UNITY OF THE DEITY. 293 



our own, and which variation, in truth, demonstrates, not an 

 interruption, but a continuance of the same exquisite plan ; 

 for it is the adaptation of the organ to the element, namely, 

 to the different refraction of light passing into the eye out of 

 1 denser medium. The provinces, also, themselves of water 

 and ea.'th, are connected by the species of animals which 

 ir.habit both ; and also by a large tribe of aquatic animals, 

 which closely resemble the terrestrial in their internal struc- 

 ture : I mean the cetaceous tribe, M^iich have hot blood, 

 respiring lungs, bowels, and other essential parts, like those 

 of land-animals. This similitude surely bespeaks the same 

 creation and the same Creator. 



Insects and sliell-jish appear to me to difier from other 

 classes of animals the most widely of any. Yet even here, 

 besides many points of particular resemblance, there exists 

 a general relation of a peculiar kind. It is the relation of 

 inversion — the law of contrariety : namely, that whereas, 

 in other animals, the bones, to which the muscles are at- 

 tached, lie williiii the body, in insects and shell-fish they lie 

 on the outside of it. The shell of a lobster performs to the 

 animal the office of a hone, by furnishing to the tendons that 

 fixed basis or immovable fulcrum, without which, mechani- 

 cally, they could not act. The crust of an insect is its shell, 

 and answers the like purpose. The shell also of an oyster 

 stands in the place of a bone ; the bases of the muscles be- 

 ing fixed to it in the same manner as, in other animals, 

 they are fixed to the bones. All which, under wonderful 

 varieties indeed, and adaptations of form, confesses an imi- 

 tation, a remembrance, a carrying on of the same plan. 



The observations here made are equally applicable to 

 plants ; bui, I think, unnecessary to be pursued. It is a very 

 striking circumstance, and also sufficient to prove all which 

 we contend for, that, in this part likewise of organized na- 

 ture, we perceive a continuation of the sexual system. 



Certain however it is, that the whole argument for the 

 divine unity goes no further than -to a unity of counsel.
