdom, has furnished the be- 

 liever with a new argument against those attacks of the 

 infidel, that would render null those proofs of the wisdom 

 and goodness of the Author of nature with which the ani- 

 mal and vegetable creation furnish us ; by affirming most 

 absurdly, and under the most stultifying blindness of 

 mind, that the creatures were in a manner their own cre- 

 ators, their wants under local circumstances stimulating 

 them to efforts that in a long course of years produced 

 all the different forms and organizations that are now to 

 be found in our globe. The affinities and close connexion 

 of beings with each other, so that the ascent from low to 

 high is usually by the most gentle gradations, is the cir-
